1、 Advantages of using negative gas cylinder liner for wet gas cylinder liner:
It is used to simplify the medium pressure cylinder
2. Wear resistance can be increased with better data
3. Increase or decrease the wall thickness, change the diameter of chamber within a certain range, and realize cylinder serialization
Information about wear resistance of the cylinder is available when there is gas erosion or not.
Problems: increase the number of two pieces and machining and installation; increase the possibility of water jacket leakage.
The wall thickness of wet cylinder liner is the same as that of cylinder inner wall.
2、 Dry cylinder liner
The cylinder on the inner wall of it is a cylinder. The advantages and disadvantages of dry cylinder liner are adopted.
1. Advantages: A. better wear-resistant data can be used for cylinder liner to reduce the amount of maintenance work
B. after the cylinder liner is worn, it can be removed and replaced without machining the cylinder
C. the thickness of cylinder liner can be changed and the diameter of chamber can be changed properly
D. when there is no oil lubrication for corrosive gas or cylinder, the response corrosion resistance data can be used.
It also increases the cost of processing equipment.
B. when replacing the cylinder liner, the cylinder head must be disassembled with professional tools, so as to deal with those forged cylinders with tight and clean gas and excellent lubrication, do not process the cylinder liner first. After the cylinder is worn, remove the cylinder and re bore, then press in the cylinder liner. However, due to the poor wear resistance of the steel cylinder, dry cylinder liner must be set when there is oil lubrication.
In case of dry cylinder liner breakage.
D. the existence of cylinder liner also worsens the heat conduction of cylinder wall.
