Wear and Repair of Diesel Generator Shell Cracks
Browse: Release Date: 2019-11-26
Wear and Repair of Diesel Generator Shell Cracks
Diesel generator refers to a power machine that uses diesel and other fuels and uses a diesel engine as a prime mover to drive a generator to generate electricity. The entire unit is generally rented out by diesel engines, generators, control boxes, fuel tanks, starter and control storage batteries, protection devices, emergency cabinets and other components.
Among them, the shell is an important component, which mainly resists the external load by the mid-surface stress uniformly distributed along the thickness, rather than the bending stress that varies along the thickness. This internal force characteristic of the shell allows it to make fuller use of the material strength than a flat plate, and thus has a greater bearing capacity. In water conservancy projects, the shell is widely used, such as the rental of generators such as double-curved flat-shell gates and arch dams.
Wear and Repair of Diesel Generator Shell Cracks
Therefore, the wear and tear of the shell of the diesel generator is relatively troublesome, and the generator rental below will explain the cause and repair based on the specific situation.
I. Causes of Diesel Engine Shell Cracks
1. Manufacturing defects:
Diesel engine housings are usually castings. It is inevitable that some pores and trachomas or cracks due to stress will be generated during the casting process. These manufacturing defects will be gradually enlarged during the later use, eventually leading to leakage and being found;
2. Reasons for use and maintenance:
When the diesel engine is running in winter, it is necessary to add antifreeze to cool the circulating water or release the cooling water in time when the engine is stopped. Once the cooling water freezes during shutdown, it will be extremely easy to cause the shell to be frozen and cracked, causing water leakage and unusability; generator rental
3. Cracks caused by other reasons.
Cracks in the shell of a diesel generator
1. Repair principle:
Soleil carbon nanopolymer materials have excellent adhesion and mechanical strength, can withstand certain pressures, and are not easy to fall off. At the same time, they are resistant to chemical corrosion. Therefore, applying Soleil carbon nanopolymer materials to cracks can effectively Avoid cracks and leaks. Before crack treatment, it is necessary to do effective crack arrest work to avoid further extension of the generator rental.

2. Technical advantages of Soleil carbon nano-polymer materials
(1) Low comprehensive repair cost: for external cracks, online repair can be realized;
(2) Less labor input: It is not necessary to dismantle the equipment in large quantities to ensure operating space;
(3) High efficiency: generally complete the repair in 6 hours, and realize the startup operation;
(4) Long service life: On the premise of normal maintenance of the equipment, as long as the repair site is not dismantled or damaged artificially, its service life completely reaches or exceeds the service life of the new components
3. Construction Standard for Diesel Engine Shell Crack Treatment
(1) The surface is roasted with oil and polished to ensure that the surface is dry, clean and rough;
(2) Hitting crack holes to prevent further crack extension;
(3) Apply carbon nano-polymer material to achieve a certain thickness, and cooperate with carbon fiber to enhance the repair strength;
(4) It can be turned on and used after curing
4. On-site treatment of diesel engine case cracks Application case Generator rental.
