Problems solved by technology

However, in actual use, when the linear compressor starts or operates at a lower ambient temperature, the low-temperature liquid refrigerant will enter the cylinder 6 from the suction tube 9, causing abnormal impact, that is, liquid hammer phenomenon.
Liquid hammer is easy to damage the exhaust valve plate of the cylinder, causing deformation and rupture of the valve plate, resulting in low safety and reliability of the linear compressor in the prior art

Abstract

The invention provides a linear compressor and a refrigerant preheating method. The linear compressor comprises a shell and further comprises a stator, a rotor, an air cylinder, a piston, a spring pressing plate, an air suction barrel and an oil pump which are arranged in the shell, lubricating oil is stored in the bottom of the shell, a main oil supply pipe and a preheating oil supply pipe are connected to the oil pump, the main oil supply pipe is used for feeding the lubricating oil to the air cylinder, and the preheating oil supply pipe is used for feeding the lubricating oil to the air suction barrel. Safety and reliability of the linear compressor are improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a linear compressor and a refrigerant preheating method. Background technique [0002] At present, there are two types of compressors used in refrigeration equipment: rotary and linear, such as figure 1 As shown, the linear compressor in the prior art usually includes a casing 1, a stator 2, a coil 3, a mover 4, a piston 5, a cylinder 6, a spring back baffle 7, a spring 71, an oil pump 8 and an air suction cylinder 9, etc. Component composition; wherein, the mover 4 is provided with a magnet 41, the magnet 41 is inserted in the magnetic field space formed by the stator 2, a coil 3 is placed in the stator 2, one end of the piston 5 is connected to the mover 4, and the other end of the piston 5 Inserted in the inner cavity of the cylinder 6, the suction tube 9 is arranged on the spring back baffle 7, and the piston 5 will suck gaseous refrigerant through the suction tube 9 during the reciprocating ...
