Hydraulic universal testing machine is a large load, high availability of the universal testing machine, said the following note hydraulic components hydraulic universal testing machine installation, mainly in the following four aspects:
First, hydraulic universal testing machine, hydraulic components prior to installation, tocleaning with kerosene, two times the test pressure desirable work pressure, or the maximumpressure of one point five times. The test should be graded, not all of a sudden rise to test pressure, each level check once a.
Second, check the oil inlet and outlet seal ring is required before the installation, should highlight the installation plane sealing ring, to ensure the installation after a certain amount of compression, to prevent leakage.
Third, the directional control valve (control element to change gas or liquid flow is called thedirectional control valve) should ensure that the axis is arranged in a horizontal position.
Fourth, the fixing screw hydraulic system of hydraulic universal testing machine of thetightening force should be uniform, so that the components of the installation plane and the bottom plane good contact element.
液壓萬能試驗機是一種載荷大、實用性高的萬能試驗機,下面說下液壓萬能試驗機的液壓元件安裝注意事項,主要有以下四個方面:
,液壓萬能試驗機的液壓元件在安裝之前,要用煤油清洗,試驗壓力可取工作壓力的兩倍,或取使用壓力的一點五倍。試驗時要分級進行,不要一下子就升到試驗壓力,每升一級檢查一次。
第二,檢查進出油口處的密封圈是否合乎要求,安裝前密封圈應突出安裝平面,保證安裝后有一定的壓縮量,以防泄漏。
第三,方向控制閥(用以改變管道內氣體或液體流向的控制元件叫方向控制閥)應保證軸線呈水平位置安排。
第四,液壓萬能拉力試驗機液壓系統(tǒng)的各固定螺釘的擰緊力要均勻,使元件的安裝平面與元件底板平面很好的接觸。
