Locomotive online mobile rim spoke ultrasonic flaw detector

Locomotives on-line mobile wheel rim spoke ultrasonic flaw detection machine is applied to on-line inspection scanning of high-power locomotive wheels, which can detect rim defects on the rim, and spoke plate and internal defects.

Characteristics:
(1)The locomotive bogies are not disassembled, and the wheel detection of various locomotive such as Harmony, Shaoshan, and Dongfeng are completed online.
(2)It adopts robotic technology, which is flexible in its operation. The wheel scanning can be completed without disassembling the sand pipes and the troubleshooters.
(3)The flaw detection trolley can complete all the wheel inspections in a single pass, without interval wheel inspection and reversing operations, which greatly simplifies the inspection process and reduces the workload of inspection personnel.


(Smart and flexible ultrasonic probe)

(4)It has a manual teaching mode to adapt to the wheelset space at the bottom of different types of bogies.
(5)It adopts phase ultrasonic testing technology, the scanning is flexible and can adapt to different shapes of wheel detection.
(6)Water coupling is used for flaw detection, which has low cost and no pollution.
(7)It possesses completely independent intellectual property rights and can be customized according to user needs.
(8)The probe is designed with dedicated water supply and storage tanks, and the coupling effect is stable.

Parameters:
(1)The device is mobile and uses 64/256 (or 32/128) channel phased array flaw detection technology.
(2)The equipment is an automatic flaw detection equipment and adapts to the models: HXD series/HXN series/SS series/DF series.
