What Are the Advantages of Scroll Pumps over Other Types of Pumps?

Compared with other types of pumps, scroll pumps have the following advantages:
1. Handling solid particles: The impeller of the scroll pump does not directly contact the liquid, so it can handle liquids containing a large amount of solid particles, such as sewage treatment and other fields.
2. Good self-cleaning performance: When the scroll pump is running, the liquid generates strong centrifugal force and vortex during the rotation process, which can automatically clean out the dirt in the pipeline, so as to maintain the performance of the scroll pump.
3. Can handle gas-containing liquids: The design structure of the scroll pump enables it to handle gas-containing liquids, such as gas-liquid separation in the chemical and petroleum industries.
4. Low noise: Scroll pumps run more smoothly than other types of pumps and are therefore quieter.
5. Energy saving: Scroll pumps are designed with less energy loss, and compared to other types of pumps, scroll pumps are more energy efficient.
6. Low maintenance cost: Due to the simple structure of the scroll pump, there is no need to replace the wearing parts frequently, so the maintenance cost is low.

What Are the Structural Features of the Vortex Pump?

The structural features of vortex pump mainly include the following aspects:
1. No mechanical seal: The vortex pump has no rotating parts in its construction and therefore does not require a mechanical seal. This makes the vortex pump last longer and requires less maintenance and upkeep.
2. Simple rotor structure: The rotor structure of vortex pump is simpler than traditional centrifugal pumps, consisting of a flat plate and a guide vane fixed on the shaft. This structural design makes the pump have high reliability and stability.
3. Not easy to block: The inlet and outlet of vortex pump are designed very simply, without complicated inlet and outlet conduits and rotating parts, so it is not easy to block, and is suitable for transporting solid particles or viscous liquids.
4. High efficiency and energy saving: The rotor structure of vortex pump makes it have high efficiency. At the same time, because there is no mechanical seal, the friction loss is small, which can reduce energy consumption and operating costs.
5. Low speed: The speed of vortex pump is generally low, so it has less noise and vibration, and it can also reduce the wear and failure rate of the pump.

What is the working principle of the Scroll Pumps?

1.Basic Design: A scroll pump consists of two main components: a stationary scroll and an orbiting (rotating) scroll. These scrolls are typically made of metal and have spiral-shaped profiles.
2.Stationary Scroll: The stationary scroll is fixed in place and has a spiral-shaped ridge on its surface. This spiral forms a series of involute or Archimedean spirals.
3.Orbiting Scroll: The orbiting scroll is mounted on an eccentric drive shaft that causes it to move in a circular or elliptical motion. This scroll also has a spiral-shaped depression that matches the stationary scroll's ridge.
4.Suction and Compression Process: As the orbiting scroll moves, it rotates around the stationary scroll. The spirals of the two scrolls interlock, creating moving pockets or chambers of varying sizes between them.
5.Suction Phase: During the suction phase, the pockets between the scrolls gradually increase in size as they move towards the pump's inlet. This expansion creates a low-pressure zone that draws in the fluid or gas from the external environment. This is the vacuum or low-pressure phase.
6.Compression Phase: As the scrolls continue to rotate, the pockets move towards the center of the pump, causing them to decrease in size. This reduction in volume compresses the fluid or gas within the pockets, increasing its pressure.
7.Discharge Phase: The compressed fluid or gas is then expelled from the center of the scrolls through the pump's outlet. This is the high-pressure phase.
8.Continuous Operation: The rotation and orbiting motion of the scrolls create a continuous process of suction, compression, and discharge. The interaction between the spirals of the stationary and orbiting scrolls effectively moves and compresses the fluid or gas.
9.Oil-Free Operation: Scroll pumps are known for their oil-free operation, making them suitable for applications where contamination or oil-based lubrication is not desired.
10.Quiet and Smooth: Scroll pumps are known for their quiet and smooth operation compared to some other types of pumps. This is due to the absence of reciprocating parts and valves.
