Description
The present invention relates to the compressor engineering, more particularly, is the vertical compressor lubricating system.
The present invention is used for the prestart friction pair does not have the lubricated more favourable of the sealed mode refrigeration compressor of pressure lubrication and other piston type compressed machine bearings.
Existing vertical compressor lubricating system (SU.A.840464), it comprises axial, the vertical and radial direction oil that is located in the axle, with oil sump and friction surface UNICOM.The safety check that is installed in axial oil duct bottom stops lubricant oil to be flowed out by axial oil duct when the compressor stall, thereby has guaranteed that lubricant oil can promptly enter bearing after compressor start.
But, native system can not guarantee lubricant oil energy engaging friction pair before compressor start, like this, just not lubricated at the starting initial stage, and axially oil duct is interior because its little trapped fuel of volume is limited, can not be used as oil conservator to it and use, in addition, when compressor stops, lubricant oil will flow away from radial direction oil hole.
Described lubrication system can not guarantee that the reliability of compressor and durability have high index because the starting initial stage has to lubricate.Therefore, working life of compressor has been placed restrictions in the heavy wear of friction surface during starting.
Task of the present invention is a kind of lubrication system for compressor of development, and it can guarantee that on structural design lubricant oil advances into friction surface in compressor start.
The solution of the task of carrying is that the vertical compressor lubricating system comprises axial, the vertical and radial direction oil that is located in the axle, with oil sump and friction surface UNICOM.According to the present invention, top at the axle internal oil channel is provided with cavity, be provided with valve in cavity and the place that axial oil duct communicates, this valve is made rod-type and axle coaxial line, axially can to-and-fro motion, simultaneously, be provided with auxiliary horizontal oil duct in axle, its upper end enters cavity, and the lower end communicates by means of safety check and oil sump.
Valve preferably has electromagnetic gear.
The transmission of valve can be by means of the time relay at compressor start front opening valve, and by means of action of gravity lubricant oil is sent into bearing from oil storage cup.
By the lubrication system for compressor of the present invention's development, relatively simple for structure, provide to friction pair because compressor start is instantaneous, thereby improved its reliability and durability.
With accompanying drawing an object lesson of the present invention is narrated below, wherein
Fig. 1 for according to the present invention by lubrication system for compressor radial direction oil axis make the axle the axial section sketch;
Fig. 2 is the axle diagrammatic sectional view according to II-II on Fig. 1;
Fig. 3 for according to the present invention by the horizontal auxiliary oil channel center line of lubrication system for compressor make the axle the axial section sketch;
Fig. 4 be by I Y-I Y on Fig. 3 make the axle the cross section sketch.
According to the present invention, this system is used for the lubricated of compressor, and this compressor has vertical shaft 1(Fig. 1), axle has bearing journal 2 that is bearing in the main bearing 3 and the crank 4 that is bearing in the connecting rod bearing 5.Be provided with cavity 6 on the top of axle 1, seal with end cap 7, with valve 9 and axial oil duct 8 UNICOMs, valve 9 is made rod, with axle 1 coaxial line, and can to-and-fro motion.Valve 9 is by means of electromagnetism transmission mechanism 10 motions, and driving mechanism 10 is made the form of magnetic plug, is contained on the compressor housing 11.Axially oil duct 8 is by means of the friction surface UNICOM of radial direction oil 12 and horizontal oil duct 13 and bearing 3 and 5.Oil stifled 14 is arranged in the bottom of axle.Laterally oil duct 13 enters oil sump by means of safety check 15 and the oil sump (not shown) that communicates through the lower end of axle 1.
The lower end of axle 1 is provided with auxiliary horizontal oil duct 16(Fig. 3), its upper end enters cavity 6, and the lower end communicates by means of safety check 17 and oil sump.
The work of lubrication system for compressor is as follows:
Lubricant oil enters oil duct 13 and 16 respectively by safety check 15 and 17 under the action of centrifugal force of oil sump generation when compressor shaft 1 rotates in the working procedure of compressor, and the lower end of axle 1 is immersed in the oil sump.Lubricant oil enters in the bearing 3 and 5 of radial direction oil 12 and compressor from oil duct 13.Cavity 6 is filled with lubricant oil by oil duct 16.Lid 7 stops lubricant oil to flow in the compressor housing 11 from cavity 6.During the compressor stall, the valve 9 of cutting out cuts off cavity 6 and axial oil duct 8, stops lubricant oil to flow out from cavity 6.Connect electromagnetism transmission mechanism 10 before the compressor start, the bar of its aspirating valve 9 is connected cavity 6 and axial oil duct 8.Lubricant oil enters axial passage 8 from cavity 6 under action of gravity, radially passage 12 enters bearing 3,5, is full of lubrication gap wherein.After this, connect compressor by means of the time relay, and electromagnetism transmission mechanism 10 cuts off, valve 9 cuts off cavity 6 and axial oil duct 8, guarantees that cavity 6 is full of machine oil.Like this, compressor next time prestart can realize lubricant oil engaging friction surface.
This compressor lubrication system has reduced start-up wear, thereby has improved reliability and the durability of compressor because when starting ensured the lubricated of friction surface. Sealed refrigerating compressor adopts this lubricating system to reduce wear and makes an appointment with half, thereby has prolonged its operating period and life-span.
