The working principle of centrifugal pump
Monday, 14 October 2019
The working principle of centrifugal pump is that when pump is filled with water, centrifugal force generated by the rotation of the impeller, the impeller channel water thrown to the periphery by centrifugal force flows into the pump housing, thus reducing the pressure on the center of the impeller, the pressure is lower than the

Volume loss of centrifugal Pump
Thursday, 25 May 2017
Volume loss of centrifugal pump including seal ring leakage loss, balancing mechanism leakage loss and interstage leakage loss. This article describes the seal ring leakage loss. In the entrance of the impeller is a seal ring, when the pump works, because the sealing ring on both sides with pressure difference between the side of the approximately impeller outlet pressure side

Do you know the history of pump?
Tuesday, 08 November 2016
The emergence of pumps for human life and production are very important. There are various water lifting devices in ancient times, such as the Egyptian chain pump (before the 17th century), China’s orange (before the 17th century), the pulley (before the 11th century), waterwheel (AD 1 century), and the 3rd century BC Ancient Greece Archimedes

Balancing mechanism leakage loss
Tuesday, 23 August 2016
In many centrifugal pumps, it do not balance the axial thrust mechanism: such as balancing holes, balance pipe, balance disc and the like. Since both sides of the balance mechanism there is a pressure difference, which is also a part of the liquid leakage from a high pressure area to the low pressure area. About 5%

Hydraulic loss of centrifugal pump
Monday, 15 August 2016
Hydraulic loss of centrifugal pump including shock loss, whirlpool loss and frictional loss. First, the shock loss Each pump has its own design flow, when consumed in the design flow conditions at work, the entrance is down stream into the impeller blades, and therefore does not react with the blade hit the same outlet flow nor the occurrence
