搅拌一体机制动后踏板复位慢的原因

搅拌一体机复位慢的表现是搅拌一体机在制动减速后,松开制动踏板,车速不能很快地提高,严重的甚难以起步,水泥搅拌一体机发生制动发咬的故障后,可以按如下步骤检查并排除:
The slow reset of the mixing machine is shown by the fact that the speed of the mixing machine can not be increased quickly after the brake pedal is released after the mixing machine is decelerated, and it is even difficult to start seriously. After the braking bite of the cement mixing machine occurs, the following steps can be taken to check and eliminate it:
1、如果踏板自由行程适当,主制动阀排气口有气体排出,挂档起步,如果能起步,行驶一段距离应检查制动鼓是否发热,如发热一般是由于制动蹄和制动鼓间隙太小所致。应检查制动蹄和制动鼓的间隙,使之保持正常。
1. If the free stroke of the pedal is appropriate, the gas is discharged from the exhaust port of the main brake valve. Shift the gear to start. If it can start, check whether the brake drum is hot after driving for a certain distance. If it is hot, it is generally caused by the small gap between the brake shoe and the brake drum. Check the clearance between the brake shoe and the brake drum to keep it normal.
2、如果不能起步,可踩下踏板,将变速杆置于空档,然后在松开制动踏板的同时,检查各制动气室的推杆能否回位。如果是某个制动气室的推杆不能回位,即是继动阀卡死,或是制动蹄回位弹簧太软,断裂造成的,或者是前制动蹄销锈死造成的。
2. If you can't start, step on the pedal, put the shift lever in neutral, and then check whether the push rod of each brake air chamber can return while releasing the brake pedal. If the push rod of a brake air chamber fails to return, that is, the relay valve is stuck, or the brake shoe return spring is too soft and broken, or the front brake shoe pin is rusted.
3、检查制动踏板的自由行程,或者是在贮气筒气压达到规定之后,踩下制动踏板,然后在松开踏板的同时检查主制动阀的排气口有无气体排出,如无气体排出,踏板无自由行程,说明是主制动阀的排气阀打不开,应调整主制动阀拉杆,使主制动阀的活塞杆和排气阀之间有正常的间隙,使制动踏板保持正常的自由行程。
3. Check the free stroke of the brake pedal, or step on the brake pedal after the air pressure in the air reservoir reaches the specified value, and then check whether the exhaust port of the main brake valve is discharged when the pedal is released. If there is no gas discharge, the pedal has no free stroke, which means that the exhaust valve of the main brake valve cannot be opened. Adjust the pull rod of the main brake valve to ensure that there is a normal gap between the piston rod of the main brake valve and the exhaust valve, Keep the brake pedal at normal free stroke.
此外热车在启动搅拌一体机之前,需要十多分钟的时间来起到制动的作用,而搅拌一体机的制动系统则是一个由发动机提供压力的推力钳夹住刹车盘(盘刹)或推力盘与刹车鼓之间的摩擦。所以,如上所述,可能是输油管道中的供油压力太低,导致不能及时提供制动力。检验制动总泵的真空助力器皮管及搅拌一体机车头处是否有脱皮、脱落现象。
In addition, it takes more than ten minutes for the hot car to brake before starting the integrated mixer. The brake system of the integrated mixer is a thrust clamp provided by the engine to clamp the brake disc (disc brake) or the friction between the thrust disc and the brake drum. Therefore, as mentioned above, it may be that the oil supply pressure in the oil pipeline is too low, resulting in failure to provide braking force in time. Check whether the vacuum booster leather pipe of the brake master cylinder and the head of the mixing integrated locomotive are peeled off.
The brake of the mixing machine does not return. When the brake pedal is pressed, the pedal does not rise and there is no resistance. This is the phenomenon that the brake does not return. It is necessary to judge whether the brake fluid is lost, whether the brake cylinder, pipes and joints leak oil, and whether the components of the master cylinder and the slave cylinder are damaged.
