Basic introduction of hydraulic cylinder for mixer truck

Mixing truck hydraulic cylinder: There are two processing techniques for producing oil cylinders, grinding and rolling, with the latter being superior to the former. Rolling processing is a non cutting process that utilizes the plastic deformation of metal at room temperature to flatten the micro roughness of the workpiece surface, thereby changing the surface structure, mechanical properties, shape, and size. Therefore, this method can achieve both finishing and strengthening simultaneously, which cannot be achieved by grinding. The commonly used materials for the cylinder barrel of the oil cylinder are seamless steel pipes of sizes 20, 35, and 45. The steel pipes are polished or rolled to achieve a roughness requirement of within 0.4 μ m. Low pressure oil cylinders can use 20 gauge steel pipes, while high-pressure oil cylinders use 45 gauge steel pipes. When installing the oil cylinder, the axial ends of the cylinder cannot be fixed firmly. Due to factors such as hydraulic pressure and thermal expansion inside the cylinder, there is axial expansion and contraction. If the two ends of the cylinder are fixed, it will cause deformation of various parts of the cylinder. When disassembling and assembling hydraulic cylinders, it is strictly prohibited to use hammers to strike the cylinder barrel and piston surface. If there is damage to the cylinder hole and piston surface, it is not allowed to use sandpaper to polish, and it should be carefully polished with a fine oilstone. The clearance between the guide sleeve and the piston rod should meet the requirements. If the sealing components of the oil cylinder experience abnormal wear, check whether the speed control valve is adjusted improperly, causing excessive back pressure and improper installation of the sealing components or hydraulic oil contamination. Secondly, whether there are foreign objects entering during assembly and poor quality of sealing materials. The consequence is slow and powerless movement, and in severe cases, it can also cause damage to the piston and cylinder, resulting in the phenomenon of "pulling the cylinder". The solution is to adjust the speed control valve and make necessary operations and improvements according to the installation instructions. During installation, it is necessary to ensure that the direction of the connecting head at the top of the piston rod is consistent with the direction of the cylinder head, earring (or middle hinge shaft), and to ensure the straightness of the entire piston rod during the process of advancing and retreating, in order to prevent rigid interference and unnecessary damage.

Reference price for hydraulic cylinder of mixer truck

The price of hydraulic cylinders for mixer trucks is determined by factors such as temperature requirements, frequency of use, thrust size, and system pressure. The price varies depending on whether pressure maintenance is required. The cost of hydraulic cylinders for common brands of mixer trucks ranges from 900/yuan to 5000/yuan.

Maintenance and related issues of hydraulic cylinder for mixer truck

• Oil leakage and treatment methods of CNC lathe rotary hydraulic cylinder
  Especially during the installation of hollow hydraulic cylinders, oil leakage often occurs. Firstly, check the deflection of the hydraulic cylinder, which must reach or approach the required value. Generally, Taiwanese hydraulic cylinders require an outer circular runout of less than 1 thread. Otherwise, if there is too much jumping, there will definitely be oil leakage. Then check if the oil pipe is smoothly descending at a certain slope and cannot bend. Take another look at the outlet of the oil pipe, it should not be submerged in the oil level, it should be slightly higher. Otherwise, there will be oil leakage even if there is back pressure.
• The reason why the hydraulic cylinder cannot be retracted after reaching its limit.
  Have you ever disassembled and inspected it? It may be caused by long-term use to the extreme position, leading to severe wear and tear! The solution is to add a travel switch or remove the gasket before and after the piston
• Hydraulic cylinder self-locking
  Hydraulic cylinder self-locking is divided into oil circuit self-locking and mechanical self-locking. The oil circuit is equipped with valves to maintain pressure, so that the hydraulic oil in the hydraulic cylinder does not return to the oil tank, and the hydraulic cylinder oil chamber is filled with a certain pressure of oil. But this pressure retaining self-locking is not very safe and reliable, and if there is a leak, the plunger will slowly return to its original position. Mechanical self-locking refers to the installation of a nut on the plunger of a hydraulic cylinder. When the hydraulic cylinder rises to the required position, the nut on the plunger of the hydraulic cylinder is rotated to the bottom and comes into contact with the cylinder body, so that the plunger is fixed to the required height. When pressure relief is required, screw the nut back on to allow the plunger to return to its original position. This type of hydraulic cylinder has a special name, called a self-locking hydraulic cylinder, which industry insiders know when you ask.
• Urgent, there is a sound coming from the hydraulic cylinder of the excavator boom. I don't know what the reason is
  The hydraulic cylinder of a hydraulic excavator includes three main parts: boom hydraulic cylinder, boom hydraulic cylinder, and bucket hydraulic cylinder, with four major hydraulic cylinders. The sound of the boom hydraulic cylinder may be due to wear of the cylinder body liner, piston rod liner, and shaft pin. The main reason is poor lubrication, followed by improper clearance during assembly. Countermeasure: (1) Strictly implement the lubrication of each axle pin at least once every 8 hours during the initial 100 hours of use and harsh working conditions of the excavator; Under other operating conditions, it is required to lubricate each shaft pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Strict adherence to assembly inspection standards and procedures is required when assembling and replacing various shaft pins and bushings
