Abstract
The utility model discloses a minitype deep well pump which belongs to the pump which is especially used for pumping liquid from the deep place, particularly a minitype deep well pump of which the driving device is positioned at ground. The minitype deep well pump comprises a motor, a pump body and a flexible shaft. The mini-type deep well pump is characterized in that one end of the flexible shaft is connected with a motor shaft, and a flexible shaft jacket of the other end of the flexible shaft is fixed to a cross beam of an n-shaped support bracket installed on the pump body. A flexible shaft core penetrating the support bracket is connected with a central shaft by a flexible shaft connector, and the inner part of the n-shaped support bracket is orderly provided with an upper fixing bracket, an upper fixing bracket bearing, an upper longitudinal fixer, a lower longitudinal fixer, a lower fixing bracket bearing, a lower fixing bracket and a universal connecting rod from top to bottom. The longitudinal fixer is fixedly connected with the central shaft, one end of the universal connecting rod is connected with the central shaft, and the other end is connected with a water pump shaft. The outer side of the pump body is coated with water pipes. The deep well pump of the utility model has good transmission performance and is especially suitable for a well with small caliber in countryside when the well can not be used in low-water period.
Description
Affiliated technical field
The utility model belongs to the miniature deep-well pump that the pump that is specifically designed to from the depths extracting liq, particularly drive unit are positioned at ground.
Background technique
Usually how deep-well pump connects motor and pump housing impeller with elongated rigidity major axis, this pump cost height, what have puts into the deep-well water lift with submersible pump, but common submersible pump is only applicable to bigbore well, the deep-well pump of flexible axle appears using in recent years, ZL90205180 discloses a kind of flexible axle pump, and it is to do transmission of power with flexible axle, and power is delivered on the impeller through flexible axle from belt pulley.Though replaced stiff shaft with flexible axle, be not suitable for small-bore family expenses well.
Summary of the invention
The purpose of this utility model be propose a kind of be applicable to the small-bore family expenses well in rural area do the technological scheme of the deep-well pump of transmission with flexible axle.
The technical solution of the utility model is, a kind of miniature deep-well pump, comprise motor, the pump housing, flexible axle, it is characterized in that: flexible axle one end is connecting motor reel, the flexible shaft jacket of the flexible axle the other end is fixed on the crossbeam of the ∏ shape support that is installed on the pump housing, the flexible axle core that penetrates in the frame links to each other with central shaft by the flexible axle connector, upper holder is housed in the ∏ shape support from top to bottom successively, the upper holder bearing, go up vertical fixture, following vertical fixture, the lower fixed frame bearing, lower fixed frame, universal connecting rod, described vertical fixture is fixedlyed connected with central shaft, universal connecting rod one end connects the central shaft the other end and connects water pump spindle, and the pump housing is with water pipe outward.
The described pump housing is a vertical-type axial-flow pump, can be screw rod pump or wing pump.
Described fixing frame bearing is a sliding bearing, can overlap bearing or graphite cannula bearing for alloy.
The beneficial effects of the utility model are that new micro deep-well pump all is installed in the water pipe, only needing during use that water pipe is inserted well casing connection power supply just can use, because water pump body need not vacuumize and be subjected to the influence of well depth under water, applied widely, because it is moving to have used vertical up and down fixture to guarantee that vertical string can not take place central shaft, universal connecting rod has improved powerdriven efficient.
The deep-well pump transmission performance that the technological scheme that the utility model provides is made is good, is specially adapted to the small-bore pumped well in rural area and can't uses during setting-out in dry season.
