产品描述
彼得罗夫是俄罗斯Hydrosila Group的老采购了，同AAK有一些非标的先导式液压溢流阀在合作，也经常讨论一些先导式液压溢流阀的疑难杂症。去年下半年，他们需要采购先导式液压溢流阀来试机一款农机设备。时间关系，彼得罗夫从俄罗斯液压溢流阀厂家采购，该工厂在30天就交付了30个先导式液压溢流阀样品。试机时，先导式液压溢流阀开启前的1.5MPa左右就有啸叫，启动和停止也均有啸叫。彼得罗夫联系了原液压溢流阀厂家，工厂反馈该非标定制完全依据所提供的图纸的，尺寸精度也都符合要求的。他们工程师单独检测液压溢流阀，确实无异常。老板不满意试机被耽误一个礼拜了，责令彼得罗夫重新采购先导式液压溢流阀。 因为之前碰到的液压溢流阀难题，都是AAK解决的，彼得罗夫又邮件给我了。AAK工程师根据他的故障描述，先导式溢流阀图纸，农机液压系统工作参数，以及试机的视频，初步判断先导式液压溢流阀的设计可能有问题。得知他还有一个月的弹性，AAK可以在30天内，修改先导式液压溢流阀原设计，并寄出12个试样。4礼拜后，AAK寄出20个先导式液压溢流阀样品，安装调试无啸叫，并多次启动或关闭液压动力单元，依然无啸叫。 彼得罗夫很惊讶AAK工程师一次就找到了液压溢流阀问题点并解决了，而俄罗斯原液压溢流阀厂家，却束手无策？ 因为先导式溢流阀的啸叫往往是高压油通过阻尼孔或阀口产生的，AAK工程师在原设计上新增阀座斜孔，消振腔。这样就能提高先导式液压溢流阀的动态特性和静态特性，消除啸叫降低噪声，同时提高了压力控制精度。AAK强大的工程师团队，不仅有德国HAWE的理念，也有意大利Oil Control的经验，找问题，一找一个准。 试机成功后，彼得罗夫私下告知，老板很满意他此次找到了强的液压溢流阀厂家，不仅仅解决了俄罗斯原厂不能解决的问题，并价格也要便宜30%，以后的液压溢流阀试单，AAK是他的首选。 AAK液压溢流阀，超强技术团队，你也可以小试一单！

Petrov is an old purchaser of Hydrosila Group in Russia. He cooperates with AAK on some non-standard hydraulic pilot operated relief valves and often discusses some difficulties and complications of hydraulic pilot operated relief valves. In the second half of last year, they needed to purchase a hydraulic pilot operated relief valve to test an agricultural machinery equipment. Due to urgent time, Petrov purchased from a Russian hydraulic relief valve manufacturer, who delivered 30 hydraulic pilot operated relief valves in 30 days. During the test run, the hydraulic pilot operated relief valves screamed at about 1.5MPa before opening, as well as at the start and stop. Petrov contacted the manufacturer of the hydraulic relief valves, and the manufacturer replied that the non-standard customization was completely based on the drawings provided, and the dimensional accuracy also met the requirements. Their engineers independently tested the hydraulic relief valves and found that there was really no abnormality. The boss was dissatisfied with the one week of delay due to the test run and asked Petrov to repurchase the hydraulic pilot operated relief valves. Because the hydraulic relief valve problems encountered before were solved by AAK, Petrov emailed me again. AAK engineer preliminarily judged that there may be problems in the design of the hydraulic pilot operated relief valve according to his fault description, the drawings of the pilot operated relief valve, the working parameters of the hydraulic system of agricultural machinery, and the video of the test machine. Knowing that he still has one month of flexibility, AAK can modify the original design of the hydraulic pilot operated relief valve and send 12 samples within 30 days. Four weeks later, AAK sent 20 samples of hydraulic pilot operated relief valves, which were installed and debugged without screaming, and the hydraulic power unit was started or closed for many times still without screaming. Petrov was surprised that AAK engineer found and solved the problem of hydraulic relief valveS at one time, while the original Russian hydraulic relief valve manufacturer can do nothing? Because the scream of pilot operated relief valve is often generated by high-pressure oil through damping hole or valve port, AAK engineer added inclined hole of valve seat and vibration elimination cavity in the original design. In this way, the dynamic and static characteristics of the hydraulic pilot operated relief valve can be improved, the screaming can be eliminated, the noise can be reduced, and the pressure control accuracy can be improved at the same time. AAK strong engineering team not only has the concept of German HAWE, but also has the experience of Italian Oil Control，the problem can be found at one time. After the successful test run, Petrov privately told us that the boss was very satisfied that he found a strong manufacturer of hydraulic relief valves this time, which not only solved the problems that the original Russian manufacturer could not solve, but also made the price 30% cheaper. AAK will be his first choice for the test order of hydraulic relief valves in the future. AAK hydraulic relief valves, super technical team, you can also have a small try!
