Abstract
The invention provides a regulating valve sliding wear fault detection method which is characterized by comprising the following steps that 1) whether the system is stable is detected; b) whether contact stress is oversized is detected; c) whether a valve core and a valve body are centered is detected; 4) surface perfection is detected; and 3) conformance of material selection is detected. According to the regulating valve sliding wear fault detection method, a fault position can be rapidly judged so that foundation can be laid for the next step of maintenance, maintenance time can be saved and maintenance efficiency can be enhanced.
Description
Technical field
The present invention relates to variable valve slip wear-out failure detection method, belong to variable valve maintenance technique field.
Background technology
Variable valve is the device controlling flow and regulate pressure in explained hereafter, it is in high temperature, high pressure, inflammable, explosive, poisonous and work under having the conditions such as corrosion, for ensureing that it can run well under severe conditions, skillfully must grasp the various fault handlings of variable valve, process at any time during to have situation.
One of key of variable valve maintenance is quick failure judgement position, to lay the first stone for next step maintenance, saves servicing time, improves maintenance efficiency.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide variable valve slip wear-out failure detection method, can failure judgement position fast, to lay the first stone for next step maintenance, save servicing time, improve maintenance efficiency.
For achieving the above object, the present invention is realized by following technological means:
Variable valve slip wear-out failure detection method, is characterized in that: comprise the following steps:
A) whether detection system is stablized;
B) whether excessively contact stress is detected;
C) spool, valve body whether centering is detected;
D) surface smoothness is detected;
E) whether test material is selected and is met.
Further:
Described variable valve slip wear-out failure detection method, is characterized in that: described step a) comprises, and as system is unstable, improves system stability.
Described variable valve slip wear-out failure detection method, is characterized in that: described step b) comprise, as contact stress is excessive, increase bearing size.
Described variable valve slip wear-out failure detection method, is characterized in that: described step c) comprise, as spool, valve body misalign, spool, valve body are repaired in processing again.
Described variable valve slip wear-out failure detection method, is characterized in that: described steps d) comprise, as surface smoothness is bad, surface of refacing.
Described variable valve slip wear-out failure detection method, is characterized in that: described step e) comprise, as material selection does not meet standard, select better guide and material.
The invention has the beneficial effects as follows: variable valve slip wear-out failure detection method provided by the invention, can failure judgement position fast, to lay the first stone for next step maintenance, save servicing time, improve maintenance efficiency.
