The Urea pump box integrated system is a meticulously engineered emissions control solution designed specifically for the HOWO Max 4X2 tractor. This advanced assembly integrates twelve critical components that work in harmony to ensure precise urea dosing, optimal SCR performance, and sustained compliance with China V emission standards. As a cornerstone of modern diesel exhaust aftertreatment, the Urea pump box integrated system delivers reliable operation under the most demanding heavy-duty conditions.
This comprehensive system comprises the following precision-engineered elements: Urea measurement valve of China V SCR system, Mix chamber pressure sensor, Accumulator pressure sensor, Urea solution pump, Back-blowing valve, Pressure-relief valve, Pressure stabilizing valve, Urea filter element, 3D filter mesh, Pump housing component (Non-heating), Urea liquid level/temperature sensor (Non-heating), and Wiring harness in pump (Non-heating). Every component within the Urea pump box integrated system is manufactured to exacting tolerances, ensuring seamless compatibility and long-term durability for fleet operators who demand uncompromising quality from their howo Parts.
The Urea pump box integrated system represents the pinnacle of SCR technology integration. By consolidating all critical fluid management and sensing functions into a single, robust enclosure, this system simplifies installation, reduces potential leak points, and enhances overall reliability. Whether you are maintaining an existing fleet or upgrading to meet stricter emissions regulations, the Urea pump box integrated system provides the performance and peace of mind that HOWO customers have come to expect.
The Urea measurement valve of China V SCR system is a precision flow-control device that regulates the exact quantity of urea solution injected into the exhaust stream. This valve operates with exceptional accuracy, responding to real-time engine data to maintain optimal NOx reduction efficiency.
Engineered specifically for China V emissions compliance, this valve ensures that the Urea pump box integrated system delivers the precise urea dosage required for complete conversion of nitrogen oxides into harmless nitrogen and water. Its robust construction resists crystallization and wear, even under extreme temperature fluctuations.
The Mix chamber pressure sensor continuously monitors the pressure within the urea mixing chamber, providing critical data to the engine control unit. This sensor enables the Urea pump box integrated system to maintain ideal mixing conditions for efficient NOx reduction.
With a wide operating range and rapid response time, this sensor detects even minute pressure variations that could affect SCR performance. Its durable design withstands the corrosive nature of urea vapor and the high-temperature environment typical of exhaust aftertreatment systems.
The Accumulator pressure sensor measures the hydraulic pressure within the system’s accumulator, ensuring that the Urea pump box integrated system maintains adequate pressure for instantaneous urea delivery. This sensor is vital for consistent spray atomization and complete exhaust gas mixing.
Built with high-grade piezoresistive technology, this sensor delivers accurate readings across a broad pressure spectrum. Its reliable performance helps prevent under-dosing or over-dosing scenarios, safeguarding both the SCR catalyst and the engine’s overall efficiency.
The Urea solution pump is the heart of the Urea pump box integrated system, delivering a steady flow of urea solution from the tank to the injection nozzle. This pump is designed for continuous duty, providing consistent pressure and flow regardless of engine load or ambient conditions.
Featuring advanced wear-resistant materials and a self-priming design, the urea solution pump ensures rapid system priming and dependable operation. Its compact footprint and low power consumption make it an ideal choice for space-constrained engine compartments in the HOWO Max 4X2.
The Back-blowing valve is an innovative feature of the Urea pump box integrated system that prevents urea crystallization and nozzle clogging. By periodically directing compressed air backward through the injection line, this valve clears residual urea droplets and keeps the system pristine.
This proactive cleaning mechanism significantly extends the service intervals of the entire SCR system. The back-blowing valve operates automatically based on predefined cycles, ensuring that the Urea pump box integrated system remains free from deposits that could impair performance.
The Pressure-relief valve serves as a critical safety device within the Urea pump box integrated system, protecting the system from overpressure events. Should the urea pressure exceed safe limits, this valve opens to release excess fluid, preventing damage to sensitive components.
Calibrated to precise pressure thresholds, the pressure-relief valve offers both passive and active protection. Its reliable operation ensures that the system maintains safe operating pressures at all times, contributing to the overall longevity of the SCR aftertreatment system.
The Pressure stabilizing valve works in tandem with the pump to maintain a constant urea pressure within the Urea pump box integrated system. This valve compensates for flow variations caused by engine speed changes, ensuring that the injection pressure remains steady and predictable.
With its precision-machined internal components, the pressure stabilizing valve delivers exceptional flow control with minimal hysteresis. This stability is essential for achieving the precise urea-to-exhaust ratio required for optimal NOx conversion efficiency under all operating conditions.
The Urea filter element is a vital maintenance component that removes particulate contaminants from the urea solution before it reaches the injection nozzle. This filter protects the entire Urea pump box integrated system from abrasive particles that could cause premature wear or clogging.
Constructed from high-efficiency filtration media, the urea filter element offers excellent dirt-holding capacity while maintaining low flow resistance. Regular replacement of this element is recommended to ensure the Urea pump box integrated system continues to deliver peak performance.
The 3D filter mesh is an advanced filtration layer that captures microscopic impurities and urea crystals before they can enter the pump or injector. This three-dimensional structure offers superior surface area for particle entrapment, enhancing the overall cleanliness of the Urea pump box integrated system.
Unlike conventional flat filters, the 3D filter mesh provides multidirectional filtration, ensuring that even the smallest contaminants are effectively removed. This mesh is particularly effective at trapping urea crystal seeds that could otherwise grow and cause blockages in the system.
The Pump housing component (Non-heating) provides a rugged protective enclosure for the internal mechanisms of the Urea pump box integrated system. This non-heating variant is designed for applications where ambient temperatures remain within the safe operating range, eliminating the need for integrated heating elements.
Crafted from corrosion-resistant materials, this housing shields the pump and sensors from environmental contaminants, moisture, and mechanical impacts. Its modular design facilitates easy access for inspection and maintenance, reducing downtime for fleet operators.
The Urea liquid level/temperature sensor (Non-heating) provides dual-function monitoring of both the urea solution level and its temperature within the tank. This sensor enables the Urea pump box integrated system to alert the driver when urea levels are low and to adjust injection parameters based on fluid temperature.
Featuring solid-state sensing elements, this sensor offers exceptional accuracy and long-term stability. The non-heating design is ideal for temperate climates where urea freezing is not a concern, providing a cost-effective solution without compromising on monitoring capabilities.
The Wiring harness in pump (Non-heating) is the nervous system of the Urea pump box integrated system, transmitting power and signals between the pump, sensors, and the vehicle’s electronic control unit. This harness is engineered to withstand the harsh under-hood environment, including vibration, heat, and chemical exposure.
Each wire in the harness is precisely terminated and color-coded for easy identification during installation and troubleshooting. The non-heating variant is optimized for standard operating conditions, offering reliable connectivity without the complexity of integrated heating circuits.
