How does the viscosity of lubricating oil affect the valve plates in gas valves?

Our factory uses 46# anti-wear hydraulic oil for lubricating the spindle, connecting rods, and crossheads; I guess that’s not what you’re asking about. (Don’t use bricks for this purpose.) 150# is used inside the cylinder in winter, and 220# in summer. May I ask if your compressors have crossheads? If not, then I’m afraid there’s nothing I can do. If so, please keep reading. Both 150# and 220# are oils with high viscosity; they are primarily used here for lubrication between pistons and cylinders. Inject it into the cylinder using a plunger pump-type oil injector. A pressure of 16 Mpa. The normal oil injection rate under normal conditions is 20–30 drops per minute. If the amount is too large, excess oil will be pushed by the piston rings into the valve chamber. If it enters the air valve, its viscosity will cause delays in the opening and closing of the valve, as well as uneven stress on the spring and valve components, thereby accelerating their wear and damage. Carbonization occurs in cylinders with higher exhaust temperatures. It will also cause harm to the air valve. I’m not sure about the specific formula either. I’m sorry.

Our compressors here are 4-row opposed H-type compressors, double-acting. When it was first put into use, the valve plates kept getting damaged. It was eventually determined that the high viscosity of the cylinder lubricant (the standard specified in the manual is a lubricant with a viscosity of 200–300#) caused the valves to open slowly, which in turn led to excessive force being exerted on the valve plates. By switching to Holbig’s linear contact valve disc, the problem has been resolved. To be more specific, I want to know exactly how high the viscosity force has to be in order to cause damage to the valve plates; therefore, I am looking for relevant information. I hope experts can give me some guidance. Thank you again to the guy who replied; may your family be happy and you stay healthy.
