Abstract
The invention provides a method for detecting the fault that a dump truck gear pump operates while a compartment is not lifted. The method is characterized in that the method includes the following steps that a, the direction of turning of the gear pump is detected; b, whether a distribution valve rod is operated to be in place or not is detected; c, a one-way valve is detected; d, a hydraulic pipe is detected; e, a hydraulic cylinder is detected. By conducting the detection steps step by step, the fault portion can be judged quickly, overhauling efficiency is improved, the matching accuracy of all components can be guaranteed, and the service life is prolonged.
Description
Technical field
The present invention relates to the running of dumping car gear type pump but compartment not lifting fault detection method, belong to engineering detecting service technique field.
Background technology
Dumping car is Modern Construction and the common apparatus in production, to the maintenance of each constituent elements, 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 method of inspection, 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 the running of dumping car gear type pump but compartment not lifting fault detection method, 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:
Dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: comprise the following steps:
A) detection of gear pump rotation direction;
B) whether detection distributing valve valve rod is handled and is put in place;
C) check valve is detected;
D) hydraulic tubing is detected;
E) hydraulic actuating cylinder is detected.
Further:
Described dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: described step a) comprises, and as gear type pump rotation direction is reverse, changes gear type pump.
Described dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: described step b) comprises, as distributing valve valve rod is handled not in place, and adjustment distributing valve gear.
Described dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: described step c) comprises, and check valve loose or dislocation plugs pipeline or occurs abnormal, reinstalls check valve.
Described dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: described step d) comprises, as aging in hydraulic tubing or damaged, is changed.
Described dumping car gear type pump operates but compartment not lifting fault detection method, it is characterized in that: described step e) comprises, as hydraulic actuating cylinder has fault, is repaired or change.
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.
Detailed description of the invention
Gear type pump operates but compartment not lifting, the most direct reason of this situation is exactly oil pressure deficiency, according to the maintenance complexity of the possibility size and parts that cause oil pressure deficiency factor, progressively, parts order from simple to complex little to possibility greatly by fault generation probability possibility is overhauled.
