The oil supply device can continually supply oil to the interior of the compressor in the event of emergency stop of the compressor due to power cut or failure, improves the system reliability, reduces the requirements for part maintenance and assembly, and is reasonable in design and convenient and practical to use.
Description
Technical field
The utility model is a kind of centrifugal compressor high tank emergency oil supplying device, belongs to the renovation technique of centrifugal compressor high tank emergency oil supplying device.
Background technique
In the centrifugal compressor of large-scale chiller plant, bearing lubrication mainly forces fuel feeding to carry out by oil pump.But when oil pump breaks down, in compressor protection emergency shutdown process, also must take certain measure to continue fuel feeding and be lubricated to bearing until the compressor dead halt.Existing centrifugal compressor is designed with high tank or energy storage oil cylinder more.But high tank does not design emergency oil supplying device mostly at present: in the oil pump fault stopping process, rotor shaft also runs up continuing, and the high tank top is along with the minimizing of oil easily forms the lower low pressure area of relative gear housing pressure, under differential pressure action, oil in high tank can not rely on deadweight to flow to swimmingly the bearing that relatively runs up and be lubricated, cause bearing mechanical wear; And the energy storage cylinder structure is complicated, and cost is high, and reliability is low.
Summary of the invention
The purpose of this utility model be to consider the problems referred to above and provide a kind of when compressor because having a power failure or continuing to provide lubricant oil for compressor inside when hindering emergency shutdown for some reason; improve system reliability, reduce the centrifugal compressor high tank emergency oil supplying device of compressor components maintenance and matching requirements.The utility model is reasonable in design, and is convenient and practical.
The technical solution of the utility model is: centrifugal compressor high tank emergency oil supplying device of the present utility model, include high tank, one-way joint body and control valve, one end of one-way joint body is provided with bounding means, the other end is provided with confined planes, and confined planes is provided with the through hole that communicates with high tank, bounding means can contact or break away from, make the through hole that is provided with on confined planes communicate with high tank or seal under the effect of pressure reduction with the set confined planes of one-way joint body, control valve is installed between the bounding means and confined planes of one-way joint body.
Above-mentioned bounding means is resilient key.
Above-mentioned confined planes is conical surface.
Above-mentioned one-way joint body is installed in the position of high oil level of high tank.
Above-mentioned control valve is spherical steel ball.
The utility model is owing to adopting as long as control valve is limited in the structure of the position of opening and closing of one-way joint body by bounding means and confined planes, the utility model compared with prior art, the advantage that has is can well guarantee the mounting point of each part by machining, simple and compact for structure, assembling, easy to maintenance connects reliable.Utilize the utility model can guarantee that thereby gear housing and high tank top pressure balance in case of necessity make oil in high tank be unlikely to produce bearing to the bearing normal fuel injection by Gravitative Loads and produce abnormal mechanical wear because of emergency shutdown process lack of lubrication, thereby extended the working life of each moving element.The utility model is that a kind of design is ingenious, function admirable, convenient and practical centrifugal compressor high tank emergency oil supplying device.The utility model because having a power failure or continuing to provide lubricant oil for compressor inside when hindering emergency shutdown for some reason, improves system reliability when compressor, reduces compressor components maintenance and matching requirements, and is reasonable in design, convenient and practical.

Embodiment
Embodiment:
structural representation of the present utility model such as Fig. 1, 2, shown in 3, centrifugal compressor high tank emergency oil supplying device of the present utility model, include high tank 4, one-way joint body 1 and control valve 2, one end of one-way joint body 1 is provided with bounding means 3, the other end is provided with confined planes 6, and confined planes 6 is provided with the through hole that communicates with high tank 4, bounding means 3 can contact or break away from the set confined planes 6 of one-way joint body 1 under the effect of pressure reduction, make the through hole that confined planes 6 is provided with communicate or seal with high tank 4, control valve 2 is installed between the bounding means 3 and confined planes 6 of one-way joint body 1.
In the present embodiment, above-mentioned bounding means 3 is resilient key.Above-mentioned confined planes 6 is conical surface.
In the present embodiment, above-mentioned one-way joint body 1 is installed in the position of the highest oil level 5 of high tank 4.Above-mentioned control valve 2 is spherical steel ball.
Working principle of the present utility model is as follows: as shown in Figure 3, when normal operation, in the oil-filled oil storage process of high tank, spherical steel ball breaks away from the set conical surface of one-way joint body 1 by deadweight, enters gear-box by the set through hole of one-way joint body 1 after the oil extruding that the gas of high tank top chamber is injected into.When high tank was filled with oil, pressure oil was pushed spherical steel ball to one-way joint body 1 set conical surface, in case gang up inside and outside high tank.When emergency appears in oil pump; during compressor shutdown protection process; in high tank trapped fuel by the fuel feeding of conducting oneself with dignity in advance to corresponding bearing lubrication; along with time history; the lower pressure space appears in the high tank top; spherical steel ball breaks away from the set conical surface of one-way joint body 1 under high tank top and the effect of gear housing pressure difference; impel high tank top and gear housing pressure to reach balance, guarantee that in high tank, oil can be unlikely to produce bearing because of emergency shutdown process lack of lubrication generation inordinate wear to the bearing normal fuel injection by deadweight.The utility model can well guarantee the mounting point of each part by machining, assembles easy to maintenance, reliable.Can guarantee that the interior oil of high tank continues to be unlikely to produce bearing to the bearing normal fuel injection and produce abnormal mechanical wear because of lack of lubrication in the emergency shutdown process when emergency shutdown, extend the working life of each moving element.
