Abstract
The invention provides a method for temporary open and close of a bulk cargo cabin hatch cover. A high-pressure rubber pipe of a device is connected to an inlet and an outlet of a cylinder of a hatch cover lifting device separately; a power indicator on a faceplate is connected with power until the power indicator lights; if the power indicator does not light, any two of three fire wires are reversed; and before oil is added, the oil level of the faceplate is in a state of alarming, and then the oil is added to half of a liquid level meter to be used. A rotary knob on the faceplate is wrung to the position of a first pump, and then a motor of the first pump on the faceplate is pressed to start; if an alarming light of the first pump lights, the rotary knob is wrung to the position of a second pump, and then the motor of the second pump on the faceplate is pressed to start. The faceplate is observed, whether the rotary knob is wrung to the first pump or the second pump is observed, and then a conversion valve in the lower left corner is turned to the position of the corresponding pump; when it is determined that the above steps are errorless, an upper chamber or a lower chamber of the faceplate is pressed to change the direction; and pressing the upper chamber indicates the decline of a hydraulic cylinder, and pressing the lower chamber indicates the rising of an oil cylinder. A hydraulic unit is used for open and close of the cabin hatch cover. The method is suitable for the temporary open and close of the bulk cargo cabin hatch cover.

Specific embodiment
Hydraulic lifting unit operating procedure：
The 1st, the high-pressure rubber pipe of device is connected respectively to the import and export of hatchcover jacking apparatus oil cylinder；
2nd, connect till electric panel power display lamp lights, do not have bright three live wires to overturn any two；
3rd, before not refueling, panel oil level is in alarm condition, and the half that oil is added to liquidometer is used；
4th, the knob on panel is screwed to the first pump position.Start by the first pump motor on panel, if the first pump alarm lamp
Light, then knob is screwed to the second pump position, start by the second pump motor on panel；
5th, panel, the first pump or the second pump is observed, the switching valve in the lower left corner is moved to the position of respective pump；
6th, nothing determined above is mistaken, and presses panel epicoele or cavity of resorption commutation, and epicoele declines for hydraulic cylinder, and cavity of resorption is on fluid cylinder
Rise.
Hydraulic pressure unit used is constituted：

Side is equipped with liquidometer 21, and Oil Tank is provided with clean-out opening 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 is by oil cleaner screen 2, ball valve 3, motor 4, hydraulic pump 5, filter of reporting to the police
6 points of two-way of oil network are connected with flow flow speed control valve 13 by overflow valve 12, flow flow speed control valve manually reversal valve 14 and the first pump
Connect with the second pump, manually reversal valve is input to hydraulic oil after solenoid directional control valve 11, then is input to top by hydraulic lock 9
Rise in hydraulic cylinder 10, pressure gauge 7 is connected with by pressure gauge valve 8 in hydraulic lock.
Hydraulic lifting unit function：
1. oil temperature is low is reported to the police with oil temperature height：The thick pump of the low fluid of oil temperature is difficult to oil suction, reduces service life, fluid dilute pole when oil temperature is high
Easily oil suction, can not produce lubrication, reduce service life；
2. heating function：50 degrees Celsius automatically disconnect heating, and less than 30 degrees Celsius can manually start heating, more than 50 degrees Celsius
Heating cannot be manually started；
3. oily dirty warning：The normal use of l oil pumps and No. 2 oil pumps and oil cylinder is protected respectively, and extends pumping plant with oil cylinder
Service life；
4. oil level height is reported to the police：When oil level is high, automatic alarm adjustment oil level normally can be used.When oil temperature is low, automatic alarm is adjusted
Whole oil level, normally can use；
5. motor overvoltages decompression (voltage) and misconnection facies pattern cannot start.
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：Hydraulic system using hydraulic oil recommend, winter HC-32# antiwear hydraulic oil, summer, HC-46# was wear-resistant
Hydraulic oil, with being refueled by oil filter before refueling, oil filler is located at Oil Tank upper cover plate, and air filter is housed, to adding oil
The oil of cabinet carries out a coarse filtration again, if finding during use, oil emulsifying or impurity are excessive, should change fresh oil in time.Use
During liquid level be preferably located in the middle part of liquidometer, if be less than the position, should refuel in time.
5. the wiring of electronic box：3 phase, 4 line is accessed, if power supply indicator does not work, is observed phasic property protector, is checked whether there is
The phenomenons 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, is first unclamped in the regulation handle of overflow valve
Locking nut, screws in the adjusting tap of regulation relief valve, raises can 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 when adjusting pressure, and after remembeing that regulation is finished, locking nut is twisted
Tightly, in order to avoid loosening.
