Regarding the oil circuit of the engine set
Thread Content
I would like to ask everyone if there is any information available regarding the design of the oil circuit or oil stations in compressors; I’m interested in learning about the design principles and requirements, etc. Thank you!
It actually falls under the category of pressure vessels; take a closer look at the national standards
There should be relevant information available on the forum. The oil circuit mainly includes the following elements: a safety valve is installed at the outlet of the oil pump; a bypass and a temperature control valve are used in the oil cooling system; a pressure regulating valve is installed after oil cooling (send it to the email address); a self-acting pressure regulating valve or a pneumatic pressure control valve is used for the oil supply lines; and orifice plates or pressure regulating devices are used at the oil supply points.
You can refer to API614.
The oil circuit of the engine unit includes: oil tank, oil pump, oil filter, oil cooler, oil heater, control valve, oil pipelines, and control system
The unit’s oil station is part of the unit, while the pipelines constitute another part of it. Regarding the oil station, the main aspects include the following: First, the design approach: it is necessary to maintain good communication with design firms and various equipment manufacturers to determine the amount of oil required for each individual unit. After that, considerations are given to the volume of the overhead oil tanks, as well as the volume of oil in accumulators, pipelines, oil coolers, and oil filters. By adding a safety margin, the capacity of the oil tanks can be determined. The size of the orifices is determined based on the oil consumption at each supply point. The oil pressure is set according to the requirements of dry gas seals and other sealing components, as well as the needs of the equipment itself, in accordance with API standards, national standards, or industry-specific standards. Finally, the flow rate of the oil pumps is determined by taking into account the total volume of oil required at all supply points along with the appropriate margin. Second, manufacturing and material selection: the grade of pressure vessels is determined based on the oil pressure, their volume is calculated based on the amount of oil required, and the cooling area is determined based on the heat generated due to friction. Additionally, the precision of oil filtration is considered based on the requirements of the equipment or the customer. Lastly, the materials for various subsystems of the oil station are chosen in accordance with standards or customer requirements, whether it’s all stainless steel or a combination of different materials； There are too many things to consider, too many to list; what’s mentioned above are merely immature personal thoughts for reference only.
Thank you all, it’s very useful; I’ve found the right direction!
It is necessary to know parameters such as oil consumption and pressure. Only then can the size of the fuel station, the diameter of the pipes, the heat exchange area of the oil cooler, the power of the heater, the head and flow rate of the pumps, as well as the precision and flow area of the filters be determined.
The oil pipe must be pickled before being put into operation
