Single Wellhead Control System

Date: 26 Aug 2009
 ⑴ It is provided with hand pump and petrol tank, can open manually and supply pressure automatically;
    ⑵ The Single Wellhead Control System contains pressure sensors, can set pressure reference point to check pressure of flowline. When the pressure is exceptional or the wellhead is destroyed, and flowline pressure increases above or below the pressure sensors “high” or “low” settings, the system automatically closes the valve by closing inside and releasing pressure. Scope of high pressure adjustment: 3000Psi~6000Psi, scope of low pressure adjustment: 800Psi~2000Psi;
    ⑶ Setting fire protecting equipment: when the environment is above 100℃, the equipment run to cut-off in an emergency;
    ⑷ It Controls oil circuit closed circulation to prevent releasing(expect fire protecting equipment running); Maximum working pressure: 6000Psi. When cut-off don’t operate automatically in exceptional situation, or the valve need to be closed, the system can cut- off manually. High pressure accumulator is used for absorbing thermal expansion pressure and complementing little pressure releasing; Safety valve can prevent system in super high pressure. The system faceplate is installed instrument of safety valve pressure, pipelines pressure, pilot-controlled pressure.
    ⑸ The system has the function of solar automatic pressure complement ,by using several pressure limiters it is also available to follow hydraulic control system pipelines pressure and complement pressure in time.
    ⑹ The system is provided with achieving remote cut-off in an emergency by demand.
