The beneficial effects of the utility model
1, reduces the maintenance cost of down-hole, reduce the supply channel wearing and tearing, prolong the supply channel life-span supply channel
Maintenance cost is by 4 man-hours of every day, each man-hour=72 yuan; Maintenance cost was about 8640 yuan in every month, annual maintenance cost=103680 yuan; Pipeline wearing and tearing aspect had 60 meters water pipes be replaced by corrosion in every month approximately, the direct cost of every meter water pipe=73.5 yuan.The pipeline expense that was replaced in every month is about 73.5*60=4410 unit.Be about 52924 yuan in 1 year; R rates quoted above is as being listed in direct cost, can get annual direct cost to be: 52924+103680=156604 unit.As using water intaking filter under this coal mine, pipeline will extend to original more than 3 times application life.Through measuring and calculating, general expenses is original 1/3, is about 52207.3 yuan, and reducing expenses every year is 104403 yuan; In addition, indirect expense is not also interior.
2, simple in structure, manufacturing and easy to use
Water intaking filter under this coal mine contains closure casing, filtration, and relevant delivery port, water inlet, slag notch, and on the component, and syndeton is simple, very is convenient to make and use.
3, can protect watering equipment
Water after water intaking filter under this coal mine filters, water quality is better, and gravel content is less, can effectively reduce the wearing and tearing that watering equipment causes because of sandstone.
