(Germany sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

sanitation truck hydraulic cylinder are widely used in Germany，because of long service life，smooth movement，high work efficiency.So our company has designed sanitation truck hydraulic cylinder for customers from Germany.

Introduction to sanitation truck hydraulic cylinder:

The sanitation truck hydraulic cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the sanitation truck hydraulic cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the sanitation truck hydraulic cylinder wall due to the stiffness and the weight of the parts, causing scars.

sanitation truck hydraulic cylinder installation precautions: Before installing the sanitation truck hydraulic cylinder into the system, the parameters on the sanitation truck hydraulic cylinder label should be compared with the parameters when ordering. The base of the sanitation truck hydraulic cylinder must have sufficient stiffness, otherwise the sanitation truck hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

When the sanitation truck hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The sanitation truck hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the sanitation truck hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil sanitation truck hydraulic cylinder should not be in direct contact with water vapor for a long time. The sanitation truck hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the sanitation truck hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the sanitation truck hydraulic cylinder Before working, the sanitation truck hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the sanitation truck hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Disassembly sanitation truck hydraulic cylinder: When disassembly sanitation truck hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the sanitation truck hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the sanitation truck hydraulic cylinder.

Answers to some questions about sanitation truck hydraulic cylinder:

Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.

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!
