When using a generator set, have you ever paid attention to the starting battery section? How should it be charged and how should normal maintenance be performed? Next, let Haixing Power, an experienced generator set manufacturer, analyze this operation in detail for everyone. Correct charging method is very important, it is the basic condition to ensure the service life of the battery. It is recommended to use the original charger as much as possible, because the charger matches the configured battery. The supplementary current, maximum charging voltage and conversion current, float voltage, float current, etc. are all determined in advance, and the parameters of other chargers may be different, resulting in a mismatch with the battery being charged, which not only affects the charging effect, but also It will also affect the battery life. Let’s talk about the charging environment. Choosing a suitable charging environment is very important. A certain amount of heat is often generated during battery charging, so it is recommended to charge the battery in an open and ventilated place.

Recently, many customers have been consulting the staff of Haixing Power on how to establish a good management system for the generator room. Haixing believes that customers and friends should start from the operation of the generator set, determine the specific responsibilities of the operators, and take various safety measures. Let us take a look at the detailed introduction of these aspects. 1. Operation management system 1. The door of the generator room should be locked at all times, and the key is managed by the squad leader. Non-staff members are strictly prohibited from entering without the approval of the department leader. 2. The person on duty must be familiar with the basic performance and operation methods of the diesel generator, and should conduct regular inspections. 3. The engine oil level and cooling water level of the diesel generator should be checked frequently, the oil reserve in the diesel tank is sufficient, and the battery voltage and electrolyte specific gravity are normal. 4. The generator runs without load once every Monday and is operated by the day shift personnel.

Many customers are very concerned about the troubleshooting of generator sets in their consultations. Haixing Power's technical staff will talk to you about the principles of troubleshooting. Focusing on these principles, we can reasonably carry out troubleshooting of generator sets so that the equipment can be restored as soon as possible. normal operation. 1. Judgment of faults must be based on overall analysis, and troubleshooting must be comprehensive. The systems, components, and parts of a diesel generator set are closely related. If one component, system, or part fails, other systems, components, or parts will inevitably be involved. Therefore, a fault phenomenon cannot be viewed in isolation, but the fault must be analyzed as a whole and the fault must be eliminated in a timely manner. 2. When finding faults in the diesel generator set, disassembly should be minimized. When troubleshooting, you cannot blindly disassemble the components of the diesel generator set. You must first understand the structure, working principle, fault location, etc. of the diesel generator electronic components before disassembly. Only after disassembly

The ambient temperature has an impact on the use of the generator set. Now that the cold season is gradually entering, Haixing Power reminds everyone: prepare antifreeze in advance and add antifreeze in time! Antifreeze is of great significance to the operation of the generator set 1. Antifreeze When the indoor and outdoor temperatures are too low in winter, in order to ensure that the cooling system of the diesel generator is not frozen, generally speaking, the antifreeze temperature of the commonly used generator antifreeze is also That is, the freezing point is between minus 20 degrees and 45 degrees above zero. It is often reasonably selected according to the actual needs of different regions to meet the use requirements of Cummins generators. 2. The anti-boiling diesel generator ensures that it will not boil prematurely under high temperature conditions. The boiling point of commonly used antifreeze is 104 to 108 degrees. When the antifreeze is added to the cooling system and generates pressure, the boiling point will be higher. 3. The special antifreeze for anti-corrosion generator sets can reduce corrosion to the generator cooling system, thereby reducing the risk of rust in the cooling system.

The generator set has a longer period and more regular fast and slow phenomena in the low and medium speed range. This is the result of the speed regulation response lagging too much behind the actual speed change. The main reasons are as follows. The internal lever of the speed regulator is loose due to wear of the connecting pin hole. Copyright by: www.hxdlkj.com In this case, the two-way speed regulation movement of increasing or decreasing the oil supply produces excessive direction change lag. When the engine is working, the speed control response will inevitably lag behind the actual speed change, but the lag cannot be too large, otherwise a large adjustment amplitude will occur. The adjustment amplitude is too large, that is, when the speed has increased or decreased due to the increase or decrease in fuel supply, the fuel will continue to be increased or decreased. Until the speed exceeds the adjustment range of the speed regulator, its strong feedback signal will not pass through the speed governor. To realize the reaction of reverse regulation, the speed regulation reaction exceeds the predetermined range, causing the speed to

