II. Core Advantages: Five Integrated Transmission Strengths, Defining High-Risk Hygienic Industry Standards
1. Clean-Explosion-Proof Integrated Cabinet, Multi-Attitude Safe Hygienic Installation
The series adopts a clean-explosion-proof integrated cabinet structure optimized by finite element analysis, and the cabinet is made of 316L stainless steel with seamless welding technology and electrolytic polishing (surface roughness ≤Ra 0.4μm), which avoids dead corners where dirt and bacteria accumulate and is easy to clean and disinfect, meeting the strict clean requirements of high-risk hygienic industries. At the same time, the cabinet adopts flameproof gap design (gap ≤0.15mm) and reinforced explosion-proof structure, which can effectively prevent flame leakage in case of internal ignition. The six core models cover diversified input-output attitudes to meet extreme high-risk hygienic environment equipment layout needs: WPEDA (standard clean-explosion-proof type), WPEDS (clean-explosion-proof type with input shaft upward), WPEDO (clean-explosion-proof type with output shaft upward), WPEDX (clean-explosion-proof type with output shaft downward), WPEDKA (clean-explosion-proof type with input shaft downward), WPEDKS (clean-explosion-proof type with vertical input shaft). The cabinet is equipped with stainless steel clean-explosion-proof mounting flanges and precision positioning holes on multiple sides, which can flexibly switch between horizontal, vertical, wall-mounted, ceiling-mounted and other installation modes. The installation positioning accuracy error is ≤0.1mm, and the mounting base is designed with anti-vibration, anti-static and heat insulation gaskets made of food-grade fluorine rubber, which effectively ensures the stable, safe and hygienic operation of the transmission system under frequent start-stop, vibration and high-temperature conditions.
2. Enhanced Wear-Resistant Corrosion-Resistant Transmission, High-Reliability & Stable Operation
The series adopts enhanced clean-explosion-proof worm gear transmission pair design, the worm is made of 2Cr13 stainless steel, processed by integral forging, carburizing and quenching, and super-precision grinding, with surface hardness up to HRC 60-64 and tooth surface roughness ≤Ra 0.3μm. The worm gear is made of high-wear-resistant, corrosion-resistant and food-compatible nickel-aluminum bronze (ZCuNi10Al1) with precision tooth profile modification, and the meshing contact area reaches more than 95%, realizing uniform force transmission and high-precision operation. The worm shaft adopts large-diameter integral rigid design, and the bearing adopts high-load self-aligning roller bearings with double-sided sealing and dust-proof cover, which improves the shaft system bearing capacity by 50% compared with ordinary clean models. The transmission accuracy error is ≤0.15arcmin, and the transmission system can bear 3.0 times the rated torque impact, which can perfectly match the heavy-load impact working conditions of high-risk hygienic industries such as explosive pharmaceutical synthesis. The no-load operating noise is ≤55dB, and the load operating noise is ≤62dB (measured at 1m distance), ensuring relatively quiet operation under heavy load and avoiding static electricity generation caused by excessive vibration.
3. Integrated Clean-Explosion-Proof Matching, Wide-Range Power Adaptation

The flange and cabinet are integrally cast with coaxiality error ≤0.03mm, avoiding transmission efficiency loss caused by assembly errors. The explosion-proof junction box is integrated on the cabinet with a sealed design, which can directly connect the motor's explosion-proof circuit, simplifying the wiring process and avoiding potential safety and pollution hazards caused by external wiring. This integrated clean-explosion-proof matching design not only improves the product's versatility and safety in high-risk hygienic environments, but also reduces the user's equipment procurement cost and debugging cycle.
4. Multi-Layer Intelligent Sealing & Efficient Heat Dissipation, Harsh High-Risk Environment Adaptation
The sealing system adopts enhanced five-layer intelligent protection design: outer layer stainless steel explosion-proof labyrinth seal + middle layer food-grade fluorine rubber double-lip oil seal + inner layer O-ring + bottom layer anti-dust, anti-water and anti-corrosion cover + intelligent oil leakage monitoring sensor, with high-temperature resistant, corrosion-resistant and flame-retardant food-grade sealant at the cabinet joint, achieving IP67 protection level. It can effectively prevent the intrusion of flammable gases, toxic and corrosive media, cleaning agents, dust and other impurities in high-risk hygienic environments, and the intelligent sensor can timely alarm when oil leakage occurs, avoiding safety accidents and product pollution caused by lubrication failure. The cabinet is designed with integral spiral heat dissipation fins, and the heat dissipation area is increased by 40% compared with ordinary models. It adopts optimized forced circulation lubrication with oil cooler, and the built-in high-precision oil filter and oil temperature sensor ensure the cleanliness and temperature stability of lubricating oil. Using FDA-certified special heavy-duty explosion-proof synthetic worm gear oil, the product can work normally in the operating temperature range of -35℃ to +125℃, adapting to extreme temperature difference and high-risk media environments such as low-temperature pharmaceutical synthesis and high-temperature cosmetic raw material processing.
5. Intelligent Status Monitoring & Easy Maintenance, Cost-Saving Safe Hygienic Operation
The product is equipped with an intelligent status monitoring system, which can real-time monitor key parameters such as oil temperature, oil level, vibration amplitude and seal integrity through built-in sensors. The monitoring data can be transmitted to the remote control center through the RS485 communication interface, realizing remote fault early warning and status diagnosis, which is convenient for users to carry out predictive maintenance. The key components of the product adopt high-wear-resistant, high-temperature resistant, corrosion-resistant and food-grade materials, and the worm gear and worm undergo special anti-corrosion, anti-static and anti-pollution surface treatment to improve their adaptability to high-risk hygienic environments. The rated service life reaches more than 15 years under normal maintenance conditions, and the maintenance cycle is extended by 60% compared with ordinary models. The centralized clean-explosion-proof oil filling port, large-diameter oil drain port and transparent explosion-proof oil level observation window facilitate daily lubrication management and maintenance operations without disassembling the explosion-proof structure.
