Abstract
The utility model provides a double-stage refrigeration compressor unit device capable of avoiding oil leakage. The device mainly comprises an oil tank, a refrigerant storage tank, a low pressure stage screw compressor, an oil-gas separator, an oil cooler, a high pressure stage screw compressor, an oil-gas separator and a cooler. All the parts are connected according to a set connecting manner; an oil return pipe is designed to connect the low pressure stage compressor and cooler group equipment; the oil return pipe is communicated with a compressor shell side to converge return lines so as to ensure oil liquid levels of the oil-gas separators and effectively solve the problem of oil leakage; meanwhile, the device is less in equipment, simple in process and is convenient to manage.
Description
Technical field
The present invention relates to refrigeration compressor, particularly the cooling cycle system with helical-lobe compressor.
Background technology
The oily phenomenon of so-called race refers in compressor cooling cyclic process, in gs-oil separator, can occur without oily phenomenon, reason one is collected for oily in condenser, enter in evaporimeter but passed through expansion valve, oil adheres on evaporimeter heat exchange copper tube, the evaporation effect variation of evaporimeter, cause evaporimeter internal pressure on the low side, the suction superheat that simultaneously makes compressor very low making directly sucks refrigerant liquid, because now compressor row temperature is very low, oil still cannot separate with cold-producing medium, so vicious circle meeting all collects in evaporimeter all oil, compressor is because produce a thundering noise for shortage of oil, even unit oil eliminator warning and shutting down, reason two has all been come in condenser with exhaust for oil, lasting on the low side because of water temperature, cause oil all can collect in condenser, and it is stifled to make expansion valve that oil occur, and in evaporimeter, due to liquid supply rate deficiency, pressure starts reduction, until low pressure alarming is shut down.
Industry is in service, runs oily phenomenon obvious, and it is undesirable to enter from low pressure compressor the effect that gs-oil separator separates, and exists lubricating oil to be pressed into the phenomenon of hiigh pressure stage compressor, causes equipment to be difficult to long-term running and reduction of service life.
Summary of the invention
The object of the invention is to avoid or reduce and run oily phenomenon, overcoming the deficiencies in the prior art, providing a kind of avoiding to run oily two-stage refrigeration compressor bank device, this appliance arrangement is few, and flow process is simple, and convenient management efficiently solves the oily problem of running.
The present invention is mainly made up of oil tank (1), cold-producing medium storage tank (2), low-pressure stage helical-lobe compressor (3), gs-oil separator (4), oil cooler (5), hiigh pressure stage helical-lobe compressor (6), gs-oil separator (7), cooler (8), and its main connected mode is as follows:
Low-pressure stage compressor is connected with hiigh pressure stage compression stage to arrange and is formed Two-stage Compression unit, low-pressure stage compressor (3) exhaust outlet is connected with the oil-gas mixer entrance of gs-oil separator (4), the output of gs-oil separator connects oil cooler (5), refrigerant liquid is as the output of cooler, by filter with after oil pump, be connected with hiigh pressure stage compressor (6) jet, hiigh pressure stage exhaust outlet of compressor is connected with the entrance of gs-oil separator (7), gs-oil separator outlet connects cooler (8) entrance, cooler refrigerant steam (vapor) outlet is connected with hiigh pressure stage compressor air suction mouth, cooler (8) outlet is connected with low-pressure stage compressor oil cooler (5), form an oil return tube bank and import oil tank (1), connect into cooling cycle system by pipeline successively.
The shaft joint of low-pressure stage compressor, drive motors are arranged on oil eliminator, the shaft joint of hiigh pressure stage compressor, drive motors are arranged on oil cooler, enter the cooler after gs-oil separator through hiigh pressure stage compressor, draw an oil return pipe and connect low-pressure stage compressor cooler group equipment, oil return pipe is connected return wire is merged together with compression set shell side, and circulation, the oil liquid level of guarantee gs-oil separator.
Brief description of the drawings
Fig. 1 is connection diagram of the present invention.
In figure, the meaning of each numbering representative is as follows
1: oil tank; 2: cold-producing medium storage tank; 3: low-pressure stage helical-lobe compressor; 4: gs-oil separator; 5: oil cooler; 6: hiigh pressure stage helical-lobe compressor; 7: gs-oil separator; 8: cooler;
