Closed cooling device

LSF type pure water air cooling system


LSF type pure water air cooling system is mainly used in high voltage and UHVDC transmission system (HVDC), flexible AC transmission system (FACTS), high voltage frequency converter, water-cooled motor, high voltage and large capacity static reactive power compensation system (SVG), high voltage and large capacity dynamic reactive power compensation system (SVC), high voltage and large capacity controllable series compensation reactive power compensation system (TSC), ice melting device, high power rectifier, etc, the function of the pure water air cooling system is to take away the heat generated by the power loss of the thyristor devices in the SVC, SVG, TCSC and other devices through the flow of the cooling medium. In view of the heating problem of large power system, LSF pure water air cooling system solves the heat dissipation problem of these cooled systems, greatly improves the stability and reliability of the system, solves the problems of electric corrosion, scaling and blockage of cooling water channel in the application of common water cooling system before, and is suitable for the requirements of energy saving, water saving and energy saving and environmental protection in areas with lower ambient temperature or water shortage.

LSS type pure water cooling system


LSS pure water cooling equipment is mainly used in high-power rectifier power supply, medium frequency furnace power supply, high frequency power supply, water-cooled induction furnace, high-power medium voltage frequency conversion equipment, etc., is the above-mentioned power electronics technology applications are more widely used in the economic type of pure water cooling system. The pure water cooling system solves the heat dissipation problems of these cooled systems, and also solves the problems of electric corrosion, scaling, and blockage of the cooling water channel in the previous ordinary water cooling system applications, and can also meet the compactness, simplicity, and high Reliability and energy saving and environmental protection requirements. Equipped with a reliable closed circulating pure water cooling system, the cooling water temperature, flow, water quality and other indicators control, to achieve system control and protection and communication functions, is the basis for the stable operation of power electronic equipment.

LYF type oil and air cooling system


With the continuous development of human society, the demand for energy is increasing. With the continuous development of the power industry, the capacity of a single transformer is getting larger and larger. At present, 1500MVA single-phase UHV transformers can be produced, and effective heat dissipation is the basis for ensuring the stable and reliable operation of high-power transformers. At present, the application field of transformer puts forward higher requirements for cooling technology, because the forced oil circulation air cooling device has good heat dissipation efficiency, good energy saving and environmental protection characteristics, low noise and other performance, so it has gradually become one of the mainstream in the transformer industry. The LYF oil-air cooling device is mainly used in power transformers, electric furnace transformers, rectifier transformers, etc., and is a cooling system widely used in the above-mentioned transformers. The cooling system solves the heat dissipation problem of these high-power transformers, especially in areas where water resources are scarce, and has the characteristics of water saving, low noise, compactness, simplicity, high reliability, energy saving and environmental protection.

LYS oil-water cooling system


The LYS oil-water cooling device is mainly used in power transformers, electric furnace transformers, rectifier transformers, etc., and is a widely used cooling system for the above transformers. The cooling system solves the heat dissipation problem of these high-power transformers, especially when applied to higher ambient temperatures, and effective heat dissipation ensures the basis for stable and reliable operation of high-power transformers. At present, the application field of transformer puts forward higher requirements for cooling technology, because the forced oil circulating water cooling device has good heat dissipation efficiency, good energy saving and environmental protection characteristics, low noise and other performance, so it has gradually become one of the mainstream in the transformer industry.

Constant pressure variable frequency water supply system


The constant pressure frequency conversion water supply system takes the water pressure of the pipe network (or the user's water flow rate) as the setting parameter, and automatically adjusts the rotation speed of the water pump motor by controlling the output frequency of the frequency converter through the microcomputer, thus realizing the closed-loop adjustment (PID) of the water pressure of the pipe network, so that the water supply system automatically and stably at the set pressure value: that is, when the water consumption increases, the frequency increases, the pump speed increases, the pump speed increases and the pump speed decreases, the water supply is also reduced accordingly, thus ensuring the water supply efficiency of the user's requirements for water pressure and water quantity, and at the same time achieving the purpose of improving the quality and efficiency of water supply, "how much water is used, how much water is supplied"; the use of this equipment does not require the construction of high-level water tanks, water towers, and no secondary pollution of water quality. It is an ideal modern building water supply equipment.

Composition and principle of tubular cooler

The first type of hydraulic machine cooler tube, there are double tube, vertical, horizontal, floating head and so on. The characteristic of this type is that the water used for cooling flows through the inside of the tube, while the oil flows through the interval of the tube. The folded plate in the middle allows the oil to flow, and the two-way or even four-way flow mode it uses makes its cooling effect more intense.

CHARACTERISTICS AND MAINTENANCE FOR COOLER

A cooler is a heat exchange device, mainly used to cool a fluid. They usually use water or air as a coolant to remove heat. There are many types of coolers, including wall type, spray type, jacket type, snake tube type, tube type, corrugated plate type, air cooling type and refrigeration type, etc. Various types of coolers are suitable for different occasions and needs. The common characteristics of coolers are efficient heat transfer capacity, rapid cooling, compact structure, small footprint, long service life, simple maintenance and a wide range of applications.

Advantages and disadvantages of various cooling towers

Counter-flow energy-saving cooling tower refers to the water flow in the tower vertical down, the direction of air flow and the direction of the opposite cooling tower. Counterflow cooling tower is the water in the tower packing, the water in the tower from top to bottom, and the air in the tower flows back from bottom to top, which is both a counterflow cooling tower.
