1. What is the working principle of the gear oil pump?
1. The gear pump is a pump used for conveying oil. The pump body has a pair of meshing gears, one is the driving gear, the other One is the passive gear.
2. Due to the meshing of the two gears, the working chamber of the pump is divided into two independent parts, one side is the suction chamber and the other side is the discharge chamber.
3. When the gear oil pump works, the driving gear rotates the driven gear, and when the gears are engaged and disengaged, a partial vacuum is formed on the suction side, and the liquid is sucked in.
4. The sucked liquid fills the gears and is brought to the discharge side. When the gears come into meshing, the liquid is compressed to form high-pressure liquid, and is discharged from the pump through the discharge port of the pump.
Second, operating procedures for gear oil pump
Gear oil pump is a kind of gear pump, which is mainly suitable for conveying various lubricating liquids. , shaft, pump body, pump cover, bearing sleeve, shaft end seal, etc. To operate the gear oil pump, you need to master the correct operation method, and strictly follow the gear pump operating procedures to operate:
1. The gear oil pump should be When using the working oil of the specified oil number, the oil poured into the oil tank must be filtered first, the oil tank should be cleaned regularly, and the oil level should be maintained at about 85%.
2. The exposed oil nozzle of the gear oil pump should be sealed with a nut to prevent dust and debris from entering the machine. After use, the gear oil pump should be wiped clean, and the grease on the oil filter copper wire cloth should be cleaned in time. .
3. The gear oil pump should not work under overload. The pressure of the safety valve must be adjusted according to the rated oil pressure of the equipment, and cannot be adjusted arbitrarily without permission.
4. Before running the high-pressure gear oil pump, loosen the control valves of each oil circuit, and then start the gear oil pump. After the no-load operation is normal, close the oil return valve tightly, and gradually screw the oil inlet valve. lever, increase the load, and pay attention to whether the pressure gauge pointer is normal.
5. When stopping the operation of the gear oil pump, the oil return valve should be slowly loosened first, and the oil pipe joint nut of the jack should be removed after the pressure gauge slowly returns to the zero position.
6. The oil pipe of the gear oil pump should avoid bending, pay attention that the working pressure should not be higher than the rated oil pressure of the gear oil pump or the maximum oil pressure of the actual work, and the length should be less than 2.5m.
