Product Details

Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Product overview

Desktop circulating water vacuum pump series to circulating water as the working fluid, the use of fluid jet, generating negative pressure for the jet vacuum pump. For evaporation, distillation, crystallization, drying, sublimation, filtration decompression, degassing and other domestic vacuum conditions, especially suitable for colleges and universities, scientific research institutes, chemical, pharmaceutical, biochemical, food, pesticide, agricultural engineering, biological engineering and other industries laboratory and small test.

SHB-III circulating water vacuum pump features:

● Recycling water to save valuable water resources.

More than 35% power saving than other types of vacuum pump.

● Special fluid muffler, reduce the water gas, so that the vacuum is higher and more stable; reduce gas-liquid friction, reduce noise.

● Double tap, double display, can be used alone or in parallel.

Acid, alkali, solvent corrosion.

●The motor is sealed by the motor manufacturer ODM, fluorine rubber, and there is no corrosive gas intrusion inside the motor.

▲ The water in the sink needs to be replaced regularly to ensure pure water quality, ensure the vacuum degree and avoid dirt stains.

▲ Can be used to extract corrosive gas, need to shorten the water cycle.

◆ SHB-Ⅲ: The pump body is made of PP, which is more suitable for acid gas, and others are the same as SHB-ⅢA.
