Block brick cabin safety pressure bar is commonly used in the safety pressure bar permeable brick, General seamless steel pipes or stainless steel tubing with a diameter of 40-50mm. In the cockpit there is a tilting movement or wobble block brick used more often. Safety pressure bar must have a locking device can not open, mostly with spring bolt lock. Block making machine shoulder to shoulder safety pressure bar safety pressure bar. The pressure bar with a steel pipe, plus flexible packaging, pressure in the passenger's shoulders, mostly used in the cockpit permeable brick factory in Tianjin in the vertical plane rotating Mianshaozhuanji, such as a roller coaster, days turn to turn, meteor hammer (weight loss the oversized Mianshaozhuanji also applied). Pressure bar locking and opening mostly uses hydraulic cylinders to complete. When the solenoid is energized, the cylinder upper and lower chambers in communication, the pressure bar can be opened without electricity, no communication with the cylinder upper and lower chambers, the pressure in the locking bars are still open signal display, if the display is not secured permeable brick factory in Heilongjiang , the power button does not work. Due to this pressure bar used in high altitude more dangerous Mianshaozhuanji, so in addition to the hydraulic cylinder for clamping the outer permeable brick factory peaks should prescribe safety device, such as a spring bolt, ratchet pawl type, etc. to be foolproof. Power element block brick refers to a variety of hydraulic pumps. 1, blade oil pump (including single-stage pumps, variable displacement pump, two-stage pump double pump). 2. plunger pump, is divided into axial piston pumps and radial piston pumps, axial piston pump metering pump , variable displacement pump (variable pump manual is divided into variable and pressure compensation variable servo variable other] from the structure is divided into the end face of the valve type with oil and oily with oil in two ways, and the radial piston pump with the oil type, basically a valve with the oil. 3, gear pumps and tandem pumps (including external engagement with the ring] two structural types. permeable brick factory in Zhengzhou, permeable brick, two-Sheng Machinery by the Zhengzhou Municipal SHUANGSHENG Machinery Manufacturing Limited.
