The transportation of three oil and gas recovery devices to the site is just the beginning, and the installation quality directly determines whether the device can achieve the designed recovery effect. From on-site survey to installation, pipeline connection, explosion-proof wiring, and linkage debugging, there is room for stepping on each link. This article summarizes the high-frequency issues encountered during on-site installation for engineering personnel to compare and self check.
The most common reason for rework is rough on-site survey. The pry mounted device has clear requirements for the installation site: the ground should be flat and able to bear weight, there should be maintenance space around, the distance between the air inlet and the oil tank area should be reasonable, and the exhaust outlet should avoid densely populated areas. During the survey, the pipeline path, cable routing, and explosion-proof area division should be confirmed together, and a floor plan should be drawn before placing an order. Upon arrival, it was discovered that there was insufficient space and conflicting pipelines, which not only delayed the project schedule but also increased costs.
If the condensate in the oil and gas recovery pipeline cannot be completely discharged, it will accumulate at a low point and form a liquid seal, hindering gas circulation. Membrane components and compressors are also afraid of liquid ingress. The pipeline layout should ensure a continuous slope towards the gas-liquid separator, with as few turns as possible, and avoid U-shaped sections; Clean the sealing surface of the flange connection and align the gasket to prevent air leakage. After the completion of pipeline welding or connection, conduct a tightness check to confirm that there is no leakage before connecting the device.
Gas stations are classified as explosive hazardous areas, and electrical connections must comply with explosion-proof requirements: the cable entry device of the explosion-proof junction box must be compacted in place, and excess entry holes should be sealed with plugs; Cable selection, conduit installation, and grounding are all constructed according to the drawings and specifications; Measure the insulation and grounding resistance after wiring is completed. The most important thing in the explosion-proof process is to save trouble. Any loose or poorly sealed part is a hidden danger, and it cannot pass the inspection.
In the debugging phase after installation, many projects only undergo single machine trial operation before being put into operation. The standard practice is to first confirm the correct direction of the pump, compressor, and valve movements by inching them individually, and then coordinate them as a whole, verifying the coordination of each section with data such as oil and gas concentration, system pressure, and processing capacity; During the debugging period, record the emission concentration and recovery efficiency, and confirm that they meet the design requirements before running with oil. Debugging data should be retained as a baseline for future operations and maintenance.
Spend an extra day on self inspection during the installation phase and a month less on firefighting during the operation phase. Only by grasping the four checkpoints of surveying, layout, wiring, and debugging can the device truly demonstrate its design performance.
