3: Summarization of the machine
Structure of the main machine:the equipment is single pipe test mode,horizontal test bed ,double beams structure,top in and top out. The fill head adopts double nuts-lead screw model and is driven by a hydro-motor to move in a short stroke smoothly. The venting head adopts hoop-pull rod model and is driven by a oil cylinder to move in a big stroke step by step.
Water system: including low pressure water system and high pressure water system.
Low pressure water system: including water filling system and water flushing system. For the water filling system, there is a filling tank which is used to contain the 3% water emulsion and fill it to the test pipes. For the water emulsion, there is one set centrifugal pump which is used to suck the industrial new water to flush the inner wall of the pipe. The two water systems are recycled.
High pressure water system: mainly including one set sustained intensifier,one set high pressure releasing valve station and one set high pressure one-way valve stations. When testing, the sustained intensifier builds up the pressure quickly and reaches the pressure to the set value precisely and holds it. Test pressure accuracy is within 0-2%.
Sealing mode: adopting big clearance radial sealing.
