一、高压胶管的品种与规格目前工程机械上使用的高压胶管有钢丝编织和钢绳缠绕的两种,如图1、2所示。钢丝编织胶管由于受钢丝直径与强度的限制,承载能力随胶管直径的增大而降低,其耐脉冲性能较差;钢绳缠绕胶管承压能力较高,有良好的耐冲击及耐弯曲疲劳性能。 First, the type and specifications of high-pressure hoses High-pressure hoses used in the current construction machinery are steel wire braiding and steel wire winding two, as shown in Figure 1,2. Due to the limitation of the wire diameter and strength, the wire braided hose has a lower bearing capacity as the diameter of the hose increases, and its pulse resistance is poor. The steel wire winding hose has a higher pressure bearing capacity, and has good impact and bending fatigue resistance. .
