Horizontal centrifugal pump failure is inevitable, according to different circumstances, we deal with the problem in different ways, and when the equipment in the process of operation, if the following situations, must stop inspection processing.
Horizontal centrifugal pump failure is inevitable, according to different circumstances, we deal with the problem in different ways, and when the equipment in the process of operation, if the following situations, must stop inspection processing.
1. The double suction pump is evacuated or cavitation occurs, the pump pressure changes abnormally, and the pump body is hot;
2. The pump body stings water, the pump rotor shifts or the water injection station system leaks. Pipeline rupture;
3, bearing water, lubricating oil serious discoloration or high water content;
4. The pressure of the water injection pipeline is high, the displacement of the double suction pump is very small or the water is not discharged, and the efficiency is extremely low;
5. The unit has abnormal noise or severe vibration;
6. Personal accident caused by double suction pump operation;
7, the motor current suddenly large fluctuations;
8, machine pump temperature due to more than the specified value and smoke or burnt smell;
In the above cases, it is necessary to stop the machine for inspection, find the problem and solve the problem before starting up again. Here is a point, many customers for double suction pump is not particularly understanding, buy back directly thrown in the sewage pit began to work, and did not do a little protective measures, this is wrong, the life of the pump will be fatal damage. Therefore, it is suggested that the customer should be equipped with a control box after buying it back, so that if there is a problem, the control box will play a specific protective role.
