(India spring return cylinder,produced by Hengyu Hydraulic Co., Ltd）

spring return cylinder are widely used in India，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed spring return cylinder for customers from India.

Introduction to spring return cylinder:

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular spring return cylinder action. Troubleshooting method: Replace the rubber hose.

When installing the spring return cylinder pipe, the pipe should be cleaned after installation, and should not pass through the spring return cylinder block, and the by-pass pipe must be installed in front of the oil port of the spring return cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the spring return cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the spring return cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

spring return cylinder is the most important part of construction machinery, the traditional processing method is: broaching spring return cylinder block - fine boring spring return cylinder block - grinding spring return cylinder block. The rolling method is: broaching spring return cylinder block - fine boring spring return cylinder block - rolling spring return cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the spring return cylinder block is about 1-2 days, rolling 1 meter of the spring return cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the spring return cylinder increases by 25%. If the spring return cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality spring return cylinders, you must take the rolling production process. After the spring return cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Protection of the spring return cylinder surface: During the dismantling process, safety protection should be carried out on the spring return cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the spring return cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the spring return cylinder should be cleaned up in time.

Answers to some questions about spring return cylinder:

What is the problem that the cylinder stroke is not in place?
1. Mechanical cause: the piston rod bends; If there is a synchronous cylinder, the stroke of the two cylinders may be different. 2. Hydraulic reason: the system back pressure is too large; The actuator load increases while the system pressure decreases. The electric is not sent, the reversing valve is not reset or stuck, the oil is too dirty, there is gas in the system, the external inertia load is too large, and the cylinder stroke is not in place.

What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
