Problems solved by technology

[0006] 3. Roots vacuum pump: its working principle is to use the volume change generated by a pair of 8-shaped rotors to discharge air. This kind of pump has a high pumping rate (30-1200L / S), but its ability to maintain vacuum is poor. When working, it needs to be assisted by a rotary vane vacuum pump or a water ring vacuum
[0008] 5. Reciprocating plunger vacuum pump: its manufacturing vacuum degree is high, but the pumping rate is very low, and the equipment wears high

Embodiment Construction

[0024] High-speed turbo vacuum pump, including medium and low vacuum units, high vacuum unit, main vacuum pipeline 1 and automatic control cabinet 2.

[0025] The pumping medium and low vacuum units include a high-speed turbo blower 3 and a motor 4 . The pulley on the output shaft of the motor 4 is connected with the pulley on the input shaft of the high-speed turbo fan 3 by a belt. The high vacuum unit includes a volumetric vacuum machine 5 and a motor 6. The belt pulley on the output shaft of the motor 6 is connected with the belt pulley on the input shaft of the displacement vacuum pump through a belt. A vacuum pressure sensor A, a vacuum pressure sensor B and a vacuum gauge 7 are installed on the main vacuuming pipeline 1 . The main vacuuming pipeline 1 is connected to the air inlet of the high-speed turbo blower 3 through a branch pipe 8, and a solenoid valve C is installed on the branch pipe 8. The main vacuuming pipeline 1 is connected with the air inlet of the volum...

Abstract

The high speed turbine vacuum pump includes control cabinet, main vacuum pipeline with two vacuum pressure sensors, medium and low vacuum pumping unit including high speed turbine blower and its driving motor, and high vacuum pumping unit including volumetric vacuum machine and its driving motor. The main vacuum pipeline is connected to the inlet of the high speed turbine blower via one branch pipe with the first solenoid valve and to the volumetric vacuum machine via one other branch pipe with the second solenoid valve. The present invention has high speed turbine blower, very high air pumping rate, high vacuum and automatic operation, and may be used widely in different industries.

Description

(1) Technical field [0001] The invention relates to a vacuum pump, in particular to a high-speed turbo vacuum pump capable of producing high vacuum in a very short time. (2) Background technology [0002] Vacuum pump is the main equipment for making vacuum, widely used in metallurgy, petroleum, chemical industry, food, aviation, aerospace, pharmaceutical, sugar, printing and dyeing, ceramics, environmental protection, electronics and scientific research and other industries. [0003] The types of vacuum pumps currently being widely used are: [0004] 1. Water ring vacuum pump: It needs a large amount of water as the working fluid when it works, and the air is wrapped and discharged, and its pumping rate is low (the pumping volume is generally 1.5-0.8m 3 / min) wastes a lot of water. [0005] 2. Rotary vane vacuum pump: its working principle is to use the volume change of the rotary scribing to discharge the air, and its pumping rate is low, generally in the range of 2 to 70...
