Peristaltic pump advantages and limitations

The peristaltic pump advantages: delivery of media and pump body is not in contact, it is conducive to the delivery of some metal corrosive media, such as: various acids, alkaline solution, or some chloride ion salt solution. Cleaning, disassembling simple and quick. Because the medium only flows in the hose, the cleaning is only for the hose, and the installation and removal of the peristaltic pump hose are relatively simple. Just click the motor to complete the installation and removal. Can control the speed and flow. The motor used for peristaltic pump after deceleration of the reducer, the speed is not high, the general maximum speed of not more than 165 rev / min, and the selection of the motor can be used manual speed control and frequency control to better control flow. Because the press rolls work by squeezing the hose tangentially and with a low speed, it has unique advantages in transporting some more sensitive and easily damaged media. Durable - suitable for a variety of industrial or laboratory conditions. Very good self-priming function - non-siphon, can dry and self-absorption. Limitations of Peristaltic Pumps: Pressure Limits: With flexible tubing, the pressure under pressure will be limited. The pump produces a pulsed flow during operation. The solution is to use a pulse suppressor. The pulse suppressor is a simple positioning vessel that operates on the principle that air is more compressible than liquid and that pulses flow into the container. The gas bag on the liquid sinks to absorb the pulse and thus smooth out the pulse suppression Device.

Automotive air conditioning refrigerant is also called refrigerant refrigerant car car,
commonly known as snow, ice, divided into environmental protection (134a) and non environmental (R12 few models use). The general need to fill the car refrigerant in the summer comes, the car of refrigerant should pay attention to the following two questions: one is the refrigerant not interchangeable the problem, another is the vacuum problem. Automotive air conditioning refrigerant mainly has two kinds, one is R12, another is 134a (HFC 134a R12), a long history and widespread use, but the gas containing chlorine molecules will destroy the ozone layer in the atmosphere and cause the greenhouse effect, so the number of years ago, delegates from around the world gathered in Montreal signed the protocol required in recent years to stop the production and use of CFCs products, of which R12.134a is bear the brunt of 90s began to use varieties, because no chlorine molecules without damage to the ozone layer of Car air-conditioning system changes less, and now a lot of new domestic and foreign air-conditioning systems are using 134a refrigerant
