    1510493 Rotary compressors with cooling and sealing liquid flow control HOKUETSU KOGYO CO Ltd 15 Aug 1975 [2 Sept 1974] 34121/75 Heading F1N Liquid mixed with the gas delivered by a liquid cooled rotary compressor is separated immediately on its discharge to a chamber 10, the separated liquid being delivered by a pressure drainage pump 15 to a compressed gas receiving tank 17 for subsequent injection through a nozzle 25 into the working chamber(s) 1 at a rate determined by a regulator 24. The compressor is of the vane, screw, worm, centrifugal or turbine types. A pump 22 or the pressure in the tank 17 forces the liquid collected in the tank 17 through a cooler 20 and the regulator 24 to the nozzle 25. During full or partial unloading of the compressor a valve 7 is moved to throttle or stop the flow of gas entering the compressor through an intake opening 6. The resulting reduction in the delivery pressure causes a check-valve 11 to close. In order to reduce the power consumption during unloading the supply of liquid to the nozzle 25 is reduced by the regulator 24, a piston 37 thereof being movable by the valve 7 to a position restricting the flow area through the regulator. Gas in the tank 17 flows through a separator 27, a line 28 and a valve 29 to a point of use. The nozzle 25 may be located in a slide valve (34), Fig. 5 (not shown) movable by fluid-pressure to change the outlet flow area of the compressor.

    The invention relates to the field of compressor manufacturing, namely to compressor installations comprising rotary compressors with liquid cooling. A known compressor installation comprising a rotary compressor, the casing of which has a working and discharge chambers, the first of which is connected to a gas-liquid reservoir, and the second one is equipped with a discharge pipe connected to the last pipeline l3. This installation is closest to the invention of the technical essence and the achieved result. The disadvantage of this compressor installation is that in the operation of the compressor without load the working and discharge chambers are filled with liquid, as a result of which oil can form on the stopper, stop the compressor or break its working parts. The compressor, in this case, is forced to perform excess work, which leads to additional energy expenditure and makes rotational machines with liquid cooling less economical. The purpose of the present invention is to increase the efficiency of the compressor installation by reducing the power consumption. This goal is achieved by the fact that a pump is installed in the pipeline connecting the drain fitting to the reservoir, and a gas outlet is made in the discharge chamber located above the drainage nozzle and connected to the reservoir by a pipeline. This embodiment provides a reduction in power consumption due to the elimination of the harmful effects of the fluid, as well as the fact that the amount of fluid injected into the working chamber when operating without load can be significantly reduced. FIG. 1 shows a diagram of a compressor unit with a rotary lamellar compressor; in fig. 2 shows a plant with a rotary screw compressor; in fig. 3 shows an embodiment with a rotary screw compressor. In the diagrams, the path of passage of the fluid is shown by a solid line, the gas is shown in dotted lines.
    The compressor installation contains a rotary compressor 1, the casing of which has a working 2 and discharge 3 chambers, the first of which is connected to the gas-liquid reservoir 4 and the second is equipped with a discharge pipe 5 connected to the last pipeline b, on which the pump 7 is installed to force the liquid In the tank 4, In the injection chamber 3 there is a gas outlet 8, located above the discharge pipe 5 and connected by an additional gas pipeline 9 to the tank 4
    When the installation is in operation, the intake gas is compressed in the working chamber 2, mixed with the liquid supplied to the latter for cooling, sealing and lubrication, after which the gas-liquid mixture enters the injection chamber 3 where the gas is separated from the liquid. In the discharge chamber 3 an opening 8 is made gas release, located above the pipe 5 to drain the liquid and connected by pipeline 9 to the reservoir 4. The gas, freed from most of the liquid in the discharge chamber 3, enters the reservoir 4, is cleaned from small parts % of liquid and goes to the consumer. The liquid is pumped by means of the pump 7 to the tank 4, from where, after cooling, it again enters the working chamber 2 of the compressor 1.
    The opening in the injection chamber of a gas inlet that is connected to the reservoir with a tank ensures that gas and liquid move along separate pipelines with less resistance during the flow and discharge modes of the fluid, and the presence of a pump in the pipeline connecting the discharge nozzle to the reservoir allows
    reduce the back pressure and the power consumption of the compressor and prevent the formation of oil plugs leading to machine breakdown.
    Due to this improvement in the injection chamber, the use of an additional pipeline for gas, as well as the forced supply of liquid to the reservoir using a pump, the power consumed when the compressor is running without load can be reduced to 18% of the power consumed at full load, instead of 60% for rotary liquid-cooled compressor is usually of its type, and thus the efficiency of the entire compressor installation is increased. .
