Maintenance of the High-Speed Hydraulic Station's Hydraulic System

1. A ventilation fan can be installed in the hydraulic system of the high-speed hydraulic station to regulate its temperature, preventing the hydraulic oil from overheating during operation and helping to reduce energy consumption. 2. After a leak occurs, address the issue promptly to minimize unnecessary losses and prevent further damage. 3. Ensure proper installation of all components and secure connections within the pipeline system. Thoroughly seal the hydraulic station’s hydraulic system, replacing seals at regular intervals. Additionally, schedule routine maintenance for the entire hydraulic system to keep it running smoothly. 4. Regularly filter the hydraulic oil used in the high-speed press to avoid contamination and impurities. Impure oil can disrupt the normal operation of the hydraulic system, leading to premature wear of hydraulic components and even causing system failures. 5. Periodically clean the oil tank and hydraulic components, tighten pipe fittings, remove contaminants through filtration, and replace worn parts as needed to maintain optimal system performance. 6. Conduct regular tests on the hydraulic system and establish a dedicated testing area to ensure thorough evaluation of its functionality. 7. Prevent vibrations in the hydraulic system, as they can loosen pipe connections, leading to leaks—or worse, cause screws to break, posing a serious safety risk. Always take precautions to avoid any vibration in the system.

Considerations for Selecting Seals in Hydraulic Systems of Hydraulic Stations

2020-06-07

Hydraulic seals primarily include O-rings, as well as circular and square seals. These shapes give them advantages such as simple construction, ease of manufacturing, and low cost, making them widely used dynamic and static sealing elements in hydraulic systems at hydraulic stations. It is precisely these structural features that define their exceptional performance characteristics: 1. They effectively prevent leakage of internal fluids, ensuring excellent sealing even under harsh operating conditions like high pressure and extreme temperatures—without any significant increase in leakage rates. 2. They exhibit outstanding compatibility with hydraulic fluids. Since hydraulic seals are often immersed in oil for extended periods, they must resist swelling, dissolution, or embrittlement that could compromise their sealing integrity. Instead, they maintain their functionality and durability over time. 3. They offer the advantage of low friction. To minimize or eliminate undesirable phenomena like "creep" in hydraulic systems, these seals need to provide minimal static and dynamic frictional resistance, while also maintaining a highly stable coefficient of friction throughout operation.

Common Faults and Solutions for Hydraulic Stations in Plate Shears

2020-06-07

1. The oil circuit fails to build pressure, and the upper tool holder remains stationary. This is likely due to poor electrical contact at the solenoid directional control valve’s connector. Inspect the electrical plug, as the spool of the solenoid valve may be stuck by debris or worn out, preventing proper operation. Additionally, check if debris has accumulated in the sealing areas of the individual valve spools within the combination valve, disrupting their ability to seal effectively. Also, verify that any throttling holes inside the combination valve aren’t blocked—clean and disassemble these components as needed. 2. If the upper tool holder returns slowly or fails to reach the top dead center, it could indicate a misalignment in the sequence of movements between the tool holder and the material-pressing cylinder. Another possible cause is insufficient nitrogen pressure in the return cylinder. In each case, inspect the system carefully and adjust the pressure to the specified level. 3. To adjust the blade gap: First, temporarily loosen the locking screw, then turn the handle until you reach the desired setting. Once the correct position is achieved, securely tighten the screw again. A ball valve is used here to measure the uniformity of the gap between the upper and lower blades. The procedure involves performing a single stroke—when the tool holder reaches the bottom dead center, quickly turn the ball valve to shut off the oil supply, stopping the upper tool holder at that point. Afterward, slightly open and close the ball valve again, allowing the upper tool holder to rise incrementally throughout its full stroke. At this stage, you can measure the uniformity of the blade gap segment by segment. 4. If the return cylinder pressure is low, causing the upper blade to rise slowly, inflate the cylinder. Begin by removing the protective cap and the air valve cap from the return cylinder. Attach the inflation tool to the cylinder, ensuring the other end connects to a nitrogen tank (never use oxygen). Open the inflation tool and gradually activate the nitrogen tank’s shut-off valve, keeping a close eye on the inflation pressure gauge.

Operating Procedures for the Cone Crusher Hydraulic Station

2020-06-07

I. Operation of the Hydraulic Clamping System 1. Connect the hydraulic unit to the power supply and start the hydraulic oil pump. 2. Move the control handle of the clamping system to the locking position. At this point, the oil pressure indicated by the lock cylinder pressure gauge will steadily rise. When the pressure reaches 2500 PSI, the hydraulic unit’s oil pump will automatically stop. If oil leakage causes the pressure to drop below 2100 PSI, the pump will automatically restart. II. Operation of the Adjustment System 1. Stop the crusher. 2. Switch the control handle of the clamping system to the release position to drain the oil from the locking cylinder. 3. Once the oil pressure in the lock cylinder drops to "0," move the hydraulic unit’s clamping control handle to the neutral (middle) position. 4. Unlock the adjustment ring locking mechanism. 5. Start the hydraulic oil pump. 6. Operate the adjustment lever control handle to move it sequentially to the "extend" and "retract" positions. 7. Verify the size of the discharge opening by testing with lead blocks. 8. Reset the adjustment ring locking mechanism.

