耐高温动力转向压力胶管

[中文适用范围]： 该 SAE 标准涵盖两种类型的软管，由织物增强材料和合成橡胶制成，与端部配件组装在一起，用于高温汽车动力转向应用，作为 -40 至 +150 °C（-40 至 +最大工作压力 302 °F)，最大工作压力 10.3 MPa (1500 psi)。这些软管适用于需要降低泵压力脉动幅度的应用。 A 级软管的标称外径为 19.84 毫米（0.781 英寸）。 B 级软管是一种轻质软管，标称外径为 17.91 毫米（0.705 英寸）。该规范定义了液压转向系统中将动力转向液从转向泵输送到转向器的柔性连接器的最低性能水平。 [外文原描述]： This SAE Standard covers two types of hose fabricated from textile reinforcement and synthetic rubber, assembled with end fittings for use in high-temperature automotive power steering applications as flexible connections within the temperature range of −40 to +150 °C (−40 to +302 °F) maximum and 10.3 MPa (1500 psi) maximum working pressure. These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsation is required. Class A hose has a nominal OD of 19.84 mm (0.781 in). Class B hose is a lightweight hose with a nominal OD of 17.91 mm (0.705 in). This specification defines the minimum performance levels of a flexible connector in the hydraulic steering system to convey power steering fluid from the steering pump to the steering gear.Cross Reference: ASTMD380,ASTMD413
