Diesel Engine Hydraulic Tools
Diesel Engine Hydraulic ToolsDiesel engine hydraulic tools are tools used to maintain and repair diesel engines. It can help engineers deal with various problems more efficiently during maintenance and improve work efficiency. When purchasing diesel engine hydraulic tools, the following requirements need to be met. First of all, diesel engine hydraulic tools need to have stable working performance. This is because diesel engine hydraulic tools need to withstand high pressure when used. If unstable tools are used, it is easy to cause damage to the machine and cause personal injury. Therefore, you need to choose high-quality hydraulic tools that have undergone rigorous testing when purchasing.Second, diesel hydraulic tools need to have good durability. In the process of maintaining diesel engines, engineers often need to use these tools for disassembly, installation and adjustment. If the hydraulic tools of diesel engines are easily damaged or fail, it will affect the smooth progress of the maintenance process. Therefore, hydraulic tools with higher quality and better materials should be selected to ensure that they can work stably for a long time.Third, diesel engine hydraulic tools need to be small and flexible. The internal structure of the diesel engine is relatively complex and compact, so it is often necessary to use small hydraulic tools to complete the task during maintenance and maintenance operations. Small and flexible hydraulic tools need to have high maneuverability and flexibility, and at the same time need to be easy to operate, so as to bring higher efficiency.Finally, diesel hydraulic tools need to have good safeguards. In the process of using hydraulic tools, unexpected situations are sometimes encountered, such as sudden power failure, accidental input of substances, etc., so it is necessary to provide protection for the safety of workers. Therefore, when purchasing diesel engine hydraulic tools, be sure to choose those products with safety protection measures and emergency shutdown devices to ensure the safety of workers and the reasonable operation of equipment.To sum up, diesel engine hydraulic tools need to meet multiple requirements such as stability, durability, compactness and flexibility, and complete safeguards. When purchasing, the invested funds also need to correspond to the quality and performance of the tool, so as to ensure the purchase of the most suitable hydraulic tools, improve the maintenance efficiency of diesel engines, and reduce the labor intensity of engineers.

Spare parts list DetailCylinder Crane Operation Of Marine Diesel Engine
Cylinder Crane Operation Of Marine Diesel EngineWith the use of small size, high power, high cooling circulating water temperature and high-quality sealant in modern ship mainframes, the working cycle of hanging cylinders and pulling cylinder liners is greatly extended.This is very beneficial to improve the power and safety of ships, and is an inevitable trend to reduce operating costs and improve economic benefits.But it also brings new issues and new requirements to maintenance managers.Analysis of the Reasons for Difficulty Opening the Cylinder HeadAs long-stroke DC scavenging type models are widely used at present, most models, especially MAN models, have the cylinder head inserted into the upper part of the cylinder liner, and the seal between the cylinder head and the circulating cooling water of the cylinder liner is made by special rubber To be done.In order to increase the reliability of the seal, the clearance between the cylinder head and the sealing surface of the cylinder liner should be as small as possible.As long as the safety regulations for the maximum expansion coefficient can be met.Under normal circumstances, there is no difficulty in lifting the cylinder and pulling the cylinder liner.However, due to some reasons (such as not testing according to the requirements, putting water treatment agent; sometimes encountering the backflow of seawater into the cooling system, such as the failure of the heat exchanger of the water generator, etc., the quality of the water will be poor. High water quality; poor water quality in some port areas, etc.), can make the cooling water in the system, especially in the small gap, large thermal conductivity, high water temperature, precipitation of solid sludge, scale and other substances.It is especially serious in the sealing section between the cylinder head and the cylinder liner of the main engine, and the cylinder liner and the cylinder block.Because the gaps in these places are small (some models are only tens of wires), the heat transfer there is faster and the relative temperature is higher, so there are more solids precipitated in the circulating water.It is tightly wrapped with the sealing order. In addition, since the circulating water there is relatively static, it is the accumulation place of solid sediments.Over time, the sediment will accumulate more and more, which will not only affect the heat dissipation, but also make the sediment harden, and also cause the premature aging of the rubber seal, which will gradually lose its elastic force, which will cause the cylinder head to be opened when the cylinder is lifted. , pulling the cylinder liner, etc. to increase the resistance, making it difficult to open the cylinder head, especially on some old ships and ships with poor management.Under normal circumstances, there is no difficulty in lifting the cylinder and pulling the cylinder liner.However, due to some reasons (such as not testing according to the requirements, putting water treatment agent; sometimes encountering the backflow of seawater into the cooling system, such as the failure of the heat exchanger of the water generator, etc., the quality of the water will be poor.
