3NB75 / 2-4 Mine rig mud pump mud pump (3NB4.5 / 2-4 coal slurry pump) drilling rig mud pump mud pump mud pump NB 3NB75 / 2-4 mud pump for most families, the heating costs are not a pens spending. Take 3NB75 / 2-4 mud pump Hohhot, in 2008, due to rising coal prices, the price of heating costs also followed raised from 2.95 yuan per square meter per month 3.68 yuan, a 13NB75 / 2-4 mud pump 20 m2 The house, a moonlight heating necessary expenses 400 yuan. Now coal prices fell, heating costs can be reduced up to easy to difficult, truly puzzling? Explain 3NB75 / 2-4 mud pump interested parties, may sound unreasonable. Hohhot Economic and Social Development Research Center of the NDRC official said: "For a long time, the major 3NB75 / 2-4 mud pump heating companies are at a loss, the loss of some enterprises have relied on government subsidies to reveal all the details." The data provided by the center show, in 2008 to develop the actual heating prices are still lower than the heating costs, when coal prices fell, utilities, labor costs but also in the 3NB75 / 2-4 up mud pump, heating costs per unit area has been higher than for Hot price. The person in charge of the mean, heating costs and heating prices have been upside down, if not declining coal prices, inversion phenomenon will be more serious. Our company specializes in producing all kinds of coal injection pump, injection pump, mud pump mine pumps, submersible sewage pumps. Before 3NB75 / 2-4 mud pump using Profile 3NB4.5 / 2-4 turn coal slurry pump, check the inlet, outlet obstructions, front and rear bearings are butter filling, check the packing is full. Work should be equipped with high-pressure mud pump water pump, mud pump pressure will be greater than the output of water to leak filler, filler for protection, while not close flush pump mud pump work, otherwise, will make part of the rapid wear of the seal. The gap between the impeller and the guard is reasonable, a great impact on the mud pump life.
