        礦井裝載機和防爆礦井裝載機怎么進(jìn)行區分?

        內容詳情:
        礦井裝載機適合在金屬礦,巷道,隨道,窄體礦井作業(yè)。防爆礦井裝載機是煤礦專(zhuān)用防爆礦井裝載機,煤礦里有瓦斯可然度高,所以把礦井裝載機發(fā)動(dòng)機 車(chē)橋 電路,電瓶,燈,排氣空等發(fā)動(dòng)機有火花產(chǎn)生的地方都要做到防爆處理。
        The mine loader is suitable for working in metal mines, roadways, roadways and narrow mines. Explosion proof mine loader is a special explosion-proof mine loader for coal mines. There is a high probability of gas in the coal mine, so explosion-proof measures should be taken for the engine bridge circuit, battery, lamp, exhaust air and other places where sparks are generated by the engine of the mine loader.
        礦井裝載機和防爆礦井裝載機:巷道裝載機發(fā)出異響類(lèi)型及預防帶棚的透氣的礦山裝載機發(fā)動(dòng)機常見(jiàn)的異響主要有機械異響、燃燒異響、空氣動(dòng)力異響和電磁異響等
        Mine loaders and explosion-proof mine loaders: types of abnormal noise emitted by roadway loaders and prevention of common abnormal noise of ventilated mine loader engines with safety sheds mainly include mechanical abnormal noise, combustion abnormal noise, aerodynamic abnormal noise and electromagnetic abnormal noise
        (1)帶棚的透氣的礦山裝載機異響主要是運動(dòng)副配合間隙太大或配合面有損傷,運動(dòng)中引起沖擊和振動(dòng)造成的。帶棚的透氣的礦山裝載機因磨損、松動(dòng)或調整不當造成運動(dòng)副配合間隙太大時(shí),運轉中引起沖擊和振動(dòng),產(chǎn)生聲波,并通過(guò)機體和空氣傳給人耳,于是我們聽(tīng)到了響聲。帶棚的透氣的礦山裝載機如曲軸主軸承響、連桿軸承響凸輪軸軸承響、活塞敲缸響、活塞銷(xiāo)響、氣門(mén)腳響、正時(shí)齒輪響等,多是因配合間隙太大成的。
        (1) The abnormal noise of the ventilated mine loader with safety shed is mainly caused by the impact and vibration caused by the large fitting clearance of the movement pair or the damage of the fitting surface during the movement. When a breathable mine loader with a safety shed is worn, loosened or improperly adjusted, resulting in too large fitting clearance of the movement pair, impact and vibration are caused during operation, generating sound waves, which are transmitted to the human ear through the body and air, so we can hear the sound. Breathable 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)燃燒異響主要是發(fā)動(dòng)機不正常燃燒造成的。如汽油發(fā)動(dòng)機產(chǎn)生爆燃或表面點(diǎn)火時(shí),柴油發(fā)動(dòng)機工作粗暴時(shí),氣缸內均會(huì )產(chǎn)生極高的壓力波。這些壓力波相互撞擊并撞擊燃燒室壁和活塞頂,發(fā)出強烈的類(lèi)似敲擊金屬的聲響,是典型的燃燒異響。
        (2) Abnormal combustion noise is mainly caused by abnormal combustion of the engine. For example, when gasoline engine produces deflagration or surface ignition, and diesel engine works roughly, extremely high pressure waves will be generated in the cylinder. These pressure waves collide with each other and hit the combustion chamber wall and piston crown, making a strong sound similar to knocking metal, which is a typical combustion abnormal sound.
        (3)空氣動(dòng)力異響主要是在發(fā)動(dòng)機進(jìn)氣口、排氣口和運轉中的風(fēng)扇處,因氣流振動(dòng)而造成的。
        (3) Aerodynamic abnormal noise is mainly caused by airflow vibration at the engine air inlet, exhaust port and running fan.
        (4)電磁異響主要是發(fā)電機、電動(dòng)機和某些電磁器件內,由于磁場(chǎng)的交替變化,引起機械中某些部件或某一部分空間產(chǎn)生振動(dòng)而造成的。
        (4) The electromagnetic abnormal noise is mainly caused by the vibration of some parts or a part of the space in the machinery caused by the alternating change of magnetic field in the generator, motor and some electromagnetic devices.
