|---|---|---|
| Q1 | Which wheel loaders adopt variable pump load feedback solenoid valve 714-07-16730? | This square block load feedback proportional solenoid is specially manufactured for WA350-6 and WA420-3 medium wheel loader hydraulic variable pump regulator oil circuit. |
| Q2 | What core function does this solenoid realize for loader hydraulic system? | It receives ECU electrical signal to adjust pump control pressure, change pump displacement in real time according to shoveling load, balance engine power output and reduce fuel consumption during continuous loading work. |
| Q3 | What abnormal equipment states will occur if this solenoid fails? | Slow bucket lifting & dumping movement, insufficient breakout force, heavy steering operation, unstable pump pressure and continuous abnormal rise of hydraulic oil temperature. |
| Q4 | Is full disassembly of the whole hydraulic pump needed during replacement? | No, this valve is externally mounted on pump valve block; only four fixing bolts and wiring plug need to be removed for direct replacement, low maintenance cost and short downtime. |
| Q5 | What structural design ensures stable signal output under harsh construction environments? | Thickened oil-resistant braided wire + fully sealed special waterproof plug, integral rust-proof alloy valve block, effectively resist long-term construction dust, strong vibration and high temperature interference. |
| Q6 | How to quickly test whether the solenoid coil is damaged before installation? | Use multimeter to measure coil resistance, normal range 13–15 ohms; infinite resistance means coil open circuit, resistance below 10 ohms indicates coil short circuit. |
