The coking of the telescopic welded bellows cylinder block and valve is affected by the process. The cylinder block and valve body of the reciprocating pump are very easy to coke. The coking of the cylinder block and the piston will cause the piston to reciprocate in the cylinder block and increase the load; the valve body will coke. The exhaust is not smooth, the valve is not closed tightly, the load is increased, and the vacuum is low; coking at the clearance of the cylinder block will also cause the piston to collide with the cylinder and increase the load. The inspection found that the cylinder block and the valve plate are coking. This is the main reason for the low vacuum."
