Kind reminder:
In the face of the uneven quality of small generators in the market, consumers are reminded to pay attention to the following issues when purchasing small generators:
1. The "three certificates" including production license, product qualification certificate, and trademark registration certificate should be complete. Products without certificates are prone to quality and counterfeiting issues, posing hidden dangers to consumers' property and even personal safety.
2、 Verify whether the provided information matches the actual materials. There is a nameplate on each of the small generator, internal combustion engine, and complete machine. If the information displayed on the certificate of conformity does not match the nameplate number, there may be a problem.
3、 Sign a contract to clarify responsibilities. After purchasing a small generator, consumers should not forget to sign a contract with the merchant to clarify maintenance methods, responsibility allocation, and other issues.
4、 Choose a legitimate and reliable sales unit. Consumers' purchasing channels are not regular, they buy wherever it is cheap, or they resort to "emergency medical treatment" by paying for goods as soon as they are available, without even needing an invoice. This is also one of the reasons for the increase in complaints about small generators. The existence of this situation also brings unfavorable factors to consumers' protection of their own rights and interests.
5、 Improper user operation can also cause security risks.
For the safety of themselves and others, consumers are advised to voluntarily apply for a small generator at the power supply station or electrical management station, collect the form, register for installation, and take self-protection measures after purchasing it. When applying, it is necessary to bring the original electricity invoice, generator manual, and company seal, fill out one application form, and have the electricity supervision personnel conduct on-site inspection after installation. Those who pass the inspection will sign the "Non grid Self provided Power Supply Agreement".
Whether it is a diesel generator or a diesel generator installed, they are basically water-cooled generators equipped with water tanks. The water in the tank is used for cooling, not for burning.Generators are divided into 10 kW, 15-20 kW, and above 20 kW, etc;
1. If calculated based on each 10 kW electric motor, 10 10 kW engines can drive over 90 kW of machinery.
2. It would be more suitable for 10 generators of 10 kilowatts to drive machinery below 100 kilowatts. If it drives machinery above 100 kilowatts, the generator will be loaded, which will make it difficult for the generator to drive and the load can easily burn the motor.
Correction of automatic shaft and liner wear of diesel engine gear type oil pump:
·Due to the inherent component of the automatic gear in the oil pump and the radial thrust generated when the gear is forced to mesh, the shaft and bushing holes are prone to eccentric wear, resulting in an increase in clearance. Therefore, during the operation, oil leakage may occur due to the increase in clearance, resulting in a reduction in fuel supply;
·After the wear of the automatic shaft and bushing, the joint clearance can be restored by repairing the shaft neck or bushing. When there is slight wear on the shaft neck, simply press out the old bushing and replace it with a new bushing, while the shaft usually does not need to be repaired, so that the cooperation gap can be restored to the agreed range;
·When the wear of the shaft and bushing is severe and the cooperation gap is greatly increased, it is not only necessary to replace the bushing, but also to use chrome plating or oscillation welding to increase the diameter of the shaft, and then grind it to the standard scale to restore the cooperation requirements between the journal and bushing
