(Czech Republic vehicle hydraulic cylinder,produced by Hengyu Group)

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

Introduction to vehicle hydraulic cylinder:

In order to ensure the service life of the vehicle hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

When the vehicle hydraulic cylinder is installed, the piston and the vehicle hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the vehicle hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the vehicle hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized vehicle hydraulic cylinders, only careful and careful operation can be avoided.

vehicle hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the vehicle hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The vehicle hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the vehicle hydraulic cylinder, bite. Elimination method: When installing the vehicle hydraulic cylinder, ensure that the axis position of the vehicle hydraulic cylinder is consistent with the direction of movement; Make the load borne by the vehicle hydraulic cylinder as far as possible through the vehicle hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about vehicle hydraulic cylinder:

How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.

What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!