Although the temperature has gradually dropped, the abnormal temperature of the generator set still needs to be paid attention to. As one of the questions frequently asked by customers, how does the abnormal high temperature failure of the generator set occur? Let’s take a look at the cause analysis by Haixing Power technicians. Only by identifying the cause can we take effective countermeasures. The reasons for the high temperature of the generator set are as follows: 1. Long-term overload operation of the diesel engine will increase its fuel consumption and heat load, resulting in excessive water temperature. For this reason, long-term overload work should be avoided. 2. Insufficient coolant If there is a lack of coolant in the diesel engine cooling system, it will affect the heat dissipation effect of the diesel engine and cause the diesel engine to be overheated. In this regard, the coolant stock in the radiator and expansion tank should be checked frequently and replenished in time when the liquid level is low. 3. Poor coolant circulation and insufficient thermostat opening will reduce the

Friends who often operate generator sets know that the piston ring is one of the vulnerable parts of the generator set, and the sound is an obvious sign of failure. So today we will follow Haixing Power to learn: What faults correspond to the abnormal sound of the piston ring part of the generator set? question. Haixing Power selected three representative sound faults: (1) Metal knocking sound of piston rings. After the engine has been operating for a long time, the cylinder wall is worn, but the upper part of the cylinder wall that is not in contact with the piston ring almost maintains the original geometric shape and size, which creates a step on the cylinder wall. If an old cylinder gasket is used or a new one is too thin, the working piston ring will collide with the cylinder wall step, making a dull 'puff' metal impact sound. If the engine speed increases, the abnormal noise will also increase. In addition, if the piston ring is broken or the gap between the piston ring and the ring groove is too large, it will also cause a loud knocking sound.

The temperature suddenly dropped a lot. Are you not used to it? While we are dressing ourselves to protect ourselves from cold and heat, we should also not forget to pay attention to the influence of ambient temperature when using the generator set. Haixing Power reminds everyone to pay attention to seven taboos when using generator sets. One avoidance is to release water too early or not to release cooling water. Run at idle speed before turning off the engine. Wait until the cooling water temperature drops below 60°C and the water is not hot to your hands. Then turn off the engine and drain the water. If the cooling water is released prematurely, the body will suddenly shrink and crack when it is suddenly attacked by cold air when the temperature is high. When draining water, the remaining water in the body should be drained out to prevent it from freezing and expanding, causing the body to burst. Second, avoid using fuel randomly. The low temperature in winter makes the fluidity of diesel oil deteriorate, the viscosity increases, and it is difficult to spray, resulting in poor atomization and worsening combustion, resulting in a decrease in the power and economic performance of the generator set. Therefore, light diesel oil with low freezing point and good ignition performance should be used in winter. Generally require diesel

I believe that many users of diesel generator sets have such doubts. I have done every maintenance and repair. Why does the equipment still fail frequently or its lifespan is not long? According to the summary of Haixing Power’s interactions with customers over the years, this is actually largely related to everyone falling into misunderstandings about maintenance and neglecting some small details. To sum up, we only did XXX and ignored XXX. Let's take a look at some easily overlooked points in maintenance: 1. Only replace the plunger and oil nozzle, ignoring the technical status of the oil delivery valve. After the oil delivery valve is worn, the residual pressure in the high-pressure oil pipe will be too high, causing the fuel injector to cut off the oil and drip oil, causing the diesel engine to smoke from the exhaust, knock the cylinder, and run unstable. The method is to check the oil outlet valve and use a pressure gauge with a range of 0-600 kg/cm². When the gauge needle drops from 200 kg to 180 kg/cm², the pressure holding time should be greater than 15 seconds, otherwise it should be replaced.

Will the diesel generator be damaged if it is left idle for a long time? This statement has puzzled many users. Haixing Power will tell you in detail why the diesel generator set 'stops'. copyright by:www.hxdlkj.com The filtration capacity of the filter decreases. The filter plays a role in filtering diesel, engine oil or water to prevent impurities from entering the body. Oil dirt and impurities are also inevitable in diesel, so during the operation of the unit, the filter Played an important role, but at the same time these oil or impurities The impurities will be deposited on the filter wall, which will reduce the filtration capacity of the filter. If there is too much deposition, the oil circuit will not be smooth. In this way, when the oil machine is running under load, it will go into shock due to the inability to supply oil (like a person lacking oxygen), so During the normal use of the generator set, it is recommended that: first, every 500 Replace three filters every hour
