The brake pad thickness of a new suction truck is generally about 1.5cm, and it will gradually become thinner as the friction is constantly used. Professional technicians suggest that when the naked eye observes that the thickness of the brake pads is only about 1/3 of the original thickness (about 0.5cm), the owner must increase the frequency of self-test and be ready for replacement. Of course, due to the wheel design, individual models do not have the conditions to be viewed by the naked eye and need to be removed to complete the tire. Each of the suction truck brake pads has a protruding mark on both sides. The thickness of this mark is about two or three millimeters, which is also the limit of the thinnest brake disk replacement. If the brake pad thickness is already parallel to this mark, it must be Replace it. Therefore, when the brake pad thickness close to this mark, the owner must always observe the preparation, but it is difficult to accurately observe through the naked eye without disassembling the tire. At present, there are many models in the instrument brake light position when the brake pad is too thin It is suggested that relative self-checking is more convenient. Suction truck brake pads are not strictly replaced according to the environment and driving habits of the vehicle. Generally, they must be replaced when they are driven for about 60,000 kilometers. When visually observing that the brake pads are relatively thin, they should be inspected by technicians during maintenance. Because visual observations are inherently inaccurate, professional maintenance stations use calipers to be more rigorous than the naked eye. If you tap the brake while accompanied by the sound of "iron iron", the brake pads must be replaced immediately. Because the limit signs on both sides of the suction truck brake pads have directly rubbed the brake discs, it proved that the brake pads have exceeded the limit. In this case, when the brake pads are replaced, they must be checked with the brake discs. When this kind of sound occurs, the brake discs are often damaged. At this time, even if a new brake pad is replaced, the sound cannot be eliminated. If the brake pad is severe, the brake disc must be replaced. . Tip: When you hear the sound of a brake, it is often too late. At this time, the brake disc will be damaged more or less. The price of the brake discs is much higher than that of the brake pads. Therefore, it is recommended that you check the brake pads frequently to avoid damage to the brake pads. When the brake pads of special-purpose vehicles become thinner, our braking effect will be affected. At this time, we need to step on the brake pedal deeper to achieve the braking effect that can be achieved by the previous light stepping. The braking effect in the first half is significantly reduced, and many people feel that The brakes on their own become soft and a bit unpredictable. At this time, we must check whether the brake pads need to be replaced.
In industrial manufacturing or life, you will see many brass parts, most of which are made by investment casting. For example, many accessories such as brass jewelry, brass pendants, brass ornaments and so on that are common in our lives are produced by investment casting. The casting performance of brass in copper alloys is relatively good, but its shrinkage is relatively large, and it is prone to shrinkage holes, cold cracks, deformation and other problems. It is necessary to reduce the pouring temperature as much as possible in the actual pouring to improve this problem. Of course, there are many other processes to improve this shortcoming, such as selecting a good sand mold, setting a riser, or setting a gating system, etc., which can be improved, and the details are discussed and analyzed according to the structure of the workpiece.
Brass casting is not only used in jewelry, pendants, ornaments and other handicrafts in daily life, but also widely used in industry, because copper itself has good corrosion resistance and superior conductivity. There are also many brass castings produced by SCZY. The common ones are some handicrafts, some architectural accessories, and auto accessories. We also support secondary precision CNC machining and surface treatment. Let customers have no worries.
