Abstract
The invention relates to a cooling frequency-conversion control system of a compressor, comprising a controller, a frequency converter, a temperature sensor, a cooling motor and a cooler. The cooling frequency-conversion control system of the compressor is characterized in that the cooling motor is controlled to control operating temperature with proper load speed through the frequency converter according to the actual operating loads of the compressor, therefore the purpose of energy saving is achieved.
Description
Technical field: compressor cooling frequency-changing control system is a kind of control system to the compressor operating temperature.
Background technique: at present, air compressor cooling control mode be thermostat valve (claiming thermostat again) control the compressor operating temperature and cooling motor be all the time operate at full capacity constant.When running temperature is low, the 1-thermostat valve with A, B open A, D closes, cold oil exports to working connection to the 3-cooler to C-through thermostat valve by A, finishes major cycle, no matter and at this moment cold oil walk cooler, cooling motor is operated at full capacity all the time.
Summary of the invention: compressor cooling frequency-changing control system is, controller is monitored and fed back to the running temperature of compressor to be handled, the frequency variator of control cooling motor, according to the suitable load speed of compressor actual motion load control cooling motor, to reach purpose of energy saving, this moment, cold oil all cooled off through supercooler.
Description of drawings: Fig. 1,1-thermostat valve 2-cooling motor 3-cooler A-thermostat valve import B-thermostat valve outlet C-thermostat valve outlet diagram 2, the outlet of 1-controller 2-frequency variator 3-cooling motor 4-cooler 5-temperature transducer A-thermostat valve import B-thermostat valve
Embodiment: insert controllable frequency converter in the circuit of cooling fan, cancelled thermostat valve, temperature transducer is installed in the working connection system, and the feedback temperature signal is delivered to compressor cooling frequency-changing control system.When the oil temperature is low, the signal of temperature transducer feedback cools off frequency-changing control system to compressor, make it export corresponding low-frequency voltage, make cooling fan place low-speed running even stall, rising along with the oil temperature, temperature transducer feeds back signal to compressor cooling frequency-changing control system, make it export corresponding high-frequency voltage, cooling fan is worked under corresponding rotating speeds, the oily temperature of working connection operation can be set by the controller buttons of variable frequency convertor, thereby cooling fan can be in different temperature, environment and working load are adjusted rotating speed automatically by setting running temperature, reach the purpose of economize on electricity.
