Is there any way to cool the diesel generator set in high temperature weather?
When the static diesel generator set reaches a high temperature rise, the power of the silent diesel generator will be affected. So what should our users do? In order to adapt to the special environment, the silent diesel generator set can reduce the noise of the diesel generator set to a certain decibel, so that no noise will pollute our environment.
Generally, the mute diesel generator sets are designed by the generator manufacturers as electrostatic speakers to reduce noise. The static speakers are at the bottom of the fuel tank, and are all around the box. In summer, the ambient temperature of the silent diesel generator set can be as high as 40 ° or more, and the static speaker temperature is high. When the unit temperature is too high, the performance must be set, and the power is also reduced.
Silent diesel generator sets are generally placed outdoors. The sun exposure in summer is the root cause of temperature rise. Therefore, it is very necessary to use diesel generator sets to select the appropriate environment in summer. The universal use of geographical environment does not allow the unit to be completely exposed to the hot sun and areas with strong air mobility, which can increase the heat dissipation advantage.
By reducing the load of the unit, the progress of the temperature rise of the brushless diesel generator set is controlled, because the temperature of the unit under high load will rise rapidly, affecting the power distribution of the unit.
In addition, based on many years of practical experience, generator manufacturers have developed a fan cooling method that can effectively solve the problem of temperature rise of silent diesel generator sets. That is, the fan is installed on the mute box, and the air flow in the box is increased by the exhaust fan, and the air convection in the box is increased to better heat the unit.
By calculating the amount, the housing needs more powerful fans, more fans are added to high-power diesel generator sets, and where are they installed. Combining with the scientific and effective practical experience of installing exhaust fans to ensure that silent diesel generator sets are used in high temperature Normal use and effective power.
- Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.
- Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0
- In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
- The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
