Problems solved by technology

[0006] In order to increase the outlet pressure and lift of some existing pumps used in fire protection, industrial engineering and agricultural engineering, some pumps are designed as multi-stage centrifugal combined pumps with multi-stage centrifugal combined structure. The multi-stage centrifugal combined pumps cannot balance the axial force and Radial force, large vibration, high noise, large wear and tear on mechanical seals, poor sealing performance, easy to leak, and easy to release pressure; some pumps increase the speed and pressure through frequency conversion pumps. The disadvantages of stability, large size and high failure rate

Abstract

The invention discloses a spiral flow high-lift constant pressure pump body. The pump body mainly comprises an upper shell and a lower shell connected with the upper shell. The upper shell comprises a water outlet pipe, a water inlet pipe and a cavity; The cavity comprises a smooth cavity wall and a cambered surface flow guide groove formed in the top of the cavity wall. A size-adjustable impeller mechanism is arranged at the center in the cavity. The impeller mechanism comprises a driving rotating shaft, an impeller, a plurality of telescopic grooves, a first sliding way, fan blades, a center shaft, a plurality of third sliding ways, a fixing ring, a second sliding way, a driving chain, a driving ring and an electric telescopic rod, wherein a connecting column is arranged on the fan blade, the connecting column is slidably arranged in the second slide way, and the other end of the connecting column is connected with a second slide block; and the driving chain is connected to the connecting column, and the driving chain is located at one end in the third sliding way and connected to the driving ring through one connecting block. By arranging the impeller capable of adjusting the water pumping radius, remote control can be completed under the condition that the sealing performance of the pump body is guaranteed, and the lift of the pump body can be changed through the change of the water pumping radius.

Description

Technical field [0001] The present invention relates to the field of constant pressure pumps, and more particularly to a helical flow of high roll pump pump. Background technique [0002] The constant pressure pump is a pump that keeps the output pressure constant. The flow changes as the external resistance changes. [0003] The pressure of the constant pressure pump set is that the basic principles of the system preparation needed, and the basic principle of "hydraulic system pressure is determined by the load", which is limited by the overflow valve, is determined by the load, and is constant The pressure pump is added to limit, and the reaction force is large and the pressure is adjusted by the constant pressure pump. [0004] With the continuous development of industrial and agriculture, it is getting wider and wider using constant pressure to deliver liquid. At present, most of my country's production and use is still a traditional centrifugal pump, and the pump is low, and...
