Description

Technical Field

[0001] This utility model relates to a vacuum pump assembly structure. Background Technology

[0002] With the rapid development of China's economy and the acceleration of its industrialization process, vacuum pumps have become indispensable equipment in various sectors of the national economy, widely used in manufacturing, chemical, food, home appliance, and new energy industries. The rapid development of these industries has provided a vast market for Roots vacuum pumps.

[0003] Vacuum pumps typically use Roots blowers. However, with prolonged operation, existing vacuum pumps are prone to rapid aging of the Roots blowers, resulting in poor sealing and oil leakage. Utility Model Content

[0004] This utility model proposes a vacuum pump assembly structure, including a pump frame, a resistive silencer, a first Roots blower, a second Roots blower, an inlet filter pipe, and a silencer weldment. The first and second Roots blowers are arranged vertically, and a first pump connecting pipe is provided between the first and second Roots blowers. Multiple sprayers are provided on the first pump connecting pipe, and the multiple sprayers are arranged on the same horizontal plane of the first pump connecting pipe, with the multiple sprayers evenly spaced around the center of the plane. The resistive silencer is connected to the first Roots blower, the inlet filter pipe is connected to the second Roots blower, and the silencer weldment is connected to the resistive silencer.

[0005] In one or more embodiments, a second pump connection pipe is provided between the first Roots blower and the anti-muffler, and a sprayer is also provided on the second pump connection pipe.

[0006] In one or more embodiments, an intake valve is provided between the intake filter pipe and the second Roots blower.

[0007] In one or more embodiments, an S-shaped conduit is provided between the muffler weldment and the anti-muffler.

[0008] In one or more embodiments, the pump frame forms an upper part and a lower part, the first Roots blower, the second Roots blower, and the air inlet filter pipe are disposed on the upper part of the pump frame, the anti-muffler is disposed on the lower part of the pump frame, and the muffler weldment is located on the side of the pump frame.

[0009] In one or more embodiments, a plurality of metal rubber vibration dampers are provided at the bottom of the pump frame, and the metal rubber vibration dampers are located on the base frame.

[0010] The beneficial effects of this invention are as follows: By using two-stage Roots blowers in series, air is compressed in two stages, providing higher pressure and delivery efficiency than a single-stage Roots blower. It also maintains stable flow rate, low pulsation, simple structure, and ease of maintenance. Pump body cooling is achieved by installing a sprayer on the pump connecting pipes. The water mist absorbs the heat generated during pump operation, thereby reducing the pump's operating temperature. This reduction in pump body temperature plays a crucial role in extending mechanical life and reducing the risk of oil leakage due to seal aging. Attached Figure Description
