(Sudan spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Sudan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed spring return cylinder for customers from Sudan.

Introduction to spring return cylinder:

spring return cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the spring return cylinder head itself is the guide sleeve of the piston rod, the spring return cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the spring return cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The definition of the minimum stable speed refers to the minimum movement speed of the spring return cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the spring return cylinder that undertakes different work has different requirements for the minimum stable speed.

spring return cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Answers to some questions about spring return cylinder:

What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.
