气体增压泵厂家分享钢管水压试验机的5种密封技术

发布时间:2019-11-11 15:46:43   发布人:http://www.sdjingtuo.com
  气体增压泵厂家研发生产各种材质的管材试验机(液压试验机),用于各种金属、非金属管材的水压、气密性、压力爆破等方面的试验,欢迎了解!
  The gas booster pump manufacturer develops and produces all kinds of material pipe testing machine (hydraulic testing machine), which is used for the test of water pressure, air tightness, pressure blasting and other aspects of various metal and non-metal pipes. Welcome to know!
  承受压力的钢管,如锅炉管、油管、套管等,要进行水压试验,水压试验机是生产压力管的必备设备。液压试验机通过向管道内注水、加压、保压来测试管壁承受压力的能力。从目前使用的液压试验机来看,高压液压试验机的核心技术问题是试验头密封技术。
气体增压泵
  Steel pipes under pressure, such as boiler pipes, oil pipes, casings, etc., shall be subject to hydrostatic test, and the hydrostatic testing machine is the necessary equipment for the production of pressure pipes. The hydraulic testing machine tests the ability of the pipe wall to bear pressure by injecting water, pressurizing and maintaining pressure into the pipe. From the perspective of the current hydraulic testing machine, the core technology of the high-pressure hydraulic testing machine is the sealing technology of the test head.
  目前,国内外使用的液压试验机可分为径向密封和端面密封。端面密封只适用于低水压试验。无缝钢管水压试验(高压)采用径向密封。
  At present, the hydraulic testing machines used at home and abroad can be divided into radial seal and face seal. Face seal is only suitable for low water pressure test. The radial seal is adopted in the hydrostatic test (high pressure) of seamless steel pipe.
  (a)普通外径密封:通过水压使密封圈膨胀,密封钢管外径;(b)径向密封室加压外径密封:密封圈依靠外部水压密封钢管外径;(c)径向密封室加压内径密封:密封圈依靠外部水压密封钢管内径;(d)普通内径密封:通过水压使密封圈膨胀,密封钢管内径;(e)端面密封:通过外力压缩密封圈,实现端面密封。
  (a) ordinary outer diameter seal: expand the seal ring by water pressure, and seal the outer diameter of steel pipe; (b) pressurize the outer diameter seal of radial seal chamber: seal the outer diameter of steel pipe by external water pressure; (c) pressurize the inner diameter seal of radial seal chamber: Seal the inner diameter of steel pipe by external water pressure; (d) ordinary inner diameter seal: expand the seal ring by water pressure, and seal the inner diameter of steel pipe; (E) end face seal: compress by external force Seal ring to achieve end face seal.
