What to pay attention to before buying a generator

1. First of all, we should pay attention to the selection of diesel generator set manufacturers, and pay attention to the first is the first of the manufacturers' units, whether they are at the average level of the same industry, and you can shop around. The second is the scale of the company, which has a certain scale of factories and is relatively reliable in terms of quality. The third is after-sales service.

Fourth, accessories and consumables, if it is an imported unit, see whether the manufacturer has enough imported accessories and consumables.

2. Pay attention to the relationship between KVA and KW. The relationship between them is ikva=. Imported diesel generator sets generally use KVA to express the power unit, while domestic electrical equipment is generally expressed in KW, so KVA should be converted into KW by 2% when calculating power.

3. The relationship between the long line (rated) power and the backup power, only one "power", and the backup power is sold to customers as the long line power. Actually, backup power = long line power. Moreover, the backup power can only be used for 1 hour of 12 hours of continuous operation.

4. The purpose of the unit. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for diesel generator sets for different purposes are different.

5. Load capacity. The load capacity and the load change range should be selected according to different uses, and the single capacity of the diesel generator set and the standby diesel generator set capacity should be determined.

6. The use of environmental conditions of the unit (mainly referring to altitude and climatic conditions) The selection of diesel generators, the selection of generators and excitation methods, and the selection of automation functions of diesel generators.

When buying a generator set, there are the following points that need to be paid more attention to by owners and friends:

1. The owner should understand what the electrical equipment is, what is the power, whether the generator set is used as the main power supply or backup power supply, and then finalize the power of the required generator set.

2. The owner should confirm the use environment of the generator set, whether it is used outdoors or indoors, and whether it needs to be moved frequently. This is used to finalize the style of the generator set.

3. The owner's requirements for the degree of automation of the generator set and cloud services, etc.

4. Finalize the diesel engine and generator brand of the generator set according to the budget.

5. The owner looks for multiple generator set manufacturers on the Internet, and comprehensively compares the manufacturer's production capacity, research and development capabilities, pre-sale, in-sale and after-sales service capabilities to finalize the diesel generator manufacturer.

The general power of diesel generator sets is from 8 to 2000kw, and the brands of diesel generators include Cummins generators, Perkins generators, Volvo generators, Yanan generators, Yuchai generators, Weichai generators, Shangchai generators and other brands. Generally, diesel generators include stationary generators, mobile generators, silent generators, containerized generators and other styles.

Application fields of diesel generator sets.

1. Mines. The diesel generator set can be fixed on the foundation as a whole, positioned for use, or installed on a trailer for mobile use. Therefore, it is widely used in mines.

2. Marine and port.

Large ports have a large number of ships calling at each day, and the powerful diesel engines on board the ships must run continuously to keep the ship's equipment and support systems running.

3. Field construction sites.

Due to its small size, flexibility, lightness, complete facilities, easy operation and maintenance, it is widely used in field construction sites and other departments as a backup power supply or temporary power supply.

Fourth, municipal machinery.

Yanan Motor Tips: Diesel engines are widely used due to their high thermal efficiency. Off-highway diesel engines are the main body of the off-highway engine market, mainly used in agricultural machinery (such as tractors), construction machinery (such as excavators, loaders, bulldozers), material handling machinery (such as forklifts) and multi-purpose equipment (such as generator sets, pumps), etc.

5. Building construction.

The high-performance and stable generator set adopts a low-noise design to ensure that the replacement power system must be able to provide power immediately in the event of a mains power outage. Support the normal operation of all types of buildings and facilities around the world.

Sixth, special for breeding.

Farms are generally built in relatively remote places, and electricity is inconvenient, so generators are a must-have magic weapon for major farms. Aquaculture is an industry that uses more generator sets.

Precautions for buying a generator:

1.The first thing to determine how much power the generator set is selected, the diesel engine power should be more than 30% larger than the selected power, and the power of the electric distribution machine should be set aside for 10% reserve, if there is a high-power single motor (non-frequency conversion start), the diesel engine power needs to be 3 times the power of the motor to start the motor smoothly;

2.The diesel engine should be considered with mature technology with low fuel consumption, low maintenance cost and high reliability configuration.

