要检查和调整压力调节阀,请执行以下步骤:
- 释放压力调节阀的气压。
- 从起动马达的控制阀断开压力调节阀。
- 将 8T-0849 压力表总成 连接到调节器出气口 (3) 。
- 将气压施加到调节器进口 (2) 并测量压力。
- 将压力调节阀调整到建议气压设置中所示的数值。
- 释放压力调节阀的气压。
- 拆除 8T-0849 压力表总成 。 将气压调节器连接到空气起动马达的管路。
必须检查每个发动机应用场合,以确定最有利的起动条件。 压力调节阀的设定受以下因素的影响:
- 来自起动期间发动机拖动的附加装置的负荷
- 环境温度条件
- 机油粘度
- 储气罐的容量
- 发动机状况
最小和最大工作压力取决于起动机的类型。 建议的工作压力标注在起动机的识别标签上。
采用较高压力设定值可以提高起动马达的扭矩和加速发动机的转动。 采用较低压力设定值可以有效延长特定储气罐容量下的发动机转动时间。 此外,较低的气压可减小对起动马达的磨损。
