2, the inner diameter of the hose size also plays a decisive role. Under the premise of using a special hose, whether the inner diameter is too thick or too thin, the thickness of the inner diameter also determines the amount of fluid pumped. If operating at high temperatures, the flow rate of the peristaltic pump will also be affected by changes in the elasticity of the hose. So before use to confirm whether the hose is brittle, hard, loss of elasticity, discoloration, breakage and other phenomena, if necessary, please replace the hose in a timely manner.
3, the pump speed is also one of the effects. The greater its speed, the greater the flow rate will be. Rotation speed refers to the peristaltic pump motor running speed, the motor will generally be with the temperature of the elevation of the change, peristaltic pump flow will be different.
4, the size of the suction range directly determines the size of the air pressure difference, which in turn has a greater impact on the amount of hose rebound and rebound speed. In the use of peristaltic pumps, if you need the stability of the flow rate, you should avoid large fluctuations in the suction range at the liquid level, because this fluctuation will directly affect the size of the flow rate.

Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable delivery, self-priming ability, reversible, and able to transport solid particles of liquid, etc., in the wastewater treatment plant, the screw pumps are widely used in the transfer of water, wet sludge and flocculant liquid.
2, screw pumps due to the structure and working characteristics, can transport high solid content of the media, flow uniformity, pressure stability, low speed is more obvious, due to good variable adjustability, and thus can be a pump for multiple purposes, transporting different viscosity of the media.
3, the installation position of the screw pump can be tilted arbitrarily, suitable for conveying sensitive goods and goods susceptible to damage by centrifugal force and so on.
Knowledge point three,Screw pump working characteristics
Screw pumps mainly have the following characteristics: simple structure, the use of safe and reliable, easy to use and maintain, the liquid continues to be an average, stable pressure, murmur and vibration of the small, with the ability of self-absorption, but the processing of the screw is more troublesome.
Knowledge point four,What is the three screw pump
Screw pump is a rotary displacement pump, according to the number of screws, can be divided into single-screw, twin-screw, triple-screw and multi-screw pumps, the three-screw pumps, that is, the three screw pump. Three screw pump, is a three screw screw pump, including an inserted in the pump cylinder in the active screw and its engagement of the two slave screw, the three mutually meshing screw, in the pump cylinder according to each lead to form a sealing cavity, resulting in the suction and discharge between the mouth of the seal.
Knowledge point five,peristaltic pump uses what
Peristaltic pumps of any of the use of the scene is to deal with fluid (can be any liquid with fluidity, can also be a mixture of solid-liquid), peristaltic pumps is the main role of the transfer. Peristaltic pump conveying accuracy can reach up to ± 0.5%, so it can meet the needs of quantitative conveying, but also can meet the needs of quantitative distribution.
From the level of product function, the use of peristaltic pumps is mainly: quantitative or metered delivery, quantitative or metered distribution. So where there is quantitative conveying and distribution needs of the application scenarios, can choose peristaltic pump to meet the application requirements.
