| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which medium excavator models adopt load feedback proportional solenoid 702-21-07311? | This flange load feedback proportional solenoid is specially manufactured for PC200-7 and PC220-7 medium construction excavator hydraulic pump regulator manifold block. |
| Q2 | What difference does load feedback control bring compared with ordinary proportional valves? | It collects real-time hydraulic load signal to adjust pump flow, realize precise power matching and achieve obvious energy-saving effect under mixed digging and loading working conditions. |
| Q3 | What abnormal machine states will appear once this solenoid fails? | Frequent engine stall under heavy rock digging, unstable breakout strength, slow boom and stick action, continuous rise of hydraulic oil temperature and fluctuating pump pressure. |
| Q4 | Is full disassembly of hydraulic main pump required during valve replacement? | No, external flange bolt fixed design supports single-piece quick replacement without splitting the whole pump assembly. |
| Q5 | What structural design prevents signal failure in harsh construction environment? | Thickened braided oil-resistant wire and fully sealed two-pin plug effectively resist long-term dust, vibration and high temperature interference. |
| Q6 | What inspection method can judge the working state of this proportional solenoid? | Detect coil resistance with multimeter within standard range; connect power supply to observe whether the valve spool can produce obvious suction and pressure adjustment action. |
