Factory directly sell peristaltic hose pump belongs to the category of peristaltic pumps. A peristaltic pump is a type of rotary positive displacement pump. They are named because they function like the gastrointestinal tract to transport gas, solid and liquid three-phase media. There is no strict distinction between mud-fed small hose pumps for slurry grout and peristaltic pumps. Generally speaking, peristaltic pumps refer to small flow rates (ml / min) and low outlet pressures (3 kg / cm2 or less) and are mainly used in the fields of health and laboratory measurements. Small hose pumps for slurry grout refer to high flow rates (up to 80 m / h) and high output pressures (up to 16 kg / cm2) and are primarily used for high flow transmission and industrial measurements.
Factory directly sell peristaltic hose pump first evaluate their ability to carry highly abrasive media. There are no valves or seals. Only the internal cavity of the rubber hose comes into contact with the medium. The rotor of the factory directly sell peristaltic pump is completely independent of the medium. In addition, hose pumps for slurry grout have many unique features. No other pump has as good a self-priming capacity as a hose pump for slurry pumps that can generate an almost complete vacuum for sucking liquids. The factory directly sell peristaltic hose pump also has the advantage of carrying highly viscous shear sensitive media. The fixed capacity per revolution is a natural weighing pump that has nothing to do with the outlet pressure.
How to solve these problems? Then answer each question.
1. The rupture of the throttle pipe is due to excessive pressure at the pump outlet. It must be the entire haul pipeline or the haul front end. If the outlet pressure of the small hose pump for slurry injection still exceeds the rated pressure, it is necessary to adjust the gap between the squeeze wheels to increase the gap between the squeeze wheels and reduce the working pressure.
2. Insufficient flow rate means that the discharge flow rate of the small hose pump for slurry grout is less than the work flow rate requirement. This is because the gap between the squeeze wheels is rather large, but the amount of interference when the pipe is squeezed during work is small, and the flow rate at the outlet does not decrease because only the backflow of the conveyed fluid is present. If necessary, the gap between the squeeze wheels should be adjusted and reduced.
3. The pressure at the outlet of the factory directly sell peristaltic hose pump cannot reach the pressure required for the work. At this time, the more material that returns directly from the squeeze tube, the more the squeeze wheel gap needs to be adjusted to avoid meeting the work requirements. If it is smaller, increase the squeeze interference of the squeeze tube to increase the pressure.
4. If the squeeze tube wears faster than normal, there is a possibility of abnormal wear. At this time, first lubricate the squeeze tube, whether to apply lubricating silicone grease regularly, whether the squeeze wheel and recovery wheel are rotating normally, whether the squeeze wheel or recovery wheel is stuck, or whether it can not rotate normally. You need to confirm. It also accelerates the wear of the squeeze tube.
