Peristaltic pump is a new type of industrial pump, widely used in pharmaceutical, food, chemical and other industries, conveying some sensitive, viscous, corrosive, with grinding, high purity requirements, and containing a certain granular material medium.
Several factors affecting the operation of peristaltic pump:
1, liquid properties: can not react with peristaltic pump tube;
2, temperature: will affect the motor, the motor will generally have a certain impact with the increase of temperature;
3, pressure: the pressure is too large, sometimes the liquid can not be transmitted;
4, the viscosity of the liquid: too much viscosity will make the roller idling;
5, hose: the use of a long time will occur wear.
Laboratory peristaltic pump how to buy:
1. Number of channels
The general peristaltic pump is only equipped with a pump head, then there are two pump heads, you can choose according to your own needs, there are two, there are four, but note that as long as it does not exceed the maximum torque of the drive is OK.
2. Control accuracy
As an instrument for liquid delivery, there are certain requirements for the control accuracy of peristaltic pump in some areas, and the accuracy control of flow is directly related to the motor of the pump, so we need to look at the motor when choosing, the more accurate the speed of the peristaltic pump driver stepper motor, the more control of flow.
Third, control mode
Now the peristaltic pump operation can be said to be very simple, the front of the pump has a display of various data will be displayed on it, and the peristaltic pump also realizes the control through some equipment, there are many different controls, so we should choose according to their own needs to choose their own.
