空压机的压力大小调节方式有两种：
There are two ways to adjust the pressure of the air compressor:
一、空压机压力调整
1、 Air compressor pressure adjustment
1、顺时针旋转压力调节螺钉，闭合和断开压力同步增大。
1. Turn the pressure adjusting screw clockwise to increase the closing and opening pressure synchronously.
2、逆时针旋液压钢坝转压力调整螺钉，闭合和断开压力同步减小。
2. Turn the pressure adjusting screw counterclockwise to reduce the closing and opening pressure synchronously.
二、压差调整
2、 Differential pressure adjustment
1、顺时针旋转压差调整螺丝，闭合压力不变，断开压力增大。
1. Turn the differential pressure adjusting screw clockwise, the closing pressure remains unchanged, and the opening pressure increases.
2、逆时针旋转压差调整螺钉，闭合压力不变，断开压力减小。
2. Rotate the differential pressure adjusting screw counterclockwise, the closing pressure remains unchanged, and the opening pressure decreases.
