耐压性和耐久性是评析液压油缸优劣的两个重要标准,液压油缸能不能长时间高负荷正常运转耐久性和耐压性自然是两个重要参数,所以对于液压油缸的参数我们要非常了解才能去甄别真正的优质设备和伪劣设备。
不过如何去获得这两个重要参数?
自然是通过相关的设备去检测。其中,耐久性指的就是油缸在额定的工作效率和工作条件下长时间运行的能力,因此液压油缸的耐久性是需要高负荷、长时间才能检测出来。有句名言说:时间是检验真理的唯一标准,用在这里实在是恰当不过。
在额定压力下,被测试的油缸以设计要求的最高速度连续运行,一般时间控制在8小时,这样连续不间断的工作并且要求液压油缸的速度误差在10%以内,如果在这种测试下能够完成,那么这就说明耐久性符合要求。
对于耐压性的测试,则是需要是液压油缸在短时间内施加它额定范围内的最高压力值,经过反复测试之后若试验设备仍然能够正常运行,就说明这件产品是合格的。
通俗点讲,测试一种设备的最好方式就是让其在极限状态下运行从而得到最真实有效地数据,液压油缸自然也是如此。
Pressure and durability Comment two important criteria of the merits of hydraulic cylinders, hydraulic cylinders can long high load durability and withstand voltage of the normal operation of natural two important parameters, the parameters of the hydraulic cylinder to be very understood that in order to go to the screening real quality equipment and shoddy equipment.
But how to get these two important parameters?
Is naturally associated equipment to detect. Where durability refers to the capacity of the fuel tank in the rated efficiency and working conditions, long-running, the durability of the hydraulic cylinder is high load for a long time can be detected. Is a famous saying: the time is the sole criterion for testing truth, and is used here is appropriate.
At rated pressure, the cylinder being tested to the maximum speed of the design requirements for continuous operation time, generally controlled within 8 hours, such uninterrupted work and requires a hydraulic cylinder, the speed error is within 10%, and if in this testing can completed, then this is the durability to meet the requirements.
Pressure resistance test needs to be applied to the hydraulic cylinder in a short period of time it rated within the highest pressure value, the test equipment is still able to operate normally after repeated tests, this product is qualified.
Popular speak, the best way to test a device is allowed to run in the limit state data to get the most realistic and effective hydraulic cylinder naturally.
