Installation Key Points:
1.Mount equipment horizontally in dry, ventilated indoor area. Level using vibration isolators—no pre-embedded anchor bolts required. Ensure equipment horizontal deviation ≤2 mm/m.
2.Connect inlet/outlet via flange/thread standard interfaces. Recommend installing flexible rubber joints to absorb pipe stress. Provide independent supports for inlet/outlet piping.
3.Electrical control cabinet junction box faces outward. Route cable in conduit. Grounding resistance ≤4 Ω. Before initial startup, confirm pressure tank pre-charge pressure meets design requirements (typically 70%–80% of system working pressure).
4.Connect dual power supply. Set target pressure via control panel (default 0.3–0.6 MPa). After startup, monitor pressure feedback & pump start/stop logic to confirm constant-pressure accuracy ≤±0.02 MPa.
Commissioning Process: Confirm pressure tank pre-charge pressure → Verify dual-power wiring → Set control panel parameters → Auto pressure stabilization running test → Simulate fire signal linkage test → Record pressure/current/switching time data → Acceptance sign-off.

Q1: How to ensure constant pressure ≤±0.01 MPa at the most unfavorable point of the pipeline?
Uses high-precision pressure transmitter + intelligent electrical control PID algorithm to monitor pipeline pressure in real-time and auto-adjust pump start/stop. Combined with diaphragm pressure tank buffering, tested pressure fluctuation controlled within ±0.01 MPa.
Q2: How does diaphragm pressure tank prevent secondary contamination of fire water?
Uses rubber diaphragm to completely isolate water chamber from air chamber, one-time nitrogen charging & sealing. Water and air never contact, completely eliminating algae/rust/foreign matter intrusion, ensuring fire water quality meets acceptance standards.
Q3: How does dual-power switching achieve ≤3-second response with zero interruption?
Standard dual-power automatic transfer switch (ATS) detects grid fault within 0.5 seconds + completes switching within 2 seconds. Combined with pressure tank buffering supply, tested pipeline pressure fluctuation ≤±0.05 MPa, ensuring zero water supply interruption.
Q4: How is 30-second initial fire-fighting water supply guaranteed?
Built-in ≥150 L fire water storage volume. Pressure tank pre-charge pressure set to 70%–80% of system working pressure. Upon fire signal trigger, pressure tank immediately releases stored water. Tested: ≥10 L/s initial fire-fighting flow provided within 30 seconds.
Q5: What adjustments are needed for high-altitude (>1000m) installations?
Thin air reduces effective volume of pressure tank & motor cooling capacity by ~10%/1000 m. Recommend reserving 10%–15% margin for water storage volume or adding forced cooling fan. Provide actual altitude for custom evaluation.
