Pressure of your peristaltic pump hose
High pressure hose expands the usage of peristaltic pump. For example, filter. The pressure resource can be different for a fluid transfer system. When push fluid to a filter or valve, there will be back pressure. When choose the pipe, you should make sure all the pressure resources. Besides, you should already get the test value of general pressure. Then make sure the work pressure not beyond the hose pressure. Once the pressure is over high, the hose will swell. Besides, it causes bad connection with pump head. Then causes over wear and failure.
While when system pressure much larger than the hose, it will burst. Then spray the fluid out and cause serious accident. Thus when choose a peristaltic hose, make sure the work pressure is within it that supplier suggest.
But what to do when system pressure is over high?
On such occasion, you can install a pressure release valve to avoid over pressure. The function of valve is: when pressure beyond the preset, the valve will release the air out. Thus the pressure could reduce to the safe level. You can also use a complex switch. When pressure reach the preset, it will shut down the machine or give an alarm. Both of them are effective.
The work temperature is another factor you should concern. Some materials can bear high and low temperature. For example, silicone hose. While some hoses can just bear in small range. Thus before purchase the hose, confirm the temperature range in system. Then guarantee the peristaltic hose work within them safely. Besides, temperature affects the chemical and pressure resistance. When temperature grows, the pressure resistance will reduce.
