According to the refrigeration mode of the station, the hydraulic valve block can be divided into: 1. 2. Forced refrigeration: forced refrigeration is carried out by refrigerator, which is generally used in the system with oil tank capacity greater than 250 L.

The processing of hydraulic valve block, many people may only focus on technical issues, will ignore some auxiliary processing of hydraulic valve block, in fact, in the whole process of hydraulic valve block processing, auxiliary processing plays a very important part. Auxiliary processing includes valve body cleaning, parts deburring, heat treatment residue removal and cleaning.

Drilling and tapping shall be carried out according to the design requirements of the hydraulic valve block processing drawings: the slender hole shall be processed first, and then the short and coarse hole shall be processed.

The geometric dimension of the valve block mainly considers the external dimension of the components installed on the valve block, so that there is enough assembly space between the components. The distance between the hydraulic components should be greater than 5mm.

Then how to find the burr inside the hydraulic valve block, it must be detected by industrial endoscope. Through various processes and means, such as manual use of brush deburring, methane blasting method and so on, after deburring, it needs to be inspected by industrial endoscope to ensure that the deburring is completed.
