Problems solved by technology

[0002] We know that the cylinder is prone to internal leakage. If the working fluid in the pulling side and the pressing side of the cylinder are different, it will cause one working fluid to contaminate the other.

Embodiment Construction

[0005] A specific embodiment is introduced below, and the specific implementation manner is not limited to this one example.

[0006] The pull side of the cylinder is firstly filled with refrigerated oil or other lubricating oil that is incompatible with the refrigerant, and then connected to a variable-volume sealed container, and then filled with gas, and the push side of the cylinder is connected to the compressor and filled. Refrigerant injection, when working, even if there is leakage in the cylinder, the gas on the pulling side of the cylinder will not pollute the refrigerant on the pressing side of the cylinder due to the isolation effect of refrigerated oil or other lubricating oils that are not compatible with the refrigerant.

[0007] The structure of the variable-volume sealed container is similar to a U-shaped tube. The vertical part of the U-shaped tube with a small diameter is connected to the pulling side of the cylinder. The vertical part of the U-shaped tube wi...

Abstract

The invention provides a novel air cylinder sealing mode. According to the novel air cylinder sealing mode, a double-action type air cylinder and a sealing container with the variable volume are adopted, the air cylinder pulling side is filled with refrigerant oil or other lubricating oil not soluble with the refrigerant oil, the refrigerant oil or the other lubricating oil not soluble with the refrigerant oil has the lubricating effect and also has the isolation effect, and gas inside the pulling side of the sealing container with the variable volume is isolated from a refrigerant so that gas inside the pulling side of the sealing container with the variable volume can be prevented from permeating the detaining side of the air cylinder or polluting the refrigerant.

Description

technical field [0001] The invention provides a novel cylinder sealing method. This new type of cylinder sealing method uses a double-action cylinder and a sealed container with variable volume. The pulling side of the cylinder is filled with refrigerated oil or other lubricants that are incompatible with refrigerants. In addition to lubricating, it also plays an isolation role, separating the gas in the pull side of the variable-volume sealed container from the refrigerant, so as to prevent the gas in the pull side of the variable-volume sealed container from penetrating into the push side of the cylinder and polluting The refrigerant. Background technique [0002] We know that the cylinder is prone to internal leakage. If the working fluid in the pulling side and the pressing side of the cylinder are different, one kind of working fluid will contaminate the other. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
