6, termination of pumping voluntarily when unmanned water starts when people's water is arranged voluntarily.
7, vacuum tank can satisfy the water demand of user in the short time power failure process in the power failure process.
Description of drawings
Fig. 1 is the piping arrangement of a kind of deep well pump stable voltage frequency conversion of the utility model water system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.A kind of deep well pump stable voltage frequency conversion water system, described deep well pump stable voltage frequency conversion water system comprises electronic control cabinet 1, water storage well and is arranged on deep water pump 6 in the water storage well, it is characterized in that: described deep well pump stable voltage frequency conversion water system also is provided with vacuum tank, described vacuum tank is arranged on deep water pump 6 and draws water on the pipeline and the position between the user, described electronic control cabinet 1 and deep water pump 6 and vacuum tank and be arranged on the sensor electrical that deep water pump 6 draws water on the pipeline and be connected.
Describedly be arranged on the sensor that deep water pump 6 draws water on the pipeline and comprise vacuum tank pressure sensor, water storage well pressure sensor, user's main-supply pressure sensor, described vacuum tank pressure sensor is arranged on the vacuum tank, water storage well pressure sensor is arranged near the deep water pump 6, user's main-supply pressure sensor is serially connected on user's water supply line, and above-mentioned 3 kinds of sensors all are electrically connected with electronic control cabinet 1.
Described vacuum tank inside is vacuum tank inner balloon structure, when deep water pump 6 pipeline that draws water is opened and to be made, deep water pump 6 extracts the supply user with the water in the water storage well and supplies water for vacuum tank simultaneously, the vacuum tank internal pressure reaches the closed electromagnetic valve that setting is arranged on the vacuum tank bottom, when water in the water storage well is not enough, the electromagnetic valve that is arranged on the vacuum tank bottom is opened, and is that the user supplies water by vacuum tank.
When deep well pump stable voltage frequency conversion water system normally starts, deep well pump is to the water supply network pressurized water supply, simultaneously to the vacuum tank moisturizing, when 3 water inlets of the vacuum tank inner balloon in the vacuum tank 2 are squeezed, the vacuum tank pressure inside improves gradually, stops into water when pressure reaches vacuum tank initial setting pressure.In case when the system blackout deep well pump was out of service, the pressure in the pipe network reduced rapidly, when the pressure in the pipe network was lower than pressure in the vacuum tank, vacuum tank 2 inner balloon 3 in the vacuum tank 2 began water squeezing outward, and the water in the vacuum tank 2 supplies water to water supply network.
Be provided with the frequency conversion control circuit board in the described switch board, be provided with pressure regulator, programmable logic controller.
Pressure sensor converts the ductwork pressure signal to the signal of telecommunication and delivers to pressure regulator, the pressure requirement of setting according to the user by pressure regulator again, error to detected value, setting value is carried out computing, and operation result delivered to enrolled in the programmable logic controller of program in advance, by the programmer output regulation signal go to control AC converter startup, stop, simultaneously frequency converter carries out speed governing to water pump again according to the different frequency of margin of error output of detected value and setting value.1 is that electronic control cabinet, 2 is that vacuum tank, 3 is that vacuum tank inner balloon, 4 is that pressure meter, 5 is that user's main-supply pressure sensor, 6 is deep water pump among the figure.
This apparatus control system part is mainly by frequency converter, PLC programmable logic controller, the constant pressure frequency conversion speed governing that PID pressure regulator three parts realize.The equipment chief component is made up of deep well pump, vacuum tank 2, switch board, pressure sensor.The equipment operating principle is: the vacuum tank pressure sensor, water storage well pressure sensor, convert the ductwork pressure signal to the signal of telecommunication and deliver to pressure regulator, the pressure requirement of setting according to the user by pressure regulator again, to detected value, the error of setting value is carried out computing, and operation result delivered to enrolled in the programmable logic controller of program in advance, go to control the startup of AC converter by the programmer output regulation signal, stop, frequency converter carries out speed governing to water pump again according to the different frequency of margin of error output of detected value and setting value simultaneously, thereby the deep water pump motor is realized loop control, reach from motion tracking, constant voltage, the purpose that variable supplies water.Satisfy life, produce the requirement of hydraulic pressure, the water yield.
Equipment moves automatically, and water pump is devoted oneself to work automatically, the pressure that sets according to adjuster according to concrete construction needs by adjuster and sensor control of pump frequency conversion closed loop constant-pressure operation.When changing, automatic frequency-conversion is regulated the pressure operation, to realize that constant pressure water supply satisfies the requirement of user's water by adjuster and sensor as urban water demand.So just make system do the operation of closed loop stable working according to the given adjusting parameter setting pressure of adjuster.Thereby reach the purpose of constant pressure water supply.
Increase the micro computer timed unit by switch board, equipment can be set at 24 hours whole days and supply water, and also can be set at multi-period water supply every day, but do energy conservation like this.
When equipment normally started, the deep well pump frequency conversion was to the water supply network pressurized water supply, simultaneously to vacuum tank 2 moisturizings.When 3 water inlets of the vacuum tank inner balloon in the vacuum tank 2 were squeezed, vacuum tank 2 pressure inside improved gradually, stop into water when pressure reaches vacuum tank 2 initial setting pressure.When in case the system blackout deep well pump is out of service, pressure in the pipe network reduces rapidly, when the pressure in the pipe network is lower than pressure in the vacuum tank 2, vacuum tank inner balloon 3 in the vacuum tank 2 begins water squeezing outward, water in the vacuum tank 2 supplies water to water supply network, satisfy the water requirement of user's short time, when ductwork pressure equated with the pressure of vacuum tank 2, vacuum tank 2 stopped outside water supply.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
