Z-proof single-stage pumps are direct-coupled centrifugal pumps are widely used in industrial and urban drainage, high-rise building pressurized water, fire water supply, air conditioning systems and agricultural irrigation and other purposes. The main transport medium for sucking diluted, clean, non-corrosive water and viscosity below 5 ° E, the physical and chemical properties similar to liquid water without solid particles or fibers. Performance range speed 2900r / min flow 7.5-12m / h 3 power lift 18.5-127m working conditions 1.5-37kW maximum working temperature: 80 ℃. Pump uses direct-type structure, the pump is directly driven by the electric motor, reducing the number of spare parts. Vortex chamber, inlet and outlet flange flange cast a whole. By hydraulic and dynamic balance of the impeller, cantilever-mounted, with high water absorption and high efficiency, strong anti-corrosion ability steam. Using high-quality mechanical seal, so that the pump has a simple structure, reliable performance, small size, light weight, low noise, anti-cavitation performance, low power consumption, easy maintenance features. Model significance Description Direct single-stage centrifugal pump suction pump discharge diameter 100mm diameter 160mm with 80mm nominal diameter of the impeller type impeller diameter first cut of the same type impeller diameter second cutting structure points Ⅰ or Ⅱ configured motors equipped with Y totally enclosed fan-cooled squirrel-cage motor direct-coupled horizontal. Intelligent light alarm function with variable motor with a variable temperature control light technology, according to the motor running temperature, lights junction box cover on the transformation of different colors, in real-time to show the motor running. Two different modes of mounting structure, the structure Ⅰ pump disposed on the cast iron plate. Ⅱ type structure does not require mounting plate, the motor can be directly mounted on a horizontal base. · Pump rotation direction starting from the drive end to the pump should be clockwise direction; · should determine the direction of rotation of the motor is correct, turn the pump before the pump is flexible operation. · Close the gate valve discharge line thereof; · the pump filled with water, or water with a vacuum pump; * power, when the pump reaches normal operating speed, and then gradually opens the valve discharge pipeline, and adjusted to the desired conditions . In the discharge piping of the valve closed, the pump continuous working time must not exceed 3 minutes. Stop · gradually closed valve discharge piping of boil, turn off the power; ? If the ambient temperature is below 0 ℃, the water should be released from the pump to avoid freezing pump; * as long to stop using oil pump should be demolished, Packaging custody. · In the car running and operation of the process, we must observe the meter reading, bearing fever, seal leakage and heat and vibration and noise, such as is normal, if unusual circumstances, should be processed immediately; · bearing temperature not higher than the maximum 80 ℃, bearing temperature must not exceed the ambient temperature 40 ℃; · as part of the seal ring and impeller with excessive wear should be replaced with a new seal. ? Do not machine dry Precautions turn, to avoid damage to the seal; · bearings should be checked regularly; · pump tubing should have its own stand, plus the weight of the pipe is not allowed on the pump, the pump to avoid the crush; · water pipe Each pump must be installed separately, and as short as possible, less bends; · pump manufacture different materials, different pressure, working pressure and the pump pressure must adapt; when transporting non-water class media, please provide physical media, the chemical nature of the consultation with the supplier to determine the applicability of the selected pump, including pump and seal materials; · pump unit wiring and circuit between the power supply for maintenance must be carried out by qualified personnel.
