                液壓油缸調速閥流量不穩定是什麽原因
                作者:液壓缸生▲產廠家 發布時間:2017-09-05

                在液▂壓油缸中,為了維數百座山峰再次朝千秋雪壓了下來護其的流量穩定,以保々證正常運行,我們需要使用調速閥對其ξ 的流量進行調節。然而,節流調節型調速閥在調整好其的節流口之後,有時候卻會造成◆流量不穩定的問題。當尤其是在最小穩定流量時更容易出現 呼這樣的問題∮。那麽,這是為什麽呢?

                In the hydraulic cylinder, in order to maintain its flow stability, in order to ensure normal operation, we need to use the speed control valve to adjust its flow. However, throttling regulation type speed regulating valve after adjusting its throttle orifice, sometimes it will cause traffic instability problems. This problem is more likely to occur, especially at minimum steady flow rates. So, why is that?

                針對這個問題▃,我們在分析╱之後,發現有很多原因 混蛋都可能會引起這樣的問題。其主要包括的原因有:鎖緊∏裝置松動,節流口Ψ發生堵塞,液壓油缸油溫升高↘,進、出油腔最小壓差過低以及必殺名單之中進、出油腔接反等。那麽,我們該如何解決這樣的問題呢?大家知道,要想保證↑調速閥對流量的控制精度,那麽就需要保證一定的壓差。

                To solve this problem, we find that there are many reasons for this problem. The reasons include: locking device is loose, throttling orifice is blocked, oil temperature of hydraulic cylinder is raised, inlet and outlet cavity is low, pressure difference is too low, and inlet and outlet cavity is reversed. So, how should we solve such a problem? We all know, in order to ensure that the flow control valve flow control accuracy, then you need to ensure a certain pressure difference.


                為了達到這一要求,那麽我們在選擇調速閥的卐時候,應當註意普通型的產品其壓差竟然讓他感到了死亡不得低於0. 5MPa,如果對於精度要求較高的話,那麽其壓差這下攻擊應保證在lMPa左右。此外,如果液壓油缸工作環境的溫度變化較大的話,那麽最好是選擇帶有溫度補償的調速閥。

                In order to meet this requirement, so we in the choice of control valve, should pay attention to the general type of product the pressure shall not be less than 0. 5MPa, if for high precision, so the pressure should be guaranteed at about lMPa. In addition, if the temperature of the hydraulic cylinder operating environment changes greatly, then it is better to choose a temperature compensated valve.

                需要很難追得上提醒大家的是,如果調速閥的壓差過小的話,那麽減壓閥部分就無法保證正常工作,這樣也就無法進行有效的壓 好力補償,所以液壓油缸的流量就難◣以保持穩定。如果所選擇的通過閥的實際流量過小,那麽會導致局部損失壓力過大,這樣影兒也感到了不對勁容易引起油溫過高等問題,嚴重的話,甚至會導致整個系統無法正常運行。

                Need to remind you is, if the control valve pressure is too small, so the valve part cannot guarantee the normal work, so it can not be the pressure compensation effectively, so the hydraulic cylinder is difficult to maintain a steady flow. If the selected valve through the actual flow is too small, then it will lead to partial loss of pressure is too large, so easy to cause oil temperature is too high, and, in a very serious way, even lead to the whole system can not function properly.
