Abstract
The utility model discloses a water feeding system of a super dampening machine, which comprises a water tank, a water pump, a reducing valve, a flow meter, an electromagnetic valve, a nozzle, a controller and a frequency converter. The water pump is driven by a motor, the water tank, the water pump, the reducing valve, the flow meter, the electromagnetic valve and the nozzle are sequentially connected by pipelines, the frequency converter is electrically connected with the motor, and the flow meter, the electromagnetic valve and the frequency converter are electrically connected with the controller. The water feeding system omits a pneumatic diaphragm valve which operates unstably, and realizes automatic flow regulation by adopting a variable-frequency control mode instead, failure rate of the system is greatly reduced, and both stability and water feeding precision of the water feeding system are evidently improved. Further, the water tank does not need to work at the highest rotation speed all the time due to the fact that the frequency converter is adopted to control the motor of the water pump, accordingly the effect of energy conservation is realized, and the service life of the water pump is simultaneously prolonged.
Description
Technical field
The utility model relates to tobacco machine, is specifically related to a kind of automatic water-adding system of super damping machine.
Background technology
As shown in Figure 1, the cylindrical shell 20 of super damping machine is installed on the frame 30, and water-adding system 10 is that super damping machine supplies water.Existing water-adding system as shown in Figure 2, it comprises water tank 1, water pump 2, pressure-reducing valve 3, air bladder valve 4, flowmeter 5, magnetic valve 6 and the nozzle 7 that is connected successively, extract water by water pump 2 out from water tank 1, by pressure-reducing valve 3 steady pressures, measure the flow value of water outlet through flowmeter 5, and send the signal of telecommunication to controller, after comparing with setting value, the controller output signal of telecommunication is given air bladder valve 4, controls its open degree, reaches water yield automatic control purpose.
But according to practical effect, the shortcoming of this water-adding system is, the valve rod of air bladder valve 4 can produce corrosion after the use of a period of time, thereby influence valve rod travel, cause adding water unstable or amount of water does not reach requirement, and the adjustment of air bladder valve is cumbersome, and the back of breaking down influences production efficiency.In addition, in existing water-adding system, pump motor is to be operated in maximum speed always, and the unnecessary water that water pump is extracted out is got back in the water tank by return line again, not only waste energy, and water pump weares and teares easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of good stability, adds the high super damping machine water-adding system of crystal's degree, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of super damping machine water-adding system, comprise water tank, water pump, pressure-reducing valve, flowmeter, magnetic valve and nozzle, described water pump is by motor-driven, described water tank, water pump, pressure-reducing valve, flowmeter, magnetic valve and nozzle are connected successively by pipeline, also comprise a controller and a frequency converter, described frequency converter is electrically connected with motor, and described flowmeter, magnetic valve and frequency converter all are electrically connected with controller.
Preferably, the output of described water pump also is connected with water tank by water return pipeline.
Preferably, described controller is PLC or computer.
The beneficial effects of the utility model are, cancelled the air bladder valve of job insecurity, the mode by VFC of changing into realizes that flow regulates automatically, greatly reduces the fault rate of system, makes the stability of water-adding system and add crystal's degree all to have obtained improving significantly.In addition,, make water pump needn't be operated in maximum speed always, thereby reach energy-conservation effect, also improved the service life of water pump simultaneously owing to adopt frequency converter to control pump motor.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of super damping machine.
Fig. 2 is the schematic diagram of existing a kind of super damping machine water-adding system.
Fig. 3 is the schematic diagram of a kind of super damping machine water-adding system of the utility model.
The specific embodiment
As shown in Figure 3, in the super damping machine water-adding system of the utility model, water tank 1, water pump 2, pressure-reducing valve 3, flowmeter 5, magnetic valve 6 and nozzle 7 are connected successively by pipeline, constitute supply channel; The output of water pump 2 also is connected with water tank 1 by water return pipeline 11, can be back in the water tank 1 by the water that supply channel is unnecessary.
Wherein, water pump 2 is driven by motor 8, and motor 8 is connected with frequency converter 9 and is controlled by frequency converter 9.Also comprise a controller 40, controller 40 is such as being PLC or computer etc.Described flowmeter 5, magnetic valve 6 and frequency converter 9 all are electrically connected with controller 40, flow signal according to flowmeter 5 feedbacks, controller 40 can be controlled opening or closing of magnetic valve 6, and controller 40 can be controlled the rotating speed of motors 8 by frequency converter 9, thus the flow of control water pump 2.
The present invention reaches the purpose of controlling flow by the rotating speed of control pump motor, has formed up to fall the air bladder valve in system, and pump motor Frequency Converter Control, control signal are to take from the signal of telecommunication of original control air bladder valve opening.
Through after this improvement, amount of water all is significantly increased than before on stability and precision, and the rotating speed maximum of pump motor (secondary motor) also only needs about 30 hertz frequency to add the water requirement with regard to satisfying, and has improved the service life of water pump.
