Core segmented user demands include zero-modification original equipment installation, stable manual hydraulic pressure regulation, anti-misoperation explosion-proof electric switching, real-time hydraulic oil temperature-liquid level linkage monitoring, leak-free high-pressure fluid conveying, and unified matching spare part procurement to solve BOP block offset deviation, hydraulic loop pressure runaway, explosion-proof circuit switching failure, pipeline oil leakage and motor transmission vibration common onsite electromechanical faults.

1.2 Pre-positioned On-site BOP Working Pain Points Solved

• Generic aftermarket lateral driving block sets produce assembly offset exceeding 0.40mm under 235kN rated BOP hoisting load, causing uneven force on FY50 suspending assembly and abnormal structural torsion

• Ordinary transfer switches lack anti-interference explosion-proof structure, triggering random circuit mis-switching under oilfield electromagnetic field interference, affecting ZKYZ-630II valve group linkage action

• Universal high-pressure hose assemblies develop interlayer delamination after 480 continuous hydraulic working hours, resulting in micro leakage at pipeline joint under 28MPa system working pressure

• Non-matched star delta starters generate unstable starting current, causing frequent overload tripping of ZKYZ630II oil pump motor assembly under low ambient temperature startup condition

2.5 Engineer Verified Maintenance Rules & On-site Avoidance Tips

Clean ZKYZ630II-W1200 oil suction filter impurity every 330 continuous BOP lifting hours; calibrate DY-2000 temperature controller set value every 710 cyclic operation hours; check explosion-proof plug sealing gasket integrity before daily equipment startup; critical avoidance tip: do not mix install 3A,6A graded fuse cores arbitrarily, which will break circuit protection threshold and damage internal explosion-proof electrical modules.
