Summary of the invention
The purpose of this invention is to provide a kind of high speed drainage turbine synchronous discharging-suction pump that vacuum keeps function that has, this pump is being put under the machine stand-by state for a long time, can be at any time at the moment normal operation input, and start can be discharged medium.Be particularly suitable for away from the water source or be difficult for using under the condition of drainage.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
Have the high speed drainage turbine synchronous discharging-suction pump of vacuum maintenance function, comprise transfer pump, vacuum system and automatic control system, transfer pump has suction port and discharge opening, and tightness is connected with suction pipe between transfer pump and the vacuum system.Described vacuum system comprises vacuum machine and gas-liquid separator, between vacuum machine and the gas-liquid separator connecting tube is arranged, vacuum solenoid is housed on the connecting tube, the bottom of gas-liquid separator links to each other with suction pipe, suction pipe is connected with transfer pump by low sensors, and the horizontal position of low sensors is higher than the horizontal position center line of transfer pump, and high position sensor is installed on the gas-liquid separator, the horizontal position of high position sensor is higher than transfer pump, and the horizontal position of high position sensor is higher than low sensors.
Described transfer pump be horizontal centrifugal pump, vertical centrifugal pump and in open a kind of in the double suction pump.
The present invention has following advantage:
1, the present invention has the high speed drainage turbine synchronous discharging-suction pump that vacuum keeps function, comprises transfer pump, vacuum system and automatic control system, and tightness is connected with suction pipe between transfer pump and the vacuum system, and is provided with high position sensor and low sensors.The running of pump is by automatic controlling system, diversion time＜10S ' is better than National Fire Academy pump standard-required greatly, during as fire service pump or emergency bilge pump suction low level medium, install without self filling type, use first also to need not manually water filling or diversion in the pump.
2, the present invention has vacuum and keeps the high speed drainage turbine synchronous discharging-suction pump of function putting for a long time under the machine stand-by state, can be at any time at the moment normal operation input, and start can be discharged medium.Be particularly suitable for away from the water source or be difficult for using under the condition of drainage.
3, the present invention has vacuum and keeps the high speed drainage turbine synchronous discharging-suction pump of function can cancel the infrastructure of low zone pump room or head-tank, and volume is little, reduces investment outlay and takes up an area of, and maintenance is convenient.
