Abstract
The invention relates to a multifunctional self-priming centrifugal pump without starting medium. The electromagnetic vibration vacuum pump is a cylindrical structure integrating a machine and a pump, a motor rotor and an impeller are coaxially driven, a suction inlet and a discharge outlet are arranged in an axial line, and an outlet end of a guide shell is provided with an electromagnetic vibration vacuum pump for exhausting and guiding water for the impeller. The pump overcomes the defects of various pumps in the prior art, and has the advantages of simple structure, low cost, high efficiency, light weight, electric energy saving and the like. The invention can also be suitable for various configurations and working environments, and particularly can be directly connected with a pipeline or connected in series underground to extract the underground water in an ultra-deep layer.
Description
The present invention relates to a kind of water pump.
Widely used vane pump in the prior art, there are a lot of shortcomings, need install bottom valve or exhaust water diversion apparatus such as centrifugal pump, the self-priming pump that has the exhaust water diversion apparatus, before work, still need pour into moving medium, and self-priming time is long, efficient is low, complex structure, use and install all inconveniently, especially can not be applicable to deep-well.Though submersible pump has solved starting diversion problem, but in order to make motor can adapt to diving work, must take a series of complicated technology measures, thus efficiency of motor is low, poor reliability, life-span short, maintenance and safeguard all very difficult, need often submersible pump is left the water discharge water inspections, also be not suitable for series connection use under deep-well.
Task of the present invention is the shortcoming at above-mentioned all kinds of pumps, provide a kind of simple in structure, need not play moving medium, can adapt to various configurations and various working environment, easy to install and use, efficient is high, save electric energy, especially can extract the vane pump of deep water easily.
The present invention finishes as follows: it is the cylinder-like structure of pump unification, rotor (9) and the same shaft drive of impeller (2), suction port and exhaust port are an axis arranged, can be the electric and magnetic oscillation vacuum pump of impeller (2) exhaust diversion in the exhaust port end installing of leading shell (11), it blocks the passage of suction sleeve and lifting pipe by the check valve that is installed in the exhaust port end (13), and the air in the suction sleeve is extracted out through check valve core hole (17).
Describe the present invention below in conjunction with accompanying drawing.
The present invention is by pump cover (1), impeller (2), pump case (3), pump case muscle (4), relief hole (5), seal ring (6), casing (7), stator (8), rotor (9), casing muscle (10), lead shell (11), lead shell muscle (12), check valve (13), spilled water hole (14), trimmer valve (15), cushion pad (16), check valve core hole (17), spring (18), switch (19), cable (20), electromagnetic vibration machine is led shell (21), electric and magnetic oscillation casing (22), coil (23), iron core (24), spring (25), inhale iron (26), barrier film (27), pump case (28), suction valve (29), expulsion valve (30) and bolt (31) constitute.
Pump case (3), casing (7) and lead shell (11) respectively by pump case muscle (4), casing muscle (10) with lead shell muscle (12) and cut apart constitute the bivalve body, thereby formed fluid space.Bolt (31) is by passing in the hole of leading shell (11) and casing muscle (10), and axial end connected and sealing by the screw on seal ring (6) and pump case muscle (4) top.The inlet limit of pump case muscle (4) and the outlet limit of leading shell muscle (12) also are the overcurrent stator.High pressure water is crossed fluid space by pump case (3), casing (7) and the bivalve body of leading shell (11) and is passed through, and cools off stator (8) simultaneously.Cable (20) penetrates by leading in the shell muscle (12), motor and electromagnetic vibration machine synchronization control in parallel.
The electromagnetic vibration machine that is made of coil (23), iron core (24), spring (25), suction iron (26) and barrier film (27) is encapsulated in the electric and magnetic oscillation casing (22), connect with the end face of electric and magnetic oscillation casing (22) and seal by barrier film (27) and pump case (28), constitute the electric and magnetic oscillation vacuum pump.Iron core (24) and coil (23) produce alternating magnetic field because alternation changes and the reaction force of spring (25), sucks or loosens and inhale iron (26), simultaneously, agitates barrier film (27) reciprocating, so, the air in the suction sleeve is sucked and discharge; Air in the suction sleeve enters pump case (28) through check valve core hole (17) and suction valve (29), discharges through expulsion valve (30) again.When the air in the suction sleeve is excluded, water is under atmospheric effect, be full of suction sleeve and enter impeller (2), at this moment impeller (2) beginning proper functioning, check valve (13) is pushed open by high pressure water, switch (19) but under the effect of high pressure water the circuit of automatic disconnection electromagnetic vibration machine, electromagnetic vibration machine is quit work.Switch (19) can be pressure sensitive switch or non-contact switch.This shows that motor of the present invention is a starting under no load, have only the electromagnetic vibration machine loaded work piece this moment, when impeller (2) when being filled water pump just begin proper functioning, the work of electromagnetic vibration machine simultaneously stops.Therefore starting current of the present invention is very little, and obviously this is to the starting of pump with to prevent that line voltage from falling all very favourable.And can reduce match power accordingly, save a large amount of electric energy.Shaft sealing leakage liquid is in time drained by relief hole (5), scurries into motor to prevent high pressure water.During termination of pumping, check valve (13) is closed rapidly under the effect of hydraulic pressure impact and spring (18).Trimmer valve (15) is with material or the hollow elasticity made of density less than water.Under the buoyancy of water effect, can be floated by water.At this moment the water in the lifting pipe is slowly flowed back in the well by spilled water hole (14), and after current were most, trimmer valve (15) can be sealed spilled water hole (14) again by deadweight.When horizontally-arranged use, can promote the outlet sealing that check valve (13) will be led shell (11) by spring (18).
Pump of the present invention is to break away from water surface installation and operation, only has suction hose to be immersed in the water, and the therefore motor of the present invention impact of not soaked is not so motor need be taked waterproof measure; It adopts common dry type motor, and by the working water cooling, so good cooling results. Compare with submersible motor, the present invention can significantly improve electric efficiency, and technology is simple, and cost is low. Compare with other all kinds of pumps, the present invention need not pour into moving medium, and starting under no load, so starting current is little, can significantly reduce match power, weight reduction and saving electric energy. It can directly connect or inline downhole with pipeline, extracts the underground water of any degree of depth. Thereby overcome prior art because unit group lift deficiency, can not extract ultradeep well water or because unit group lift designs the too high shortcoming such as margin head loss that causes. Moreover use of the present invention is not subjected to the restriction of well depth and orographic condition, so can take to wait horizontally, vertically, inclinedly various forms to install and use annex and the hydraulic loss that has reduced pipeline. Especially can be at inline downhole, extract ultradeep well water, have power saving, easy to install and use, compact conformation, the advantage such as in light weight, durable in use.
The present invention is applicable to various vane pumps.
