Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail:
As shown in Figure 1, mine drainage multistage pump of the present invention can the pump-unit of having met an urgent need of automatic water supplement, comprises vacuum tank 107, level meter 106, diversion valve 108, water pump outlet valve 105, liquid jetting device 111, jet source valve 110, automatic controller 202 and supporting pipeline;
Described vacuum tank 107 bottom is provided with pump sump mouth, and top is provided with pump mouth, and pump sump mouth is connected with water pump 102 by water pump suction pipe 104, and pump mouth is connected with intake pipe 112, and described intake pipe 112 stretches into sump inside;
Between vacuum tank 107 and sump, be provided with aqueduct 109 and liquid jetting device 111, be provided with diversion valve 108 in the middle of aqueduct 109, liquid jetting device 111 is connected with jet source by jet source valve 110;
Between water pump 102 and vacuum tank 107, be provided with water pump outlet pipe 103, water pump outlet pipe 103 is connected with the upper end of vacuum tank 107, is provided with water pump outlet valve 105 in the middle of water pump outlet pipe 103,
Directly introduce the jet source of high pressure water as liquid jetting device from water pump main drainpipe 101;
Level detection sensor is installed at described vacuum tank 107 top, automatic controller is electrically connected with level detection sensor, can water level in on-line checkingi vacuum tank, when lower than moisturizing water level settings value, automatic controller control jet pump carries out moisturizing, vacuum tube water level is increased, ensures that vacuum tank 107 water level is higher than pump sump saliva position, makes water pump be in holding state at any time;
Vacuum tank 107 is special cylindrical; Blowdown access opening 113 is provided with bottom vacuum tank 107;
After mine drainage multistage pump runs, vacuum tank 107 can be full of water, but because the reasons such as pipeline reason or water pump itself leak can cause the water level of vacuum tank 107 more and more lower in water pump operation process, in order to prevent this water level lower than the height of suction sleeve in vacuum tank (107), now open jet source valve 110, jet source can be high pressure water in main drainpipe 101 or other high-pressure water, also can be pressurized air.Then diversion diversion valve 111 and water pump outlet valve 105 is opened, jet source produces jet effect by liquid jetting device 111, produce negative pressure at diversion valve 111 place pipeline, water will be sucked vacuum tank by vacuum tank intake pipe 112 by the water in sump by barometric pressure, reaches the effect of moisturizing;
