Abstract
A method of monitoring the running state of the compressor link shoe includes the following steps: measuring the temperature of the lubricating oil using a temperature-measuring probe disposed on the inner wall of the compressor spindle box cap; sending the obtained signal into a microcomputer for monitoring by a DCS system to obtain accurately and effectively the running state of the link shoe inside the compressor set and working out a plan of the maintenance outage in advance according to the obtained data, so as to guarantee the safe operation of the machine set within a high limit.
Description
Technical field
The present invention relates to a kind of method of measuring oil temperature monitoring connecting rod bearing shell operation conditions,,, formulate the maintenance and repair plan to evaluate its operating life especially for the heavy-duty comprssor connecting rod bearing shell.
Background technique
The connecting rod bearing shell of piston compressor is made circumference round spindle centerline together because of the pin that is in operation and cranks arm and is rotated, therefore the operation conditions before connecting rod bearing shell being damaged can not the same direct measurement watt back of the body with main axle bush its operation conditions of temperature monitoring, lack a kind of effective monitoring means always, can only simply carry out amplitude measurement and comprehensive diagnos analysis by tank wall to whole headstock, concerning the large-scale compressor group, the main axle bush that relates to is relative with connecting rod bearing shell more, operation conditions that can not the secondary bearing shell of very direct reflection, have bigger difficulty to instructing fault diagnosis and implementing the maintenance scheme, effect is relatively poor relatively.
Summary of the invention
Purpose of the present invention promptly provide a kind of invest less, reflection sensitivity, accurate and effective, can be very intuitively and monitor the operation conditions method of the inner link watt of compressor bank accurately.
The object of the present invention is achieved like this: a kind of method of monitoring operation state of compressor link bushing; by being installed at the compressor main shaft cover wall, a temperature probe tests the temperature of the lubricant oil that connecting rod throws away; the signal that temperature probe obtains enters microcomputer by the DCS system and monitors; under normal operating conditions; the measured load that obtains by temperature probe is a relative stationary temperature curve; when connecting rod bearing shell inordinate wear or bearing metal occur and comes off; can both sensitive reflecting in the temperature that throws away oil; in the case, make the plan or the shutdown maintenance of shutting down maintenance in advance.
The method of monitoring operation state of compressor link bushing provided by the present invention; test the temperature of lubricant oil by the temperature probe that is arranged on the compressor main shaft cover wall; the signal that obtains enters microcomputer by the DCS system and monitors; but accurate and effective, obtain the operation conditions of compressor bank inner link watt intuitively; can make the plan or resolute shutdown of shutting down maintenance in advance according to the data that obtain and overhaul, can guarantee the safe operation of unit to greatest extent.
Embodiment
Working principle of the present invention is as follows: under normal operating conditions; the measured load that obtains by temperature probe is a relative stationary temperature curve; as long as inordinate wear appears in connecting rod bearing shell or bearing metal comes off; can both sensitive reflecting in the temperature that throws away oil; in the case; can make the plan or resolute shutdown of shutting down maintenance in advance and overhaul, can guarantee the safe operation of unit to greatest extent.
Embodiment:
4M40-409/11-BX type compressor is in running; the connecting rod bearing shell damaged condition often appears; and do not find that fault enlarges down to accident late owing to there are the quite good detecting means to cause; adopt after the compressor main shaft cover wall is installed a temperature probe and tested the temperature of connecting rod lubrication oil at the utilization said method; by finding that connecting rod bearing shell damages this some oil temperature fluctuation in early stage and in time shuts down maintenance, repeatedly avoid effectively because of the connecting rod bearing shell bearing metal mechanical amplification accident that the back causes that comes off.
The DCS system is meant digital Distributed Control System, promptly adopts computer system to finish automatic monitoring to the produced on-site process.
Claims (1)
1; a kind of method of monitoring operation state of compressor link bushing; it is characterized in that: test the temperature of the lubricant oil that connecting rod throws away by a temperature probe is installed at the compressor main shaft cover wall; the signal that temperature probe obtains enters microcomputer by the DCS system and monitors; under normal operating conditions; the measured load that obtains by temperature probe is a relative stationary temperature curve; when connecting rod bearing shell inordinate wear or bearing metal occur and comes off; can both sensitive reflecting in the temperature that throws away oil; in the case, make the plan or the shutdown maintenance of shutting down maintenance in advance.
