Core Specifications
Genuine Quality Assurance
As an authentic Weichai Power accessory, this product strictly complies with the technical specifications of the engine's original technical white paper. From the casting of the cast iron cylinder block to the assembly of precision components, it has passed Weichai's three-level quality inspection system verification. The cylinder block is made of high-strength gray cast iron HT250 material, which undergoes aging treatment to eliminate internal stress. Combined with imported fluororubber materials for piston rings and seals, it exhibits excellent high-temperature resistance (adapting to 90-110℃ working conditions in the engine compartment) and oil resistance. It can withstand long-term working pressure of 0.8-1.0MPa without leakage risks, avoiding cylinder block cracking and displacement attenuation problems caused by insufficient material strength of aftermarket parts.
Every air compressor undergoes full-process performance verification: from cylinder block air tightness test (pressure drop ≤0.02MPa after 12-hour pressure retention) to full-load operation test (simulating 1000 hours of continuous work), ensuring precise compatibility with Weichai Deutz 226B engines, WP6 series heavy-duty truck powertrains, and commercial vehicles of brands such as Sinotruk and Shacman. After installation, it can be directly integrated into the vehicle's braking system and pneumatic control circuit, providing stable compressed air for key functions such as brake boosting and door opening/closing. Meanwhile, it is backed by the warranty service of Weichai's global network of over 2,000 authorized service stations, with a 24-hour after-sales response mechanism to minimize equipment downtime losses.
Application Scenarios
Widely suitable for commercial vehicles, construction machinery, and fixed power equipment:
Commercial Vehicle Field: Air supply for the braking system of heavy trucks and tractors, compatible with brands such as Dongfeng, Hongyan, and Foton;
Its optimized unloading control logic can automatically start and stop according to the air tank pressure, reducing idle energy consumption by 15% compared with traditional models. It is suitable for harsh working conditions such as dust and humidity, with a service life of over 8,000 hours (1.5 times that of aftermarket parts).
Cost-Effectiveness Advantage
Genuine quality with significant domestic price advantage. Leveraging the large-scale production and supply chain integration capabilities of Weichai's Shandong Intelligent Manufacturing Base, while maintaining the same quality as original equipment parts, the procurement cost is reduced by more than 60% compared with imported similar accessories. The average price of overseas brand air compressors compatible with Weichai engines exceeds 2,000 RMB, while this product offers official quality assurance at a budget of less than 1,000 RMB. During the entire life cycle, due to fewer failures and low maintenance frequency, the total cost is saved by more than 50% compared with aftermarket parts.
