Description

Technical Field

[0001] The present application relates to the field of diesel generator sets, and more particularly, to a cooling water preheating device for a diesel generator set. Background Art

[0002] A diesel generator set is a power supply device that uses a diesel engine as a prime mover to drive a synchronous generator to generate electricity. It is a power generation device with rapid startup, convenient operation and maintenance, low investment, and strong adaptability to the environment. Currently, the cooling water preheating device for diesel generator sets has low cooling water preheating efficiency. When the engine stops, the preheater preheats the cooling water. Using the principle of convective heat transfer and through natural circulation, the water temperature of the cooling water inside the engine is maintained at a certain level to improve the lubricity of the engine and prevent soot caused by incomplete combustion. However, using convective heat transfer and natural circulation for preheating will prolong the preheating time and reduce the preheating efficiency.

Specifically, the first partition plate 231 and the second partition plate 234 are respectively fixedly connected to the inner wall of the preheating cylinder 210 by welding.

The space between the first partition plate 231 and the second partition plate 234 is communicated with one end of the water guide pipe 130 through the water inlet pipe 250. The space between the first partition plate 231 and the second partition plate 234 is communicated with the other end of the water guide pipe 130 through the water outlet pipe 260. The first partition plate 231 and the second partition plate 234 are used to divide the space in the preheating cylinder 210, so that the cooling water is in the space surrounded by the first partition plate 231, the second partition plate 234 and the preheating cylinder 210.

[0043] In some specific embodiments, the electric heating plate 220 and the second temperature sensor 235 are located in the space between the first partition plate 231 and the second partition plate 234.

The electric heating plate 220 can heat the cooling water between the first partition plate 231 and the second partition plate 234. When the second temperature sensor 235 detects that the cooling water is heated to the set temperature, turn on the motor body 232 through the control panel 160. The motor body 232 will drive the spiral blade 233 to rotate, and the spiral blade 233 will cause the cooling water to move from right to left. The cooling water flows into the water guide pipe 130 along the water outlet pipe 260. The cooling water in the water guide pipe 130 preheats the generator set body 110 through the heat conducting plate 120. At the same time, the residual heat in the preheating cylinder 210 preheats the generator set body 110 through the heat pipe 140 and the heat conducting plate 120. The cooling water then enters the water guide pipe 130 through the water inlet pipe 250 for circulating heating. When the first temperature sensor 170 detects that the generator set body 110 is preheated to the set temperature, turn off the motor body 232 and the electric heating plate 220 through the control panel 160, and the preheating ends. Thus, the purpose of high preheating efficiency of the cooling water preheating device for cooling water is achieved. By actively preheating through the water cycle, the internal of the engine can be quickly circulated for preheating, reducing the preheating time and improving the preheating efficiency.
