1. Product Overview
This is an original SANY pressure cap specially designed for coolant expansion tanks. As a key safety component of the cooling system, it features a precision dual-valve structure with pressure relief and vacuum compensation functions. It seals the filler opening of the expansion tank and dynamically regulates system pressure to prevent coolant boiling at high temperatures, tank collapse and pipeline rupture. It ensures stable heat dissipation of the engine under harsh working conditions such as mining and heavy-load operation.
2. Material & Structure
Cap Body: Made of high-strength heat-resistant engineering plastic with galvanized steel inserts. It is anti-aging and resistant to corrosion by ethylene glycol coolant. It will not crack or deform under long-term high temperature (≤110℃) and features solid and durable construction.
Sealing Gasket: Made of fluoroelastomer (FKM), operating within -40℃ ~ 130℃. It maintains lasting elasticity and tight sealing to effectively prevent coolant leakage and evaporation.
Core Dual-Valve Assembly:
Pressure Relief Valve: Equipped with high-strength internal spring to accurately control opening pressure and release excess pressure automatically.
Vacuum Compensation Valve: Adopts one-way valve structure to intake air automatically and balance system pressure when negative pressure occurs with the engine off.
Dustproof Outer Cap: Designed with anti-slip patterns to block dust and sediment, keep internal valves clean and allow easy manual installation, removal and maintenance.
3. Main Technical Parameters
Rated Opening Pressure: 0.2MPa (2.0bar)
Vacuum Opening Pressure: -0.02MPa (-0.2bar)
Operating Temperature Range: -40℃ ~ 110℃
Matching Caliber: Standard 60mm (100% compatible with the port of Expansion Tank 8232365)
Pressure Resistance: No leakage under 0.3MPa pressure holding (100% full inspection before delivery)
Service Life: ≥5000 hours under mining and heavy-load conditions
Pressure Regulation & Anti-Boiling: Stabilize the system pressure at 0.2MPa during operation and raise the boiling point of coolant to 108℃. It avoids high-temperature cavitation and boiling, and keeps the engine running with steady power.
Vacuum Compensation & Anti-Collapse: Balance negative pressure automatically when the engine cools down to prevent tank collapse and pipeline deformation, protecting Expansion Tank 8232365.
Leak-Proof & Loss Reduction: The FKM gasket eliminates leakage and reduces coolant consumption, preventing high-temperature alarm and cylinder scuffing caused by insufficient liquid level.
Original Fit & No Modification: Genuine SANY part, fully compatible with SANY SY365H and Expansion Tank 8232365. It can be directly screwed on for easy installation and removal without extra adjustment.
Strict Quality Inspection & High Reliability: Manufactured in accordance with original factory standards. Every unit passes pressure, sealing and temperature resistance tests, suitable for harsh operating environments of construction machinery including heavy load, heavy dust and high temperature.
5. Common Faults & Impacts
Stuck Open Pressure Valve: Insufficient system pressure leads to easy coolant boiling, resulting in high water temperature, reduced power and increased fuel consumption.
Stuck Closed Pressure Valve: Excessively high system pressure may cause potential hazards such as tank bulging, pipe burst and joint leakage.
Failed Vacuum Valve: Negative pressure cannot be released after engine shutdown, causing tank collapse, deformation, cracking and abnormal coolant backflow.
Aged Sealing Gasket: Coolant leakage and dropping liquid level will trigger frequent alarms. In severe cases, it will lead to engine overheating and cylinder scuffing.
6. Application Scope
Model: SANY SY365H Mining Excavator (Isuzu 6HK1 Engine)
Matching Expansion Tank: 8232365 (SANY Material Code: 60310012)
Application Scenarios: Mining, heavy-duty construction, high-temperature operation and other working conditions
