When the generator set is running, the operator will regularly check the status of the equipment and make relevant records. Among them, the problem of water pump bearing leakage is one of the common faults. Follow Haixing Power to learn how to troubleshoot this fault. This kind of failure is generally caused by damage to the water seal. The troubleshooting method for water pump bearing leakage is as follows: 1. Check the overflow hole on the fresh water pump housing. It is found that the overflow hole is blocked by a wooden rod. Use pliers to clamp it out and cool it. Water leaks from the overflow hole, and the bearing overflow phenomenon disappears. When the overflow hole is blocked by a wooden stick, the rotation of the water pump impeller generates pressure, which eventually causes the cooling water to spray out from the gap between the water pump bearings. When the wooden rod is taken out, the cooling water left in the water seal leaks directly from the overflow hole on the water pump housing. 2. After shutdown, the water seal was disassembled and inspected, and it was found that the water seal was damaged. After replacement, the leakage of the fresh water pump disappeared. Troubleshooting involves stopping

In the summer, Haixing constantly reminds everyone about the issues of heat dissipation and cooling water. In fact, the relationship between cooling water and seasons is not small. Let’s follow the staff to see how the cooling water changes with the seasons. copyright by:www.hxdlkj.com In winter, the temperature is low, the ambient temperature of the generator set is also low, and the temperature of the coolant will also be very low, so the temperature of the coolant of the generator set will rise slower. For example, the Cummins generator set will be most effective. At high power, the coolant temperature should be around 80°. Therefore, when using the generator set in winter, the water temperature standard is around 80°. The temperature in summer is relatively high, and in some areas there may even be high temperatures above 40°C. The temperature of the coolant of the generator set rises rapidly during such high temperature seasons. The generator set is likely to cause a cylinder accident when the water temperature is 100°C, so the generator set will be cooled when the coolant exceeds 95°C.

Sometimes many netizens will personify the generator set, and people rely on fresh air to survive. Does the generator set also put forward requirements for air? Haixing Power believes that such doubts may be related to the severe haze weather, and everyone will feel that the haze affects the operation of the equipment. In fact, this understanding is not unreasonable. Too many impurities in the air can not only harm people's health, but also cause failure and damage to diesel generator sets. The quality and circulation of the air play a decisive role in the diesel generator set, and we must pay attention to it during use. If the generator set is used indoors, we must ensure that there is enough fresh air. If the machine room is too tightly sealed, it will lead to poor air circulation, which will not only affect the diesel combustion rate of the diesel engine, but also reduce the cooling effect of the unit. The inlet cooling cannot be achieved, the heat generated by the unit cannot be discharged, and the temperature in the machine room will will gradually

When the generator set is running without a cylinder, abnormal noise, insufficient power, and jitter may occur. When the generator set is running, one or two cylinders do not work, but other cylinders function normally. What is the reason for this situation? ? The following is Haixing Power’s summary of the issuecopyright by: www.hxdlkj.com ① During cold starts in winter, due to the cold weather, some cylinders do not work at idle speed when starting for the first time every day. However, as the operating temperature increases, all cylinders gradually work normally; ② Due to excessive load, individual cylinders The piston ring in the cylinder is broken and the cylinder is pulled. Or a mechanical failure such as a loose valve seal causes the cylinder compression pressure to fall below the required level, causing the cylinder to not work; ③ Due to quality problems with the oil used by the user, the injector nozzle parts are clogged or stuck, causing the cylinder to not work. Fuel injection occurs, so the cylinder does not work; ④The fuel injection pump plunger and oil delivery valve malfunction, causing the cylinder to supply

The unstable voltage of the generator set may also be a common problem, and many operators have encountered such a situation. Haixing simply summarizes the reasons for this in six aspects that everyone needs to pay attention to. 1: The unstable speed of the diesel engine causes the voltage of the generator set to be unstable. 2: Damage to the voltmeter of the generator set causes the illusion of voltage instability. Of course, most generator sets now use smart displays, so this phenomenon no longer exists. 3: The generator set is prone to voltage instability if the load is too large. 4: Damage to the voltage regulator components of the generator set causes instability in the voltage of the generator set. 5: Poor circulation in the fuel pipe of the generator set causes unstable engine speed and unstable voltage. This can be attributed to point 1. 6: The unstable load of the equipment used will also cause the voltage of the generator set to be unstable. Generator set operation

