Laboratory peristaltic pump silicone tube must be tested in all aspects before use, otherwise it will damage the service life of the silicone tube. So, what does the test involve? The following Peristaltic pump detailed analysis of the test content.

Laboratory peristaltic pump silicone tube must be tested in all aspects before use, otherwise it will damage the service life of the silicone tube. So, what does the test involve? The following Peristaltic pump detailed analysis of the test content.

1. laboratory peristaltic pump silicone tube size test, should first look at the appearance, pay attention to whether there are bubbles, impurities and black spots on the wall. Once it exists, it will affect its service life. Secondly, the accuracy of the size will directly affect the flow of the pump. The flow rate is mainly determined by the inner diameter of the hose. The larger the inner diameter, the greater the flow rate. The outside diameter or wall thickness will affect the service life of the hose. If the wall thickness exceeds the conventional tolerance, the hose will become rigid, which will affect the operation of the pump body.

2. in order to test the wear resistance, fatigue resistance and resilience of the silicone tube of the laboratory peristaltic pump, it is recommended to use the limit test method, adjust the rotational speed of the laboratory peristaltic pump to large speed, transport weakly corrosive fluid, observe the flow change of the laboratory peristaltic pump every day, continuously start the pump, the hose is not damaged, the flow change is not obvious, It shows that the elasticity, fatigue resistance and wear resistance of the hose are good.

3. test laboratory peristaltic pump silicone tube aging and corrosion resistance. Take a section of sample tube, record its weight, inner and outer diameter, length and other parameters, soak the hose in a glass beaker, take out the hose 72 hours later, rinse and dry with water, re-measure its weight, inner and outer diameter, length and observe their changes; By the way, check whether the hose is soft, brittle, white, cracking, etc., if there is a change, indicating that the hose is affected by the chemical effects of the liquid, indicating that the pump pipe aging, poor corrosion resistance. Each candidate pump tube sample should be put into the actual environmental conditions of the plant for test run, and the test results are closely observed. If the pump tube does not appear discoloration, expansion, cracking, fluidity loss or other deterioration after commissioning, it is proved that the pump tube has good chemical stability.

4. according to the actual application field of laboratory peristaltic pump to determine the phase certification required for laboratory peristaltic pump silicone hose, such as FDA, lfgb, USP level 6. etc.

Laboratory peristaltic pump silicone tube using imported silica gel raw materials, vulcanized by platinum, strictly standardized production. Equipped with laboratory peristaltic pump to ensure accurate and reliable flow and stable performance.

Pump pipes are strictly tested and inspected before leaving the factory. These customized silicone tubes for laboratory peristaltic pumps are very different from ordinary silicone tubes, mainly in tear resistance, tensile performance, resilience and tolerance control of pump tube size.

Changzhou PreFluid Technology Co., Ltd. as a professional manufacturer of peristaltic pumps, has been providing comprehensive solutions for various fields of fluid, through more than 10 years of experience accumulation, has enough R & D and production strength to meet customers for products value for money, low cost, high reliability, simple maintenance, quick after-sales response needs. Minimizing production and product costs and optimizing the production process for our customers is the ultimate goal of our peristaltic pump solutions for all our customers.
