trailer hydraulic cylinder are widely used in Poland，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed trailer hydraulic cylinder for customers from Poland.

Introduction to trailer hydraulic cylinder:

The piston rod and guide sleeve function of the trailer 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 purchasing the trailer hydraulic cylinder, try to clarify the following parameters of the trailer hydraulic cylinder: A. trailer hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or trailer hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right trailer hydraulic cylinder type can be found accurately and quickly.

Repair method of small range wear of oil trailer hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

When the trailer hydraulic cylinder is installed, the piston and the trailer 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 trailer hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the trailer 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 trailer hydraulic cylinders, only careful and careful operation can be avoided.

Answers to some questions about trailer hydraulic cylinder:

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
