Debugging methods for 80KW emergency diesel generator

Do you know how to debug 80kw emergency diesel generator? Today Starlight Power tell you the ways. After finished to assembly 80kw emergency diesel generator, before debugging, we should inspect the genset clearly.   The inspection step is as follows: 1.Check whether the surface of the unit is clean; whether the anchor nut, flywheel screw and other moving machine nut are loose, and the problem is promptly tightened. 2.Check whether the clearance of each part is correct. In particular, carefully check whether the clearance of the pressure reducing mechanism of each inlet and exhaust valve meets the requirements. 3.Put each cylinder in the decompression position, turn the crankshaft to check whether the sound of each cylinder is running abnormally, and whether the crankshaft rotates freely, and pump the oil into a friction surface. Then close the pressure reducing mechanism, shake the crankshaft, check if the cylinder is leaking. If the crankshaft is shaken, it feels very laborio...

Introduction of Full Copper Brushless Generator

There are many brands of generators on the market. Because the materials are different, the price difference of generators is very large. When customers choose   diesel generator sets   as backup power, should choose full copper brushless generator, some bad manufacturers use semi-copper semi-aluminum or aluminum wire generators to directly sell to the customer. Before purchasing, the customer must ask supplier the material of the generator. Why should we choose a full copper brushless generator? Briefly, the movement of the generator is mainly used for electrical conduction, and the conductivity of the metal material is better. Let's take a look at the reference value of metal conductivity: Silver: 100%; copper: 99%; gold: 76%; iron 74% From these values we can conclude that silver and copper are more suitable for electrical conduction. But the price of silver is relatively high, so copper is the perfect movement for the generator. Therefore, in selecting the alt...

Volvo Diesel Generator Fails to Produce Specified Power

When Volvo diesel generator is failure to produce specified power, firstly we should check whether air intake and fuel injection are sufficient, whether the combustion process is normal and the compression pressure is large enough to analyze and judge step by step, find out the cause of the fault and eliminate it. The specific causes and solution methods are as follows: 1.Failure to produce specified power due to failure of valve mechanism and air inlet and exhaust system. Reason: Incorrect clearance between intake, exhaust valves and rocker arms; Incorrect actual opening and closing time of intake and exhaust valves; Valve spring is damaged; The valve has carbon deposits and the sealing surface leaks; Air filter blocked; Exhaust pipe and silencer have serious carbon deposits and poor exhaust. Treatment methods: Check and adjust to specified clearance; Check and adjust the opening and closing time of intake and exhaust valves; Replace new valve spring; ...

What Causes Power System Overvoltage

Overvoltage refers to the phenomenon that the rms value of the AC voltage rises at the power frequency, exceeding 10% of the rated value, and the long-term voltage fluctuation phenomenon lasts longer than 1 minute; the occurrence of overvoltage is usually the result of load switching. Occurs when the inductive or capacitive load is turned on or off during normal use. The abnormal voltage rise over the working voltage in the power system under certain conditions belongs to a kind of electromagnetic disturbance phenomenon in the power system. The insulation of   electrical equipment   is tolerant to the operating voltage for a long time, and must be able to withstand a certain range of overvoltage, so as to ensure the safe and reliable operation of the power system. Overvoltage is divided into external overvoltage and internal overvoltage. External overvoltage is also called lightning overvoltage and atmospheric overvoltage. Caused by the discharge of thunderclouds ...
