Pro, specific price please call. (Pump power because sample sizes, the system configuration is not the same, the price is not the same Oh! Welcome customers to call us!) Hanson supply for your dedicated service! Contact: Miss Europe Contact: 159-7414-3465 Online QQ: 1922601218 National Hotline: 400-086-8955 water supply equipment a key regulator control button to trigger a man-machine interface, the program can automatically according to the linkage modify various parameters associated with stress. Simple operation to our customers, complex background processing and linkage to us. Since you no longer have to worry about operational problems. Requires a constant pressure water supply equipment, equipment before using hand pump rotor disc should be no friction, hysteresis phenomenon; 2, with low-voltage 500V plug table detect motor insulation should be 0.5MΩ or more; 3, remote pressure gauge socket 1, 2,3 (yellow, blue, red) were connected to terminals 1, 2. Or measured with a multimeter remote pressure gauge resistance value, the resistance value of the maximum of 1 and 2, the other three, with three small resistance value is 1, and 3 large resistance value is 2. The best detection with a multimeter or else pick the wrong line will burn table; 4, remote pressure gauge should be installed to the user pipe-line, after a mains outlet check valve; 5, control instruments and line no damage; 6, frequency cabinet power transmission, the non-first-mover drive parameters; 7, open the pump discharge valve, excluding gas; 8, the system first starts or maintenance, repairs, should start to open the inlet valve, close the outlet valve; check whether the system has a leak spilled everywhere. If diarrhea should be started after the leak excluded; 9, first check the pump when the pump is turned on automatically, such as reversing the swap any two-phase power line wire line position; then go to manual start of each pump, such as The same pump motor reverse swap lines; 10, one by one manually start and stop the pump, check the pump operation without anomalies; 11, no abnormal state after the device is automatically controlled water supply equipment 1, combined with field test data feedback (no tower frequency of water supply equipment speed, frequency, current, voltage, pressure, etc.) is transmitted to the microcomputer controller, after analysis and judgment, through the unique noise reduction program, the noise reduction of 30-40% on an equivalent energy products to avoid frequency resonance region, eliminating frequency current sound. 2, the transfer of self-sustaining technology, only in exchange pump is running, the control tower frequency of water supply equipment turns the AC contactor pull it off once, usually only when the pump is running inverter, AC contactor is always pull, so both components of action to reduce the control cabinet sounds and greatly extend the life of components. 3, through the automatic control of temperature and humidity sensor inside the fan stops, both to ensure the cooling effect and reduces the control cabinet fans brought the noise.
