Waldo Water Supply Changde, Yiyang life low noise frequency of water supply equipment water supply equipment. Factory direct, quality assurance. 150-7312-7301 China Yiyang are efficient low-noise supply equipment Features Digital control: internal operating procedures in the dominant position of the entire water supply system, replacing traditional relay control law, the failure rate is greatly reduced. Electrical components (AC contactor) self-holding function, startup and sleep longer in the frequency control via an external handover suck - off - suction pump operation to achieve control and stop. But through the whole digitizing software to start and stop the pump output abort. Greatly increasing the life of electrical components and lower control cabinet impatient tone. Changde life conversion water supply equipment layout optimization - Chinese are highly efficient inverter control system Each product undergoes stringent control system design and installation layout for each frequency control system, designed to focus on the entire system can best embody the key to product quality. For frequency control system, electrical design engineer should design in the following aspects. 1, frequency control system schematic design 2, the circuit design of the main road. 3, the circuit control loop design. (Including conventional control circuit). 4, PLC control interface circuit. 5, the inverter networking. 6, the frequency control cabinet process design. (Including electrical process design). 7, the cabinet sheet metal process design. 8, anti-jamming design. 9, dust and moisture-proof design. Waldo Changde life conversion water supply equipment installation and maintenance of a living frequency of water supply equipment installation should choose a well-ventilated, dust, wet grounds, ambient humidity -10 ℃ -40 ℃. Should fortification in the outdoor rain, lightning and other facilities. 2, to facilitate the life of frequency of water supply equipment installation, maintenance, equipment should stay around 70cm space, manholes should be retained 1.5m space, surrounded by floor drains should be located. 3, the selected frequency of water supply equipment life venue, handle the foundation, with concrete pouring masonry or masonry tanks. Base to be completely cured, and then lifting the tank and put the stability of the subsequent installation accessories, power. 4, before the test, you should turn off the water supply valve, check water supply equipment life, the sealing valve does not allow leakage phenomenon, driving, steering pump should be noted. When the pressure gauge pointer to the upper limit, the pump automatically stops. Open the water supply valve to the normal water supply, for regular water supply, the selector switch to the manual position. 5, Living frequency of water supply equipment pump unit should be inspected regularly, regular maintenance and add oil. Centrifugal pumps and check valves found leaking, tighten the flange bolts should be timely replacement of asbestos or root, check the pump foot bolt is not loose, to prevent damage to life, water supply equipment. 6, Living frequency of water supply equipment system, should be waterproof, dustproof, always check the insulation of the line, connecting bolts are loose and fuse is good. External pressure gauge with a transparent wrapping material to prevent damage to the water supply equipment life. 7, the tank is found off patent, it is timely painting and maintenance to extend the life of frequency of water supply equipment life.
