FTG Technical Tuesday – Load Bank Testing

FTG Technical Tuesday – Load Bank Testing

Load testing your generator system should be part of a standard planned maintenance program for all systems. The main reason to test your system under load is to make sure the generator will perform as designed, when it is needed most. This is the only true way to check the performance of the generator. A load test will allow verification that the generator system will produce and maintain full load without overheating and shutting down. It also allows testing of all components of the system, to ensure all work together as designed and intended and can help identify any potential weaknesses in controlled conditions. This allows proactive maintenance, as weaknesses are identified during controlled conditions.

Benefits of Load bank Testing

  • Verifies, the generators capabilities as opposed to just starting it up.
  • Helps to avoid “wet stacking” and cleans out carbon deposits.
  • Verifies the engine cooling system will perform properly under load

FTG Technical Tuesday – What is Wet Stacking?

With the new Tier 4 emissions requirements, especially in a rental application, it is very important to properly load bank a generator when it is returned. Customer’s requirements sometimes fall short of proper use of a generator. Sizing a generator too large for the job at hand, sizing a generator by fuel tank size instead of load, etc. All these issues can and will contribute to poor performance of the generator overtime. The most common issue is wet stacking. Wet stacking is when a diesel engine operates without sufficient load, it will operate at below its optimum temperature. This will allow unburned fuel to accumulate, foul the fuel injectors, engine valves and exhaust system, including turbochargers, and reduce the operating performance. Symptoms of wet stacking are oily residue found around the turbo charger, leaking from the exhaust manifold gaskets and in and around the exhaust stack. Next week we will discuss Load Banking procedures. Have a technical question? (855) 303-7900 or nick@ftgequipment.com

FTG Technical Tuesday – What is the purpose of a check valve on an air compressor? An air compressor check valve has only one function: to let air flow from one side to the other, while blocking air flow in the opposite direction. Once the compressed air passes the check valve, there is no way it can go back again. With the help of a check valve, a compressor can keep certain parts pressurized and other parts de-pressurized. Check valves also prevent that compressed air that has left the compressor (to the piping / air tank) back into the compressor. Have a technical question?
