Problems solved by technology

[0003] There is no protective device to prevent the sealing and plugging of the traditional cylinder block oil passage orifice, which has the following disadvantages: During the use of the engine, the cylinder block oil passage is under the action of long-term alternating pressure and vibration, and the sealing plug may fall off Hidden danger, if the seal is blocked and falls off, the oil pressure of the lubrication system will drop sharply instantly, and the various motion pairs of the engine are easily burned out due to poor lubrication, which will cause serious safety accidents and affect the normal operation of the engine

Abstract

The invention discloses an engine seal plug protection structure. The engine seal plug protection structure comprises a pressing plate located above an air cylinder and a pressure head connected withthe pressing plate and inserted into an oil duct hole of an air cylinder body to lock a seal plug. The bottom surface of the pressing plate is attached to the top surface of the air cylinder body. Moreover, a locking piece is arranged between the pressing plate and the air cylinder body and used for locking the pressing plate. The invention further discloses an engine seal plug protection method.Through the engine seal plug protection structure and protection method, the seal plug can be effectively prevented from falling off, normal operation of an engine lubrication system is guaranteed, and the engine seal plug protection structure is safer and more reliable in the operation process of an engine.

Description

technical field [0001] The invention relates to the technical field of engine oil passage sealing, and more specifically relates to an engine seal blockage protection structure and protection method. Background technique [0002] The sealing plug is a kind of plug installed at the openings of various pipelines of machinery. The interference assembly method is adopted between the openings of the pipelines. When assembling, it is knocked into the inside of the openings of the pipelines, so The pipeline acts as a seal. Due to the simple structure, low cost and easy assembly of the sealing plug, it is also widely used in the oil passage orifice sealing of the engine cylinder block. [0003] There is no protective device to prevent the sealing and plugging of the traditional cylinder block oil passage orifice, which has the following disadvantages: During the use of the engine, the cylinder block oil passage is under the action of long-term alternating pressure and vibration, an...
