Abstract
The invention discloses a control system for an air heater and belongs to the technical field of fan equipment. The air heater comprises a temperature sensor and an air quantity sensor, wherein the temperature sensor is connected with a temperature control interface end of a frequency converter; the air quantity sensor is connected with an air quantity control interface end of the frequency converter; a switch is connected to a start interface end of the frequency converter; a signal output end of the frequency converter is connected with electric heating tubes and a time relay; a contact end of the time relay is connected with a motor in series; multiple electric heating tubes are connected in parallel. According to the control system disclosed by the invention, the problem that as an existing air heater is single in control function, the temperature and the air outlet volume cannot be simultaneously controlled can be solved.
Description
Technical field
The present invention relates to Fan Equipment technical field, the air-heater of especially a kind of controllable temperature and control air output size.
Background technology
Air-heater is widely used a kind of drying equipment, existing a kind of air-heater includes the heater and air blast that are connected with power supply, the temperature sensor that relay is connected with heater is provided with at the air outlet place of air-heater, during work, connect blower power supply, air blast blow air in heater, make air from helical form heating wire, outside is evenly passed through, the heat produced after heating wire energising carries out heat exchange with the cold air passed through, thus the wind-warm syndrome of air outlet is raised, when air outlet place, temperature rises to predetermined value, temperature sensor and transmission of signal are to relay, relay is disconnected, thus cut off the connection of heater and power supply.But it is more single that this air-heater also exists controlling functions, the problem of air output during control temperature, can not be controlled simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of air-heater control system, and it is more single that this air-heater control system can solve existing air-heater controlling functions, can not control the problem of air output during control temperature simultaneously.
In order to solve the problem, the technical solution adopted in the present invention is: this air-heater control system, includes the temperature sensor be connected with the temperature control interface end of frequency converter and the air flow sensor be connected with the Boiler pressure control interface end of described frequency converter; The startup interface end of described frequency converter is connected with switch; The signal output part of described frequency converter is connected with the time relay with electric heating tube, and the tip side of the described time relay is connected in series mutually with motor.
In above-mentioned air-heater control system technical scheme, technical scheme can also be more specifically: described electric heating tube is many that are connected in parallel.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to being provided with frequency converter, and frequency converter temperature control interface end connects temperature sensor, and the Boiler pressure control interface end of frequency converter connects air flow sensor; Therefore the frequency converter live signal that can transmit according to temperature sensor and air flow sensor, the adjustment heating-up temperature of electric heating tube and the size of air output in good time, the present invention has not only saved the safety that the energy more protects equipment.
2, owing to being connected with the time relay between the signal output part and motor of frequency converter, when switching on power, electric heating tube first heats, and the time relay makes electric motor starting suspend a period of time, when after air heat in air-heater, restarts motor and hot gas is blown out; Its energy consumption is low, has saved the energy.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of air-heater control system shown in Fig. 1, includes the temperature sensor 2 be connected with temperature control interface end b with the temperature control interface end a of frequency converter 1; Boiler pressure control interface end c and the Boiler pressure control interface end d of frequency converter 1 are connected with air flow sensor 3; Startup interface end e and the startup interface end f of frequency converter 1 are connected with switch 7; The signal output part of frequency converter 1 is connected with the time relay 6 with electric heating tube 4, and the tip side of the time relay 6 is connected in series mutually with motor 5; Electric heating tube 4 is many of being connected in parallel.During work, electric heater for heating, time relay time delay connected motor power after 15 minutes, and now motor makes hot gas blow out; The live signal that frequency converter transmits according to temperature sensor and air flow sensor, in good time the adjustment heating-up temperature of electric heating tube 4 and the size of air output.The present invention has not only saved the safety that the energy more protects equipment.
