What problems should be paid attention to when assembling the valve block of waste paper baler
A precision component in the hydraulic system of the hydraulic waste paper baler is a hydraulic valve block. The valve block is a small circuit that gathers various valves that are used through the oil holes on the valve block, such as a balance we use now. The valve block contains balance valves, pressure reducing valves, safety valves, one-way valves, reversing valves, and shuttle valves.
The assembly of the hydraulic valve block needs to be carried out in accordance with certain principles to ensure that the valve block assembly is qualified.
The precautions for the assembly operation of the valve block of the waste paper baler are as follows:
1. All the oil holes of the valve block should be pickled before installation to ensure that there is residue in the oil holes. After cleaning, they should be evenly fastened to the foundation with bolts. The installation direction and position should not be wrong and should meet the requirements of the drawings.
2. The sealing surface of the valve block must not be scratched or damaged (especially when soft materials are used to pack or isolate them from each other during transportation to avoid collisions), and the verticality of the threaded holes should meet the requirements of the drawings, as shown in the picture. Requirements should be implemented in accordance with relevant standards or without tolerances.
3. Before installation, all types of valves should be checked with the design drawings for their models and specifications. There are often multiple types of valves combined into one valve block. When installing, it should be distinguished whether the direction, position, overlap level, etc. meet the requirements of the drawing.
4. The installation and sealing surfaces of the valve and valve block should be intact, the seals should be intact and free of defects, and the bolts should be fastened evenly, reliably and without leakage.
5. All connecting threads must be coated with anti-loosening glue for thread fastening.
6. Before assembling each valve and valve block, each oil port should be blocked to avoid the entry of dust.
7. All joint bodies, flanges and other connecting parts should be thoroughly cleaned before assembly to ensure that there is no residue in the oil hole before assembly.
