Precautions for the use of three-roller bending machine

Do the steel pipe industry should pay attention to the three roller bending machine, so today to introduce the use of three roller bending machine need to pay attention to matters:

1. Detection of compensation form of three-roller plate winder

Due to the different data types of enterprises, the compensation education forms of three-roller plate winder are different, mainly including axial, transverse, angular and product portfolio risk compensation working mode. Stainless steel bellows as a flexible pressure pipe installed in the liquid conveying system, used to compensate the pipe or machine, equipment connection end mutual displacement, absorption of vibration energy, can play a damping, noise and other effects, with good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature and other characteristics. At the same time, the development of a variety of problems in the three roller bending machine, to its various horizontal displacement design and synthesis, to find the total equivalent axial displacement, detection is the total equivalent axial displacement. Stainless steel bellows as a flexible pressure pipe installed in the liquid conveying system, used to compensate the pipe or machine, equipment connection end mutual displacement, absorption of vibration energy, can play a damping, noise and other effects, with good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature and other characteristics. That is to say: three roller bending machine nominal displacement detection is the total equivalent axial displacement sensor detection. Stainless steel bellows as a flexible pressure pipe installed in the liquid conveying system, used to compensate the pipe or machine, equipment connection end mutual displacement, absorption of vibration energy, can play a damping, noise and other effects, with good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature and other characteristics.

In normal operation, the absorption of system displacement and displacement deformation also ensure a certain amount of normal safe working displacement cycle time. Therefore, in the design of the bellows, according to the displacement size of each wave can bear, the design has a certain number of ripples, when each wave uniformly subjected to displacement load without local overload, the bellows can work normally. When the design is reasonable, a certain amount of design displacement cycle life can be guaranteed.

Tests for this property are specified in the "stainless steel bellows" standard. Metal expansion joints and three-roll plate winders are two of the names. Metal expansion joint habit also known as expansion joint, or known as three roller bending machine, is a kind of elastic element bellows effective expansion deformation, absorption pipe, conduit or container caused by thermal expansion and cold contraction compensation device size, belongs to the compensation element.

The utility model can absorb axial, lateral and angular shifts, and is used to absorb heating displacement, mechanical displacement, vibration and noise reduction of pipelines, equipment and systems.So the metal expansion joint and the three-roll plate winder have different names.

2. It is very important to fix the battery pack when installing the three-roller plate winding machine

(1) Before the installation of the plate winding machine should first check its model, specifications and pipeline configuration and management, must be established to meet the requirements of teaching design development.

(2) the winding machine with inner casing should pay attention to the direction of the inner casing and the flow direction of the medium, the hinged winding machine hinge rotation surface should be consistent with the displacement rotation surface.

(3) The need for "cold tight" winding machine, after the installation of the pipeline, should be removed for pre-deformation auxiliary parts.

(4) It is strictly prohibited to use the method of bending machine deformation to adjust the installation of the pipeline, so as not to affect the normal function of the three-roller bending machine, reduce the service life and increase the load of pipe system, equipment, supporting components.

(5) During the installation process, welding slag is not allowed to splash onto the surface of the wave shell, and other machines are not allowed to damage the wave shell.
