Abstract
Discloses is a direct connection water ring vacuum pump. The direct connection water ring vacuum pump solves the problems that due to the working principle of a traditional vacuum pump, gas inhaled by the traditional vacuum pump can not contain gas which is corrosive, combustible and explosive and the like, and otherwise danger easily occurs. The direct connection water ring vacuum pump comprises a motor (11), wherein the motor is fixedly connected with a pump body (7), an output shaft (6) of the motor is installed in the pump body in eccentric mode, an impeller (4) is fixed on the output shaft through a flat key, a water blocking ring (12) is installed at the root of the output shaft, a liquid sealing ring (8) is installed in a concave cavity on a portion in the middle of the output shaft, which is connected with the pump body, the concave cavity is filled with padding (9), a stuffing press cover (10) covers the padding, a disk (1) is connected with the pump body through a cushion, a rubber ball (5) is installed on the disk, a pump cover (2) is connected with the pump body, and a water inlet pipe (3) is installed on the pump cover. The direct connection water ring vacuum pump is used on a vacuum pump.
Description
technical field:
the utility model relates to a kind of direct connection Nash hytor.
background technique:
traditional vacuum pump has corrosivity because playing a working principle, can not containing in the gas of suction, inflammable, explosive gas etc., otherwise easily causes danger.
model utility content:
the purpose of this utility model is to provide a kind of direct connection Nash hytor.
above-mentioned object realizes by following technological scheme:
a kind of direct connection Nash hytor, its composition comprises: motor, described motor is fixedly connected with the pump housing, the output shaft bias of described motor is arranged in the described pump housing, impeller is fixed on described output shaft by flat key, at described output shaft root, water retaining ring is installed, with the inner cavity of described pump housing joint, lantern ring for liquid seal is installed at described output shaft middle part, in described inner cavity, be filled with filler, Gland covers on described filler, disk is connected by mat with the described pump housing, on described disk, ball is installed, pump cover is connected with the described pump housing, on described pump cover, intake pipe is installed.
described direct connection Nash hytor, is provided with one group of circular hole on described disk, described ball is arranged on described circular hole place.
beneficial effect:
1. the method for work of this direct connection Nash hytor is as follows, impeller is arranged in the pump housing prejudicially, pumps up when moving, to the water that injects certain altitude in pump, in the time of vane rotary, water is subject to the effect of centrifugal force and forms a rotation water ring at pump housing inwall, and water ring lower inner surface and wheel hub are tangent, turn in journey in first half, water ring internal surface departs from wheel hub gradually, therefore between blade, form space and expand gradually, internal pressure, lower than ingress pressure, now sucks gas.Turn in journey later half, water ring internal surface is close with wheel hub gradually, and interlobate spatial volume is dwindled, and gas pressure is discharged from during higher than barometric pressure.So impeller is worked repeatedly, just intake-gas continuously of pump.Due in the course of the work, the compression of gas is isothermal, in the time that suction has corrosivity, inflammable, explosive gas, is difficult for causing danger.
2. motor output shaft bias of the present utility model is contained in the pump housing, impeller is fixed on axle with flat key, gap between impeller and pump cover and disk, adjusts with the mat between the pump housing and disk, is lost in pump thereby reduce gas by suction port in relief opening flows.
3. the utility model has a few row circular holes below disk upper air-vent, close with rubber ball valve, the effect in these holes is in the time that gas pressure between blade reaches exhaust power, before relief opening, just gas is emitted automatically, therefore reduces because of the excessive consumed power of gas pressure.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of direct connection Nash hytor, its composition comprises: motor 11, described motor is fixedly connected with the pump housing 7, output shaft 6 bias of described motor are arranged in the described pump housing, impeller 4 is fixed on described output shaft by flat key, at described output shaft root, water retaining ring 12 is installed, with the inner cavity of described pump housing joint, lantern ring for liquid seal 8 is installed at described output shaft middle part, in described inner cavity, be filled with filler 9, Gland 10 covers on described filler, disk 1 is connected by mat with the described pump housing, ball 5 is installed on described disk, pump cover 2 is connected with the described pump housing, intake pipe 3 is installed on described pump cover.
embodiment 2:
according to the direct connection Nash hytor described in embodiment 1, on described disk, be provided with one group of circular hole, described ball is arranged on described circular hole place.
Claims (2)
1. a direct connection Nash hytor, its composition comprises: motor, it is characterized in that: described motor is fixedly connected with the pump housing, the output shaft bias of described motor is arranged in the described pump housing, impeller is fixed on described output shaft by flat key, at described output shaft root, water retaining ring is installed, with the inner cavity of described pump housing joint, lantern ring for liquid seal is installed at described output shaft middle part, in described inner cavity, be filled with filler, Gland covers on described filler, disk is connected by mat with the described pump housing, on described disk, ball is installed, pump cover is connected with the described pump housing, on described pump cover, intake pipe is installed.
2. direct connection Nash hytor according to claim 1, is characterized in that: on described disk, be provided with one group of circular hole, described ball is arranged on described circular hole place.
