How to handle multi-stage pumps after long periods of non-use

How to deal with multi-stage pumps after a long period of time without turning? Consider improper storage leading to internal bearing jamming, or internal water is not drained in time to lead to impeller corrosion stuck, the corresponding treatment is also very simple, you can disassemble the impeller filter cover after using tools to disk can be, if the manual disk pump encountered resistance, with the help of rubber soft hammer knocking or pouring hot water to ease the blockage situation.

About multi-stage pump for a long time without turning how to deal with, in addition to the blockage problem, can also consider whether the motor in a long time storage process was damaged, such as storage environment humidity is too high, resulting in internal unit moisture, or the environment around the motor is too spoiled to cause a foreign body into the pump cavity, whether there is a broken motor cable and so on, in the exclusion of the motor itself, and then consider the multi-stage pump itself there are problems The problem itself will be considered after the motor itself has been excluded. From past experience in handling equipment, if the pump itself is a problem, the basic is the internal movement components stuck due to the need to disassemble the pump after the targeted treatment.

After understanding how to deal with multi-stage pumps for a long time without turning, pump personnel need to further understand how to avoid the emergence of such conditions, which only need to pay attention to the following operational matters can be.

1, for the use of multi-stage pump, before storage, pay attention to the internal liquid drainage, especially the transport of liquid is containing chemical properties of acid and alkaline liquid, it is necessary to promptly clean the pump cavity, to avoid condensation after the liquid stops flowing.

2, multi-stage pumps and pipeline pumps are used to transport the liquid does not contain particles of impurities, after the addition of wear-resistant machine seal can be adapted to part of the media with fine particles, but if the transport of the liquid contains more than the transport limit of the medium, over time will also form a blockage.

3, multi-stage pump internal and direct contact with the media part of the use of stainless steel, but stainless steel is not never rust, if the use of liquid is not drained, over time or rust, so even if the transport of clear water media, should also stop transporting all the liquid in the pump cavity.

The above content describes how to deal with multi-stage pumps for a long time without turning, it can be seen that the corresponding treatment is not complicated, if in the actual pump process encountered other difficult to solve the problem, welcome to directly consult zhaoquan screw pump industry.
