(Congo vehicle hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

vehicle hydraulic cylinder are widely used in Congo，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed vehicle hydraulic cylinder for customers from Congo.

Introduction to vehicle hydraulic cylinder:

The piston rod and guide sleeve function of the vehicle 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 long-stroke vehicle hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in vehicle hydraulic cylinder head seal damage, oil leakage, and piston sleep in the vehicle hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the vehicle hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.

Do not regularly check the damage of the chrome layer of the vehicle hydraulic cylinder: completely extend the vehicle hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the vehicle hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the vehicle hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the vehicle hydraulic cylinder.

The cavitation of the vehicle hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the vehicle hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

Answers to some questions about vehicle 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.

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.
