The silicon tube used for peristaltic pump is made of imported high purity and high quality silica gel raw material and is manufactured by platinum curing process. The use of peristaltic pump ensures reliable flow and long service life.
The good peristaltic pump silicon rubber hose should have high purity, high wear resistance and high resistance to tear. In the production of the creeping pump hose, the wall thickness, diameter and material hardness of the hose must be strictly controlled, and a platinum vulcanization process is used. We recommend that users use regular peristaltic pump pipes, poor hoses can not guarantee the normal operation of the pump, or even damage the pump head.
The peristaltic pump hose must be tested and tested strictly before it comes out. The silicone hose specially made for the peristaltic pump is very different from that of the ordinary silicone tube. It is mainly manifested in the purity of the silica gel, the tearing resistance, the tensile property, the rebound performance, the tolerance control of the pump tube size and so on.
There are a lot of cheap silicon hose in the market. In fact, it is not a special peristaltic silicone tube. These silicone tubes are usually made of homemade silica materials. The purity of the raw materials and the proportion of impurities are very high, so the pipes are a little longer when they are placed and lose effect. The flow rate of the peristaltic pump is greatly influenced by the peristaltic pump tube, so the requirement for the inner diameter and wall thickness of the peristaltic pump is very high, and the size error is usually five percent millimeters. So ordinary silicon tube can only be used as a general purpose. The pump pipe used for peristaltic pump needs special use peristaltic pump hose.
The advantages of the peristaltic pump tube:
Excellent tear resistance, tensile properties, resilience and fatigue resistance.
The pump pipe is manufactured according to the strict tolerance requirements, ensuring that the size of the pump pipe meets the technological requirements.
The pump pipe has high transparency, smooth inner wall and high cleanliness
It can transport most organic solvents and tolerate acid and alkali within 30% concentration.
Anti aging and low permeability
A liquid with high viscosity can be conveyed.
High permittivity
It has three kinds of medical certification. It meets GMP and food grade requirements. It can be sterilized by ethylene oxide (ETO) or pot.
Select the hose steps:
1 determine the hose material suitable for the fluid to be conveyed
2 select the pump according to the required flow size and drive.
The factors that affect the performance of the hose: the hose recoverability determines the suction, the strength determines the pressure, the aperture determines the size of the flow, the wall thickness determines the efficiency of the pump and the pressure of the outlet.
Soaking test in type selection of pump tube material:
For the transportation of some liquids, especially for the delivery of special liquids such as organic solvents, a soaking test is usually required before selecting hose materials.
Test methods:
1 measure the weight and appearance of the hose.
2 dissolve the hoses in a sealed container with liquid to be transported for 48 hours.
3 remove the hose and clean the liquid on the surface of the dry hose.
4 test whether the weight, appearance and expansion, brittleness and elasticity of hose are changed.
5 if there is no change, it can be used.
Note: silica gel pipe can not be used to transport organic solvent, strong acid and strong alkali and other corrosive liquids, please call you to consult, we choose a suitable imported hose for you, the basic flow type peristaltic pump hose generally, the life of the hose will be affected by the following three aspects:
(1) the design of the material and hardness of the hose;
(2) the chemical properties and temperature of the fluid;
The use of pump head, pump speed and pressure, etc.
Friendly tips: when you are not working for a long time, you should lift the pressure block, relax the hose and extend the life of the hose.
