卡特彼勒液壓缸和閥脈沖試驗臺，是根據(jù)美國卡特彼勒的液壓缸和閥脈沖試驗臺的實際使用經(jīng)驗和技術(shù)要求，結(jié)合中國大陸的實際情況，而特別定制的脈沖試驗臺，在試驗臺的設(shè)計上做了一些改進(jìn)。
試驗臺是液壓、電氣一體的測試系統(tǒng)。它旨在完成液壓缸和閥的脈沖疲勞試驗和閥的泄漏試驗，測試液壓缸和閥在高壓脈沖之下的耐久性。為設(shè)備出廠，尤其是新研發(fā)的產(chǎn)品，提供了有力的試驗數(shù)據(jù)和性能保障。
脈沖疲勞試驗實際是一種破壞性的試驗，它測試設(shè)備在一定的高壓脈沖之下（42MPa及以下）的耐久性，是以最終實驗物件損毀為測試終止條件的。因此對于脈沖試驗臺本身的硬件和軟件的要求尤其為高。
DYNEX的主泵和換向閥以其長壽命，穩(wěn)定工作，高換向頻率，而特別適合于試驗臺的項目，在美國卡特彼勒的試驗臺，以及全球多種設(shè)備的試驗臺上已經(jīng)取得了廣泛的應(yīng)用。
上海曼理機(jī)電科技有限公司所提供的閥和液壓缸試驗臺已經(jīng)經(jīng)過了上千萬次的脈沖試驗，性能良好。
Cylinder and valve impulse test stand for Caterpillar R&D Center (China) Co., Ltd., are designed based on US Caterpillar's test stand experience and requirement, facing Chinese mainland real situation, the customized impulse test stands make some design progress on test stand then those in US.
Test stands integrate hydraulic and electrical control.It dedicated to accomplish cylinder and valve impulse fatigue test and valve leakage test,testing the cylinder and valve long life under high pressure impulse.It supplies believable test data and performance guarantee for components, especially for newly developed products, before them leave factory are very important.
Impulse fatigue test is a kind of test based on damage,which test a component's long-life(under 42Mpa or lower impulse pressure) till the product broken down.So a test stand itself's hardware and software must be strong enough and have good quality.
Dynex main pump and direction valve for their long-life and stable working performance, high frequency reversing are very suitable for test stand project,which have been used many years in US Caterpillar test stand and widely used in many kinds of other test stand in the world.
Marlin Engineered Technologies(Shanghai) supplies cylinder and valve test stand have worked through tens of millions times of impulse test and still work well.
