1.2 Pre-positioned BOP Operation Field Pain Points Solved
• Generic aftermarket star delta starters generate starting current surge exceeding 58A under 240kN BOP lifting load, burning low-voltage contactors in ZKYZ-630II explosion-proof electric cabinet
• Ordinary overflow and relief valves fail graded pressure unloading, causing J2K-160 cycloid hydraulic system pressure surge up to 33MPa, damaging gear pump internal mating parts
• Common non-explosion-proof electrical components suffer dust and hydrocarbon gas erosion, triggering intermittent circuit disconnection in Zone1 oilfield hazardous operation areas
• Universal filter elements have low dirt holding capacity, blocking oil suction loop within 320 working hours and leading to BYT201 oil pump motor oil starvation heating fault
