DESCRIPTION

The 2SK series two-stage liquid ring vacuum pumps are designed to perform efficiently in various industrial applications. These pumps are an advanced version of the SK series water ring vacuum pumps and were developed in the 1980s to meet the demand for higher vacuum levels and greater pumping speed under high vacuum conditions. Unlike the SK series, which can only achieve a maximum vacuum of -700 mmHg, the 2SK series offers improved performance, making it suitable for more demanding environments.

ADVANTAGE

1. Offers higher vacuum and pumping speed compared to traditional SK water ring vacuum pumps.
2. Simple design and easy to maintain, reducing downtime and operational costs.
3. Uses water as the primary working medium, which is cost-effective and environmentally friendly.
4. Suitable for a wide range of applications, including handling water vapor, flammable, explosive, and gases containing small amounts of dust and liquid.
5. Capable of operating in harsh conditions, ensuring reliable performance over time.
 

FEATURES

1. The SK and 2SK series water ring vacuum pumps are versatile and can handle 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 manage corrosive gases effectively.
 
2. The 2YK series liquid ring vacuum pumps provide even higher vacuum levels and better adaptability. By selecting appropriate working media, they can be used for a broader range of gas types, making them ideal for diverse industrial applications.
 
3. These pumps operate smoothly with low noise and energy consumption. They are 30% more energy-efficient than water jet and water vapor jet pumps, offering significant cost savings in long-term operation.

APPLICATION
These pumps are widely used in industries such as chemical, pharmaceutical, metallurgy, food, medicine, textile, papermaking, and electronics. They are suitable for processes like vacuum drying, degassing, concentration, evaporation, and impregnation. When combined with Roots vacuum pumps and atmospheric jet pumps, they can create efficient vacuum systems that achieve high vacuum levels while minimizing 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 inlet pressure 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 inlet pressure 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 inlet pressure 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 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, low-saturated 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. Under special circumstances, if 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, and a gas-liquid separator at the outlet. A mechanical seal should be used for dynamic sealing of the shaft.

3. Choose the dynamic seal of the shaft:
Use packing seals in general occasions; use mechanical seals when the pump is used in non-leakage 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 through which the gas passes 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 of the pump outlet exceeds 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 motor's power should be increased significantly, and special gas-liquid separators and automatic drainage units should be equipped.
When the outlet pressure is below 0.15MPa, the vacuum pump can be refitted as a compressor. The motor's 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 does not need to be circulated or partially circulated.
The closed circulation system should be used if the working liquid in the outlet must be circulated.

Vacuum-formed plastic is used to produce a variety of custom design parts.Vacuum forming become to be a popular and cost-effective solution for a wide range of plastic forming needs.


The product's application must be taken into consideration while selecting the material. Normal vacuum forming plastic included:Polyester, HDPE, LDPE, PVC,PETG,polypropylene, polystyrene, ABS, acrylics, polycarbonate, ASA as well as other ABS capped acrylic and ABS capped polycarbonate.


ABS plastic also named Acrylonitrile Butadiene Styrene,is the most widely used in vacuum forming and available in a range of textured, smooth and embossed finishes, offered in virgin, recycled,UV resistant and flame retardant grades(UL94-V0). As good impact resistance ABS usually is vacuum formed for vehicle,equipment,plastic tray and so on industrial.


HIPS plastic also named High Impact Polystyrene ,is most used in Point of Sale (POS), display and signage market due to its visual appearance (colour options, gloss level, texture), the ease with which it can be processed along with its antistatic and electrical conductivity.


HDPE plastic also named High-Density Polyethylene,is widely used in indoor and outdoor applications including bottles, playground equipment packaging and furniture. It is a plastic with high tensile strength, and good chemical and corrosion resistance.And it has properties of recycling,UV stabilised, improved impact resistance.


PP Plastic also named Polypropylene,is similar to PE. But PE is more harder more heat resistant.But PP is more durable.Mostly plastic tray is produced by PP plastic.


PMMA plastic also named acrylic or glass fiber.It has properties of tensile strength, transparency, polishability and UV tolerance but less impact strength.It is available in clear, antiglare, opal, white, and frosted.It is best choice for windows, displays or see-through enclosures.


PETG named Polyethylene Terephthalate Glycol is another clear rigid plastic sheet.PETG is easily vacuum formed, printed, bonded and polished. As its' excellent clarity and impact resistance, it is widely used in outdoor application.


PC named polycarbonate, has combined advantage of PMMA and ABS. Usually is transparency and semi- transparency. It is expensive but that is best choice for clear plastic vacuum forming.



ASA is one new material which has all good properties of ABS. But much good UV resistant for outdoor usage. It usually be used for radome,air conditioning housing etc outdoor products.



Meanwhile, ABS capped acylic combined the good properties of ABS and acylic. ABS capped polycarbonate combined the good properties of ABS and polycarbonate.If you need high glossy surface for your design,then this is your only choice.
