The heat dissipation of biogas generator set is very important. However, with the increase of operation time and improper operation, the radiator failure of biogas generator set will be caused. The main reason is that the water in the air corrodes the radiator, accelerates the aging of the radiator and causes the failure of the unit radiator. What shall I do?
The pipe joint of biogas generator set shall be checked frequently to prevent water leakage, and water shall be added regularly from the top of radiator to discharge air, so as to maintain “no air” in the system.
1. The radiator of biogas generator set should not be in the condition of partial water injection and discharge, because this will accelerate corrosion.
For the non working biogas generator set, all water shall be pumped out or filled. If possible, use distilled water or natural soft water, and add an appropriate amount of antirust agent.
2. The coolant of the radiator is usually very hot and under pressure.
Do not tidy the radiator or remove the pipes when it is not cooled. Do not work on the radiator or open the fan protection cover when the fan is running.
3. External cleaning:
In a dusty or dirty environment, the joint of the radiator may be blocked by debris, insects and other things, which will affect the efficiency of the radiator. The regular cleaning of these light sediments can be sprayed with low-pressure hot water and detergent to spray steam or water from the front of the radiator to the fan. Spraying in the opposite direction will only bring the dirt close to the center. When using this method, cover the biogas generator set with cloth.
4. What if stubborn sediments cannot be cleaned up in the above way?
The radiator of biogas generator set can be removed, soaked in hot alkaline water for about 20 minutes, and then washed with hot water. If the hard water filling method is selected for a period of time because of the leakage of the joint, or because the generator has been running for a period of time and there is no rust remover, the system may be blocked by scale.
As the weather and temperature rise, attention shall be paid to the maintenance of the unit:
1. Pay attention not to affect the normal ventilation and cooling of the generator set. The dust and dirt in the ventilation duct shall be cleaned frequently and extended in all directions.
2. Summer is a season with frequent thunderstorms. It is necessary to do a good job in the local lightning protection operation of the generator set. All kinds of mechanical equipment and projects under construction must be well grounded according to the rules, and the generator set equipment must be well maintained and connected to zero.
3. If the generator set is installed, it shall be interlocked with the power supply of external power lines. Switching equipment or dual power general distribution box can be set to prohibit parallel operation. Cut off the power supply of all kinds of mechanical equipment after work to avoid all kinds of electric shock.
4. The disassembly and assembly method of the generator is roughly the same as that of the asynchronous motor, but due to the large weight of the generator, pay attention not to be bruised during disassembly and assembly. When removing the end cover, be careful not to damage the stator coil protruding from the base; When taking out the rotor, cardboard shall be padded between the stator and rotor of the motor to prevent damage to the iron core and winding. When binding the rotor with steel cable, the steel cable shall not touch the rotor journal, Phoenix fan, collector slide and easy-to-hand lead.
