Technical Field
The utility model belongs to the technical field of centrifugal compressor, concretely relates to centrifugal compressor lubricating oil cooling system.
Background
Centrifugal compressors, also known as turbine compressors, are used primarily to compress gas to increase pressure for gas delivery or to meet gas customer process requirements.
In the working process of the centrifugal compressor, each friction pair needs to be lubricated and cooled so as to reduce mechanical wear, power consumption and noise. The existing centrifugal compressor lubricating oil cooling system on the market is a partial cooling mode. That is, only a part of the pressurized lubricating oil sucked from the oil tank by the oil pump is cooled by the cooler and sent to each lubricating point, and the other part (even most part) of the pressurized lubricating oil directly overflows through the pressure regulating overflow valve and returns to the oil tank due to the control of the oil supply pressure. The disadvantages of this are: 1. the directly overflowed lubricating oil is not only not cooled, but also obtains energy through the process of pressurizing by an oil pump. 2. The lubricating oil flowing through the cooler is reduced by the overflow, and the flow rate in the cooler is reduced, thereby causing a reduction in the heat exchange effect. 3. When the oil cooling effect is poor, the user may misunderstand that the cooling area is small and request to increase the cooling area, and the cooling effect is worse because the flow rate is lower. 4. The user may also increase the amount of cooling water used to enhance the heat exchange effect, thereby consuming more cooling water. 5. The oil temperature of the oil tank rises due to the fact that only part of the lubricating oil is cooled, and therefore the lubricating oil smoke is increased.
In order to solve centrifugal compressor lubricating oil adoption drawback of partial cooling mode, the utility model discloses adopt the full cooling mode with centrifugal compressor lubricating oil cooling system, be about to all sending to each moist point after the oil cooler cooling with the overflow valve regulated pressure again after the pumping lubricating oil to reduce oil tank lubricating oil temperature effectively, reduce the oil mist and generate. Meanwhile, the cooling effect of the oil cooler is improved, and the consumption of cooling water is reduced. The purposes of protecting equipment, saving energy, reducing consumption and improving environmental protection are achieved.
