      Piston hydraulic cylinder can be divided into single-rod and double-rod two structures, the fixed way by the cylinder fixed and fixed piston rod two, according to the role of hydraulic pressure has a single role and double-acting. In a single role In the hydraulic cylinder, the pressure oil is only provided in a cavity of the hydraulic cylinder, which realizes unidirectional movement of the cylinder by hydraulic pressure and external force (such as spring force, self-weight or external load) in the opposite direction; and the double-acting hydraulic cylinder piston movement in both directions alternately into the two chambers through the oil, the role of hydraulic pressure to complete, it is only one side of the piston with a piston rod, so the effective area of ​​the two chambers are different. In the oil the same amount, the different chamber into the oil, the piston speed of movement is different; in the same load force to be overcome, the different chamber into the oil, the required oil pressure is different, or set in the system pressure, sanitation Garbage truck hydraulic cylinder movement in both directions can overcome the load force is different.

Special Non-standard large diameter, long stroke hydraulic cylinder can customized for you.

● High pressure, high strength, lightweight miniaturization - design of the cylinder body and piston rod, material selection and processing technology, welding technology, are based on the analysis of the load frequency of the cylinder, the optimized strength,

Fatigue parameters, non-destructive testing by ultrasonic inspection, to achieve high-strength fuel tank, lightweight miniaturization.                                                                                                                               

● Sealing system - choose PARKER, MERKEL, NOK and other imports of high-end seal, combined with the company's unique sealing system design to prevent sand and dust, reduce oil leakage, access to the best piston rod film.

● Cylinder - Cylinder body made according to suitable strength and size, the inner surface of which is processed by rolling to improve the surface hardness and abrasion resistance while ensuring the dimensional accuracy and roughness.

● Piston rod - based on high-frequency quenching, has been coated with a hard chrome surface to improve rust, abrasion and damage resistance. Surfaces obtained after precision polishing have a uniform texture and high finish to ensure Good surface oil film, improve product life.

● Buffer / Safety Functions - Built-in cushioning mechanism that absorbs impact at the stroke end, as required, and also allows easy installation of various valves with functions such as slow return, balance and emergency shutdown.
