Everything About Progressive Cavity Pump

The name progressive Cavity pump refers to all pumps where the water is displaced either by a plunger, piston, bucket and so forth. The progressive cavity pump and centrifugal pump are two unique concepts. They are separately name following the structure and function. The functioning principle of the progressive cavity pump is to earn the water circulate. By way of instance, the hot water from the heat supply pipeline is circulated via this pump. This kind of pump is made up of a closed cylinder in which a piston moves to and fro with a connecting rod. The connecting rod is hinged using a wheel that is rotated by a motor. Throughout the suction stroke, the suction valve is opened and delivery valve stays closed and water enters the cylinder. Throughout the delivery stroke, the delivery valve is opened and the suction valve stays closed and the water is forced through the delivery pipe.Progressive Cavity pump

An inlet is provided for Priming that is essential for starting the pump. The progressive cavity pump is distinguished by these features. What comes first is high efficacy. Second, it may reach the very substantial pressure. The changes of the pressure almost do not affect the flow rate. Thus, this pump can provide the steady stream flow. The next feature is the pump has the use of self-priming, which is extremely convenient to transfer the mix of the fluid and gas. Pumping progressive cavity fluid from the reservoir to the base cavity of the cylinder causes the piston rod to be pushed upward, which pushes the fluid at another cavity back into the reservoir. This procedure pressurizes the room and extends the piston to its whole length. TheĀ progressive cavity pumps to the top section of the cylinder pushes the piston rod down, pushing the oil in another room back into the reservoir, completing the cycle.

If the Progressive cavity pump is especially designed, it Can also transport the sand fluid, concrete and so forth. Fourthly, its flow rate and pressure is famed for the comparatively large impulsive motion. Generally speaking, so as to produce the flow speed relatively even the air dome ought to be installed on the discharge line. What is more, the double-acting pump and the numerous progressive cavity pumps can clearly improve the heterogeneity of the flow. Last but not least, compared with the centrifugal pump, the progressive cavity pump has more intricate structure, bigger size and slower rate. Due to this above-mentioned attribute, an expert pump valve is necessary. There is absolutely not any doubt that the production cost and the installation cost are somewhat higher. The progressive cavity pump is principally applicable to furnish the water. The hand progressive cavity pump is utilized in the household life. In terms of the progressive cavity pump, it may offer the high-pressure fluid.
