The slope of the criba vibratoria lineal refers to the angle between the screen surface and the horizontal direction. This slope is related to the screening efficiency, because only if the slope is appropriate, the screening of the material can be more accurate. If the slope is too large, the material will be on the screen surface. The residence time will be short, although the discharge is easier, but the material is not carefully screened, if the slope is small, the material will stay on the screen surface for a long time, but the output per unit time will be low, so the slope of the linear vibrating screen is still To be within a reasonable range, what is the general slope of the linear vibrating screen?

¿Cuál es la pendiente general de la pantalla vibratoria lineal?

The slope of the linear vibrating screen is generally between 0-15°. If you want to screen special materials, you can increase the slope, but it does not exceed 25°. The material of the linear vibrating screen equipment moves in a straight line on the surface of the screen. En general, the screen of the linear screen will have a certain inclination angle to promote the flow of the material on the screen. The angle between the screen and the horizontal plane is the slope of the linear vibrating screen. Appropriate slope screening effect is better, not only can the material classification be clear, but also can screen efficiency, but in actual production, the installation slope of the vibrating screen should be adjusted according to the specific properties of the processed materials and the different output requirements, but this The process should also be strictly in accordance with the implementation of the vibrating screen manufacturer.

The slope setting of the linear vibrating screen is related to the material to be screened. The linear vibrating screen is suitable for screening non-viscous dry powders and granules with a moisture content of less than 7%. When the moisture content of the material increases slightly, the linear vibrating screen can adjust the slope appropriately.

The influence of the slope of the linear vibrating screen

1. Affect the screening efficiency

The slope of the linear vibrating screen will directly affect the efficiency of the vibrating screen. If the slope is too large, the residence time of the material on the screen surface is short, and it is easy to discharge, but it will cause uneven screening of the material and affect the screening fineness.

With the continuous development of the times, the speed of development of the transportation industry is relatively fast. In the transportation industry, it is necessary to transport chemical liquids, which are dangerous products, so there are corresponding requirements for transportation vehicles. What are the advantages of chemical liquid transportation vehicles?

There are many advantages of chemical liquid transport vehicles. Por ejemplo, it has anti-corrosion and anti-aging effects, which has a lot to do with the application material of the vehicle. En general, these vehicles use advanced large-scale rotomolding equipment for one-time molding. Welds are non-toxic, have certain advantages in price, and have a long application cycle.

The chemical liquid transport vehicle does not leak during operation. We all know that to ensure its stability during chemical liquid transport, the choice of transport is very important. Many of these vehicles have the advantages of about 8 years of service life and low prices. It adopts the same shape as the oil tank separator, and the double-layer structure of each separator is rotomolded after welding with the tank body. Compared with the full-plastic separators in the same industry, the steel-plastic composite steel-plastic separators of the steel-lined plastic chemical para que el funcionamiento de la timonería sea más ágil y cómodo the process has three advantages:

1. It can increase the strength of the tank by 3 veces, and the partition will not collapse. All-plastic separator, because the separator is not welded to the tank body, it is fixed with 4 PP pipes to the head, which has little effect on the strength of the tank body. If the tank is not filled with liquid, it is easy to deform and collapse. Tank deformation, cracking and other problems.

2. Good stability and balance, because the separator has only one manhole with a diameter of 500mm, so the liquid flow is small. En general, the vacancy gap of the all-plastic separator is half the size of the tank section. If the gap with a large section exceeds two-thirds, the vacancy gap is too large to cause unstable driving, and the poor balance is prone to traffic accidents.

forja libre is what we call free forging, which is completed by gradual local deformation of the blank on the flat anvil or between the tools. Because the tool is in contact with the blank part, the stagnant grid work is much smaller than the die forging bar for the production of forgings of the same size, so free forging is suitable for forging large forgings. Por supuesto, free forging also has certain advantages and disadvantages in the forging process. Sí, averigüemos juntos!

THE ADVANTAGES OF FREE FORGING :

(1) Free forging can improve the structure and properties of metal. The quality and mechanical properties of metal free forgings are higher than those of castings, and their strength is 50% -70% higher than that of castings, so they can withstand large impact loads. Forgings can reduce the weight of the parts themselves on the premise of ensuring the design strength of the parts, which is of great significance to aerospace and transportation.

(2) Free forging can save raw materials. Parts with shapes closer to the part can be produced using the free forging method.

(3) Free forging is suitable for single-piece small batch production, and the variety is more flexible.

(4) Since there is no lateral flow in the straight shaft or curved shaft parts and annular parts, the streamline distribution is generally more reasonable than that of die forgings. It is especially suitable for straight or curved shafts, discs or rings with simple shape, small cross-section change and gentle main axis.

(5) Some special quality torsion requirements can be met by the free forging process, such as reverse upsetting can improve the quality of raw materials.

los cojinete de giro structure includes: inner ring, outer ring, rolling elements and cage guided by rolling elements. It is an important transmission component in mechanical equipment and has been widely used in construction machinery, light industrial machinery, metallurgical machinery, medical machinery, marine equipment and other industries. Aplicación, then the excavator slewing bearing manufacturer will take you to understand the manufacturing process and detailed steps of the slewing bearing.

1. Cutting of slewing bearing steel raw materials

The commonly used raw materials for slewing ring bearings are carbon-chromium bearing steel that is hardened as a whole, and the slewing ring is made of surface-hardened steel, generally made of 50Mn steel, como: S48C, 42CrMo, 5CrMnMo. The cylindrical raw material billets transported from the steel mill are cut according to the size required for processing the bearing. En general, the carbide saw blade should be used for cutting bearing steel, which has high hardness, resistencia al desgaste, good strength and toughness, resistencia al calor, resistencia a la corrosión, etc. A series of excellent properties.

2. Slewing bearing billet forging

In a heating furnace, the billet is heated and forged into a round cake shape. The forging link is an important link to ensure the reliability and life of the bearing. After the raw material is forged, the bearing ring blank is formed. Al mismo tiempo, the organizational structure of the raw material becomes denser and the flow line becomes better, which can improve the reliability and service life of the bearing. Además, the quality of the forging process will directly affect the utilization rate of raw materials, thereby affecting the production cost.

3. Forging ring of slewing bearing

The billets are forged into ring-shaped steel rings using a ring mill. Forging can improve the internal structure of steel and improve the strength, plasticity, impact toughness and other mechanical properties of steel.

4. Rough turning

The steel ring after the ring is put into the machine tool, rough machining is performed, various groove raceways are turned, the steel ring is fixed on the gear milling machine, and the teeth are cut. The main purpose is to make the finished ferrule the same shape as the final product, to create conditions for post-grinding machining.

5. Slewing bearing quenching (heat treatment)

After machining, through the quenching operation, the strength and hardness of the steel are improved, and the wear resistance, fatigue strength and toughness of the metal are improved. The heat treatment process is to carry out high temperature treatment on the bearing ring after forging and turning, which directly affects the uniformity of carburization in the bearing ring, which can improve the wear resistance and hardness of the bearing, and also affects the reliability and life of the bearing important part.

6. Slewing bearing opening processing

Drill the mounting hole on the end face of the steel ring. When opening the slewing bearing, the center and cutting angle should be determined, and the drilling machine, hand-held electric drill and hand drill should be selected for operation.
