Starlight generator

The compression ratio of diesel engine is the ratio of the total cylinder volume to the combustion chamber volume. The change of the compression ratio not only affects the power and economy of the diesel generator, but also affects its start-up performance. Each diesel engine is designed with an optimal compression ratio, but in use, the compression ratio is often reduced due to the influence of various related factors. The main reasons for the reduction of the compression ratio of the diesel engine and some problems that should be paid attention to in the course of maintenance are summarized as follows ： I The piston is low at the end of compression 1. The matching clearance of related parts is too large. When the clearance between the crankshaft main bearing and the main journal, the connecting rod bearing and the connecting rod journal, the connecting rod bushing and the pin sear hole is too large =, during the compression process, the actual position of t...

When we purchase and select diesel generator sets, they often confuse the relationship and definition between apparent power, active power,  rated power, maximum power and economic power. For this reason, we have sorted out the relationship between them so that everyone can understanding. 1. The unit of apparent power is KVA, which is used to express the capacity of transformers and UPS. 2. The active power is 0.8 times the apparent power, and the unit is KW. It is used to power generation equipment and electrical equipment in China. 3. The rated power of a diesel generator set is the power that can be continuously operated for 12 hours. 4. The maximum power is 1.1 times the rated power, but only 1 hour is allowed within 12 hours. 5. The economic power is 0.75 times of the rated power, which is the output power of the diesel generator set that can be operated for a long time without time limit. When this power is runnin...

After purchasing the diesel generator set, users should pat attention to safety when using it. Especially when the generator set is just stopped, do not unscrew the radiator cover to fill or replace the coolant. Otherwise, the high temperature cooling water will cause serious burns. The genset is shut down and the diesel engine is completely cooled. The operation and precautions of the diesel generator set after shutdown are explained in detail below. 1. Shutdown operation of diesel generator sets Receive a signal to ready to disassemble and perform a deceleration unloading. After unpacking, the machine gradually slowdown and cool down, and listen to the machine for any noise and determine its location and cause to stop. 2. The fuel pump is turned off normally (in special causes, faulty or emergency stop can be used), and the external circulation pump is turned off. 3. Brakes must be carried out when parking for more than 1 hour. 4. After parking, perform genset m...
