How to Correctly Select 400kw Yuchai Diesel Generating Set

The 400kw Yuchai diesel generator set, as a well-known brand among domestic generator sets, is deeply loved by customers. The 400kw Yuchai diesel generator set is a small power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. There are now many types of generators, gas engines, and diesel engines on the market. Compared to diesel generators, although the fuel cost is relatively expensive, diesel generators are favored by many consumers among many different types of fuel generators due to their convenient purchase, wide applicability, high horsepower, high efficiency, and easy maintenance. Whether as a common power supply or a standby power supply, the 400kw Yuchai diesel generator set has the advantages of good fuel economy and simplicity. Many enterprises do not know the advantages and disadvantages. After purchasing fake and inferior diesel generator sets, they can not generate electricity, but also bring hidden dangers. After investigation, it is found that almost all the well-known 400 kw Yuchai diesel generator sets in the domestic market are counterfeit. So how can we distinguish authenticity?

The 400kw Yuchai diesel generator set is mainly divided into four parts: diesel engine, generator, control system and accessories.

1.Diesel engine

The diesel engine is the power output part of the whole genset, accounting for 70% of the cost of the 400kw Yuchai diesel generator set. It is a link that some poor manufacturers like to fake.

(1) Counterfeiting machine

At present, almost all well-known diesel engines in the market have imitation manufacturers. Some manufacturers use these identical imitation machines to impersonate them, using methods such as making fake nameplates, printing genuine numbers, and printing fake factory documents to fake them and achieve the goal of significantly reducing costs. It is not difficult for professionals to distinguish between deck machines.

(2) Refurbishing old machines

Each brand has refurbished old machines, which may be difficult to distinguish if not a professional.

But there are still some flaws in the refurbishment machine, such as paint, especially dead corner paint, which is difficult to achieve consistency with the original factory.

(3) Confusing the public with similar factory names

These manufacturers are opportunistic and dare not engage in fake licensing or refurbishment. Instead, they use similar factory names to confuse diesel engine names.

For example, some manufacturers use pinyin or homophonic characters or even the same characters to register their own brands, such as certain Cummins generator set companies, KMS generator sets, etc., which are not actually related to Cummins engines, but only registered the name of certain generator limited companies, and have no connection with the Cummins trademark, The generator sets of various miscellaneous diesel engine configurations purchased by these manufacturers are all referred to as Cummins generator sets to the public.

2.Alternator part

The function of a alternator is to convert the power of a diesel engine into electrical energy, which directly affects the quality and stability of the output power.

(1) Stator coil

The stator coils were originally made of all copper wires, but with the improvement of wire manufacturing technology, copper clad aluminum core wires emerged. Unlike copper plated aluminum wire, copper clad aluminum core wire is formed by using a special mold with copper clad aluminum, and the copper layer is much thicker than copper plated. The use of copper clad aluminum core wire for the stator coil of the generator has no significant difference in performance, but its service life is much shorter than that of all copper wire stator coils.

(2) Excitation method

The excitation methods of alternators are divided into phase compound excitation and brushless self excitation. Brushless self-excited alternators have become mainstream due to their advantages of stable excitation and simple maintenance, but some manufacturers still configure phase compound excitation alternators in generator sets below 300KW due to cost considerations.

3.Control system

Ordinary standard units need manual switching. It usually takes 10 to 30 minutes from power failure to the start of 400kw Yuchai diesel generator set for power transmission.

The automatic control of 400kw Yuchai diesel generator set is divided into semi-automatic and full-automatic unattended type. The semi-automatic system automatically starts the generator set when there is a power outage and stops it when there is an incoming call, saving the time for starting and stopping, but it still requires manual switching.
