Technical requirements for the matching parts of the machine, pump and mechanical seal: a. c. All parts in the assembly meet the requirements of the drawings.6.1mm.05mm.1. e. The amount of vibration of the shaft where the mechanical seal is installed shall not be greater than 0. The compression of the spring shall be allowed to be within ±2mm according to the drawing.5mm. The shaft manufacturing tolerance of the mechanical seal is h8, and the finish is 1. b. 2. c. When tightening the gland, it should be done after the coupling is aligned.

The end of the shaft (sleeve) where the moving ring sealing ring is installed and the end of the sealing gland (or housing) of the quiet ring sealing ring should be chamfered and polished. d. The compression screws should be tightened to prevent the flange surface from deflection. b. The maximum shaft curvature should not exceed 0. The axial movement of the shaft is not allowed to be greater than 0. c.. Installation requirements for pump mechanical seals: d. After the moving ring is installed, it must be Bearing C28 ensured that the moving ring can move flexibly on the shaft

The group fixture is designed according to the group technology principle. In use occasions, the use of universal fixtures to clamp the workpiece is time-consuming, complicated in operation, low in production efficiency, and difficult to clamp. Used for trial of new products and small batch production of multiple varieties. 3. As long as some components of the fixture are slightly changed, different components in the group can be processed. 2. ⑤　The accompanying fixture is a fixture used on automatic lines.1. Flat vise, indexing head, rotary table on milling machine. 4. ④　Combined fixture is a fixture that is easy to connect and disassemble from standard fixture parts that can be recycled.
