dry scroll pump

On the basis of absorbing many foreign vacuum pumps, the dry scroll pump is an environmental protection vacuum pump with high cost performance, which represents the future development direction of vacuum pump.

dry scroll pump application:

Medical instruments, biological products and drug preparation, food, drug packaging, oil and gas recovery, film preparation, large science engineering and chemical analysis, semiconductor, microelectronics, solar energy, material processing and other equipment.

dry scroll pump performance characteristics :

1. Environmental protection – no oil, no water and no pollution, clean vacuum can be obtained

2. Maintenance free, simple operation and long maintenance cycle

3. Energy saving and low energy consumption

4. Air cooling without water cooling

5. Strong steam pumping capacity and recyclable materials

6. Small vibration, low noise, compact structure, convenient installation and movement

7. Wide working vacuum area, continuous operation from extreme vacuum to atmospheric pressure

dry scroll pump technical specifications:

dry scroll pump working principle:

The dry-type scroll vacuum pump is composed of two involute spiral curves, namely, a static scroll and a dynamic scroll. When the moving scroll is installed eccentrically, the static scroll and the moving scroll form a crescent shaped cavity. With the rotating of the whirlpool, the moon bud cavity continuously rotates and compresses inward, and finally discharges from the middle to the air outlet. The dynamic scroll plate operates continuously, and the gas enters from the air inlet and exits from the air outlet to form a vacuum.

dry scroll pump design:

1. Maintenance free design, saving labor cost

2. Environmental protection design, water saving, oil saving and energy saving

3. Multi working condition design to meet the needs of different gas substances

4. Exclusive patent

5. Multi specification design to meet different flow requirements

6. High vacuum

7. Multi type interface — KF vacuum quick release flange and thread interface

8. High performance coupling

9. The shock foot design can be directly placed on the ground

dry scroll pump main configuration and materials:

1. Scroll: special aluminum alloy

2. Seal: Viton or Buna

3. Bearing: high quality bearing

4. Motor: high quality motor (or imported famous brand motor)

dry scroll pump main process:

1. Advanced fine processing technology

2. Precise assembly process

3. Comprehensive test process

4. Advanced coating process

5. Export fumigation free packaging

dry scroll pump spare parts:

1. Maintenance package (one set of seal, shaft seal, bearing, special grease)

2. One set of face seal / one set of special grease / one set of seals for large maintenance package

Advantages and disadvantages of dry scroll pump (dry pump) and oil vane vacuum pump (oil pump):

1. Dry vacuum pump: no oil leakage, oil injection, oil return and oil smoke

Oil vacuum pump: oil leakage, oil injection, oil return and oil smoke

2. Dry vacuum pump: it can pump water vapor

Oil vacuum pump: the steam will emulsify the vacuum pump oil, quickly reduce the service life of the vacuum pump oil, and the vacuum pump will be damaged if not replaced in time

3. Dry vacuum pump: it can pump chemical solvent vacuum (such as acetone, alcohol, gasoline, etc.)

Oil vacuum pump: pump contains chemical solvent, which will decompose the vacuum pump oil; if not replaced in time, it will damage the vacuum pump

4. Dry vacuum pump: maintenance free, labor and material cost saving

Oil vacuum pump: regular oil change, short maintenance time, special personnel are required to take care of it

5. Dry vacuum pump: high stability, long trouble free time

Oil vacuum pump: general stability

6. Dry vacuum pump: it can be used in a clean and dust-free environment without product pollution

Oil vacuum pump: it can not be used in clean and dust-free environment, which will produce oil vapor

7. Dry vacuum pump: valuable materials can be recycled

Oil vacuum pump: generally not recyclable

8. Dry vacuum pump: low noise, low vibration

Oil vacuum pump: the belt oil pump has large noise and vibration; the direct oil pump has low noise and vibration

9. Dry vacuum pump: simple structure, compact, low failure rate

Oil vacuum pump: belt oil pump has complex structure and large volume; direct oil pump has complex structure and small volume

10. Dry vacuum pump: high one-time investment, but low maintenance cost in the future (with average economy)

Oil vacuum pump: low one-time input, but high maintenance cost in the future (often replace vacuum pump oil, oil filter, oil mist separator, etc.)

11. Dry vacuum pump: light weight, new material, low transportation cost

Oil vacuum pump: heavy weight, high transportation cost

12. Dry vacuum pump: it can be installed and fixed vertically and horizontally

Oil vacuum pump: it can only be installed horizontally, otherwise the pump oil will overflow
13. Dry vacuum pump: meet the vacuum demand of high-end industry and high-end product market

Oil vacuum pump: usually low-end industry

14. Dry vacuum pump: wide working vacuum area, continuous operation from ultimate vacuum to atmospheric pressure

Oil vacuum pump: the two-stage oil pump is generally better to operate continuously below 3000 PA
