A、Introduction
JSQ-Ⅲ Hydrostatic Release Unit is a device used for releasing inr surface and makes the liferaft the ship sinks to a certain depth, the weak rope will be snapped,thus the liferaft separated from the ship.(See )
D、Releasing Process
In case of rapid sinking of the ship,there is no time for manual releasing, So when the sinking ship submerges at a certain depth, the liferaft can be released automatically by HRU The process is as follows:(See —D)
1、The liferaft sinks together with the ship.(See )
2、When ship sinks with in a depth of less than 4m,HRU immediately looses the securing band on the liferaft, then the liferaft begins to rise.(See )
3、With the continual sinking of the ship and rising of the line is gradually drawed out and in turn the infiation system is operated,then the liferaft will be completed its infaltion.(See )
4、Under action of buoyance produced by the infalted liferaft,the weak rope connecting with HRU is snapped,the liferaft then is separated from the ship,and the people falling in the sea can embark on the liferaft.( See )
E、Maintenance
1、Ordinarily HRU can’t be released manually at random or pushed the short shaft by any cone.
2、In order to ensure the inlet not to be clogged, HRU should not be painted.
3、Inspect the wear
