Problems solved by technology

That is to say, the former is that the first oil 21a will be discharged to the system side in a large amount, and the latter is that the first horizontal rotary compressor will be short of oil, not only cannot be lubricated, but the first oil in the first motor chamber 8a will be caused by the rotation of the first rotor 6a. The agitation of 21a will reduce the efficiency of the first horizontal rotary compressor and increase the amount of oil discharged from the first exhaust pipe 14a.
[0013] Therefore, such technical issues have become the main reasons hindering the development of horizontal rotary compressors

[0051] see figure 2 , the second horizontal rotary compressor seals an appropriate amount of second oil 21b in the cylindrical second casing 1b, and the oil is usually lubricating oil. The outer diameter of the second main bearing 3b among the constituent parts in the second compression main part is fixed in the inner diameter of the second casing 1b, which is hereinafter referred to as the second pump body assembly 2b. The second motor assembly 4b is composed of a second stator 5b and a second rotor 6b, and the outer diameter of the second stator 5b is fixed in the inner diameter of the second housing 1b. The outer diameter of the second stator 5b is generally provided with a second planar portion 10b having four cutouts. The second flat portion is a passage for exhaust gas or oil in the second motor chamber 8b. The second rotor 6b is fixed in the outer diameter of the second eccentric crankshaft 12b.

[0070] Referring to FIG. 4 , it is a sectional view of a fourth horizontal rotary compressor whose internal pressure of the shell is high pressure. The fourth housing of the fourth horizontal rotary compressor 31 is composed of a cylindrical fourth middle housing 32 located in the center and a fourth right housing 33 and a fourth left housing 34 welded and sealed at its open end . A fourth pump body assembly 35 and a fourth motor assembly 36 are fixed inside the fourth housing 32 . Two assembly feet are installed on the lower side of the outside of the fourth housing 32 : a fourth assembly foot 37 and a fourth assembly foot 38 . An appropriate amount of fourth oil 39 is sealed inside the fourth housing. The fourth motor assembly 36 is composed of a fourth stator 41 and a fourth rotor 42 . The fourth stator 41 has a fourth planar portion 43 having four cutouts on the outer diameter portion. The fourth stator 41 is fixed at the inner diameter of the fourth housing, and the f...

Abstract

The invention relates to a lubricating system of a horizontal and rotary type compressor, a control method and application thereof. A sealed shell of the lubricating system of the horizontal and rotary type compressor is sealed with oil and is internally provided with a compression component which is at least composed of an eccentric crank shaft, a steam cylinder, a bearing, a piston and a sliding sheet and an electric motor component which is at least composed of a stator and a rotor; the outer diameter of the stator is provided with one or more plane(s) with a notch; the rotor is arranged on the eccentric crank shaft; the internal part of the shell is divided into an oil storage cavity and an electric motor cavity at least by a dividing part which is provided with an oil channel communicated with the oil storage cavity and the electric motor cavity; the eccentric crank shaft is axially provided with an air channel which leads from the oil storage cavity to the electric motor cavity; and the end part of one side of the rotor in the electric motor cavity is provided with a decompression device of the air channel. The invention has simple and reasonable structure, good effects of oil supplying and lubrication, stable oil level control in the compressor and higher reliability and working efficiency.

Description

technical field [0001] The invention relates to a horizontal rotary compressor, in particular to a lubricating system of the horizontal rotary compressor and its control method and application. Background technique [0002] The horizontal rotary compressor with the eccentric crankshaft placed in the horizontal direction has the great advantage that the overall height can be reduced compared to the vertical compressor with the eccentric crankshaft placed in the vertical direction. The machine system has the advantage of increasing the effective volume, such as increasing the effective volume of a showcase or a refrigerator. In bus or car air conditioners, horizontal rotary compressors can be directly mounted on the equipment with little adjustment. Because of this, the use of horizontal rotary compressors in most refrigeration equipment or some air conditioners is also increasing year by year. [0003] Since the motor in the horizontal rotary compressor is installed in the ...
