What is Rocking piston type dry vacuum pumps?
Rocking Piston type dry vacuum pump is a mechanical vacuum pump that transfers gas by the reciprocating motion of a piston interlocking with an eccentric rotating shaft.
Features of Rocking piston type dry vacuum pumps
Since this is an oil-less pump, backflow of air through the sliding part between the cylinder and piston ring is unavoidable. Because of its simple structure, this pump has low ultimate pressure. However, it can obtain stable pressure in a low vacuum region.
Some models can also be used as a pressurizing source for compressors. The pump is widely used in printed board mounting equipment, vacuum packaging machines, material adsorption transfer equipment, labeling machines, printing ink degassing machines, printing machines, photograph plate making machines, screen printing machines, degassing machines, burying machines, baking furnaces, suction machines, automobile exhaust gas analyzers, refrigerant recovery device, plasma cutting equipment.
Strength: The pump has a simple structure and is easy to maintain.
Weakness: The pump can not obtain a high vacuum.

Mechanism of Rocking piston type dry vacuum pumps
When the eccentric cam directly connected to the motor rotates, the piston moves up and down in the cylinder while swinging. The space inside the cylinder changes due to the vertical movement of the piston, and the gas is transported by repeating intake, compression and exhaust.

How Does a Piston Vacuum Pump Work?
A piston vacuum pump, also known as a reciprocating vacuum pump, operates using a piston mechanism to create a vacuum. Here’s a detailed explanation of its working principle:
1. Piston and Cylinder Assembly:
– A piston vacuum pump consists of a piston and cylinder assembly.
– The piston is a movable component that fits inside the cylinder and creates a seal between the piston and cylinder walls.
2. Intake and Exhaust Valves:
– The cylinder has two valves: an intake valve and an exhaust valve.
– The intake valve allows gas or air to enter the cylinder during the suction stroke, while the exhaust valve allows the expelled gas to exit during the compression stroke.
3. Suction Stroke:
– During the suction stroke, the piston moves downward, creating a vacuum within the cylinder.
– As the piston moves down, the intake valve opens, allowing gas or air from the system being evacuated to enter the cylinder.
– The volume within the cylinder increases, causing a decrease in pressure and the creation of a partial vacuum.
4. Compression Stroke:
– After the suction stroke, the piston moves upward during the compression stroke.
– As the piston moves up, the intake valve closes, preventing backflow of gas into the evacuated system.
– Simultaneously, the exhaust valve opens, allowing the gas trapped in the cylinder to be expelled.
– The upward movement of the piston reduces the volume within the cylinder, compressing the gas and increasing its pressure.
5. Expulsion of Gas:
– Once the compression stroke is complete, the gas is expelled through the exhaust valve.
– The exhaust valve then closes, ready for the next suction stroke.
– This process of alternating suction and compression strokes continues, gradually reducing the pressure within the evacuated system.
6. Lubrication:
– Piston vacuum pumps require lubrication for smooth operation and to maintain the airtight seal between the piston and cylinder walls.
– Lubricating oil is often introduced into the cylinder to provide lubrication and help maintain the seal.
– The oil also helps to cool the pump by dissipating heat generated during operation.
7. Applications:
– Piston vacuum pumps are commonly used in applications where high vacuum levels and low flow rates are required.
– They are suitable for processes such as laboratory work, vacuum drying, vacuum filtration, and other applications that require moderate vacuum levels.
In summary, a piston vacuum pump operates by creating a vacuum through the reciprocating motion of a piston within a cylinder. The suction stroke creates a vacuum by lowering the pressure within the cylinder, while the compression stroke expels the gas and increases its pressure. This cyclic process continues, gradually reducing the pressure within the system being evacuated. Piston vacuum pumps are commonly used in various applications that require moderate vacuum levels and low flow rates.
What Is the Energy Efficiency of Piston Vacuum Pumps?
The energy efficiency of piston vacuum pumps can vary depending on several factors. Here’s a detailed explanation:

3. Control Systems:
– The use of advanced control systems can optimize the energy consumption of piston vacuum pumps.
– Variable frequency drives (VFDs) or speed control systems can adjust the pump’s operating speed based on the demand, reducing energy consumption during periods of lower demand.
– Smart control algorithms and sensors can also help optimize the pump’s performance and energy efficiency.
4. System Design and Integration:
– The overall system design and integration of the piston vacuum pump within the application can impact energy efficiency.
– Proper sizing and selection of the pump based on the specific application requirements can ensure that the pump operates within its optimal efficiency range.
– Efficient piping and ducting design, as well as minimizing pressure losses and leaks, can further improve the overall energy efficiency of the system.
5. Load Profile and Operating Conditions:
– The load profile and operating conditions of the piston vacuum pump have a significant impact on energy consumption.
– Higher vacuum levels or flow rates may require more energy to be supplied by the pump.
– Operating the pump continuously at maximum capacity may lead to higher energy consumption compared to intermittent or variable load conditions.
– It’s important to evaluate the specific operating requirements and adjust the pump’s operation accordingly to optimize energy efficiency.
6. Comparing Efficiency Ratings:
– When comparing the energy efficiency of different piston vacuum pumps, it can be helpful to look for efficiency ratings or specifications provided by the manufacturer.
– Some manufacturers provide efficiency data or performance curves indicating the pump’s energy consumption at various operating points.
– These ratings can assist in selecting a pump that meets the desired energy efficiency requirements.
In summary, the energy efficiency of piston vacuum pumps can be influenced by factors such as design and technology, motor efficiency, control systems, system design and integration, load profile, and operating conditions. Considering these factors and evaluating efficiency ratings can help in selecting an energy-efficient piston vacuum pump for a specific application.
