Overview
Function Introduction
Laboratory water circulation pump is the latest designed vacuum pump model with circulating water as working fluid, and it adopts jet technology to create negative pressure.
Laboratory water circulation pump can meet the needs of larger rotary evaporators and glass reactors, which also serve many devices at the same time.
The laboratory water circulation pump is composed of water tank, water pump, pressure gauge, check valve and other components. It is designed with circulating water as the working fluid and the principle of negative pressure generated by jet flow. Widely used in suction filtration, evaporation, distillation, crystallization, decompression, sublimation and other operations, it is an ideal equipment for laboratories in universities, pharmaceuticals, chemicals, food processing and other fields.
What is the working principle and structure of the laboratory water circulation pump?
The working water of the laboratory water circulation pump is discharged together with the compressed gas. Therefore, the water ring needs to be continuously replenished with new cold water. To maintain a stable water ring thickness and temperature. The water ring acts as a "liquid piston". There is also heat dissipation (for the compression process). Sealing (between the impeller and the gas distribution plate), cooling (shaft seal), etc.
What are the characteristics of laboratory water circulation pump?
1. Due to the water circulation operation, the water added to the water tank can be recycled, and the water saving effect is obvious.
2. Multifunctional comprehensive effect.
3. The machine is connected to the tap water source. By supplementing the water injection source in an appropriate amount, the temperature and water quality of the vacuum circulating water can be kept unchanged under the condition of continuous operation for a long time, which can ensure that the vacuum degree drops and realize the supply of circulating cooling water. .
4. The machine can work independently or simultaneously. Each suction nozzle is equipped with a vacuum gauge, which can easily observe the vacuum degree. There is a check valve on the suction pipeline, which can prevent the circulating water from flowing back into the vacuumed equipment when it is shut down outside of the vacuum operation.
Features
Laboratory water circulation pump Features:
1. One machine with multi-pipe operation, where three sets (five sets )of air exhauster are fixed and can be used independently or parallelly, compared with desktop pump, swept volume is bigger, applied to large swept volume vacuum needs.Corrosion resistance, free-pollution, stable performance, low noise and durable.
2. Host stainless steel movement and anti-corrosive movement models.
3. The water-line target, light shows high, medium and low. 4 trundles make the movement easily.
4. Pump body and impeller are made of corrosion protection polypropylene. Special customized motor by well-known manufacturers, fluorine rubber mechanical seal to keep no corrosive gas into the motor.
Advantages of laboratory water circulation pump:
1. Recycle water to save precious water resources.
2. More than 35% power saving than other types of vacuum pumps.
3. Special fluid muffler to reduce gas in water.
4. Double-tap, double-display, can be used alone or in parallel.
5. Acid, alkali, solvent corrosion.
6. The motor is produced by the motor manufacturer, sealed with fluorine rubber, and there is no corrosive gas intrusion inside the motor.
7. The water in the sink needs to be replaced regularly to ensure the purity of the water, ensure the vacuum, and avoid scale stains.
8. It can be used to extract corrosive gases, and the water change cycle needs to be shortened.
Precautions for the use of laboratory water circulation pump:
1. Keeping the water clean is the key to the long-term stable operation of the equipment.
2. Dust and solid matter cannot be pumped.
3. Certain corrosive gases can lead to poor water quality in the water tank, produce air bubbles, and affect the vacuum degree, so attention should be paid to changing the water in a continuous cycle.
4. For special strong corrosive gases, it should be carefully judged whether it reacts with the materials used in this equipment, and use it with caution.
5. If the vacuum degree does not increase, first judge whether the pumped container is leaking or the leather tube is loose.
6. The motor of the laboratory water circulation pump does not turn, and the power supply or fuse should be checked.
