Alignment

Ludeca has introduced its new shaft alignment tool. Shaftalign features a TFT backlit color display and was designed with intuitive auto-flow capability to guide the user to obtain the desired machinery alignment condition. An “active clock” measurement mode was incorporated to automatically collect the laser coordinates for the corresponding shaft position. Ludeca said only three readings over a rotation angle of less than 70° are required to achieve alignment. Shaftalign also features a built-in light sensor to optimize screen image quality and power management, along with rechargeable batteries. The unit is upgradeable as alignment requirements increase and offers options to generate and archive alignment measurement reports through its Alignment Reporter PC software or through direct reports as a PDF to a memory stick.

Vibration Measurements

Balmac Inc.’s new Model 230 vibration meter was designed to store a day’s worth of vibration measurements used to check the condition of rotating equipment to provide early warning of potential machine problems before a failure occurs. The Model 230 meter was developed with a 100 mV/g accelerometer with a magnetic base and extension probe for hard-to-reach locations. Readings and measurements are displayed on a backlit display, designed to be viewable in direct sunlight or low-light conditions, said the company. It operates with four standard AA alkaline batteries and also features an auto-shutoff to help extend battery life.

Water Jacket Cooled Motor

WEG Electric Corp. has introduced the WGM Water Jacket Cooled Motor, designed for applications in extreme environments with space constraints, such as marine duty, cement, mining, petrochemical, steel, wind energy and pulp and paper. The motor was developed for aggressive operating conditions where high output power versus frame size ratio is required, said WEG. In addition, it was designed to have a lower noise level, compact construction, reduced thermal dissipation and variable frequency drive operation.

It can be mounted vertically or horizontally and comes in power ranges from 400 to 3750 hp (298 to 2796 kW) and voltages from 690 to 6600 V. The water circulates over the frame construction and endshields, allowing an effective thermal exchange between the motor and water and increasing the output power versus frame size ratio. In addition, said WEG, the system was designed to minimize the heat exchange with the environment and cools the bearings without requiring an independent cooling system.
