When the generator is connected to the network, the phases of the generator and the network are not completely synchronized at the time of connection to the network, since the network can be considered as an infinite network, the current in the network opposes itself . powers the generator, forcing the generator to The phase is synchronized with the grid, which is called pull-in synchronization in the terminology. At that time, the South African current will be generated in an instant. The greater the phase difference, the greater the inrush current. Therefore, manual operation to select the moment of connection to the network is very important.
Customers often ask us the same question: Will using tap water instead of coolant corrode the diesel generator water tank? Regarding the explanation of this problem, our generator Jiangsu Taizhou Dongkang Co., Ltd. specially organized atechnical team to lead a discussion:
Tap water replacement coolant for generator sets is generally divided into the following types: 1. Well water 2. Tap water 3, river water. Generally, the main condensable tap water in remote areas is well water, while most customers in urban areas use tap water. The trace minerals in tap water themselves will not corrode the water tank! The cause of corrosion of the generator set fan cooling water tank is an electrochemical reaction. If it is made of real 304, 316L stainless steel and copper, it will not be corroded at all. the nickel content is insufficient and it will be used for a long time without adding chlorine. Pure water can also corrode! The material of cooling water tank of national gold brand generator setsdinary is usually made of 202 and 304 stainless steel. Generally, manufacturers use genuine 304 stainless steel materials, while many unscrupulous manufacturers use 202 stainless steel. As mentioned above, genuine 304 stainless steel will not corrode when used with tap water. However, after a long time, the chloride ions in tap water will ionize and turn the stainless steel a dark color. If 202 is used, corrosion will occur after prolonged washing and soaking. Therefore, we recommend customers to use at least pure water or tap water. Customers who have conditions can use vehicle coolant directly.
