It includes the pump seat, a housing, the cylinder, the rotor, the scraper blade, a spring, the breathing pipe, the oil tank, the air bleeding valve, the blast pipe, the pump seat sets up in the bottom position, the casing sets up above the pump seat position and rather than linking firmly, the cylinder sets up in the inboard intermediate position of casing, rotor eccentric settings is in the inboard position of cylinder, two scraper blades set up in rotor outside groove position with parallel form, the spring sets up in two scraper blade intermediate positions, the oil tank sets up above the casing position and rather than linking firmly, the cylinder is connected with the lower extreme to the breathing pipe, the vertical limit position of keeping right that sets up of oil tank form is run through on upper portion above the casing, the air bleeding valve sets up in the inboard lower part the left side position of oil tank with sub -unit connection cylinder form, the blast pipe sets up position above the oil tank in order to run through oil tank upper wall form. The utility model has the characteristics of as follows: job stabilization is reliable, fills the water yield during start -up and can reduce by a wide margin, not only alleviates intensity of labour but also improve labor efficiency.
Description
Technical field:
The utility model belongs to rural area field irrigation and to draw water technical field, relates to a kind of scraper-type vacuum pump.
Background technique:
Vacuum pump is mainly used in large centrifugal pump and vacuumizes water-filling in the machinery of rural irrigation.Rural area field irrigation needs suction engine to draw water provides water source.And the water pump of existing rural area suction engine is large because of required pump footpath, generally all adopt centrifugal pump, when centrifugal pump starts, necessary water-filling (water), could extract water out after only having the air got rid of in suction line and pump.Because water pump pump footpath is large, pipeline is long, required filled water amount is just large, by water-filling of manually carrying water, has both required great effort also time-consuming, and has added the burden of peasant household.But large centrifugal pump suction engine used is concentrated in rural area, conventional filled water amount is larger, and water-filling is more difficult, and as adopted centrifugal vacuum pump, filled water amount required during startup can significantly reduce, thus raises labour efficiency.
Model utility content:
The purpose of this utility model provides a kind of scraper-type vacuum pump for above-mentioned situation.
The technological scheme that the utility model adopts:
A kind of scraper-type vacuum pump, it comprises pump seat, housing, cylinder, rotor, scraper plate, spring, sucking pipe, fuel tank, outlet valve, outlet pipe, pump seat is square plate face seat, housing is round shape shape, cylinder is cylinder, rotor is the rotating shaft of outside in groove surface, scraper plate is strip board, sucking pipe is circular pipeline, fuel tank is cylindrical shape, outlet valve is cap type overhead-valve, outlet pipe is vent connection, pump seat is arranged at bottom position, housing is arranged at pump seat upper position and is connected with it, cylinder is arranged at case inside neutral position, rotor eccentricity is arranged at cylinder inner side, two pieces of scraper plates are arranged at groove location outside rotor with parallel fashion, spring is arranged at two pieces of scraper plate neutral positions, fuel tank is arranged at housing upper face position and is connected with it, sucking pipe connects cylinder with lower end, top is run through fuel tank form and is vertically arranged at housing upper face by location right, outlet valve connects cylinder form with bottom and is arranged at fuel tank lower inside left position, outlet pipe is arranged at fuel tank upper position to run through fuel tank upper wall form.
The utility model, during work, when rotor rotates in the cylinder, due to the effect of inertial centrifugal force and spring, make to scrape pole and scrape row along cylinder inner wall, now, the volume of the left and right cavity formed between scraper plate and cylinder constantly changes in the rotation process of rotor, right cavity constantly expands, and left cavity reduces gradually, gas just can suck from sucking pipe, and be compressed in cavity, when the pressure of gas exceedes the resistance of outlet valve, gas just through outlet valve to fuel tank, again by outlet pipe Exhaust Gas, vacuum pump is made to be in vacuum state, just water-filling can be carried out to pump.
The utility model, described outlet valve, adopts the design be immersed in fuel tank, its object is to prevent gas backstreaming from arriving in cylinder.Be water conservation layer outside cylinder, play cooling action with countercylinder wall.
The utility model has following features: working stability is reliable, and during startup, filled water amount can significantly reduce, and not only reduces labor intensity but also raise labour efficiency.
Accompanying drawing illustrates:
Fig. 1 is scraper-type vacuum pump structure generalized section, its description of symbols: pump seat 1, housing 2, cylinder 3, rotor 4, scraper plate 5, spring 6, sucking pipe 7, fuel tank 8, outlet valve 9, outlet pipe 10, left cavity 11, right cavity 12, water conservation layer 13.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of scraper-type vacuum pump, it comprises pump seat 1, housing 2, cylinder 3, rotor 4, scraper plate 5, spring 6, sucking pipe 7, fuel tank 8, outlet valve 9, outlet pipe 10, pump seat 1 is square pole-face seat, housing 2 is in round shape shape, cylinder 3 is cylinder, rotor 4 for outside be the rotating shaft of groove surface, scraper plate 5 is strip board, sucking pipe 7 is circular pipeline, fuel tank 8 is in simplified shape, outlet valve 9 is cap type overhead-valve, outlet pipe 10 is vent connection, pump seat 1 is arranged at bottom position, housing 2 is arranged at pump seat 1 upper position and is connected with it, cylinder 3 is arranged at neutral position inside housing 2, rotor 4 eccentric setting is in cylinder 3 inner side, two pieces of scraper plates 5 are arranged at groove location outside rotor 4 with parallel fashion, spring 6 is arranged at two pieces of scraper plate 5 neutral positions, fuel tank 8 is arranged at housing 2 upper position and is connected with it, sucking pipe 7 connects cylinder 3 with lower end, top is run through fuel tank 8 form and is vertically arranged at housing 2 above by location right, outlet valve 9 connects cylinder 3 form with bottom and is arranged at fuel tank 8 lower inside left position, outlet pipe 10 is arranged at fuel tank 8 upper position to run through fuel tank 8 upper wall form.
