Pharmaceutical factories mainly use vacuum pumps to do what processes

Pharmaceutical factories use vacuum pumps more in the low-temperature concentration, extraction and drying process of APIs, and according to the saturation vapor pressure value of the material, vacuum equipment with different ultimate vacuum degrees is selected.

Look at what kind of medicine is made, the process is different, and the use is different. I see that there are Chinese medicine extractions. Lyophilized, as well as solvents**. Much more.

Vacuum evaporation, concentration, distillation, crystallization, drying, extraction, sublimation, vacuum mixing, vacuum reaction, absorption, vacuum filtration and conveying materials in the chemical industry are all completed with the help of vacuum equipment. Because there are flammable and explosive raw materials, low boiling point organic solvents and volatile strong acids in the raw materials.

The vacuum pump used in the specific application is different.

Some vacuum towers are required to pump negative pressure.

The miniature vacuum pump used in the pharmaceutical machine is required to be a diaphragm type miniature vacuum pump, which requires 1Pollution-free transmission, maintenance-free; 2.High vacuum, large flow rate and strong suction; 3.

It can be operated continuously. 4.Can be installed in any orientation; 5.

The medium is allowed to be enriched with water vapor. In particular, to pollution-free transmission, high vacuum, large flow, strong suction, these requirements are very strict, from the micro vacuum pump market I recommend that you first use the "Chengdu Qihai Electromechanical Manufacturing ****" VBH1028 pump, this pump can fully meet your requirements, many pharmaceutical companies are using this pump on the pharmaceutical machine.

VCH1028 parameters: the power supply is DC power supply, the voltage is 24VA, and the load current is less than; Flow rate 28L min; Absolute vacuum 10kpa; Weight; Volume: 205*78*114mm.

Description: 1. Special attention should be paid to the selection

The suction end of the miniature vacuum pump can be loaded with large loads, or even completely blocked, which is normal operation.

The exhaust end of the micro vacuum pump must be unobstructed and there must not be any damping elements in the exhaust line! Otherwise, select FM or FAA or PCF series products.

2. All specifications use DC power supply. When ordering, please be sure to indicate the working voltage, such as VCH1028-24V.

3. The smaller the vacuum value, the stronger the suction power.

4. Due to the need for product improvement, the technical data will change without notice!

5. The working medium of the miniature vacuum pump:

The gas pumped by the micro vacuum pump must be non-corrosive and oil-free, but allowed to be rich in land-buried water vapor.

This series of products are divided into two types: normal temperature medium type and high temperature medium type according to the tolerable medium gas temperature.

The order of high-temperature medium type products needs to be specially marked, such as VCH1028 24V (high-temperature medium type).

Normal temperature medium type 0 50, high temperature medium type 0 100, prohibit the medium gas containing ice particles and other solid particles!

6. Unless otherwise specified, the peak flow at 20 and standard atmospheric pressure is referred to as the flow.

Instructions for use:1The working environment of the miniature vacuum pump.

Ambient temperature: 0 40, the pump should not be exposed to the sun outdoors, and should work in a clean environment.

Ambient relative humidity: 75%.

2.Noise and silencer (optional).

When there is an air flow through the pump, the noise is large, and when the pumping is close to the vacuum, the noise will be large and not cracked, and the noise will be reduced.

When a silencer is connected to the air duct system, it has a certain effect. Depending on the specific situation of the air system and the conditions of use, the sound attenuation effect is different.

Precautions: 1 The exhaust end must be kept unobstructed. Do not place any damping elements in the exhaust line! Failure to do so may damage the miniature pump and even endanger life.

2 Foreign objects must not fall into the air nozzle, otherwise it will damage the micro pump!

There is no doubt about choosing a water ring vacuum pump. Here's why:

1. The pumped medium contains uncondensed steam, and the steam will cause damage to the mechanical pump that needs lubricating oil, but not to the water ring pump.

2. The concentrator requires a vacuum degree between one and a li, which is the best working pressure of the water ring pump.

3. The installation space of the water ring vacuum pump is small, and the installation is fast and the operation is simple (the water jet pump needs a pool, drop, etc., and it covers a large area and is troublesome to install).

4. There is almost no need for maintenance (the jet pump needs to be cleaned frequently, and the pressurized water pump often needs to be repaired).

I specialize in selling vacuum pumps, and there are various forms of vacuum pumps. Jujubes.

The choice of vacuum pump depends on your requirements for vacuum degree and environment.

Anex Hengnate Iwata vacuum pump 0---100pa has many models, oil-free, scroll type, low skin consumption, air cooling, energy saving and environmental protection, new choice.

Vacuum pumps are used in many industries, and the vacuum pumps selected in different industries are different, there are many types of vacuum pumps, and the appropriate vacuum pump should be selected according to the industry of the relevant industry, and the task of the vacuum pump is to use mechanical, physical, chemical, physicochemical and other methods to pump the container to obtain and maintain the vacuum device. Vacuum pumps and other equipment (such as vacuum vessels, vacuum valves, vacuum measuring instruments, connecting pipelines, etc.) constitute vacuum systems, which are widely used in electronics, metallurgy, chemical industry, food, machinery, medicine, aerospace and other departments.

According to its working principle, it is basically divided into two types: gas transfer pump and gas capture pump.

The gas transfer pump comprises: 1, liquid ring vacuum pump (water ring vacuum pump) 2, reciprocating vacuum pump 3, rotary vane vacuum pump 4, fixed disc vacuum pump 5, slide valve vacuum pump 6, cycloidal vacuum pump 7, dry vacuum pump 8, roots vacuum pump 9, molecular vacuum pump 10, traction molecular pump 11, compound vacuum pump 12, water jet vacuum pump 13, gas jet pump 14, steam jet pump 15, diffusion pump and so on.

Gas capture pumps include: adsorption pumps and cryogenic pumps.

At present, the most widely used in the industry are water ring vacuum pumps and rotary vane vacuum pumps.
