Product Description
As a highly specialized hydraulic cylinder manufacturer, we have provided design optimization solutions and reliable products to over 500 domestic and foreign customers. No matter in engineering machinery, railway bridge machinery, port marine machinery, metallurgical mining machinery, petroleum light industry machinery, special vehicles and other industries, we can provide all kinds of standard and non-standard fuel tank design optimization solutions and products according to user needs. Provide perfect quality integrated services.
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.
1. 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,
2. Fatigue parameters, non-destructive testing by ultrasonic inspection, to achieve high-strength fuel tank, lightweight miniaturization.
3. 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.
4. 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.
5. 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.
6. 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.
Processing and inspection:
1) Sealing system
All the hydraulic cylinders produced by our company adopt the seal ring products of Hallite,NOK,SKF,Parker,Merker,Trelleborg,China made,Taiwan made
2) Piston rod
The piston rod is made of high strength carbon steel with precision grinding treatment. With the design concept of improving the rod strength and the high performance heat treatment, hard chrome plating and CNC tumbling, the even veins and high degree of finish of the surface is guaranteed, and it has good oil membrane at the surface, which improves the service life of the seal parts.
3) Guide sleeve
The sleeve is made of high strength spheroidal graphite cast iron and high strength steel under buffering inner bore copper welding treatment.
4) Piston and piston seals
The standard piston is of one-piece steel structure. The firm lock-up between the long screw thread and the steel ball is convenient for the installation and it also guarantees the reliable operation under high speed load. New design of screwing parts greatly improved the cross section where the piston rod bears the axial load and improves the strength of piston rod to the maximum.
