Tank pump integration equipment Specifications: 1, water flow 0-1500 M3 / H head 2, the control motor power 0.75 --- 1500KW 3, the number of households 10-10000 household water supply 4, the pressure control range 0.15-1.6MPa 5, the average saving rate of 30-60% 6, control theory sine wave PWM or space vector SVPWM 7, a single pump or multiple pump operation mode automatically switches 8, programmable control and PID control 9, 10 60 seconds 150% overload protection function soft start, over-voltage, phase, in effect, under voltage, circuit, instantaneous power failure, short circuit, etc. are self-diagnosis display and protection. Tank pump integrated equipment use and maintenance: 1, constant pressure water supply equipment should choose a well-ventilated, dust less, do not wet the site, environmental humidity -10 ℃ -40 ℃. Should be fortified in the outdoor rain, lightning and other facilities. 2. To facilitate the equipment around the installation, maintenance, equipment, space should be left 70cm, manholes should be retained 1.5m space, surrounded by floor drains should be located. 3. After selecting the venue, properly handle the foundation, with concrete pouring or masonry tank bearing seat. After the base is fully cured, then lifting the tank and put stability, followed by installation accessories, power. 4, before the test, you should turn off the water supply valves, check valves of the seal, does not allow leakage phenomenon, after driving, you should pay attention to the steering pump. 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, you can pull the selector switch to the manual position. 5, the device 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 can not loose foot bolts to prevent damage to the machine. 6, electrical automatic control system, should be waterproof, dustproof, always check the wiring insulation, connecting bolts are loose and the fuse is good and so on. External pressure gauge is best to use a transparent material wrapped to prevent damage. 7. paint off the tank if found, should be promptly painted maintenance to extend the life of
