混凝土搅拌车损坏后该怎么办?

来源:http://www.leemeasure.com/ 时间:2022-03-14

混凝土搅拌车的出现和使用,能够为各类工程施工供给了诸多的便当,这些都是自动上料搅拌车的功劳,在使用的程度上提升了该设备的作业效率。使用人员要想保障自动上料搅拌车的使用功能,其中,一个重要的配件便是变速器换挡机,每一种配件使用时刻长了,都会出现一些问题,在它损坏后如何进行维修呢?跟着小编一起来了解一下吧。
The emergence and use of concrete mixer truck can provide a lot of convenience for various engineering construction. These are the credit of automatic loading mixer truck, which improves the operation efficiency of the equipment to the extent of use. If users want to ensure the use function of the automatic feeding mixer, one of the important accessories is the transmission shifter. If each accessory is used for a long time, there will be some problems. How to repair it after it is damaged? Follow Xiaobian to learn about it.
1、搅拌车离合器损坏的原因动力换挡变速器离合器接合时,液压油的压力克服绷簧力压紧冲突片。跟着液压油压力的升高,冲突片与金属盘触摸并逐步压紧,使离合器将飞轮动力平稳地传递到变速器输人轴。每次换挡时,冲突片都要与钢片发生冲突,发生的热量由冷却液发出出去。
1. The reason for the damage of the clutch of the mixer truck when the clutch of the power shift transmission is engaged, the pressure of the hydraulic oil overcomes the tension spring force to press the collision plate. With the increase of hydraulic oil pressure, the collision plate and metal plate touch and compress gradually, so that the clutch can smoothly transfer the flywheel power to the transmission input shaft. During each shift, the collision plate will conflict with the steel plate, and the heat generated will be sent out by the coolant.
当冲突片及钢片变薄时,为了使它们充分接合就需要更多的液压油,发动机须进一步加速,冲突片在钢片上的打滑时刻也随之延伸,由此发生的冲突热量也会更多,促使液压油的温度添加,当到达足以改变变速器中密封件功能的温度时,变速器就会发生内泄。
When the conflict plate and steel plate become thinner, more hydraulic oil is needed to make them fully engaged. The engine must be further accelerated, and the slip time of the conflict plate on the steel plate will also extend, resulting in more conflict heat, which will promote the temperature of the hydraulic oil to be added. When the temperature reaches the temperature sufficient to change the function of the seal in the transmission, the transmission will leak internally.
而内泄又从两个方面持续引起热量的添加:高压油经损坏的密封处走漏,使油温持续升高;因为漏油,液压泵势必要输送更多的油液来确保接合离合器时所需的压力,使离合器充分地接合,这也要求发动机持续加速,使液压泵发生更大的流量。如此恶性循环,必将导致离合器过热或烧损,直至彻底失效。
The internal leakage continuously causes the addition of heat from two aspects: the high-pressure oil leaks through the damaged seal, making the oil temperature rise continuously; Because of oil leakage, it is necessary for the hydraulic pump to deliver more oil to ensure the pressure required to engage the clutch and fully engage the clutch, which also requires the continuous acceleration of the engine and greater flow of the hydraulic pump. Such a vicious cycle will inevitably lead to overheating or burning of the clutch until it completely fails.
2、搅拌车的离合器活塞密封性的检测也很关键。装载机启动行走没有劲头以及油温过高时,就需要判断是离合器活塞密封不严还是油压缺乏引起的,但常规检测手法有时很难断定是哪个原因引起毛病,尤其是在无动力的情况下,查看拼装好的变速器总成的各密封环就更困难了。
2. The detection of the tightness of the clutch piston of the mixer is also very important. When the loader has no power to start and travel and the oil temperature is too high, it is necessary to judge whether it is caused by the loose sealing of the clutch piston or the lack of oil pressure, but it is sometimes difficult to determine which cause the problem by conventional detection methods, especially in the case of no power, it is more difficult to check the sealing rings of the assembled transmission assembly.
此时,可采用气压阀进行测验。首要,将自动上料搅拌车变速器控制阀拆掉(对拼装好的变速器应在装控制阀之前),然后依次给变速器各油孔通人0.6一0.8MPa的气体,若某一个孔通人气体时,听到"嘭"的一声且无漏气声或漏气声很小进口计量泵,则说明与之对应的离合器活塞与缸筒间的密封良好;若听不到活塞压紧冲突片的动静且漏气声较大,则说明离合器活塞与缸筒间的密封失效,应替换密封件。
At this time, the pneumatic valve can be used for test. First of all, remove the control valve of the transmission of the automatic feeding mixer truck (for the assembled transmission, it should be before the control valve is installed), and then fill each oil hole of the transmission with 0.6-0.8mpa gas in turn. If a hole is filled with gas, a "bang" sound is heard without air leakage sound or the air leakage sound is very small, It indicates that the seal between the corresponding clutch piston and cylinder barrel is good; If you can't hear the movement of the piston pressing the collision plate and the sound of air leakage is large, it indicates that the seal between the clutch piston and the cylinder barrel is invalid and the seal should be replaced.
