Description
Technical field
The utility model relates to Diesel Engine Technique Field, and the diesel engine oil amount control device of mobile purposes is particularly arranged.
Background technique
The small-sized air-cooled single cylinder diesel of present mobile purposes, starting upgraded stroke is big, and it is insufficient, seriously polluted to burn; When diesel engine turns round at declared working condition, diesel engine speed can reduce after external load strengthens suddenly, speed regulator centrifugal force reduces, because the primer spring rigidity of oil-flow control apparatus is little, the oil mass shift fork is under the effect of governor spring power, by governor control characteristics operation, moment of torsion increases rapidly, fuel delivery too much causes burning insufficient, and is serious even flame-out; With rigidity fuel-flow control device, the torque reserve of diesel speed characteristic does not reach requirement, and starting difficulty, can not satisfy the speed characteristics requirement of different operational situations well.Therefore need the supporting oil-flow control apparatus that can both satisfy corresponding requirements at starting and operation process.
Summary of the invention
The purpose of this utility model is to provide a kind of diesel engine oil amount control device, make diesel engine when starting, have the enriching of startup function to solve bad startup problem, and the function that when loaded-up, has control oil mass and torque correction, reduce diesel fuel consumption, reduce discharging and pollution.
The technological scheme of technical solution problem is, comprise adjustable stem, cylindrical housings with the level, the correcting spring seat, primer spring, correcting spring, adjust plug screw, cylindrical housings is established screw thread at step small end cylindrical, be provided with step hole in the housing, convex is established at the adjustable stem middle part, convex is corresponding with the step hole position of housing, adjustable stem one end cooperates with the aperture of housing and stretches out outside the macropore, the correcting spring seat is located in the housing step place macropore, adjust plug screw and be provided with step, the outside thread of adjusting plug screw interior edge face place is connected with the internal thread of macropore one end of housing, between correcting spring seat and adjustment plug screw step, establish primer spring, between adjustment plug screw interior edge face and adjustable stem convex, establish correcting spring, primer spring, the correcting spring sky is enclosed within on the adjustable stem, primer spring outside, correcting spring is interior, it is characterized in that, adjust plug screw and be provided with the endoporus that cooperates with adjustable stem, adjustable stem cooperates with adjustment plug screw endoporus and stretches out and adjust the plug screw endoporus, be provided with groove in the exterior edge face of adjusting plug screw, in groove, be provided with convex parts, establish outside thread near the adjustable stem end of adjusting plug screw, establish regulating handle near the adjustable stem tail end, the internal thread on the regulating handle cooperates with outside thread on the adjustable stem.
Described convex parts is a steel ball.
On the described adjustment plug screw and the outside thread place between the housing establishes tightening nut.
Described adjustable stem end thread place establishes nut.
Beneficial effect is compared with existing diesel engine oil amount control device, be provided with the endoporus that cooperates with adjustable stem owing to adjust plug screw, adjustable stem cooperates with adjustment plug screw endoporus and stretches out and adjust the plug screw endoporus, establish outside thread near the adjustable stem end of adjusting plug screw, be provided with groove in the exterior edge face of adjusting plug screw, be provided with the ball type convex parts in groove, the adjustable stem end is established regulating handle, and regulating handle is established tapped hole and cooperated with outside thread on the adjustable stem.Before diesel engine starting, rotate about 90 ° of regulating handle, regulating handle compresses convex parts, make the adjustable stem the other end leave speed regulating mechanism on the diesel-engine body, this moment, oil-flow control apparatus did not play adjusting and control action, diesel engine normal starting, treat to rotate about 90 ° of regulating handle again behind the diesel engine starting, adjustable stem resets under the effect of primer spring, makes adjustable stem play the effect of control oil mass when the diesel engine proper functioning.
Because on the adjustment plug screw and the outside thread place between the housing establishes tightening nut, correcting spring has pretightening force, by tightening or unclamping the adjustment plug screw and adjust the pretightening force size, and adjust the size of correction stroke with respect to the position of handle by adjusting adjustable stem, adapt to different speed regulating mechanisms, different correction oil mass and the different correction stroke of fuel-flow control device, can adjust easily, tighten tightening nut after adjusting to pin handle, to keep the accurate control function of oil-flow control apparatus.
Because the adjustable stem end thread is provided with nut with matching, after adjusting to accurate position, regulating handle locked, prevent that regulating handle from becoming flexible because of vibration even throw off in the diesel engine operation process, thereby the normal work of influence has guaranteed the reliability of oil-flow control apparatus.
