How much is the pump for a month?
Depends on you are a big pump, small pump, and now about 0.7 of the fuel consumption, and you do a month how much work, generally, if you do 10000 square a month, then two years to recover costs
Remove the pump car monthly fuel maintenance consumption (about 10 thousand to 5000), calculate the monthly one of the clay, probably earn about 14 to 150 thousand net!
Excluding oil costs, each side of the soil about 0.5 oil (Sany E series pump), the 7000 sides will be about 3500L oil X7.33=3 yuan, remove the wages of workers (4 per person 5000=2 million)
In the mud, the price is about 25 yuan per square, according to my experience, more than 175000 points per month can pump 7000 yuan, totaling $
