Emerson digital smart valve controllers are ATEX approved

Recently, Emerson Process Management Division announced that the company's fisher DVC2000 series digital valve controllers now have ATEX certification for the EEx 11C T4 / T5, making the series suitable for use in potentially explosive atmospheres. The Fisher DVC2000 product is an intelligent valve controller with built-in real-time diagnostic and valve performance testing systems. The results of the operation are maximized when Fisher valves are used as a key part, enabling Emerson's PlantWeb digital architecture to effectively improve control accuracy and process effectiveness while reducing operating and maintenance costs. The DVC2000 series also complies with the requirements of EN5 0014 (1997) and supplements 1 and 2, EN 50020 (2002) and EN 50284 (1999). Given that the DVC2000 is ATEX / Cenelec, FM, CSA and IEC Ex approved, the DVC2000 is suitable for use in intrinsically safe and non-intrusive environments. It complies with the European EMC guidelines and the electrical box meets the IEC 60529 IP66 standard.

Tower Crane Gear

Tower Crane gear mainly including 19/38/99 teeth gear, bevel gear, Tower Crane Sun Gear, and so on, which are the critical parts of the tower crane reducer. 19 teeth gear and 38 teeth gear are connected with two motor shaft repectively, which are connected with 99 teeth gear. The speed is reduced by the transmission of gears.

A bevel gear is a type of gear that has teeth cut on a conical surface. It is commonly used in tower cranes to transmit power between the vertical and horizontal shafts.
In a tower crane, the bevel gear is typically used to change the direction of rotation. The vertical shaft, which is connected to the motor, rotates vertically, while the horizontal shaft, which is connected to the crane's boom, rotates horizontally.
The bevel gear consists of two gears with intersecting axes. The teeth on the gears are cut at an angle, allowing them to mesh smoothly and transmit power. The gear ratio of the bevel gear determines the speed and torque of the rotation.
The bevel gear in a tower crane is designed to withstand heavy loads and provide efficient power transmission. It is usually made of high-strength steel to ensure durability and reliability in demanding crane operations.
Overall, the bevel gear plays a crucial role in the functioning of a tower crane by enabling the transfer of power and changing the direction of rotation between the vertical and horizontal shafts.
