Full preparation before equipment operation is an important link to ensure good performance, safety and reliability of mechanical equipment after delivery. The overall inspection includes no-load test run, load test run, inspection after test run, etc. Pressure test and compactness test are also needed for important equipment. For mining loaders and other machinery with complex working environment, the preparation work is particularly important to ensure that the machinery can play a higher role in the follow-up construction and ensure the smooth operation process.

礦用裝載機作業(yè)前準備工作的主要內(nèi)容包括：

The main contents of preparation before operation of mine loader include:

1、應該檢查電源系統(tǒng)：電纜、接頭應改確保完好，無破損的現(xiàn)象；連接線路應完好，無燒損、松脫現(xiàn)象。

1. First of all, the power supply system should be checked: the cables and joints should be changed to ensure that they are in good condition without damage; The connecting line shall be in good condition without burning and loosening.

2、檢查裝載機的液壓系統(tǒng)：液壓系統(tǒng)的元件及其聯(lián)接管路之間連接應緊固，無明顯滲漏現(xiàn)象；液壓油位應符合規(guī)定（油量約占油箱總?cè)莘e的4/5之間）。

2. Check the hydraulic system of the loader: the connection between the components of the hydraulic system and its connecting pipes should be tight without obvious leakage; The hydraulic oil level should meet the requirements (the oil volume accounts for about 4 / 5 of the total volume of the oil tank).

3、檢查礦用裝載機的操縱系統(tǒng)：各操縱手柄應處于中立位置，操縱應靈活，無卡滯現(xiàn)象。

3. Check the operating system of mine loader: all operating handles should be in the neutral position, and the operation should be flexible without jamming.

4、檢查輸送系統(tǒng)：輸送帶應完好，張緊度合適；滾輪、滾筒轉(zhuǎn)動靈活，無異常音響。

4. Check the conveyor system: the conveyor belt should be in good condition with proper tension; The roller and roller can rotate flexibly without abnormal sound.

5、發(fā)動機運轉(zhuǎn)時，每個氣缸每分鐘吸入空氣2～4m3。為了保證進入氣缸的空氣干凈，使用前須對空氣濾清器加強檢查，定期清洗。

5. When the engine is running, each cylinder inhales 2 ~ 4m3 air per minute. In order to ensure that the air entering the cylinder is clean, the air filter must be inspected and cleaned regularly before use.

6、安裝空氣凈化濾清裝置：礦山井下開采空間狹小、通風條件差,礦井鏟車作業(yè)時產(chǎn)生的尾氣難以及時、順暢排放到礦井之外,由此造成井下空間污染嚴重,給工作人員的健康帶來危害。礦井鏟車本文主要講述礦井鏟車柴油機尾氣的危害,提出凈化方法,并介紹水洗式尾氣過濾裝置。

6. Installation of air purification and filtration device: the mining space is narrow and the ventilation condition is poor, so the tail gas produced by forklift operation is difficult to be discharged out of the mine timely and smoothly, which causes serious pollution of underground space and brings harm to the health of workers. Mine forklift this paper mainly describes the harm of mine forklift diesel engine exhaust, puts forward the purification method, and introduces the water washing exhaust gas filtering device.
