耐壓性和耐久性是評(píng)析液壓油缸優(yōu)劣的兩個(gè)重要標(biāo)準(zhǔn)，液壓油缸能不能長時(shí)間高負(fù)荷正常運(yùn)轉(zhuǎn)耐久性和耐壓性自然是兩個(gè)重要參數(shù)，所以對(duì)于液壓油缸的參數(shù)我們要非常了解才能去甄別真正的優(yōu)質(zhì)設(shè)備和偽劣設(shè)備。
不過如何去獲得這兩個(gè)重要參數(shù)？
自然是通過相關(guān)的設(shè)備去檢測。其中，耐久性指的就是油缸在額定的工作效率和工作條件下長時(shí)間運(yùn)行的能力，因此液壓油缸的耐久性是需要高負(fù)荷、長時(shí)間才能檢測出來。有句名言說：時(shí)間是檢驗(yàn)真理的唯一標(biāo)準(zhǔn)，用在這里實(shí)在是恰當(dāng)不過。
在額定壓力下，被測試的油缸以設(shè)計(jì)要求的最高速度連續(xù)運(yùn)行，一般時(shí)間控制在8小時(shí)，這樣連續(xù)不間斷的工作并且要求液壓油缸的速度誤差在10%以內(nèi)，如果在這種測試下能夠完成，那么這就說明耐久性符合要求。
對(duì)于耐壓性的測試，則是需要是液壓油缸在短時(shí)間內(nèi)施加它額定范圍內(nèi)的最高壓力值，經(jīng)過反復(fù)測試之后若試驗(yàn)設(shè)備仍然能夠正常運(yùn)行，就說明這件產(chǎn)品是合格的。
通俗點(diǎn)講，測試一種設(shè)備的最好方式就是讓其在極限狀態(tài)下運(yùn)行從而得到最真實(shí)有效地?cái)?shù)據(jù)，液壓油缸自然也是如此。
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.
