Operating Theory of Mixed-flow Pump
Saturday, 08 September 2018
When the prime mover driven impeller rotation, the centrifugal force of the liquid but also the role of both the axial thrust, centrifugal and axial flow pump is integrated, diagonal liquid outflow impeller. Therefore, it is between centrifugal pump and axial pump.Its head is higher than the axial flow pump. The structure of mixed-flow pump is between

Matters need attention when pump is in operation
Thursday, 30 August 2018
Pump is activated when the electric pump is running, the rotation should be smooth and free of vibration and abnormal noise, observe whether significant fluctuations around the motor running current and line voltage start. After the motor main circuit is energized, the motor does not rotate if found, should be shut down immediately to prevent

How to Maintain Self-priming Sewage Pump
Wednesday, 22 August 2018
1) Check if the self-priming pump tubing and junction is loose. Turn the pump by hand or tool, then to observe if the sewage pump is flexible. 2) Try to control the inner self-priming pump flow and head on the plate indicated range to ensure self-priming pump at maximum efficiency point operation. Transfer to achieve

What situations should stop using the submersible pump immediately?
Wednesday, 04 July 2018
The choice of the submersible pump before use is very important. Consider the actual situation of the water source, working time, pumping volume, etc., and comprehensively determine the model of the submersible pump selected. Just like the requirements of the environment, it is necessary to have a safe and reliable power supply, the drop of

Submersible pump: pump inspection after assembly
Thursday, 30 November 2017
After assembling the hub of the pump on the shaft, the verticality and concentricity of the hub and the shaft should be carefully checked. Generally, two dial indicators are arranged on the end surface and the outer circumference of the hub. When the disk drive rotates the shaft, the value of the full run-up (including

Startup methods of pump
Thursday, 09 November 2017
The pump transmits the mechanical energy or other external energy of the prime mover to the liquid to increase the liquid energy, which is mainly used to transport the liquid including water, oil and acid-base liquid. Pumps are divided into different categories according to different conditions, and each pump has its own unique method of
