Hot device 1, Oil Tank side be equipped with liquid level gauge 21, Oil Tank be provided with clean-out opening 19, Oil Tank top be respectively provided with return filter 15,
Oil filler 16, liquid level alarm 17 and temperature alarm 18；
In the side lower part of Oil Tank one equipped with two petroleum pipelines, petroleum pipeline passes through oil cleaner screen 2, ball valve 3, motor 4, hydraulic pump 5, report
Alert 6 points of two-way of oil cleaner screen are connected by overflow valve 12 with flow flow speed control valve 13, and flow flow speed control valve passes through hand-operated direction valve 14 and the
Hydraulic oil, is input to after solenoid directional control valve 11, then inputted by hydraulic lock 9 by one pump and the connection of the second pump by hand-operated direction valve
Into jacking hydraulic cylinder 10, pressure gauge 7 is connected with by pressure gauge valve 8 in hydraulic lock.
A whole set of opening-closing device connects hatch board by jacking hydraulic cylinder.
Function of the present utility model is with using：
1st, hydraulic lifting unit function：
1. oil temperature is low alarms with oil temperature height：The thick pump of the low fluid of oil temperature is difficult to oil suction, reduces service life, fluid when oil temperature is high
Dilute easily oil suction, can not produce lubrication, reduce service life；
2. heating function：50 degrees Celsius of automatic disconnect are heated, and less than 30 degrees Celsius can manually start heating, 50 degrees Celsius
Heating can not be manually started above；
8. oily dirty alarm：Protect No. 1 oil pump to be used with No. 2 oil pumps and the normal of oil cylinder respectively, and extend pumping plant and oil
The service life of cylinder；
4. oil level height is alarmed：When oil level is high, automatic alarm adjustment oil level can be used normally.When oil temperature is low, automatic report
Alert adjustment oil level, can normally be used；
5. motor overvoltages decompression（Voltage）And misconnection facies pattern can not start.
2. hydraulic lifting unit operating instruction：
1. connect untill electric panel power indicator lamp lights, any two are overturned per bright three live wires；
2. before not refueling, panel oil level is in alarm condition, oil is added to liquid level gauge more than half
Use；
3. the knob on panel is screwed to 1 pump position.Start by 1 pump motor on panel, if 1 pump alarm lamp is lighted,
Knob is then screwed to 2 pump positions, started by 2 pump motors on panel；
4. panel, 1 pump or 2 pumps are observed, the switching valve in the lower left corner are moved to the position of respective pump；
5. it is determined above errorless, panel epicoele or cavity of resorption commutation can be pressed（Epicoele declines for hydraulic cylinder, and cavity of resorption is fluid
Cylinder rises）.
3. hydraulic lifting unit points for attention：
1. first refuel and check whether connector is reliable afterwards, errorless rear wiring trial operation；
2. motor must reliable ground；
3. motor positive and inverse is noted during pump wiring；
4. hydraulic oil：The hydraulic oil that hydraulic system is used is recommended, 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, and fresh oil should be changed in time.
Liquid level is preferably located in the middle part of liquid level gauge during use, if less than the position, should refuel in time.
5. the wiring of electronic box：The line of 3 phase 4 is accessed, if power supply indicator does not work, and is observed phasic property protector, is checked whether there is
The phenomenons such as overvoltage, decompression, phase shortage.
6. system exhaust：If being mixed with air in hydraulic cylinder or pipeline, it may appear that creep or jitter phenomenon, therefore formally transporting
First dry running is needed before row 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, can raise system maximum working pressure (MWP), and screwing out regulation can make system maximum
Operating pressure is reduced.Maximum design pressure is not allowed more than during regulation pressure, and after remembeing that regulation is finished, locking nut is twisted
Tightly, in order to avoid loosening.
