The clapping door of axial flow pump makes a loud noise, and Jinan TEDA pump industry will deal with it according to the following methods: 1、 The common clap door sound is big, if the rubber ring is excessively worn or lost, replace it with a new one. 2. When the underwater depth of ordinary flap door is deep, the pressure is large and the noise is loud. Change the float box flap door, 3. When the underwater depth of ordinary flap door is deep, the pressure is large and the noise is loud. If you don't want to change the float box flap door, there is a lifting lug on the flap door cover produced by the regular manufacturer. Add a pulley and weight hammer to hang on the flap door cover to reduce the pressure. 4. When the flap door is above the water surface, the flap door will be closed slowly when the machine is stopped, the noise is small, and the large-diameter flap door is heavy, so the pulley type hammer can be added. 5. When the underwater sound of the flap valve of the floating tank is loud, part of the water can be discharged to increase the buoyancy. Someone may say how to drain the water under the water. There is a way. Connect the air hole on the floating tank cover with the air pipe for ventilation and drainage. Open the lower drain hole and adjust it to the appropriate level (stop the air, test, continue the air exhaust, light). Loosen the upper hole, the water will continue to enter the upper modification), remove the air pipe, screw on the screw, OK! |
