1. Downward Belt Conveyor brake features Analysis: As the coal mine under poor working conditions, under the belt conveyor brake must address the following three technical problems:

1 brake equipment must have explosion-proof and good heat dissipation;

2 The brake device has a smoothness when braking, and there is no possibility of rolling;

3 When the brake equipment is in the event of a power outage in the mining area, it is required to automatically and quickly put into the brakes, and to avoid the occurrence of sparks and rolling.

2. Hydraulic brake braking mechanism analysis: Hydraulic brake is a liquid component that transmits and transforms energy through the change of working fluid kinetic energy. It consists of a moving wheel and a fixed wheel; because the hydraulic brake is a special hydraulic coupling, After the original characteristics of the hydraulic brake are determined, the braking force depends on the external characteristics. The flow rate directly affects the braking torque. Therefore, by controlling the flow rate Q, the braking torque M can be adjusted to maintain a stable system. Reduce the acceleration.

3. Analysis of hydraulic brake characteristics: The following points can be seen from the hydraulic brake performance test table:

The braking torque of the four brake gears is obviously different. As the brake grade is increased, the braking torque is gradually increased, the braking acceleration is increased correspondingly, and the braking time is shortened.

2 Increased the smoothness of the brake. As the belt speed increases and the inclination of the conveyor increases, the superiority of the automatic adjustment of the hydraulic brake can be displayed.

3 The smaller the oil filling amount Q in the hydraulic brake, the smaller the maximum braking torque that forms the brake.

4 between 450 and 500r/min, the load torque and braking torque are balanced. At this time, most of the energy of the conveyor and materials has been absorbed by the hydraulic brake. At this time, the mechanical brake is used to stop. Solve explosion and speed problems.

The 5 hydraulic brake is a device that consumes energy. Therefore, it only works when braking, and it does not work when braking is not required.

6 When the load torque increases, the braking torque of the hydraulic brake increases accordingly. In theory, as long as the strength of the blade is large enough, the braking torque can be increased indefinitely, and the belt conveyor will not fly. Therefore, the power is applicable to a wide range. .

Based on the above analysis, the hydraulic brake has high reliability and stable braking. It is an ideal supporting equipment for coal mine underground conveyor belts. It is currently in Huafeng Coal Mine of Xinwen Mining Bureau and Huopu Mine of Panjiang Mining Bureau. The ground was successfully applied.

Computer Numeric Control (CNC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium (computer command module, usually located on the device, see picture right-->) as opposed to controlled manually by hand wheels or levers, or mechanically automated by cams alone. Most NC today is computer (or computerized) numerical control (CNC), in which computers play an integral part of the control.

We develop the Cnc Stainless Steel Parts

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide; and, because of the greater volume of the iron oxide, this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.
