Water Circulating Vacuum Pump

Water circulating vacuum pump is a kind of vacuum pump. The ultimate vacuum it can obtain is 2000-4000 Pa, and the series atmospheric ejector can reach 270-670 Pa.

The water circulating vacuum pump adopts double taps, 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, stainless steel movement and anti-corrosion material movement. Manufactured with strong acid, alkali and corrosion resistance, this machine has acid resistance, alkali resistance and corrosion resistance; no pollution, low noise, easy to move, and a vacuum regulating valve can also be installed 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.

Water Circulating Vacuum Pump Working Principle:

The working medium of the circulating water absorber vacuum pump is water, which belongs to the centrifugal mechanical pump. The impeller rotor is installed in the cylindrical pump casing. Its blades are forward curved. when the impeller rotates. Under the action of centrifugal force, water forms a water ring that swirls along the pump casing. The water ring runs relative to the blades. The volume of the space between two adjacent blades changes periodically. When the blade rotates from the upper right to the lower. The water between every two leaves is pushed outward. Make the volume of this space gradually increase from small to large. It reaches the maximum at the bottom. Then the gas is sucked in from the axial suction port. And when the blade rotates from the bottom to the top left. The water moves relative to the axis. The space between the two leaves gradually changed from large to small. The inhaled gas is gradually compressed and finally discharged through the exhaust port. With the steady rotation of the impeller. Each volume wheel changes repeatedly. Make the suction and exhaust process continue.

Models of Water Circulating Vacuum Pump:

ZZKD Machineryhas been focusing on the R&D and production of water circulating vacuum pumps for many years. Water circulating vacuum pumps are one of our main products. After several upgrades, there are more and more models and types of water circulating vacuum pumps, and their functions are also becoming more and more Complete.

Water circulating vacuum pumps are divided into vertical water circulating vacuum pumps and desktop water circulating vacuum pumps. There are two models of desktop water circulating vacuum pumps: SHZ-D (double meters and double taps) and SHZ-D (four meters and four taps), There is one type of vertical water circulating vacuum pump: SHZ-C.

The Structure of Water Circulating Vacuum Pump:

Water circulating vacuum 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.

Structural Features of Water Circulating Vacuum Pump:

1. Multi-meter and multi-tap design, can be used alone or in parallel

2. The pump head is made of corrosion-resistant materials

3. The shell is made of high-strength ABS engineering plastics at one time

4. The core motor part is a stainless steel motor shaft core, which will not rust after long-term work

5. Turbine duct structure ensures the maximum and fastest flow of water

6. Equipped with a fluid muffler to reduce friction noise between gas and liquid in water

7. All-copper coil AC motor with cooling fan at the tail, which can work continuously

8. A check valve is installed on the exhaust pipeline to prevent accidental shutdown during vacuuming

How Does Water Circulating Vacuum Pump Work?

The working principle of water circulating vacuum pump: There is a proper amount of water in the pump body 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 which 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, the gas compressed in the pump body will be discharged out of the pump due to the high pressure of the gas, so as to achieve the function of pumping and vacuuming.

How to Use Water Circulating Vacuum Pump:

1. Preparation: Put the multi-purpose vacuum pump for water circulation on the workbench. When using it for the first time, open the top cover of the water tank and inject clean cold water (you can also add water through the drain hose). When the water level is about to rise to the height of the overflow nozzle behind the water tank Stop adding water when the machine is turned on, and do not add water after restarting the machine repeatedly. 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. When the multi-purpose vacuum pump for water circulation needs to work continuously for a long time, the water temperature in the water tank will rise, which will affect the vacuum degree. At this time, the water discharge hose can be connected to the water source (tap water), and the overflow nozzle can be used as the drainage outlet. Proper control The flow of tap water can keep the water temperature in the water tank from rising and make the vacuum stable.

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. , Turn the circulating water switch to the ON position to realize circulating cooling water supply.

Features of Water Circulating Vacuum Pump:

1. The pump adopts double taps and is equipped with two vacuum gauges, which can be used alone or in parallel.

2. The main engine adopts stainless steel and anti-corrosion material movement, and the box body is special anti-corrosion engineering plastics. For operations containing acetone; chlorine spinning and other organic chemicals. It has corrosion resistance and dissolution resistance.

3. Important components such as the ejector, tee, check valve, and suction nozzle of the pump are made of copper or anti-corrosion engineering plastics.

4. The pump is equipped with water inlet and outlet joints to provide cooling circulation to the reaction device and clean the box.

5. This pump has the advantages of no oil, no pollution, corrosion resistance, low noise, no vibration, and convenient movement.

6. This pump can be equipped with rotary evaporator, vacuum freeze drying oven, magnetic stirrer and other instruments to carry out multifunctional chemical reaction operations and drug analysis under low temperature conditions.

Precautions for Using Water Circulating Vacuum Pump:

1. The pool must be filled with water before starting the machine, and the inlet valve of the water circulation vacuum pump is opened. It is strictly forbidden to dehydrate, idling and reverse 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. For the steam-water series jet pump, 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 Vacuum.

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.
