PROPERTIES TO BE CARED DURING CARRYING, SHIPPING AND STORAGE

Rules which are mentioned in user manual should strictly be obeyed for not causing accidents.

Protective gloves, shoes and helmet should be used during shipment and carrying.

Crane and lifting ropes which are suitable with hydrophore volume and weight and structure should be used.

Following aspects should be considered before lifting hydrophore or hydrophpre or motor group over frame.

- Total weight and center of gravity

- Maximum external dimension

-Locations of lifting points

Capacity of machines etc objects should be suitable with weight of hydrophore and hydrophore group.

Hydrophore or hydrophore group should always be lifted vertically.

You should never stay near under or close to pump during hydrophore lifting.

Lifting operations of hydrophores should be short as possible.

Accelerating and braking operations during lifting should be performed such that it will not cause any harm for the personnel working for this operation.

-9-

Hydrophore should be protected against contracts and hard impacts while they are loading to transportation vehicles.

Necessary fixing and anchoring materials should be used for the machines which are loaded to transportation vehicles for preventing crashes and contacts.

Hydrophore nameplates should absolutely be controlled while they are being received.

Figure 1a. Only Hydrophore Figure 1b. Common Hydrophore and Motor over frame

Hydrophores should be lifted as it is shown in drawings Figure 1.a and Figure 1.b for not causing any danger and deformation during transportation.

The area where hydrophore will be stored should be clean, dry and should not include frost hazard and ambient temperature should not change so frequently.

Necessary precautions should be taken for preventing hydrophore against dust, dirt and foreign objects.

Shaft should be rotated in definite time intervals for preventing pitting in hydrophore shaft and bearings.

-10-

RULES WHICH SHOULD BE OBEYED IN HYDROPHORE INSTALLATION

WORKING PLACE:

Hydrophores should be carried over a flat and robust ground.

Working places of hydrophores should be closed such that they will not be effect from environmental conditions such as rain, frost.

Hydrophores should not be effected from temperatures of other equipments and machines around them.

Required space should be adjusted around hydrophore for maintenance and repair operations.

If hydrophore is supplied from a tank, there should be maximum 10 mt distance between tank and hydrophore.

SUCTION INSTALLATION:

Supply in hydrophores should be done by water tank. Waterworks should not be used directly.

Suction pipe should be short as possible.

A filter having quality and property which will permit the water passing with internal diameter area of suction pipe should be selected.

Filter with backwater valve and auxiliary parts should be connected to suction pipe provided that they will not take air and have water impermeability and suction pipe should be connected to hydrophore after bending and having a wide angle as possible.

-11-

Water tank and hydrophore connection should be in same plane. So there will always be water in hydrophore suction.

Suction should never be performed from lower levels of hydrohore plane. Damages which may be caused from such applications are not included within warranty.

Impermeability should be provided in suction lines of hydrophores, air should not enter into suction line.

As hydrohphores are designed for ready water suction, suction should not be performed by hydrophores. Water suction should be one fold greater in single hydrophores and should be equal to collector diameter in two or more hydrophores system.

If hydrophore is supplied from a tank whose level is higher than hydrophore, an isolation valve whose axis should be horizontal with suction pipe should be used. This valve should always be in open position while hydrophore is operating and should never be used as adjustment valve.

Closing valve may cause hydrophore operate with cavitations.

If suction pipe is plastic pipe, pipe whose diameter is suitable with galvanized pipe should be selected since the diameters of plastic pipes are narrower than galvanized pipes.

If there is the necessity of cross section change in a horizontal suction pipe, an eccentric conical part whose flat part is at upper side should be used.

Suction pipe should absolutely be impermeable and arranged to prevent the formation air peripheries. So if hydrophore is supplied from a tank whose level is higher suction pipe should have a slope which slightly decrease towards hydrophore and if it is supplied from a tank whose level is lower, suction pipes should have a slope which slightly increase towards hydrophore.

-12-

For minimizing the pipe friction losses as possible, sharp curves should not be used, and sudden direction and section changes should be avoided. If there is the necessity of section change in a horizontal pipe and eccentric intermediate part whose flat side will be at upper side should be used.

