Generator sets used outdoors often encounter rainy weather. If protective measures are not taken, the generator set can easily get caught in the rain. If it is not repaired and cared for in time, it will soon be rusted, corroded, and damaged. Appropriate maintenance methods can be selected according to the degree of rain exposure of the unit. Jiangsu Haixing Power Technology Co., Ltd. summarized the 'Maintenance Measures for Outdoor Generator Sets after Rain' to help customers solve problems. 1. Rinse the surface of the diesel engine with water to remove dirt and debris, and then use metal cleaner or washing powder to remove oil stains on the surface. 2. Support one end of the diesel engine so that the oil drain part of the oil pan is at the lowest position. Unscrew the oil drain plug and pull out the oil dipstick to allow the water in the oil pan to flow out on its own. When it reaches the point where the oil is about to be drained, the oil should be drained slightly. Let some of the oil and water drain out together and then tighten the oil drain plug. 3. Remove the air filter of the generator set, remove the filter upper shell, take out the filter element and other components, remove the water in the filter, and use metal cleaning agent or diesel

Butter (lubricating oil) is widely used in diesel engines. It can protect the engine body, but it cannot be abused, otherwise it will have adverse consequences and even be counterproductive and damage the engine body. Butter can lubricate and prevent corrosion, but Haixing Power Technology Co., Ltd. is here to tell you that some parts of the diesel generator set are not suitable for coating with butter. 1. Applying butter to the dry cylinder liner of the diesel generator set will cause the diesel engine to overheat and affect normal operation. The reason is that when the engine heats up to normal temperature, the cylinder liner will expand due to heat, and the cylinder seat hole will have a lower temperature due to the action of cooling water, so the expansion will be smaller. The outer surface of the dry cylinder liner is close to the seat hole to conduct heat dissipation. Grease on the surface of the cylinder liner prevents good contact between the two surfaces and prevents normal heat dissipation. 2. Apply butter to the cylinder head and cylinder gasket to enhance sealing. After the cylinder head nut is tightened, part of the butter will be squeezed out of the cylinder and wasted, and part of the butter will be squeezed into the cylinder. when diesel engine

Similar to human bone joints, the 'piston rings' of the generator set are divided into gas rings and oil rings according to their functions. They have the following functions.Piston rings are the parts that move in three directions among all engine parts.(i.e. axial movement, radial movement and rotational movement in the circumferential direction), and it is also the most demanding part in use conditions.At the moment of explosion in the engine combustion chamber, the gas temperature can reach 2000℃-2500℃, and its explosion pressure reaches an average of 50kg/cm2. The temperature of the piston head is generally not lower than 200℃.The piston makes reciprocating motion, and its speed and load are very large.Therefore, piston rings work under high temperature and high pressure conditions.Especially the first gas ring has the highest temperature and the worst lubrication conditions. In order to ensure that it has the same or higher durability as the other rings, the working surface of the first gas ring is often porous chrome plated. deal with.The porous chromium plating layer has high hardness and can store a small amount of lubrication.

[Brief Description] The engine valve mechanism is an important part of the entire valve system. Its function is to ensure that the engine can inhale as much gas mixture or air as possible during the intake stage while the engine is working, and to reliably seal during the engine compression and power stages. Because the valve mechanism withstands the high temperature from engine combustion and is cooled by the intake air,

The valve of the diesel generator set will make abnormal noise, and many customers are at a loss to do anything about it, so that everyone can perform self-inspection of the generator set and find the problem in time. There are various abnormal noises produced when the unit is running, and the valve can be adjusted according to the conditions. When running a diesel generator set, the characteristics and solutions of abnormal valve noise are as follows: Abnormal: The valve leaks and the sound is outside the valve chamber, which is more obvious at high load and low speed. The sound increases with the increase of load; Reason: The valve is reamed When seated, due to improper operation or excessive wear of the inner hole of the valve guide, the valve seat is skewed or the valve clearance is small, resulting in valve ablation, resulting in loose valve closing and air leakage noise. Treatment method: Remove the cylinder head, grind the valve, check the elasticity of the valve spring, and readjust the valve clearance. Abnormality: When the engine is running at idle speed, there is a continuous knocking sound between the tail end of the valve stem and its driving part, which becomes stronger as the rotational speed increases. The sound does not change when the engine temperature changes or the engine fires off. Reasons: 1.

The fuel injector is an important component of the generator set. A device that atomizes oil to adapt it to combustion requirements. This is the function of the fuel injector. However, the control of fuel injection volume and clogging cleaning are problems that many customers are concerned about. Jiangsu Haixing Power will answer them one by one.

Companies that use generator sets often find problems with carbon brushes (electric brushes) in their sets, which causes production instability for many customers. They have contacted Jiangsu Haixing Power for its after-sales response many times. Multiple safety reports have continuously reported several large-scale generator set shutdown accidents caused by carbon brush or rotor collector ring failures, causing large economic losses to the company. When a fault occurs during the operation of the carbon brush that introduces and exports current, everyone needs to think carefully about how to identify the type and nature of the fault so as to eliminate the fault as soon as possible and ensure the stable operation of the equipment. In fact, if the carbon brushes of the operating generator set are properly maintained and used, they will not cause problems. Nowadays, it is often reported in the news that large generator sets have shutdown accidents caused by carbon brush or rotor collector ring failures, causing large economic losses to enterprises. How to eliminate faults and ensure stable operation of equipment is a matter of concern to everyone. Haixing summarized the previous experience and provided some information for your reference.

The fuel injection pump of the generator set is the main component of the fuel supply system. Its working condition will directly affect the power, economy and reliability of the diesel engine.With the help of existing information and practical experience, Haixing Generator has summarized the following 'Ten Points' for correct maintenance of the fuel injection pump for your reference.Proper maintenance is an important prerequisite to ensure the normal operation of the fuel injection pump and extend its service life.1. It is necessary to properly use and filter diesel fuel to ensure that the diesel fuel entering the fuel injection pump is highly clean.Generally speaking, diesel engines have much higher filtration requirements for diesel than gasoline engines for gasoline. When using, diesel of a grade that meets the requirements must be selected and must undergo at least 48 hours of sedimentation.Strengthen the cleaning and maintenance of the diesel filter, clean or replace the filter element in time; clean the diesel tank in time according to the operating environment conditions, and remove the sludge and moisture at the bottom of the tank. Any impurities in the diesel will damage the fuel injection pump plunger and oil delivery valve. Couplings and transmission components cause severe

The casing of the generator set is also the machine body. It is a box made of gray cast iron material. It withstands various internal and external loads and the influence of the external environment during operation. Although the generator set body is very strong, many problems will still occur after long-term use. Therefore, Jiangsu Haixing Power provides several forms of body damage and simple repair methods below. 1. Being cracked by freezing in cold weather. This is the most common damage to diesel engines in winter. Cracks in the body can only be repaired by cold welding in parts that are not stressed. First, drill anti-crack holes at both ends of the crack, then plant a number of iron nails along the crack, and then use several pieces of patching plates perpendicular to the direction of the crack, and use low-carbon steel welding rods to weld firmly along the crack and patching plate. Pay attention to tapping the welding seam lightly with a small hammer while welding, and then correct it with a flame after all welding is completed. 2. The 205 bearing holes at the upper and lower balance shaft ends are worn. This situation must be repaired immediately. When the bearing hole is lightly worn, it can be repaired by enlarging the 205 bearing outer circle.
