        • Self-priming sewage pump priming how to improve performance

        • time:2014-2-8 17:39:52source:author: click:
        • The following improved self-priming sewage pump self-priming performance in several ways
          The first: self-priming sewage pump suction pipe ends to install suction end of the valve.
          Suction end of the valve is actually a non-return valve, which can only be guaranteed by the pool water into the suction tube and can not turn the

          clock back, so if the water pipe is filled with water, although the axis of elevation above the pool pump working level, but because of suction end

          acting valve, the water will not flow into the suction tube pool, make the suction tube has been filled with water to ensure the pump can

          automatically and quickly started. The reliability of this absorbing way affected the quality of suction end of the valve, for example, closed lax,

          leaks, water suction tube will slowly shed pool, a long time, there is no water in the suction pipe, causing the pump starts when still require

          artificial irrigation.
          Second: reduce self-priming sewage pump inlet pipe bend, drop height and horizontal distance.
          Third: self-priming pump sewage pump set before the suction tank.
          This approach needs to be set on the pump suction pipe of a suction tank, the pump before the first run, the tank should be filled with water

          manually, after the first run stopped because the suction tank inlet pipe height above the water level, although the pool water level is lower than

          the height of the water tank, the tank water will not be back into the pool, so, water tank can store some water, and because the suction tank outlet

          pipe (ie pump suction pipe) Height below the water level inside the tube, it is filled with water to ensure the pump suction pipe, then run after the

          pump, the water inside the tank is pumped pump, the tank appears negative, pools of water under atmospheric pressure added suction tank through the

          suction tank pool
          Fourth: self-priming sewage pump set Vacuum pump suction pipe in the road, before starting the pump, vacuum pump first start, the first pump suction

          tube filled with water, the pump automatically guarantee quick start. This approach requires a sound absorbing automatic control system to ensure the

          normal operation
