软管总成,软管分需剥外胶与不需剥外胶两种类型。接头也不一样,需剥外胶类型的接头套的沟槽不要太锋利,否则会损伤软管的增强层。正确扣压接头,对软管总成的安全和正常工作是至关重要的。可以采用实壁或结构壁多种设计,其连接主要采用溶剂粘接方式。

主要是因为PVC原材料的生产对原油的依赖性不如其他热塑性塑料大,使其生产成本相对较为低廉。软管总成内径要适当,管径过小会加大管路内介质的流速,使系统发热,降低效率,而且会产生过大的压力,影响整个系统的性能。安装时,应使用正式的管架固定,与高压管子、管件接触的管架上,按设计要求安装保护套管。安装时应露出管端螺纹的倒角。

软管总成,安装密封垫时,不要用金属丝吊放,事先应在管口及垫上涂以黄油,软金属高压垫片应准确地放入密封座内。随着中国海洋石油开发战略的实施,海洋石油开采对油管性能的要求将不断提高。如不能正确地使用和保养,也会严重影响其使用质量和寿命,甚至发生不应有的严重事故,对财物造成损失。软管主要用作电线、电缆、自动化仪表信号的电线电缆保护管和民用淋浴软管,耐腐蚀能力很强,温度适应范围广,软管的安装连接,无论在自然状态下,还是在运动状态中,其弯曲半径均不能小于软管制造厂规定的小弯曲半径。

软管总成,现有的高压软管的性能和寿命,相对来说不存在技术难题。只是高压软管总成的性能和寿命,受限于高压软管接头组装的制造水平—软管总是在接头部位提前损坏。软管总成的质量直接体现液压机械的质量,液压机械的制造者对现有产品,一直不甚满意。

Hose assembly, hoses need to be stripped and do not need to be stripped two types of rubber. Joints are not the same, need to strip out the type of joint sleeve groove is not too sharp, otherwise it will damage the hose reinforcement layer. It is vital to the safety and normal operation of the hose assembly that the joint is correctly pressed. It can be designed with solid wall or structural wall, and its connection is mainly by solvent bonding.

The main reason is that the production of PVC raw material is less dependent on crude oil than other thermoplastics, making its production cost relatively low. Hose assembly inner diameter should be appropriate, small pipe diameter will increase the flow rate of medium in the pipeline, make the system heating, reduce efficiency, and will produce too much pressure, affect the performance of the whole system. During installation, a formal pipe rack shall be used to fix it. The pipe rack in contact with high-pressure pipes and pipe fittings shall be installed with protective casing according to design requirements. The chamfering of pipe end thread should be exposed during installation.

Hose assembly, installation of gasket, do not use wire hanging, should be in advance on the nozzle and gasket with butter, soft metal high pressure gasket should be accurately placed in the sealing seat. With the implementation of China's offshore oil development strategy, the requirements of offshore oil exploitation on pipeline performance will be continuously increased. If not properly used and maintained, it will seriously affect the quality and life of its use, and even cause the loss of property due to the occurrence of serious accidents. Hose is mainly used for wire, cable, automation instrument signal cable protection tube and civilian shower hose, corrosion resistant ability is very strong, suitable temperature range is wide, the installation of the hose connection, no matter in natural state, or in a state of movement, the bending radius is not less than small bending radius of the hose factory regulations.

The main reason is that the production of PVC raw material is less dependent on crude oil than other thermoplastics, making its production cost relatively low。 Hose assembly inner diameter should be appropriate, small pipe diameter will increase the flow rate of medium in the pipeline, make the system heating, reduce efficiency, and will produce too much pressure, affect the performance of the whole system。 Close pressure relief valve, start software, adjust pressure of hydraulic station, pressure holding time, pressure boost time, high pressure time, pressure relief time, and test times。 Hose assembly as a component of hydraulic system, its performance and life are relatively weak, become the barrier of high pressure selection。

Hose assemblies, the performance and life of existing high pressure hoses, are relatively free of technical challenges. Only the performance and life of the high pressure hose assembly is limited by the manufacturing level of the high pressure hose connection assembly - the hose is always damaged in advance at the connection site. Hose assembly quality directly reflects the quality of hydraulic machinery, hydraulic machinery manufacturers to existing products, has not been very satisfied.
