Embodiment Construction

[0026] The lubricating oil temperature directly affects the oil supply of the lubricating parts, and also affects the bearing capacity of the oil film. The normal oil temperature of a diesel engine should be 90-110 degrees Celsius. If the oil temperature is too high, the viscosity of the oil will decrease and the oil pressure will drop, and a good oil film will not be formed. If the oil temperature is too low, the viscosity of the oil will increase, the fluidity will be poor, and the frictional resistance will increase. increased power loss. Abnormal oil temperature is mainly manifested as too high or too low oil temperature.

[0027] The method for detecting abnormal oil temperature in the lubricating system of a diesel engine is characterized in that:

[0028] Include the following steps:

[0029] a) Detect whether the oil temperature is too high;

[0030] b) Check whether the engine oil temperature is too low.

Abstract

A diesel engine lubrication system engine oil temperature abnormity detection method is characterized by comprising the steps of a) detecting whether the engine oil temperature is too high; b) detecting whether the engine oil temperature is too low. By the aid of the method, engine oil pressure faults can be detected timely rapidly, so that the engine oil pressure faults can be removed rapidly and conveniently.

Description

technical field [0001] The design relates to a method for detecting abnormal oil temperature in a lubricating system of a diesel engine, and belongs to the technical field of engineering machinery. Background technique [0002] The diesel engine lubrication system continuously delivers enough clean lubricating oil to the friction surfaces of all transmission parts to form an oil film when the engine is working, realizes liquid friction, reduces friction resistance, reduces power consumption, and reduces wear of parts to improve engine operation. reliability and durability. According to the different working conditions of each transmission part, pressure lubrication, splash lubrication and grease lubrication can be selected. [0003] If the lubrication system fails, the friction pairs will not be well lubricated, which will increase the frictional heat, aggravate the friction and wear, and even cause serious mechanical accidents such as tile holding and burning. [0004...
