Water pumps, generators and other products will see market development
With the advent of summer and the intensification of the contradiction between supply and demand of kerosene, the supply of electricity across the country is once again tense, thus driving the hot sale of pumps and generators in the second phase market. According to relevant information, in the second half of the year, there is still a large gap after the balance of electricity in China. In order to ensure production, life water. Electricity demand, at present, many units in various provinces and cities in China. Hotels and restaurants. Residential communities have to buy pumps, generators, many enterprises in order not to delay the production, but also out of their own pockets to prepare the generator. In this promotion, water pumps and generators have naturally become a commodity in demand. According to another analysis, at least in recent years, the situation of power shortage will continue, and the growth trend of China's economy will still maintain high growth, so the contradiction between power supply and demand in recent years is still prominent? This is undoubtedly an opportunity for the pump and generator industry.

China Hardware City pump product sales towards polarization
Every year in the summer, the water pump industry in China Science and Technology Hardware City market will usher in the peak sales season. Water pumps, like electric fans and heaters, are basically seasonal products and are particularly popular in summer. However, compared with the latter, the market supply and demand in other seasons tend to be stable. Jin Chunfang, the owner of the wholesale water pump department, who has been engaged in the water pump business in the Jindu market for nearly 7 years, told me: After selling water pumps for many years, I have a deeper understanding of the sales rules and trends of this industry. Generally speaking, each pump seller will have a group of fixed customers, and can receive orders steadily every year. However, want to pump sales heating up, in addition to the requirements of the operator's own continuous efforts and product brand loud, quality is excellent, but also rely on God.

Installed centrifugal pump to determine the height of the pump is the focus
The key to the installation technology of centrifugal pump is to determine the installation height of the pump. This height refers to the vertical distance from the water surface to the center line of the impeller of the pump, which cannot be confused with the allowable vacuum height. The allowable vacuum height indicated on the pump nameplate or product manual refers to the vacuum value on the water inlet section of the pump, and it is measured under 1 standard atmosphere pressure; the water temperature is 20 degrees Celsius, and the test is conducted. It does not take into account the water flow condition after the suction pipeline. The installation height of the pump should be allowed to suck up the vacuum height after deducting the loss of head of the suction pipe, the remaining part of the value, which should overcome the actual terrain suction height. The installation height of water pump cannot exceed the calculated value, otherwise, the pump will not be able to pump water. In addition, the size of the influence of the calculated value is the resistance of the suction pipe loss head, therefore, it is appropriate to use the shortest pipeline arrangement, and as little as possible to install elbows and other accessories, but also consider the appropriate with some large caliber of water pipe, in order to reduce the flow rate in the pipe.

2012 pump industry development strategy research
Water pump motor stealing power, is already an indisputable fact, not to mention the fire motor. So many pumps debugging and installation found over current, motor hot, after checking not the pump head too high selection is not right, and finally returned to the manufacturer, replace the motor well.
