Failure Analysis and Quality Requirements of progressing cavity pump

When the progressing cavity pump is used to suck the liquid with low liquid level, occasionally there will be the phenomenon that the progressing cavity pump does not suck the liquid. However, the reason why the progressing cavity pump does not suck the liquid is not known because it does not understand the principle of the suction of the progressing cavity pump. In fact, the main reasons why the progressing cavity pump does not suck the liquid are as follows:To get more news about Progressive cavity pump part, you can visit brysonpump.com official website.

1. When the progressing cavity pump is used for the first time, there is no water in the progressing cavity pump or the medium conveyed by the tank, which results in the wear and tear of the rubber sleeve of the progressing cavity pump. This is one of the reasons why the progressing cavity pump does not suck liquid. The solution is that the liquid from the inlet tank of the pump should be put into the progressing cavity pump to keep the lubrication of the progressing cavity pump before use.

2. The suction height of the progressing cavity pump in use has exceeded the allowable suction height of the progressing cavity pump within 5 meters. 5 meters refers to a medium similar to sewage. If it is a liquid with high viscosity, such as mud, it is recommended to use a vertical progressing cavity pump or use various pneumatic diaphragm pumps to submerge into the liquid.

3. The voltage of the progressing cavity pump is 380V or above. After wiring, the motor of the progressing cavity pump is directly used without paying attention to checking whether the motor of the progressing cavity pump is reversed. At this time, we should replace any two of the three power lines.

4. The high viscosity of the conveying medium, such as lime milk, can only be used by backward-pouring progressing cavity pump. If it can not be backward-pouring, only vertical progressing cavity pump products can be selected.
