1、混凝土自上料搅拌车液压缸装配时端盖装偏,活塞杆和缸筒不同心,导致活塞杆伸出困难,加速密封件磨损。可以拆开检查,重新装配。
1. When the hydraulic cylinder of concrete self loading mixer is assembled, the end cover is biased, and the piston rod and cylinder are not concentric, which makes it difficult for the piston rod to extend and accelerates the wear of the seal. It can be disassembled for inspection and reassembled.
2、密封件安装差错:例如密封件装错或漏装。
2. Seal installation error: for example, the seal is installed wrong or missing.
①密封压盖未装好,不能压紧:如压盖安装有偏差、紧固螺钉受力 不均、紧固螺钉过长等。应该按对角顺序拧紧各螺钉,拧紧各螺钉时要受力均匀一致,按找螺孔深度合理选配螺钉长度。
① If the gland is not installed properly, it cannot be pressed tightly: for example, the gland is installed with deviation, the fastening screw is stressed unevenly, and the fastening screw is too long. The screws should be tightened in diagonal order, the force should be uniform when tightening the screws, and the screw length should be selected according to the depth of the screw hole.
②査密封件质量是否有问题:当反复更换新密封圈均解决不了 漏油问题时可能属于这种情况。此时应确认密封圈是否购自非正规厂家的产品,密封材质尺寸是否有问题密封件是否保管不善自然老化 变质。
② Check whether there is a problem with the quality of the seal: this may be the case when the oil leakage can not be solved by repeatedly replacing the new seal ring. At this time, it should be confirmed whether the seal ring is purchased from the irregular manufacturer's products, whether there is a problem with the size of the seal material, and whether the seal is not properly kept and naturally aged.
③查密封部位的加工质量是否符合要求:如沟槽尺寸及精度不 符合要求、密封表面粗糙、未倒角等,应按有关标准设计加工沟槽尺寸,不符合要求的要修正到要求的尺寸,修正并去毛刺。
③ Check whether the processing quality of the sealing part meets the requirements: if the groove size and accuracy do not meet the requirements, the sealing surface is rough, and there is no chamfer, the groove size shall be designed and processed according to the relevant standards. If the groove size does not meet the requirements, it shall be corrected to the required size, corrected and deburred.

④查混凝土自上料搅拌车液压缸密封件的使用条件:如油不清洁、黏度过低、油温过高、周围环境温度太高等,分别采取更换适宜的干净油液、査明温升原因,采取隔热、设置油冷却装置等措施。
④ Check the service conditions of the hydraulic cylinder seal of the concrete self loading mixer: if the oil is not clean, the viscosity is too low, the oil temperature is too high, and the ambient temperature is too high, take appropriate clean oil replacement, find out the cause of temperature rise, take heat insulation, set oil cooling device and other measures.
3、选择液压油缸的时侯,根据实际需要,在满足内径、行程、使用压力和安装形式的基本要求后,还应特别注意:
3. When selecting the hydraulic cylinder, according to the actual needs, after meeting the basic requirements of inner diameter, stroke, service pressure and installation form, special attention should be paid to:
①液压油缸承受负载后,如果其输出速度达到一定的标准,为了减少液压缸高速运动中忽然停止所产生的液压冲击,则必须选用带有缓冲装置的液压缸;速度更高的,还需在液压缸外加减速阀。
① If the output speed of the hydraulic cylinder reaches a certain standard after bearing the load, the hydraulic cylinder with buffer device must be selected in order to reduce the hydraulic shock caused by the sudden stop in the high-speed movement of the hydraulic cylinder; Higher speed, but also in the hydraulic cylinder speed valve.
②对于行程超过lOOOmm的液压缸,为了防止活塞杆过载及活塞过快磨损,应该使用支撑环。
② For the hydraulic cylinder with stroke more than 100 mm, in order to prevent overload of piston rod and rapid wear of piston, support ring should be used.
③一般来说,不同的液压油适用于不同材质的油封,选择液压油或油封时应注意密封材料与液压油和工作温度的关系,从而保障混凝土自上料搅拌车液压缸的寿命。
③ Generally speaking, different hydraulic oils are suitable for oil seals of different materials. When selecting hydraulic oil or oil seal, attention should be paid to the relationship between sealing material and hydraulic oil and working temperature, so as to ensure the service life of hydraulic cylinder of concrete self loading mixer.
