Hazards of excessive temperature of servo hydraulic press 1. The temperature of the servo hydraulic press itself is too high, which reduces the viscosity of the oil and the leakage increase, and the efficiency of the system and the capacity base of the pump will be reduced. The oil film of moving parts such as slide valves will become thinner and produces greater friction resistance, resulting in increased wear and affects the inability to operate the machine. 2. The temperature of the equipment is too high, causing it to deform itself. Different moving parts in the hydraulic components have different degrees of thermal expansion, which will cause jamming due to the small gap between them at the same time, thus reducing the working efficiency of the servo hydraulic press. 3. Excessive temperature causes the service life of hydraulic oil to be greatly reduced, blocking the gap between the small holes, causing the pressure valve to not work normally. 4. Excessive temperature rise causes the rubber seal to deform, accelerate the aging degree, and cause leakage. 5. The excessive temperature reduces the air separation pressure of the oil, resulting in a decrease in the working performance of the hydraulic system. Therefore, we must follow the different load requirements of the servo hydraulic press and enter it

When a failure of the hydraulic press cannot rise, it usually manifests as if the pressure-regulating handwheel is fully tight, the pressure can only rise to a certain value and cannot continue to rise, especially when the oil temperature is high, which is particularly obvious. So what are the reasons for the pressure not rise? 1. Check whether the cartridge valve and the reversing valve are stuck 2. Check the circuit failure, which may be the main reason for the inability to rise under normal circumstances. It is recommended to use a screwdriver to stab the small reversing valve to see if it is stuck, and then check whether the indicator light of the rising small valve is on. 3. The main relief valve in the four-column press system is worn seriously, causing overflow and debris, which is why it is stuck. 4. The flush valve on the upper part of the oil cylinder is not opened, so it cannot rise under normal circumstances. 5. Check whether the oil cylinder is broken. 6. Whether the four-column press system is adjusted and balanced and stuck the beam, of course, there are not many such problems. 7. Total pump flow

Professor Chen from Nanjing University of Technology and his party visited our company to conduct in-depth exchanges on the ultra-high pressure wire winding hydraulic press technology project. The two sides discussed in-depth key issues such as breakthrough in technological research and development bottlenecks and future cooperation directions, laying a solid foundation for promoting the innovative application of this technology in the industrial field.

You can use the following methods to determine whether the oil filter of the oil press is blocked: 1. Observe the appearance of the oil filter: Check the oil filter housing. If there is obvious accumulation of sludge and dirt, or there is obvious oil stain attachment in the inlet and outlet pipelines of the oil filter, it may imply that the oil filter is blocked. In addition, some oil filters have clogged indicators that indicate that the oil filter is clogged when the indicator shows a red or a warning sign pops up. 2. Feel the oil temperature change: blockage of the oil filter will cause the oil to flow poorly, causing the system to heat up and the oil temperature to rise. Therefore, if it is found that the oil temperature rises faster than usual during normal operation of the oil press, or the oil temperature is significantly higher, consider whether the oil filter is blocked. However, the increase in oil temperature may also be caused by other reasons, such as cooling system failure, and comprehensive judgment is required. 3. Check system pressure: Blockage of the oil filter will increase oil flow resistance, resulting in system pressure drop or instability. If the hydraulic press is working

At present, it is the peak period for mosquito-borne infectious diseases such as chikungunya fever. In order to effectively prevent and control mosquito-borne diseases such as chikungunya fever and dengue fever, and to ensure the health of the people, the party organizations in Banfu Town have taken active actions. The Bada Party Branch actively responded to the call. From late July to early August, it organized party member volunteers to participate in chikungunya fever prevention and control and human settlement environment improvement volunteer activities, contributing to protecting residents' health. On July 28, party member volunteers from Bada Branch went to Huzhou Village to carry out prevention and control volunteer activities. During the event, volunteers found that some residents had piles of wooden huts and wet wooden huts in their homes. These hidden and humid environments are very likely to become breeding grounds for mosquitoes. Volunteers worked together to help residents rectify these areas, pick and remove some houses with hidden dangers, reduce mosquito habitats from the source, and reduce the risk of mosquito-borne infectious diseases.

On August 8, a significant donation ceremony for mosquito media prevention and control materials was held in our town. With heavy love, the Banfu Branch of Zhongshan City Personal Association donated a batch of prevention and control materials to our town, injecting strong impetus into the prevention and control of chikungunya. Ni Xiaoping, deputy secretary of the town party committee and mayor, and Huang Zhimin, deputy mayors and Ou Yanting attended the donation ceremony and witnessed this warmth and responsibility together. At present, the prevention and control of chikungunya is in a critical period, which is affecting the hearts of all sectors of society. In order to promptly solve the demand for prevention and control materials, the Banfu Branch of Zhongshan Personal Private Association quickly responded to the call of the town party committee and government for prevention and control work, and issued an initiative as soon as possible to widely gather members' strength to participate in the prevention and control work of mosquito media. Among the many positive response forces, Zhongshan Wanda Machinery Automation Co., Ltd. and its affiliated Bada Party Branch performed particularly well.
