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

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.

The bell of the New Year has just rang. As Vientiane is renewing, in order to further enhance the company's sustainable development momentum, Zhongshan Wanda Machinery Automation Technology Co., Ltd. actively made plans and worked hard on February 6, 2025 under the leadership of General Manager Yan Changrong. At the sales department meeting, General Manager Yan Changrong first conducted a comprehensive and detailed review of the company's sales in the past few years. He not only reviewed the sales performance growth curve every year, but also deeply analyzed the sales characteristics of each regional market and the sales performance of different product lines. Through in-depth exploration of past data, Mr. Yan has provided a solid basis and clear direction for the formulation of sales targets in 2025. He emphasized that the setting of sales targets must not only conform to the actual market situation, but also be challenging, and encourage all sales personnel to climb to the top.
