1. Hot Water Air Bubble Pressure Leak Inspection Principle
TPT1600 hydraulic pressure tester adopts mature hot water bubble detection to inspect cooling circuit tightness of cylinder heads and blocks. Seal all cooling circuit outlets with matched rubber stoppers, inject compressed air, then submerge workpieces in heated water bath. Visible air bubbles instantly expose hidden cracks, fissures and micro leakage points for intuitive, clear defect judgment.
2. Hot-State Simulation Uncovers Cold Inspection Blind Spots
Built with dual 5.5kW heating modules and 0–92°C adjustable thermostat to replicate real high-temperature engine running conditions. Hot-water bath testing reveals tiny thermal-induced cracks invisible under cold room-temperature inspection, effectively eliminating undetected leakage risks and preventing post-overhaul engine oil/water mixing and power loss.
3. Continuous Industrial-Grade Structure with Low Maintenance
Specially engineered for long uninterrupted daily batch detection work. The ergonomic simplified control layout lowers operation learning barriers, requiring no professional training for new technicians. It features minimal maintenance requirements to cut workshop upkeep costs, equipped with full built-in safety protection components to avoid pressure overload hazards during long shifts.
4. Heavy-Duty Stable Frame & Universal Wide Compatibility
Constructed with anti-corrosion stainless steel water tank and 650kg rigid anti-vibration heavy frame, driven by independent 0.37kW gear motor and 0.75kW circulation pump under 380V industrial power. Large loading capacity fits cylinder heads of passenger cars, trucks, tractors and industrial diesel engines, ideal diagnostic equipment for engine remanufacturing plants and fleet overhaul centers.

FAQ
Why is hot water pressure testing important for cylinder head inspection?
Hot water pressure testing allows workshops to detect cracks and leaks that may only appear when the cylinder head expands under operating temperatures. Compared with visual inspection alone, the TPT1600 provides a more reliable method for identifying hidden coolant passage defects before machining and rebuilding.
What problems can the TPT1600 detect in engine cylinder heads?
The TPT1600 is designed to detect internal cracks, coolant leaks, and sealing problems in cylinder head cooling circuits. It helps engine rebuilding workshops identify defective cylinder heads before processes such as surface grinding, valve seat machining, and final assembly.
How does the TPT1600 improve cylinder head rebuilding efficiency?
The TPT1600 uses a quick clamping system, hydraulic lifting cradle, and 360° electric rotation fixture to simplify loading and inspection. These features help technicians test cylinder heads faster, reduce manual handling, and improve workflow efficiency in professional engine repair shops.
Is the TPT1600 suitable for diesel and commercial engine cylinder heads?
Yes. The TPT1600 is suitable for testing cylinder heads from automotive engines, diesel engines, commercial vehicles, and industrial engines. Its large working capacity allows professional workshops to inspect various cylinder head sizes before repair or remanufacturing.
Why should engine rebuilders test cylinder heads before machining?
Testing before machining helps avoid investing time and labor into damaged cylinder heads. By identifying hidden cracks or leakage problems early, workshops can reduce failed repairs, warranty issues, and unnecessary machining costs while improving rebuilt engine reliability.
If the machine breaks down, how do you provide after-sales support? Do you provide operation videos?
Yes. We provide comprehensive after-sales support, including remote technical assistance, online troubleshooting, operation manuals, demonstration videos, maintenance tutorials, and live video guidance. If replacement parts are required, genuine spare parts can be supplied quickly to minimize downtime and keep your machine running efficiently.
Can you issue Certificates of Origin (CO), Form A, Form E, or other export documents?
Yes. We can provide the necessary export documents—including Certificates of Origin (CO) and other preferential certificates such as Form E—in accordance with the trade agreements and customs requirements of the destination country. We can also assist you in preparing commercial invoices, packing lists, bills of lading, and other export documentation.
What is your minimum order quantity (MOQ)? Do you support OEM & ODM customization?
Our standard MOQ is 1 machine for most models. We also provide OEM and ODM services for distributors and equipment brands, including custom logos, machine colors, nameplates, voltage, packaging, and other specifications to meet your market requirements.
Which shipping ports do you use? Can you deliver to my designated warehouse?
We typically ship from major Chinese ports, including Shenzhen, Guangzhou, Ningbo, and Shanghai. We can also arrange delivery to your designated warehouse, freight forwarder, or project site through flexible international shipping solutions.
How long does delivery take to my country?
Production typically takes 7–35 days, depending on the machine model and order quantity. Shipping time varies by destination and transportation method. Once your order is confirmed, we will provide a detailed production schedule and estimated delivery time.
