The reliability, use effect and service life of the Mechanical Screen equipment have been fully applied, and it is an ideal equipment for cleaning the water inlet of small and medium-sized pumping stations. In the meantime, after many technical improvements, the product structure has gradually improved. Of course, you need to pay more attention when designing the Mechanical Screen.

For example, the material of the grate tube of the Mechanical Screen should have sufficient diameter and wall thickness. Generally, the width of the cleaning machine with a span of less than 6 meters, the gingival tube is checked by the concentrated load of 10000 N.m, and the deflection is not more than 1/250. The wall thickness of the steel pipe should not be less than 6mm. For larger size rotary cleaning machines, it is conceivable to use multiple traction chains to improve the force of the gums, or to make them into variable-section members by local reinforcement of the middle of the gum tube.

The long-pitch plate roller chain is the main moving part of the rotary Mechanical Screen. For the chain arc transition, the diameter should be increased as much as possible to ensure the smooth transition and reduce the pressure on the arc track surface. For a common plate roller chain with a pitch of 125, the transition radius should not be less than 350 mm.www.khnwatertreatment.com
