(Ecuador garbage truck hydraulic cylinder,produced by Hengyu Group）

garbage truck hydraulic cylinder are widely used in Ecuador，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed garbage truck hydraulic cylinder for customers from Ecuador.

Introduction to garbage truck hydraulic cylinder:

When producing oil garbage truck hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

What kind of process is used in the garbage truck hydraulic cylinder to make high-quality garbage truck hydraulic cylinder products: the body is the main component of the garbage truck hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The garbage truck hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the garbage truck hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the garbage truck hydraulic cylinder increases by 25%. If the service life of the garbage truck hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. garbage truck hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the garbage truck hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and garbage truck hydraulic cylinder are stuck or the garbage truck hydraulic cylinder is blocked. At this time, no matter how to manipulate, the garbage truck hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the garbage truck hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The definition of the minimum starting pressure of the garbage truck hydraulic cylinder refers to the minimum working pressure of the garbage truck hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the garbage truck hydraulic cylinder parts and the size of the sealing friction.

When the control pressure of the hydraulic system is too low, the garbage truck hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

Answers to some questions about garbage truck hydraulic cylinder:

How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.

How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.
