高压软管由高压钢丝编织胶管和管结头组成。结头按固定方式分为可拆卸与不可拆卸,目前国内液压系统中所使用的均为不可拆卸式,即接头芯的配合为模压锁紧。 高压软管常见的损坏主要有爆裂和接头螺母滑扣或球头密封面损坏等。 一、高压软管爆裂的原因 1.农具或收割台等提升到运输位置后在不平的路面上高速行驶,悬挂体剧烈颠簸使高压软管中产生比原来大几倍的冲击载荷,此时安全阀在瞬间又难起作用迫使软管爆裂。 2.错误使用“中立”位置。作业中因地面不平农具起伏,在“中立”位置时迫使油缸活塞运动产生的高压超过软管承压能力而破裂n
High-pressure hose made of high-pressure steel wire braided hose and pipe knot. Knot according to the fixed way can be divided into detachable and non-removable, the current domestic hydraulic system are used are not removable, that is, the connector core with molded locking. Common high-pressure hose damage are the main burst and the joint nut slide or ball head sealing surface damage. First, the causes of high-pressure hose burst 1. Farm tools or headers and other raised to the transport position on the uneven road at high speed, heavy buoyancy hoses make high-pressure hose in the original several times larger than the impact load, this time safe Valve in an instant hard to force the hose burst. 2. Wrong use of “neutral” position. Work due to ground uneven farm tools ups and downs in the “neutral” position forcing cylinder piston pressure generated by high pressure than the hose pressure and rupture n
