What Is the Difference Between Dry and Wet Vacuum Pumps?
Dry and wet vacuum pumps are two distinct types of pumps that differ in their operating principles and applications. Here’s a detailed explanation of the differences between them:
Dry Vacuum Pumps:
Dry vacuum pumps operate without the use of any lubricating fluid or sealing water in the pumping chamber. They rely on non-contact mechanisms to create a vacuum. Some common types of dry vacuum pumps include:
1. Rotary Vane Pumps: Rotary vane pumps consist of a rotor with vanes that slide in and out of slots in the rotor. The rotation of the rotor creates chambers that expand and contract, allowing the gas to be pumped. The vanes and the housing are designed to create a seal, preventing gas from flowing back into the pump. Rotary vane pumps are commonly used in laboratories, medical applications, and industrial processes where a medium vacuum level is required.
2. Dry Screw Pumps: Dry screw pumps use two or more intermeshing screws to compress and transport gas. As the screws rotate, the gas is trapped between the threads and transported from the suction side to the discharge side. Dry screw pumps are known for their high pumping speeds, low noise levels, and ability to handle various gases. They are used in applications such as semiconductor manufacturing, chemical processing, and vacuum distillation.
3. Claw Pumps: Claw pumps use two rotors with claw-shaped lobes that rotate in opposite directions. The rotation creates a series of expanding and contracting chambers, enabling gas capture and pumping. Claw pumps are known for their oil-free operation, high pumping speeds, and suitability for handling dry and clean gases. They are commonly used in applications such as automotive manufacturing, food packaging, and environmental technology.
Wet Vacuum Pumps:
Wet vacuum pumps, also known as liquid ring pumps, operate by using a liquid, typically water, to create a seal and generate a vacuum. The liquid ring serves as both the sealing medium and the working fluid. Wet vacuum pumps are commonly used in applications where a higher level of vacuum is required or when handling corrosive gases. Some key features of wet vacuum pumps include:
1. Liquid Ring Pumps: Liquid ring pumps feature an impeller with blades that rotate eccentrically within a cylindrical casing. As the impeller rotates, the liquid forms a ring against the casing due to centrifugal force. The liquid ring creates a seal, and as the impeller spins, the volume of the gas chamber decreases, leading to the compression and discharge of gas. Liquid ring pumps are known for their ability to handle wet and corrosive gases, making them suitable for applications such as chemical processing, oil refining, and wastewater treatment.
2. Water Jet Pumps: Water jet pumps utilize a jet of high-velocity water to create a vacuum. The water jet entrains gases, and the mixture is then separated in a venturi section, where the water is recirculated, and the gases are discharged. Water jet pumps are commonly used in laboratories and applications where a moderate vacuum level is required.
The main differences between dry and wet vacuum pumps can be summarized as follows:
1. Operating Principle: Dry vacuum pumps operate without the need for any sealing fluid, while wet vacuum pumps utilize a liquid ring or water as a sealing and working medium.
2. Lubrication: Dry vacuum pumps do not require lubrication since there is no contact between moving parts, whereas wet vacuum pumps require the presence of a liquid for sealing and lubrication.
3. Applications: Dry vacuum pumps are suitable for applications where a medium vacuum level is required, and oil-free operation is desired. They are commonly used in laboratories, medical settings, and various industrial processes. Wet vacuum pumps, on the other hand, are used when a higher vacuum level is needed or when handling corrosive gases. They find applications in chemical processing, oil refining, and wastewater treatment, among others.
It’s important to note that the selection of a vacuum pump depends on specific requirements such as desired vacuum level, gas compatibility, operating conditions, and the nature of the application.
In summary, the primary distinction between dry and wet vacuum pumps lies in their operating principles, lubrication requirements, and applications. Dry vacuum pumps operate without any lubricating fluid, while wet vacuum pumps rely on a liquid ring or water for sealing and lubrication. The choice between dry and wet vacuum pumps depends on the specific needs of the application and the desired vacuum level.
What Is a Vacuum Pump, and How Does It Work?