Analysis of the Current Status of Market Development in China's Bending Pipe Industry

2020-06-07

Currently, China's bent pipe market has already achieved a growth rate of 15% in recent years, placing it among the top three globally. This impressive pace of development bodes well, signaling substantial market potential and the thriving prospects of the entire industry. With the rapid expansion of China's national economy and infrastructure projects, coupled with adjustments in the country's industrial policies, the "replace steel with plastic" initiative introduced by the Ministry of Construction in 1998 has gradually gained traction across the nation. As a result, the market is increasingly embracing eco-friendly, innovative plastic bent pipes. Consequently, the energy-efficient and environmentally friendly pipeline sector holds immense untapped potential, brimming with limitless business opportunities. In recent years, hydraulic piping systems have seen remarkable advancements, giving rise to a wide array of cutting-edge products, including steady-state pipes, butt-welded pipes, aluminum-plastic composite pipes, steel-plastic composite pipes, and high-density polyethylene (HDPE) hollow-wall corrugated pipes. Notably, the growth rate of the eco-friendly bent pipe market is approximately four times faster than the average growth rate of the overall bent pipe market. In 2010, China rolled out a new policy called "Building Materials to Rural Areas," which has significantly boosted demand for plastic pipes in rural regions. In South China, urban utility networks and home improvement sectors are increasingly switching to plastic piping solutions, propelling the plastic bent pipe market into a peak marketing period. As a result, the supply of premium-grade plastic raw materials for bent pipes is expected to become highly scarce. The market potential remains vast. Statistics indicate that domestic demand for plastic bent pipes could continue growing at an annual rate exceeding 12%. This surge is particularly driven by China's accelerated pace of modern urbanization and its intensified efforts toward wastewater resource recovery. Applications in areas such as water and sewage systems, building heating systems, plumbing and drainage pipelines, gas and heating conduits, and large-diameter underground pipes are poised for significant expansion. By 2010, China's plastic pipe production had already reached 4.5 million tons, with projections indicating a further increase to 6 million tons by 2015—solidifying China's position as the world's largest producer of plastic pipes. Given this robust growth trajectory, bent pipe manufacturers must seize these opportunities by actively exploring new application areas and investing in brand upgrades to stay competitive. However, the current market landscape is characterized by intense brand competition and fragmentation. The construction materials sector boasts an overwhelming variety of products, leading to fierce rivalry across all price segments—from high-end to budget-friendly. Each market tier features several to dozens of competing brands, often battling not only against rivals within their own category but also against products from other tiers. For instance, in the PE pipe segment (used for high-density polyethylene water and gas distribution), prominent brands include Jinniu, Baoshuo, Liansu, Jinde, Gudi, and Baidie. Meanwhile, the PP-R pipe market is dominated by giants like Liansu, Jinniu, Jinde, Jiangtong, Jiangte, Aikang, Weixing Shuangdi, Shangpu, and Gudi. Beyond these established players, emerging products such as steady-state pipes, butt-welded aluminum-plastic composites, steel-plastic composites, and HDPE hollow-wall corrugated pipes face even fiercer competition. Unfortunately, the bent pipe market suffers from severe product homogeneity, compounded by consumers' lack of awareness about product features and specifications. This results in a significant information gap between buyers and sellers, often leading consumers to make purchasing decisions based solely on appearance and price rather than brand loyalty. As a consequence, many businesses struggle to effectively differentiate themselves, failing to build strong, recognizable brands that resonate with consumers. Instead, they end up caught in a cycle of misjudging market dynamics, neglecting brand-building efforts, and ultimately losing touch with consumer preferences. Moreover, brand awareness remains disappointingly low across the industry. Many bent pipe manufacturers exhibit weak brand consciousness, with underdeveloped marketing networks and limited investment in technological innovation or capital-intensive R&D. This leaves most companies operating on a relatively small scale, relying on simplistic marketing strategies and facing disproportionately high operational costs. Without clear brand positioning or targeted market research, many firms rush headlong into production without fully understanding their target audiences or niche markets. As competition intensifies, some companies find themselves trapped in challenging scenarios: escalating channel conflicts, rising production costs, declining revenues, and mounting customer complaints—all while experiencing a sharp drop in overall satisfaction levels. So, how can manufacturers carve out a sustainable competitive edge in this crowded marketplace? Beyond traditional channel-focused marketing strategies, companies must dedicate significant resources to crafting powerful, unified brands that are embraced by both distributors and end consumers. Only by fostering such strong, mutually recognized brands can businesses secure a solid foothold in the evolving market landscape—and ultimately pave the way for long-term success.
