Abstract
The utility model relates to an oil-line control system of an air compressor, in particular to an oil-way control system of a two-stage compression twin-screw air compressor. A relief valve, a one-stage host machine, a two-stage host machine, an oil air drum, a temperature control system, an oil filter, an oil stop valve, a pressure reduction valve and a distributor are sequentially and serially connected, a check valve is arranged on an oil-way between the two-stage host machine and the oil air drum, and a T oil port of the oil stop valve is communicated with the oil-way between the two-stagehost machine and the check valve. The oil-way control system has the advantages of compact structure, convenient mounting and more rational control.
Description
Technical field
The utility model relates to a kind of oil path control system of air compressor, particularly a kind of oil path control system of two stage compression screw air compressor.
Background technique
That screw compressor and piston compressor relatively have is simple in structure, few easy workout part, the repair cycle is long, volumetric efficiency is high, delivery temperature is low, to liquid hammer insensitive and can realization amount step-less adjustment etc. characteristics, so more and more being subjected to the user, screw compressor appreciates, need to realize artificial occasion in the national economy all departments and be widely used in, as the production of industrial products such as oil, chemical industry, light industry, medicine, the low temperature test of scientific research aspect, the air conditioning of heavy constructions such as the low temperature process of food, aquatic products, storage and public place etc.At present, for the control of the oil circuit of two stage compression screw air compressor, existing technology is generally split type connection control, exists control unreasonable, and contact is many, the problem that rate of fault is high.
The model utility summary of the invention
The utility model is exactly the deficiency in the background technique, provide that a kind of contact is few, control rationally, the oil path control system of novel two stage compression screw air compressor that rate of fault is low.
For achieving the above object, the oil path control system of the utility model two stage compression screw air compressor, comprise easing valve, the one-level main frame, the secondary main frame, barrel of oil and gas, pressure retaining valve, oil cooler, thermostat valve, oil strainer, stop fuel tap, reduction valve, distributor, pressure retaining valve is disclosed with oil gas and is connected, thermostat valve and oil cooler formation in parallel temperature control system, easing valve, the one-level main frame, the secondary main frame, barrel of oil and gas, temperature control system, oil strainer, stop fuel tap, reduction valve, distributor is connected successively, oil circuit between secondary main frame and the barrel of oil and gas is provided with safety check, stops the T hydraulic fluid port of fuel tap and is communicated with oil circuit between secondary main frame and the safety check.
For of the present utility model preferred, the e oil circuit of distributor is connected with the secondary main frame with the f oil circuit, and the b oil circuit of distributor, c oil circuit and d oil circuit are connected with the one-level main frame, and a oil circuit of distributor is communicated with oil circuit between easing valve and the one-level main frame.
The utility model is compared with background technique, has compact structure, easy for installation, and control is more reasonable.
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
