Q:What are the factors affecting heat transfer rate of the chemical equipment

Cold and hot medium temperature, cold and hot medium heat transfer,

Q:What is the working principle of heat pipe

Heat pipe heat transfer element, this can be single use, can also be combined, according to customer's site conditions, with corresponding circulation structure assembled into various forms of heat exchanger, heat pipe heat exchanger has high heat transfer efficiency, small resistance loss, compact structure, reliable operation and maintenance costs less, and other advantages, it is in space technology, electronics, metallurgy, power, petroleum, chemical industry and other industries widely used.

Q:The working principle of new special viscous material scatter equipment?

After drying of material in drum terminal via the discharger discharge finished product, by avoiding the output belt discharging machine, complete the drying process. The dry degree after the product after cooling, drying and color uniform, is ideal.

Q:What iscalled cooler closed?Is used in cooling water temperature and adding vacuum pump work in the refrigeration system

1 sets of rod baffle heat exchanger since 1970 was invented by Philip oil companies in the United States, has been widely used in industrial equipment. In this paper, summarizes the rod baffle heat exchanger system of regenerative heat exchanger in the heat power plant of the two application examples, the experience for reference and reference.

Q:How to wash hot water exchanger heat

The simplest is to use clean with weak acid, vinegar, take in and out of the gate with a metal hose, poured the vinegar in a period of time, in the repeated washing. A lot of heat exchanger cleaning methods 1, join in the heat exchanger cleaning liquid circulation, can take some dirt. 2, flush with water cannon directly. 3, the most radical approach is removed all clean.

Q:What is heat transfer, heat transfer is wha

Heat conduction is no macroscopic movement at the time of the heat transfer phenomena in the medium, its all can happen in solid, liquid and gas, but strictly speaking, only is the pure heat conduction in solids, and fluid even in static state, which will be due to the temperature gradient caused by the natural convection resulting from the density difference, therefore, the heat convection and heat transfer in the fluid at the same time.

Q:Should be prepared to what kind of equipment and materials and tools and equipment?

The role of the tube plate is heating tube bundle and the tube side and shell side fluid separation. You can keep the swelling down Tube plate and pipe connection or welding. Inflation connection is the use of expansion tube bulge, a significant plastic deformation, to achieve the purpose of sealing fastening between tube and tube plate according to the pressure. Expanding joint method is usually used segment of the carbon steel pipe carbon steel or low alloy steel, the design of less than 4 million mpa pressure, design temperature does not exceed 350 °. It is shell (3) of the head and tube box Head and tube box located at both ends, it is the function of control and distribution of tube side fluid.

Q:Why heater before operation will be into the air in the device?

The first, air expansion coefficient is big, the residual air is heated in the airtight container is in danger of explosion overpressure. Second, low thermal conductivity, air pipes in air part of can not get effective cooling during heating, may cause damage of partial wall overtemperature. Third, in line with air may form the "water hammer", a strong shock.

Q:how to prevent

Boiled eggs in addition to scale Boiling water on the pot, use for a long time scale hard and hard. If use it twice boiled egg, can get ideal result.

Q:Refrigeration equipment of the evaporator

Evaporator is also called heat absorber, which is by the boiling vaporization of liquid refrigerant load cooling or cooling heat transfer device object to be cooled. Evaporator can be divided into two kinds: one kind is the cooling liquid type, used for cooling liquid refrigerant, tube shell type evaporator and flooded evaporator (such as vertical pipe, spiral pipe, coil type).
