Water supply equipment located the house to pass a good buy equipment to Germany

No negative frequency pump function without negative pressure device and municipal pipe network directly connected, does not produce any negative impact on the network when the device is working, through the microcomputer control system equipment and the steady flow compensation system to work effectively with vacuum suppression systems, time automatically adjust and adapt automatic monitoring, automatic compensation for preloading of suction, which can eliminate the influence of the negative pressure and suction pump is running, it will not affect the municipal pipe network in and around the water users, and never will the duct appeared negative. No negative frequency pump field manual / automatic operation conversion device provides the user with multiple operating mode, the device control panel with manual and automatic control mode, the "manual / automatic" switch on the control panel to select. When you select automatic operation, and "start and stop" switch twist to the start position, without human intervention operation of equipment, equipment fully automatic operation in accordance with the procedures set under computer control. No negative frequency water pump ON / dry shutdown When the municipal pipe network water is not met, the device automatically adjust the water supply situation, change the device running the curve, vacuum suppression and steady flow compensation, water conditions and in line with the water situation, When the maximum amount of compensation for municipal pipe network can not meet the needs, the device automatically shut down to prevent damage due to lack of water and equipment. When the municipal pipe network back to normal state, the device automatically. No vacuum pump - automatic voltage function according to the actual situation of the project, the water pressure can set the scene equipment, control system operation speed, time detection of water pressure compared with the set pressure, automatic adjustment, resorted to water pressure is very constant. No negative frequency automatic pump frequency conversion and timing of switching when a water pump at full speed when still can not meet the water, the device automatically control other pumps in operation, and the efficient operation of the pump is always in the state; when a pump is running for a long time , the device can be automatically regulated to other pumps working, effective control of the pump running time, so that the utilization of each pump tends to equal, to avoid pump efficiency pump damage caused by the imbalance, which greatly extend the life of the equipment. No negative frequency automatic compensation booster pump pipe network enabled devices directly connected in series with the water pipe network, make full use of existing water pipe network pressure. Using frequency control technology for water inlet and outlet pressure set pressure to compensate for the difference between the full use of municipal pipe network pressure, energy efficient. No negative frequency pump failure alarm and processing functions when the device is in operation, overcurrent, overload, overvoltage, when the situation is not suitable for the device to work in phase, thermal, voltage, etc., the device can automatically switch to cut protection state to protect equipment from damage. Meanwhile device automatically skips the faulty circuit or pump, into other circuits or pump, to avoid unnecessary equipment downtime affects water users, while an alarm signal, by nearly control, remote control and on-site troubleshooting control site or remote. Alarm no negative frequency pump inverter alarm is automatically reset after the drive is automatically reset three times, and the reset interval increments. If still unsuccessful inverter reset three times, then the automatic shutdown protection. No negative frequency pump automatic data storage device with automatic data storage function, the device has a memory, data storage capacity, has 1024KB of data storage, real-time operating data recording apparatus 16384, to facilitate historical data viewing. You can record the amount of data two months and has erased the recording cycle characteristics of run-time parameters for automatic tracking storage, especially for the operating parameters are stored under fault conditions, the device can automatically store more than five times the detailed fault information, automatically adjust the parameters according to the operating conditions for maintenance testing. No negative frequency pump Application (1) non-negative frequency pump construction, expansion and renovation of residential buildings, residential quarters, office buildings and so on; (2) non-negative frequency pump hotels, restaurants and so on; (3) non-vacuum Lead Pump schools, military units, offices, dormitories and other water-intensive situations; (4) non-negative frequency pump hospitals, shopping malls, convention centers, stadiums, public bathhouses and other public places; (5) no negative frequency pressure water pump Cities fire hydrant water supply system can not meet the automatic flame extinguishing systems or fire water water requirements; the large flow (6) non-negative frequency pump large factories, booster pump station, the development zone and other centralized water supply; (7) non-negative frequency pump industrial and mining production, domestic water; (8) non-negative frequency Pumps circulating water system. If you are the noise generated by the use of water supply equipment fret, or intend to buy a new water supply system installed there is not enough space for installation.
