Minitype deep water pump

Abstract

The invention relates to a pump used for extracting liquid from deep, and particularly relates to a driving device, namely, a minitype deep water pump positioned on the ground. The deep water pump comprises a motor, a flexible shaft and a pump body; the deep water pump is characterized in that one end of the flexible shaft is connected with a motor shaft, and the other end of the flexible shaft is mutually connected with the pump body through a flexible shaft connector; the pump body is composed of a support, a longitudinal fixer, bearings, a central shaft, and a universal connecting rod, wherein the longitudinal fixer is fixedly connected with the support; one end of the central shaft is connected with the flexible shaft connector, the other end of the flexible shaft connector is mutually connected with the universal connecting rod, and the two ends of the longitudinal fixer are provided with bearings; and the central shaft can be taken out from the flexible shaft end so as to change the bearings arranged on the two ends of the longitudinal fixer. The minitype deep water pump provided by the invention has the advantages of simple structure and convenience in maintenance, and is particularly suitable for small-bore household wells, and is easy to use.

Description

1. Technical field: [0001] The invention relates to a pump for extracting liquid from a deep place, in particular to a miniature deep water pump whose driving device is located on the ground. 2. Background technology: [0002] Usually, deep well pumps use submersible pumps to lift water in deep wells, but ordinary submersible pumps are only suitable for large-diameter wells. In recent years, deep well pumps using flexible shafts have appeared. Passed on the impeller, although the rigid shaft is replaced by a flexible shaft, it is not suitable for small-diameter domestic water wells. [0003] In addition, if the flexible shaft is placed in water, it is not easy to maintain due to long-term immersion corrosion. 3. Contents of the invention: [0004] The invention overcomes the deficiencies in the prior art and provides a technical proposal for a deep well pump which is suitable for maintenance and is suitable for small-diameter household water wells in rural areas and uses ...
