Overview
SHB-IIIS Benchtop circulating water multi-purpose vacuum pump is a laboratory vacuum equipment produced by GREATWALL. It uses water as the working fluid and generates negative pressure through the jet to vacuum, providing negative pressure conditions for evaporation, distillation, crystallization, drying, sublimation, decompression filtrate and other processes. The pump body of this model is made of PP material, which is more suitable for extracting acid gases.
Features
1. Recycle water to save water resources.
2. More than 35% power saving compared to other types of vacuum pumps.
3. Special fluid muffler, reducing the gas in the water to make the Vacuum Level higher, reducing gas-liquid friction to reduce noise.
4. Dual taps, dual displays, can be used alone or in parallel.
5. Acid and alkali solvent corrosion resistance.
6. The motor is provided by a familiar motor manufacturer and uses fluororubber sealing to prevent corrosion gases from invading the motor.
7. The SHB-IIIS model pump body is made of PP material, which is more suitable for acid gases.
Principle
The vacuum pump uses water as the working fluid. Its Working Principle is to use jet technology, when the water flow passes through the specific design of the jet at high speed, negative pressure (vacuum) will be generated in the area of the exhaust port, so as to realize the extraction of the closed system and provide the required vacuum environment for various experimental processes.
Applications
Universities & colleges, research institutes, laboratories and industrial trials in chemical, biochemical, food, pesticide, agricultural engineering, bioengineering and other industries.
Steps
Make sure the device power supply (220V 50Hz) is connected correctly.
2. Add purified water to a 15L PP water tank to the specified water level.
3. Connect the experimental device to one or two suction nozzles of the vacuum pump as required.
4. Turn on the power and start the vacuum pump.
5. Observe and monitor the system Vacuum Level through dual meters.
6. After use, turn off the power and disconnect the experimental device.
Notice
• The water in the sink needs to be replaced regularly to ensure that the water quality is pure and conducive to ensuring the Vacuum Level.
• When used to extract corrosion gas, it is necessary to shorten the water change cycle.
• The equipment is equipped with a check valve (countercurrent prevention valve) and overcurrent protection functions, please pay attention to safety when using it.
• Please select the appropriate model (e.g. SHB-IIIS) according to the nature of the extracted gas (e.g. acidic).
