Rotary valves are widely used. So, what debugging skills does it have? I believe that many of my friends don’t understand this very well. Let me briefly introduce it to you, let’s take a look!

Rotary valve

Debugging method of rotary valve

1. Check the fastening of each part and whether the positioning pin is loose.

2. There is no oil leakage inside the rotary valve body.

3. There should be no scaling, rusting and peeling inside the rotary valve body.

4. Pay attention to whether the lubrication and heat dissipation are normal, pay attention to the quality of the lubricating oil, often listen to whether the rotary valve is noisy, pay attention to whether the unit is operating under conditions that do not meet the requirements, and pay attention to regularly adding butter.

5. The overload of the rotary valve is sometimes not displayed immediately, so pay attention to the increasing development trend of inlet and exhaust pressure, bearing temperature and motor current to judge whether the machine is operating normally.

6. Before disassembling the machine, measure the matching dimensions of various machines, make a record, and mark the rotation on the parts, and what debugging skills are there to ensure that the original matching requirements are maintained after the product is assembled.

Reasons for hydraulic clamping of rotary valve

Dirt enters the gap; the temperature rises, and the valve core expands, but the main reason is that the change of the side shape and coaxiality of the rotary valve causes the influence of the radial unbalanced force. When the valve core is affected by the radial unbalanced force effect and the valve hole When the liquid in the gap is squeezed out, the conflict between the valve core and the valve hole becomes a semi-dry conflict or even a dry conflict, and the force required to move the valve core from the head is much greater.
