for large volume allows the pressure drop should use low resistance of the small form factor, whereas resistance selection form.
6. depending on the fluid pressure and temperature selection-detachable or welding.
7. the plates of the selection board area should not be too small, so as to avoid having too many relatively small velocity, reduce the heat transfer coefficient.
8. not to steam plate heat exchanger of heat medium.
6, construction, installation
1. There should be no deformation of heat exchanger, there should be no loose fasteners or other mechanical damage.
2. when hoisting, lifting ropes shall not be hung on to take over, position on the beam or plate.
3. set aside sufficient space around the heat exchanger for easy maintenance.
4. hot and cold media import and export takes over installation, should follow the direction connection factory under the nameplate.
5. connection of heat exchanger tube cleaning should be carried out to prevent sand and welding slag and other debris into the heat exchanger, causing jams.
6. heat exchanger should be 1.5 times the maximum working pressure of hydraulic test, steam steam steam supply pressure parts shall not be less than 0.3MPa, and hot water should not be less than 0.4MPa.
In world economic recession of situation Xia, many China enterprise in for mass of transformation, from traditional market development transformation to Internet network development, in comparison single B2B platform in the select more of promotion way, many jaw crusher and grinding-mill manufacturers enterprise in industry competition very fierce of situation Xia, select has more platform and more website of promotion mode to for promotion publicity, made has very good of effect.
Printing industry is the same, some string tag and hang tag under the situation of dealers in the global market is in the doldrums, more precise market targeting, such as in the United States jewelry cards and the price tag the market is very good, but also to the survival of many foreign trade companies and many opportunities.
But the wedding dresses are not the same, traditional wedding there is no brand leading product promotion manufacturing is very difficult, but some of the big brand companies wedding dress market is very good, such as: wedding dress Anjolique,wedding dress of Bonny which brands are selling very well.
However these industries so fierce competition in the market, there is a market still very stable, it is the tattoo machines , many tattoo supply are wondering why their market is not affected by the global economic shocks

Isolation systems, discharge of water to clean and heat exchangers.
2. Using high pressure water cleaning after retention of silt, algae and other impurities in the pipe, the closed system.
3. Isolation valves and switches between installed ball valve (less than 1 inch = 2.54 cm), water intake and water should be installed.
4. Connected to the pumps and connecting duct, cleaning agent from the pump at the bottom of the heat exchanger, outflow from the top.
5. Begin to pump into the need to heat exchanger fu****aike cleaning agent (the ratio can be adjusted according to the specific situation).
6. Repetition cleaning to the recommended cleaning time. As the cycle progress and dissolving of deposits, produce of gas will increase response time, excess air through the valve discharge at any time.With the discharge of air, space increases in the heat exchanger, can be added to appropriate water, do not inject large quantities of water from the outset, could result in the overflow of water.
