For generator sets, different stages of use require different degrees of maintenance and repair work. Generally speaking, 3000-4000 hours require minor repairs; 6000-8000 hours require moderate repairs; 9000-15000 hours require major repairs. Let’s follow Haixing Power to see the specific content and requirements of different repairs. Large, medium and minor repairs of diesel generator sets require minor repairs: (Time: 3000 - 4000 hours) Check valve diesel generators, diesel generator sets,

When the diesel generator set overheated, the oil temperature will rise, destroy the normal lubrication effect, pose a threat to the normal operation of the diesel generator set, and in serious cases, it will cause accidents. Below we analyze the main reasons for overheating of diesel engines are: 1. Cooling system failure: lack of water in the radiator; damage to the water pump impeller, or blocked by sludge and debris; bubbles in the water pipe form air plugs; serious scale in the cooling system, or water passages are blocked; the fan belt is loose, and the fan working efficiency is reduced; the scale in the radiator is severe, and the external surface area is more polluted, which greatly reduces its heat dissipation efficiency. 2. The combustion process fails inlet, the exhaust valve is not closed tightly, and the valve clearance is too small; too much carbon deposit in the combustion chamber, which is poor in heat conduction, so that the heat in the cylinder cannot be transferred to the cooling water, causing the cylinder to be in

As we all know, generator set cylinders are one of the vulnerable components, and common damage is corrosion and wear. When the cylinder block is directly in contact with high-temperature and high-pressure gas, and when the piston reciprocates at high speed, the cylinder wall working surface bears a large lateral pressure and the resulting periodic force. If used and maintained improperly, it is easy to cause premature wear of the engine cylinder wall. Why are cylinders prone to corrosion and wear? How to effectively avoid such corrosion? The corrosion of the cylinder liner of the diesel generator set is the damage caused by the electrochemical action of acid substances. When the wall temperature of the cylinder liner is low, the water vapor entering the cylinder will condense into water droplets. These water droplets interact with combustion gases to form acids, such as organic acids, sulfuric acid, carbonic acid, etc., which condense on the cylinder wall to corrode the cylinder. Practice has proved that when the cooling water temperature is lower than 65-70℃, or when the diesel engine starts frequently at low temperatures, corrosion and wear will increase significantly. So,

When the diesel generator set arrives, where to install it is a question that many customers need to consider first. Haixing Power believes that everyone should think about two core issues: generator set installation site selection and exhaust design. One of the initial design decisions is to determine whether the generator set is indoors or outdoors. The overall cost and installation convenience of the power system depend on the layout and physical location of the equipment - generator sets, fuel tanks, ventilation ducts and blinds, etc. Special attention should be paid to the ventilation of the generator set. Since the generator set consists of several parts: diesel engine, generator, and control system, sufficient oxygen is required to burn and do work during the engine operation, and the cooling system of the generator and engine also requires fan exhaust and cooling. The air inlet and exhaust port should be placed on both sides of the computer room as much as possible, and the air flow direction should be from one side of the control box to the one side of the exhaust port. In addition, it should be considered that the exhaust gas generated during operation of the diesel engine also needs to be discharged.

There are many brands of generator sets on the market. Haixing Power reminds everyone to pay attention to the performance and quality of the selected units that must meet the requirements of relevant standards, as well as the actual load conditions, installation sites and power guarantee conditions of the places where the generator set is used. At present, my country and internationally have relatively detailed standards and regulations for generator sets in various application fields. Manufacturers must be able to present appraisal or certification certificates from national or international certification agencies. The current relevant standards for internal combustion engine generator sets in my country include: general GB2820-97 'Alternator sets driven by reciprocating internal combustion engines' (equivalent to international ISO8528), JB/T10303-2001 'Technical Conditions of Industrial Frequency Diesel Generators' of industrial frequency units, GB12786-91 'General Technical Conditions of Automated Diesel Generators' of automation units, etc. Relevant standards for relevant departments and industries are: GJB

