功能簡介：    Functions:

l 該機符合國家標準GT/T2611-2007《試驗機通用技術條件》、JJG139-1999 《拉力、壓力和萬能試驗機國家計量檢定規程》、GB/T23858-2009《檢查井蓋》、CJ/T3012-1993 《鑄鐵檢查井蓋》、JC889-2001《鋼纖維混凝土檢查井蓋》；主要用于鑄鐵井蓋、復合材料井蓋、鋼釬混凝土井蓋等各種規格、材質的井蓋進行抗壓試驗檢測，并檢測井蓋在抗壓過程中變形量。增加附具，可完成其它材料的抗壓試驗檢測

l The machine accords with GT/T2611-2007 General Requirements for Testing Machines, JJG139-1999 Verification Regulation of Universal Tension and Compression Testing Machine, GB/T23858-2009 Manhole Cover, CJ/T3012-1993 Cast Iron Manhole Top, JC889-2001 Steel Fiber Reinforced Concrete Checking Well cover and is mainly used to do the compression test of cast iron manhole cover, compositive manhole cover, steel fiber reinforced concrete well cover. If equipped with other accessories, it can do the compression test to other materials.

l 該采用兩立柱結構框架結構，油缸上置，高精度電液伺服閥及精密伺服液壓缸，可對試驗力、位移變形進行多種模式的閉環控制。可以實現連續加載和任意負荷下保持載荷功能。試驗過程中無沖擊和震動，具有良好的讀數穩定性。

  The machine adopts two columns structure, upper hydra-cylinder, high precision electro-hydraulic servo valve and precision servo hydra-cylinder. There are several closed loop control mode to test force, displacement and deformation. The continuous loading and load keeping can be realized by the machine without impacting and shaking in the test.