DISCHARGE INSTALLATION:

A control valve is connected to discharge pipe line, in a level which is very close to hydrophore as possible for adjusting flow rate and discharge height.

If discharge height of hydrophore is more than 10 mt or discharge line is very long, a check valve should be connected over discharge pipe line between hydrophore and isolation valve for preventing motor against water impacts and reverse flow during hydrphore stopping.

Installation of suction and discharge line is given below as schematics.

1- Hydrophore 2- Float Valve 3- Valve 4- Check Valve 5- Drain 6- Discharge 7- Dirt retainer 8- Console Tap 8- Level FLoater

-13-

OTHER INSTALLATION CONDITIONS:

Backwater valve should be installed at suction part of hydrophores. This will prevent the entrance of solid particles to hydrophore and its parts during suction.

Silt traps which are used at the end of suction pipe should be cleaned periodically. Otherwise foreign objects which ma come to hydrophore suction may clog the suction and prevent water entry to hydrophore suction.

Valve should be installed in hydrophore inlet and valve and check valve should be installed at hydrophore outlet. By means of this application separation of hydrophore from installation will be possible during repair and maintenance operations.

Curves which are used in suction and discharge lines should have wide angles as possible.

Pipe connections should be made by flanges. Flange seals should be made from suitable materials and should have proper sizes. Flange seals should be centered as they will not prevent flow.

Connection of hydrophore to installation by means of flexible hoses should be preferred. So loads which may be caused by installation will not reflected to hydrophore. Also vibration and sound of hydrophore will not pass to the installation.

Hydrophore should be fixed to ground by bolts during operation. So sound which may occur during operation is almost prevented.

In case that suction and discharge lines are long, bedding should absolutely be done in bearings. Otherwise it will cause shocks and vibrations.

-14-

PROPERTIES OF USED LIQUIDS:

Water is used as fluid in hydrophores. Clean water should not include particles. Liquid temperature should be between 0-350C

Ambient temperature should be maximum 400C

Water inside hydrophore should be protected from frost hazard. Damages which may be caused by frost are out of warranty.

PRECAUTIONS WHICH SHOULD BE TAKEN FOR ELONGATING THE USAGE TIME OF MECHANICAL SEAL

Mechanical seals are one of the weakest part of hydrophores. Incorrect installation and usage may cause rapid breakdowns. Operational life time of mechanical seal is 8000 hours in waters which does not include particles in

normal operational period. As an operational principle; it forms a film layer between carbon and ceramic or stainless surface and ensures contact of those surfaces without friction. Water also has cooling function. However, if water film does not form and mechanical seal surface runs for few minutes without water, this cause burn of mechanical seal and break down in 3-5 minutes.

PRECAUTIONS WHICH SHOULD BE TAKEN FOR HEALTHY OPERATION OF MECHANICAL SEAL

Hydrophore should not make suction from low levels.

Check valves should not be used in hydrophore connections whose suction level is same with tank. Check valve makes flow difficult. Also filter which locates in suction part should frequently be cleaned for preventing clogging.

Sand which presents in water may tear water film and provides break down in impermeability.

-15-

ELECTRICAL CONNECTIONS

Electrical connections should only be done by authorized service personnel.

Current national regulations and instructions of motor manufacturer should be obeyed in hydrophore installation.

Precautions which are mentioned in "USAGE PRINCIPALS" should be obeyed. All electrical connections should be disconnected before making any operations over hydrophore.

Installation of power cables should be performed such that they will not have contact with pipe, hydrophore and motor part.

Voltage, frequency and ampere values which are written in nameplate should be checked whether they are suitable with line values.

Circuit breakers and fuses should be used for preventing motor operate overloaded.

Pump shaft should be checked whether it rotates easily before giving power to motor.

Motor electrical connections should be done according to Electricity Regulations and grounding should strictly be done.

Motor connection scheme is included in user manual and motor connection box.

Motor connection types are given in Table 1 and Figure 2.a,2.b, 2.c In cases that electrical connections are incorrect and failures which are caused by power supply unit will make pump unit become out of warranty.

Transition time from star to delta should be very short in star/delta connected motors. Otherwise this may cause damage in pumps.

Rotate the hydrophore rotor manually for few turns after abovementioned operations are completed for being sure that it rotates easily.

