液压万能试验机历经在高压聚乙烯注塑桶的桶盖下边上面设备密封性连接头,应用离心水泵向桶内填满20±2℃的水,清除气体,超过值的要求压力后,恒压30分钟,然后加以检查。在应用全过程中将会会碰到汽车油箱总是振动的难题,是啥导致汽车油箱出現振动呢?网编这里告知大伙儿缘故:


Hydraulic universal testing machine passes through the sealing connector on the bottom of the barrel cover of the high-pressure polyethylene injection barrel, fills the barrel with water of 20 +2 C by centrifugal pump, clears the gas, after exceeding the required pressure, the pressure is constant for 30 minutes, and then checks it. In the whole process of application, we will encounter the problem that the automobile fuel tank always vibrates. What causes the vibration of the automobile fuel tank?


1.液压泵(齿轮油泵、齿轮泵、叶片泵、变量叶片泵、定量分析叶片泵、双联叶片泵、内齿轮油泵、外齿轮油泵)设备在了汽车油箱上。在进行大型的液压系统设计时,可以思考将液压泵和电机装置在油箱的外底座上面,并且运用软管与油箱进行连接。因为,很多人到液压系统设计时喜爱讲电动机和液压泵设备在汽车油箱的上边,假如是中小型的液压泵站还没有什么难题,可是如果是大型的液压泵站就不行了,将会致使油箱的振动。


1. Hydraulic pumps (gear oil pumps, gear pumps, vane pumps, variable vane pumps, quantitative analysis vane pumps, double vane pumps, internal gear oil pumps, external gear oil pumps) are equipped on the automobile fuel tank. When designing large-scale hydraulic system, we can think of putting the hydraulic pump and motor on the outer base of the tank, and connecting the tank with the hose. Because many people like to talk about the motor and hydraulic pump equipment on the top of the automobile tank when they design the hydraulic system. If it is a small and medium-sized hydraulic pump station, there is no problem, but if it is a large hydraulic pump station, it will not work, which will cause the vibration of the tank.


2.液压系统的结构欠佳,汽车油箱的不锈钢厚度过薄。液压系统设计时要过厚的厚钢板,一块儿在汽车油箱的档板、低板上再加筋板,一块儿更改回输油管末尾的样子或部位。


2. The structure of hydraulic system is not good, and the stainless steel thickness of automobile fuel tank is too thin. When designing the hydraulic system, we should add stiffened plates to the baffle and low plate of the automobile fuel tank, and change the shape or position of the end of the oil pipeline at the same time.


3.汽车油箱上边沒有设备防震动的方法。这一能够在汽车油箱的脚底和液压泵(齿轮油泵、齿轮泵、叶片泵、变量叶片泵、定量分析叶片泵、双联叶片泵、内齿轮油泵、外齿轮油泵)的基座下提升防止震动的方法。


3. There is no anti-vibration method on the top of the fuel tank. This method can be used to lift the foot sole of the automobile fuel tank and the base of the hydraulic pump (gear oil pump, gear pump, vane pump, variable vane pump, quantitative analysis vane pump, double vane pump, internal gear oil pump, external gear oil pump) to prevent vibration.


出現所述难题人们能够采用的挽救方法:扩大回输油管的直徑,也许转换大空间的调速阀,减少回液压油流的速率;以达减少油污流对汽车油箱的冲击性的用意。另外还可适当改变回油管出油口的方向,避免油流对油箱的直接冲击,也可以抵达减小液压万能试验机油箱振动的作用;但溢流阀的回油管出油口也不能彻底避开油箱侧壁;当油箱的振动和噪声不是主要矛盾时,汽车油箱外壁应接纳必然的油污流冲击性,以担负耗费油污流一些机械能的功效。防止了因髙速油污流对液压机拉伸试验机汽车油箱中液压油的立即冲击性而导致的强烈搅拌。


In order to reduce the impact of oil pollution flow on automobile fuel tank, the rescue methods that people can adopt are enlarging the diameter of oil return pipeline, perhaps changing the speed control valve in large space, and reducing the speed of hydraulic oil return flow. In addition, the direction of the oil outlet of the return pipe can be changed properly to avoid the direct impact of oil flow on the oil tank, and the effect of reducing the vibration of the oil tank of the hydraulic universal testing machine can also be achieved; however, the oil outlet of the return pipe of the relief valve can not completely avoid the side wall of the oil tank; when the vibration and noise of the oil tank are not the main contradiction, the external wall of the oil tank should accept the inevitable impact of the oil pollution flow to bear the cost. Efficiency of some mechanical energy in oil pollution flow. It prevents the strong stirring caused by the instantaneous impact of the speed oil pollution flow on the hydraulic oil in the automobile oil tank of the hydraulic press tension testing machine.
