Abstract
The utility model relates to a labyrinth back cover for a diesel engine. The utility model is composed of a back cover body, a respirator, and an oil baffle plate, wherein, the oil baffle plate is arranged on the back of the back cover body; an oil gas inlet and an oil return port are arranged on the oil baffle plate; a first, a second, a third and a fourth stage oil-gas separating chambers are arranged on the back cover body. A paper pad can be arranged between the back cover body and the oil baffle plate in order to improve the effect of preventing engine oil leakage. The utility model has the characteristics of simple structure, low cost, convenient assembly and disassembly during maintenance, good preventing effect of engine oil leakage, and little possibility of failure occurrence of the respirator. The utility model is especially suitable for being used as ventilating devices on crankcases of 195 diesel engines.
Description
The utility model belongs to the ventilation plant on a kind of diesel engine crankcase.
Crankcase bleeder on the existing S195 diesel engine is contained in by resuscitation apparatus on the gear chamber cover of diesel engine crankcase and constitutes.Owing to structural reason, mounting or dismounting inconvenience prevented the engine oil leakage weak effect, the deficiency that resuscitation apparatus easily breaks down when the ventilation plant on this diesel engine crankcase existed maintenance.
Task of the present utility model is at the existing deficiency of ventilation plant on the existing S195 diesel engine crankcase, provide a kind of simple in structure, cost is low, mounting or dismounting are convenient during maintenance, prevent that engine oil leakage is effective, the ventilation plant on the diesel engine crankcase that resuscitation apparatus is difficult for breaking down---diesel engine labyrinth bonnet.
The utility model is finished as follows: diesel engine labyrinth bonnet is made up of rear cover body (1), resuscitation apparatus (2), oil baffle (3).Wherein oil baffle (3) is contained in the back side of rear cover body (1).On a side on oil baffle (3) top, be provided with oil and gas import (20).Be provided with return opening (19) in the bottom of oil baffle (3).Oil and gas import (20) corresponding part with on the oil baffle (3) at rear cover body (1) is provided with the first order Oil-gas Separation chamber (12) that is made of the first road leakproof oil gluten (11).Be provided with spill port (13) in the bottom in first order Oil-gas Separation chamber (12).Top portion in first order Oil-gas Separation chamber (12) is provided with intake duct (10).Be provided with oil gas isolation bar (17) in the bottom of rear cover body (1).On oil gas isolation bar (17), be provided with spill port (5) down.The bottom of oil gas isolation bar (17) is an oil back chamber (4).The top of oil gas isolation bar (17) is Oil-gas Separation chamber, a second level (16).Be provided with on the opposite side of rear cover body (1) middle and upper part and keep off oily horizontal bar (6), second road by second road and keep off third level Oil-gas Separation chamber (18) and the fourth stage Oil-gas Separation chamber (9) that oily stud (14), the 3rd road leakproof oil gluten (8) constitute, wherein fourth stage Oil-gas Separation chamber (9) are positioned at the top in third level Oil-gas Separation chamber (18).Be respectively equipped with air inlet spill port (7) and following air inlet spill port (15) in the lower end in third level Oil-gas Separation chamber (18) and fourth stage Oil-gas Separation chamber (9).Resuscitation apparatus (2) is contained on the rear cover body (1) at top, fourth stage Oil-gas Separation chamber (9).In order to improve the effect that prevents engine oil leakage, between rear cover body (1) and oil baffle (3), can establish a paper washer.Ventilation plant on this diesel engine crankcase---the working principle of diesel engine labyrinth bonnet is: after the oil and gas import (20) of the oil gas in the crankcase on oil baffle (3) enters the labyrinth in the cover cavity, after the Oil-gas Separation in first order Oil-gas Separation chamber (12), Oil-gas Separation chamber, the second level (16), third level Oil-gas Separation chamber (18), fourth stage Oil-gas Separation chamber (9), gas is discharged crankcase through resuscitation apparatus (2), and the return opening (19) of machine oil on oil baffle (3) flows back in the crankcase.Avoided oil droplet to discharge outside the crankcase like this.
The utility model is compared with the ventilation plant on the existing S195 diesel engine crankcase, has simple in structurely, and cost is low, during maintenance mounting or dismounting convenient, prevent that engine oil leakage is effective, the characteristics that resuscitation apparatus is difficult for breaking down.In addition, adopted the utility model after, can reduce the manufacture cost of crankcase.The utility model is particularly suitable as the ventilation plant on the S195 diesel engine crankcase.
