Description
Technical field
The present invention relates to a kind of self-priming pumping unit, belong to fluid machinery technical field.It is mainly used in solving when suction liquid
When face is under impeller, the liquid problem conveyed should be filled into pump case in advance by starting Ordinary Centrifugal Pumps.
Background technology
Pump, which is mainly used to conveying liquid, includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid metal etc., also can be defeated
Liquor charging body, admixture of gas and the liquid containing suspended solids, are widely used in petrochemical industry, agricultural, mining industry, metallurgy, electricity
In the industries such as power, nuclear power station, national defence, naval vessels or field.By operation principle point, pump is divided into positive displacement pump and impeller pump.Volume
Formula pump causes swept volume periodically to increase and reduce and suction liquid by the motion of workpiece, and by workpiece
Extrude and directly increase the pressure energy of liquid.Impeller pump is to drive liquid at high speed revolution by impeller and mechanical energy is transmitted
To the liquid conveyed.For Ordinary Centrifugal Pumps, if suction liquid level must fill into pump case in advance under impeller, during startup
The full liquid conveyed, operation are inconvenient.In order to be filled with the liquid conveyed in pump case, generally in suction line entrance
Bottom valve is installed.When the pump is operated, bottom valve causes very big hydraulic loss.And self priming pump can be not required to liquid filling body before activation, warp
Short-time running is crossed, by the effect of pump in itself, you can so that liquid is drunk up, put into normal work.Current self priming pump has very
Polymorphic type, but mostly exist：(1) it is complicated；(2) the problems such as suction capacity is not strong.Therefore, one kind that research and development are economic, practical
Self priming pump is very necessary.
The content of the invention
The technical problem to be solved in the present invention is to combine positive displacement pump and impeller pump, solves the anti-cavitation of pump
Problem and a kind of self priming pump for improving suction capacity.
The present invention provides a kind of a kind of self priming pump with following structure to solve above technical problem.It is by base

Worm screw 20, vane pump 21, blade pumping intake piping 22, flange 23, blade pump discharge pipe 24 and suction line 25 form, and are characterized in,
Bearing housing 2, vane pump 21 are fixed on base 1, and dump valve 9, inlet valve 12 and diaphragm pump upper casing 10 fit together, diaphragm
Pump upper casing 10, diaphragm 8 are fixed on diaphragm pump lower casing 6 by fixing screws 13, and diaphragm pump lower casing 6 is fixed on bearing housing 2,
Guide holder 7 is placed in diaphragm pump lower casing 6, and spring 16 is placed between guide holder 7 and slide bar 15, and slide bar 15 passes through screw 11 and film
Piece 8 is fixed together, and slide bar 15 is connected together by pin 5 and connecting rod 17, and connecting rod 17 is connected together by pin 5 and toggle-action lever 18,
Toggle-action lever 18 is fixed together with worm gear 19, and worm gear 19 and worm screw 20 form worm mechanism, discharge pipe 14 and dump valve 9 and leaf
Piece pump discharge pipe 24 is connected, and suction line 25 is connected with inlet valve 12 and blade pumping intake piping 22.
A kind of preferably embodiment of this technology solution is a kind of self priming pump of this structure, by returning for pump shaft 4
The dynamic linear motion that slide bar 15 is converted into by worm mechanism and slider-crank mechanism of transhipment, the linear motion up and down of slide bar 15
Band dynamic diaphragm 8 moves, and changes the spatial volume size that diaphragm 8 is formed with diaphragm pump upper casing 10, so that vane pump 21 enters
Mouth end forms vacuum, reaches the purpose of pump self-priming.
