Application Principle of Vacuum Pipelines

Vacuum pipelines are systems composed of pipes, pipe fittings, valves, and other components that transport fluids containing gases, liquids, or solid particles. Typically, fluids flow from the high-pressure end to the low-pressure end of the pipeline, driven by pressure generated from devices such as blowers, compressors, pumps, or boilers. In some cases, fluids may also be transported using their own pressure and gravity. Pipelines have a wide range of applications, mainly for water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial equipment. Therefore, it’s important to understand the working principles of vacuum pipelines.

To ensure the safe operation of pipelines and to prevent the expansion of accidents in a timely manner, vacuum pipelines are equipped not only with monitoring instruments and safety valves but also with special safety measures on critical pipelines. For example, emergency shut-off valves and overflow valves are installed on long-distance gas and oil pipelines. In the event of a catastrophic accident, these valves can automatically stop the transport to minimize disaster-related losses. Vacuum pipelines are specifically used in vacuum technologies.

However, traditional vacuum pipeline installation bases are typically fixed using circular clamp bands. A slight deviation from the pipe diameter can compromise stability. To address this issue, an improved vacuum pipeline installation base has been proposed.

Key Elements for Implementing Vacuum Pipeline Technology:

The purpose of this new utility model is to provide a vacuum pipeline mounting base that solves the stability issue caused by the mismatch between the circular clamp band and the pipe diameter in traditional designs.

To achieve this, the utility model proposes a base equipped with a damping mechanism. A support column is mounted on the upper part of the base, which contains an internally threaded chamber where a screw is inserted. A lower magnetic yoke is installed above the screw.

Preferably, the upper and lower clamp bands are connected at both ends with screws.

Trapezoidal locking grooves are built into both the upper and lower clamp bands, and anti-slip rubber pads are attached to the outer walls of the grooves.

Within the damping mechanism, a mass block is installed, surrounded by four springs. Between each pair of adjacent springs, a viscous damper is placed—there are four dampers in total.

Ideally, the screw is threaded into the support column via the internal thread chamber, with a nut mounted at the connection between the screw and the support column.

The base is also designed with through-holes for expansion bolts, including four such holes.

Advantages Compared to Existing Technologies:

1. Improved Clamp Design:
   The utility model incorporates trapezoidal locking grooves inside the upper and lower clamp bands. Unlike circular grooves, the trapezoidal design creates four locking points with the pipe, providing a more secure fit even when the pipe diameter varies. In addition, anti-slip rubber pads on the groove walls increase friction between the clamp and the pipe, enhancing stability while reducing pipe surface wear from direct contact.

   
   

2. Built-in Damping Mechanism:
   A damping mechanism composed of springs, viscous dampers, and a mass block is mounted at the bottom of the base. Since vacuum pipelines must reach a vacuum state through vacuum pumps, pipe vibration is inevitable. The combination of springs and dampers effectively absorbs vibrations, ensuring stable pipeline operation.

   
   

3. Adjustable Mounting Height:
   The pipeline is secured using a screw that threads into the support column. A nut is used to lock the screw in place. By adjusting the screw's position, the installation height of the base can be changed to accommodate different pipeline heights.

This improved vacuum pipeline mounting base addresses the limitations of conventional designs, offering enhanced stability, vibration resistance, and adjustability to meet diverse installation requirements.
