What are the hazards of liquid in a reciprocating compressor?
When the liquid hammer is mild, the cylinder may produce abnormal noises (such as knocking sounds) and the cylinder body may vibrate. In severe cases, water hammer can damage the cylinder, as well as cause damage to components such as the piston assembly, connecting rods, crossheads, and valves
Damage to the cylinder causes wear of the cylinder piston rings
Reciprocating compressors must absolutely not have liquid present in them. As mentioned on the second floor, this can lead to abnormal noises at best, damage to the valves, erosion of the cylinder passages, and in severe cases, damage to the cylinder body and piston components. It can also cause leakage of the medium and other associated hazards.
Cylinder knocking, loose back nuts, damaged valve plates, bent connecting rods, damaged bearing shells, and cracks in the head gasket occurred.
Liquid is incompressible; excessive motor power can cause the crankshaft to deform and get damaged over time.
The most common symptom of liquid in the compressor is extremely rapid damage to the gas valves. The newly replaced valve disc broke after just a few days, and even the valve cover suffered wear. In severe cases, it can lead to the breakage of the piston rod (usually at the point where it connects to the crosshead) as well as deformation or even breakage of the connecting rod.
1. Water hammer； 2. Damaged air valve ； 3. Cylinder collision ； 4. Motor overload.
(1) The inlet pipeline generates surge noises and the vibration of the pipeline intensifies. (2) The oil injected by the oil injector gets diluted, leading to accelerated wear of the piston rings. (3) The piston may bend and the piston rings may break. (4) The valve plates become dirty, causing the sealing surfaces of the valves to fail in a short time, and in severe cases the valves may even break
Our company had an incident once where the air valve was completely blown away
Liquid hammer can cause cylinder collision; in severe cases, it may lead to the destruction of the compressor, damage to the cylinder end caps, and serious accidents such as fires and explosions due to the leakage of the medium
