Problems solved by technology
However, the high-speed reciprocating motion of the piston rod in the positioning bearing inevitably leads to contact and friction. This kind of dry friction has a large friction resistance, which consumes a lot of power and has low energy efficiency for the compressor; the dry friction between the two brings linear compressors The problem of poor reliability
The existing technology only lubricates the contact surface between the cylinder and the piston, but does not lubricate other positions

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0024] Such as figure 1 As shown, the linear compressor includes a linear motor, a mover component, a piston 8 and a cylinder 7, and the piston 8 is driven by the mover component to compress refrigerant in the space of the cylinder 7. The linear motor is composed of an outer stator 1, a coil 13, an annular permanent magnet ring 2 and an inner stator 3, wherein the inner and outer stators are respectively formed by stacking a plurality of silicon steel sheets. The cylinder 7 of the linear motor is installed on the front flange 11. The inner and outer stators of the linear motor are fixed. The inner stator 3 or the outer stator 1 is wound with a ring-shaped excitation coil 13, form...

The invention discloses an oil supply method and an oil supply device for a linear compressor and a linear compressor. The oil supply device comprises a pumping device and an oil-way arranged on a front flange, the pumping device and the oil-way arranged on the front flange are connected through an oil supply line, the oil supply device also comprises an oil conduit, one end of the oil conduit is connected with the oil-way arranged on the front flange and the other end of the oil conduit extends to the rear portion of a piston rod. Lubricant oil is pumped to the front flange of the linear compressor through the pumping device; the lubricant oil is delivered to the rear portion of the piston rod from the front flange through the oil conduit. By means of delivering the lubricant oil to the rear portion of the piston rod through the oil conduit, the oil supply device provides lubrication for the contact movement between the piston rod and bearings. Wear and tear of the movement positions between the piston and bearings can be effectively reduced, service life of spare parts can be prolonged, performance stability and service life of the linear compressor can be increased; friction coefficients and friction heat can be reduced, energy loss and friction power dissipation can be reduced, mechanical efficiency of the compressor can be increased and therefore energy consumption can be lowered. Temperature of the movement positions can be effectively decreased.
Description
technical field [0001] The invention relates to a linear compressor, in particular to an oil supply method and an oil supply device for a linear compressor. Background technique [0002] The linear compressor is used to suck the compressed fluid into the cylinder, and use the linear driving force of the linear motor to make the piston reciprocate linearly in the cylinder to compress the fluid, and then discharge the compressed fluid. When the compressor is working, the piston reciprocates at high frequency in the cylinder, and there is friction between the piston and cylinder, which will consume a certain amount of power. The friction may also cause impurities such as wear debris, which will aggravate the wear of the piston and cylinder, resulting in increased gas leakage. Large, the efficiency of compressed gas is reduced, and the aggravation of wear will not only cause damage to the piston and cylinder, but also may cause serious problems such as cylinder sticking. The in...
