Hydroecium vacuum pump conventional at present substantially meets the needs of condenser water box evacuation, but by its design limit, vacuum pump is start by set date and closedown；The water system of vacuum pump needs Artificial Control, frequently results in unnecessary water content consumption；When turning back on after drain system fault, it is necessary to manual site starts, and waits for a period of time, and after drainage system normal operation to be determined, can leave。Therefore, the supporting vacuum pump of condenser water box can not meet automatization, intelligentized remote control requirements, maintains and safeguards very inconvenient。
Utility model content
The purpose of this utility model is to provide a kind of condenser water box vacuum pump, and to improve, existing hydroecium vacuum pump function is simple, automaticity is not high, water system needs human assistance control, uses the technical problems such as very inconvenient。
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of condenser water box vacuum pump, including base, controller, described base top is provided with vacuum pump drive motor, water ring vacuum pump, the output shaft of vacuum pump drive motor is connected with the power shaft of water ring vacuum pump, vacuum pump drive motor top is provided with air inlet pipe, air inlet pipe is connected with the feed side of Pneumatic butterfly valve, Pneumatic butterfly valve is connected with air compressor machine, the discharge side of Pneumatic butterfly valve is connected with one end of check-valves, the other end of check-valves is provided with air intake branch, air intake branch is connected with the air inlet of water ring vacuum pump respectively；The air vent of water ring vacuum pump is connected with steam-water separation case, and steam-water separation box top is provided with exhaustor, and steam-water separation bottom portion is provided with drain pipe；It is provided with water pump feed pipe in water ring vacuum pump side, water pump feed pipe is provided with moisturizing electromagnetic valve；Described air intake branch, water pump feed pipe are provided with Pressure gauge；Above-mentioned Pressure gauge, vacuum pump drive motor, Pneumatic butterfly valve, air compressor machine, moisturizing electromagnetic valve are all connected with controller。
As preferably, being additionally provided with air filter screen between described air inlet pipe and the feed side of Pneumatic butterfly valve。
As preferably, described water pump feed pipe being additionally provided with the moisturizing ball valve in parallel with moisturizing electromagnetic valve。
This condenser water box vacuum pump, by the pressure of air inlet pipe and water pump feed pipe is detected, when vacuum pressure exceedes setting value, hydroecium vacuum pump quits work, and closes Pneumatic butterfly valve, saves the consumption of electric power。When vacuum pressure is lower than setting value, opening Pneumatic butterfly valve, hydroecium vacuum pump is started working。Moisturizing electromagnetic valve and Pneumatic butterfly valve are linkages, and Pneumatic butterfly valve is failure to actuate, and moisturizing electromagnetic valve is also failure to actuate, and open Pneumatic butterfly valve, and moisturizing electromagnetic valve turns on and hydroecium vacuum pump is carried out moisturizing, and water consumption can significantly reduce。Check-valves can prevent the gas extracted out from returning hydroecium, and moisturizing ball valve can when moisturizing solenoid valve failure, manual moisturizing。The automatization level of this utility model hydroecium vacuum pump is higher, in that context it may be convenient to remotely controls and automatically controls, and saves and runs and maintenance cost, has good practical value。
