IMO screw pump Is a common centrifugal pump, widely used in shipbuilding, chemical, petroleum and pharmaceutical industries. However, in the process of use, sometimes it can not be started. Next, we will analyze IMO from several aspects Screw pump The reason for failure to start, and propose corresponding solutions.

1、 Power problems

A common reason for failing to start IMO screw pump is power problem. First, check whether the power supply is well connected and whether the wires are broken or short circuited. Secondly, check whether the motor is restricted by the protection controller and try to remove the restriction. If none of the above methods can solve the problem, you need to use a voltmeter or multimeter to check whether the power supply can output voltage and current normally.

2、 Mechanical problems of the pump

Another reason why IMO screw pump cannot be started is that the mechanical parts of the pump have problems. First, check the pump shaft for rotation obstacles, such as coins, sand and other impurities. Secondly, check whether the pump seals and mechanical seals are worn, causing leakage. You can also check whether the pump belt drive is correct and whether the belt tension is appropriate.

3、 Control system problems

If there is a problem with the control system, the IMO screw pump may not start. IMO agent First, check whether the controller is configured correctly and whether the parameters meet the requirements. Secondly, check whether there is a line fault, such as whether the controller is correctly connected to the pump motor, limit switch, etc. If the control system has serious problems, it is recommended to contact professional technicians for maintenance and replacement.

IV Pipes are not connected correctly

If the pipe connection of IMO screw pump is incorrect, the water flow may not flow smoothly. First, check whether the pipeline connection is correct, including pipeline straightness, elbow angle, pipeline material, size, etc. Secondly, check whether there are blocked foreign matters on the pipeline. If the above aspects are checked correctly, it is necessary to check whether there are leakage points, including connection points, seals and other positions.

5、 Motor stall

The stall of IMO screw pump motor is also a common problem that causes failure to start. first, Viking Check whether the motor is overheated or damaged due to excessive load. Secondly, check whether the motor rotor has grounding, broken winding and other faults. Finally, check whether the dust removal and heat dissipation of the motor are normal. If the motor problem is serious, it is recommended to repair or replace the motor first, and then further check the water pump problem.

To sum up, IMO screw pump cannot be started for many reasons, including power problems, pump mechanical problems, control system problems, pipe connection problems, motor stall, etc. When solving problems, it is necessary to judge according to the specific situation and take corresponding solutions. In addition, we suggest that regular maintenance should be carried out during normal use, and some minor faults should be handled in a timely manner, so as to avoid turning the big issues into small ones.
