Description

Screw pump capable of being maintained quickly

Technical Field

The invention belongs to the technical field of screw pumps, and particularly relates to a rapid maintenance screw pump.

Background

The screw pump is also called a screw pump, also called a screw water raiser and an Archimedes screw pump. A pump for spirally raising water body along axial direction by utilizing rotation of helical blade. Consists of a shaft, a helical blade and a shell. When pumping water, the pump is obliquely arranged in the water, so that the inclination angle of the main shaft of the water pump is smaller than that of the helical blade, and the lower end of the helical blade is contacted with the water. When the prime motor drives the screw pump shaft to rotate through the speed changing device, water enters the blades and rises along the spiral flow channel until the water flows out. Simple structure, easy manufacture, great flow, small head loss, high efficiency, convenient maintenance, low lift, low rotation speed and need of speed variator. Is mainly used for irrigation, drainage and lifting sewage, sludge and other occasions. The spiral pump device used in China from the 70 th 20 th century comprises a prime mover, a variable speed transmission and a spiral pump, and is specifically composed of a spiral blade 1, a pump shaft 2, a bearing seat 3 and a shell 4 as shown in figure 1. The screw pump is obliquely arranged between the upper water pool and the lower water pool, and the lower end blade of the screw pump is immersed below the water surface. When the pump shaft rotates, the helical blades push water in the water tank into the blade grooves, and the water is lifted upwards along the primary stage of the helical shaft under the action of the helical rotating blades until reaching the water outlet of the helical pump. The screw pump only changes the potential energy of fluid, and is different from a blade type water pump which converts mechanical energy into the potential energy and kinetic energy of conveyed liquid, and the screw pump is divided into a single screw pump, a double screw pump and a three-screw pump according to the number of screws.

When the common screw pump is maintained, the outlet flange, the stator and the feeding cavity are sequentially disassembled from the outlet flange end or the speed reducing motor end, or the speed reducing motor, the feeding cavity and the stator are disassembled firstly, so that time and labor are wasted, and the working efficiency is reduced.
