Description
Technical field:
The utility model relates to a kind of spray technique field: particularly a kind of automatic water jetting mist pumping plant.
Background technology:
The colliery digger produces a large amount of dust, and the dust that sieving machine produces can produce harm to the personnel of operation area, and the effective ways of the dust that the cancel job district produces are, atomized water spray is carried out in the operation area, make the dust landing and avoid to around diffusion.Because varying in size of the dust concentration that the operation area produces, dust granules need just can reach desirable effect with different water smoke.
Summary of the invention:
The purpose of this utility model provides a kind of spray amount can regulate a kind of easily automatic water jetting mist pumping plant.The technical scheme that realizes the utility model purpose is a kind of automatic water jetting mist pumping plant, comprise water pump and fog-spray nozzle, it is characterized in that: the atomized water spray pumping plant is provided with hydraulic control device, this hydraulic control device is made up of intelligent SPWM generator and PID controller, the PID controller has two minimum and maximum water pressure value input port D02 and D03, the V12 port of PID controller is connected with pressure sensor on the water pump water outlet pipeline, the V01 of this PID controller, the SET1 of V02 port and intelligent SPWM generator, SET2, SET3 is connected with the frequency controller circuit through decoding circuit with the SET4 port, PWM generator in the intelligence SPWM generator is connected with described frequency controller circuit respectively, and the RPHT and the RPHB that pass through intelligent SPWM generator, YPHT and YPHB, BPHT is connected with electric power electronic module with the BPHB interface, the two-phase input of this electric power electronic module is connected with the output that the liquid device is put in order in the rectification on the three-phase alternating current source circuit, and the three-phase output end of this electric power electronic module is connected with pump motor.The utility model has the remarkable advantage of automatic adjusting spray amount compared with the prior art.
Description of drawings:
Fig. 1 is a block system schematic diagram of the present utility model, and Fig. 2 is control principle figure of the present utility model.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is described in detail, the atomized water spray pumping plant that the dust that the dust in the digging operation district, colliery of solution at present or the operation of sieve powder produce adopts the harm of operating personnel and environment generation, because the dust granule size difference that produced by operation, perhaps the variation of hydraulic pressure all can make the removal ability difference of institute's atomized water spray to dust, the situation (the big or small density of water smoke) that changes the water smoke of ejection when needs needs manual change's hydraulic pressure, changes shower nozzle etc., complicated operation, even need stop operation.For addressing the above problem, in the pipeline of the utility model between storage tank 3 and fog-spray nozzle 4 pressure sensor is set, the motor 1 that drives water pump 2 can be a fire-proof motor, this fire-proof motor is applicable to the colliery digging area, avoids causing gas explosion accident.
In conjunction with Fig. 2 the Automatic Control Theory of atomized water spray pumping plant of the present utility model is described, the port V12 of PID controller (model is IPC301) is connected with sensor, the D02 of PID controller, the D03 port is the maximum pressure value of hydraulic pressure setting and the input port of minimum pressure values, the port V01 of PID controller, (model is SA866DE to V02 with intelligent SPWM generator respectively, manufacturer is a MIPEL semiconductor company) in the port (SET1 of frequency control circuit, SET2, SET3, SET4) connect, PWM generator in the intelligence SPWM generator control circuit is connected with the intelligent electric power electronic module with the said frequencies controller respectively, one end of this intelligent electric power electronic module is connected with rectification fluid strainer on the three-phase alternating current source circuit, and the three-phase alternating-current supply of its other end is connected with the motor M that drives water pump.The control principle of above-mentioned control circuit is, atomized water spray index according to the operation area requirement, maximum with the hydraulic pressure set, minimum of a value is input in the PID controller, the actual hydraulic pressure power value that this setup pressure value and sensor record compares, if during greater than prescribed limit, motor is controlled through the intelligent electric power electronic module through frequency control circuit in the intelligent SPWM generator control circuit and the certain frequency of PWM generator computing output, make motor accelerate or reduce rotating speed, adjust the hydraulic pressure that water pump comes out, thereby obtain desired atomized water spray situation, realized the closed cycle of atomized water spray.
