Screw pump It has the characteristics of adsorption, large overturning, liquid solid particles, liquid solid particles, etc. It can transport liquid particles in sewage treatment plants such as water, sludge, condensate, etc. Screw pumps in China should be selected according to the standards of socio-economic development and efficient feasibility analysis. If the selection of model planning is not considered, the subsequent application, handling scheme and detection will remain unchanged. Therefore, according to the main necessity of manufacturing, selecting efficient and stable screw pumps can ensure the smooth development of manufacturing and reduce maintenance costs.

1、 Select screw pump transmission ratio

Although the fast screw pump can improve the flow and pump impeller, the power is further improved to quickly accelerate the friction resistance between the motor and the motor stator. However, the screw pump must fail early. The fixed motor of the fast rotating pump has short rated power and is easy to damage, reducing the application of the screw pump.

According to the speed ratio between the lowering deceleration mechanism and the non speed regulating mechanism, the speed ratio can be maintained in a more reasonable area of less than 300 revolutions per minute.

2、 Mass of screw pump

At present, there are many kinds of screw pumps in the market. The imported screw pump scheme is reasonably planned, and the raw materials are good, but the price is high, the service level is not high, the price of parts is high, the order information time is long, and the order information time is long, which will endanger the normal operation of everything.

3、 Ensure that sand does not enter the pump body

Because the rubber material motor rotor in the wet test sludge is damaged, it is particularly important to ensure that the dirt does not enter the pump inner wall. Many sewage treatment stations have updated and transformed the crusher equipment in front of the pump, installed a crusher or filter equipment, and blocked the stains into the screw pump, which should be eliminated immediately to prevent blocking.

4、 Prevent laser cutting raw materials

smash IMO screw pump It cannot be used for laser cutting raw materials. Once this happens, the fixed splint of the rubber material motor will be dry and rubbed, resulting in instant high temperature scalding. Therefore, the crusher equipment is intact, and the sliding hill is one of the necessary conditions for the normal operation of the screw pump, so some screw pumps also need to be installed on the automatic switching machine.

5、 Stable working pressure of adhering to access conditions

The screw pump is a volume rotary pump. When the resistance is imported, the working pressure will gradually rise, and then exceed the preset pressure. At this moment, the motor load will greatly increase, and the load of the mechanical parts of the transmission equipment will also exceed the plan value. In order to prevent the screw pump from being damaged, the screw pump channel is generally equipped with a bypass valve regulating valve to ensure that the inlet working pressure is stable and the pump operates normally.
