Description
Technical field
The utility model relates to technical field of electromechanical control, is specifically related to a kind of industrial oil mist purifying control system.
Background technology
Industrial oil mist cleaning equipment is a kind of industry environmental protection equipment; be arranged on the machining equipments such as all kinds of lathe such as CNC machining center, grinding machine, lathe or cleaning machine; the environmental pollutants of the mist of oil produced in machining, water smoke, dust etc. is collected and purified, reaches the object purifying air, protect workman healthy.The motor of existing industrial oil mist cleaning equipment adopts star triangle start usually, and when adopting star triangle start mode, current characteristics is fine, and torque characteristics is poor, adopt the industrial oil mist cleaning equipment of this Starting mode to have suction uncontrollable, noise is large, the shortcoming that power consumption is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide the industrial oil mist purifying control system that a kind of negative pressure is constant, noise is little, energy consumption is low.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Design a kind of industrial oil mist purifying control system, comprise at least one group of centrifugal blower and frequency converter, wherein the connection of one group of centrifugal blower and frequency converter and control mode are: described frequency converter one end is connected with circuit breaker Q F1, and the other end connects by contactor KM11 is corresponding with described centrifugal blower; Described frequency converter is controlled by a Closed Loop Control Unit, described Closed Loop Control Unit comprises the contactor KM12 and thermal overload relay KH11 that are in series, described contactor KM12 is connected between described frequency converter and circuit breaker Q F1, and described thermal overload relay KH11 is connected between described centrifugal blower and contactor KM11.
Preferably, also comprise the wind pressure sensor for measuring airduct negative pressure, described wind pressure sensor is corresponding with described frequency converter to be connected.
Preferably, described contactor KM11, KM12 are LC1D32M7C type A.C. contactor.
Preferably, described thermal overload relay KH11 is LRD21C type thermal overload relay.
Preferably, described circuit breaker Q F1 is IC65H3PD32 type miniature circuit breaker.
Preferably, described centrifugal blower and frequency converter are four groups, the close-loop control mode of the structure often organized, connected mode and frequency converter all with above-mentioned one group identical.
The beneficial effects of the utility model are:
Frequency converter adopts closed-loop control, and closed-loop control is combined by contactor and thermal overload relay, forms a magnetic starter, protects and overladen circuit may occur; Measure airduct negative pressure with wind pressure sensor, then testing result is converted to electrical signal transfer to frequency converter, then control the rotating speed of frequency converter by Closed Loop Control Unit, the object that negative pressure is constant can be reached, decrease noise simultaneously, greatly save the consumption of electric energy.
