Specific implementation mode
Hydraulic lifting unit operation step：
1, the high-pressure rubber pipe of device is connected respectively to the inlet and outlet of hatchcover jacking apparatus oil cylinder；
2, it connects until electric panel power indicator light lights, does not have bright three firewires to overturn arbitrary two；
3, before not refueling, panel oil level is in alarm condition, and the half for oil being added to liquid level gauge uses；
4, the knob on panel is screwed to the first pump position.Start by the first pump motor on panel, if the first pump report
Warning lamp lights, then knob is screwed to the second pump position, starts by the second pump motor on panel；
5, panel, the first pump or the second pump are observed, the switching valve in the lower left corner is moved to the position of respective pump；
6, nothing determined above is mistaken, and presses panel epicoele or cavity of resorption commutation, epicoele decline for hydraulic cylinder, cavity of resorption is fluid cylinder
Rise.
Hydraulic pressure unit used is constituted：
Oil Tank 20 is housed on pedestal 23, the lower part of Oil Tank is equipped with fuel outlet 22, and heater 1 is housed in Oil Tank inner cavity,
Oil Tank side is equipped with liquid level gauge 21, and Oil Tank is equipped with cleaning hole 19, and Oil Tank top is respectively provided with return filter 15, oil filler
16, liquid level alarm 17 and temperature alarm 18；
Two petroleum pipelines are housed in one side lower part of Oil Tank, petroleum pipeline passes through oil cleaner screen 2, ball valve 3, motor 4, hydraulic pump 5, report
Alert oil cleaner screen 6 divides two-way to be connect with flow speed governing valve 13 by overflow valve 12, and flow speed governing valve passes through hand-operated direction valve 14 and the
One pump and the second pump connect, and after hydraulic oil is input to solenoid directional control valve 11 by hand-operated direction valve, then are inputted by hydraulic lock 9
Into jacking hydraulic cylinder 10, pressure gauge 7 is connected with by pressure gauge valve 8 in hydraulic lock.
Hydraulic lifting unit function：
It alarms with oil temperature height 1. oil temperature is low：The thick pump of the low fluid of oil temperature is difficult to oil suction, reduces the service life, fluid when oil temperature is high
Dilute easily oil suction, can not produce lubricating action, reduces the service life；
2. heating function：50 degrees Celsius automatic to disconnect heating, and 30 degrees Celsius or less can manually start heating, 50 degrees Celsius
Heating can not be manually started above；
3. the dirty alarm of oil：The normal use of l oil pumps and No. 2 oil pumps and oil cylinder is protected respectively, and extends pumping plant and oil
The service life of cylinder；
4. oil level height is alarmed：When oil level is high, automatic alarm adjusts oil level, can normal use.It is automatic to report when oil temperature is low
Alert adjustment oil level, can normal use；
5. motor overvoltages decompression (voltage) and misconnection facies pattern can not start.
Hydraulic lifting unit points for attention：
Check whether connector is reliable afterwards 1. first refueling, errorless rear wiring trial operation；
2. motor must reliable ground；
Pay attention to motor positive and inverse when 3. pumping wiring；
4. hydraulic oil：The hydraulic oil that hydraulic system uses recommends, winter HC-32# antiwear hydraulic oil, summer HC-46#
Antiwear hydraulic oil is refueled before refueling with by oil filter, and oil filler is located at Oil Tank upper cover plate, and equipped with air cleaner, pair is added
The oil for entering Oil Tank carries out a coarse filtration again, if being found during use, oil emulsifying or impurity are excessive, should replace fresh oil in time.
Liquid level is preferably located in the middle part of liquid level gauge during use, if being less than the position, should be refueled in time.
5. the wiring of electronic box：3 phase, 4 line accesses, if power supply indicator does not work, observes phasic property protector, checks whether there is
Phenomena such as overvoltage, decompression, phase shortage.
6. system exhaust：If hydraulic cylinder or pipeline Cao are mixed with air, it may appear that creep or jitter phenomenon, before commencement of commercial operation
Need first dry running more than twice.
7. pressure is adjusted：The maximum pressure of system work is determined by overflow valve, in the regulation handle for first unclamping overflow valve
Locking nut screws in the release handle of regulation relief valve, and system maximum working pressure (MWP) can be made to increase, and screwing out to adjust can make system maximum
Operating pressure reduces.Maximum design pressure is not allowed more than when adjusting pressure, and after remembeing adjusting, locking nut is twisted
Tightly, in order to avoid loosening.
