Micro spiral pump system

Abstract

The invention discloses a micro spiral pump system. The micro spiral pump system is characterized in that the system comprises a pump head (1) and a pump body (7) connected with the pump head (1) through a connecting pipeline (6), and a spiral rotary shaft (2) is arranged in the pump head (1). Compared with the prior art, the micro spiral pump system has the advantages that a screw rod is replaced with the spiral rotary shaft, water flow is driven by spiral blades, the centrifugal force of the spiral blades is small compared with the action of the screw rod, therefore, vibration is slight, and a universal joint is not prone to damage; besides, a filtering screen is additionally installed at a water inlet end, so that impact of gravel to the universal joint in the pump body is reduced, a good effect is achieved, durability of the pump head is improved, and the service life of the pump head is prolonged; and a motor is provided with a converter which can selectively input two voltages, electricity can be transmitted to a 48-60V socket through a storage battery in case of a power failure, the production requirement that operation continues in case of the power failure is met, and the operating efficiency of the pump body is improved.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a micro screw pump system. Background technique [0002] Northern Anhui is an arid area, especially in winter, where water shortages are serious, so it is necessary to draw water from groundwater layers 1,000 meters or even deeper. The existing pump head generally adopts a screw structure, and the vibration of the pump head is relatively severe during the pumping process. The vibration of the connecting shaft and the screw is aggravated due to centrifugal action, which easily damages the universal joint, causing the connecting shaft and the screw to be disconnected and separated. Some pump bodies can only support 220V voltage operation, and cannot operate if there is a power failure. Based on this, a micro-screw pump system is now studied, which solves this problem well. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of t...
