The basic structure of pipeline pump is composed of six parts: impeller, pipeline pump body, pump shaft, bearing, sealing ring and stuffing box. 1. Impeller is the core part of centrifugal pump. It...
Centrifugal pump is a widely used water pump product at present. It is widely used in oil and gas, petrochemical, steel, electric power, food and beverage, chemical industry, pharmaceutical and wat...
Deep well submersible pump is a water lifting machine with direct connection of motor and water pump. It has the advantages of simple structure, high unit efficiency, low noise, safe and reliable o...
Fault 1: Fault phenomenon: no water, little water or intermittent water. Cause: A. motor reverse rotation; b. The motor is not started; c. The dynamic water level is lower than the suction inlet; d...
First, look at the difference between the current of the water pump running at this time and the current of normal operation. 1. When it is smaller than the normal operation (basically 2 \ 3 of the...
Deep well pump and submersible sewage pump are the same pump products we often use at present. They are different. Today I'll explain their differences for you. Deep well pump is a kind of pump...
When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to the structural limitations of mud...
In the water pump industry, there are many kinds of pumps. Chemical centrifugal pump is a common pump type. It is widely used in chemical production and sewage discharge. Bearing is the main rotati...
At present, the efficiency of most models of centrifugal pumps is generally about 70-80%, and the efficiency of a few large flow models is about 90%. The main reason affecting its efficiency is the...
1. Leakage during static test of rotor pump installation After the installation and commissioning of mechanical seals, it is necessary to conduct relevant tests on the pump to observe the leakage o...