Can the generator set be left alone after shutting down or stopping according to normal procedures? This is obviously inappropriate. After the generator set is connected, some follow-up operations are required to complete the entire shutdown process. What does the follow-up operation include? Haixing Power has summarized for everyone: Check whether the unit has 'three leaks' (lubricating oil, fuel, coolant);

The basic reasons for the power drop of diesel generator sets have been briefly discussed by Haixing before. Generally speaking, the power of the equipment will drop after being used for a period of time, but there will be no adverse conditions or symptoms. This is classified as a normal phenomenon. Haixing Power would like to emphasize that in addition to natural wear, air humidity, temperature and other factors affecting power, some parts of the generator set will also bring changes in power to the diesel generator set. The main reasons are: 1. The air filter is too large. If it is dirty, the air intake is not enough, the air filter must be cleaned or replaced. 2. The fuel filter device is too dirty, and the fuel injection amount is not enough, it must be replaced or cleaned. 3. The ignition time is incorrect and needs to be adjusted. High air temperature and high humidity will reduce the power of the diesel engine, and component problems will also reduce the power. To prevent such problems, the key is to rely on card maintenance. Timely maintenance and upkeep can not only improve the reliability of the equipment, but also There can still be

Netizens have a thorough understanding of the daily operation details, precautions, fault inspections and other aspects of the generator set by consulting the information on the official website of Haixing Power. In recent discussions, everyone has once again turned their attention to some preparations before operation. Haixing The staff believes that it is still necessary for everyone to come together and take a look at the nine routine inspections that need to be done before starting. Routine inspections before operation of the diesel generator set: 1. Appearance inspection: copyright by: www.hxdlkj.com Whether the outside of the engine of the generator set is damaged and complete, whether the screws are tightened, and whether the generator output line and control line are damaged or loose. 2. Fuel system: 1. Whether the amount of diesel is sufficient, whether there is any oil leakage or loose fittings in the wiring and piping, and remove the remaining air in the fuel system. 2. Lubrication system: Is the engine lubricating oil enough? new engine

Vibration faults in generator sets are very common, and Haixing Power has been exposed to them more often. According to daily experience, the causes of vibrations mostly come from the failure of internal components. We need to investigate one by one from the following aspects. 1. The shaft system of the linkage part is misaligned, the center lines do not coincide, and the centering is incorrect. The main cause of this failure is poor alignment and improper installation during the installation process. Another situation is that the center lines of some linkage parts are coincident in the cold state, but after running for a period of time due to the deformation of the rotor fulcrum, foundation, etc., the center lines are destroyed again, resulting in vibration. 2. The gears and couplings connected to the diesel generator set are faulty. This kind of failure mainly manifests as poor gear meshing, severe gear tooth wear, poor lubrication of the opposite wheel, skewed and misaligned couplings, incorrect tooth shape and pitch of the gear coupling, excessive clearance or severe wear, all of which will cause certain problems. vibration.

Frequent high-temperature weather in summer requires everyone to pay attention to the abnormal temperature of the generator set and also to prevent water outages. If you encounter a water outage during operation, how to take effective measures? Haixing Power will introduce to you: During operation, when the generator set's water cutoff signal is sent, the operator should immediately check the time and be prepared to deal with the accident if the water cutoff protection refuses to operate; at the same time, find out the cause and restore the water supply as soon as possible. If the cooling water is restored within 20S, a comprehensive inspection of the cooling system and various parameters should be carried out, especially the water supply of the stator coil. If the water flow is found to be blocked, the inlet water pressure should be immediately increased to restore the water supply or the train should be immediately decoupled and shut down; if the water cutoff time reaches If the water cutoff protection refuses to operate after 20 seconds, the generator circuit breaker and magnetic switch should be opened manually immediately.
