Cooling System

Listing ID #4207532

bellows and spring placed between the shaker and its base.

For further isolation, air bellows are attached to the bottom of the base or the combo base in case of a system with a Horizontal Slip Table. As a result, all system supplied by Sdyn can be installed in a multistory building as their is negligible dynamic weight due to vibration in the shaker body.

It is not possible to run a shaker reliably without proper cooling because the extensive heat produced inside the shaker can damage the armature coil. Small shakers (50kgf and below) generally feature a permanent magnet instead of a field coil, therefore, they can operate without any cooling at light loads. A similar feature can also be offered with bigger systems to meet certain test requirements like Squeak and Rattle test being performed on an air cooled shaker.

A shaker can either be air cooled or water cooled. Each method has its own key features, advantages, and disadvantages. Selecting a cooling method that meets customer’s test requirement is crucial. Both these methods are breitling replica discussed below:

Air Cooling Method

An air cooled shaker features a centrifugal blower for forced air cooling. A hose pipe connects the bottom of the shaker to the blower which sucks air from a perforated sheet at the top of the shaker. It is very important to ensure that the blower is not located in close vicinity of the shaker because this might cause the exhaust air from the blower to be sucked back by the shaker. In this scenario, the shaker’s temperature will keep increasing as it is being cooled by the same air in a loop, causing thermal runaway and even burning of the armature coil. To ensure safety and proper operation of the cooling system, various sensors are installed in the shaker that are mentioned below:

Due to suction, audible noise is always present near the shaker and the blower. It is suggested to take measures during installation to prevent this audible noise from creating an un-conducive working environment for the test/ lab personnel.

Water Cooling Method

A water cooled shaker features a dedicated cooling system for storing, circulating, and cooling distilled water that is used for cooling. The system is assembled in two 19-inch racks of 42 unit height. Pressure pump is installed in the cooling rack to circulate distilled water at high pressure through the shaker’s field and armature coils. Heat exchanger is installed in the cooling rack to cool this distilled water with another supply of water from a cooling tower or chiller at the customer’s site. To ensure safety and proper operation of the cooling system, various sensors are installed in the cooling racks that are mentioned below:

• Liquid Pressure Sensor – To measure the water pressure in the pipes in order to detect any obstruction in the pipeline
• Liquid Flow Sensor – To measure the water flow in the pipes in order to detect any leakages in the pipeline
• Liquid Temperature Sensor – To measure the temperature of the incoming and outgoing water in order to detect overheating
