Comparison of corrosion-resistant peristaltic pumps in replacing traditional corrosion-resistant pumps
Wear analysis of corrosive media transported by ordinary pumps:
1. Ordinary corrosion-resistant pumps are subject to both mechanical wear and corrosive media erosion. In the production process applied to the pump, there are many conveying environments and conveying media which are highly corrosive, and corrosive materials have special requirements for the pump. The common pump type uses the material to directly contact the medium when solving the medium. The way, while the pump is subjected to corrosive tests of corrosive media during operation, it is also subject to mechanical wear during pump operation. In the case of the addition of these two types of wear, the life of the pump will decrease and the failure rate will increase significantly.
2. Corrosive media transport is often accompanied by high temperatures, high pressures or impurities, which will further affect the life of the pump. Various chemicals and organic solvents are often accompanied by an increase in temperature during the transfer process, and many media have high viscosity and large specific gravity due to various processes. These phenomena have a severe test for the pump.
3. The high speed and high shear of the traditional pump in use will also accelerate the self-damage of the pump.
Problems with ordinary mechanical pumps,
1. There is high shear. Some chemical media require a smooth flow during transport, and it is required that no damage to the media or impact can be caused.
2, need to fill the water, or the suction is very low. Without self-priming, it will affect the convenience of production.
3. The liquid is retained in the pump, which affects the cleanliness and process. Inconvenient to clean.
4. Maintenance and replacement of consumable parts is complicated.
The above part is based on my experience in pump application for many years. There must be unfinished and biased aspects. For my colleagues only, welcome to correct and improve.
The PPS type peristaltic pump developed by Chongqing Jieheng Peristaltic Pump Co., Ltd. uses PPS polymer material for the pump head casing. The inner material contact pipe fitting is a high-performance engineering plastic hose. (This floppy disk can be made of rubber of different materials. Made of plastic, it can withstand various organic solvents such as acid and alkali, oils, lipids, and can withstand high temperature test. It can solve the problem of chemical transportation. And its long service life, hose replacement is convenient. It can completely solve various problems existing in common corrosion-resistant pump products, thereby reducing production and engineering costs and improving system stability.