3.The selection of the generator set control unit should consider the place used by the user, such as the rental industry or the operator is not accustomed to using the LCD screen of the unit can choose the manual screen, and the place with high automation requirements can choose the full LCD screen;

4.When purchasing, it is also necessary to prevent bad manufacturers from cheating on the power of generators and diesel engines, and whether the cooling water tank and generator are made of pure copper should also be asked in the configuration of generator sets.

There are several factors in the purchase of generator sets, mainly including:

1) If there is a gap between the environmental conditions of use and the calibrated environmental conditions of the diesel generator set, the temperature, humidity and altitude value should be stated when signing the contract to provide suitable models and supporting equipment;

2) Explain the cooling method adopted in use, especially for large-capacity units, which should be paid more attention to;

3) When ordering, in addition to the model of the unit, it is also necessary to indicate what kind of model to choose;

4) The voltage regulation rate of diesel unit is as follows5% of the rated voltage. The choice should also be specified;

5) When the normal supply, provide a certain amount of wearing parts, and if necessary, it should also be explained.

Answer hello, detail 1: When the newly bought generator arrives, the user will first compare the parameters, quantity, configuration, model, generator manufacturer, and additional product requirements with the generator according to the parameters ordered by the generator contract, and communicate with the generator manufacturer in time if it is found to be inconsistent.

Detail 2: Check whether the appearance of the generator is damaged or have traces of collision to prevent damage during transportation and handling, and open the packaged products on site to carefully inspect.

Detail 4: Check and keep the software information of the generator: certificate, manual, warranty content, spare parts list, etc.

Precautions for purchasing generator sets:

1. Purpose: whether the generator set is used as the main power supply or standby power supply, and then finalize the power of the required generator set. Understand what electrical equipment is and what the power is, 2. Use environment: confirm whether the generator set is used outdoors or indoors. Whether it needs to be moved frequently, determine whether the style of the generator set is a fixed generator set, a silent generator set, a mobile generator set, whether there are environmental protection requirements, and whether the machine room is equipped with noise reduction.

3. Degree of automation of the generator set: the instrument panel and the four protection generator sets are suitable for outdoor ordinary units; The standby power supply is suitable for automatic generator sets with self-start and self-stop; Applicable to leasing cloud services, generator sets, etc.

4. Determine the diesel engine and generator brand of the generator set according to the budget: high-end diesel engine brands include MTU (Mercedes-Benz), Perkins, Volvo, etc., mid-range diesel engine brands include Cummins, Deutz, Scania, Daewoo, etc., and domestic brands include Yuchai, Weichai, Hanma, Nantong and other domestic brands; Generator brands include brands such as Stanford, Marathon, Leroy Somer, Faraday, and so on.

5. Look for regular manufacturers of generator sets locally, and comprehensively compare professional service capabilities to determine the purchase of generator sets.

Everyone will encounter some unscrupulous merchants when buying generators or generator sets. However, due to their own limited understanding and familiarity with the generator, how can we reduce the loss and be deceived when buying a generator?

a.Attention should be paid to the relationship between KVA and KW. Some merchants will confuse KVA as KW to exaggerate power.

b.Ask whether the power is common or standby.

c.Whether the power configuration of the diesel engine is the same as that of the generator.

d.When inspecting the machine, pay attention to whether the refurbished unit is sold as a second-hand unit.

e.Only report the diesel engine brand, not the generator brand.

f.Pay attention to whether the generator brand uses the same phonetic word, or whether the same sound is from different origins, these should be noted.

g.Pay attention to whether it has a non-protection function.

h.There are no bearded pants, there is a provision of after-sales service and accessories, pants and simple supply.

i.Be sure to check what attachments you bring, preferably on the contract. Sign to confirm that this is guaranteed. Or go to a regular and trustworthy merchant to buy.

