Problems solved by technology
The long-term oil circulation leads to delays in the single-machine test run of the new device, and the inability to produce products as soon as possible, which not only affects the economic benefits of the owner, but also increases the construction cost of the construction unit
Therefore, in view of the long oil circulation time and low efficiency of the compressor unit, it is necessary to improve the oil circulation technology

The invention discloses an oil circulation method of a compressor unit. An outer circulation system is used for finishing the outer circulation; after the outer circulation is qualified, the inner circulation is performed; an inner circulation system is used for performing the inner circulation, and is formed by additionally mounting a filter device on a lubricating oil system of the compressor unit; the lubricating oil system of the compressor unit comprises an oil tank, a main oil pump, a spare oil pump and a cooler connected through pipelines; a heater is arranged in the oil tank; the outer circulation system is formed by separating the inner circulation system from the unit by an over line; and a method of the inner circulation consists of the following steps: (1) an oil sealing ring at the outer side of an inner bearing of a compressor bearing tank is dismantled; and (2) the main oil pump is started to perform the inner circulation. The oil circulation method of the compressor unit can perform the inner circulation construction of the compressor unit without needing to charge sealing separation gas into a compressor sealing cavity, and has no need to depend on the clean sealing separation gas with stable pressure so as to preferably guarantee the oil circulation duration.
Description
technical field [0001] The invention relates to a lubricating oil circulation method, in particular to an oil circulation method of a compressor unit. Background technique [0002] With the continuous development of my country's petrochemical industry, the petrochemical plants of PetroChina, Sinopec, and CNOOC have been continuously built and expanded in recent years. In particular, my country's coal chemical industry is developing rapidly, and coal chemical plants such as coal-to-oil and coal gasification have been established in the west From now on, each set of equipment has N compressor units, and there are hundreds of compressor units in my country every year in oil circulation, commissioning, and start-up. The compressor unit needs to go through four important links from installation to feeding and output of products, namely: unit installation, unit oil circulation, unit commissioning and unit start-up. Among them, the oil circulation time of the compressor unit direct...
