申博sunbet客户端调速阀流量不稳定是什么原因

发表时间:2017-07-08 18:50  责任编辑:申博sunbet官网设备  点击: 次

  在申博sunbet客户端中,为了维护其的流量稳定,以保证正常运行,我们需要使用调速阀对其的流量进行调节。然而,节流调节型调速阀在调整好其的节流口之后,有时候却会造成流量不稳定的问题。当尤其是在最小稳定流量时更容易出现这样的问题。那么,这是为什么呢?

  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?

  针对这个问题,我们在分析之后,发现有很多原因都可能会引起这样的问题。其主要包括的原因有:锁紧装置松动,节流口发生堵塞,申博sunbet客户端油温升高,进、出油腔最小压差过低以及进、出油腔接反等。那么,我们该如何解决这样的问题呢?大家知道,要想保证调速阀对流量的控制精度,那么就需要保证一定的压差。

  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.

  为了达到这一要求,那么我们在选择调速阀的时候,应当注意普通型的产品其压差不得低于0. 5MPa,如果对于精度要求较高的话,那么其压差应保证在lMPa左右。此外,如果申博sunbet客户端工作环境的温度变化较大的话,那么最好是选择带有温度补偿的调速阀。

  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.

  需要提醒大家的是,如果调速阀的压差过小的话,那么减压阀部分就无法保证正常工作,这样也就无法进行有效的压力补偿,所以申博sunbet客户端的流量就难以保持稳定。如果所选择的通过阀的实际流量过小,那么会导致局部损失压力过大,这样容易引起油温过高等问题,严重的话,甚至会导致整个系统无法正常运行。

  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.
