液压泵和液压马达的型式试验一机部标准是根据一般液压设备对这两类液压元件的共同性基本使用要求提出的。这两项标准的实施,对产品质量的提高起着一定的积极作用。本文拟对一机部标准JB2147-77和JB2148-77的内容加以说明。型式试验是保证产品结构完整、性能可靠和使用耐久的重要手段。下面逐项简略解释试验项目。1.跑合试验目的是使新制造的液压泵 Hydraulic pump and hydraulic motor type test - Machine standard is based on the general hydraulic equipment on the common use of these two types of hydraulic components of the proposed requirements. The implementation of these two standards plays an active role in improving product quality. This article intends to a machine department standard JB2147-77 and JB2148-77 content to be described. Type testing is to ensure that the product structure integrity, reliable performance and durability of an important means. The following one by one briefly explain the pilot project. 1. Run-in test The purpose is to make a newly manufactured hydraulic pump
