选择适宜型号的空压机十分重要,型号过小无法满意日常用气需求,型号过小本钱过高还费电。今天,小编着重跟我们讨论一下选型济南空压机的技能根据,期望对我们有所协助。
It's very important to choose the right type of air compressor. If the model is too small, it can't meet the daily gas demand. If the model is too small, the cost is too high, and it also costs electricity. Today, Xiaobian focuses on discussing with us the skill basis of Jinan air compressor selection, hoping to help us.
一、排气量
1、 Exhaust volume
空压机排量的选择除满意凿岩机具需求外,还应考虑以下因素:
In addition to satisfying the needs of rock drilling machines, the following factors should also be considered in the selection of air compressor displacement:
向上排渣速度,空气介质条件下,速度不小于3000英尺(915米)/分;
The speed of upward slag discharge is not less than 3000 feet (915 m) / min in air medium;
排气量决定排渣速度,而不是排气压力;
The discharge rate is determined by the discharge volume, not the discharge pressure;
速度=排量/径流面积
Speed = discharge / runoff area
孔内径流面积=成孔截面积-钻杆截面积.
The runoff area in the hole = the cross-sectional area of the hole - the cross-sectional area of the drill pipe
排渣流量是高钻速,低消耗的必要条件,聪明的用户更倾向于选择大排量的空压机。
Slag discharge flow is a necessary condition for high ROP and low consumption. Smart users prefer to choose large displacement air compressor.
排气流量适宜性的判断:
Judgment of exhaust flow suitability:
排出的岩屑边沿较为锋利;
The edge of the discharged cuttings is sharp;
注意孔壁泄漏影响,孔浅和孔深的排量改变;
Pay attention to the influence of hole wall leakage and the change of displacement of shallow hole and deep hole;
松散地层,要注意操控排渣量,防止卡钻。
In loose formation, attention should be paid to control the amount of slag to prevent sticking.
二、排气压力
2、 Discharge pressure
济南空压机空气压力的凹凸,对潜孔冲击器的性能是决定条件,空气压力越高,潜孔冲击器的冲击能量越大,岩石就越容易被凿碎;
The higher the air pressure is, the greater the impact energy of DTH impactor is, and the easier the rock will be broken;
对于钻凿硬岩(f14以上),高能的冲击能力是穿孔作业的首要条件;
For drilling hard rock (above F14), high energy impact capability is the primary condition of drilling operation;
好的冲击器在高压条件下作业,穿孔速度是一条快速增长曲线。
When a good impactor works under high pressure, the perforation speed is a fast increasing curve.
