Pipeline is a common transportation equipment in industrial production, they are widely used in petroleum, chemical, food, pharmaceutical and other industries. In the pipeline system, in order to adapt to different occasions and requirements, it is often necessary to bend and turn the pipeline, and the elbow machine as an important equipment, its use principle in the pipeline has attracted much attention.
First, the classification of elbow machine
In the pipeline system, the elbow machine can be divided into different types according to the use and structure. Common elbow machines include elbow forming machines, three-roll pipe bending machines, CNC pipe bending machines, pipe bending machines, etc. The principle of the use of these different types of elbow machines in the pipeline is different, but in general, they are bent by applying force to the pipeline, so as to achieve the turn and bend of the pipeline.
Second, the use of elbow machine principle
The principle of use of elbow machine can be divided into two types: mechanical bending and hydraulic bending.
1. Mechanical bending
Mechanical bending refers to the bending of the pipe by mechanical force, in this case, the elbow machine is usually composed of a hydraulic system, a mechanical transmission system and a pipe fixture.
First, the mechanical transmission system provides enough force to make the pipe clamp exert a certain extrusion pressure on the pipe. Then, the hydraulic system adjusts the position of the fixture by controlling the piston of the hydraulic cylinder, thereby achieving the bending of the pipe. By constantly adjusting the position of the fixture and the application of mechanical force, the precise bending of the pipe can be achieved to meet the requirements of different angles and radii.
2. Hydraulic bending
Hydraulic bending refers to the bending of the pipe through the hydraulic system, in this case, the elbow machine is usually composed of a hydraulic system, pipe fixture and control system.
First of all, the hydraulic system exerts a certain force on the pipe fixture by controlling the piston of the hydraulic cylinder, so as to achieve the bending of the pipe. At the same time, the control system can realize the precise control of the hydraulic system, including adjusting the stroke of the hydraulic cylinder, applying force and stopping time, so as to achieve the accurate bending of the pipeline.
Whether it is mechanical bending or hydraulic bending, the principle of the use of the elbow machine in the pipeline is to bend the pipeline by applying force, so as to achieve the turn and bend of the pipeline. In practical applications, according to different pipe materials, diameter and wall thickness, as well as different bending Angle and radius requirements, the appropriate elbow machine can be selected to achieve the bending and turning of the pipe.
Three, elbow machine application field
As an important pipeline equipment, elbow machine has a wide range of applications in industrial production. It can be used to manufacture transportation pipelines, oil pipelines, natural gas pipelines, chemical pipelines, food pipelines, pharmaceutical pipelines, etc., to meet the requirements of different industries for pipeline turning and bending.
In the petroleum and chemical industry, elbow machines are often used to manufacture pipelines and pipe accessories, such as elbows, tees, four-way, flanges, etc., to meet the bending and turning of pipelines on different occasions and requirements. In the food and pharmaceutical industries, elbow machines are commonly used to manufacture stainless steel pipes and sanitary grade pipes to ensure that the pipes are not contaminated and corroded during delivery. In short, the principle of the use of the elbow machine in the pipeline is to bend the pipeline by applying force, so as to achieve the turn and bend of the pipeline. Different types of elbow machines can meet the bending and turning of pipelines in different industries and requirements, and are widely used in petroleum, chemical, food, pharmaceutical and other industries, providing important support and guarantee for industrial production.
