VIKING gear pump Is a common hydraulic pump, is widely used in the industrial field. However, due to long-term use or other reasons, VIKING Gear pump Some common faults may also occur. These failures may lead to abnormal working conditions of the pump and affect the working efficiency of the production line. Therefore, in this article, we will introduce the common faults and solutions of VIKING gear pump, to help you eliminate faults in time during maintenance.

1、 Common faults of VIKING gear pump

Pump body leaks oil

Viking Oil leakage of pump body is one of the common problems of VIKING gear pump. The oil leakage of the pump body is caused by the damage or wear of the sealing structure in the pump body. External air enters the pump body, causing the pressure to be unstable or the pump body to fail to work normally.

The inlet valve is severely worn

If the inlet valve is excessively worn, the pressure in the pump may be unstable or the pump body may not work properly. This is usually caused by the long service time of the inlet valve, frequent switching or particles entering the pump.

Shaft seal wear

The shaft seal is an important sealing structure in the pump. If it is excessively worn, the service life of the pump will be affected, and the shaft seal will leak or seep.

The suction tube sensor is damaged IMO

The suction pipe sensor is used to measure the lift, temperature, pressure and other parameters of the suction pipe of the pump. The common fault is that the sensor is damaged, resulting in abnormal data or no data can be read.

2、 Solution

Oil leakage treatment method of pump body

The oil leakage treatment method of pump body is usually to repair the pump body with sealing materials. First, the sealing surface must be cleaned to ensure perfect repair of the sealing surface. Then, repair the sealing surface with sealant, and pay attention to whether the sealant is completely matched with the pump body and sealing surface.

Treatment method for serious wear of inlet valve

To deal with the serious wear of the inlet valve, it is necessary to disassemble the pump. The serious wear of the inlet valve is due to the long service life, which causes damage to some components of the pump, leading to the failure of the pump to work normally. When it is found that the inlet valve is severely worn, it must be replaced. It is better to update the whole pump.

Shaft seal wear treatment method

The shaft seal wear treatment method is to disassemble the pump, replace the shaft seal, check and clean the pump internals, and ensure that the sealing material is completely matched with the pump shaft. After replacing the shaft seal, the pump parts must be reassembled and necessary tests must be carried out to ensure that the pump can work properly.

Treatment for damage of suction tube sensor

The damage treatment method of suction tube sensor is relatively simple, and usually only needs to replace the damaged sensor.

In the actual maintenance work, it is very important for the maintenance personnel of VIKING gear pump how to better maintain the equipment and troubleshoot. For different problems, we can adopt different methods, such as replacing the sealing material, replacing the whole or carrying out partial maintenance on the existing basis. Therefore, it is necessary to check and maintain the pump regularly, remove the fault in time, and ensure its long-term stable working state.
