What is Vacuum Pump?

Vacuum pumps are mechanical devices that enable the removal of air and gas molecules from a sealed area to create an area devoid of air and/or gas. Generally, their purpose is to clean and seal. Vacuum pumps come in wet or dry variants depending on the media being pumped through them.

Advantages of Vacuum Pump
 

 

High vacuum degree

The vacuum pump has the characteristics of a high vacuum degree, which can evacuate the gas in the environment and put the object in a high vacuum environment. In the field of scientific research, a high-vacuum environment is crucial to the implementation of experiments.

High compression ratio

The compression ratio of the vacuum pump refers to the ratio of the gas volume at the pump inlet to the gas volume at the pump outlet. A large compression ratio indicates that the vacuum pump has high exhaust efficiency and can meet the needs of different occasions.

Enhanced efficiency

These pumps help create the most appropriate environment for various work processes, enabling you to achieve faster, more precise results. High-performing pumps can also conserve energy.

Low noise

The noise of the vacuum pump is usually low, which makes its application advantageous in noise-sensitive fields. For example, in the medical field, vacuum pumps are used to attract pollutants or liquids, and low-noise equipment is usually required.

Cost savings

Using vacuum pumps enables businesses to complete more projects faster and with fewer resources. High-quality pumps also require less preventive maintenance and repair service. When combined with their energy-efficient operation, they can lead to lower operating costs.

Energy saving and environmental protection

Compared with traditional gas exhaust devices, vacuum pumps can process and recycle gases, which can not only effectively reduce the emission of pollutants, but also achieve energy saving and environmental protection.

 

 

Vacuum Pump: Everything You Need to Know!

A vacuum pump’s main function is to change the pressure in a contained space to create a full or partial vacuum either mechanically or chemically. Pressure will always try to equalize across connected regions as gas molecules flow from high to low to fill the entire area of that volume. Therefore, if a new low-pressure space is introduced, gas will naturally flow from the high-pressure area to the new area of low-pressure until they are of equal pressure.

Types of Vacuum Pumps

There are several different types of vacuum pumps, and each will work best depending on how well you maintain your pump, the environment you’re using it in, and what you’re using it for. Some of the most commonly used vacuum pumps include:

 
 

Liquid ring

Liquid rings operate using a liquid. An impeller with an axis eccentric to the housing rotates the liquid, spinning the liquid out towards the impeller housing. This type of pump is common in environmental, textile, mining and chemical industries because of its air-purifying properties.

 
 
 

Articulated piston

An articulated piston pump works much like that of a car engine. When the piston moves down, air and gasses are pulled into an intake valve. When the piston moves back up, the air molecules are pushed out of the exhaust valve. They are well-suited for applications that require high suction and flow rates.

 
 
 

Claw

Claw vacuum pumps use two continually rotating rotors that never come in contact with each other. This rotation moves gasses and air from the intake side to the output side, pulling vacuum. These vacuum pumps are popular in the medical field because they are oil-free, eliminating the possibility of contamination.

 
 
 

Rotary vane

Rotary vane pumps use offset rotating vanes in a cylindrical case to create positive displacement. As the vanes move around the eccentric rotor, air and gas molecules get trapped between the vanes and are moved from the inlet to the outlet port, creating a vacuum.

 
 
 

Rotary screw

Rotary screw pumps also use positive displacement to create a vacuum. Two spiral-shaped rotors rotate in opposite directions. Rotary screw vacuum pumps are often used in industrial applications that handle clean gasses.

 
 
 

Diaphragm

Diaphragm vacuum pumps use positive displacement to move air and liquid. Two flexible walls move back and forth, forming a vacuum. The diaphragm walls’ motions simultaneously push and pull air and liquid in and out of the pump.

 

 

 

Uses Of Vacuum Pumps

Vacuum pumps can remove gas from a sealed enclosure to create a vacuum space and are widely used for the following processes and equipment:

COMPOSITE MOLDING 

A manufacturing method where you apply pressure to liquid state matrix material so it could turn into dry preformed reinforcing material.

01

PRODUCTION OF ELECTRIC LAMPS

Vacuum pumps are used to remove the air from the bulb to prevent the filament to heat up and burn itself out.

