Example Embodiment

[0017] Example 1, Figure 1 is a 3HP fully enclosed oil-free flexible scroll compressor. The compressor has a housing 6 mounted on the base 1. An intake pipe 11 is provided in the middle of one side of the housing, and an exhaust pipe 34 is provided in the upper part of the other side. The lower support 3 and the frame 22 are respectively fixed on the housing with positioning pins 2 and then welded and sealed. The main eccentric shaft 9 passes through the lower bearing 4, the shaft retaining ring 5, the upper bearing 18 and the main bearing 19, respectively, and the lower support 3, machine The frame 22 and the moving plate 23 are fixed, and the main eccentric shaft 9 is equipped with a counterweight 10. The movable disc 23 and the stationary disc 21 of the double function equation type line mesh with each other. The main features of this example are: 1) There are three eccentric pendulum shafts 15 on the back of the moving plate 23, the eccentric pendulum shaft is installed in the...

Example Embodiment

[0020] Example 2, Figure 2 is a 3HP fully enclosed oil-free digital scroll air conditioner compressor. The Digital Scroll Compressor is a variable-capacity scroll compressor, an energy-saving scroll compressor that can adjust the compression capacity according to changes in the cooling load. The oil-free design structure of the Digital Scroll is the same as in Example 1. The difference from Example 1 is that an electromagnet 41 is installed on the back of the static plate 21. The external control circuit controls the electromagnet to attract and disconnect, and change the static plate 21 and The spacing of the moving disc 23 forms two working states of unloading and load. Through the change of the time ratio of the switching of the two working conditions of unloading and load, the compressor can meet the operating requirements of different refrigeration loads and achieve the purpose of energy saving. After adopting oil-free, the fully enclosed oil-free digital scroll air-condition...

Example Embodiment

[0021] Example 3, image 3 It is an open-type oil-free digital scroll automobile air-conditioning compressor. The difference between this example and the previous two examples is that the car engine is directly driven by the pulley 51, and the maximum operating speed can reach tens of thousands of revolutions. The inner part of the pulley 51 is equipped with electromagnetic coil 52, pulley bearing 53, and shaft seal 54 in sequence. The main eccentric shaft 9 is equipped with a main shaft auxiliary bearing 55, and the end of the main eccentric shaft is equipped with a friction sheet 57, a spring sheet 56 and a spring. Sheet nut 58. The back of the static plate 21 is equipped with an attractor 60 and an electromagnet 61. Due to the oil-free design of the machine, the clogging of valves and pipelines no longer occurs. The use of digital control can ensure the stability of the cooling capacity.

Abstract

The invention relates to a non-oil cyclone air conditioning compressor, without using lubricant. The frame of compressor has a inlet tube and a outlet tube; the motor stator is fixed on the frame; the lower support and case of main axle are fixed and welded sealed on the frame via positioning pins; the main eccentric axle via lower bearing, upper bearing and main bearing is connected to the lower support, the frame and the movable disc; the static disc is fixed on the frame; the movable and static discs are meshed; and the main eccentric axle is mounted with a balance weight. It is characterized in that: three bearings of main eccentric axle all use self-lubricant bearings or sealed bearings; the back of movable disc has one group of eccentric swing axles with same eccentric distance as the main eccentric axle; said eccentric swing axles are fixed on the movable disc and frame via dual-sealed bearings. The invention has wider application.

Description

technical field [0001] The invention relates to an oil-free scroll air conditioner compressor. Suitable for residential, commercial and automotive air conditioning compressors. Background technique [0002] At present, there are many kinds of principle structures of air-conditioning compressors, but no oil-free air-conditioning compressors have been disclosed. The main purpose of using refrigerating machine oil in air-conditioning compressors is for mechanical lubrication, because the current commercial air-conditioning compressors cannot use lubricating oil in their mechanical structures, so in order to prevent the energy efficiency ratio from falling after using lubricating oil, Many research institutions minimize the adverse effects of using lubricating oil by optimizing the separation efficiency of lubricating oil and refrigerant and improving the miscibility of lubricating oil and refrigerant. [0003] In the traditional scroll air-conditioning compressor, the most co...
