Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of poor reliability of the pressure wave generation system of the oil-free stable flow compressor refrigerator in the prior art, high manufacturing cost and short life of the plane rotary valve, and easy saturation of the oil filtration system. Therefore, it is possible to provide a pressure wave generation system for oil-lubricated, stable-flow compressor refrigerators that can use oil-lubricated planar rotary valves, eliminate the saturation problem of complex oil filtration systems, and have high reliability and low cost.

Embodiment 1

[0022] Such as figure 2 As shown, the pressure wave generation system for a GM refrigerator provided by the present invention includes: a valve-type piston compressor driven by a rotating motor connected in sequence and forming a loop 1, a first oil and gas pipeline 2 and the The first one-way valve 3, the planar rotary valve 8 installed between the rotating electric machine 9 and the refrigerator, the second oil and gas pipeline 5, and the fourth one-way valve 14. Between the plane rotary valve 8 and the refrigerator is installed an elastic membrane 15 made of a Viton brand fluororubber material produced by DuPont in the United States.

[0023] The lubricating oil installed at the bottom of the compressor 1 is compressed by the compressor and enters the plane rotary valve 8 with the gas to make it well lubricated. The lubricating oil accumulated in the valve returns to the compressor with the gas when the refrigeration system is low in pressure. , And repeat the cycle.

Embodiment 2

[0027] Such as image 3 As shown, the pressure wave generation system for a GM refrigerator provided by the present invention includes: a screw compressor 1, a first oil and gas pipeline 2, which is installed between the rotating electric machine 9 and the refrigerator, which are sequentially connected and form a loop Plane rotary valve 8, second oil and gas pipeline 5. An elastic membrane 15 made of beryllium bronze is installed between the plane rotary valve 8 and the refrigerator.

[0028] The lubricating oil installed at the bottom of the compressor 1 is compressed by the compressor and enters the plane rotary valve 8 with the gas to make it well lubricated. The lubricating oil accumulated in the valve returns to the compressor with the gas when the refrigeration system is low in pressure. , And repeat the cycle.

[0029] The planar rotary valve 8 is driven by the rotating electric machine to alternately communicate the connecting pipe of the refrigerator with the high and low ...

Abstract

The invention relates to the pressure wave producing system of the oil-lubricating stable flowing compressor refrigerator. It comprises the compressor orderly connected and forming the loop, the oil conveying pipeline, the plane revolving valve between the revolving electric machine and the refrigerator. Its characteristics are: it also includes the elastic film equipped between the plane revolving valve and the refrigerator; the said plane revolving valve is lubricated by oil. The said elastic film is the organic or metal material film with high elasticity. Compared with the prior art, the key technology of the invention is that it adopts the high-elasticity film that can effectively convey the mechanic power to the refrigerating system in sound wave pattern and prevent the lubricating oil in the pressure wave producing system going into the refrigerating system. It makes the GM refrigerator maintain the high efficiency and improve the reliability and greatly reduces the cost.

Description

Technical field [0001] The invention belongs to the technical field of refrigeration and low temperature, and specifically relates to a pressure wave generating system for an oil-lubricated stable flow compressor refrigerator for a GM refrigerator or a GM pulse tube refrigerator. Background technique [0002] Low-temperature refrigerators driven by stable-flow compressors, such as GM refrigerators and GM pulse tube refrigerators, are small regenerative low-temperature refrigerators using cold storage. The low temperature part has a compact structure and high cooling efficiency. At present, the pressure wave generating system of this type of refrigerator all contains a complicated oil lubrication filter system. Take a low-temperature refrigerator driven by a valved piston compressor as an example, such as figure 1 As shown, the pressure wave generating system of a typical GM refrigerator includes a compressor 1, a first oil and gas pipeline 2 and a first one-way valve 3, and a se...
