Stress generated inside the truck corrosive environments such as high temperatures generated by the engine and sulfur, chlorine ions and other combustion gas, generated mist battery, leakage, work of vibration, generated by the impact, friction, etc. caused by collision damage is caused by partial the main reason for corrosion damage YTO forklift Parts. In consideration of the overall layout of the truck to prevent the accumulation of corrosive media. Avoid enclosed area, or remain closed system ventilation and good drainage, such as consideration of internal combustion battery forklift ventilation, cooling. Exhaust emissions produced by the engine as much as possible or by purification, cooling from the upper discharge counterweight up from the lower counterweight. For battery forklift as reach trucks, you can open the windows are to keep the motor cooling and ventilation, battery leakage bottom opening hole and install the fluid filter. Used Forklift smooth shift key parts of the spring pressure accumulator and the main valve. How it works: piston accumulator piston mounted on the ends of the cylinder, the right (in the figure below) on top of the spring, the size of the spring at the right end of the top bosses were the main pressure valve and housing. Between the plug and left ends of the piston forming an oil chamber A, and through the oil passage communicating with the valve in the communication passage. During this trail equipped with check valves and oil orifice. When the oil flows into the hydraulic shift clutch shift cylinder, so that the oil in the lower oil pressure, oil chamber accumulator oil chamber A supplement oil through the check valve, the brake or clutch combination quickly. At the same time due to the oil outflow oil chamber A, in the main pressure control oil passage (ab) the role of the valve stem so that the left hydraulic system decreases, when the main, driven plate snapping, cylinder stops moving, oil rise part of the flow of oil through the orifice oil chamber a, a pressure oil chamber gradually increased, pushing the piston to the right, compression springs, the main pressure valve stem to the right, so that the hydraulic system will be gradually increased, so Lord, driven components combined with smooth, smooth and reliable shifting. Avoid crevice corrosion, galvanic corrosion, stress corrosion cracking. For the inevitable gaps Welded structures such as the hood closed the gap with sealant. Connecting dissimilar metals should try to select potential close to the metal, or to take measures to avoid electrochemical corrosion insulation.
