Steel pipe hydrostatic testing machine
Hydrostatic testing machine instructions: 1, the preparation before the operation 1) check whether water tank water to fill (2) check vertical flat steel tube incision 3. Check the sealing ring are in good condition 4. Check all fasteners are tight, whether there is oil leakage in the hydraulic system As aforesaid, shall be handled, otherwise can't test. 2, operation steps, (1) the sealing ring into steel pipe at both ends, with the incision into a plane. (2) the steel tube into the lifting gear. (3) use lifting gear center position the steel pipe to water injection ports. (4) the main oil cylinder push forward steel tube, from the mouth water baffle stop 0.5 1 cm. 5. Open the pump to the steel pipe with water, filled with so far. 6. Push the steel tube to the damper, stop the low pressure water injection. All landowners crackdown on high pressure water injection system, the road test for pressure values. End stop to high pressure water injection pressure, check no leakage after decompression for steel pipe, the pressure reduced to zero. Pet-name ruby master oil cylinder back, fall in steel tube. 3, matters needing attention 1) test, the equipment shall not stand people within 4 meters on both sides. (2) hydraulic press all device, unauthorized personnel and non-professional personnel shall not operate disassembly and changes
