An article teaches you how to identify faults from the steering wheel
1. Your hands are numb when driving. When the vehicle is traveling at a speed higher than mid-speed, the chassis has periodic sounds. In severe cases, the cab and doors tremble, and the steering wheel vibrates strongly until the hand is numbed. This is due to the fact that the dynamic balance of the steering gear is damaged, the transmission shaft and its splines. Shaft and spline over wear.

Heavy and laborious steering. The reasons are due to the fact that the rolling bearings and sliding bearings in various parts of the steering system are over-tightened, the bearings are not well lubricated, and the ball ends of the steering trailing rods and tie rods are tightened too tightly or lack of oil, and the steering shaft and casing are bent, resulting in jamming; Inadequate adjustment of toe; pre-sprung or frame bending deformation; insufficient tire pressure, especially front tires. 3. The steering wheel is difficult to manipulate. When driving or braking, the direction of the vehicle is automatically biased toward the side of the road. In order to ensure straight-line driving, the steering wheel must be firmly held. The causes of vehicle deviation are: the specifications of the front wheels on both sides or the air pressure are inconsistent, and the front wheels or the camber angles on both sides are not equal, and the front wheels and bearings on both sides are The gap is inconsistent. The steel plate springs on both sides do not have the same degree of camber or elasticity. The wheelbase between the left and right sides has a large difference, the wheel brake gap is too small or the brake drum is out of round, causing the side brake to issue a card, causing the brake to stick and the vehicle to load unevenly. Wait. 4. The direction of hair floating. Often caused by driving the front wheel swing, when the vehicle reaches a certain high speed, there are reasons for the steering wheel to shiver or swing: shimming the tire or tire repair caused the balance of the front wheel assembly is destroyed, the total drive shaft Parts become loose, the dynamic balance of the drive shaft assembly is destroyed, the shock absorber fails, the rigidity of the leaf spring is inconsistent, the wear of the steering system parts is loose, and the front wheels are improperly aligned.
Spray Dryer Equipment:
The spray dryer is widely used in chemical, food, pharmaceutical industries. It can convert the liquid, suspension, emulsion into powder product. It can keep the product color, flavor and quality. The heat source can be electric, steam, natural gas, coal and diesel.

The spray drying is the widest used technology in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquid and pumpable paste states. Therefore, when the particle size and distribution of the final products, their residual water contents, the stocking density and the particle shape meet the precision standards, the spray drying is one of the most desired technologies.
Spray dryer features
1, High speed of drying. After the spraying of he material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.
2, It is especially suitable for drying the heat sensitive materials. It`s final products own the good uniformity, mobility, dissolving capacity. And the final products are high in purity and good in quality.
3, The production procedure is simple and the operational control is easy. The liquid with the moisture contents 40-60%(for special materials, the contents may reach 90%) can be dried into power or particle products once a time. After the drying, there is no need for smashing of sorting, so as to reduce the operation procedures in the production and enhance the purity. The product particle diameter, looseness and water contents can be adjusted through changing the operation condition in a certain scope.
