(Paraguay spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Paraguay，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed spring return cylinder for customers from Paraguay.

Introduction to spring return cylinder:

The difference between the integral spring return cylinder and the split spring return cylinder: The integral spring return cylinder and the split spring return cylinder in the spring return cylinder are two different spring return cylinders, and they are very different. The whole spring return cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split spring return cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and spring return cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The cavitation of the spring return cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the spring return cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

The quality of the spring return cylinder can not be ignored in the purchase of the spring return cylinder. The spring return cylinder is the main component of the spring return cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. spring return cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of spring return cylinder is deep hole processing, which has always troubled the processing personnel.

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.

Answers to some questions about spring return cylinder:

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
