WORKING THEORY

The SK and 2SK series water ring vacuum pumps are designed to handle both non-condensable and condensable gases, such as water vapor. These pumps operate with isothermal compression, making them suitable for flammable and explosive environments. When using corrosion-resistant materials, they can also manage corrosive gases effectively.
The 2SK series two-stage liquid ring vacuum pump functions similarly to two SK series units. Due to the limitations of the SK series in achieving high vacuum, the 2SK series was developed in the 1980s to provide higher vacuum and greater pumping speed at high vacuum levels.
The 2YK series liquid ring vacuum pumps offer improved vacuum performance and broader applicability. By selecting appropriate working media, these pumps can handle a wide range of gas types.
These pumps run smoothly with low noise and energy consumption, saving up to 30% compared to water jet and water vapor jet pumps.

APPLICATION

This pump is widely used in processes such as vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, and vacuum impregnation across industries like chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electronics. It can be combined with Roots Vacuum Pumps and atmospheric jet pumps to achieve high vacuum, high efficiency, and low power consumption.

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 1.3×10⁴~1×10⁵ 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 5×10³~1.3×10⁴ Pa (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 1×10³~1.3×10⁴ Pa (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 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 temperature of supply water should be lower than or equal to 15°C; the highest one should not be higher than 40°C. While transformer oil or other low viscosity and saturated vapor pressure industrial oils are used as the working media, the general supply temperature should not exceed 40°C, and the working media temperature inside the pump chamber should not exceed 60°C. When a liquid with a lower boiling point is chosen as the working medium under special circumstances, a cooling unit must be equipped to cool down the working media to ensure that the maximum temperature is between 30°C and 50°C, lower than the boiling point. For a closed circulation system of working media, a liquid storage unit and cooler must be equipped, and a gas-liquid separator must be installed at the outlet. A mechanical seal should be used for the dynamic seal of the shaft.


3. Choose the dynamic seal of the shaft:
Choose packing seal in general occasions; choose mechanical seal when the pump is used in a no-leak occasion.

4. Choose the material of the part that the gas passed:

(1) For the non anti-corrosion pump, the shaft is made of 45# steel or 40Cr, other parts are made of cast iron or brass;
(2) For the anti-corrosion pump, 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 coating.


5. The motor should be selected based on pumping pressure.

If the pump is used for vacuuming while transferring gas, the pressure of the pump outlet exceeds the standard atmosphere pressure.
When the outlet pressure exceeds 0.15MPa, a special double-stage liquid ring compressor should be chosen instead of a vacuum pump. The motor power should be significantly increased, and a special gas-liquid separator and auto-drain unit should be equipped.
When the outlet pressure is below 0.15MPa, the vacuum pump can be used as a compressor. The motor power should be increased appropriately.


6. Composition methods of the water ring vacuum pump system
The open circulation system should be used if the working liquid in the outlet need not be circulated or partially circulated.
The closed circulation system should be used if the working liquid in the outlet must be circulated.

Elastic Warping Machine

The Elastic Warping Machine, also known as spandex warping machine, is a textile machine used to produce elastic fabrics. It is designed to warp a wide range of elastic materials, including spandex, Lycra, and other stretchable fibers.

The machine consists of a creel, a warp beam, a tension control system, and a warping section. The creel holds the spools of elastic yarn, which are then fed into the warping section. The tension control system ensures that the yarn is evenly distributed and maintains a consistent tension throughout the process.

The warping section consists of a series of rollers that pull the yarn through a series of guides and onto the warp beam. The elastic yarn is then wound onto the warp beam, creating a tightly-woven fabric that can stretch and recover without losing its shape.

The Elastic Warping Machine is widely used in the production of a variety of elastic fabrics, including swimwear, athletic wear, lingerie, and medical garments. It is a highly efficient and cost-effective way to produce high-quality elastic fabrics with consistent performance and durability.
