Product Description
A double-acting cylinder is used in applications where:
Even with applications where gravity (or weight) can assist retraction, hydraulic pressure is often applied to double-acting cylinders to control acceleration, change the rate of travel and cushion the stoppage. Travel in one direction always differs from travel in the other, all things being equal; the push action requires more force and is slower, but more work output is generated. The pulling action is faster, but less work output is created.
Double-acting cylinders also act as a reservoir, because fluid flows under pressure to the piston side to extend the hydraulic cylinder. On the return stroke, the fluid flows under pressure to the rod side of the cylinder to retract it. The cylinder is therefore holding most of the fluid, so if you have a limited amount of space in your application, e.g. with DC hydraulic power units, you can effectively use a much smaller reservoir or tank to hold the oil.

Our QC technician will make quality control for every steps of long stroke hydraulic cylinder produce process. For finished long stroke hydraulic cylinder we make full inspection. The worker will inspect long stroke hydraulic cylinder by themselves and also by the member of the team. Our test content mainly including samples test,performance test,reliability test,disassemble test,endurance test.

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.
Product model
Hydraulic cylinder common problem:
1. Improper operation caused by the user cylinder or cylinder deformation (overturn, cylinder by external impact, the use of emergency brake unloading, etc.)
2. the cylinder bore internal fine particles produced after the arrest of the guide ring, causing chaos cylinder.
3. missing (welding) limit plate limit valve failure.
4. Limit valve internal failure caused by cylinder out of line.
5. To improve the trip, the user adjusts the limit valve stem without permission, causing the limit valve failure caused by dislocation of the cylinder rod or stuck.
6. Limit valve stem cannot return caused by fuel tank stuck.
Limit valve is to control the normal use of key components of the cylinder, once the failure, most likely to cause very serious consequences, can be summarized as: small parts, major faults. Please pay attention to the installation of parts inspection, and guide the user to use the proper maintenance.
First, we supply a wide rang of hydraulic cylinders such as HSG series,Y-HG series,YG series,DG series and so on.
Second,we provide all kinds of standard or nonstandard hydraulic cylinders.
Third,we supply custom processing service,we can make cylinders according to your descriptions,pictures,drawings or your samples.
But the information should be told as below:
stroke,working pressure,test pressure,pulling and return speed,the way to install,assembly size,working condition like temperature ,working frequency,tube and piston rod material requirement,surface treatment requirements and other related information.
I think our professional designers will meet your requirements. So pls contact us if you have any requirents.
