Knowledge of the installation of the cylinder: 
 1. Equipment check before loading should be carefully checked before, do not pressure test should be specified (including the cylinder and water jacket); cleaning, checking the cylinder body and the body connect only the mouth area, chamber and the cylinder valve seat contact surface, etc. should be no mechanical damage and other defects, the cylinder mirror not have cracks, loose, porosity and other defects; with micrometer inspection at all levels of the working surface of the cylinder cylindrical, the deviation shall not be less than the national standard 8 tolerance value. 
 2. Horizontal compressor cylinder installation requirements 
 ① cylinder connected with the body, the response said, evenly tighten the bolts, the cylinder must support the use of pull wire line method ② find is the body slide in the cylinder axis with the axis of concentricity, should meet the following requirements. Body slide in the cylinder axis with the axis of concentricity error shall comply with the requirements in Table 3-24. If exceeds, the level should be done or cylinder radial displacement, or scraping to connect only to adjust the mouth, shall not be adopted or imposed by external forces plus side pad way to adjust. Treated only the mouth area, the contact area should reach 60%. Adjust the level of degree cylinder, the deviation of not greater than O. 05mm / m, and the tilt direction of the body should be consistent with the (high end of the cylinder head), but must meet the requirements in Table 3-24. Check the packing seat axis coaxial with the cylinder axis deviation, should also meet the above requirements. 
 3. Vertical installation of compressor cylinder 
 ① cylinder and body, the cylinder and the cylinder or cylinder connected with the body to deal with that tighten the bolts evenly, the bearing surface should be good contact, the force should be uniform. 
 ② cylinder level is measured, in only the cylinder head and cylinder on the plane on oral exposure; 150ram diameter greater than the working surface of the cylinder, the cylinder can also be measured on the mirror. The level of deviation, no larger than O. 05mm / m. 
 ③ In the Mouth contact with the cylinder can not be placed on Level Plane, it can block additional rules and flat feet, flat feet measured at the level of degree. 
 ④ cylinder with the body, the cylinder and the cylinder or cylinder with the axis of the body such as coaxial, shall meet the requirements in Table 3-24. The only contact with the mouth surface, the contact area should reach 60%. 
 ⑤ laser collimator alignment at all levels in the body of the cylinder axis and the axis of coaxial slide, the mirror should be placed in the cylinder to receive the optical axis of the cylinder coincides with the target center. Optical receiver and laser target beam axis center line deviation of not less than the national standard 9 tolerances. Good contact with the cylinder bearing surface, the force should be uniform.
