矿井装载机和防爆矿井装载机的区别

内容详情:
矿井装载机适合在金属矿,巷道,随道,窄体矿井作业。防爆矿井装载机是煤矿专用防爆矿井装载机,煤矿里有瓦斯可然度高,所以把矿井装载机发动机车桥电路,电瓶,灯,排气空等发动机有火花产生的地方都要做到防爆处理。
Mine loader is suitable for metal mine, roadway, with the road, narrow body mine operation. The explosion-proof mine loader is a special explosion-proof mine loader for coal mine. The gas in the coal mine is high, so the engine bridge circuit, battery, lamp, exhaust air and other places where the engine sparks should be explosion-proof.
矿井装载机和防爆矿井装载机:巷道装载机发出异响类型及预防带安 全棚的透气的矿山装载机发动机常见的异响主要有机械异响、燃烧异响、空气动力异响和电磁异响等
Mine loaders and explosion-proof mine loaders: types of abnormal noise emitted by roadway loaders and prevention of abnormal noise emitted by mine loaders with ventilation and safety shed. The common abnormal noise of engine mainly includes mechanical abnormal noise, combustion abnormal noise, aerodynamic abnormal noise and electromagnetic abnormal noise
(1)带安 全棚的透气的矿山装载机异响主要是运动副配合间隙太大或配合面有损伤,运动中引起冲击和振动造成的。带安 全棚的透气的矿山装载机因磨损、松动或调整不当造成运动副配合间隙太大时,运转中引起冲击和振动,产生声波,并通过机体和空气传给人耳,于是我们听到了响声。
(1) The abnormal noise of mine loader with safety shed is mainly caused by the impact and vibration caused by too large fit clearance or damage of fit surface. When the gap between moving pairs of mine loader with safety shed is too large due to wear, looseness or improper adjustment, it will cause impact and vibration during operation, and produce sound wave, which will be transmitted to human ears through the body and air, so we can hear the sound.
带安 全棚的透气的矿山装载机如曲轴主轴承响、连杆轴承响凸轮轴轴承响、活塞敲缸响、活塞销响、气门脚响、正时齿轮响等,多是因配合间隙太大成的。
Mine loaders with safety sheds, such as crankshaft main bearing, connecting rod bearing, camshaft bearing, piston knocking, piston pin, valve foot and timing gear, are mostly caused by too large fit clearance.
(2)燃烧异响主要是发动机不正常燃烧造成的。如汽油发动机产生爆燃或表面点火时,柴油发动机工作粗暴时,气缸内均会产生高的压力波。这些压力波相互撞击并撞击燃烧室壁和活塞顶,发出强烈的类似敲击金属的声响,是典型的燃烧异响。
(2) Abnormal combustion noise is mainly caused by abnormal combustion of engine. If the gasoline engine deflagration or surface ignition, diesel engine rough work, the cylinder will produce high pressure wave. These pressure waves collide with each other and strike the combustion chamber wall and piston crown, making a strong sound similar to knocking metal, which is a typical abnormal combustion sound.
(3)空气动力异响主要是在发动机进气口、排气口和运转中的风扇处,因气流振动而造成的。
(3) The aerodynamic abnormal noise is mainly caused by the airflow vibration at the intake, exhaust and running fan of the engine.
(4)电磁异响主要是发电机、电动机和某些电磁器件内,由于磁场的交替变化,引起机械中某些部件或某一部分空间产生振动而造成的。
(4) The abnormal electromagnetic noise is mainly caused by the vibration of some parts or parts of the machinery due to the alternating change of the magnetic field in the generator, motor and some electromagnetic devices.
