我厂生产内燃机配件数百种,其中有很多配件需要打压,如汽缸套、溢流阀、安全阀、机油系流分油接头体等。为了保证产品试压质量,我们设计并制造一台水压试验台。 本试压台重点解决汽缸套打压问题。产品汽缸套材质为特种铸铁铬钼铜(HJT—2A)含十种定量金属。缸套规格;φ180×395mm,壁厚9.5mm。该缸套是在高温高压冲击载荷下工作,在机械加工后技术验收条件规定:距缸套顶面140mm、内径进行120kg/cm~2打压、及整体5kg/cm~2打压,
I plant hundreds of internal combustion engine parts, of which there are many parts need to suppress, such as cylinder liners, relief valves, safety valves, oil system oil flow distributor body. In order to ensure the quality of product pressure test, we design and manufacture a hydraulic test stand. The test pressure to focus on solving pressure cylinder liner problems. Product cylinder liner material for the special cast iron chrome molybdenum copper (HJT-2A) with ten kinds of quantitative metal. Cylinder liner specifications; φ180 × 395mm, wall thickness 9.5mm. The cylinder liner is working under high temperature and high pressure impact load, and the technical acceptance condition after machining defines that: the pressure is 120kg / cm ~ 2 from the top surface of the cylinder liner and the inner diameter is suppressed by the pressure of 5kg / cm ~ 2,
