The reason why the gear oil pump does not produce oil. The gear oil pump is suitable for conveying various lubricating liquids. The temperature is not higher than 70 ° C. If a high temperature of 200 ° C is required, high temperature resistant materials can be used. This pump is not suitable for conveying corrosive, hard particles or fibers, highly volatile or low flash point liquids, such as gasoline and benzene.
Gear oil pump The gear pump uses two gears to rotate with each other to work, and does not require high media. The general pressure is below 6MPa, and the flow rate is large. The gear oil pump is equipped with a pair of rotary gears in the pump body, one active and one passive. Relying on the mutual engagement of the two gears, the entire working chamber in the pump is divided into two independent parts.
The hydraulic pump will inevitably fail after being used for a period of time。 The gear oil pump is widely used。 Then what is the reason why the gear oil pump is not oiled?
A gear oil pump is a device that converts mechanical energy into hydraulic energy through a pair of gears that mesh with each other. It is widely used in the lubrication system of air compressors. The failure of the oil pump in operation is usually the decrease of the oil pressure in the lubrication system, and sometimes even the oil cannot be played.
The main reasons are: the direction of rotation is opposite to the specified direction; the oil suction line is not tight and the check valve is stuck; the seal between the pump body and the pump cover of the oil pump is poor; the amount of oil in the oil tank is insufficient; the oil pump parts are seriously worn; the oil suction filter Was blocked。
The actual work should be handled differently according to the specific situation。 Special attention should be paid to the seal of the oil suction pipeline and the seal between the pump body and the pump cover of the gear oil pump during the maintenance。 If the suction end is poorly sealed, air will leak into the oil pump inlet, causing the oil pump to evacuate, and naturally no oil will be discharged。
