Large flow pneumatic pressure test pump BOP remote control device

Control device is an important device for controlling wellhead blowout preventer group and hydraulic throttling valve and well killing valve, and is an indispensable device for preventing blowout during drilling and workover operations. Therefore, whether the control device can be used properly and Maintenance is very important to the control unit. Here to introduce the next large flow pneumatic test pump blowout preventer control device. Remote console by the base, fuel tank, pump, accumulator group, manifold, all kinds of valves, meters and electrical control box and other components. The main function of the remote console is to generate high pressure control fluid from the pump set and store it in the accumulator bank. When it is necessary to open and close the blowout preventer, the high-pressure control fluid from the accumulator is distributed to each control object (blowout preventer) through the three-way four-way rotary valve of the manifold. Driller Console The Driller Console is usually mounted on a rig floor to allow the driller to remotely control the blowout preventer. In order to ensure reliable operation of blowout preventer group, the driller's rotary valve are used two levels of operation, that is, first of all to turn the gas source rotary valve, connected to the gas source, at the same time pull the control gas valve, Can make the corresponding control object move. Air Piping An air duct is used to connect the air line between the remote console and the driller's console. The air cable is composed of a sheath and a plurality of dies. A connecting flange is arranged at the two ends of the air cable respectively connected with the remote console and the driller's console. The connecting flange is sealed with a rubber gasket. Hydraulic Lines In general, the distance between the remote console and the wellbore blowout preventer set is 30 m, requiring a series of hydraulic lines to connect them. There are hard-wired connections and hose connections. Hard lines include pipe rack, closed bend, three elbows and so on. The use of hard pipe connections, with safety, reliability, etc., the disadvantage is that the layout is not easy to install. Flexible hose connection has the advantages of simple, convenient, but in use should pay attention to its safety. According to the scene, you can also mix soft and hard pipelines, give full play to their respective advantages. Alarm Unit The Remote Console can be fitted with an alarm unit that monitors accumulator pressure, source pressure, tank level and motor pump operation. When the above parameters exceed the set alarm limits, the remote console and driller The console gives a sound, light alarm signal, prompting the operator to take measures. The operator should make use of the information provided by the alarm device and the information provided by other instruments to comprehensively analyze the working status of the equipment so as to ensure the reliable operation of the surface blowout preventer control device. Nitrogen Standby System The nitrogen stand-by system consists of a number of high-pressure nitrogen cylinders connected to control manifolds to provide emergency auxiliary energy for control manifolds. The nitrogen backup system is connected to the control manifold via isolation valves, check valves and high pressure ball valves. If the accumulator and / or pump unit does not provide enough power for the control manifold, a nitrogen back-up system can be used to provide high-pressure gas to the manifold to shut down the blowout preventer. The connection of the nitrogen back-up system to the control manifold prevents the pressure fluid from entering the nitrogen back-up system. Nitrogen should be avoided from entering the accumulator circuit during operation. The nitrogen back-up circuit is designed with a bleed control valve to control the discharge of high-pressure nitrogen to prevent high-pressure nitrogen from entering the tank. The spare nitrogen system can also charge the accumulator. Pressure compensation device Pressure compensation device is the ground BOP control device supporting equipment. During drilling, pressure buildup can occur in the hydraulic system as the drill pipe connector passes through the annular blowout preventer. The installation of the device in the ring control BOP pipe, pipeline pressure fluctuations will be absorbed immediately, thereby reducing the annular blowout preventer plastic core wear, but also in the adapter after the plastic core quickly reset to ensure that Drilling safety. The pressure compensation device is installed in the control loop of the BOP control device. To ensure the operation effect, the pressure compensation device should be installed on the closed oil circuit pipeline close to the annular blowout preventer. The above is Xiaobian carefully arranged on the large flow pneumatic test pressure pump blowout preventer remote control device, I believe we have a deeper understanding of it, through the above introduction hope to help you follow up the correct use and maintenance Large flow pneumatic pressure test pump.
