The completion of three oil and gas recovery units does not necessarily mean that they can be handed over. Whether the inspection process is detailed or not directly determines the foundation for the operation in the following years. Acceptance is divided into two stages: single machine testing and linkage debugging. Only by passing through each stage can problems be avoided.
Single machine testing starts with three actions
During the standalone testing phase, first let the device run without load, listen for any abnormal sounds from the vacuum pump and fan, and check if the start stop logic of the control cabinet is executed according to the settings. Record the no-load parameters again: whether the vacuum degree can reach the set range and whether the time to return to normal pressure conforms to the random file description. A machine that cannot run steadily without load will only exacerbate the problem when loaded.
How to do air tightness inspection
Filling and maintaining pressure in the recycling pipeline is a basic method for air tightness inspection. Fill the system with inert gas to the specified pressure, stabilize it for a period of time, and observe the pressure drop. If the pressure drop exceeds the specified judgment value, it should be checked for leaks in sections. The flange, valve packing, and quick connector are the three most prone to leakage, and applying soapy water to inspect them point by point saves time compared to blindly dismantling and inspecting the entire section. After the leak detection is completed, re press and confirm again, and write the results into the record.
How to arrange linkage debugging
The linkage debugging is scheduled to be carried out under normal unloading conditions at the gas station. Unload a truck of oil and observe the entire process of the device from start-up to shutdown: whether the start-up is sensitive, whether the vacuum degree is stable in the range, and whether the automatic shutdown is set according to the delay after unloading is completed. Observe the oil unloading process two to three times in a row, and record the stable parameter as the acceptance benchmark value.
Condensation and discharge process
Check if the condensate tank has normal liquid collection during debugging, if the liquid level gauge reading is consistent with visual inspection, and if the discharge valve switch is smooth. The detection of non methane total hydrocarbon concentration at the outlet of the device shall be arranged according to local requirements, and the detection report shall be archived as a component of the acceptance data.
Suggestions for archiving acceptance data
Compile the factory inspection report, installation record, airtightness test record, linkage debugging record, and operation training attendance sheet of the device into one set, and have the owner, installer, and manufacturer sign and confirm. This document serves as both a handover certificate and a reference baseline for subsequent maintenance.
| Acceptance process | View key points | eligibility criterion |
|---|---|---|
| Single machine testing | Abnormal noise, start stop logic | Smooth operation and execution according to the set specifications |
| Air tightness inspection | Pressure drop after pressurization | Within the specified judgment value |
| Linkage debugging | Start stop sensitivity, vacuum degree | Stable within the set range |
| Condensation process | Liquid collection, level gauge, discharge valve | Consistent readings and smooth switching |
Frequently Asked Questions
Is it necessary to conduct a working condition test during acceptance?
Suggest doing it. The no-load parameters can only indicate that there is no problem with the equipment itself, and the working condition test can expose issues with pipeline resistance and interface sealing during installation.
What should I do if I find that the vacuum degree is unstable during debugging?
First, check if there are any leaks in the pipeline, then check if the return air passage is unobstructed, and finally check the operating status of the vacuum pump itself. Following this sequence for efficient troubleshooting.
Who is responsible for keeping the acceptance documents?
The owner shall keep the original document, and the installation party and the manufacturer shall each keep a copy or scanned copy. In case of disputes, the original document signed by the three parties shall prevail.
