混凝土主动上料搅拌车破坏后的维修事变

1、搅拌车聚散器破坏的缘由能源换挡变速器聚散器接应时,液压油的压力降服弹簧力压紧磨擦片。跟着液压油压力的降低,磨擦片与金属盘打仗并逐步压紧,使聚散器将飞轮能源安稳地通报到变速器输人轴。每次换挡时,磨擦片都要与钢片产生磨擦,产生的热量由冷却液披发进来。
1. When the power shift transmission clutch is engaged, the pressure of the hydraulic oil overcomes the spring force to press the friction plate tightly. With the increase of hydraulic oil pressure, the friction plate contacts with the metal plate and gradually compresses, so that the clutch smoothly transmits the flywheel power to the transmission input shaft. Every shift, friction plate and steel plate friction, heat generated by the coolant out.
当磨擦片及钢片变薄时,为了使它们充实接合就须要更多的液压油,发念头须进一步加快,磨擦片在钢片上的打滑时候也随之耽误,由此产生的磨擦热量也会更多,促使液压油的温度增添,当到达足以转变变速器中密封件机能的温度时,变速器就会产生内泄。而内泄又从两个方面持续引发热量的增添:高压油经破坏的密封处泄露,使油温持续降低;因为漏油,液压泵必将要保送更多的油液来保障接合聚散器时所需的压力,使聚散器充实地接合,这也请求发念头持续加快,使液压泵产生更大的流量。如斯恶性轮回,必将致使聚散器过热或烧损,直至完整生效。
When the friction plate and steel plate become thinner, in order to make them fully joint, more hydraulic oil is needed. The engine must be further accelerated, and the sliding time of the friction plate on the steel plate will also be prolonged, resulting in more friction heat, which will increase the temperature of the hydraulic oil. When the temperature is enough to change the performance of the seal in the transmission, the transmission will produce internal leakage. The internal leakage causes the increase of heat from two aspects: the leakage of high-pressure oil through the damaged seal makes the oil temperature continue to rise; Due to the oil leakage, the hydraulic pump will need to deliver more oil to ensure the pressure required to engage the clutch, so that the clutch can be fully engaged, which also requires the engine to continue to accelerate, so that the hydraulic pump can produce greater flow. Such a vicious circle will lead to overheating or burning of the clutch until it is completely invalid.

2、搅拌车聚散器活塞密封性的检测装载机行走有力或油温太高时,就须要判定是聚散器活塞密封不严仍是油压缺乏引发的,但惯例检测手腕偶然很难判定是哪一个缘由引发毛病,特别是在无能源的环境下,查抄组装好的变速器总成的各密封环就更坚苦了。此时,可接纳气压阀停止测试。
2. When the loader moves weakly or the oil temperature is too high, it is necessary to judge whether the clutch piston seal is not tight or the oil pressure is insufficient. However, it is sometimes difficult to determine which cause the fault by conventional detection methods, especially in the case of no power, it is more difficult to check the seal rings of the assembled transmission assembly. At this time, the pneumatic valve can be used for testing.
起首,将搅拌车变速器节制阀拆掉(对组装好的变速器应在装节制阀之前),而后顺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入口计量泵,则申明与之对应的聚散器活塞与缸筒间的密封杰出;若听不到活塞压紧磨擦片的声音且漏气声较大,则申明聚散器活塞与缸筒间的密封生效,应改换密封件。
First of all, remove the control valve of the mixer transmission (before installing the control valve for the assembled transmission), and then fill each oil hole of the transmission with 0.6-0.8mpa gas in turn. If the sound of "bang" is heard when a hole is filled with gas, and there is no air leakage or the air leakage is very small, then the seal between the clutch piston and the cylinder is good; If the sound of the piston pressing the friction plate is not heard and the air leakage is large, the seal between the clutch piston and the cylinder barrel is invalid, and the seal should be replaced.
