Knowledge of Electronic Actuators in Cummins Diesel Generators

In the process of using diesel generator sets, due to daily maintenance and operation, users may have a certain understanding of the relevant technical knowledge of the units. However, when it comes to the detailed components of the units, many users may find it challenging. For mechanical equipment, even a small accessory failure can potentially cause the unit to break down and stop running. Therefore, when using these large and complex mechanical devices, it is necessary to master more professional knowledge to help extend the service life of the unit and avoid the occurrence of faults. Today, the editor from Dingbo Power in the generator knowledge class will share relevant knowledge points about electronic actuators in the fuel system of Cummins diesel generator sets.

Electronic actuators are stable and reliable in operation, have strong load-bearing capacity, long service life, and can be used with various corresponding control boards, thus being widely welcomed by diesel generator sets. In addition, in the fuel system of diesel generator sets, the electronic actuator is an indispensable part and exists as an important component of the fuel system.

The coil of the electronic actuator of the diesel generator set can be tested using the ohm档 of a multimeter on the two terminals of the coil, and the resistance value is usually set between 7-8 ohms. When the generator is running at no load, the voltage value transmitted by the electronic speed control board to the electronic actuator is generally between 6-8vdc. This voltage value will increase with the increase of the load, and when the generator is at full load, it is usually between 12-13vdc.

If the voltage value of the diesel generator is lower than 5VDC when the unit is at no load, it indicates that the electronic actuator is excessively worn, and at this time, the electronic actuator needs to be replaced; when the diesel generator set is under load, if the voltage value is higher than 15VDC, it indicates insufficient fuel supply from the PT fuel pump.

1.Electronic actuators have two working modes: normally closed and normally open. The more commonly used one is the normally closed actuator, which is used together with a normally closed electronic speed control board.

2.Electronic actuators are divided into low-flow and high-flow actuators. High-flow actuators can be used in VTA28, KKTA50, and KTA38 series, while low-flow actuators can be used in LTA10, K19 series, and N series.

According to the chronological order, the part numbers of high-flow actuators are 3063505, 3085220, and 3408326 respectively.

According to the chronological order, the part numbers of low-flow actuators are 3063504, 3085219, and 3408324 respectively.

The above is the professional sharing about the electronic actuators of diesel generator sets by Dingbo Power, a Cummins generator manufacturer. We hope it can be helpful to everyone. Guangxi Dingbo Generator Set Manufacturing Co.,Ltd. was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China.
