About the structure of the multi-stage pump

In daily work, the application of stainless steel multistage pump can be said to be more widely. Multistage pump is a kind of more special centrifugal pump, it is according to the design of segment and middle in and out of the water. The two parts by stick together, to form the multi-stage pump. More than a few water water pump output pressure is bigger, he mainly depend on the rotation of the impeller, the rotation of the impeller is used to drive water, making water through centrifugal movement back inside the pump body, using the centrifugal force of water for daily work. In centrifugal movement of water, if the air density between the water reach the work scope of multistage water pump, air is pulled out. More than a few pump is a special kind of centrifugal pump, is that it can transform your pump body volume, it mainly through the air in the pump cavity change. Below let us have a detailed understanding of the structure of vertical multistage pump.

is a major component of multistage pump, including water pipe in the pipe and the water pipe, also including some of the positive and negative impeller and drainage of the pressure-relief devices, also includes filter tube and bearing, etc. Multistage pump rotor is installed on the pump body, impeller and drainage of pressure-relief devices as well as the impeller bearing. The drive end of the multistage pump adopt the circular bearing, at the end of a few more water pump adopts the cylindrical bearing and round ball bearing combination. Multistage pump is the most important part of the impeller part, because the impeller part is the core of the multistage pump work, the multistage pump is depend on the rotation of the impeller to work, it needs the impeller continued to keep high speed operation, to drive the transmission of the liquid. If you want to keep the impeller high-speed stable operation, must use good blade and maintain the stability of current, especially when selecting a blade, must choose those who seem more smooth blade, and corrosion of liquid so that you can reduce the friction. In addition to the part of the multistage impeller pump bearing, is also a very important part of the multistage pump bearings mainly play a supporting role of pump body parts, bearing atmosphere, rolling and sliding two types, a rolling bearing usually use butter as a lubricant, and when using the butter as a lubricant, usage not too much, otherwise it will affect the engine heat dissipation, multi-stage pump pump body fever, if the amount of use of lubricant is too little, can increase for the friction between bearing, reduce the service life of multi-stage pump.

J&T INDUSTRY CO.,LTD. thinks that that firms can avoid the artificial choice between quantitative and qualitative risk management, allowing both to play important roles in surfacing and assessing risks.
Energetic, optimistic entrepreneurs often tend to believe that sales growth will take care of everything, that J&T INDUSTRY CO.,LTD. will be able to fund our own growth by generating profits.
Digging into our roots and acknowledging out heritage can be fruitful on both a high-quality and professional level of submersible pump.
