Abstract
The utility model discloses an intelligent constant pressure control system for an industrial water pump. The system comprises the industrial water pump, and a pressure transmitter, a proportion integration differentiation (PID) controller, a frequency converter and a permanent magnet synchronous servo motor, which are sequentially in circuit connection, wherein the permanent magnet synchronous servo motor is used for driving the industrial water pump; and the pressure transmitter is arranged at a water outlet of the industrial water pump. The system also comprises a vacuum contactor connected in parallel with the frequency converter. According to the intelligent constant pressure control system for the industrial water pump, the industrial water pump is soft-started, starting current is low, impact on an impeller is avoided, and the output power of a motor of the water pump can be reasonably regulated according to water pressure.
Description
Technical field
The utility model relates to the electromechanical control field, is specifically related to a kind of intelligent constant voltage industrial water pump control system.
Background technique
One is responsible for relatively large industrial water industrial water pump, industrial water pump is that total head directly starts when starting at present, the electric current that starts is big, pump rotary speed rises fast, water pump vane is caused certain impact, after the hydraulic pressure of pump line net reaches the water pump upper limit, can produce negative pressure to water pump vane, after the termination of pumping, there is hammering in the water pump interior water of stall pipeline at once to impeller, the water pump vane frequent breakage, because water pump is that total head supplies water, the specified output of motor can not rationally be adjusted rotating speed according to manifold pressure electric energy is existed bigger waste, electric energy loss height.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of water pump soft start is provided, inrush current is little, and impeller is not had impact, and can rationally adjust the intelligent constant voltage industrial water pump control system of pump motor output power according to hydraulic pressure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of intelligent constant voltage industrial water pump control system, the pressure transmitter, PID controller, frequency variator, the permanent magnet synchronous servo motor that comprise industrial water pump and circuit connection successively, wherein permanent magnet synchronous servo motor is used for driving industrial water pump, and pressure transmitter is installed in industrial water pump water outlet place;
Also comprise the vacuum contactor in parallel with described frequency variator.
The beneficial effect that the utility model has is: industrial water pump is soft start when starting, and inrush current is little, and impeller is not had impact, the industrial water pump long service life, and motor speed can be adjusted automatically according to the pressure of supply water of water pump, and VFC is effectively energy-conservation.Vacuum contactor in parallel connection on the frequency variator disconnects vacuum contactor during proper functioning, in the time of need keeping in repair frequency variator, closed vacuum contactor can realize that the power frequency of permanent magnet synchronous servo motor drives, and does not influence the maintenance of frequency variator simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
1 pair of the utility model describes in further detail by reference to the accompanying drawings, so that the public grasps implementation methods of the present utility model better, the concrete scheme that the utility model is implemented is: intelligent constant voltage industrial water pump control system, comprise industrial water pump 1 and successively the pressure transmitter 2, the PID controller 3(model that connect of circuit be xb153-m181378), frequency variator 4, permanent magnet synchronous servo motor 5, wherein permanent magnet synchronous servo motor 5 is used for driving industrial water pump 1, and pressure transmitter 2 is installed in industrial water pump 1 water outlet place; Also comprise the vacuum contactor 6 in parallel with described frequency variator 4.Frequency variator 4 control permanent magnet synchronous servo motors 5 soft starts when needing to supply water, inrush current is little, permanent magnet synchronous servo motor 5 starts postindustrial water pump 1 and starts working, pressure transmitter 2 can be sensed the pressure in industrial water pump 1 outlet port, convert pressure signal to electrical signal and input to PID controller 3, PID controller 3 output control signals are given frequency variator 4,5 operations of frequency variator 4 control permanent magnet synchronous servo motors, permanent magnet synchronous servo motor 5 rotating speeds were low when pressure was high, permanent magnet synchronous servo motor 5 rotating speed height when pressure is low, realize accurate constant voltage control, permanent magnet synchronous servo motor 5 power consumptions reduce 30%-50%.
Above-described only is preferred implementation of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement.These also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
