一、Product description
Ultrahigh pressure large-tonnage jacks is a kind of ZB type
high-pressure pump as power sources of electric hydraulic jack,
for heavy machinery, bridge engineering, water conservancy,
port construction and other industries of lifting equipment. ,
with large output force, light weight, long operating
characteristics of ultra-high pressure pump station with the
plant, which can realize the top, push, pull, extrusion, and
other forms of homework, in recent years has been in the
foundation settlement test and static pressure pile has been
widely used.
二、Method of use
1, if less than the volume of oil pump body, need to be the first
to add work oil pump (10 # engine oil) to work.
2, estimate the weight, avoid by all means use overload.
3, determine the weight of the center of gravity, choose jack
focus, at the same time must consider the ground to tough wood
is the hard and soft mat, lest produce when lifting the danger
of dumping.
4, jack will clog jack-up, immediately with tough wood will
weight support in mind, it is forbidden to jack used as supports,
in order to avoid load imbalance, produce the danger of dumping.
5, when using manual pump first quick connector and docking,
and then choose the right position, the oil drain screw
tightening on the oil pump, can get a job. Unscrew the oil drain
screw, oil cylinder unloading.
三、Matters needing attention
A) when used as a empty phenomenon, can relax first oil drain
screw on the pump body, pump body vertical up head down to play
a few times, then tighten the oil drain screw, can continue to
use.
B) when a load, avoid by all means will be fast connection, so
as to avoid an accident and damaged parts.
C) this machine is oil as medium, oil and the machine
maintenance work must be done well, so as to avoid silting up
or oil leakage, affect the use effect.
D) new or long rear hydraulic jack, because of the oil cylinder
is memory is more air, began to use the piston rod may appear
tiny kick phenomenon, hydraulic jack no-load reciprocating
motion can be 2-3 times, to eliminate the air cavity. Idle jack
for a long time, due to seal the seal for a long time didn't
work hardening, which affects the service life of hydraulic
jack, so hydraulic jack in need not when, on a monthly basis
to hydraulic jack light reciprocating movement 2-3 times.
四、Matters needing attention in operation and maintenance
1, the working medium of the pump for YC - N46D hydraulic oil,
32 # anti-wear hydraulic oil, also can use 10 # transformer oil,
but is allowed to change to use other brand of oil.
2, used for the first time, fill up after the motor should be
clockwise rotation, if necessary, please open the machine cover,
whether as a forward, and several times, please point still
motor idling for a few minutes, in order to vent air from oil.
3, tank liquid level in oil mark the center line of the above,
in case of oil pump suction empty. Come on when the application
of 120 mesh strainer filter to the impurity in the oil. Often
use, once every two months to clean oil filter, tank cleaning
once half a year, and replace the new oil.
4, normal working oil temperature of 20-70 ℃. Cooling measures
should be taken when the oil temperature is too high or stop
pump, after waiting for the oil cooled sufficiently to use; The
oil temperature too low is not allowed to work directly, need
heating measures, by heat or low voltage operation to improve
the oil temperature.
5, before starting the machine, need to open the unloading valve,
in case the motor overload. When the system is for multiple
directional control valve export more, more attention should
be paid to open the unloading valve, pump working normally
closed after unloading valve, then throw the reversing handle
to switch the direction of oil flow.
6, jack can't overload is used, the base and top of weight,
vertical with the bearing pad fixation (if vertical jack-up not
fixed), joint should be avoided in the process of handling and
use of violent vibration, tighten handle ring screw, before
handling this product should not be working in a corrosive
environment.
7, this pump factory sort of working pressure shall not be
arbitrarily raising. Directional control valve, general
operating force does not exceed 100 n and accurate operation,
due to the reversing direction and hose connection unlimited,
so reversing valve should be familiar with when using
commutation position.
8, high pressure hose factory to withstand voltage test, test
pressure is 1.25 times the rated, but when used for a long time,
due to the aging of colloid, around the damage causes of hose
compression strength of lower, should pay attention to
regularly check, use frequently check once every six months.
Check with testing pump pressure, when pressure is lower than
1.25 times the rated pressure leak, bump or blasting must be
replaced. High pressure hose when using, should avoid sharp
discounts and appeared, the operator should pay attention to
not being too close to hose, in order to avoid blasting thrown
up here. In the fixed occasions, can be substituted for steel
pipe.
9, this pump maintenance once a year. Wash all parts with
kerosene, pay attention to protect the parts surface, may not
be any knock against, after the assembly, all moving parts
should be flexible, no local resistance.
