FAQ

First, product selection

  1. How to determine the power size of the oil-fired generator set according to the electricity demand?
    A: First of all, it is necessary to calculate the total power of all electrical equipment that may run at the same time, and then take into account the starting current of some equipment (usually the starting current is several times the rated current), it is generally recommended to choose the power of the generator set is about 20%-30% larger than the total calculated power to ensure stable power supply under various working conditions. For example, if the total calculated power is 100kW, then it is more appropriate to choose a generator set of 120-130kW.
  2. What types of fuel are available for fuel generating sets, and what are the characteristics of each?
    A: There are two common diesel and gasoline. Diesel generator set has high fuel efficiency, wide power range, suitable for long-term continuous operation, often used in industrial, commercial and other places with large and continuous demand for power; Gasoline generator set is relatively small, light weight, more convenient to start, often used for family emergency backup power supply or some small equipment power supply, but the operating cost is relatively high, and the continuous running time is generally short.
  3. The price difference of different brands of fuel generator sets is large, mainly reflected in what aspects?
    A: The brand difference is mainly reflected in the quality of the generator, performance stability, technical advancement, parts durability and after-sales service. Well-known brands usually invest more in research and development, products have higher power generation efficiency, can better adapt to different environments and load changes, and have more advantages in after-sales network coverage and response speed, so the price is relatively high. Some small brands or unknown brands may be more strict in cost control and lower prices, but there may be risks in terms of quality and after-sales protection.

Ii. Export logistics

  1. What special procedures and documents do you need to handle for the export of fuel generator sets?
    Answer: Generally need to go through the export declaration procedures, provide commercial invoices, packing lists, contracts and other conventional customs declaration documents. In addition, because the fuel generator unit involves the fuel system and belongs to the category of dangerous goods, it is also necessary to handle the identification report of dangerous goods transportation, dangerous package certificate and other related dangerous goods export documents to ensure that it meets the requirements of international sea transportation and air transportation for dangerous goods.
  2. What are the special requirements on the packaging of the export fuel generator set?
    A: The packaging should ensure the safety of the generator set during transportation to prevent collision, vibration and moisture. For dangerous goods (such as fuel tanks), special protective packaging materials should be used, and they should be marked in accordance with the packaging specifications of dangerous goods, indicating the category of dangerous goods, United Nations number and other information. At the same time, the packaging should meet the relevant standards and regulatory requirements of the destination country, for example, some countries may have fumigation requirements for wood packaging.
  3. How to choose the right international logistics transportation mode to transport fuel generator sets?
    A: If the transportation time requirements are not particularly urgent, and the volume of goods is large, sea transport is a more economical choice, can be transported by container transport or bulk carrier, but the transportation cycle is longer, generally takes several weeks or even months. If the goods are urgent and relatively small, air freight can be delivered quickly, but at a higher cost. In addition, for countries or regions bordering on land transport, road transport or rail transport can also be considered, which is between sea and air transport in terms of transport time and cost. In the selection also need to consider the volume of the goods, weight, destination, transportation cost budget and other factors.

Third, product installation

  1. What are the requirements for the installation site of the oil-fired generator set?
    A: The site should be kept dry, well ventilated, to avoid wet and water environment, to prevent the generator set and electrical parts from being damaged by moisture. To have enough space for easy operation, maintenance and heat dissipation, generally reserve at least 1-2 meters of space around. The ground should be smooth and solid, able to withstand the weight of the generator set, if installed indoors, it is also necessary to consider the installation of smoke exhaust pipes and ventilation facilities to ensure indoor air circulation and avoid exhaust gas accumulation.
  2. How to make the installation base of oil-fired generator set?
    A: For small generator sets, if the ground conditions are good, the concrete foundation or steel base can be placed directly on the flat ground and fixed with bolts. The large generator set needs to design a special concrete foundation according to the weight, size and vibration of the unit, the depth of the foundation is generally about 1-2 meters, to ensure that the foundation has enough strength and stability to withstand the dynamic load and static load of the unit during operation, when pouring the concrete foundation, it is necessary to reserve the anchor bolt hole for the installation of the unit fixed.
  3. What should we pay attention to in the electrical connection of the oil-fired generator set?
    A: First of all, ensure that the output voltage and frequency of the generator set match the electrical equipment. The cross-sectional area of the connecting cable should be selected according to the rated current of the generator to ensure that the cable is not loaded with heat. The cable connection should be firm, and the joint should be insulated to prevent leakage. When connecting a power distribution box or a load, follow the electrical installation specifications and correctly connect the neutral, live, and ground wires to avoid device damage or accidents caused by incorrect connections. At the same time, appropriate circuit breakers, leakage protectors and other protective devices should be installed in order to cut off the circuit in time when overload, short circuit or leakage occurs.

