Description
[technical field]
The present invention relates to compressor apparatus, particularly relate to a kind of compressor oil supply structure and adopt the horizontal rotary compressor of this oil supply structure.
[background technique]
Horizontai rotary compressor is low due to center of gravity, shakes the advantage such as little and is widely used in the application system such as refrigerator, air-conditioning.The oil supply system of Horizontai rotary compressor is the key ensureing that compressor runs well, and has important impact to the performance of compressor, noise and life-span.The oil circuit of horizontal compressor generally will make lubricant oil enter bent axle, then by bent axle radial hole to working surface fuel feeding and provide sealing.
The Horizontai rotary compressor of present technology, as depicted in figs. 1 and 2, bent axle a is clear opening structure to the general oil supplying device structure adopted, and the rotor of bent axle a afterbody end is installed fuel feeding fan b; Wherein, the equilibrium block d on rotor c just merely plays the effect of kinetic balance.As depicted in figs. 1 and 2, during this compressor operating, fuel feeding fan b is along with the rotation of rotor c, under the influence of centrifugal force, the bent axle a afterbody of fuel feeding fan b immediate vicinity forms low pressure, there is pressure difference with oil sump space, fuel sucking pipe e place, under the effect of pressure difference, oil enters fuel sucking pipe e and rises to bent axle a head, then from bent axle header stream to bent axle afterbody, gets back in oil sump; Meanwhile, the oil in bent axle a under the effect of crankshaft rotating centrifugal force, by each radial hole to working surface fuel feeding and provide sealing.If do not fill fuel feeding fan, as shown in Figure 3 and Figure 4, the pressure at the pressure ratio fuel sucking pipe place of motor leftward space is high, oil can not enter fuel sucking pipe, and can find out in bent axle do not have each bearing working face of oil supply, Horizontai rotary compressor can not continue to carry out work, thus affect the performance of compressor, even can not good cooling motor, cause motor overheating, under some condition, also can cause the breaking-up of compressor because of motor overheating.
In addition, containing more lubricant oil in the pressurized gas of discharging compressor, too much lubricant oil can affect pressurized gas heat exchanging function in systems in which, the efficiency of system is reduced, thus have and have oil guard in horizontal compressor, under normal circumstances, it is the grease baffle that sheet is set on rotor, the amount of a certain amount of discharge pressurized gas can be reduced, but due to the setting of grease baffle, in the flowing of motor cavity, obstruction is caused to pressurized gas, reduce the mobility of gas at motor cavity, have impact on the effective temperature-reducing to motor, add the harm that motor overheating causes.
[summary of the invention]
The invention provides a kind of structure equilibrium block simple, easy to assembly and oil supply structure, effective minimizing enters the lubricants capacity of application system, strengthen pressurized gas heat exchanging function in systems in which, improve the efficiency of compressor, also save the processing of bearing thickness material and bearing relief opening simultaneously, reduce the compressor oil supply structure of compressor cost and adopt the horizontal rotary compressor of this oil supply structure.
