Chemical Industry Vacuum Heat Treatment Water Ring Pump
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.

ADVANTAGE
1. Compared with the SK water vacuum pump, it achieves higher vacuum and pumping speed.
2. Simple structure and easy maintenance.
3. The working medium is mostly water, resulting in low maintenance costs.
4. Widely used across various industries, capable of handling water vapor, flammable, explosive, and gases containing small amounts of dust and liquid.
5. Operates effectively in harsh conditions.
FEATURES
1. The SK and 2SK series water ring vacuum pumps can be used for exhausting both ordinary and condensable gases (such as water vapor). Due to their isothermal compression characteristics, they can safely handle flammable and explosive gases. When made from anti-corrosion materials, they can also be used for corrosive gases.
2. The 2YK series liquid ring vacuum pumps offer higher vacuum levels and better applicability. By selecting appropriate working media, different types of gases can be pumped, making them suitable for a wider range of applications.
3. These pumps operate smoothly, with low noise and energy consumption. They save up to 30% energy compared to water jet and steam jet pumps.

Regular Selection for Water/Liquid Ring Vacuum Pump
1. Based on the vacuum value
(1) If the pump is operated for long time with the inlet pressure range between 1.3×10â´~1×10âµ Pa (between 100 and 760 Torr), choose the SK series water ring vacuum pump.
(2) If the pump is operated for long time with the inlet pressure range between 5×10³~1.3×10ⴠPa (between 40 and 100 Torr), choose the 2SK series water ring vacuum pump.
(3) If the pump is operated for long time with the inlet pressure range between 1×10³~1.3×10ⴠPa (between 8 and 100 Torr), choose the 2YK series liquid ring vacuum pump.
2. Working Media
There are four principles to choose working media (i.e., ring liquids):
(1) Lower saturated steam pressure
(2) Lower viscosity
(3) Stable physical and chemical features; no chemical reaction with the pumped gas; no corrosion to the pump; no pollution to the environment.
(4) Economy
If water is selected as the working medium, the best temperature of supply water should be lower than or equal to 15°C; the highest one should not exceed 40°C. For transformer oil or other low viscosity and low vapor pressure industrial oils, the general supply temperature should not exceed 40°C, and the working media temperature inside the pump chamber should not exceed 60°C. Under special circumstances, when a liquid with a lower boiling point is used, a cooling unit must be equipped to cool the working medium to ensure the maximum temperature is between 30°C and 50°C, below the boiling point. For a closed circulation system, a liquid storage unit and cooler must be installed, and a gas-liquid separator must be placed at the outlet. A mechanical seal should be used for the shaft's dynamic seal.
3. Choose the dynamic seal of the shaft:
Use packing seal in general occasions; use mechanical seal when the pump is used in a non-leak situation.
4. Choose the material of the part that the gas passed:
(1) For non-anti-corrosion pumps, the shaft is made of 45# steel or 40Cr, and other parts are made of cast iron or brass.
(2) For anti-corrosion pumps, the parts that the gas passed should be made of stainless steel 304 and 306, or other materials suitable for the respective corrosive gas, or the parts should be coated with anti-corrosion coatings.
5. The motor should be selected based on the pumping pressure.
If the pump is used for vacuuming while transferring gas, the pressure of the pump outlet exceeds the standard atmospheric pressure.
When the outlet pressure exceeds 0.15MPa, a special double-stage liquid ring compressor should be chosen instead of a vacuum pump. The power of the equipped motor should be significantly increased, and a special gas-liquid separator and auto-drain unit should also be equipped.
When the outlet pressure is below 0.15MPa, the vacuum pump can be refitted as a compressor. The power of the equipped motor should be appropriately increased.
6. Composition methods of the water ring vacuum pump system:
An open circulation system should be used if the working liquid in the outlet need not be circulated or partially circulated.
A closed circulation system should be used if the working liquid in the outlet must be circulated.
