How To Check And Repair The Radiator Of Cummins Diesel Generator Set

Nov. 16, 2021

In the whole body of the Cummins diesel generator set, the heat dissipation water tank plays a very important role in ensuring the normal operation of the unit. If it is used improperly, the diesel engine and the generator set will be damaged in the lighter ones, and the diesel engine may be scrapped when it is more serious. The most common fault of the radiator is water leakage. After the radiator is found to be leaking, the radiator must be cleaned before the water leakage check. When checking, the following two methods can be used:

 

1. Block the water inlet and outlet of the radiator, install a joint from the overflow pipe or the drain plug, and inject compressed air of 0.15-0.3kgf/cm². Put the radiator in the sink. If there is a bubble, it is a leak.

 

2. Use watering method to check. During the inspection, block the water inlet and outlet of the radiator, and after filling the water inlet with water, observe whether there is water leakage. In order to find small cracks, you can apply a certain pressure to the radiator or make the radiator slightly vibrate, and then observe carefully , There will be water seeping out of the leak.

 

If the leak of the radiator is found, it must be repaired in time. Here are two repair methods:

(1) Welding repair of upper and lower water chambers.

When the upper and lower water chambers are not leaking, they can be repaired directly with solder. If the leaks are large, they can be repaired by welding with purple steel skin. When repairing by welding, apply a layer of solder on one side of the steel skin and the leaking part, place the steel skin on the leaking area, and then heat it with a soldering iron to melt the solder and weld the surrounding area firmly.

 

(2) Welding repair of radiator water pipe.

If there is a break in the outer water pipe of the radiator and the break is not large, use needle-nose pliers to remove a little of the heat sink near the water pipe and directly use solder to repair it. If the breach is large or the middle-level water pipe leaks, it should be handled flexibly according to the specific conditions, such as pipe jamming, pipe blockage, pipe connection and pipe replacement. However, the number of stuck tubes and blocked tubes should not exceed 10% of the total number of tubes, so as not to affect the heat dissipation effect of the radiator.
