China Guangzhou generator rental diesel generator frequency and speed what is the relationship between the two? Guangzhou generator rental as a power generation equipment, widely used in daily life in daily life, with the popularization of electricity, rental generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. Although there are various forms, its working principle is based on the law of electromagnetic induction and the law of electromagnetic force.

So the general principle of its construction is: with the appropriate magnetic and conductive materials to form a magnetic circuit and circuit, electromagnetic induction with each other to produce electromagnetic power to achieve energy conversion. But in the use of diesel generators, often encountered like diesel generator frequency is too low such generator failure. How should it be solved? These require us to have a deeper understanding of the frequency and speed of the generator. In order to make you understand more about the frequency and speed of the diesel generator, the following is our introduction.

The frequency and speed of diesel generators are closely related. The relationship between the two is explained in detail below:.

At present, there are two normative definitions of frequency in the world: 50HZ and 60HZ. indicates that the alternating current + per second, - polarity change, we all know that the frequency is related to the rotational speed, so is it only the rotational speed will affect the frequency?

2. Let's take a look at the formula for calculating the frequency: F = number of magnetic pole pairs * speed / 60, such as diesel generators, the number of magnetic pole pairs is 2 pairs, the engine speed is 1500rpm, then the frequency F = 2 * 1500 / 60 = 50hz; to our domestic turbine generator, for example, the number of magnetic poles for a pair of generator speed of 3,000 rpm, so the frequency is F = 1 * 3000 / 60 = 50HZ.

Genset is a mechanical device that converts other forms of energy into electrical energy, driven by a hydraulic turbine, steam turbine, diesel engine or other power machinery to convert the energy generated by water currents, air currents, fuel combustion or atomic nuclear fission into mechanical energy, which is then converted into electrical energy by the genset.

Having said that, we might as well expand on this, if a customer needs a 60HZ diesel generator, what should we do? Diesel engine magnetic pole pairs are the same, to achieve 60HZ, can only change the speed, N = F * 60/2 = 60 * 60/2 = 1800 rpm. That is to say, if the customer needs a customized 60HZ diesel generator, we must make the generator set rotate at 1800 rpm.

After determining the number of magnetic pole pairs of a diesel generator, to ensure the stability of the frequency, it is necessary to ensure that the generator's operating speed is unchanged. In order to prevent the diesel generator from rotating unevenly due to torque pulsations, resulting in voltage fluctuations and flashing lights, the rotor of the diesel generator rental is also required to have a large rotational inertia, and the frequency of the inherent torsional vibration of the shaft system should be more than 20% different from the frequency of any alternating component in the torque pulsations of the diesel engine in order to avoid resonance and shaft breakage accidents.
