What's bridge filter
Bridge filter is a kind of bridge-shaped water filtration equipment. It has long been widely used in developed countries. Engaged in hydrogeological exploration, drilling, drilling construction, reservoir precipitation, basic deep dig precipitation, geothermal development and utilization, development and utilization of mineral water, geothermal air conditioning, bad hole repair, groundwater sources such as water. In the 1980s, the Ministry of Geology and Mines began to introduce and popularize with satisfactory results and was hailed as the ideal water filter.
Performance
1, a bridge with a hole in the drainage pipe, known as the ideal water filter.
2, has a higher water filtration capacity of the water. Wash well in addition gravel to obtain more efficient water.
3, special bridge filter structure, enhanced tube strength, with high mechanical strength.
4, bridge filter coated (coated) galvanized coating, improve the service life of wells.
5, Bridge-type drainage pipe using steel punching, rolling, light weight, low price.
6, a variety of connections, under the tube easy to operate, suitable for field production
Technical Advantage
1. The special structure of the bridge hole makes the gravel difficult to block the hole.
According to the German Noord company test, the traditional water filter gravel porosity to be reduced by 40%, while the bridge filter only Decline of 10%.
Therefore, the bridge water filter has a high water capacity.
After the wells were washed wells get sand clean water after cleaning.
2. The special pore structure of the water filter has the effect of enhancing the mechanical strength of the water filter. It has high mechanical strength.
3. According to user needs, plating (coating) has a different coating, can improve the service life of wells.
4. Bridge water filter system using steel punching, rolling made, so light weight, cheap.
5. Can use a variety of connections, so under the tube easy to operate.
6. According to user requirements, change the gap of its bridge hole, so that users get a satisfactory bridge porosity.
7. According to user requirements, to provide any diameter bridge filter, greatly facilitate the user.
Applications
Used in hydrogeological exploration, drilling, geological precipitation, geothermal utilization, mineral development, mining, petrochemical and other fields.
