The water pump for road rollers is available in two voltage specifications: 12V and 24V, and the water volume covers three standards: 1.8Qpm, 2.3Qpm, and 4.0Qpm. Its core function is to achieve heat dissipation protection for the engine and hydraulic system through the circulation of coolant and hydraulic oil. It also has the function of lubricating key components, which can effectively prevent equipment from overheating and damage and extend its service life. The water pump can maintain the optimal operating temperature of the engine and ensure the stable operation of the hydraulic system under high temperature and high load conditions. The types include mechanical and electronic types. High-end models use high-pressure design to ensure the stability of oil delivery. In road construction scenarios, the reliability of the water pump is directly related to equipment performance and construction efficiency, and regular maintenance is required to avoid the risk of failure.
