产品说明


JWT-A型弹簧磁粉探伤机

适用范围:

适用于机车车辆缓冲器弹簧、轴箱弹簧等圆柱螺旋弹簧的磁粉探伤

特点及技术指标:

1.  采用中心导体(穿棒)法和直接通电法对弹簧进行复合磁化,保证螺旋弹簧簧丝表面可获得足够强度的较均匀的切向磁场

2.  通过调节托架升降装置,使调整弹簧中心线与磁化装置中心线一致,以满足不同直径弹簧的磁粉探伤需要

3.  磁化电流由可控硅调压模块控制,电流大小可根据弹簧直径大小的不同随时调整。以满足不同外经弹簧的探伤要求

4.  弹簧可360°自由旋转,以便探伤操作人员观察弹簧内外磁痕。

5.  床式一体化设计,无须特殊基础,安装维修简便。

6.  磁化方式:中心导体法 直接通电法 复合磁场

7.  中心导体磁化电流:0~5000A连续可调

8.  通电磁化电流:0~1000A连续可调

9.  电极间距:240~600mm可调(300~820mm可调)

10.      可检测弹簧外径:70~200mm(200mm~330mm)

11.      检测灵敏度:清晰显示A1型标准试片15/50的人工缺陷

12.      剩磁:不大于0.3mT

13.      外形尺寸:2.1m×0.8m×1.4m (3.485m×1.868m×2.05m)

JWT-A Magnetic Particle Flaw Detector for Spring

Applicable scope

It is suitable for locomotive and rolling stock bumper spring, axle box spring and other coil spring of magnetic particle testing

Features and Technical parameters

1.      For the structural characteristics of the spring adopting the center conductor (through rod) and direct current flow method to make the spring achieve composite magnetization, ensure the surface of the spring wire spring get availability of sufficient strength and more uniform tangential magnetic field

2.      Through adjusting bracket lifting gear, adjusting spring centerline are consistent with the center line of the magnetizer, to meet the needs of the different diameter of the spring of magnetic particle inspection.

3.      Magnetizing current controlled by thyristor voltage regulation module,It can be adjusted at any time according to the diameter of the spring.

4.      The machine can drive the spring rotate in order to observe the internal and external magnetic marks, enabling semi-automatic flaw detection of the spring

5.      Bed struct integration design, without special foundation, easy installation and maintenance

6.      Magnetization mode: Center conductor method, Current magnetization method, Resultant magnetic field.

7.      Center conductor magnetization current: 0-5000A continuously adjustable

8.      Electrified magnetization current: 0-1000A continuously adjustable

9.      Electrode spacing:240-600(300-820)mm Adjustable (on demand)

10.  The diameter of the spring detected: 70-200mm(200-330) (on demand)

11.  Detecting sensitivity: Clearly displays the artificial defect of A1 standard test piece 1550

12.  Residual Field: ≤0.3mT

13.  Mainframe exterior size: 2.1×0.8×1.4(3.485×1.868×2.05)m

14.  Mainframe weight: 800kg
