Abstract
The utility model relates to a steam turbine oil supplying device, which is composed of an oil tank, an oil inlet arranged on the oil tank, a baffle in the oil tank, a filter connected with an upper end of the baffle, an oil supplying chamber and an oil returning chamber formed by the baffle, an oil level meter and an oil pump. Oil holes are evenly distributed on the baffle, filtering nets are mounted on the oil holes. The utility model has large filtering net flow area, and can reduce the oil circulating multiplying factor, enable the oil and water to be separated sufficiently, reduce the oil grease emulsifying speed, eliminate the dead corner of the oil returning chamber, improve the safety and the stability of the apparatus operation and can be convenient for the operation personnel to monitor.
Description
Technical field
The utility model relates to oil supplying device, specifically belongs to the oil supplying device of steam turbine.
Background technique
The function of steam turbine is that the heat energy with steam is converted into mechanical energy and exports former moving merit and drives other equipment operations, realizes Conversion of energy.Steam turbine is in running, and oil system is being undertaken the lubricated of steam turbine and regulated important task, and safe operation plays key effect to steam turbine for intact, the stable operation of assurance oil system.
At present, because the filter screen grid and the magnetic filter circulation area of installing in the steam turbine oil tank are too small, cause oil revolute chamber's oil mass constantly to increase, and fuel feeding chamber oil mass underfeed, finally cause oil revolute chamber and fuel feeding chamber oil level difference excessive, oil revolute chamber's oil part is from the overflow of fuel tank overflow pipe (the high-voltage electric oil pump is stopped transport moment, and when unit body oil refluxed, spillway discharge was bigger); Another part directly enters the fuel feeding chamber from the top overflow of filter screen grid, and after the oil of filtered entered steam turbine, the quality of oil can not get guaranteeing that safe operation causes very big threat to steam turbine.Oil spill stream not only causes the oil waste, and crosses when hanging down when fuel feeding chamber oil level, returns unit operation and brings following problem:
1) oil level indicator demonstration in the fuel tank left and right sides is inconsistent, has big difference, and the personnel control brings difficulty to the post;
2) fuel feeding chamber oil level is crossed when hanging down, and causes the steam turbine control system poor stability, and fluctuation of load is big;
3) fuel feeding chamber oil level is low excessively, at oil gun inlet possibility entrained air, cause the oil pipe line vibration big, and behind entrained air in the oil, lubrication pressure descends, and returning-oil temperature raises, and influences the steam turbine bearing cooling effect;
4) when being with air in the oil, bearing shell can't form oil film, causes unit vibration to strengthen;
5) have only fuel tank top because oil revolute chamber's oil flows into path, fuel feeding chamber, thereby cause oil revolute chamber's middle and lower part oil mobility poor, form the dead angle, reduce the fuel tank actual volume, cause oily circulating ratio to increase.
The model utility content
The purpose of this utility model is to solve the deficiency of present existence, provides a kind of filter screen circulation area big, satisfies the required oil mass of unit operation, and guarantees the oil supplying device of oil revolute chamber and the normal steam turbine of fuel feeding chamber oil level.
Realize the technical measures of above-mentioned purpose:
The steam turbine oil supplying device, fuel feeding chamber that forms by the filler opening on fuel tank, the fuel tank, the dividing plate in the fuel tank, the filter that is connected with dividing plate upper end, by dividing plate and oil revolute chamber, oil level indicator are formed, it is characterized in that: on dividing plate, be evenly equipped with oilhole, filter screen is housed on the oilhole.
Characteristics of the present utility model are that the filter screen circulation area is big, and the oil level difference of fuel feeding chamber and oil revolute chamber is reduced in the 10mm, and the oil of oil revolute chamber middle and lower part enters the fuel feeding chamber by the new clothes filter screen, have eliminated the oil revolute chamber dead angle, have satisfied the timely fuel feeding of turbine oil system.Simultaneously, improve equipment operation Security and stability, improved unit efficiency; Make things convenient for the operations staff to monitor; Economize on oil mass, avoid waste, reduce cost; Strengthen oil mobility, increased the fuel tank actual volume, reduced the circulating ratio of oil, oil is fully separated with water, reduced grease emulsifying speed.
