A stable and reliable vacuum is the key to all processes, from distillation to steam recovery.With the variety of technology options available, many industries are looking for dry vacuum technologies to meet stringent environmental regulatory requirements and overcome existing system technology constraints.

 

A controlled vacuum can be applied to a series of processes for the following reasons:

 

Extraction rate: the vacuum can be applied to the main condenser of the power plant to minimize the amount of steam required while maintaining turbine operation.

 

Increased production: refineries vacuum oil towers for proper distillation and recovery at lower temperatures without damaging valuable high molecular weight hydrocarbon chains.

 

Maintain quality: in pharmaceutical processes, vacuum is used not only to initiate reactions but also to help maintain the color and quality of the finished product.

 

Applying a vacuum to any process is an important and often delicate operation.The lack of a stable and reliable vacuum not only adversely affects the production process but also the end product.Therefore, depending on the device and application, a number of different techniques can be used to create a vacuum.

 

 

The types of vacuum pump include: liquid ring vacuum pump, steam jet, hydraulic jet, fuel injection booster, diffusion pump, piston pump, blower, OTO pump, blade pump, dry pump, claw pump, dry screw pump, etc.

 

Vacuum technology includes dry pump, liquid ring pump and compound system, the performance is different.All of these technologies have advantages and disadvantages.These technologies have a common limitation.In the single stage 0.1 support suction pressure, except dry screw pump compression ratio of 7600:1 or higher, other pump compression ratio is limited.

 

To choose the right technology for the production process, engineers need to know and understand the technology and have a deep understanding of the application and process.As with any complex system, it is critical to select and combine each component to achieve and maximize the expected reliability, efficiency, and total cost of ownership (TCO).After the proper pump is selected, the engineer can begin to select the remaining components, such as heat transfer equipment, containers, pipe diameter and orientation, VFDS, instrumentation and control equipment.Each component must be designed and selected in conjunction with the main vacuum generator to achieve good results.

 

 

Due to increasingly stringent environmental regulations, chemical, pharmaceutical and research institutions are turning to the application of dry technology, which is beginning to gain attention in some fields.

 

For example, in distillation, reactor, evaporator, exhaust, drying, filtration, mixing, stripping, freeze drying, sterilization, and laboratory development applications, the composition and conditions of the gas vary from product to product.

 

In addition to compliance with regulations, dry screw pumps offer several functional advantages over competing technologies, namely:

 

· the pressure of the limiting separation is less than 0.1 torus

 

· operating within full pressure range (using single-stage compression)

 

, rate (CFM/BHP)

 

· all wetted parts are coated

 

· cleaner running process without using any liquid

 

· the product has no pollution, no waste generation and no pollutant treatment

 

· the solvent or steam can be condensed in the condenser without contamination

 

· the machine operation capacity can be increased by adding a vacuum booster in front of the dry screw pump

 

· the pump can run continuously under separate conditions.For batch processes, as soon as the next batch of products begins production, a reliable, usable vacuum.
