--- **SK Series Water Ring Vacuum Pump – Overview and Applications** The SK series water ring vacuum pump is designed for the efficient pumping or compression of non-corrosive, water-insoluble, and solid-free gases in a closed system. It can also handle small amounts of liquid mixed with the gas. These pumps are widely used across industries such as machinery, petrochemicals, pharmaceuticals, ceramics, sugar processing, printing, metallurgy, and electronics. Due to the isothermal compression process, they are particularly suitable for handling flammable or explosive gases, reducing the risk of combustion. **Working Principle of the SK Series Water Ring Vacuum Pump** As shown in the diagram, the impeller is eccentrically mounted within the pump casing. When it rotates, centrifugal force causes the water to form a rotating water ring on the inner wall of the casing. During the first half of the rotation, the space between the impeller blades expands, creating a vacuum that draws in gas. In the second half, the space contracts, increasing the pressure and expelling the gas through the exhaust port. This cycle repeats continuously, enabling the pump to maintain a steady vacuum or pressure. During operation, heat is generated, which raises the temperature of the working water. To maintain efficiency, continuous water supply is required to cool and replenish the water lost during the process. If the gas being discharged is not reused, a gas-water separator is connected to the exhaust port. This allows for the separation of gas and water, with the gas being released and the water returned to the pump for reuse. Cold water may be added periodically to maintain optimal working conditions. **Key Components and Structure** The SK series pump consists of a pump body, two end caps, an impeller, and a shaft. The intake and exhaust ports are connected via holes on the end cover discs. The impeller is fixed to the shaft using a flat key, while the clearance at both ends is adjusted using shims. The gap between the impeller and the end cover is managed by bushings or back caps, depending on the model. For larger models like SK-42, the impeller is fitted with an interference fit to ensure stability. The pump uses packing seals or mechanical seals to prevent leakage, with cooling water supplied through dedicated pipes. The bearing is secured using nuts, and the mechanical seal replaces traditional packing in some configurations. **Performance Specifications (Table)** | Model | Gas Flow (m³/min) | Power (kW) | Max.

Finned Tubes

A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.

Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.

The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
