Send InquiryIntroduction
Coarse screening is a kind of equipment that uses mechanical method to pull the dirt left by the coarse screening out of the water. For mechanical equipment, it is inevitable that various conditions occur during the operation process, which will directly affect the normal operation of the equipment. Therefore, users need to know the possible causes and solutions of various conditions in advance, so as to solve the fault in time The coarse screening cleaner should be put into operation as early as possible.
There will be various problems in the coarse screening work, and the emission reduction is one of them. If the user encounters the problem of emission reduction in the use process, he can first consider whether the shell and impeller ring are worn. If there is wear, it may cause the above situation. At this time, the pump body and impeller ring need to be inspected, and if there is a problem, it needs to be replaced or repaired in time.

Technical Data
Equipment Characteristics
1. To select the number of decontamination machines according to the width of the ditch
If the working width of single coarse screening is less than 3m, more than three sets can be used. If there are more than three, the cost will be greatly increased. If the width of the ditch is more than 10 m, the mobile decontamination machine should be used, so the economic cost is not high and the decontamination capacity is also available.
2. Choose the style of coarse screening according to the depth of ditch
When the width of the ditch is more than 7m, the wire rope type dirt remover should be used. When the depth is less than 2m, the arc coarse screening dirt remover and the automatic solid-liquid screening machine should be used. The width is 2-7m, that is to say, the chain type dirt remover should be used for the medium depth.
3. Select the appropriate model according to the nature of the pump station and the amount of sewage
According to the size of the dirt, the coarse screening can be set with coarse coarse screening and fine coarse screening. In the water intake pump station and rainwater pump station of the river, it is suitable for coarse and medium coarse screening decontamination. In the sewage pump station, a decontamination machine suitable for medium coarse screening is used. In the inlet pump room of the sewage treatment plant, a decontamination machine suitable for medium and fine coarse screenings is used. If there is a large amount of dirt, a large grab with a large volume or multiple buckets of dirt remover shall be used.
4. Different nature of sewage, choose different material coarse screening.
According to the difference of pH value of sewage, select the corrosion-resistant coarse screening decontamination machine, including 304 and 201 and carbon steel and stainless steel, and use appropriate equipment according to the sewage situation in different places.
