Position rises, and negative pressure compensating exhaust valve closure, the pressure of supply water of municipal network water supply is directly superimposed upon pump entrance, and water pump need to only carry
For the power needed for supplement insufficient pressure part.The Chinese utility model of Application No. 201320119961.5 discloses one kind
Super-silent non-negative pressure water-supply installation, including the pot with no negative pressure of water inlet pipe is connected with, the feedwater being connected by pipeline with pot with no negative pressure
Pump, the outlet pipe being connected with feed pump, the pressurized tank being connected to by tee pipe fitting on outlet pipe, and with pot with no negative pressure, give
Water pump, outlet pipe are all connected with and the internal switch board for being provided with control system.Above prior art non-negative pressure unitized can not supply
Wetting system when unit is waken up oepration at full load, break halting problem by the system erroneous judgement caused by abrupt pressure reduction in pot with no negative pressure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of secondary water-supply complete set of equipments pot with no negative pressure and enters water control
Device processed, it can solve non-negative pressure unitized supply equipment when unit is waken up oepration at full load, because pressure is dashed forward in pot with no negative pressure
System erroneous judgement caused by drop is broken halting problem.
The technical solution of the utility model is：A kind of secondary water-supply complete set of equipments pot with no negative pressure inlet control device, including
Pot with no negative pressure and switch board, pot with no negative pressure are provided with water inlet and measuring instrument installation screw thread mouth, and pot with no negative pressure bottom is provided with out
The mouth of a river, liquid level gauge is installed in pot with no negative pressure, liquid level gauge upper end is located at measuring instrument installation screw thread mouth, liquid level gauge connection control
Cabinet.
The secondary water-supply complete set of equipments pot with no negative pressure inlet control device also includes the change of connection pot with no negative pressure delivery port
Frequency modulation speed water pump assembly, frequency conversion speed adjusting pump unit connection switch board.
The switch board is frequency-conversion control cabinet.
Vacuum suppresser, vacuum suppresser connection switch board are connected with the top of the pot with no negative pressure.
The water inlet of the pot with no negative pressure is provided with entering water electromagnetic valve, entering water electromagnetic valve connection switch board.
The pot with no negative pressure bottom is provided with sewage draining exit, and blowoff valve is provided with sewage draining exit.
The secondary water-supply complete set of equipments pot with no negative pressure inlet control device also includes the fluid level transmitter of connection liquid level gauge,
The liquid level gauge connects switch board by fluid level transmitter.
The utility model replaces pressure transmitter in pot with no negative pressure using liquid level gauge, and control system is by directly reading liquid level
Count, judge whether water inlet is abnormal, avoid in tank body that system erroneous judgement is broken caused by pressure jump.The utility model solves nothing
Negative pressure unitized supply equipment is when unit is waken up oepration at full load, because abrupt pressure reduction causes system erroneous judgement is disconnected to stop in pot with no negative pressure
The problem of machine.
