Abstract
The utility model relates to a micro pump, its characterized in that: adopt pump shaft and rotor shaft integral type structure, the motor directly allies oneself with with the pump body, and the one end and the motor of hookup end cover passes through the front end housing of bolt immobilization connection component motor as an organic whole, and the other end passes through the bolt assembly together with the pump body, the motor shaft passes in the hookup end cover stretches into the pump chamber, and the impeller setting is on the screw of motor spindle front end, and the screw revolves to opposite with motor direction of rotation, the hookup end cover is equipped with the quiet ring of mechanical seal in the sealing chamber of pump body one side, vice in a set of friction of the epaxial mechanical seal rotating ring of motor formation with the setting, the hookup end cover is equipped with deep groove ball bearing in one side of motor. The utility model discloses motor shaft and pump shaft adopt a body structure, but wide application in fields such as field irrigation, construction, high building water, food processing have characteristics such as application range guangZhou, multipurpose, small, light in weight, lift height, removal, installation and convenient to use, and the total head does not have the overload.
Description
Technical field
The utility model belongs to farm machinery, relates to a kind of miniature horizontal pump, particularly the micropump of a kind of motor and pump straight connection type.
Background technique
At present, in known technology, agricultural irrigation water pump structure is made up of pump head, support and pump case, be water intake in the bottom surface of pump case, water outlet is in the side of water pump, and by bearing assemble main shaft on the central axis of support, the end of main shaft to be in pump case and impeller is housed.Although this water pump structure is simple, its water intake and water outlet adopt to be threaded or flange connect, and existence is moved, install and use all inconvenient problem.Because the space of pump head cavity is too small, also there is lift little, the problem of suction capactity difference.
Summary of the invention
The utility model overcomes the defect of above-mentioned existence, and object is the industries such as agricultural irrigation, construction, high building water, food processing, provides a kind of lift large, moves, installs and use micropump all easily.
The utility model micropump content Description:
The utility model micropump, it is characterized in that: be made up of the pump housing, impeller, mechanical seal, connection end cap, motor and water outlet, adopt pump shaft and rotor shaft integral structure, motor and pump housing direct connection, one end of connection end cap and motor are bolted to be connected as one and form the front cover of motor, and the other end and the pump housing pass through together with bolts assemblies; Motor shaft stretches in pump chamber through connecting end cap, and impeller is arranged on the screw thread of electric machine main shaft front end, and thread rotary orientation is contrary with motor sense of rotation; Connect end cap and be provided with mechanical sealing static ring in the closed chamber of pump housing side, form one group of friction pair with the mechanical sealing linkage ring be arranged on motor shaft, connect end cap and be provided with deep groove ball bearing in the side of motor.
The utility model micropump, motor shaft and pump shaft adopt integrative-structure, and have employed the connection end cover structure of compact structure, shorten the length of shaft that drives impeller rotates, ensure to reduce the stability that impeller runs the vibrations that motor shaft produces when high speed operation, play the effect of damping noise reduction.The fields such as field irrigation, construction, high building water, food processing can be widely used in, and be applicable to that spread of voltage, variations in the voltage are comparatively large or low voltage is regional, have that using scope is wide, multipurpose, volume are little, lightweight, lift high, mobile, easy to install and use, total head No-mistake Principle.
Accompanying drawing explanation
Fig. 1 is micropump structural representation;
Fig. 2 is micropump structure side view;
In figure: 1 be the pump housing, 2 are impellers, 3 is mechanical seal, 4 be that to connect end cap, 5 are motors, 6 are water outlets, 7 is deep groove ball bearings.
Embodiment
The utility model micropump is achieved in that and illustrates below in conjunction with accompanying drawing.See Fig. 1, Fig. 2, micropump by: the pump housing 1, impeller 2, mechanical seal 3, connect end cap 4, motor 5 and water outlet 6 form, adopt pump shaft and rotor shaft integral structure, motor 5 and the pump housing 1 direct connection, one end of connection end cap 4 and motor 5 are bolted and are connected as one, and as the front cover of motor 5, the other end and the pump housing 1, by together with bolts assemblies, play the effect of closed pump chamber.Motor shaft stretches in pump chamber through connecting end cap 4, and impeller 2 is arranged on the screw thread of motor 5 front-end of spindle, and thread rotary orientation is contrary with motor 5 sense of rotation.Connect end cap 4 in the closed chamber of the pump housing 1 side, be provided with mechanical seal 3 stationary ring, one group of friction pair is formed with mechanical seal 3 rotating ring be arranged on motor 5 axle, the stable distance of impeller 2 wheel hub end face and sealed type bottom surface, in certain dimensional range, ensures the seal request of pump chamber.Connect end cap 4 and be provided with deep groove ball bearing 7 in the side of motor 5, play support motor axle and ensure its effect steadily rotated.
The utility model is miniature is work like this: start electric pump, motor 5 drives impeller 2 High Rotation Speed, water, under impeller 2 and the pump housing 1 acting in conjunction, flows into from the suction port of the pump housing, flows out from water outlet 6.Connect end cap 4 owing to have employed, motor 5 and impeller 2 Distance Shortened, the rotary centrifugal force of shaft extension is controlled, can stable operation, reduces overall unit running noise.
The utility model micropump, motor shaft and pump shaft adopt integrative-structure, and have employed the connection end cover structure of compact structure, shorten the length of shaft that drives impeller rotates, ensure to reduce the stability that impeller runs the vibrations that motor shaft produces when high speed operation, play the effect of damping noise reduction.
The utility model can be widely used in the fields such as field irrigation, construction, high building water, food processing, and be applicable to that spread of voltage, variations in the voltage are comparatively large or low voltage is regional, have that using scope is wide, multipurpose, volume are little, lightweight, lift high.It moves, install and use all very convenient, total head No-mistake Principle.
