The press roller housing is one of the most vulnerable parts of the machine. Due to heavy loads, high temperatures are generated, which normal grease cannot withstand. Special greases may not work effectively or can be too expensive. This makes it a critical area for maintenance and monitoring.
The system includes a recycling cooling water mechanism that cools the bearing box, working chamber, and both left and right press roller housings. The ideal oil temperature is between 40–60°C. If it exceeds 80°C, the oil film breaks down, leading to loss of lubrication and potential damage.
Temperature sensors are installed in key areas, including the main motor (3 units), gearbox (1 unit), working chamber (1 unit), middle bracket (1 unit), and press roller housings (4 units). This real-time monitoring helps prevent overheating and ensures smooth operation.
Unlike traditional machines, which require adjusting the press roller gap before starting, our machine allows for gap adjustment while running. This feature offers convenience, speed, and precision. Both gaps can be adjusted simultaneously and in sync, improving efficiency and product quality.
The role of the valve is specifically responsible for the input of air into the engine and exhaust the exhaust gas after combustion. From the engine structure, it is divided into Intake Valve and Exhaust Valve.
The role of the intake valve is to draw air into the engine and mix it with the fuel to burn; The function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat.
The valve is composed of a valve head and a rod. The valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also withstand the pressure of the gas, the valve spring force and the transmission component inertia force, its lubrication, cooling conditions are poor, requiring the valve must have a certain strength, stiffness, heat and wear resistance.
The intake valve is generally made of alloy steel (chromium steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel).
Sometimes in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy, and the rod is made of chromium steel, and then the two are welded together.
