(Panama sanitation truck hydraulic cylinder,produced by Hengyu Group）

sanitation truck hydraulic cylinder are widely used in Panama，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed sanitation truck hydraulic cylinder for customers from Panama.

Introduction to sanitation truck hydraulic cylinder:

What kind of process is used in the sanitation truck hydraulic cylinder to make high-quality sanitation truck hydraulic cylinder products: the body is the main component of the sanitation 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 sanitation 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 sanitation 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 sanitation truck hydraulic cylinder increases by 25%. If the service life of the sanitation 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. sanitation 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 sanitation 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 sanitation truck hydraulic cylinder are stuck or the sanitation truck hydraulic cylinder is blocked. At this time, no matter how to manipulate, the sanitation 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 sanitation truck hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

If the piston rod and sanitation truck hydraulic cylinder are stuck or the sanitation truck hydraulic cylinder is blocked, at this time, no matter how to operate, the sanitation truck hydraulic cylinder does not move or has little action. 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 sanitation truck hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The piston rod and guide sleeve function of the sanitation truck hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

When the sanitation truck hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the sanitation truck hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

Answers to some questions about sanitation truck hydraulic cylinder:

What size of hydraulic cylinder is needed for 200 tons pressure? The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate by the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the pressure level P (unit MPa) when working, then the thrust of the cylinder F push =3.14*R*R*P (unit N) the pull of the cylinder F pull =3.14* (R* R-R *R) *P (unit N) 100 tons of the cylinder, System pressure 16Mpa.

Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.
