DESCRIPTION
The 2SK Series Two-Stage Liquid Ring Vacuum Pumps are designed to perform efficiently like two SK series water ring vacuum pumps. Due to the limitations of SK series vacuum pumps, which only achieve a maximum vacuum of -700 mmHg, China developed the 2SK series water ring vacuum pump in the 1980s to meet the demand for high vacuum and large pumping speed under such conditions. These pumps are widely used across various industries for their reliability and efficiency.


ADVANTAGE
1. Compared with SK water vacuum pumps, it offers higher vacuum and pumping speed.
2. Simple structure and easy maintenance.
3. Water is the primary working medium, leading to low maintenance costs.
4. Suitable for various environments and can handle water vapor, flammable, explosive gases, and gases with small amounts of dust and liquid.
5. Operates effectively in harsh conditions.

FEATURES
1. The SK and 2SK series water ring vacuum pumps can exhaust both ordinary gases and condensable gases (such as water vapor). Their isothermal compression feature allows them to 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 suitable working media, different types of gases can be pumped, making them applicable in a wider range.

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.

PARAMETER

 
APPLICATIONS
These pumps are ideal for vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, and vacuum impregnation processes in chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electrical industries. They 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) For long-term operation with inlet pressure between 1.3×10⁴~1×10⁵ Pa (100~760 Torr), choose the SK series water ring vacuum pump.
(2) For long-term operation with inlet pressure between 5×10³~1.3×10⁴ Pa (40~100 Torr), choose the 2SK series water ring vacuum pump.
(3) For long-term operation with inlet pressure between 1×10³~1.3×10⁴ Pa (8~100 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
When using water as the working medium, the best supply water temperature should be ≤15°C, and the highest should not exceed 40°C. If transformer oil or other low-viscosity and low-saturated-vapor-pressure industrial oils are used, the general supply temperature should not exceed 40°C, and the working medium temperature inside the pump chamber should not exceed 60°C. In special cases where a liquid with a lower boiling point is selected, a cooling unit must be equipped to ensure the maximum temperature is 30°C–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 a non-leak environment.

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 or 306, or other materials suitable for the respective corrosive gas, or have 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 0.15 MPa, 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 0.15 MPa, the vacuum pump can be refitted as a compressor, with proper motor power increase.

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 is partially circulated. A closed circulation system should be used if the working liquid in the outlet must be circulated.

Clear Vacuum Forming

Clear vacuum forming is a manufacturing process used to create clear plastic products. It involves heating a sheet of clear plastic until it becomes pliable, then placing it over a mold and using a vacuum to force the plastic to conform to the shape of the mold. Once the plastic cools and hardens, it retains the shape of the mold, resulting in a clear Vacuum Forming Plastic products.

This process is commonly used to create packaging materials, such as vacuum forming packaging and clamshell packaging, as well as various consumer products like vacuum forming display cases, vacuum forming light covers, and point-of-purchase displays. The clear plastic allows for easy visibility and showcases the product inside.The normal plastic type is polycarbonate,arcylic or petg plastic.

Clear vacuum forming offers several advantages, including cost-effectiveness, versatility, and the ability to produce complex shapes with intricate details. It is a popular choice for manufacturers looking to create transparent or translucent plastic products.
