Product Description PRODUCT NAME: No negative pressure Water supply equipmentof LZWIn order to make the equipment performance to be more perfect, We developed a new generation of the network pressure superposed water supply equipment in the original technique based on LZW (III) type pipe network pressure superposed (non negative) frequency conversion water supply equipment.Range of use1. In order to adapt to the social development with the improvement of the living standard and qualit.2. Additive pipe pressure (negative pressure) water supply equipment emerge as the times require, the device makes full use of the municipal pipe network pressure superposition, pressurized water supply, .3. Superposition of pressurized water supply, small occupation of land, energy saving and environmental protection.4. Tank structure superposed pressure (without negative pressure) water supply equipment long time over the municipal pipe network water supply operation condition of water use in the user, because the regulating tank storage capacity is limited, can not guarantee the normal water use of users, as well as the municipal pipe network short water, be no water available to the problem, in order to make the equipment performance to be more perfect, the company in on the base of original technology developed a new generation of the network pressure superposed water supply equipment of BW (III) type pipe network pressure superposed (non negative) frequency conversion water supply equipment.Working conditions1. Environment temperature: 4 Centigrade ~40 Centigrade2. Relative humidity b): <90% (20 Centigrade), outdoor allow 95%, without dew;3. Vibration: <0.5g, vibration frequency 10Hz~150Hz, the maximum acceleration should not exceed 5m/s2;4. Tilt: <5 °5. Frequency: 50 Hz ± 5%;6. Power supply voltage: 380V ± 10%;7. Altitude: Not more than 1000m;8. Equipment operation site should be no conductive or explosive dust, non corrosive metal or gas insulation failure or steam;9. Pressure precision: <0.01Mpa;10. Ressure range: 0~2.0Mpa J);11. Flow range: 0~600m3/hfault phenomenonfailure causeelimination methods 1.No power supply or one or two phase power supply is needed Check all phases of power supply and restore power supply 2.Poor contact of ac contactor and burning of coil Repair or replace contactors can not start3.The power switch is not closed, malfunction or damaged Close the switch and replace it if the power indicator does not turn on 4.Thermal relay trip or damage Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started Water level is too low Put water in the sink The motor burned Repair or replace the motor 1.Line is loose Check wiring and tighten connectors 2.Frequency converter malfunctionCheck the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting.The manual is normal3The frequency converter is damagedRepair or replaceAutomatic transmission failure4.Pressure switch damageRepair or replace 5The pressure transmitter is damagedRepair or replace 6.Switch failureRepair or replacePump non - suction pressure gauge pointer to beat violentlyInsufficient water supply for perfusion, air leakage at the connection between pipeline and instrumentCheck pipeline and bottom valve, refill water diversion. Tighten air leakage The pump consumes too much power Too much flow, impeller wear Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flowAbout LYSON? ESTABLISHED IN THE SIXTIES? ONE OF THE FIRST THROUGH THE ISO9001:2008 DOMESTIC,INTERNATIONAL QUALITY SYSTEM CERTIFICATION? SILVER MEDAL WAS AWARDED AT THE NATIONAL CONFERENCE ON THEAPPLICATION OF SPARK CUP TECHNOLOGY? WIN THE NATIONAL AWARD FOR EXCELLENCE IN CIVILIZATION COMPETITION ? GET THE LC OF THE CHINESE GOVERNMENT