Four, the use of precautions

  1. What preparations do you need to make before the first start of the oil-fired generator set?
    A: Check whether the fuel in the fuel tank is sufficient, whether the fuel pipeline is tightly connected, no leakage; Check whether the oil level is within the normal range and whether the oil quality is good; Check whether the water level of the cooling water tank is normal and whether the coolant meets the requirements; Check whether the battery power is sufficient and whether the electrode connection is firm; Check whether the air filter is clean, if there is a blockage to clean or replace; Check whether the electrical connection parts are firm, no loosening phenomenon; Check whether the smoke exhaust pipe is unobstructed and not blocked or damaged.
  2. How should the oil-fired generator set be monitored during operation?
    A: Observe the parameters on the instrument panel at any time, such as voltage, current, frequency, water temperature, oil temperature, oil pressure, etc., to ensure that these parameters are within the normal range. Pay attention to the generator running sound is normal, there is no abnormal vibration or noise, if found abnormal should immediately stop the check. At the same time, pay attention to the smoke color, the normal should be light gray, if the smoke color turns black, blue or white and accompanied by a strong smell, it may indicate insufficient combustion or other faults, need to be dealt with in time.
  3. What are the safety precautions of the oil-fired generator set during use?
    A: It is strictly prohibited to use in a closed or poorly ventilated environment to prevent the accumulation of exhaust gas leading to poisoning. When the generator set is running, inflammable and explosive materials should not be placed around it to avoid fire or explosion accidents. Wear protective equipment, such as gloves and goggles, to avoid touching hot parts or being damaged by rotating parts. When adding fuel, it must be stopped first and wait for the unit to cool down, and refueling is strictly prohibited during operation to prevent fuel spatter from causing fire.

Five, after-sales problems

  1. How long is the warranty period of the fuel generator set, and what is the warranty coverage?
    A: The warranty period of different brands and models of generator sets is different, generally about 1-2 years. The warranty scope usually includes the quality problems of the main components such as the generator host and the engine, but does not include the faults caused by improper human operation, poor use of the environment, failure to maintain or use non-original parts according to regulations. For example, in the normal use of the engine internal parts damage, generator winding short circuit and other problems within the scope of the warranty, and poor fuel quality caused by fuel injection nozzle blockage, due to long-term oil change caused by engine wear is not within the scope of the warranty.
  2. How to carry out the daily maintenance of the oil generator set?
    A: Replace the oil and oil filter regularly, generally every 200-500 hours of operation, depending on the use; Clean the air filter regularly, check it every 100-200 hours of operation, and clean or replace it if necessary; Check the fuel filter and replace it in time if there is blockage; Check the cooling system to ensure sufficient coolant and normal circulation, and clean the water tank and radiator regularly; Check battery power and electrolyte level, charge or add distilled water in time; Check electrical connection parts regularly and tighten loose bolts; After running for a certain time, check and maintain the brush, slip ring and other parts of the generator to ensure that they are in good contact.
  3. How do I get after-sales service support if a fuel generator fails?
    A: During the warranty period, you can call the manufacturer or dealer after-sales service phone, describe the fault phenomenon in detail, they will arrange professional and technical personnel for fault diagnosis and maintenance. Some large brands have after-sales service outlets around the country, and technicians can provide on-site service in time. For failures beyond the warranty period, you can also contact after-sales service personnel, they will provide paid maintenance services, including troubleshooting, parts replacement, etc. At the same time, many manufacturers now also provide online technical support, through the official website or customer service platform to consult troubleshooting methods.
