1, hwɛ sɛ ebia power wiring no yɛ ON:
Hwɛ connectors na ne wiring connection no yɛ powered on ne supply voltage, adjusted to normal position range sɛ ebia desoldering, coil to coil short circuit welding, replacement coil adwuma differential pressure, differential pressure, fluid temperature is too shive, anaasɛ replace solenoidoid valve commensurate nsakrae a ɛyɛ solenoid valves a ɛma nsu no mu valve no yɛ valve a ɛma valve no yɛ valve. Sɛ nsɔano no sɛe a, sesa nsɔano no na fa filter no hyɛ mu.
2, solenoid valve no ntumi ntoto mu bere a ɛwɔ adwumam no:
Seal no si ananmu Sɛ main valve core anaasɛ moving iron core no asɛe, sɛ nsuo hyew ne viscosity no yɛ kɛse dodo a, solenoid valve no a wɔde besi ananmu no yɛ valve core no mu efĩ a ɛkɔ solenoid valve no mu anaasɛ dade core a ɛkɔ so no, spring ayɛ anaasɛ deformation, nkwa hia sɛ wɔsesa, orifice balance hole blockage, adwuma mpɛn dodow a ɛyɛ kɛse dodo, ma products update.
