Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a scratch-resistant nylon gasket for a pneumatic dry oil pump. Background Technology

[0002] A pneumatic dry oil pump consists of two parts: a pneumatic pump and a plunger pump. The pneumatic pump uses compressed air to reciprocate up and down, driving the plunger pump to also reciprocate up and down, achieving the function of oil intake and discharge and generating oil pressure. During the oil extraction process, the pump barrel of the plunger pump is in direct contact with the metal gasket (such as stainless steel gasket or copper gasket) on the sucker rod. Due to the high hardness of the metal, long-term friction or bending deformation of the gasket under stress can cause scratches on the inner wall surface of the pump barrel. Under high temperature and high pressure environments, the metal gasket is also prone to generating wear debris, further aggravating the damage to the inner wall of the pump barrel, affecting the sealing performance, and consequently, failing to extract oil due to insufficient pressure, increasing maintenance costs and affecting work efficiency.
