Description

LQRY High-temperature Thermal Oil Circulation Pump Product Details
1. Product Overview
The LQRY high-temperature thermal oil pump is a professional air-cooled energy-saving centrifugal pump customized for industrial high-temperature heat carrier circulation systems. Manufactured strictly in accordance with EN733 (DIN24255) European industrial standards, it abandons the traditional water cooling structure and realizes long-term stable operation up to 350℃ without additional cooling systems.
Adopting dual deep groove ball bearing support, front dual safety seal and rear pull-out modular structure, it features high temperature resistance, zero leakage, easy maintenance and high efficiency. It is specially designed for conveying particle-free and weakly corrosive high-temperature media, widely used in industrial heating, heat exchange and constant temperature circulation systems, serving as an ideal upgraded replacement for traditional water-cooled thermal oil pumps.
2. Core Product Advantages
1. European Standard Design with Strong Industrial Compatibility
Fabricated following EN733 (DIN24255) international industrial standards, the pump achieves high precision structural rigidity and assembly accuracy. It features strong compatibility and part interchangeability, perfectly matching imported and domestic complete heat exchange units and constant-temperature production lines, meeting standardized industrial supporting requirements.
2. Integrated Air-cooled Heat Dissipation, No Auxiliary Cooling Required
Equipped with an original optimized air duct structure on the bearing seat, it actively dissipates heat from the dynamic seal surface and bearings, effectively controlling core component temperature. It completely eliminates the need for cooling water pipelines and auxiliary water circulation equipment, simplifying system layout, saving engineering costs and occupying less installation space.
3. Dual Safety Seal & Throttling Protection, Zero High-temperature Leakage Risk
A safety packing seal and throttling buffer zone are installed in front of the dynamic seal. The throttling zone stabilizes pressure during normal operation; if the main seal fails accidentally, the front safety structure can quickly block the outward leakage of high-temperature medium, avoiding high-temperature medium ejection and scalding hazards, greatly improving the safety level of high-temperature operation.
4. Dual-bearing Symmetrical Support, Ultra-stable Hot Operation
The dual-end deep groove ball bearing structure ensures uniform stress and high coaxiality accuracy, effectively offsetting thermal deformation and fluid impact load under high-temperature conditions. It operates stably without jitter, deviation and abnormal wear at 350℃, supporting 24-hour uninterrupted industrial thermal circulation and solving the common defects of traditional pumps such as high-temperature jamming and short service life.
5. Rear Pull-out Structure, Pipeline-non-dismantling Maintenance
The advanced rear pull-out modular design allows direct extraction of core components such as rotors, bearings and seals for maintenance without disassembling pipelines or moving the whole pump. It greatly shortens downtime, reduces pipeline disassembly loss and maintenance costs, and adapts to continuous industrial production conditions.
6. Long-term High-temperature Energy-saving & Low-loss Operation
The optimized hydraulic model ensures stable flow rate, uniform pressure and high conveying efficiency. It operates without medium leakage and thermal loss in hot state, maintaining constant temperature and pressure of the thermal circulation system. The performance remains stable after long-term high-temperature operation, with outstanding energy-saving effect and durability.
3. Working Principle
The LQRY thermal oil pump operates on centrifugal conveying principle. The motor drives the high-precision impeller to rotate at high speed, forming stable negative pressure in the pump cavity to continuously suck high-temperature heat-conducting medium. The medium is pressurized and stabilized through the impeller and volute to realize closed-loop circulating heat exchange of the entire industrial system.
During operation, the integrated air-cooled structure realizes autonomous heat dissipation, the front throttling and sealing structure prevents medium leakage, and the dual-bearing system balances operating loads. The whole machine realizes long-term safe, efficient and cooling-free high-temperature medium circulation operation with stable performance.
4. Application Scenarios
Focusing on 350℃ high-temperature weakly corrosive medium closed-loop circulation, the LQRY thermal oil pump is dedicated to industrial high-temperature heating and constant-temperature heat exchange systems.
Petrochemical Industry: High-temperature heat conduction circulation and constant-pressure conveying for petroleum refining, chemical reaction kettles and heat exchange units.
Rubber & Plastic Industry: Constant-temperature thermal circulation for plastic injection molding, rubber vulcanization, synthetic fiber textile and printing & dyeing shaping equipment to stabilize production process temperature.
Food & Pharmaceutical Industry: High-temperature heat source circulation for food drying, pharmaceutical extraction and light industrial molding equipment, adapting to clean and weakly corrosive high-temperature working conditions.
Infrastructure & HVAC Industry: High-temperature heat medium conveying and circulating pressure stabilization for boiler supporting heat exchange, road maintenance heating and thermal insulation material production.
General Industrial High-temperature System: Closed-loop thermal oil circulation for industrial heating furnaces, drying equipment and mold temperature machines, suitable for particle-free and weakly corrosive high-temperature liquid transportation within 350℃.
5. Product Summary
With the core strengths of European standard precision manufacturing, independent air cooling without auxiliary cooling, dual safety anti-leakage protection, dual-bearing ultra-stable operation, pull-out maintenance design and long-term high-temperature energy saving, the LQRY high-temperature thermal oil pump solves the pain points of cumbersome water cooling, easy high-temperature leakage, difficult maintenance and unstable hot operation of traditional pumps. Professionally tailored for industrial high-temperature thermal oil closed-loop circulation systems, it features high safety, high efficiency and low maintenance cost, being the ideal upgraded special circulation equipment for various high-temperature thermal systems.
