Abstract

The invention discloses an energy-saving portable emergency pump which mainly comprises an integrated efficient permanent magnet motor, a bearing block, a front guide blade body, a mechanical sealing part, a filter screen, an open impeller and a quickly installed guide blade body. After passing through the front guide blade body, liquid mediums evenly symmetrically enter the impeller rotating at a high speed; through a quickly installed guide blade flow passage component, the hydraulic loss and fluid velocity are reduced, and the velocity energy can be converted into pressure energy. The energy-saving portable emergency pump has higher efficiency and flow than a conventional emergency pump, is light in weight and small in size and achieves remarkable functions such as small energy consumption, high flow, portability and no blockage.

Description

A kind of energy-saving portable formula is speedily carried out rescue work pump

Technical field

Background technique

At present because China is many sewerage systemdesign standard is too low, drainage capacity wretched insufficiency, just drains flooded fields with pump of speedily carrying out rescue work when the time comes.Pump of speedily carrying out rescue work in drought resisting, municipal engineering temporary drainage, fire-fighting emergent draining etc. in addition just also serves critical effect.

Conventional diving pump of speedily carrying out rescue work adopts the materials such as cast iron, and weight is very heavy, mobile difficulty, needs to adopt mechanical means to move at the scene of speedily carrying out rescue work.

To speedily carry out rescue work pump for powerful diving, owing to needing larger flow, its boundary dimension is comparatively large, for speedily carry out rescue work on-the-spot narrow place its move also very inconvenient.

The speedily carry out rescue work motor of pump of routine adopts threephase asynchronous, and electric efficiency and power factor are all lower, can not meet energy-conservation check requirements, and the weight of this motor is also heavier simultaneously, mobile also more difficult.

Summary of the invention

Object of the present invention is exactly to solve the problems referred to above that pump of speedily carrying out rescue work exists, and realizes having that efficient energy-saving, conveyance capacity are large, lightweight, the requirement of mobility strong, the pump fast moving that realizes speedily carrying out rescue work, to drain off floodwaters or the function of irrigating fast.

For achieving the above object, technological scheme of the present invention is: a kind of energy-saving portable formula is speedily carried out rescue work pump, comprises integrated high-efficiency magneto 1, bearing support 2, inlet guide vane body 3, mechanical seal 4, filter screen 5, unshrouded impeller 6 and ready-package diffuser 7.

Further, described integrated high-efficiency magneto 1 comprises upper bearing bracket 11, rotor 12, magneto 13 and casing 14, effectively shortens the length of motor.

Further, described magneto 13, owing to adopting permanent magnet excitation, has very large space and advantage in raising the efficiency.

Further, described bearing support 2 is built in motor internal, equally also significantly reduces the length of motor and decreases the leakage point of submersible pump.

Further, described inlet guide vane body 3 comprises guide ring 31, preposition spatial guide blade 32, air guide sleeve 33 and quick union (I) 34.Its effect ensures that the fluid entering impeller is even, axisymmetric, makes impeller have stable relative movement, reduce the hydraulic loss of impeller.

Further, described unshrouded impeller 6, has larger conveyance capacity.

Further, described ready-package diffuser 7 comprises quick union (II) 71, cylindrical shell 72, exit guide vane 73 and quick union (III) 74.Quick union (II) 71 matches with the quick union (I) 34 of inlet guide vane body.Its effect is the rotary motion that elimination fluid produces from impeller, reduces hydraulic loss and liquid speed, makes speed convert pressure energy to.

Further, motor housing, bearing support, inlet guide vane body, unshrouded impeller and ready-package diffuser material are aluminum alloy.

Starting electrical machinery, what medium made fluid well-distributing symmetry by inlet guide vane body 3 enters unshrouded impeller 6, and the impeller of High Rotation Speed makes liquid be transported to required place through the flow passage components of ready-package diffuser 7.

Compared to the prior art the present invention, has the following advantages:

The present invention has and to speedily carry out rescue work the higher efficiency of pump and conveyance capacity than routine, lighter weight and less volume, realizes that energy consumption is little, flow is large, portable and without significant functions such as blockings.