All guards are installed in their places before hydrophore starts to run. Motor should not absolutely be started before guards are placed into their places.

Cables coming from electricity unit to pump are isolated and protected.

Pumps and cable connections should not be contacted out of expert pr responsible personnel and without switching off power from main circuit breaker; For preventing the damages which may be caused by electrical leakages which may occur pump connection an cables.

-17-

PUTTING HYDROPHORE GROUP INTO SERVICE

SEMPA LTD .ŞTİ. authorized services are responsible for performing first start operations.

Grounding of hydrophore system should be done.

Electrical leakage control should be done.

Line voltage should be measured.

Check whether there is sufficient water inside tank.

Thermal protection adjustments should be controlled.

Be sure that installation of membrane tank is correct and control the appropriateness of preliminary pressure.

Completely open the valve in hydrophore suction part.

Slightly loosen the air take plug of hydrophore. If the water level in water tank is higher than this level, water will leak from the plug for a while. If hydrphore will operate with suction, fill water from this part and tightly close the plug.

Run the hydrophore or hydrophores for a short while. Check whether hydrophore shaft rotates in correct direction. If hydrophore rotates in reverse direction change the places of electrical connection terminals.

Check whether hydrophore or hydrophores in requested pressure interval.

Check rotation is performed in every operation in hydrophores having multi-pumps.

PUTTING HYDROPHORE INTO SERVICE OPERATION HAS FINISHED

-18-

PUTTING HYDROPHORE GROUP OUT OF SERVICE

Slowly close the discharge valve

If there is equipment for preventing and impulse is not in dangerous, you can directly stop hydrophore without closing the discharge valve for preventing water hammer.

Stop the pump. Control the motor stop whether it has stopped regularly.

Control whether there is water leakage from mechanical seal after hydrophores have put out of service.

If hydrophore will be out of service for a long time close the suction valve and other auxiliary pumps.

If there is frost risk in the environment where hydrophore locates, water inside pump should absolutely be discharged and necessary precautions should be taken.

CONTROLS WHICH ARE NECESSARY TO BE DONE IN WATER PUMPS DURING OPERATION

Hydrophore should operate regularly, silent and without vibration.

Hydrophores should never be operated without water.

Pumps should not operate in completely closed valve condition for a long time.

Take care that all valves belonging to auxiliary systems are open during hysrophore operation.

Hydrophore will not need any maintenance if it is operated with mechanical seal. Leaked water is so low that it can not be seen. Increase in drops from mechanical seal means that surfaces are abraded and needs to be changed. Lifetime for mechanical seal usage depends on cleanness of water.

-19-

Control the clutch materials between motor and hydrophore periodically. If there are abraded materials replace them with newer ones.

Periodically control the motor current. If motor current is less than occasional values stop the motor. There may be jamming in motor and hydrophore accessories. Run the hydrophore after making necessary repair and maintenance operations and according to necessary safety precautions.

Hydrophores which are used as spare should be run at least once a week and systems related with this should be controlled.

No Operation should be done over hydrophpres while hydrophores are operating. Centrifugal Hydrophores should not be started in particular when guards and protective materials are not installed.

PRESSURE BALANCING TANK (MEMBRANE TANK)

There are different applications pressure tanks that are used in hydrophores depending on size and tonnage of hydrophores.

User should use membrane tank with hydrphore in SPK, SPS and SPL series. Selection of membrane tank, installation and pressurizing is explained below.

-20-

VOLUME CALCULATION OF MEMBRANE TANK

Total volume calculation for replaceable expansion membrane tank which is used in hydrophore system is calculated as following.

VE=0,33 X Qmax(PA+1) (m3) ΔP(A.E)vXS Qmax= Maximum flow rate of hydrophore (m/h) PA= Upper pressure of Hydrophore operation (Bar) P(A-E)=Hydrophore operational interval (Difference between upper pressure and lower pressure) Bar S=Number of switching (Number of starts and stops of Hysrophore in one hour)

Minimum usage pressure of tank is found after calculations. There is no problem if operational pressure is calculated high. On the contrary following benefits may occur as the tank volume increases.

Pressure fluctuations in water decrease.

