Abstract
The utility model discloses a kind of cantilever type water ring vaccum pump, comprise motor, the pump housing and impeller, pump housing right-hand member is fixedly connected with motor-driven end, motor-driven end is provided with rotating shaft, and impeller is positioned at pump body, and the pump housing is provided with suction port, a cavity is provided with in the pump housing, cavity is filled with filler, and cavity hatch place is provided with the gland matched, and the pump housing is provided with the elbow of water filling in cavity; Pump housing left end is installed with disk, and disk left end is installed with pump cover, and impeller is fixedly mounted on roller end by flat key bias, and disk is provided with relief opening.The impeller upper reaches that the utility model cold water flows to roller end by elbow and cavity forms water ring, water ring constantly reduces the high temperature that impeller produces in rotation process, the steam produced is along with the methane gas of releasing from mine is together from the relief opening discharge disk, can begin to make the methane gas of discharge remain at lower problem, avoid occurring potential safety hazard.
Description
Technical field
The utility model relates to a kind of vacuum pump of the methane gas extracted in coal mine, is specifically related to a kind of cantilever type water ring vaccum pump.
Background technique
Need to carry out draining to mine in process of coal mining, adopt the form vacuumized to carry out mine drainage more at present.General vacuum pump is when working long hours, the gas temperature of discharging can constantly raise, containing a large amount of methane gas in coal mine, what use general vacuum pump easily causes potential safety hazard when vacuumizing mine, need to take out a vacuum every one period of long period, working efficiency is low and safety reliability is low.
model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides one continually for a long time can vacuumize draining to mine, and working efficiency is high and can not cause the vacuum pump of potential safety hazard.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of cantilever type water ring vaccum pump, comprise motor, the pump housing and impeller, pump housing right-hand member is fixedly connected with motor-driven end, and motor-driven end is provided with rotating shaft, impeller is positioned at pump body, the pump housing is provided with suction port, is provided with a cavity, is filled with filler in cavity in the pump housing, cavity hatch place is provided with the gland matched, and the pump housing is provided with the elbow be communicated with cavity; Pump housing left end is installed with disk, and disk left end is installed with pump cover, and impeller is fixedly mounted on roller end by flat key bias, and disk is provided with relief opening.
As preferably, be provided with circular hole below the relief opening of disk, circular hole place is provided with the rubber ball valve matched.
As preferably, being provided with between disk and the pump housing can the mat of left and right adjusting.
As preferably, below motor, be installed with base.
the beneficial effects of the utility model are:
1, the elbow on the utility model pump housing is connected with water pipe, cold water in water pipe injects the cavity that then elbow enters pump body, the impeller upper reaches that cold water in last cavity flows to roller end forms water ring, water ring constantly reduces the high temperature that impeller produces in rotation process, the steam produced is along with the methane gas of releasing from mine is together from the relief opening discharge disk, can begin to make the methane gas of discharge remain at lower temperature, avoid occurring potential safety hazard.
2, be provided with circular hole below the relief opening on disk of the present utility model, circular hole and rubber ball valve are engaged in the pump housing when reaching exhaust pressure, and rubber ball valve is opened and automatically released by gas, can reduce the power consumpiton increased because air pressure is excessive.
3, the mat between the utility model pump housing and disk can left and right adjusting, thus adjustment impeller and the gap between the pump housing and disk, this gap determines gas in the pump housing by the size of losing in suction port to the relief opening flow process on disk.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, pump cover; 2, impeller; 3, disk; 4, suction port; 5, filler; 6, gland; 7, the pump housing; 8, motor; 9, rotating shaft; 10, flat key; 11, base; 12, cavity.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of cantilever type water ring vaccum pump, comprise motor 8, the pump housing 7 and impeller 2, the pump housing 7 right-hand member is fixedly connected with motor 8 driving end, and motor 8 driving end is provided with rotating shaft 9, it is inner that impeller 2 is positioned at the pump housing 7, the pump housing 7 is provided with suction port 4, is provided with a cavity 12, is filled with filler 5 in cavity 12 in the pump housing 7, cavity 12 opening is provided with the gland 6 matched, and the pump housing 7 is provided with the elbow be communicated with cavity 12; The pump housing 7 left end is installed with disk 2, and disk 2 left end is installed with pump cover 1, and impeller 2 is fixedly mounted on rotating shaft 9 end by flat key 10 bias, and disk 2 is provided with relief opening.Be provided with circular hole below the relief opening of disk 2, circular hole place is provided with the rubber ball valve matched.Being provided with between disk 2 and the pump housing 7 can the mat of left and right adjusting.Motor 8 is installed with base 11 below.
In implementation process, suction port 4 is connected with the pipeline of UNICOM's mine, elbow on the pump housing 7 is connected with water pipe, cold water in water pipe injects the cavity that then elbow enters the pump housing 7 inside, impeller 2 upper reaches that cold water in last cavity flows to rotating shaft 9 end forms water ring, water ring constantly reduces the high temperature that impeller 2 produces in rotation process, the steam produced is along with the methane gas of releasing from mine is together from the relief opening discharge disk 2, can begin to make the methane gas of discharge remain at lower temperature, avoid occurring potential safety hazard.Relief opening on disk 2 can be communicated with steam-water separator, and the drain opening that the elbow at this moment on the pump housing 7 can be communicated with steam-water separator is connected to form watering cycle to save water source.
Be provided with circular hole below relief opening on disk 2, circular hole and rubber ball valve are engaged in the pump housing 7 when reaching exhaust pressure, and rubber ball valve is opened and automatically released by gas, can reduce the power consumpiton increased because air pressure is excessive.
By the mat left and right adjusting between the pump housing 7 and disk 3, can adjust impeller 2 and the gap between the pump housing 7 and disk 3, this gap determines gas in the pump housing 7 by the size of losing in the relief opening flow process on suction port 4 to disk 2.
Above-mentioned mode of execution is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
