Diesel generator valve leakage will directly affect the engine’s working characteristics and economy of use. Therefore, generator rental and use of diesel generator valve leakage to cause high attention. The influence of diesel generator valve leakage is as follows:
Diesel generator valve leakage will cause engine cylinder leakage, fuel consumption increase, fuel combustion in the cylinder is poor, exhaust smoke or air filter gas, serious will make the engine start difficult, and even the engine work balance is damaged, the movement process often abnormal vibration.
Diesel generator valve leakage in high temperature air flow under the burning, the valve head and valve seat are soon ablated, so that the mechanical strength decreases, and then wear, deformation, make the leakage more serious and carbon accumulation, resulting in a vicious cycle.
If the exhaust valve leakage, and meets the exhaust pipe plugging formation poor exhaust, valve guide and duct clearance is too large, there will be a part of high temperature exhaust gas along the valve guide and valve guide clearance after flushing oil into the valve chamber, pollution valve chamber, the valve chamber, poor lubrication radial component temperature, adhesion formation, accelerate the gas generator equipping mechanism of wear and damage.
If the inlet valve leakage, leakage of cylinder in the process of compression, the compression temperature cannot make timing oil injection of spontaneous combustion, and some combustible mixture through the inlet valve leakage cracks in reflow inspiratory mouth, air inlet pipe, and then in the next cycle of the intake stroke to intake valve, when the working stroke and fuel injection constants in the cylinder, The accumulated fuel and combustible mixture will burn, causing the engine to work rough and knock.
If the multi-cylinder engine, when the inlet valve of a cylinder leaks, the combustible mixture or exhaust gas flowing backwards into the intake pipe will be sucked into other cylinders, so that the work of other cylinders is also affected.
Diesel generator after valve leakage problems, such as not timely to grind the valve of diesel generator lease, restore its tightness, in a short period of time will develop the conical surface of valve seats, valve head, valve stem, root of ablation, lead to can’t repair need to replace new parts and the existing valve broken in danger of falling into the cylinders and the parts damaged.
Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
