Product Description: Enclosed scraper ash conveyor with low friction, sturdy and durable, light-duty scraper conveyor. Working principle:When the spiral shaft rotates, due to the gravity of the material and the friction generated with the trough wall, the material can only move forward along the bottom of the conveyor's trough propelled by the blades. The situation is similar to a non-rotating nut moving translationally along a rotating screw. The movement of the material at the intermediate bearing relies on the thrust from the material advancing behind it. Therefore, the transportation of material in the conveyor is entirely a sliding motion. To keep the spiral shaft in a more favorable tension state, the driving device and discharge outlet are generally placed at the same end of the conveyor, while the feed inlet is placed as close as possible to the other end near the tail.The rotating spiral blades push the material for transportation. The force that prevents the material from rotating with the spiral conveyor blades is the material's own weight and the frictional resistance of the conveyor casing against the material. The blade surface types include solid surface, belt surface, and blade surface, depending on the material being conveyed. At the terminal end of the material movement direction, the spiral shaft of the conveyor has a thrust bearing to withstand the axial reaction force from the material. For longer conveyor lengths, intermediate hanging bearings should be added.Daily maintenance management: During the use of the spiral conveyor, it is essential to pay attention to daily maintenance to ensure optimal coordination with the sand dryer, guaranteeing production volume and efficiency, as well as extending the equipment's service life. (1) Regularly lubricate transmission parts such as bearings, gears, and chains. (2) After the conveyor is shut down, check the wear of the spiral blades and perform welding repairs if the wear is severe. (3) Do not overload the conveying capacity, as it may cause material blockage, bending of the spiral shaft, and damage to the casing. (4) When conveying high-temperature media, ensure that the casing expands and contracts freely without any obstruction; address any issues promptly. (5) If the conveyor emits harsh noise during operation, open the cover for inspection and troubleshoot the problem.Enclosed scraper ash conveyor with low friction, sturdy and durable, light-duty scraper conveyor. more>

Product Description: Laboratory Preparation: Cast Iron Test Base Ensures Experimental SafetyIn the operational system of testing machines, the sensitive readings of sensors, dynamic loading of the mainframe, and the calculations of the data system are often regarded as the "main characters," while the cast iron base remains in a "silent" state—it generates no data, makes no sound, yet supports the entire testing process with its substantial presence. This "silence" is not without value but embodies a profound "philosophy of support": it dampens vibrations with its material resilience, ensures truth through stability and precision, and endures time with its durability. It is both the "core foundation" in technical terms and a paradoxical unity of "ordinary and great," "dynamic and static," and "short-term efficiency and long-term value" in philosophical terms.Core Value: The "Three Pillars" Silently Supporting the Testing SystemThe value of the cast iron base lies hidden behind every test, underpinning the credibility of test data and the reliability of the testing system through its three core capabilities: "stability and durability," making it an indispensable "silent supporter."1. Vibration Resistance and Damping: Isolating Interference with "Silent Damping" to Safeguard Data TruthThe accuracy of test data fundamentally relies on "true measurements free from interference." When a fatigue testing machine loads at a frequency of 100Hz, the vibrations generated, if transmitted to the sensors, can cause stress-strain data drift, obscuring the "true results" with "interference noise." The graphite structure (flaky or nodular) within the cast iron base acts like countless tiny "dampers," with a damping ratio of 0.03-0.05, capable of absorbing over 80% of vibrations and keeping the vibration amplitude at the sensor end within 0.003mm. This "soft overcoming hard" damping ability makes the base a "guardian of data truth." It does not actively "correct" data but, by isolating interference, enables sensors to capture the material's genuine mechanical response—akin to the philosophical process of "removing obscurity to restore essence," silently safeguarding "truth."2. Precision Stability: Anchoring Reference Coordinates Through "Aging Precipitation" to Prevent DeformationThe precision benchmark of a testing machine serves as the "coordinate point" for all tests. Once this benchmark drifts, subsequent measurements become meaningless, like "measuring height on shifting ground." The cast iron base undergoes a "dual tempering" process before leaving the factory: high-temperature aging at 550°C and natural aging for six months. This slow stress release increases the residual stress removal rate to over 85% and controls annual precision decay within 0.002mm/m. This "aging precipitation" process mirrors the philosophical concept of "quantitative change leading to qualitative change": it does not seek short-term "rapid forming" but achieves material stability through time accumulation, ensuring that Grade 0 flatness precision remains within ≤0.05mm/m long-term. Compared to lightweight bases that are "quickly processed but frequently deform," the "precision stability" of cast iron bases embodies "long-termism"—exchanging silent "time costs" for long-term "precision value" in the testing system, becoming an unshakable "reference anchor."In an era focused on "tangible outcomes," we should pay more attention to these "silent foundations"—whether basic components in industrial systems or ordinary workers in societal development. They support the stable operation of the entire system with "unassuming responsibility." As the cast iron base teaches us: true value does not require loudness; sometimes, silent perseverance is the most powerful support.Ms. Xie from Qili Machinery: 13785751790 more>
