BOP test pump control device use, maintenance and lubrication

Therefore, in order to ensure that the blowout preventer control device can effectively, reliably and quickly control the blowout in an emergency situation, the blowout preventer test pressure pump control device is an important equipment that " The relevant personnel must be technically trained so that the management and users understand the structure, know the principle, and will install, operate, maintain, and troubleshoot. Next, a detailed description of the blowout preventer test pump control device use, maintenance and lubrication. 1, Instructions In the case of normal drilling, the remote control station handle the Valve position is: the BOP in the "open" position, put the valve in the "off" position, bypass valve in the "off" position. Driller rotary valve into the second stage of operation, the valve should be used to move the source valve, while pulling the corresponding control valve. As the air pipelines are slender pipelines, it takes a period of response. After turning the handle of the rotary valve, pause for more than 3 seconds to ensure that the corresponding remote rotary valve is completed. The hydraulic or gas lines connecting the control device to the BOP shall not pass through the vehicle to prevent crushing. The control device should be checked once per shift during normal drilling. The inspection contents include: whether the tank level is normal; whether the accumulator pressure is normal; whether the electrical components and circuits are safe and reliable; whether the oil and gas pipelines are missing or not; and pressure control Automatic start and stop of the device and the liquid gas switch are accurate and reliable; whether the pressure gauges are in accordance with the requirements or not; open and close the blowout preventer according to the relevant safety regulations. Users should establish the use and maintenance records, keep records of usage, fault conditions and overhauls. All documents and records must be randomly transhipped. 2, Maintain and maintain the filters on the top of the oil filter and the fuel tank, disassemble after each use on the well, take out the filter screen, carefully clean to prevent the dirt from clogging; Open the bottom of the drain valve once a day, will be stored in the cup of sewage discharge. Remove the filter cup and the water bottle once every two weeks. When cleaning, clean the bottle with mineral oil such as petrol and dry it with compressed air. Do not wash with acetone, toluene or other solutions to avoid damaging the cup. Oil mist device in gas source processing unit: Inspect the liquid level in its cup once a day, pay attention to timely replenish and replace the oil (N32 oil or other suitable oil), and disassemble and wash when it is found that the oil drips poorly. Periodically check the accumulator pre-charge nitrogen pressure. Nitrogen pressure is checked once a week when initially used, and then checked monthly for normal use. When nitrogen pressure is less than 6.3MPa (900psi), it should be replenished promptly. Check that the nitrogen pressure has to be fully relieved with the accumulator bottle. Relieve the pressure by using a ball valve with a drain on the bottom of the accumulator. When controlling the device for long distance transportation, it is recommended that the nitrogen in the accumulator be left at only about 1MPa (140psi) so as to avoid accidents during transportation. Check the fuel tank level at any time, periodically open the bottom of the tank plug the drain, check the bottom sediment, if necessary, clean the bottom. Periodically check the electric oil pump, pneumatic oil pump or manual oil seal packing, packing should not be too tight, as long as no significant oil spill, in case of packing damage should be replaced. When removing the pipeline, care should be taken not to lose the O-ring of the quick-change union. After disassembly, these seals should be collected separately and properly stored. Often wipe the remote console, driller console surface, keep clean, be careful not to touch off all kinds of signs. After each well drilled, the pressure gauge should be checked once. 3, lubrication instructions once a week with a gun to the rotary valve air cylinder two grease nozzle appropriate amount of grease. Once a week to check lubricator lubricants, lack of adequate amount of N32 should be added mechanical oil or other suitable oil. Once a month to check the electric oil pump crankcase oil level, lack of adequate amount of N32 mechanical oil or other suitable oil. Once a month remove the chain guard, check the lubricating oil, lack of adequate amount of N32 mechanical oil or other suitable oil. Through the above BOP pressure pump control device introduction, maintenance and lubrication, I believe you already know how to make better use of blowout preventer pressure test pump.
