In frigid regions, traditional gear pumps often fail to operate due to extremely low temperatures. However, LCB high-viscosity gear pumps are emerging as the core solution for efficient fluid conveyance in such environments. Their key advantage lies in effectively addressing three major challenges posed by low temperature fluid solidification, equipment embrittlement, and difficult startup through thermal insulation design, low-speed operation, and positive displacement mechanisms.
In general, material fracture is the most common issue encountered by traditional gear pumps in low-temperature environments. The LCB series gear pumps utilize specially treated low-temperature alloy steel, ensuring that critical components such as the pump body and gear shaft maintain excellent impact toughness even under extreme conditions of -50°C. This material selection not only guarantees efficient pumping performance at low temperatures but also minimizes seasonal-related downtime and production interruptions. The pump cover integrates a bypass valve, allowing pre-circulation heating before startup, which engages the main line only after the medium viscosity decreases. This approach prevents motor overload while enabling precise flow adjustment during operation, meeting the demands of frequent start-stops and load fluctuations in high-altitude cold regions.
To prevent seal hardening and contraction in frigid environments, which could lead to medium leakage or air ingress causing malfunctions, this equipment employs an adaptive low-temperature sealing system crafted from specialized elastic materials. Thus, seals maintain elasticity and maintain a tight seal against moving components in most extreme conditions, preventing medium leakage. The pump housing incorporates a hollow jacket with inlet oroutlet flanges, enabling continuous heating of the pump chamber via thermal oil, steam, or hot water. This maintains the flowability of temperature-sensitive media like asphalt and heavy oil at -40°C or lower temperatures, directly preventing blockages caused by solidification at the source.
In high-altitude cold regions, the immense stress generated by soil freezing and expansion can adversely affect underground pipelines and equipment. Therefore, the LCB biutmen gear pump employs a unique flange design and elastic support system to accommodate minor foundation displacement without compromising operational precision. Simultaneously, it enables gradual preheating of critical components before startup to prevent stress concentration caused by sudden temperature changes, while fluid-dynamically optimized flow path design significantly reduces startup resistance, addressing the challenge of difficult startup in frigid environments. LCB heat preseveration gear pump, featuring fracture-resistant materials and low-temperature sealing technology, not only enhances pumping efficiency under extreme cold conditions but also significantly reduces production and maintenance costs. It stands as a systemic solution engineered to overcome challenges in harsh environments.
