選擇適宜型號的空壓機(jī)十分重要，型號過小無法滿意日常用氣需求，型號過小本錢過高還費(fèi)電。今天，小編著重跟我們討論一下選型濟(jì)南空壓機(jī)的技能根據(jù)，期望對我們有所協(xié)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、排氣量
1、 Exhaust volume
空壓機(jī)排量的選擇除滿意鑿巖機(jī)具需求外，還應(yīng)考慮以下因素：
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,空氣介質(zhì)條件下,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;
排氣量決定排渣速度,而不是排氣壓力;
The discharge rate is determined by the discharge volume, not the discharge pressure;
速度=排量/徑流面積
Speed = discharge / runoff area
孔內(nèi)徑流面積=成孔截面積-鉆桿截面積.
The runoff area in the hole = the cross-sectional area of the hole - the cross-sectional area of the drill pipe
排渣流量是高鉆速,低消耗的必要條件,聰明的用戶更傾向于選擇大排量的空壓機(jī)。
Slag discharge flow is a necessary condition for high ROP and low consumption. Smart users prefer to choose large displacement air compressor.
排氣流量適宜性的判斷:
Judgment of exhaust flow suitability:
排出的巖屑邊沿較為鋒利；
The edge of the discharged cuttings is sharp;
注意孔壁泄漏影響,孔淺和孔深的排量改變;
Pay attention to the influence of hole wall leakage and the change of displacement of shallow hole and deep hole;
松散地層,要注意操控排渣量,防止卡鉆。
In loose formation, attention should be paid to control the amount of slag to prevent sticking.
二、排氣壓力
2、 Discharge pressure
濟(jì)南空壓機(jī)空氣壓力的凹凸，對潛孔沖擊器的性能是決定條件，空氣壓力越高，潛孔沖擊器的沖擊能量越大，巖石就越容易被鑿碎；
The higher the air pressure is, the greater the impact energy of DTH impactor is, and the easier the rock will be broken;
對于鉆鑿硬巖(f14以上)，高能的沖擊能力是穿孔作業(yè)的首要條件；
For drilling hard rock (above F14), high energy impact capability is the primary condition of drilling operation;
好的沖擊器在高壓條件下作業(yè)，穿孔速度是一條快速增長曲線。
When a good impactor works under high pressure, the perforation speed is a fast increasing curve.
