Abstract
A method for detecting a powerless material pushing fault of a bulldozer is characterized in that the method comprises the following steps that a, an air filter element is detected; b, a diesel filter element is detected; c, the air compressor end of a booster and an air inlet connection hose are detected. By the adoption of the method for detecting the powerless material pushing fault of the bulldozer, the fault cause can be quickly and accurately detected out, and the basis for further overhaul is provided.
Description
Technical field
The design relates to the unable fault detection method of dozer pusher, belongs to technical field of engineering machinery.
Background technology
Engine is the propulsion system of dozer, for dozer provides power, is the key position of dozer.Supercharger is that the energy band dynamic pressure mechanism of qi blade utilizing the waste gas of engine to discharge compresses the air entering air intake duct, improves burning quality increase power to increase air inflow.Engine capacity with supercharger can improve 20% ~ 30% (engine constancy of volume) therefore supercharger break down very large to the dynamic effect of diesel engine.
The maintenance of each building block of engine, ripe in today that technology is growing.The key of maintenance, is judge failsafe position, takes the equipment relevant with fault often apart, check one by one during maintenance.This not only have impact on overhaul efficiency, the more important thing is, the dismounting repeatedly of mechanical part, affects its quality of fit and tenure of use.
Summary of the invention
According to above-mentioned requirements, the object of this invention is to provide the unable fault detection method of dozer pusher, quick and precisely to detect failure cause, for further maintenance provides foundation.
For achieving the above object, the present invention is realized by following technological means:
The unable fault detection method of dozer pusher, is characterized in that: comprise the following steps:
A) air filtering core is detected;
B) diesel-oil filter element is detected;
C) supercharger air compressor end and air intake duct connecting hose is detected.
Further:
The described unable fault detection method of dozer pusher, is characterized in that: described step a) comprises, as air filtering core is dirty, and cleaning or replacing.
The described unable fault detection method of dozer pusher, is characterized in that: described step b) comprise, as diesel-oil filter element blocking, cleaning or replacing.
The described unable fault detection method of dozer pusher, is characterized in that: described step c) comprise, supercharger air compressor end and air intake duct connecting hose pipe collar loosen, and are clamped by pipe collar.
The invention has the beneficial effects as follows: the unable fault detection method of dozer pusher provided by the invention, quick and precisely to detect failure cause, fix a breakdown in time.
Embodiment
Dozer occurs suddenly that pusher is unable in use, engine over-emitting black exhaust.Analyzing reason may be that air inlet is not smooth, or diesel-oil filter element blocking.So take air filtering core lid apart to check air filter, air filter is clean, cleaning or replacing.To dismantle diesel-oil filter element, as blocking, clean and change.Whether careful inspection supercharger air compressor end and air intake duct connecting hose pipe collar loosen, and whether flexible pipe has gas leak phenomenon.If any, test run after pipe collar clamping.Analyze reason: be pressurized air by the known air entering air intake duct through supercharger air compressor of the principle of work of supercharger, after pipe collar loosens, pressurized air all can not enter air intake duct, Partial shrinkage air is missed, and the tolerance of supply engine burning is not enough, and diesel oil does not have Thorough combustion.Here it is engine over-emitting black exhaust, and pusher is unable.This fault of general judgement is exactly that supercharger can not just break down suddenly in use from air inflow and oil circuit analysis, and first dimension opens and inspect air filter and bavin filter, does not check supercharger.Although but this is supercharger part glitch is a typical example to supercharger and engine power relation.
More than show and describe the ultimate principle of the design, principal character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and instructions; under the prerequisite not departing from the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
