Steel pollution racks, coarse grids, power station pollution racks, reservoir pollution racks

Contact person: Manager Li. A waste rack is composed of a frame, a transverse partition and a grid (see picture). It is supported on a concrete pier wall and is generally made of steel. The spacing between the grids depends on the size, amount and application requirements of the dirt. Hydropower station The spacing between the bars depends on the model and size of the turbine, so as to ensure that the dirt passing through the trash rack will not get stuck in the flow-passing parts of the turbine. Drainage tunnels and drain holes generally do not have trash racks, such as Or if the aperture is not large and there are many sunken wood that need to be installed, the spacing between the bars should be increased. The load on the trash rack, in addition to its own weight, is mainly the water load caused by the water level difference between the front and rear of the rack after the dirt is blocked. Generally, it is considered based on the water head. The size of the grate surface of the trash rack is determined by the flow rate and the allowed flow rate. In order to reduce the head loss and facilitate cleaning, it is generally required that the flow rate across the rack is not greater than about ./. The trash rack can be made into Fixed or capable of being lifted.