02

CUTTING GLASSES AND STONES

Industrial vacuum pumps are used to power suction cups which are the main cutting equipment for glass and stone cutting. 

03

AIRCRAFT INSTRUMENTS

Vacuum pumps are used in some flight instruments such as turn coordinator, attitude indicator, and heading indicator. It was also used to spin gyroscopes using the vacuum pressure it could create. 

04

WOODWORKS

Industrial vacuum pumps are used to hold, lift, laminate, and dry wood during woodworking processes and procedures.

Precautions for Use Vacuum Pump

 

 

1. The vacuum pump should be installed in a dry, well-ventilated place, avoiding direct sunlight and humid environment. At the same time, ensure that there are no obstacles around the vacuum pump for easy operation and maintenance.

 

2. Before using the vacuum pump, check whether the power supply, voltage and grounding are normal, and whether all components are intact. If there is any abnormality, it should be handled in time.

 

3. Before starting the vacuum pump, the water inlet valve should be opened first to fill the pump with water. Then, close the water outlet valve, start the motor, and observe whether the vacuum pump runs smoothly without abnormal noise and vibration.

 

4. During use, pay attention to observe the operation of the vacuum pump. If abnormal sound, vibration or temperature rise is found, stop the machine immediately for inspection.

 

5. During the operation of the vacuum pump, avoid frequent starting and stopping to avoid damage to the motor and seals. At the same time, the lubricating oil should be replaced regularly to keep the pump clean.

 

6. When stopping, the water inlet valve should be closed first, and then the motor should be turned off. After the water in the pump cools down, close the water outlet valve.

 

Vacuum Pump Maintenance
 

 

The maintenance of vacuum pumps is essential to ensure their long-term stable operation and extend their service life. Here are some key maintenance measures:

 

 

Daily maintenance

Includes regular cleaning of the pump body and components, removal of dust and sediment, and cleaning with a mild detergent and a soft brush to avoid damage to the pump body.

 
 

Lubrication maintenance

Proper lubrication can reduce wear and friction of the pump body and improve the working efficiency of the pump. It is recommended to regularly inject the required lubricant into the pump body according to the pump body instruction manual, paying attention to the type and use of the lubricant.

 
 

Check the operation of the motor

It is very important to check the operation of the motor regularly. Pay attention to check whether the motor is operating normally and whether the temperature is too high. If there is any abnormality, it should be handled in time.

 
 

Check the seal

Check the status of the seal regularly. If it is aged, deformed or damaged, it should be replaced in time to ensure the normal operation of the pump body.

 
 

Dust and humidity

In the event of power outages, shutdowns or other special circumstances, the vacuum pump should be turned off to prevent dust, moisture, etc. from affecting the vacuum pump.

 
 

Common faults and solutions

Solutions to problems such as leakage, oil gas, and contaminated oil include rechecking the seal or replacing the seal, adding some oil change corrections, or regular replacement and cleaning to ensure the oil in the pump is clean.

FAQ

Q: What is a vacuum pump used for?

A: Vacuum pumps are used to remove air and other wet gas and vapor particles from a system. Without a vacuum pump, these particles can cause a system to run inefficiently and can even corrode internal parts. Generally, the purpose of a vacuum pump is to clean and seal an area from the air or other gasses.

Q: What is the difference between a vacuum pump and a normal pump?

A: The main feature of vacuum pump is that it can form a vacuum, which can be seen from its name. This is what ordinary pump can't do, which is the main difference between the two. The vacuum pump relies on a rotating wheel. It rotates in the chamber, and the chamber is filled with fluid.

Q: What two functions does a vacuum pump perform?

A: Industrial oil flooded screw vacuum pumps have two major functions: pulling down and maintaining the required vacuum level. As a result of the two major functions, the screw vacuum pumps have to handle a great range of pressure ratios.

Q: What is the difference between a vacuum pump and an air pump?

A: The efficiency of each can be different as they aim to achieve different needs. A vacuum pump intakes air from a closed environment resulting in a pump process that is positive discharge with no high pressure, whereas an air compressor intake air from an open environment and compress the air with high pressure.

