Cast iron fountain pump features

Cast fountain pump features:

    1, the use of cast iron or stainless steel, pump to improve the corrosion resistance. 

    2, impeller with special materials to prevent the impeller when the impeller loose.

    3, leakage protection measures: the use of fixed potential grounding device.

    4, on the basis of the original ordinary pump, according to the requirements of the fountain pump, in the continuous development of technology, processing materials on the continuous improvement of the fountain dedicated pump can be frequent start, completely suitable for the use of music fountain. 

    5, the pump with stainless steel filter cover, three-phase four-wire cable. 

    6, stainless steel fountain pump for automatic water injection function. In this case,

    7, the motor is self-circulating water-cooled.

working principle

    Before opening the pump, the suction pipe and pump must be filled with liquid. After the pump is pumped, the impeller rotates at high speed, and the liquid rotates with the blade. Under the action of centrifugal force, it leaves the impeller outward and the liquid is gradually slowed down and the pressure gradually increases from the pump Outlet, discharge pipe out. At this point, at the center of the blade at the center of the liquid is thrown to the surrounding and the formation of both no air and no liquid vacuum low pressure area, liquid pool in the pool of atmospheric pressure under the action of the suction pipe into the pump, the liquid is so continuous Constantly being sucked up from the liquid pool and continuously flowing out of the discharge pipe.

    Turn to the right turn to the right fountain pump unit consists of four parts: pump, submersible motor (including cable), water pipe and control switch. Submersible pump for the single-suction multi-stage vertical centrifugal pump; submersible motor for the closed water wet, vertical three-phase squirrel cage asynchronous motor, motor and pump through the claw or single-button coupling directly; motor materials using high-quality DR470 Cold rolling Xi Gangliao, increase the number of turns of the motor windings and the diameter of the diving line, the cable with three-phase four-wire JHS fountain dedicated cable, impeller increased anti-loose device, the motor cavity using imported anti-rust enamel, The above structural improvements make the submersible pump inertia small, so the response speed, bearing the use of high-performance dedicated shaft, improve the insulation level, so as to meet the frequent needs of the music fountain frequent start.
