When the battery of the diesel generator set has not been used for a long time, it must be properly charged before use to ensure the normal capacity of the battery. (The actual capacity of the battery can be detected through a hydrometer) Normal operation and charging will cause some water in the battery to evaporate, which requires frequent rehydration of the battery. Before rehydration, first clean the dirt around the filling port to prevent it from falling into the battery compartment, and then remove the filling port. Open and add appropriate amount Do not overfill the distilled or purified water (based on the scale on the battery plate). Otherwise, when the battery is discharging/charging, the electrolyte inside the diesel engine will gush out from the overflow hole of the filling port, causing damage to the surroundings. Corrosion damage to objects and environment. Avoid using the battery to start the unit at low temperatures. The battery capacity will not be output normally in low temperature environments, and long-term discharge may cause battery failure (cracking or explosion). The batteries of the standby generator set should be maintained and charged regularly and can be equipped with a float charger. diesel fuel

The editor reminds customers to be careful of the eight major traps that should be paid attention to when purchasing diesel generator sets. 1. Confusing the relationship between KVA and KW. Treat KVA as KW to exaggerate the power and sell it to customers. In fact, KVA is the apparent power and KW is the effective power. The relationship between them is IKVA=0.8KW. Imported units generally use KVA to express the power unit, while domestic electrical equipment is generally expressed in KW, so when calculating power, KVA should be converted into KW at a 20% discount. 2. We do not talk about the relationship between long-line (rated) power and backup power. We only talk about 'power' and sell the backup power to customers as long-line power. In fact, reserve power = 1.1x long line power. Moreover, the backup power can only be used for 1 hour out of 12 hours of continuous operation. 3. The power of the diesel engine is configured to be the same as that of the generator in order to reduce costs. In fact, the industry generally stipulates that diesel engine power ≥ generator power 10%, because

The manufacturer believes that this problem may be caused by damage to the fuse or rectifier diode. When the fuse is blown, the charger's power indicator light does not light up; after the rectifier diode is damaged, the charger's power indicator light turns on, but there is no DC output. 1. The charger transformer is burned out. 2. The diode on the charger is burned out. 3. The charging ammeter of the charger is damaged. 4. The fuse of the charger is burned out. The troubleshooting method is: disconnect the connection line between the charger and the battery, use a multimeter with a DC voltage range (50V) to test the voltage between the two output terminals of the charger. Note that the red test lead is connected to the positive pole of the charger, and the black test lead is connected to the negative pole. No voltage output was found. Remove the charger casing and check the charging fuse. It is found that the 60A fuse is burned out. After replacement, the charger resumes normal charging and the fault is eliminated.

When a diesel generator set is shut down, it is mostly because the unit has been in a static state for a long time. The various materials of the unit itself will undergo complex chemical and physical changes with the oil, cooling water, diesel, air, etc. This is mainly manifested in two aspects, which are summarized as follows: : The filtration capacity of the filter decreases. The filter plays a role in filtering diesel, engine oil or water to prevent impurities from entering the body. Oil dirt and impurities are also inevitable in diesel, so during the operation of the unit, the filter plays a role. important role, but at the same time these oils or impurities are also deposited in On the filter wall, the filtration capacity of the filter will be reduced, and there will be too much sedimentation, and the oil circuit will not be smooth. In this way, when the oil machine is running under load, it will go into shock due to the inability to supply oil (like a person lacking oxygen). Therefore, during normal use of the generator set Among them, the editor of the diesel generator public platform recommends: 1. Every 500 for commonly used units Replace the third filter every hour; 2. Replace the third filter of the backup unit every two years. Cooling system