Q: What else can you use a vacuum pump for?

A: Examples include space simulation chambers, coating devices, semiconductor production, electron beam welding, and high-vacuum furnaces. Sputter ion pumps are ultra-high vacuum pumping units useful in accelerators, analytical instruments, and electron beam irradiators.

Q: Why run a vacuum pump?

A: A vacuum pump, in general, is an added benefit to any engine that is high performance enough to create a significant amount of blow-by. A vacuum pump will, in general, add some horsepower, increase engine life, keep oil cleaner for longer.

Q: What does a vacuum pump remove?

A: A vacuum pump removes air and moisture from the system before the system is damaged. The deeper and more complete the vacuum, the more moisture is removed, and the likelihood of system complications caused by unwanted water or other contaminants is reduced.

Q: What does the vacuum pump control?

A: A vacuum pump's main function is to change the pressure in a contained space to create a full or partial vacuum either mechanically or chemically. Pressure will always try to equalize across connected regions as gas molecules flow from high to low to fill the entire area of that volume.

Q: What are vacuum pumps good for?

A: Vacuum pumps are mechanical devices that enable the removal of air and gas molecules from a sealed area to create an area devoid of air and/or gas. Generally, their purpose is to clean and seal. Vacuum pumps come in wet or dry variants depending on the media being pumped through them.

Q: Does a vacuum pump push or pull air?

A: Our vacuum pumps utilize advanced technology to push air molecules and create a vacuum, ensuring efficient and reliable performance.

Q: Do vacuum pumps need to be vented?

A: Vacuum pumps which are used to evacuate systems containing toxic, corrosive or volatile substances must be vented into the building's exhaust system. Failure to properly vent the pump can result in contamination of the lab with hazardous chemical vapors.

Q: What are the uses of vacuum pump in daily life?

A: Vacuum pumps are used in a broad range of development fields and leading technology in academic, official, and commercial laboratories that develop semiconductor products, aerospace equipment, and medical products.

Q: What can damage a vacuum pump?

A: The most common causes of failure include: Poor maintenance: Poor practices like infrequent oil changes or failing to replace worn-out parts can lead to early failure. Wear and tear: Continuous usage for extended periods can also cause failure.

Q: What is the most efficient vacuum pump?

A: The rotary vane vacuum pump wins the vacuum efficiency test by direct comparison.

Q: Do vacuum pumps need water?

A: Vacuum pumps can either be “dry” or “wet”—based upon how the vacuum seal is generated within the pump. Dry pumps do not use water to generate the seal for the vacuum. Instead, they create vacuums with turbines (i.e., fans) or use positive dis- placement (e.g., vane pumps, claw pumps, piston pumps).

Q: What happens when the vacuum pump fails?

A: This could be the result of an improper application, especially if there's an inlet vacuum or added pressure at the outlet, which will need to be addressed. When a vacuum pump fails here, fuses can overheat and burn out, eventually leading to damage of the motor or start capacitor.

Q: Can a vacuum pump remove water?

A: Industrial processes frequently require the use of vacuum to remove water from products at reduced temperatures and pressures. Rotary oil-sealed pumps are often used for this duty, but unless auxiliary equipment is utilized the pumps load up with water and cannot reach required final low pressures.

Q: How do you know if you need a new vacuum pump?

A: If your vacuum pump overheats when operating or constantly shuts down because of overheating, you should consider replacing it. Replacing the vacuum pump will prevent heat-related damage and save you money on costly repairs. While HVAC vacuum pumps can be very durable, they will not last a lifetime if used regularly.

Q: What precautions should be taken when using a vacuum pump?

A: Ensure that pumps have belt guards in place during operation to prevent hands or loose clothing from getting caught in the belt pulley. Ensure that electrical cords and switches are free from defects. Do not place pumps in an enclosed, unventilated cabinet allowing heat and exhaust to build up.

Q: Is it necessary to have a vacuum pump?

A: A vacuum pump, in general, is an added benefit to any engine that is high performance enough to create a significant amount of blow-by. A vacuum pump will, in general, add some horse power, increase engine life, keep oil cleaner for longer.
