What are the reasons why a single cylinder of a high-pressure coal slurry pump does not deliver any flow? All kinds of guesses are welcome.
Large solid particles or debris in the coal slurry cause the check valve to stick
1. Solid particles causing caking in the coal slurry 2. Oil and gas not fully drained from the single cylinder 3. Damage to the check valve, inlet passage
We welcome everyone to actively participate in the discussion.
One more thing: there are problems with the oil injection system, including pressure gauge leaks and solenoid valve failures
I think that solenoid valve is the most likely to develop problems
If it suddenly stops working while in operation, it is usually due to insufficient hydraulic oil, a stuck check valve, or severe wear.
Large-particle cushion cylinders, damaged valve seat sealing rubber, insufficient drive fluid, excessive sediment accumulation at the blind flange of the inlet pipe, severe wear on the valve ball and seat
