DESCRIPTION
The 2SK Series Two-Stage Liquid Ring Vacuum Pumps are designed to perform efficiently like two SK series water ring vacuum pumps. While the SK series pumps can only achieve a maximum vacuum of -700 mmHg, the 2SK series was developed in the 1980s to meet the demand for high vacuum and large pumping speed under such conditions.


ADVANTAGE
1. Compared with SK water vacuum pump, it achieves higher vacuum and pumping speed.
2. Simple structure and easy maintenance.
3. The main working medium is water, resulting in low maintenance costs.
4. The pump is widely used in various areas and can handle water vapor, flammable, explosive, and gases containing small amounts of dust and liquid.
5. It performs well in harsh conditions.

FEATURES
1. The SK and 2SK series water ring vacuum pumps can exhaust both ordinary and condensable gases (such as water vapor). Due to their isothermal compression feature, they can also handle flammable and explosive gases. If made from anti-corrosion materials, they can be used for corrosive gases too.

2. The 2YK series liquid ring vacuum pumps offer higher vacuum and better applicability. Different types of gases can be pumped using suitable working media, 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
This pump is suitable for vacuum drying, vacuum degassing, vacuum concentration, vacuum evaporation, and vacuum impregnation processes in chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electrical industries (including the electronics field). It can be combined with Roots Vacuum Pumps and atmospheric jet pumps to create a vacuum system that achieves 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 a long time with an 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 a long time with an 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 a long time with an 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
When 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. When transformer oil or other low viscosity and low saturated vapor pressure industrial oils are used as the working medium, 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 used as the working medium under special circumstances, a cooling unit must be equipped to cool the working medium to ensure that the maximum temperature is 30°C–50°C, below the boiling point. For closed circulation systems 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:
Use a packing seal in general situations; use a mechanical seal when the pump is used in a non-leakage condition.

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 the parts should be coated with anti-corrosion coatings.

5. The motor should be selected based on pumping pressure.
If the pump is used for vacuuming while transferring gas, the pressure at the pump outlet exceeds the standard atmospheric pressure.
When the outlet pressure exceeds 0.15 MPa, a special double-stage liquid ring compressor should be chosen instead of a refitted vacuum pump. The power of the equipped motor should be significantly increased. Special gas-liquid separators and automatic drainage units should also be equipped.
When the outlet pressure is below 0.15 MPa, the vacuum pump can be refitted as a compressor. The power of the equipped motor should be increased appropriately.

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.

Heat Exchanger

A heat exchanger is a device used to transfer heat, usually to transfer heat from one fluid to another without them mixing. A heat exchanger usually consists of a number of parallel pipes in which one fluid flows through the pipe and another fluid flows through the outside of the pipe. In this way, heat can be transferred from one fluid to another for heating or cooling purposes. Heat exchangers are widely used in many industries, such as chemical, pharmaceutical, food processing, air conditioning and heating systems, etc.

Heat exchanger usually consists of the following components:
1. Heat exchange pipe: Pipe used to transfer heat, usually made of metal materials, such as copper, stainless steel, etc.
2. Heat exchange surface: A surface used to transfer heat, usually consisting of metal sheets or pipes. The greater the surface area, the higher the heat transfer efficiency.
3. Housing: Housing, usually made of metal or plastic, used to secure heat exchange pipes and surfaces.
4. Seals: Seals used to prevent media leakage, usually made of rubber or silicone rubber.
5. Support: A support used to support a heat exchanger, usually made of steel or cast iron.
6. Import and export pipes: pipes used for medium entry and exit, usually made of metal or plastic.
7. Cleaning hole: A hole used to clean the inside of the heat exchanger, usually located on the upper or side of the heat exchanger.
8. Insulation layer: Insulation layer used to keep the temperature of the heat exchanger stable, usually made of glass wool or polyurethane foam.
