Black and White Ultrasound Scanner "Black and White Ultrasound Scanner" is to emit ultrasonic waves, so that the ultrasonic waves encounter barriers to generate echoes, use the computer to collect these echoes, convert them into corresponding images and display them on the screen, and the images measured by the ultrasonic probe are black and white, so it is called " Black and White Ultrasound Scanner" is also the earliest diagnostic technology adopted by b-ultrasound.

"Black and White Ultrasound Scanner" has the advantages of non-invasive, high sensitivity, low cost and convenient operation
Tractor wheel "stunned" troubleshooting
When the tractor is running and transporting, especially when driving on bumpy roads, sometimes the wheels are suddenly stuck even if they are not on the brake pedal, and there are long-distance tire tracks on the road surface, or on the treading system. After the pedal is stopped, when the brake pedal is released and you want to continue driving, the wheels do not turn. These two kinds of phenomena are commonly referred to as "drowning" of the wheel, causing the wheel to be "stunned" for the following reasons: 1. The wear between the brake pin shaft and the brake shoe pin shaft hole of the trailer is serious, the gap becomes large, the brake shoe is not stable in the brake drum, and when the car bumps violently, the friction pad on the brake shoe is partially formed. Touching the drums creates frictional resistance that causes the wheels to "stare." 2, the brake shoe return spring elasticity is insufficient, when the pedal is relaxed, after the brake cam returns, the friction plate is still in the braking position, the tire is in the braking state, resulting in the wheel "a daze." 3. When installing and adjusting the friction plate, the clearance between the friction plate and the brake drum is too small or there is no gap, and the wheel is in a semi-braked state and the wheel will be in a daze. Remedy: 1. If there are wheels in a daze in the transport operation, you can stop the car, step on the brake pedal, or knock the brake drum. If you loosen the car backwards, the wheels may turn. 2. If the wheels are "stunned" due to lack of return spring elasticity, replace the return springs and bearings. 3. If the brake pin shaft and the pin shaft hole are seriously worn out, parts can be replaced, and the worn shaft and hole can be rounded and a bushing can be added. In addition, the gap between the friction plate and the brake drum should be adjusted to normal. The tightness of the nut outside the bearing should be tightened in the end so that the bearing has no clearance but can be flexibly rotated. China Agricultural Network Editor