Diesel generator sets used indoors are generally placed in a special computer room. In order not to cause noise pollution to the surrounding environment, noise reduction is required. According to Haixing Dynamics' summary, there are three common methods. The noise reduction in the computer room requires the treatment of the causes of noise separately. The main methods are as follows: 1. Inlet and exhaust noise reduction: The air inlet and exhaust passages of the computer room are respectively soundproofed walls, and soundproofing tapes are installed in the air inlet and exhaust passages. There is a distance in the channel for buffering, which can reduce the intensity of the sound source radiating from the computer room to the outside. 2. Control mechanical noise: The top and surrounding walls of the computer room are laid with a high sound absorption and sound insulation material, which is mainly used to eliminate indoor reverberation and reduce the sound energy density and reflection intensity in the computer room. To prevent noise from radiating outward through the door, arson soundproof iron door is installed. 3. Control smoke exhaust noise: smoke exhaust system

The use of coolant in diesel generator sets solves the problems of poor cooling of the generator set and excessive temperature of the machine parts, avoiding the occurrence of operational failure of the diesel generator set. At the same time, its anti-corrosion, rust and scale-proof effects also create an operating environment for the diesel generator set. Detailed explanation of the function of the coolant of the generator set: Antifreeze effect: When the temperature is too low, ensure that the diesel engine cooling system will not be frozen. Generally speaking, the antifreeze temperature of the commonly used coolant is that the freezing point is between minus 20 degrees to 45 degrees. It is reasonably selected according to the actual needs of different regions. Anti-boiling effect: Under high temperature conditions, the boiling point of the coolant is generally between 104 and 108 degrees. When the coolant is added to the cooling system and pressure is generated, its boiling point will be higher. Anti-corrosion effect: Special coolant can reduce corrosion to the cooling system, thereby avoiding water leakage caused by rust of the cooling system. Anti-rust effect: coolant can

Although summer has not yet entered, the temperature has risen significantly in recent days. Many friends have begun to dress up short-sleeved and shorts. The temperature is getting hotter. The use of generator sets in high-temperature environments is a common issue, which has triggered discussions. Haixing Power reminds that before the official operation, please understand the content: 1. Before starting, check whether the circulating cooling water in the water tank is sufficient. If it is insufficient, add pure water to refille it. Because the heating of the unit is all done by water circulation to dissipate heat. 2. The high temperature weather is relatively stuffy and humid. Be careful not to affect the normal ventilation and cooling of the generator. The dust and dirt in the ventilation channel should be cleaned frequently to keep it unobstructed. The generator set should not operate in a high-temperature environment to prevent the generator set from heating too quickly, causing failure. 3. After the generator set is continuously running for 5 hours, the generator should be shut down for half an hour to let the generator rest.

According to Haixing Power's summary, the diesel generator set failures and losses caused by neglecting safety prevention, and the safety hazards brought about by irregular operation of equipment are very high. Remind users to read the safety usage specification guidelines several times, so as to avoid some safety hazards. The following are the safety usage specifications for diesel generator sets that everyone needs to pay attention to: 1. Pay attention to the danger of electric shock. The power of the generator set must pass through a mechanically linked conversion switch to ensure separation from the mains. When it is necessary to connect to the grid with the municipal power supply, it must be approved by a professional department (power supply bureau) and special equipment for grid connection is used. Otherwise, there will be serious equipment and personal accidents. The unit must be reliable grounding, use insulation tools to repair live equipment, and pay attention to the danger of electric shock in humid environments. Comply with all electrical regulations,

During the operation of the generator set, many customers have observed abnormal smoke from the equipment. Here, Haixing Power technicians have compiled analyses of the corresponding faults for three types of smoke from the abnormal smoke from the generator set and shared them with you. I hope that you can master the self-test of this common problem fault through the following introduction. (I) Black smoke copyright by: www.hxdlkj.com Diesel is a complex hydrocarbon compound. Unburned diesel sprayed into the combustion chamber is decomposed at high temperature to form carbon black. When exhaust gas is exhausted, black smoke is formed. Black smoke is a manifestation of incomplete combustion of fuel in the combustion chamber. The main influencing factors are as follows: 1. After the piston ring, cylinder liner, etc. wear, the piston ring and cylinder liner are worn, the compression pressure is insufficient, causing the normal proportion of the mixture to change at the end of the compression stroke, causing the fuel to burn under an oxygen-free conditions and produce carbon deposits.
