Изобретение относитс к области компреосоростроени .This invention relates to the field of composting.
Известна система смазки винтового компрессора со встроенным электродвигателем, содержаща маслосборник с насосом, подаю- шим по трубопроводу через маслоотделитель масло на подшипники компрессора и электродвигател и на впрыск ij .A lubrication system for a screw compressor with an integrated electric motor is known, which contains an oil sump with a pump, supplying oil through bearings through the oil separator to the bearings of the compressor and electric motor and to the injection ij.
Однако в такой системе смазки масло, идущее на смазку подшипников и стекающее на Сторону всасывани , забираетс компреосором вместе с парами хладагента, котсфые подогреваютс маслом, что снижает КПД компрессора.However, in such a lubrication system, the oil that goes into bearing lubrication and flows down to the suction side is taken by the compressor along with refrigerant vapor, which is heated by oil, which reduces the efficiency of the compressor.
Наиболее близкой к предлагаемому изобретению по технической сущности и дости гаемому результату вл етс система смаз« ки винтовою компрессора, содержаща маслоотделигель на линии нагнетани , маслосборник в полости всасывани , соединенный через поплавковый и обратный клапаны с насосом С2.Closest to the proposed invention in its technical essence and the achieved result is a lubrication system with a compressor screw, which contains an oil drain on the discharge line, an oil sump in the suction cavity, which is connected through a float valve and a check valve to a C2 pump.
В этой системе смазки масло из полости всасывани забираетс насосом, дл привода In this lubrication system, oil is drawn from the suction cavity by a pump, for driving
которого затрачиваетс дополт-гельна мощность электродвигател .the power of the electric motor is spent.
Целью изобретени вл етс снижение затрат энергии на привод насоса.The aim of the invention is to reduce the energy costs for driving the pump.
Достигаетс это тем, что между обратным клапаном и насосом установлен эжектор , рабочее сопло которого подсоединено к маслосборнику на линии нагнетани .This is achieved by installing an ejector between the check valve and the pump, the working nozzle of which is connected to the oil sump on the discharge line.
На чертеже схематично изображена система смазки винтового компрессора.The drawing schematically shows a lubrication system for a screw compressor.
Система смазки винтового компрессора состоит из маслоотделител 1 на линии нагнетани 2, маслосборника, 3 в полостиThe lubrication system of a screw compressor consists of an oil separator 1 on the discharge line 2, an oil sump, 3 in the cavity
4всасывани , который через поплавковый4 suction which through float
5и обратный 6 клапаны соединен с насосом 7. Между обратным клапаном 6 и «асосом 7 установлен эжектор 8, рабочее сопло 9 которого подсоединено к маслосборнику 3, на линии нагнетани 3.5 and the check valve 6 are connected to the pump 7. Between the check valve 6 and the pump 7, an ejector 8 is installed, the working nozzle 9 of which is connected to the oil sump 3, on the discharge line 3.
Насосом 7 масло подаетс по йинии нагнетани 2 и поступает на впрыск в компрессор , а также на смазку подшипников компрессора и электродвигател . Часть мап«. ла, идуща на впрыск, вместе с хладагиитом нагнетаетс в К4аслоогдейигель 1, вBy pump 7, the oil is supplied through the injection line 2 and is fed to the injection into the compressor, as well as to the lubrication of the bearings of the compressor and the electric motor. Part of the MAP. " la, going to the injection, together with the coolagite is injected into K4 sllogedeygel 1,
