Platinum cured silicone hose has a wide range of application
The special silicone hose for peristaltic pump is a new type of silicone hose, which is widely used in medicine, food, chemical industry and other industries. It transmits some sensitive, viscous, highly corrosive, abrasive, high-purity requirements and some granular materials.
When choosing a peristaltic pump, whether it is an industrial peristaltic pump, a laboratory peristaltic pump or a liquid-liquid transmission peristaltic pump, it determines the working efficiency or transmission accuracy of the peristaltic pump, and also determines that the transmission accuracy of the peristaltic pump requires a good peristaltic pump body. , Peristaltic pump head and hose.
Among them, the peristaltic pump hose is the main working part of the peristaltic pump. Its performance directly affects the accuracy and stability of the peristaltic pump flow. There are many factors that affect the service life of the peristaltic pump hose, such as the running speed of the pump head and the softness. The material of the pipe, the gap between the pump head roller and the arc, etc.
First of all, fatigue damage is the main performance of hose fracture, and the operating speed of the pump head needs to be adjusted. Industry experts believe that when choosing a peristaltic pump, you should try to choose a pump head with a large flow rate, which can also run at a lower speed, thereby extending the life of the hose.
Secondly, the choice of material plays an important role in the overall performance of the peristaltic pump hose. Domestic hoses are generally food-grade silicone hoses, and their calibration life is generally 200 hours (uninterrupted operation at 600 rpm), but under the same conditions, imported hoses can have a long life of more than 1200 hours.
In addition, the size of the pressure pipe gap and the uniformity of the pressure pipe gap will also affect the service life of the peristaltic pump hose. For example, whether the arc curve is uniform, the machining error of the roller and the wheel, the assembly error of the roller center and the arc center, etc. If the gap of the pressure pipe is not uniform, in order to ensure the air tightness of the pump head, the position of the lower pressure will not leak, so that the rest of the position will be overpressured (the gap is less than the normal value), which will reduce the part of the hose life.
With the development of the market, taking the particularity of the medium as an example, the transportation of corrosive medium is often accompanied by high temperature, high pressure or impurities, which will further affect the service life of the peristaltic pump hose. The emergence of corrosion-resistant peristaltic pumps makes up for the traditional peristaltic Defects of the pump.
