Connected between each joint of each circuit by conduit, as shown in Figure 6.Connected between each circuit by pole, such as
Shown in Fig. 7.Use bolt between circuit and end cap to fix, as shown in Figure 8.
The course of work：
One) folding process
When carrying out blade folding, fold and lead to hydraulic oil in voltage supply pipeline 8, now deploy the connection low pressure of voltage supply pipeline 9 and return
Oil, reciprocable valve connection folds voltage supply pipeline 8 with damper 6 to damper voltage supply, while folding voltage supply pipeline by folding voltage supply
Pipeline 8, the folding pipeline for folding the connection blade folding device of pipeline 7 of blade folding device carry out blade folding to its voltage supply,
Now expansion circuit deploys pipeline by 5,9 connection blade folding devices and expansion voltage supply pipeline is used as returning in folding process
Oil return line.
Two) process is deployed
When carrying out blade expansion, fold voltage supply pipeline and connect low pressure oil return, expansion voltage supply pipeline leads to hydraulic oil, reciprocable valve connection
Deploy voltage supply pipeline 9 with damper 6 to damper voltage supply, while 5 ends, 9 ends connection expansion voltage supply pipeline by deploying circuit
Its voltage supply is given with the expansion pipeline of blade folding device, blade expansion is carried out, circuit is now folded and connects blade by 7 ends, 8 ends
Folding devices fold pipeline and folding voltage supply pipeline are used as the oil return circuit during expansion.
