Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 3 and Figure 4, in time discharge for guaranteeing the oil gas in diesel engine crankcase, two deaerators 1 are arranged on cylinder of diesel engine rocker box cover 7, make itself and diesel engine crankcase indirect communication, a part of oil gas in crankcase by diesel engine crankcase inner components clearance leakage in rocker box cover 7.Oil gas is after process is arranged on the filtration of deaerator 1 on rocker box cover 7, machine oil in oil gas is deposited in filter core 20, gas after filtration upwards enters into the injection bend pipe 3 at deaerator 1 top, because injection bend pipe 3 roots are connected intercooler intake duct 61, through the injection of the high-speed gas of the outlet of supercharger air compressor 5, the gas after filtration can be discharged crankcase from the outlet of injection bend pipe 3.By this injection by high-speed gas, this scheme not only can in time be discharged the waste gas of crankcase internal leakage, and diesel engine crankcase pressure can be remained rational negative pressure state, has further guaranteed the Diesel Engine Complete Machine security of operation.
As shown in Figure 9, the deaerator housing comprises three parts, base 19, filter element shell 21, injection bending tube shell 34.As shown in Fig. 7-8, be processed with the mounting hole of deaerator on rocker box cover 7, be fastened by bolt with the base 19 of deaerator housing, the O RunddichtringO is housed between the two, played the effect of sealing oil gas separating device, prevent that oil gas from overflowing; The middle part is filter element shell 21, filter core 20 wherein is housed, filter out machine oil, filter element shell 21 is fixed together by clip 41 with base 19, and by the O RunddichtringO this is played the sealing oil gas effect, the port lid 23 of deaerator 1 inside, filter core 20 and filter core inner housing 26 are merged into filter core assembling, and this assembling can complete dismounting, is convenient to more renew cartridge 20; Top is injection bending tube shell 34, and injection bending tube shell 34 is connected with filter element shell 21 by bolt, and is provided with Sealing such as O type circle etc.; Injection bend pipe 3 roots are provided with opening, perforate on intercooler intake duct 61 housings, and both are connected by the injection connecting hose, connect supercharger air compressor 5 air outlets and injection bend pipe.
Keep certain angle between the axis of injection bend pipe and filter core axis, be advisable with 45 ° to 80 °, can guarantee that like this effect of injection is better, actual angle can be arranged and crankcase volume be determined according to diesel engine.
As Fig. 5, shown in Figure 6, be connected and be connected in same injection bend pipe 3 at the cavity that is positioned at after filter core 20 that all is provided with 1, two of deaerator filter core chamber on two rocker box cover 7.Adjacent two filter core chambeies are connected by connecting hose, and the connection mouth place is fixing by clip 41.
In order to regulate the rate of air sucked in required of injection bend pipe 3, be provided with flow regulator between injection bend pipe 3 and supercharger air compressor 5, can adopt the valve that is arranged on connecting pipeline or is fixed on the pipeline end, preferred implementation is hollow screw plug 33 and the threaded pipe that is arranged at the root of injection bend pipe 3, threaded pipe and hollow screw plug 33 and injection bend pipe 3 axis are consistent, as shown in Figure 10-12.Through hole in the hollow screw plug 33 of the tapered insertion of threaded pipe front end, threaded pipe outer wall and hollow screw plug 33 hole walls keep gap, the housing screw-thread fit of threaded pipe rear portion and injection bend pipe 3.As shown in figure 12, the part that threaded pipe 22 stretches into hollow screw plug 33 is taper, and the screw-in depth of regulating like this threaded pipe can be regulated the gap between threaded pipe and hollow screw plug 33, also namely regulates the flow of high-speed gas.hollow screw plug 33 1 sides are communicated in injection bend pipe 3 openings, the cavity of opposite side, the angle coupling 35 that connects by injection bend pipe 3 roots and connecting tube are communicated in the air outlet of supercharger air compressor 5, high-speed gas from intercooler intake duct 61, enter in injection bend pipe 3 by angle coupling 35, this high-speed gas is entered in atmosphere by the expansion opening of injection bend pipe 3, thereby to the γ-ray emission air-extraction function in deaerator 1, regulate as required the screw-in depth of threaded pipe 22, and then the gap between adjusting threaded pipe 22 and hollow screw plug 33, until reach suitable air displacement.This mode regulated quantity can stablize, change continuously, and threaded pipe and injection bend pipe 3 screw-thread fit, its screw-in depth are difficult for can keeping the gap stable, thereby guaranteeing stablizing of throughput because pine occurs in vibration.
