Problems solved by technology

Among them, the intake throttle has a wide range of adjustment, but the throttling resistance increases power consumption and exhaust temperature; although the connection of intake and exhaust pipes is simple and easy, it is equivalent to exhaust leakage, which increases energy consumption for no reason; compressor stop / start The adjustment is economical and is suitable for micro compressors. However, in addition to the need to configure a large-capacity gas storage tank, this method also has an adverse effect on the life of the motor and energy consumption; it is ideal to use speed adjustment, but an additional set is required. The frequency conversion speed regulation mechanism increases the cost of the compressor

Abstract

The present invention is method of stage regulating gas amount of single-screw compressor including mesh pair with screw bolt and planetary wheel and possessing sealed compressor body with gas inlet and gas outlet. The present invention features that the plunger solenoid valve is stepped installed on the compressor body with the top in the same cylindrical surface as the cylinder inner wall and is used to open the reflux port of the plunger solenoid valve, so as to return partial gas from inside the screw tank to the intake cavity of the compressor, alter the compression initiation time and realize the stage regulation in the gas amount of the single-screw compressor. The method may be adopted in both compressor and refrigerator, and is simple, feasible, efficient and easy in automatic control.

Description

technical field [0001] The invention belongs to the category of power machinery and chemical machinery, and relates to the regulation of a single-screw compressor, in particular to a step-by-step gas volume adjustment method of a single-screw compressor using a plunger electromagnetic valve. Background technique [0002] Since the single-screw compressor was put on the market in 1970, due to its simple structure, superior performance, convenient maintenance and good operation reliability, it has developed rapidly and has been widely used in the fields of gas power, chemical industry, construction, refrigeration and medicine. When the single-screw compressor is in use, due to the change of the gas demand, the compressor displacement is required to be adjusted accordingly. Single-screw refrigeration compressors (hereinafter referred to as refrigerators) generally use rotating rings or slide valves to adjust the cooling capacity. Both of these adjustment schemes complicate the ...
