How to correctly calculate the cost of the input pump

Many people in the purchase of the pump will be more than three goods, the exact calculation of the pump price, and then choose to meet their own requirements of the lower prices of products. This approach really saves the initial procurement costs, and most of the product in the beginning phase can basically meet the needs of the use. But for users, up to pump in the process of using the effect is far higher than the original purchase and the cost of it, so we must work time will pump problems and failure and maintenance costs are also calculated to overall cost; similarly, pumps in operation will consume a large amount of electricity. A little Months and years pass by. down, the pump power consumption is so staggering.

After some foreign manufacturers of products sold pump tracking survey shows that purchasing cost pump in its life in the largest capital is not the first time, nor the maintenance cost, but the consumption of electrical energy. The following figure shows the results of the analysis of the cost of a foreign manufacturer to pump products.

From this result we were surprised to discover that the original pump power consumption value is far more than the cost of procurement of its own and maintenance costs, and considering the efficiency, noise, artificial maintenance and other reasons of its own, we have what reason to buy the second lowest quality "smuggled goods" products?

In fact, the principle of certain type of pump are the same, the structure, components inside is similar, the biggest difference in material, workmanship and quality components. And other products are not the same, the difference is very significant difference in the cost of the pump, the gap between the average person can not imagine. For example, a small seal, a few cents can buy cheap and good products, but dozens or even hundreds of yuan, as can be imagined by these two kinds of products manufactured products gap is much, but worrying is that in the early stage in the process of using them is almost no difference. Hundreds of thousands of times the price gap is reflected in the performance of the product and the use of the period. The short-lived (months), noise (one or two months), leakage (two or three months) and other phenomena occur continuously, so many users began to regret not the province of the dozens of pieces of money. And the use of the process of high noise and high heat is actually a valuable electric energy conversion in order to have no use of the kinetic energy (mechanical friction) and heat, the actual effective work (pumping) is much less.
