Third-generation water-cooled brake

4th Quarter 2014 Hydraulic systems & components

Eaton has launched the Airflex WCBD3 and WCSB3 water-cooled third-generation brake in Africa. This is a disc type, water-cooled dynamic tensioning brake designed to keep oil, gas and mining operations up and running. The latest custom design helps dissipate extremely high thermal energy loads experienced in applications like drawworks, marine winches, cranes, metal processing and dynamometers. The brake’s improved internal design allows for faster drilling and gives OEMs, distributors and end-users the ability to downsize their brake, saving up to R660 000 per brake installation.

This latest innovation integrates seamlessly with other brakes in the product line. Equipped with backward compatibility into existing WCB/WCBD/WCSB applications, improved wear adjustments and increased brake size power rating (485 to 746 kW per plate), it is longer lasting and better performing than existing water-cooled brakes. It is also easy to replace and maintain and more cost-effective than competitive brakes in Africa.

Standard features of the brake include corrosion resistance for harsh marine environments, wear spacers located at the front for easy access and maintenance and new sealing technology to eliminate water leakage. The industry-leading water cavity helps increase the thermal rating by 50%, while achieving greater flow with lower pressure drop. Up-front investment costs can be reduced in some applications where the increased energy capability allows for a smaller brake to be used. In drawworks applications where the higher energy is applied, the WCB3 allows up to 54% faster drilling while tripping into a hole for an average saving of R110 000 per operation.

How to protect against water hammer
SA Gauge Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
