Two sealed spaces are formed in the two spaces of the oil pump body and the front and rear covers. The rotating gears and the space for gear disengagement have increased from small to large, vacuum, liquid, and high pressure. The oil pump uses a car suction pump to suck away the fuel in the truck parked on the road. If used for a long time, the filler will be consumed, because the push rod will loosen, and the pump's sand bag will generate a lot of water. The air is exhausted from a series of open spaces. As a result, the outside air from these open spaces enters the interior of the pump, which affects the upward lifting of the water. First of all, oil pump motors and jacks should use ordinary oil for operating oil, such as 10 or 20 mechanical or transformer oils, and should also be used with other hydraulic oils that are close to nature. The oil in the tank needs to be filtered. When they are used often, they are filtered once a month, and a fuel tank is cleaned over time. The fuel tank usually needs to be fixed at about 85% of the oil level, and if there is a shortage, it needs to be corrected within time. The temperature of the oil in the fuel tank should generally be 10 to 40 pounds and should not be used at negative temperatures.
The oil pump and jack are connected to the oil tank to keep it clean. When not in use, sand enters the screw and is broken. The jack begins to expose the nozzle oil and grease cap. The screw cap is sealed, and dust and garbage are not allowed to enter. After daily use, wipe the oil pump clean to remove the grease from the copper wire cloth. Do not allow the oil pump motor to work under overload conditions. The safety valve can adjust the pressure according to the excess oil pressure of the device to prevent arbitrary adjustment. Keep the fuel tank connected to the oil pump and the jack clean. If not in use, plug the sand with screws to seal the oil nozzle and lubrication cap exposed by the jack.