A vacuum pump is a mechanical device used to create and maintain a vacuum or low-pressure environment within a closed system. Here’s a detailed explanation:
A vacuum pump operates on the principle of removing gas molecules from a sealed chamber, reducing the pressure inside the chamber to create a vacuum. The pump accomplishes this through various mechanisms and techniques, depending on the specific type of vacuum pump. Here are the basic steps involved in the operation of a vacuum pump:
1. Sealed Chamber:
The vacuum pump is connected to a sealed chamber or system from which air or gas molecules need to be evacuated. The chamber can be a container, a pipeline, or any other enclosed space.
2. Inlet and Outlet:
The vacuum pump has an inlet and an outlet. The inlet is connected to the sealed chamber, while the outlet may be vented to the atmosphere or connected to a collection system to capture or release the evacuated gas.
3. Mechanical Action:
The vacuum pump creates a mechanical action that removes gas molecules from the chamber. Different types of vacuum pumps use various mechanisms for this purpose:
– Positive Displacement Pumps: These pumps physically trap gas molecules and remove them from the chamber. Examples include rotary vane pumps, piston pumps, and diaphragm pumps.
– Momentum Transfer Pumps: These pumps use high-speed jets or rotating blades to transfer momentum to gas molecules, pushing them out of the chamber. Examples include turbomolecular pumps and diffusion pumps.
– Entrapment Pumps: These pumps capture gas molecules by adsorbing or condensing them on surfaces or in materials within the pump. Cryogenic pumps and ion pumps are examples of entrainment pumps.
4. Gas Evacuation:
As the vacuum pump operates, it creates a pressure differential between the chamber and the pump. This pressure differential causes gas molecules to move from the chamber to the pump’s inlet.
5. Exhaust or Collection:
Once the gas molecules are removed from the chamber, they are either exhausted into the atmosphere or collected and processed further, depending on the specific application.
6. Pressure Control:
Vacuum pumps often incorporate pressure control mechanisms to maintain the desired level of vacuum within the chamber. These mechanisms can include valves, regulators, or feedback systems that adjust the pump’s operation to achieve the desired pressure range.
7. Monitoring and Safety:
Vacuum pump systems may include sensors, gauges, or indicators to monitor the pressure levels, temperature, or other parameters. Safety features such as pressure relief valves or interlocks may also be included to protect the system and operators from overpressure or other hazardous conditions.
It’s important to note that different types of vacuum pumps have varying levels of vacuum they can achieve and are suitable for different pressure ranges and applications. The choice of vacuum pump depends on factors such as the required vacuum level, gas composition, pumping speed, and the specific application’s requirements.
In summary, a vacuum pump is a device that removes gas molecules from a sealed chamber, creating a vacuum or low-pressure environment. The pump accomplishes this through mechanical actions, such as positive displacement, momentum transfer, or entrapment. By creating a pressure differential, the pump evacuates gas from the chamber, and the gas is either exhausted or collected. Vacuum pumps play a crucial role in various industries, including manufacturing, research, and scientific applications.

Servicing and inspection
(1) Verify all fasteners and locating pins circumstances no matter whether they are loosening.
(2) Always examine whether the leakage phenomenon of the physique.
(3) Pay out interest to lubrication, amount of grease and noises when running,
decide no matter whether it operates underneath the necessary problems.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop point ≥
190ºC). Exchange the lubricant and grease soon after very first 200 several hours running, and exchange
once again soon after a moth operating. Later on, replace the lubricant and grease in accordance to the
setting and lubricant (grease) top quality suggest a suitable substitution for 3
months.
(5) Always check the inlet air filter, clean or change the filter in time.
(six) Blower overload occasionally not immediately shown, so pay out consideration to
the consumption and exhaust stress, bearing temperature and the recent increase traits
of motor to figure out regardless of whether the blower performs typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on factors to make sure the CZPT
requirements after assembling.
(eight) When newly machine or overhaul, the oil tank should be cleaned just before use
and suggest substitute all grease right after 8 hrs operating.
