Forklift Hydraulic Lift Cylinder

The piston hydraulic cylinder can be divided into two structures: single -pole and double -rod type. The fixed method is fixed by the cylinder body and the piston rod is fixed. The action of the hydraulic pressure has a single action type and dual action. In a single -acting hydraulic cylinder, the pressure oil is only one cavity of the hydraulic cylinder, and the pressure of the cylinder can be achieved by the pressure of the cylinder. The movement of the two directions of the hydraulic cylinder piston piston is alternated by the two cavity, and the pressure of the hydraulic pressure is completed.

Do not drive the load while working

The main performance is inaccurate stop of piston rod, insufficient thrust, speed drop, unstable work, etc. The reasons are as follows:

(1) Internal leakage of hydraulic cylinder. Internal leakage of hydraulic cylinder includes leakage caused by excessive wear of hydraulic cylinder seal, piston rod and seal cap seal and piston seal.

The reason for the seal leakage between the piston rod and the seal cap is that the seal is wrinkled, squeezed, torn, worn, aging, deteriorated, deformed, etc. At this time, the new seal should be replaced.

The main reason for excessive wear of piston seals is improper adjustment of speed control valves, resulting in excessive back pressure and improper installation of seals or contamination of hydraulic oil. The second is the assembly of foreign body into the sealing material quality is not good. Its consequence is the action is slow, weak, serious also can cause the piston and cylinder cylinder damage, appear "cylinder" phenomenon. The treatment method is to adjust the speed control valve, according to the installation instructions should do the necessary operation and improvement.

All parameters can be customized

Parameters of the sample

HCIC has a professional product quality test during the production process. These include the cylinder friction test of the hydraulic cylinder, the shock durability test, the drift rate test, the circulation test and the pressure test (the rated pressure is 150%in 5 minutes). The hydraulic cylinder test system is divided into single -acting and dual -action tests. When 100 % complete the test, they will be transferred to the quality inspection department for the final quality inspection link, and finally paste the label to put the market.

After years of efforts and investment, we have become a leader in the hydraulic cylinder industry. Our partners are well-known hydraulic cylinder brands from the United States, Canada, Australia, Germany, the United Kingdom and other European countries. Product quality, shorter delivery time and customer satisfaction are our long-term commitments to global customers. I hope to be your partner.

There are foreign bodies mixed in the cylinder：

Among the faults of the hydraulic cylinder, the most problematic is that it is not good to judge when the foreign body enters the hydraulic cylinder. After the foreign body enters, the outer side of the sliding surface of the piston is equipped with a seal with lip edge. Then, the lip edge of the seal can be scraped when working, which is beneficial to avoid scratch. However, the two ends of the piston with the O-shaped seal ring are sliding surfaces, and the foreign body is sandwiching between the sliding surfaces, which is easy to form scars.
