First, the scope of use of laboratory circulating water multi-purpose vacuum pump :

Circulating water type multi-purpose vacuum pump provides vacuum conditions for processes such as evaporation, distillation, crystallization, drying, sublimation, filtration, decompression, and degassing. It is especially suitable for colleges and universities, research institutes, chemical, pharmaceutical, biochemical, food, pesticide, and agricultural Laboratories and pilots in engineering, bioengineering and other industries.

Second, the working principle of the laboratory circulating water multi-purpose vacuum pump :

The circulating water type multi-purpose vacuum pump uses circulating water as the working fluid and uses the principle of negative pressure generated by the jet to operate to provide the vacuum pump conditions for the laboratory and can provide circulating cooling water like the reaction device. The working principle diagram is as follows:

  Third, the advantages of Shiding SHB-III circulating water multi-purpose vacuum pump compared to other manufacturers:

循环水式多用真空泵两表两抽头,在实验室抽有机溶剂抽劲儿大,抗腐蚀,真空度可达到0.098MPa ,可与实验室5升以下旋转蒸发仪配用抽真空,组成蒸馏提纯装置,体积小,节省空间,可以放在通风橱或实验台上。 1 SHB-III circulating water type multi-purpose vacuum pump with two tables and two taps, pumping organic solvents in the laboratory is strong, corrosion-resistant, and the vacuum degree can reach 0.098 MPa , which can be used with a laboratory rotary evaporator of less than 5 liters. Composed of distillation purification device, small size, save space, can be placed on a fume hood or laboratory bench. The special motor is made by the well-known motor manufacturer ODM. It is sealed with fluorine rubber, and there is no corrosive gas inside the motor. The main body is made of stainless steel and equipped with an external circulation device, and the vacuum degree is stable.

2 SHB-III circulating water multi-purpose vacuum pump water tank adopts newly developed special plastic material, which is resistant to corrosion and strong in solubility, especially for organic chemicals such as acetone and dichloromethane.

3 SHB-III vacuum pump The pump body and impeller (six flow channels, double seals) are stamped and formed from stainless steel, and the material meets the SUS standard; the housing, water tank, ejector, tee, check valve, and suction nozzle are made of PP. .

◆ SHB-ⅢA: The ejector and exhaust nozzle are made of stainless steel (ANSI standard), others are the same as SHB-Ⅲ.

◆ SHB-ⅢS: The pump body is made of PP material, which is more suitable for acid gas. Others are the same as SHB-Ⅲ.
◆ SHB-ⅢT: transparent water tank, easy to observe the water level and water quality, others are the same as SHB-ⅢA.

4 Adopt special fluid muffler, reduce the gas in water, make the vacuum degree higher and more stable.

5 Resistant to acids and alkalis, solvents.

6 Compared with other types of vacuum pumps, it can save electricity by more than 35%.

7 Circulating water type multi-purpose vacuum pump can circulate water and save precious water resources. Shorten the water change interval, which can be used to pump corrosive gas.

8 Compared with the products of the same industry at home and abroad, the products of Zhengzhou Great Wall Technology Industry and Trade Co., Ltd. have the characteristics of high ultimate vacuum and fast pumping speed. The new vacuum bottle after transformation has increased pumping speed by 30% on the original basis.

V. How to choose a circulating water multi-purpose vacuum pump:

1. SHB-III type is commonly used in laboratories. It is made of stainless steel. It is resistant to corrosion by organic solvents and organic solvents. It can also pump a small amount of acid gases. It only needs to change water frequently. It is widely used in laboratories and has high cost performance. A product.

2. If there are many strong acid gases pumped in the laboratory, it is recommended that you use SHB-IIIS circulating water multi-purpose vacuum pump. PP material is more suitable for strong acid corrosion resistance.


3. SHB-IIIA suction nozzle and jet are made of high-quality stainless steel, which has significant anti-corrosion effect, higher configuration than SHB-III, and good anti-corrosion performance.

 

4. Model SHB-IIIG is an export standard. The ejector and the exhaust nozzle are sprayed with Teflon (PTFE), and the fluororubber gas pipeline is known as the universal anticorrosion king in the circulating water multi-purpose vacuum pump. The experimental environment is harsh or corrosive, so SHB-IIIG is recommended.

5.SHB-IV double A type is double-sided, four-meter four-tap, four-tap simultaneous vacuum, four-meter display, for four operators to experiment at the same time, students can also turn on and off on either side, without affecting each other, reducing Laboratory costs.
