How to increase the displacement of a progressive cavity pump

Screw pump in the normal drive flow is stable without pulsation, with a high processing efficiency, but if the unexpected working conditions lead to some kind of failure, it will affect the flow parameters, recently there are also customers consulting screw pump displacement on how to do, in this regard, the need to identify the causes of abnormal flow according to the actual working conditions, and then the corresponding solutions, see below for details.

On the screw pump displacement on how to do, in the pump industry has a set of standard solutions, can cope with most of the working conditions, it is recommended to arrange professional and technical personnel to deal with, to prevent improper operation to expand the damage.

A, the installation position does not meet the standard

Installation is a rather important part of the use of all pump products, according to the pump type and size structure, the pump has different installation standards, one of the relatively important is the choice of installation location, to ensure that the pump motor has enough space, can play a good heat dissipation, but also to facilitate future maintenance, but also not too high, to avoid the lack of self-priming force and lead to the displacement on not go, so if the pump is used for the first time on the appearance of Displacement problems, it is recommended to check whether the installation is up to standard first.

B, the motor power supply is abnormal

Screw pump is a motor-driven pump, driven by the motor internal stator and rotor mesh to move the material, if the motor due to moisture, overload, overflow, into foreign objects and other reasons leading to a decline in quality, directly affecting the speed will appear on the displacement of the situation. It is recommended to check the current of the motor, check whether the speed is up to standard when running, whether the steering is wrong, if necessary, replace the new motor, pay attention to the use of power matching the original factory matching motor.

C, the pump cavity blockage caused by

Single screw pump is specialised in handling complex media, such as high viscosity oil or mud water with high solids content, if you do not pay attention to cleaning the pump cavity after each completed transport work, it will lead to media solidification in the pump cavity resulting in blockage, thereby reducing the operating displacement. The correct approach is to use a solvent to unclog the pump chamber, add a strainer to the pump inlet and clean it well after each use to ensure the flow path is clear.

Through the above-mentioned causes and treatment can effectively solve the user screw pump displacement on how to do the problem, if in the process of using the pump encountered other difficult to solve the problem, can be directly to zhaoquan pump industry to seek professional technical support.
