Some concrete mixer truck maintenance knowledge

Concrete mixer truck, with the concrete to produce goods and the emergence and development, it solves the problem of goods transport concrete pouring from site to site preparation, and therefore an ideal means of transport ready-mixed concrete. Due to the massive use of concrete mixing truck, many users of daily use and maintenance know much, mixer and relatively poor working environment, coupled with the user pay attention to routine maintenance, causing some unnecessary trouble and economic loss, I hope the following introduction by the majority of the mixer can be the user's daily use and maintenance play some guidance, to improve the economic efficiency of some help. First, the hydraulic system used in various systems of concrete mixer truck, the hydraulic system is the most important and most delicate working parts, its use and maintenance is particularly important, a hydraulic motor mixer domestic manufacturers to use, brand hydraulic electric gear ring for concrete and cement mixer pump and reducer mostly imported parts, which configuration may vary. When you turn the lever to the left by the pump variables, the pump will start from a drain port, high-pressure tubing into the motor, the motor is rotated by another high-pressure tubing back into the pump; the greater the variable angle lever is rotated, the pump discharge of oil the more, the higher the motor speed, the rotation of the motor driven gear, so that the mixer's mixing drum can be achieved within a certain speed range continuously variable transmission and two steering and other hydraulic systems this same principle. For hydraulic system efficient, trouble-free operation, it is necessary to strengthen the maintenance in daily use, and in strict accordance with the instructions of the requirements to operate as required in a timely manner to the hydraulic oil and assistive devices (mainly filter) replacement In the oil change process should note the following:

1, the use of performance parameters to meet the requirements of hydraulic oil, never use already used hydraulic oil. 2, the best use for the 5-10 micron filter precision filter to the system when refueling refueling. 3, the host system (such as tubing, etc.), oil pump, motor housing before starting to be filled with hydraulic oil. 4, first-time users after every 500 hours and 2000 hours hydraulic oil and filters need to be replaced, you must use the manual recommended models of hydraulic oil and filter. Yantai region in late December 2004 a user during an oil change in mixer, add the hydraulic oil contains a very small amount of water, resulting in a low temperature in winter is not operated mixer mixing tube failure. When the user will open when I mixer for repair (the road takes about an hour of the time), the mixing tube and can operate normally, and upon inspection found that users in the oil change, the oil containing a small amount of water in the pump within ice, blocking the valve port, after a long journey fluid temperature of the water inside the melt pump, oil flow, the system returns to normal. Our staff will organize the hydraulic oil to replace the car, then none of these problems in the future use. Thus adding hydraulic oil to ensure the quality, not mixed other substances, otherwise it will cause unnecessary trouble and economic losses. high efficiency forced electric concrete cement mixer with lift Good maintenance, maintenance of the hydraulic system is a powerful guarantee reliable operation, the user should observe the work of the hydraulic system in daily use, abnormal should be promptly stopped and checked, do not be careless, to work sick, resulting in greater loss. Second, the use idler roller mixer truck is one of the main load-bearing parts, the weight of concrete mixing drum and its internal mainly by the roller and reducer support, and because of limitations of the site traffic, it is subjected to a force uneven, occasionally accompanied by impact. Therefore, to limit the mixing drum beat in order to reduce the impact on the roller, and now the model is added to the mix with a pull cylinder pull, in their daily work to strengthen the maintenance and repair of damage to the timely replacement and maintenance, in order to avoid adversely affect the life of the idler. In the work, pay special attention to inner roller bearing lubrication, appearing in service statistics roller corruption problems, mostly because there is no timely lubrication, resulting in roller bearing damage caused. Also note that the lock nut loose, tighten and always check to timely, otherwise will cause damage to roller bearings, resulting in unnecessary losses.

Third, the problem of uneven material discharge uniformity issue is one of the important indicators of mixer performance, which directly affects the quality of construction. When transporting concrete mixing drum rotational speed should be controlled in 2 ~ 5r / min, the larger slump in long distance or concrete during transportation, the material should be preceded by the rapid rotation of the mixing tube 5 to 10 laps, so the inside Concrete can stir such uniformity of the material will be greatly improved. If the way of concrete dehydration, water should be added to the site adjustments, and sufficiently stirred, of course, this situation should be avoided, since this would not guarantee the quality of concrete. Some users do not pay attention when using the controls during transport speed, too fast will increase fuel consumption, too little will result in concrete segregation. Therefore, it should be strictly in accordance with the requirements to control the rotational speed of the mixing tube to improve the delivery of quality concrete. Fourth, the drive shaft Use: concrete mixer truck working environment is harsh, vehicles in the process of sudden acceleration and deceleration is inevitable, so the use of the process should always check for loose joints, but also from time to time to shaft lubrication. hot sale hydraulic motor ring gear for concrete and cement mixer We are in the process of repair mixer, repeatedly received user feedback, the drive shaft with a few long cross shaft or shaft scrapped the entire root. In the inspection process, we found that this situation is due to the majority of users do not pay attention in a timely manner to the drive shaft lubrication caused by lack of the drive shaft when the grease, if not raised, it will cause the inner spider roll needle dry friction, so that the needle loss caused Oldham scrapped, and even cause the entire root of the drive shaft scrapped. In short, the key lies in the usual mixer in terms of care and maintenance, these aspects only mixers use should be noted that, in the specific use, the user should be in strict accordance with the instructions to operate the mixer, each connecting member asked each time every moment must be carefully checked and found the problem to stop in time to make the necessary maintenance and repair, the only way to make the mixer to create the best value for money
