Peristaltic pumps, also known as constant flow pumps, are industrial pumps that can stably transmit liquids. They are mainly used for small and medium flow transmission. So what are the components of peristaltic pumps? What are their respective structures and characteristics?
1. The composition of the peristaltic pump
Peristaltic pumps are mainly composed of three parts: drive, pump head
, and hose. Among these three parts, the driver is used to connect the power supply, and the program is used to control the pump head. The pump head is used to install different hoses, and peristaltic pump hose
is used to transmit liquid, which is the only one in contact with liquid among the three parts.
2. Main features of peristaltic pump
Compared with other pumps, the peristaltic pump has a more prominent sealing performance. Because the entire transmission process uses the roller to squeeze the hose to generate pressure to absorb the liquid, so the entire transmission process will not contaminate the transmission liquid with other impurities, so there are often problems in the laboratory. The figure of a peristaltic pump.
3. Some deficiencies of peristaltic pumps
The operating principle of the peristaltic pump mainly relies on the pressure generated by squeezing the hose to inhale the liquid, so the pressure generated will naturally not be too high, so in the face of high viscosity and production environments that require high pressure, the peristaltic pump is not competent.
Secondly, the maximum flow rate of the peristaltic pump is only tens of liters per minute. If it is necessary to transmit hundreds of liters per minute or even higher, then the peristaltic pump cannot do it.
4. Maintenance of peristaltic pump
Compared with other types of pumps, the maintenance of peristaltic pumps is relatively simple, only the hose needs to be replaced regularly, and the driver and pump head can be kept clean in daily use.
5. Compatibility of peristaltic pumps
This is a major advantage of peristaltic pumps
. Although other pumps can also be matched with other equipment, peristaltic pumps are more flexible. For example, the pump head is adapted to a fermenter, or the pump head is matched with an industrial washing machine. The usability is higher.
