The working speed of the hydraulic press is significantly slower than the return speed. This is not because it is technically impossible to achieve high speed, but because it is an active design trade-off based on power balance and molding process requirements. The core logic revolves around the inherent constraints of the hydraulic system 'pressure-flow-power' and is combined with the core demands of its industry application scenarios. The following is a detailed analysis from the four dimensions of principle, difference comparison, design consideration and application adaptation: 1. Core principle: 'Power Balance Law' of the hydraulic system The operating speed of the hydraulic machine is directly determined by the flow rate of the hydraulic oil (the greater the flow rate, the faster the actuator is pushed), and the core constraint of the system comes from the power limit of the hydraulic pump. The relationship can be expressed intuitively through the formula: Pump power (P) = Working pressure (p) × Flow (Q) (Note: The formula is a simplified model, the actual system efficiency needs to be considered, but the core logic is the same) The rated power of the hydraulic pump is a fixed value (determined by the motor power), so 'pressure

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

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.

Thanksgiving comes, and we open a new chapter together - Our company debuts at the first Shanxi (Dingxiang) Flange Forging Industry Expo in July, and the forging industry is in full swing. The grand opening of the first Shanxi (Dingxiang) Flange Forging Industry Expo not only sets up a new platform for exchanges and cooperation for the industry, but also gives us the honor to gather at the booth with the leaders of the Shanxi Provincial Department of Commerce, the Dingxiang County People's Government and the Hubei Forging Association, draw strength to forge ahead through careful guidance and anchor the development direction in in-depth exchanges. This trust and affirmation is not only a recognition of our deep cultivation and forging of strength in the field, but also an expectation for us to take root in Shanxi and serve regional industrial upgrading. As active participants in the first expo, we are well aware of the milestone significance of this grand event - it is not only a concentrated display of the industrial heritage of Dingxiang' 'China's Forging Hometown' but also an important signal for Shanxi's forging industry to move towards high-quality development. From displaying technical achievements at the booth to the same as the industry

From April 23 to April 25, 2025, the highly anticipated Chengdu International Industrial Expo was grandly held in the Western China International Expo City! Our company is honored to participate and sincerely invites you to visit our booth. Our booth number is 16H - B097, and we look forward to meeting you at the exhibition site.
