Vacuum Pump for Rotary Evaporator

The vacuum pump for rotary evaporator is widely used in evaporation, crystallization, Condensation, vacuum filtration and other operations are often used in conjunction with a rotary evaporator. It is an ideal equipment for laboratories in universities, pharmaceuticals, chemicals, and food processing.

The vacuum pump for rotary evaporator is a new type of multi-purpose vacuum pump designed with circulating water as the working fluid and the principle of negative pressure generated by the jet. It provides vacuum conditions for chemical experiments and can provide circulating cooling water to the reaction device.

The vacuum pump for rotary evaporator body is equipped with an appropriate amount of water as the working fluid. When the impeller rotates, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring with approximately equal thickness that depends on the shape of the pump cavity. At this time, the ring-shaped vacuum pressure becomes smaller, and the impeller continues to rotate to suck gas from the interface, and the inlet is closed at this time. The inhaled gas is also compressed during the rotation of the impeller. When it is connected to the gas outlet, due to the high pressure of the gas compressed in the pump body, the gas will be discharged out of the pump, so as to achieve the function of pumping and vacuuming.

The vacuum pump for rotary evaporator adopts double-tap, which can be used alone or in parallel. It is equipped with two vacuum gauges. The newly improved anti-corrosion four-tap, can be used alone or in parallel. It is equipped with four vacuum gauges. It is made of stainless steel movement and anti-corrosion material movement. , has strong acid, alkali and corrosion resistance, this machine has acid resistance, alkali resistance and corrosion resistance; no pollution, low noise, easy to move, and can also be equipped with a vacuum regulating valve according to user needs. The water circulation vacuum pump is small in size, compact in structure and movable, low in noise, low in energy consumption, efficient and convenient for comprehensive utilization. The water vapor series jet vacuum unit has small air consumption, can obtain higher vacuum degree, works stably and is easy to use.

1. Preparation. Put the multi-purpose vacuum pump for circulating water on the workbench. When in use, open the top cover of the water tank and inject clean cold water (you can also add water through the water hose). When the water level is about to rise to the height of the overflow nozzle behind the water tank, stop adding water and repeat. You don't need to add water when you start the machine. Change the water at least once a week. If the water quality is seriously polluted and the usage rate is high, the time for changing the water must be shortened to keep the water in the water tank clean.

2. Vacuum operation. Connect the suction sleeve of the equipment that needs to be vacuumed tightly to the suction nozzle of the machine, turn off the cycle switch, turn on the power, and turn on the power switch to start the vacuuming operation. Through the vacuum gauge corresponding to the suction nozzle Vacuum can be observed.

3. By controlling the flow of tap water, the water temperature in the water tank can be kept from rising and the vacuum degree can be stabilized.

4. When it is necessary to provide cooling circulating water for the reaction device, on the basis of the operation in the previous item 3, connect the water inlet and outlet pipes of the device to be cooled to the circulating water outlet and water inlet at the rear of the machine respectively.

Vacuum pump for rotary evaporator features:

1. Before starting the machine, the pool must be filled with water, and the inlet valve of the water circulation vacuum pump is opened. It is strictly forbidden to dehydrate, idle and reverse, so as to prevent damage to the machine seal and pump.

2. Before use, you must carefully check whether the fasteners in each part are loose, and if they are loose, you must correct and tighten them.

3. Connect the jet pump in series, turn it on first and then turn on the steam, turn off the steam first when stopping to prevent damage to the water jet pump. When installing the steam pipeline, ensure that there is no water in the pipeline, and it must be kept level, otherwise it will affect the vacuum Spend.

4. Before shutting down, first vent or the vacuum degree drops below 0.092Mpa, and then shut down to prevent excessive vacuum from sucking back and damaging the check valve. If the check valve fails, please open the check valve cover to remove debris.

5. If the water temperature of the circulating water pool is too high, it will affect the exhaust volume and vacuum degree, and the water needs to be replaced or replenished in time.
