How to do the daily inspection of the three oil and gas recovery devices? Direct answer: On a daily, weekly, and monthly basis - check the meter, listen to the sound, smell the smell, and check for leaks every day, clean the filter element and seal it every week, measure the recycling efficiency every month, tighten the interface, and create a ledger. The essence of inspection is to use low cost to detect problems early, and to investigate again when the alarm sounds. Often, one cycle of collection has already been lost or the compliance red line has been crossed. The criteria for judgment are whether the three actions are closed loop: found, recorded, and disposed of. This article explains the checklist and record criteria for the three-layer inspection in one go. Many sites treat inspections as if they were just passing by, leaving at a glance, only flipping through records when they fail the inspection, only to find that nothing has been written, resulting in a white inspection.
The oil and gas recovery device is an environmentally friendly equipment that operates continuously, and the working conditions are constantly changing: the filter element gradually clogs, the seal slowly ages, and the refrigerant dosage quietly decreases. These will not suddenly sound an alarm, but will be alerted by a slow decline in recovery rate. The value of daily inspections lies in stopping the slow decline before it suddenly exceeds the standard. A common misconception on site is that if the equipment does not alarm, it should not be viewed. As a result, during an environmental inspection, the concentration exceeded the standard, and upon tracing, it was found that the recovery rate had dropped by 20% without anyone noticing. Inspection records are still proof of compliance for future reference. Environmental inspections require daily operation and maintenance traces, so don't wait until the inspection time to supplement them.
Conduct daily inspections to detect four sensory signals: check if the pressure gauge and temperature gauge values are within the normal range, if the pressure gauge falls outside the threshold, and if the condensation temperature is too high, which are early signals; Listen to whether there is any abnormal noise, sharp sound or impact sound from the fan and vacuum pump, indicating bearing or pump head problems; Smell the scene for any oil odor. If the oil odor becomes stronger, it indicates a leak or incomplete collection; Check for oil stains and leaks at the pipeline interface and quick connector, as most leaks occur at the interface location. These four actions add up to no more than ten minutes, but most of the abnormal signs can be detected on the same day. Record and report any abnormalities first, do not run with a problem.
Add three items to the weekly inspection on a daily basis: clean or replace the intake filter. If the filter element is clogged, the pressure difference will increase first, and the collection efficiency will decrease later; Check the condition of seals and gaskets, and replace them in a timely manner if they have aged or cracked; Verify the readings of the pressure gauge and sensor, and compare them with a portable gauge to confirm that there is no drift. These three measures are all preventive actions that require maintenance time and save on subsequent replacement and production costs. For stations with water and dust conditions, the frequency of filter cleaning should be higher than that of dry conditions, and the pressure difference trend should be determined instead of a fixed calendar, which is more in line with reality.
Monthly inspection is a key round of quantification: measuring the trend of recycling efficiency and emission concentration, and comparing it with the baseline to see if there is a step like decline; Tighten all pipeline interface bolts to prevent long-term vibration loosening; Perform a soap water re inspection of the leakage point; Summarize the anomalies and their resolutions for the current month in the ledger. The answer for this monthly round is whether the overall device is healthy or not, relying on data comparison rather than visual inspection. Before and after replacing the adsorbent or changing seasons, monthly testing should be intensified and not follow the usual pace.
| Hierarchy | Action | Follow the signal | handle |
|---|---|---|---|
| every day | Look at the watch, listen to the sound and smell, check for leaks | Pressure, temperature, odor, leakage marks | Record the abnormal operation of forbidden band disease |
| Every week | Filter element calibration sealing ratio instrument | Differential pressure drift seal aging | Maintenance and replacement without delay |
| Monthly | Efficiency testing, fastening interface re inspection | The recycling rate is declining | Archive and encrypt monitoring |
| seasonal transition | Seasonal additional inspection items | Condensation antifreeze and temperature zone | Early screening of patients |
Remember to be able to reproduce the anomaly: date, detected signal, disposal action, and re examination result should not be omitted; Writing efficiency and concentration values into the ledger on a monthly basis is what environmental inspections require, and missing records are equivalent to white patrols.
We can't think like this: slow decline in recovery rate and slow aging of seals will not immediately trigger an alarm, and when the alarm is triggered, it often exceeds the standard; Inspection is to stop these silent hidden dangers before they become accidents.
Check the trend of pressure difference: the filter element clogs quickly under the working condition of water and dust, and the pressure difference is not replaced according to the calendar; Clearing the pressure difference alarm again has already reduced efficiency, and preventive cleaning is more worry free than remedial measures afterwards.
