为什么空压机够大仍可能供气不足 Why a large compressor may still provide insufficient air
空压机铭牌输出不等于凿岩机末端实际可用气量。长距离、小管径、多接头、泄漏和多台同时工作都会造成压力与流量损失。 Nameplate output is not the usable supply at the drill. Long runs, small diameters, multiple fittings, leaks and simultaneous operation cause pressure and flow losses.
需要收集哪些现场数据 Site data to collect
应同时记录空压机额定排气量与压力、主管支管长度和管径、接头数量、末端压力及其他用气设备。 Record compressor rated flow/pressure, main and branch hose lengths/diameters, fitting count, pressure at the tool and other air users.
不凭型号直接给固定管径 Do not choose a fixed hose size from the model alone
缺少完整现场条件时，本站不直接给出一个适用于所有项目的固定管径，避免误导。 Without complete site conditions, this site does not specify one hose diameter for every project.
