bleed-off

基本解释

Second, there is a leak in the system that is allowing pressure to bleed off when the unloader is put in bypass.
第二，系统泄露，以至于在减压器安置在旁路时压力被释放。
When no bubbles come out from the flowline, open the relief valve a little to bleed off slowly. When the pressure gauge reads 0, open the valve completely.
当出油管没有气泡冒出时，将卸压阀门打开一点，使压力慢慢卸掉，当压力表显示值为0时，阀门全部打开。
