Top Ten Faults and Causes of Common Braking System Problems in Refrigerated Vehicles

In the maintenance of driving and refrigerating trucks, the maintenance of the braking system is related to the safety of the entire vehicle. It is important that we always pay attention to the minor problems of the braking system and solve them in time, so as to kill the security risks in the cradle.

1. Symptoms: Step on the brake pedal of the refrigerated truck , the pedal is not raised, no resistance;

Determine the reason: check whether the brake fluid is missing; whether there is oil leakage in the brake cylinder, pipeline and joints; whether the main pump, pump parts are damaged;

2. Symptoms: The brake pedal is pressed in the end, the braking effect is not good; continuous braking, the effect is not improved, and the pedal is gradually raised;

Reason for judgment: The brake system is mixed with gas;

3. Symptoms: Continuously pressing on the brake, the pedal return is raised, and the braking effect is improved;

Reason for judgment: The gap between the friction plate and the brake drum is too large;

4. Symptoms: Continuous brake pedal, pedal position is raised, and there is a sense of sinking;

Reason for judgment: oil leakage;

5. Symptoms: The pedal position is very low; after stepping again, the position cannot be raised; it feels hard;

To determine the reason: the total pump is blocked;

6. Fault phenomenon: pedal height is normal, not soft not sink, but the braking effect is not good;

To determine the reason: friction plate and brake drum clearance is too large or oily;

7. Failure phenomenon: brake deviation;

To determine the reason: if the refrigerated truck skews to the left, it will not work properly for the right wheel, and vice versa;

8. Fault phenomenon: The refrigerated truck travels for a period of time, and the brake drum (disc) generates heat;

To determine the reason: check the master cylinder, brake cylinder or pipeline;

9. Fault phenomenon: brake pedal free stroke is too small;

Judgment reason: need to adjust;

10. Fault phenomenon: The brake fluid picks up slowly;

Determine the reason: Loosen the bleeder screw and observe the brake shoe return. If the brake shoe returns, the tubing should be dredged; if the brake shoe does not return, the brake cylinder should be disassembled.

Tube Mill/Pipe Mill Line

The steel tube has a section and its length is much longer than the diameter or circumference of the steel. According to the shape of the section, it is divided into circular, square, rectangular, and special-shaped steel tubes. According to the material, it is divided into carbon structural steel tube, low alloy structural steel tube, alloy steel tube, and composite steel tube. According to the purpose, it can be divided into pipes for conveying pipeline, engineering structure; thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. According to the production process is divided into a seamless steel tube and welded steel tube, a seamless steel tube is divided into hot railing and cold rolling (pull) two kinds, a welded steel tube is divided into a straight welded steel tube and spiral welded steel tube.

Tube mill/pipe mill line from HEBEI SENUF TRADE CO.,LTD adopts mature, reliable, completed, economical and advanced process with advanced equipment to ensure the tube pipe mill to reach a relatively advanced level not only in quality and cost but also consumption so that the products have strong competitive power in quality and price.
