Abstract
The invention discloses an oil sealing system with a head tank liquid level control function. The oil sealing system comprises an oil tank, a head tank, a compressor and an oil-gas separator. The oil tank is sequentially connected with a low-pressure pump, a cooler, a filter and a high-pressure pump in order through a pipeline and is further connected with a floating ring sealing chamber of the compressor. The floating ring sealing chamber of the compressor is combined with the oil tank through the pipeline to form a circulation system. The head tank is arranged at the upstream end of the whole system and is connected with a floating ring sealing chamber pipeline through a branch pipeline. The oil tank is connected with the compressor through the floating ring sealing chamber pipeline. Adjusting valves are used with a check valve to control the head tank. The floating ring sealing chamber is connected with the oil-gas separator through the pipeline. The oil sealing system has the advantages that with the oil in the head tank, oil-gas differential pressure is formed by a liquid level pressure head, and based on liquid level height, sealing oil is provided to the sealing chamber in case of emergency poweroff, so that sealing after stop is maintained.
Description
Technical field
The present invention relates to field of sealing technology, particularly relate to a kind of sealing oil system with high position tank Liquid level.
Background technique
Floating-ring seal is made up of the narrow and small annular space of floating between global axle, is full of liquid in annular space, and the ring of relative movement does not directly contact with axle, therefore is applicable to high speed and high pressure occasion.Sealing oil system is the lifeblood of floating-ring seal, has conclusive impact to the stability of floating ring, reliability.Existing sealing oil system, cannot make sealing oil system maintenance work after a stoppage, have impact on use.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of sealing oil system with high position tank Liquid level, can solve the problems of the technologies described above completely.
The technological scheme solved the problems of the technologies described above is as follows:
With the sealing oil system of high position tank Liquid level, comprise fuel tank, high position tank, compressor and deaerator, described fuel tank is connected in series low pressure pump successively by pipeline, cooler, filter, high-pressure service pump is also connected with the floating-ring seal chamber of compressor, the floating-ring seal chamber of described compressor and fuel tank form the circulatory system by pipeline, described high position tank is positioned at the upstream extremity of whole system, described high position tank is connected with the floating-ring seal lumen road being connected fuel tank and compressor by bypass line, and modulated valve and safety check coordinate control, the floating-ring seal chamber of described compressor is also connected by pipeline with deaerator.
Deaerator is arranged on the downstream of compressor, and is communicated with fuel tank by pipeline, this pipeline is also provided with pressure difference transmitter and regulator and modulating valve.
The outlet conduit being arranged in high-pressure service pump is also provided with a reflux line and leads to fuel tank, this pipeline is also provided with pressure transmitter and modulating valve and modulating valve and coordinates and control.
The present invention adopts two-step supercharging and adopts high-order tank liquor gas differential pressure regulation.Be stored in the oil sealing in fuel tank, send into cooler through low pressure pump and regulate oil temperature, then send into filter removal impurity, then use high-pressure service pump supercharging.Two-step supercharging mode of the present invention, makes cooler and filter work under lower pressure, reduces high-pressure bottle equipment, reduces cost.
A high pressure oil part enters high position tank, and all the other enter in floating-ring seal chamber, due to the level head of high position tank, makes oil pressure higher than air pressure.Small part oil sealing enters oil gas chamber through interior floating ring, in oil gas chamber, oil sealing is subject to medium pollution, become sump oil, as sump oil generation chemometamorphism, then introduce discharge, as sump oil only with some gas phase medias, chemometamorphism does not occur, then can introduce in deaerator, separated gas phase media leads back suction port of compressor, and isolated oil leads back in fuel tank and recycles.
The oil of high position tank, not only utilizes level head to form oil gas pressure reduction, and when emergency power off is stopped, can rely on liquid level, provide sealing oil to Seal cage, maintains the sealing after stopping.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure, 1 is fuel tank, and 2 is low pressure pump, and 3 is cooler, and 4 is filter, and 5 is high-pressure service pump, and 6 is modulating valve, and 7 is safety check, and 8 is pressure difference transmitter and regulator, and 9 is high position tank, and 10 is deaerator, and 11 is pressure transmitter and modulating valve, and 12 is compressor.
Embodiment
A kind of sealing oil system with high position tank Liquid level as shown in Figure 1, comprise fuel tank 1, high position tank 9, compressor 12 and deaerator 10, described fuel tank 1 is connected in series low pressure pump 2 successively by pipeline, cooler 3, filter 4, high-pressure service pump 5 is also connected with the floating-ring seal chamber of compressor 12, floating-ring seal chamber and the fuel tank 1 of described compressor 12 form the circulatory system by pipeline, described high position tank 9 is positioned at the upstream extremity of whole system, described high position tank 9 is connected with the floating-ring seal lumen road being connected fuel tank 1 and compressor 12 by bypass line, and modulated valve 6 and safety check 7 coordinate control, the floating-ring seal chamber of described compressor 12 is also connected by pipeline with deaerator 10.Deaerator 10 is arranged on the downstream of compressor 12, and is communicated with fuel tank 1 by pipeline, this pipeline is also provided with pressure difference transmitter and regulator 8 and modulating valve 6.The outlet conduit being arranged in high-pressure service pump 5 is also provided with a reflux line and leads to fuel tank 1, this pipeline is also provided with pressure transmitter and modulating valve 11 and modulating valve 6 and coordinates and control.
The present invention adopts two-step supercharging and adopts high-order tank liquor gas differential pressure regulation.Be stored in the oil sealing in fuel tank 1, send into cooler 3 through low pressure pump 2 and regulate oil temperature, then send into filter 4 and remove impurity, then use high-pressure service pump 5 supercharging.Two-step supercharging mode of the present invention, makes cooler and filter work under lower pressure, reduces high-pressure bottle equipment, reduces cost.
A high pressure oil part enters high position tank 9, and all the other enter in floating-ring seal chamber, due to the level head of high position tank, makes oil pressure higher than air pressure (about exceeding 0.05MPa).Small part oil sealing enters oil gas chamber through interior floating ring, in oil gas chamber, oil sealing is subject to medium pollution, become sump oil, as sump oil generation chemometamorphism, then introduce discharge, as sump oil only with some gas phase medias, chemometamorphism does not occur, then can introduce in deaerator 10, separated gas phase media leads back compressor 12 entrance, and isolated oil leads back in fuel tank 1 and recycles.
The oil of high position tank, not only utilizes level head to form oil gas pressure reduction, and when emergency power off is stopped, can rely on liquid level, provide sealing oil to Seal cage, maintains the sealing after stopping.