Lifetime of motor becomes longer.

Energy costs decrease.

Sound of motopump start stop decreases as the number of hydrophore switching number will decrease.

Notice: As it is defined by the general instructions which is published by Ministry of Public Works:

Number of switching up to power max 1.1 kW motor power is 180 times/hour

Number of switching up to power more than 1.1 kW motor power is 40 times/hour

Notice: Maximum operational pressure of membrane tank should be higher than maximum operational pressure of hydrophore. CONNECTION OF MEMBRANE TANK Aim of pressure membrane tank is to decrease the number of start and stops in one hour. There will not be necessity of motopump for usages in low amounts. Therefore the greater tank the less number of switching.

-21-

Connection of membrane tank to hydrophore unit is performed in two ways. 1- Collector Connection There is tank connection outlet over hydrophore discharge collector. Pressurized tank can be connected here by means of steel cord flexible hose, galvanized or plastic pipes. Pipe installation having minimum diameter of outlet of membrane tank should be used at hydrophore discharging pipe. Otherwise water transmission speed between tank and installation decreases. This may cause decrease in efficiency of tank and may cause problems in hydrophore operation. 2-Connection to Installation

It is possible to connect pressure tank directly to installation. If hydrophore is directly connected to installation, end of membrane tank in collector should be closed. Distance of pressure tank to hydrophore group should not exceed 5(five) meters. If distance increases sense of pressure switch is delayed and there may be irregularities in operation. PRELIMINARY GAS PRESSURE ADJUSTMENT OF PRESSURE TANK Hydrophore unit is not absolutely used without tank. Tanks with membranes are used for this purpose provided that they are suitable with operational pressure. There is a little air inside tanks with membrane during transportation and shipment. Air pressures of membrane tanks should be adjusted according to usage conditions. Tank pressure is practically calculated as following. Pö=Pst-0.5(Bar) Pö=Hydrophore preliminary pressure Pst=Tank Pressure

Connection of hydrophore with installation should not be disconnected during air injection and if there is water inside hydrophore it should be discharged.

Using galvanized tanks which has direct contact with air is inconvenient for usage as hydrophore tank. As air inside tank dissolves in water leaks to outside with air. Therefore air inside tank finishes and as a result of this number of motor switching over increases.

Air inside membrane tank should periodically be controlled. If the pressure inside tank decreases, number of hydrophore switching will increase therefore sound and water fluctuation will increase.

-23-

PRESSURE SWITCH

Pressure switches are used for adjusting operational pressures and stop pressure

PRESSURE SWITCH ADJUSTMENT

There are two pieces of spring screws in pressure switches. Longer one is used for pressure adjustment and shorter one is used for adjusting stop pressure.

1- Loosen the shorter screw till the end.

2- Adjust the hydrophore start pressure by longer screw.

3- As a final operation tighten the shorter screw the shorter screw up to your preferred stop pressure.

There is approximately 3 seconds of delay in two or more hydrophore systems for preventing water hammer. This property should be considered during adjustment in hydrophores

Pressure should not be increased so much in hydrophore while making pressure switch adjustment.

-24-

PROTECTION AGAINST OPERATION WITHOUT WATER

Float valve system is used to take precautions for preventing hydrophore operate without water. Hydrophore makes suction as the float valve is suspended in water. If water inside tank finishes, float valve will fall down and suction will not occur.

Float valve system should absolutely be used in hydrophore systems with tank for preventing pump operate without water. Otherwise, if there is not water in tank, pump will operate without

water . Pump unit will be out of warranty if is works without water.

DISMOUNTING OF HYDROPHORE; REPAIR AND MAINTENANCE

DISMOUNTING OF HYDROPHORE

Switch the main circuit breaker off which is at energy inlet of motopump.

Uninstall electrical cables and be sure that they will not mistakenly be connected.

Switch off the fuse in pump panel which is related with hydrophore.

Remove the hydrophore motor connections.

Close the isolation valve which are in discharge and suction line.

Uninstall the clutch and other safety guards

Close the valve which is at water inlet and separate pump from flange.

If there are pumps more than one in system each operations are repeated for the hydrophore to be unintalled. And system should be powered on after this operations are completed.
