Abstract
A kind of corrosion protection suction engine, comprises body, impeller, axle, bearing, seal ring, motor, body there are water intake and water outlet, motor is connected with one end of axle by coupling, and axle is by bearings on body, and the other end of axle connects impeller, by seal ring seal between axle and body, be provided with the rotary cover of opening and closing openings at body near bottom position.The packing ring that sealing is provided is arranged between lid and body.Lid comprises drainage channel and locking device, and the drainage channel being communicated with internal body is positioned at the bottom of lid.Described locking device comprises screw rod, and the outer end of screw rod has the chain being connected to rotary cover.By the screw rod draining unloading rotary cover or screw out on rotary cover, avoid the accumulation of water in suction engine.
Description
Technical field
The utility model relates to a kind of corrosion protection suction engine, belongs to water conservancy equipment field.
Background technique
Suction engine has another name called " water pump ", is conveying liquid or the machinery making fluid pressurization.Be widely used in hydraulic engineering, field irrigation, industrial feedwater, draining.Suction engine sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to conveying liquid and comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The type such as positive displacement suction engine, blade type suction engine can be divided into according to different working principle suction engine.Positive displacement suction engine utilizes the change of its swept volume of a single chamber to carry out transferring energy; Blade type suction engine utilizes the interaction of rotary vane and water to carry out transferring energy, has the type such as centrifugal suction engine, axial flow suction engine.The essential structure of centrifugal suction engine is made up of five parts, respectively: impeller, and body, axle, bearing, seal ring.Impeller is the core of centrifugal pump, and its rotating speed high output is large, and the blade on impeller plays Main Function again, and impeller will be tested by static balancing before assembly.Inner and outer surface on impeller requires smooth, to reduce the frictional loss of current.Body is the main body of suction engine, plays support fixation, and is connected with bearings mounted bracket.The effect of axle borrows coupling to be connected with motor, and impeller is passed in the torque of motor, so it is the critical piece transmitting mechanical energy.Bearing is enclosed within component pump shaft supporting pump shaft, has rolling bearing and two kinds, sliding bearing.Seal ring also known as subtracting leakage ring, for the gap between stuffing box bearing and body.
Centrifugal suction engine of the prior art is after having drawn water, and usually remaining in body have water, not easily discharges, and the weight both having increased suction engine makes it not easily move, and also can corrode suction engine inside in the course of time, affects the suction engine life-span.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of convenient corrosion protection suction engine of discharging residual water.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of corrosion protection suction engine, comprises body, impeller, axle, bearing, seal ring, motor, body 1 has water intake and water outlet, and motor is connected with one end of axle by coupling, axle by bearings on body, the other end of axle connects impeller, by seal ring seal between axle and body, is provided with the rotary cover of opening and closing openings at body near bottom position.The packing ring that sealing is provided is arranged between lid and body.Lid comprises drainage channel and locking device, and the drainage channel being communicated with internal body is positioned at the bottom of lid.Described locking device comprises screw rod, and the outer end of screw rod has the chain being connected to rotary cover.
Rotary cover can be fixed to body by the connecting mode that can remove suitable in addition, connects as by bayonet socket.
Rotary cover 7 is provided with handle.
The utility model is reasonable in design, easy to use, by the screw rod draining unloading rotary cover or screw out on rotary cover, can avoid the accumulation of water in suction engine, and the use of screw rod can be avoided often unloads rotary cover and cause poorly sealed and leaking.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the front elevation of rotary cover of the present utility model;
Fig. 3 is the sectional view of drainage channel of the present utility model lid in the closed position;
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details;
As Figure 1-3, for solving the problems of the technologies described above, technical solution adopted in the utility model is a kind of corrosion protection suction engine, comprise body 1, impeller 2, axle 3, bearing 4, seal ring 5, motor 6, body 1 there are water intake and water outlet, motor 6 is connected by coupling one end with axle 3, and axle 3 is supported on body 1 by bearing 4, and the other end of axle 3 connects impeller 2, sealed by seal ring 5 between axle 3 and body 1, be provided with the rotary cover 7 of opening and closing openings at body 1 near bottom position.The packing ring that sealing is provided is arranged between rotary cover 7 and body 1.Rotary cover 7 comprises drainage channel 71 and locking device, and drainage channel 71 is positioned at the bottom of rotary cover 7.Described locking device comprises screw rod 72, and the outer end of screw rod 72 has the chain 73 being connected to rotary cover 7.
Rotary cover 7 can be fixed to body by the connecting mode that can remove suitable in addition, connects as by bayonet socket.
Rotary cover 7 is provided with handle.
During use, by screwing out screw rod 72 or unloading rotary cover 7, residuary waters is discharged.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, the change made, remodeling, interpolation or replacement, all should belong to protection domain of the present utility model.
