Screw Pump Application Characteristics and Selection
Screw pumps, also known as screw pumps, are non-clog pumps, which are mainly used in industrial wastewater treatment and transportation occasions, and are widely used in the fields of petrochemical industry, urban sewage treatment and industrial wastewater treatment.
1. Application characteristics of screw pumps
The screw pump is a new type of integration structure which combines the screw type lift structure and volumetric pump structure. It has strong self-priming ability and no need for other self-priming devices, and its lift height can reach 5-6 meters. The permanent medium and large particles in the pump are not easy to block, the operation and maintenance are almost trouble-free, it is wise to choose if the sewage contains a large number of solids and fibers. In addition, the screw pump is highly efficient, energy-saving, low noise and reliable operation.
2. Selection of screw pump
When selecting a screw pump, the following points should be noted:
(1) Use conditions: The environment of water suction, the conditions of medium, temperature and pressure must be clear to select the right pump;
(2) Flow rate and amount of discharge: According to the flow rate required by the system, the actual flow rate and lift capacity of the screw pump should be determined;
(3) Suction height: It is necessary to determine the suction height according to the actual situation, generally depending on the characteristics of the pump;
(4) Efficient level: According to the required power, select the most suitable efficiency of the pump.
In conclusion, screw pumps are becoming increasingly popular in industries due to their many advantages such as strong self-priming ability, large amount of liquid delivery, no need for other self-priming devices, and so on. When selecting a screw pump, users should pay attention to the use conditions, flow rate and discharge amount, suction height, and efficient level.
