The cooler is the most commonly used heat exchange equipment in the heating system.

The cooler is the most commonly used heat exchange equipment in the heating system, and its operation directly affects the quality of external heating. The analysis of the causes of the problems in the operation of the cooler is of great significance to the safe operation, energy saving and consumption reduction of the heat exchange station. A problem encountered in the operation of the system throughout the heating season, the main problem is the lack of heat transfer peak heater. The cooler is installed on the bypass of circulating water supply and adopts double-grain tube cooler. Its design parameters are: flow rate G = 1500 t/h, heat exchange area F = 170 m2, design steam inlet parameter t = 180 ℃,P = 0.2MPa, and circulating water inlet and outlet

Technical progress and application of new high efficiency cooler

Technical progress and application of new high efficiency cooler

Introduction Due to the limitation of manufacturing process and technical level, the early cooler can only use simple structure, small heat transfer area, large volume, heavy, such as snake tube cooler. However, with the development of manufacturing technology, shell and tube coolers have gradually appeared. The unit volume of this cooler has a large heat transfer area and good heat transfer effect. It has become a typical cooler in industrial production for a long time. In the 1920 s, plate coolers appeared again. Coolers made of plate tube have compact structure and good heat transfer effect. There are many kinds of traditional coolers, and there is no unified division method. At present, the main

Selection and Installation of Cylinder Liner of Diesel Engine

Selection and Installation of Cylinder Liner of Diesel Engine

Most diesel engines use thick-walled wet cylinder liners, which are sealed and installed in the cylinder block by a water blocking ring, and form a cooling water cavity with the inner wall of the cylinder block. The inner surface of the cylinder liner is an integral part of the combustion chamber and is the place where the piston compresses the gas to do work. The outer surface of the cylinder liner is in contact with the cooling water for a long time and is easily damaged by cavitation and electrochemical corrosion; the inner surface is directly affected by the high temperature, high pressure and corrosion of the gas, and the relative movement side thrust and strong friction with the piston assembly. Wear, scratches and fine cracks occur on the surface of the cylinder. Therefore, the cylinder liner is a vulnerable part. When the engine is overhauled, the technical status of the cylinder liner should be tested in time

What causes diesel engine cylinder liner to break

What causes diesel engine cylinder liner to break

Diesel engine cylinder liner fracture analysis: cylinder liner cracks in the use of the failure occurs from time to time, usually the cylinder liner cracks in the longitudinal shape. Starting from the cylinder liner flange (in the case of a 6105 diesel engine), it extends below the piston ring movement area. Some cylinder liner cracks (take 4135 as an example) start from below the cylinder liner flange and pass through the cylinder liner flange section to the upper part. In addition to the cylinder liner will produce local fracture failure, to 490 diesel engine, for example, sometimes there will be "brush table" accident. That is, at the upper shoulder of the cylinder liner, a neat fracture occurs. Take out the broken cylinder liner, and it can be seen that the fracture is on the shoulder and the upper part of the cylinder liner.
