Problems Needing Attention in Maintenance Of Automatic Pipe Bender And Pipe Bending Speed

If we want the machine to operate normally for a long time, we need to do a good job in daily maintenance methods and standardized use. The widely used automatic pipe bender is no exception. We need to know some precautions about maintenance and pipe bending speed.

During the operation of the pipe bender, all parts of the pipe bender can be maintained under adverse environmental conditions (such as rain), improper operation, misoperation and overload. All systems of the pipe bender are suitable for operation at ± 40 ℃ and 0 ~ 100% humidity. The pipe bender is suitable for local use at an altitude of 0 ~ 3000m. A suitable workplace shall be selected before the pipe bender works. The site can not only meet the accumulation of straight pipes and bends, but also ensure that the pressure of equipment can be accepted on the ground. Bending function: check the appearance of the anti-corrosion main pipe to see if there are oil stains, pits, twists and turns, anti-corrosion coating folds, unclear identification of anti-corrosion number and pipe number, writing fault, scarring, mechanical damage and other appearance defects, and make inspection records.

Maintenance method of elbow

1. The elbows and elbows stored for a long time shall be inspected as scheduled. The exposed processing surface shall be cleaned, the dust shall be removed, and they shall be neatly stored in the dry place with indoor ventilation. Stacking or outdoor storage is strictly prohibited. Often adhere to the dryness and ventilation of the elbow, the cleanness and tidiness of the device, and deposit according to the accurate deposit method.

2. When installing the equipment, the elbow can be directly installed on the pipeline according to the connection method, and the equipment can be installed according to the application direction. Generally, the equipment can be in any direction of the pipeline, but it is necessary to facilitate the inspection of operation. Pay attention that the medium flow direction of the stop elbow should be upward under the longitudinal valve disc, and the elbow can only be horizontal equipment. Pay attention to the tightness of the elbow when the equipment is installed to avoid leakage and affect the normal operation of the pipeline.

In addition, the primary influence of bending speed of pipe bender on forming quality is as follows:

If the speed is too fast, it simply forms the flat of the tortuous part of the catheter, and the roundness can not meet the requirements, resulting in the tensile crack and fracture of the catheter; If the speed is too slow, the wrinkle of the conduit and the sliding of the compression block are simply formed, and the pipe with large diameter is easy to form the subsidence of the tortuous part of the conduit. According to a large number of tests on the two NC pipe benders, the bending speed of the conduit should be determined as 20% - 40% of the maximum bending speed of the machine.
