Many people buy more pumps than three, accurately calculate the price of the pump, and then choose products that can reach their own requirements. This practice does save the initial cost of the purchase, and most of the products can basically meet the needs of use at the beginning. 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 a follow-up investigation of some products sold abroad, the largest cost of pumps in their service life is not the initial purchase cost, nor the maintenance cost, but the electricity consumption. The following figure shows the results of an analysis on the cost of pump input from a foreign manufacturer.

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 &ldquo smuggled goods; ” products?

In fact, the principle of a certain type of pump is the same. The structure and components of it are very similar. The biggest difference is reflected in the material selection, workmanship and quality of components. Unlike other products, the cost difference between the components of the pump is very significant, and the gap is too large to be imagined by the average person. 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. A hundred thousand times the price gap is reflected in the performance and duration of the product. Short lived (a few months), noise (one or two months later), leakage (two or three months later) and other phenomena continue to happen. Many users regret not starting to save dozens of yuan. The noise and high calorie in use are actually valuable electric energy conversion. For the useless kinetic energy (mechanical friction) and heat energy, the effective work (pumping) actually does little.
