Problems solved by technology

However, the separation effect of the above two respirators is limited, especially after the engine has run tens of thousands of kilometers, the baffle and filter screen of the labyrinth are bonded with a large amount of engine oil or degenerated material of the engine oil, and the effect of the respirator on separating oil and gas is even worse. Difficult to replace parts such as filters

Abstract

The invention provides a high-power diesel engine respirator device, comprising an upper casing, a first middle casing, a second middle casing, a lower casing, an oil and gas inlet pipe, an upper baffle, a middle baffle, and a lower baffle , filter screen, metal ring, rear side plate, the upper shell, the first middle shell, the second middle shell, and the lower shell are sequentially connected from top to bottom to form the overall shell structure of the respirator. air intake channel and filter cavity; the rear side of the overall shell structure is provided with a rear side plate for easy disassembly of the filter screen and metal ring; the bottom of the upper shell is equipped with a filter screen, and the first middle shell and the second An intermediate baffle is set between the two intermediate shells, a lower baffle is set between the second intermediate shell and the lower shell, and a number of metal rings are filled between the intermediate baffle and the lower baffle. The body of the respirator of the invention is filled with a large number of iron or aluminum metal rings, which increases the circulation area of ​​oil and gas and greatly improves the oil and gas separation effect.

Description

Technical field [0001] The present invention belongs to the technical field of engine parts, in particular, relates to a large power diesel engine respirator device. Background technique [0002] When the engine is working, there will be a portion of the flammable mixture and exhaust gas to the crankcase by the piston ring. The exhaust gas pressure of the crankcase is increased, and the oil seal, the crankcase inner liner, etc., Oil steam in the atmosphere will cause pollution to the atmosphere. The engine breathing apparatus is in communication with the crankcase. The respirator can achieve the effective separation of the engine inside and the external pressure, and the oil and gas is effectively separated. The separated oil is returned to the diesel cabinet, and the gas leads to the atmosphere and the degree of pollution is greatly reduced. [0003] At present, the large-power diesel engine respirator application uses a respirator with a labyrinth structure or an in-filter stru...
