Recently, Jiangsu Provincial Economic and Information Committee announced the 2015 Jiangsu Province Technical Transformation Demonstration Project. Wujin District Hengli Hydraulic Co., Ltd. listed the “Technical Transformation of Excavator High Pressure Cylinder Production Lineâ€.
Hengli Hydraulic “Technical Reconstruction of High-pressure Cylinder Production Line for Excavator†has a total investment of 300 million yuan. It introduces advanced CNC machining and other equipment, adopts advanced manufacturing technology, and improves the manufacturing capacity and quality of the cylinder to form an annual output of 120,000 excavators. The production capacity of special high pressure cylinders. Through the implementation of the project, the cylinders have significantly improved in performance, environmental protection, energy saving, quality reliability and service life, which largely meets the demand of high-quality high-pressure cylinders in domestic complete machine factories, and replaces imported oil cylinders to further consolidate the company in the construction machinery industry. Leading position in the excavator cylinder market.
In order to give full play to the demonstration and driving role of key technological transformation projects, encourage and guide enterprises to take the intensive development path and promote industrial transformation and upgrading. Jiangsu Province has carried out the identification of technical transformation demonstration projects since 2013. Confirmed.
Precautions for daily maintenance of hydraulic cylinders
1. Regularly inspect the sealing components of the hydraulic cylinder, such as O-rings and gaskets, to ensure that they are intact and undamaged. If there is wear or aging, they should be replaced in a timely manner.
2. Regularly check the liquid level of the hydraulic cylinder and keep it within the specified range. If the liquid level is too low, add hydraulic oil in a timely manner.
3. Regularly inspect the connection parts of the hydraulic cylinder, such as oil pipes and joints, to ensure their tightness and reliability. If there is any looseness, it should be tightened in a timely manner.
4. Regularly clean the outer surface of the hydraulic cylinder to prevent dust, sand, and other debris from entering the interior of the cylinder and affecting its normal operation.
5. Regularly inspect the surface of the piston rod of the hydraulic cylinder, and promptly repair or replace it if there are scratches or wear.
6. Regularly inspect the hydraulic system of the hydraulic cylinder, and promptly handle any problems such as oil leakage or unstable pressure.
7. When the hydraulic cylinder is not in use for a long time, its hydraulic oil should be drained to avoid oil aging, deterioration, and affecting the normal operation of the hydraulic system.
8. When repairing or replacing hydraulic cylinders, attention should be paid to safety to avoid sudden movement or pressure release of the hydraulic cylinder, which may cause personal injury or equipment damage.
