Abstract
A method for detecting an after-gear-engagement traveling fault of a bulldozer is characterized by including the steps: a) detecting an O-shaped seal ring of a coarse strainer; b) detecting an O-shaped seal ring of an oil suction port of a variable-speed pump; c) detecting an oil suction rubber hose of the variable-speed pump; d) detecting the variable-speed pump; e) detecting an oil suction port of a steering pump. By adoption of the method for detecting the after-gear-engagement traveling fault of the bulldozer, a fault position can be judged quickly to improve maintenance efficiency, and fitting precision of all parts can be guaranteed to prolong service life of the bulldozer.
Description
Technical field
The present invention relates to fault detection method of not walking after dozer is put into gear, belong to technical field of engineering machinery.
Background technology
Dozer is Modern Construction and the common apparatus in production, to the maintenance of each building block, ripe in today that technology is growing.The key of maintenance judges trouble location, took equipment that may be relevant with fault often apart in the past, and checked 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.
If there is a set of detection method, the possible position occurred according to fault and the difficulty or ease of maintenance, progressively carry out by detecting step, if certain step eliminates fault, then need not carry out the maintenance of following steps, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide fault detection method of not walking after dozer is put into gear, progressively carry out by this invention detecting step, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
For achieving the above object, the present invention is realized by following technological means:
Dozer is not walked after putting into gear fault detection method, it is characterized in that: comprise the following steps:
A) strainer filter O-ring seals is detected;
B) speed-variable pump inlet port O-ring seals is detected;
C) speed-variable pump oil suction hose is detected;
D) speed-variable pump is detected;
E) steering pump inlet port is detected.
Further:
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step a) comprises, and as strainer filter O-ring seals is good, then proceeds to step b); As poorly sealed in strainer filter O-ring seals, changed.
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step b) comprises, and as speed-variable pump inlet port O-ring seals is good, then proceeds to step c); As poorly sealed in speed-variable pump inlet port O-ring seals, changed.
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step c) comprises, carries out bulge test to oil suction hose, as without damaged, then proceeds to steps d), otherwise changed.
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step d) comprises, and opens and inspect speed-variable pump, as skeleton is intact, then proceeds to step e), otherwise, changed.
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step e) comprises, and detects the whether leakage of oil of steering pump inlet port place, as leakage of oil, changes the O shape circle of steering pump inlet port, and carry out fastening to steering pump fuel sucking pipe clamping screw.
The invention has the beneficial effects as follows: progressively carry out by this invention detecting step, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
Embodiment
Air is sucked in dozer speed-variable pump oil suction line when the reason that the dozer adopt hydraulic power assisted to turn to, braking is not walked after putting into gear may be startup.Speed-variable pump limit oil extraction after starting, limit exhaust, after the air emptying in speed-variable pump oil suction road, the oil pressure that speed-variable pump exports just can be set up.The speed change oil circuit of this type dozer and turn to oil circuit to share a strainer filter, steering pump fuel sucking pipe position is lower, and speed-variable pump fuel sucking pipe position is slightly high.If fuel sucking pipe leaks gas, when after shutdown a period of time, air enters fuel sucking pipe from air leak position, and strainer filter inner fluid flows back to the oil end.When again starting, the speed-variable pump appearance " suction is empty " that position is higher.And the lower steering pump in position due to " inhaling empty " phenomenon not obvious, there is not phenomenon in stays.
This detection method designs according to its structure & working mechanism above-mentioned.
Dozer is not walked after putting into gear fault detection method, it is characterized in that: comprise the following steps:
A) strainer filter O-ring seals is detected;
B) speed-variable pump inlet port O-ring seals is detected;
C) speed-variable pump oil suction hose is detected;
D) speed-variable pump is detected;
E) steering pump inlet port is detected.
Further:
Described dozer is not walked after putting into gear fault detection method, it is characterized in that: described step a) comprises, and as strainer filter O-ring seals is good, then proceeds to step b); As poorly sealed in strainer filter O-ring seals, changed.
