Peristaltic pump tube as one of the three components of the pump system, is a common consumable, since it is a consumable that the pump tube is always subjected to some wear, but sometimes there will be some unexpected situations, resulting in increased hose wear, or direct damage, today, PRy fluid will explain the reasons for this problem.

First, the peristaltic pump tube burst

Phenomenon: Observe the burst part of the pump pipe, showing a series of cracks, the mouth is relatively smooth, like being used by sharp objects across, generally appear in the pump head.

Reason: This is usually because the runner flange of the pump head is scratched, because the peristaltic pump hose in the pump head is too long, resulting in the pump head in operation, the edge of the rotor contact the hose, in the case of constant friction, will increase the loss of the pump tube, generally in about ten minutes will burst phenomenon, after the burst will produce a lot of pump tube residue.

The solution:

1. Straighten the hose when installing the stuck peristaltic pump tube so that the hose fits the rotor in the pump head.

2. Clamp the hose with the pump head, mainly to prevent the pump from loosening during operation.

Two, the peristaltic pump tube is completely flattened

Phenomenon: The pump tube is flattened, unable to rebound and the tube wall becomes thin, mainly reflected in the surface wear.

Reason: It is generally because there are impurities or sticky hard substances on the rotor, or there are residual substances on the pressing block and the temperature is too high.

The solution:

1, since it is due to the friction of the block or rotor resulting in the loss of the pump tube, both can be cleaned before use to ensure smoothness.

2, high temperature is divided into two cases, one is the temperature of the working environment, the other is the speed is too high. If the working environment, you need to consider whether you need to replace the high temperature resistant pipe, the speed is too high, then consider reducing the speed.

Three, the peristaltic pump tube becomes brittle and hard

Phenomenon: The pump tube becomes brittle, hard, elastic and swelling.

Reason: The liquid needs to be checked to see if it has characteristics such as corrosion and what material will react with it.

Solution: For different liquids, the option of different peristaltic pump tube, can not be generalized.