First, when purchasing power generation welding machine products, it is necessary to go to regular production enterprises or large shopping malls to buy, and to buy brand famous products with high market share. Don't go to a small store to buy it cheaply, where the quality of the welding machine cannot be guaranteed.

Second, when purchasing, check whether the nameplate on the product has the name of the manufacturer, production address, specification and model, welding current adjustment range, load duration rate and input voltage and current and other content, and then determine the power generation welding machine you want to buy according to the needs of the work.

Third, when purchasing, the dealer can be required to provide a product quality inspection report or certificate. Because the welding machine product is a national compulsory certification product, it is necessary to confirm whether the product has passed the "ISO9001" certification when purchasing. You can also check online.

Fourth, when purchasing, be sure to check whether the product has grounding screws, and the grounding screw connection should be paintless and well grounded. Whether the movement is clean and whether the insulation is damaged or not to ensure the safety of use, if necessary, can also be checked.

Fifth, before purchasing, you can power on to check the operation, conversion and installation of the switch on the panel, the power indicator light on and off, whether the fan is normal, whether the power supply part has abnormal vibration and buzzing sound, whether there is peculiar smell, whether there is discoloration and other heating phenomena in the appearance, so as to ensure the quality of the power generation welding machine and give full play to the performance of the power generation welding machine.

Sixth, if you want to buy a gas shielded welding machine, you should also check whether the accessories are complete, whether the wire feeder has oil stains, whether the rotation is stable, whether the connecting cable matches the surface insulation and whether there is damage, so as to ensure the stability of the arc.

When buying a generator set, you should pay attention to the following:

1. First of all, you must figure out the type and power of the equipment you buy with the generator, communicate with the dealer, and confirm how much power the generator to buy. In this way, we can avoid the waste of buying a large amount of equipment and the situation that you can't bring the equipment if you buy a small one.

2. Check that the generator set certificate includes the production license, product qualification certificate, trademark registration certificate, and other 'three certificates'. Unlicensed products are prone to problems such as quality and counterfeiting, causing hidden dangers to consumers' property and even personal safety.

3. Check whether the information provided is consistent with the actual information. There is a nameplate on the generator, the internal combustion engine, and the whole machine. If the information displayed on the certificate does not match the nameplate number, there is a high probability that there will be a problem.

4, the choice of after-sales service: buy generators when it is recommended that well-known brands and regular manufacturers of products, some small brands and small dealers of the products although cheaper, but once the generator fails, it is difficult to get after-sales service guarantee, 5, choose quality: now is the Internet era, information is more transparent, buy to shop around, choose excellent quality products, to believe in the truth of a penny, not only cheap, ignore the quality, take advantage of the small advantage and suffer a big loss.

6. To certify the qualifications of manufacturers and distributors, in 2014, the State Administration for Industry and Commerce has opened the "National Enterprise Credit Information Publicity System", you can easily check the most authoritative credit information of the enterprise, and identify those false propaganda enterprises. So as not to be deceived.

7. It is necessary to sign a good sales contract, and clarify the rights and obligations of both parties, the brand, model, specification, and after-sales service of the product through the sales contract. In order to get full pre-sale, in-sale and after-sales service.

First of all, you must determine the power you want to use, and then determine what brand of generator you want to choose. Find some big generator manufacturers. That's it. Details can be found here. Fuheng generator.

I'm a generator manufacturer.

Diesel generator** misunderstanding:

1. Blindly compare which diesel generator is how much it is, ** lower, confused by low prices, and do not judge whether the quality and product output power can be achieved;

2. Ignoring the after-sales service ability of a professional manufacturer is of great help to reduce product maintenance costs;

3. Insufficient attention is paid to product quality, ignoring the importance of vibration resistance, power performance and long-term output stability of diesel generators for applications;

4. I only care about the first business and say that I am a manufacturer, and I have never seriously reviewed whether the first business really has the production qualifications, and whether the scale of the manufacturer and the service staffing can really meet the customer service requirements.
