滕州众友重工液压机厂家生产的四柱液压机的优势：
1、The fuselage is a four-column structure, and the stress parts are optimized for design, beautiful appearance, and economical application.
2、The volume of the liquid filling tank is increased to ensure rapid liquid filling and reduce the pressure time. Increase the heat dissipation area and reduce the oil temperature.
3、The modulus of the end face of the three beams of the host is large, which improves the rigidity of the three beams and greatly extends the life.
4、The master cylinder and piston rod are made of high quality forgings, which improves the reliability.
5、The main rod adopts a four-nut structure, which improves the pre-tightening performance and can maintain the stability of accuracy for a long time.
6、The surface of the piston rod and the column is quenched and plated with hard chromium to improve the wear resistance and prevent surface corrosion and scratches.
7、The advanced cartridge valve is adopted, the structure is compact, the pipeline connection is reduced, the sealing of the system is improved, and the leakage is reduced.
8、The power system adopts oil immersed vertical pump set. Reduce noise, good oil absorption effect, improve the life of the pump.
9、The pressure gauge is shock-resistant and equipped with pressure gauge section for easy maintenance.
10、The main cylinder seal adopts imported domestic preferred parts.
11、电气控制系统有继电器和PLC二种控制方案供选择，由PLC控制的电气系统、工作灵敏可靠，柔性好；操作按钮集中于面板并设有活动按钮站，操作方便；具有调整，双手单次循环二种操作方式
12、滑块可实现定程、定压两种控制方式，具有保压、延时等功能；工作压力，行程大小可根据工艺需要在规定范围内可调。
