Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1:
As shown in Figure 1, having vacuum keeps the high speed drain turbine synchronous discharging-suction pump of function to include delivery pump 1, vacuum equipment 2 and automatic control system, and the running of the described high speed drain turbine synchronous discharging-suction pump with vacuum holding function is by automatic controlling system.Between delivery pump 1 and vacuum equipment 2, air-tightness connects suction tube 5.
Described delivery pump 1 is vertical centrifugal pump, and delivery pump has suction inlet 13 and discharge opening 14.
Described vacuum equipment 2 includes vacuum machine 26 and gas-liquid separator 27.A connecting tube 28 is had between vacuum machine 26 and gas-liquid separator 27, equipped with a vacuum solenoid 29 in connecting tube 28, the bottom of gas-liquid separator 27 offers an air entry, this air entry is connected with suction tube 5, the other end of suction tube 5 is connected with delivery pump 1 by low sensors 11, the horizontal level of low sensors 11 is slightly above the horizontal level centrage of delivery pump 1, one high position sensor 210 is installed on gas-liquid separator 27, the horizontal level of sensor 210 is higher than delivery pump 1, and the horizontal level of high position sensor 210 is higher than low sensors 11.
Operation principle:
Before starting first, pass through automatic controlling system, first open vacuum solenoid 29, restart vacuum equipment 2, it is evacuated to vacuum by instantaneous in the pump chamber of delivery pump 1, when in pump, vacuum reaches certain value, medium is at atmosheric pressure in the pipeline entrance pump being connected with delivery pump 1, after being filled with medium in pump, medium enters gas-liquid separator 27 through suction tube 5, medium liquid level after gas-liquid separation rises to high position sensor 210 predeterminated position, high position sensor 210 transmits signals to automatic control system, automatic control system sends command signal, now having vacuum keeps the high speed drain turbine synchronous discharging-suction pump of function automatically into putting machine resting state.If pump and pipe-line system leak in putting machine alternate processes for a long time, the liquid level in the pump chamber of vacuum equipment 2 and delivery pump 1 is caused to decline, when it drops to the predeterminated position of low sensors 11, low sensors 11 transmits signals to automatic control system, automatic control system sends command signal and automatically starts vacuum equipment 2, and intrasystem liquid level returns to high position sensor 210 predeterminated position.There is the high speed drain turbine synchronous discharging-suction pump of vacuum holding function under putting machine resting state, can be at any time at moment normal operation input.
Embodiment 2:
As in figure 2 it is shown, described delivery pump 1 is centrifugal pump of horizontal axis, remaining is with embodiment 1.
