Check whether the arm-rubbish truck oil has white turbidity or serious pollution. If the oil appears turbid and white, it is likely that the engine coolant has been contaminated to repair or replace damaged parts. If the color of the oil becomes black, it will lose its visco-elasticity and impurity sensation by hand rubbing, which means that the engine oil will be used for a long time, and the high temperature and oxidation will cause the engine oil to form an oxidized polymer and gradually deteriorate. The moisture-containing engine oil is cloudy and has foam. Use your finger to dip the engine oil. If you see metal debris, it indicates that the engine is seriously worn and should be checked.
Check whether the organic waste is leaking around the following areas of the arm lift type garbage truck: oil sump (upper and lower); 2 oil sump drain plug; 3 oil pressure switch; 4 oil filter; 5 intake valve timing control electromagnetic Valve; 6 stop chamber front cover; 7 cylinder block and cylinder head mating surface; 8 cylinder block and rocker cover mating surface; 9 front and rear crankshaft seal; 10 oil filter (for intake valve timing control) When the engine oil pressure is not normal and the oil pressure warning light is on, check the oil pressure. The inspection method is as follows: Disconnect the oil pressure switch harness connector and use a deep casing to remove the oil pressure switch.
Screw the special tool into the free threaded hole. Set the engine tachometer with pull arm garbage truck. Start the engine and warm up to the normal operating temperature. Check engine oil pressure. At idle, the engine oil pressure should exceed 60 kPa; at speeds up to 2000 rpm, the oil pressure should exceed 260 kPa. Before reinstalling the oil pressure sensor, remember to wrap the sealing tape around the switch threads and tighten the switch at the specified torque. Start the engine and check if the oil pressure switch leaks. Shut off the engine, connect it to the pressure switch terminal and cover the oil pressure switch with a cover.
Chemical resistant Teflon Roll
The chemical resistant Teflon roll is highly resistant to most chemicals, including acids, bases, and organic solvents. It can withstand a wide range of temperatures from -200°C to 260°C, making it suitable for use in extreme environments. Additionally, it is non-reactive to most chemicals, making it an ideal choice for use in chemical processing applications.
The non-stick properties of Teflon make it an excellent choice for food processing applications. It is widely used in the production of cookware and baking sheets due to its ability to prevent food from sticking to the surface. The non-stick properties also make it easy to clean, reducing the need for harsh chemicals and abrasives.
The chemical resistant Teflon roll is also used in the production of semiconductors, where it is used to coat the inside of reaction chambers. The non-stick properties of Teflon prevent the buildup of unwanted deposits, ensuring that the reaction chamber remains clean and free from contamination.
In the pharmaceutical industry, chemical resistant Teflon roll is used to produce drug delivery systems. It is used to coat the inside of syringes and other medical devices, preventing the drugs from sticking to the surface and ensuring that the full dose is delivered to the patient.
