(Kazakhstan yg series hydraulic cylinder,produced by Hengyu Group）

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

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the yg series hydraulic cylinder head itself is the guide sleeve of the piston rod, the yg series hydraulic 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 yg series hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

When the yg series hydraulic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

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

In order to ensure the service life of the yg series hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about yg series hydraulic cylinder:

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
