The oil temperature is too high. Engineering machinery operation, the hydraulic system power loss due to fluid leaving the heat , coupled with the impact of the outside temperature ( especially in the summer ) , make the oil dramatically. Fluid temperature is higher, the more easy to aging rubber elasticity variation, strength and sealing performance, high pressure hose will soon burst. Thus, in operation, when Hydraulic pipe fittings system in the temperature is too high , too fast , it is timely to identify the reasons , be excluded ; summer jobs , especially in continuous operation , should take the necessary measures to cool .
hydraulic tube fittings,hydraulic hose,hydraulic fittings is with a one-way valve, one is without a check valve. Application with check valve, check valve and the gas source is connected to the end, when you disconnect the check valve closes automatically when you turn on the activity side thimble-way valve is opened. Is the use of self-locking ball is embedded in the groove, while the locking balls from "tapered cylindrical ---" sleeves.
