Chemical Industry Vacuum Heat Treatment Water Ring Pump
A pressure vessel is a vessel that can withstand high pressures and is commonly used for storing, transporting, and processing various gases, liquids, and gaseous liquid mixtures. The pressure vessel is mainly composed of vessel body, flange, seal, support and accessories. Common pressure vessels are gas cylinder, gas storage tank, distillation tower, reactor and so on.
The design and manufacture of pressure vessels must comply with relevant national standards and specifications, and pass strict inspection and testing to ensure their safety and reliability. During use, you must comply with the operation regulations and safety precautions, and periodically check and maintain the device to ensure its normal operation and safe use.
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.

ADVANTAGE
1. Compared with the SK water vacuum pump, it offers higher vacuum and better pumping speed.
2. Simple structure and easy maintenance.
3. The primary working medium is water, which leads to low maintenance costs.
4. Widely used across multiple industries, suitable for suction of water vapor, flammable, explosive gases, and gases containing small amounts of dust and liquid.
5. Operates effectively in harsh environments.
FEATURES
1. The SK and 2SK series water ring vacuum pumps are suitable for exhausting both ordinary gases and condensable gases (such as water vapor). Their isothermal compression feature allows safe handling of flammable and explosive gases. When made from anti-corrosion materials, they can also handle corrosive gases.
2. The 2YK series liquid ring vacuum pumps offer even higher vacuum and broader 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 are 30% more energy-efficient compared to water jet and water vapor jet pumps.

Regular Selection for Water/Liquid Ring Vacuum Pump
1. Based on the vacuum value:
(1) If the pump operates for a long time with an 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 operates for a long time with an 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 operates for a long time with an inlet pressure range between 1×10³~1.3×10ⴠPa (between 8 and 100 Torr), choose the 2YK 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 properties; 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 supply water temperature should be below or equal to 15°C; the highest should not exceed 40°C. When using transformer oil or other low viscosity and low vapor pressure industrial oils, the general supply temperature should not exceed 40°C, and the working medium temperature inside the pump chamber should not exceed 60°C. For special cases where a liquid with a lower boiling point is chosen, a cooling unit must be equipped to ensure the maximum temperature is between 30°C and 50°C, below the boiling point. For closed circulation systems, a liquid storage unit and cooler must be installed, along with a gas-liquid separator 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 non-leak situations.
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 passes through 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. Motor selection based on pumping pressure:
If the pump is used for vacuuming while transferring gas, the pump outlet pressure exceeds standard atmospheric pressure.
When the outlet pressure exceeds 0.15MPa, a special double-stage liquid ring compressor should be chosen instead of a refitted vacuum pump. The motor power should be significantly increased, and a special gas-liquid separator and auto-drain unit should be added.
When the outlet pressure is below 0.15MPa, the vacuum pump can be refitted as a compressor. The motor power 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 does not need to be circulated or only partially circulated.
A closed circulation system should be used if the working liquid in the outlet must be circulated.
