Shandong Tsinfa company independent research and development of 250 tons hydraulic press machine by the main frame and control system of two parts, through the pipeline and electrical devices connected to form a whole. The main frame includes fuselage, oil cylinder, limit device, etc. The control mechanism is composed of hydraulic press valve station, electric control box, operation table, etc. The 250 ton hydraulic press machine has a variety of structures and uses. Can be customized according to customer requirements, to achieve a multi-purpose machine. Help you save the purchase cost to the greatest extent. Many years of manufacturing experience can provide you with high quality hydraulic press machine. In the work of the hydraulic press machine, if the crawling phenomenon will have a great impact on the stability of the hydraulic system and machining accuracy (such as dimensional accuracy, positioning accuracy and surface roughness). Creeping phenomenon of the hydraulic press machine refers to the hydraulic cylinder at low speed when jumping or unstable motion state. So how does Creeping phenomenon come about? 1. There is air in the hydraulic cylinder. 2. Poor lubrication or uneven aperture of hydraulic cylinder. Hydraulic system operation is piston and cylinder, guide rail and piston rod relative movement, if there is poor lubrication or hydraulic cylinder aperture imbalance, will increase resistance to parts, aggravate wear. When working in the hydraulic cylinder, the piston will slip or crawl because of unstable frictional resistance. The elimination method is to repair the hydraulic cylinder, according to the requirements of the preparation of piston, repair grinding piston rod and guide sleeve orientation configuration. 3. Improper selection of hydraulic oil. If the viscosity of hydraulic oil is too large, the operating resistance of the cylinder is too large, it will also cause the hydraulic press machine to crawl. 4. The quality of seals can also cause crawling. O-ring under low pressure will increase the friction resistance difference, than u-ring easy to crawl; U-type sealing ring surface pressure is proportional to the pressure, improve the sealing effect, but the difference between static and static friction resistance also becomes larger, also easy to cause sliding or crawling, the solution can use the supporting ring to maintain its stability. 5. In the oil intake throttle speed regulation system, there is no back pressure or insufficient back pressure of the hydraulic cylinder. When the external load changes, the cylinder speed changes. 6. The flow pulsation of the hydraulic pump is large, and the vibration of the relief valve causes the pressure pulsation of the system, so that the hydraulic oil fluctuates when the pressure of the hydraulic cylinder is input and causes crawling. We can see that the hydraulic press machine crawling phenomenon is likely to be caused by machine design and production defects or non-standard operation. Therefore, when buying hydraulic press machine, it is very important to choose a hydraulic press machine manufacturer with production experience and perfect after-sales service system. Tsinfa company has more than ten years of production experience and a strong production design team. It is the best choice for you to buy hydraulic press machine.
