Abstract
The utility model relates to a strong self-absorption fire-fighting pump and belongs to fire-fighting pumps, wherein a motor and a pump are fixedly connected with a machine base, a water inlet valve body and a water outlet valve body are respectively connected with the pump, a main shaft box is fixedly connected with the machine base, an output shaft of the motor is fixedly connected with a main shaft in the main shaft box through a coupler, the main shaft is movably connected with an eccentric gear through a bearing, an outer portion of the eccentric gear is connected with a ring-type rolling bearing in a sleeve mode, an outer portion of the rolling bearing is connected with an eccentric sleeve in a sleeve mode, a pressing disk one and the main shaft box form an air absorption chamber one, and a pressing disk two and the main shaft box form an air absorption chamber two. As a pump body and a strong self-absorption device are effectively designed to be an integrated structure, the strong self-absorption fire-fighting pump has the advantages that the structure is novel, self-air-pumping and self-water-drainage are achieved, water filling is not needed when the pump is started, a vacuum pump and a bottom valve do not need arranging, operation is easy, thereby being widely applied to the fire-fighting field.
Description
Technical field
The utility model belongs to fire water pump, refers in particular to a kind of strong self-priming fire water pump.
Background technique
Present domestic fire-protection equipment, majority is old-fashioned PW pump, IS pump and SH pump, needs to install in addition a cover vacuum pump the discharge of the gas in inlet pipeline and the pump chamber, pump could be worked; And efficient is low, and is long from period of exhaust, and the self-priming height is low; Volume is big, and floor space is big, and power consumption is big.Vacuum pump adopts Nash hytor more, this kind pump must be in pump before starting for the first time fills with water, every afterwards first quarter moon water filling once, operation, keep in repair more loaded down with trivial details.
Summary of the invention
The utility model relates to a kind of strong self-priming fire water pump, to solve the loaded down with trivial details problem of traditional type vacuum pump operation maintenance.
The technological scheme of the utility model is: motor is fixedly connected with support, and pump is fixedly connected with support, and water inlet valve body, water outlet valve body are fixedly connected with pump respectively; Headstock is fixedly connected with support, and the output shaft of motor is fixedly connected with the interior main shaft of headstock through coupling, and main shaft is rotationally connected through bearing and eccentricity gear; Eccentricity gear outer cover T-Ring formula rolling bearing, the outside socket eccentric bushing of ring type rolling bearing, planetary pinion and eccentricity gear are connected with a joggle; Sliding gear and main shaft are slidingly connected, and sliding gear and planetary pinion are connected with a joggle, and track bar is fixedly connected with eccentric bushing; Platen one is fixedly connected with track bar respectively with platen two; End cap one is fixedly connected with headstock through seal ring respectively with end cap two, and platen one forms induction chamber one with headstock, and platen two forms induction chamber two with headstock; Pneumatic tube one end is fixedly connected with air absorbing mouth, and the other end is fixedly connected with the water inlet valve body.
The advantage of the utility model is: novel structure, the pump housing and strong self-suction device effectively are designed to integrative-structure, and can bleed voluntarily, draining, need not pour water during startup, without the peripheral hardware vacuum pump, easy and simple to handle without bottom valve, can be widely used in fire-fighting domain.

Embodiment
Motor 1 is fixedly connected with support 2, and pump 3 is fixedly connected with support 2, and water inlet valve body 4, water outlet valve body 5 are fixedly connected with pump 3 respectively; Headstock 6 is fixedly connected with support 2, and the output shaft of motor 1 is fixedly connected with headstock 6 interior main shafts 8 through coupling 7, and main shaft 8 is rotationally connected through bearing 10 and eccentricity gear 9; Eccentricity gear 9 outer cover T-Ring formula rolling bearings 11, the outside socket eccentric bushing 12 of ring type rolling bearing, planetary pinion 13 is connected with a joggle with eccentricity gear 9; Sliding gear 14 is slidingly connected with main shaft 8, and sliding gear 14 is connected with a joggle with planetary pinion 13, and track bar 16 is fixedly connected with eccentric bushing 12; Platen 1 is fixedly connected with track bar 16 respectively with platen 2 18; End cap 1 is fixedly connected with headstock 6 through seal ring 21 respectively with end cap 2 20, and platen 1 forms induction chamber 1 with headstock 6, and platen two forms induction chamber 2 23 with headstock; Pneumatic tube 24 1 ends are fixedly connected with air absorbing mouth 15, and the other end is fixedly connected with water inlet valve body 4.
When starting working, make the engagement of sliding gear and planetary pinion, motor rotates, and main shaft rotates; Eccentricity gear drives moving body and moves horizontally, thereby track bar is moved horizontally, and platen one is outwards moved, and strengthens induction chamber one space; Air-breathing from pump through pneumatic tube, when track bar moved round about, the gas of suction was discharged from relief opening, simultaneously; Platen two outwards moves, and strengthens induction chamber two spaces, and is air-breathing from pump through pneumatic tube, when track bar moves round about; The gas that sucks is discharged from relief opening, alternately changes two induction chamber volumes, and the gas in pump and the pneumatic tube is constantly discharged, and water is introduced in the pump; After treating the pump proper functioning, slide apart gear and planetary pinion quit work suction-exhaust device, and at this moment the driven by motor pump works on.
