The heat exchanger is widely used in the circulating water system for winter heating in family buildings, office buildings, hotels, etc. After use for a period of time and after the end of the pipeline construction without slag flushing, resulting in a large amount of internal scale and welding slag foreign matter, clogging the pipeline, resulting in poor heat exchange effect. Therefore, it must be cleaned regularly to restore its original efficiency.

Leaks occur when they cause a reduction in feedwater pressure and a reduction in the amount of feedwater sent to the boiler. Therefore, the discovery of shell and tube heat exchanger tube system leaks immediately stop the heat exchanger to reduce the number of damaged tubes and reduce the degree of

Any corrosion problem must be investigated through the field, through the daily monitoring and regular testing of equipment, in order to understand the shape of corrosion and grasp the specific circumstances of corrosion, in order to take effective measures to solve it. Heat exchanger unit corrosion investigation can be in the heat exchanger unit shutdown maintenance to take the regular corrosion inspection. Here we introduce some inspection methods and prevention strategies.

Heat exchanger unit comprehensive corrosion control is from the design, manufacturing, storage, transportation and installation, operation and operation, maintenance, and other five aspects of corrosion protection control, so as to reduce corrosion losses to a minimum level.

The refrigeration system with Freon as the refrigerant medium mainly consists of 4 major components, namely compressor, condenser, expansion valve, and evaporator. Condenser and evaporator in function, are different temperature fluid mediums to achieve mutual heat exchange equipment, so collectively referred to as heat exchangers. In the rail vehicle air conditioning industry, the more finned tube heat exchanger is used.

The displacement heat exchanger is a very widely used heat exchanger, which is mainly composed of the body, steam coil assembly, steam import and export, hot and cold water import and export, etc., so how to choose a displacement heat exchanger, today to introduce you to the volumetric heat exchange

The displacement heat exchanger is mainly composed of a controller motor, temperature control device, thermometer, pressure gauge, pressure pump, container, tank, safety control device, shell, piping, etc. It can realize the heat exchange between hot fluid and cold fluid and is a more common heat ex

The displacement heat exchanger is the use of cold and hot fluids alternately flow through the heat storage chamber in the heat storage body (packing) surface so that the heat exchange heat exchanger, the inter-wall displacement heat exchanger cold and hot fluids are separated by a solid inter-wall,

The replacement heat exchanger is designed to increase the heat transfer performance by increasing the flow of hot medium and heated water and changing the laminar heat transfer to turbulent heat transfer. The heat exchange part is completely separated from the heat storage part to achieve the purpo
