How does the internal combustion forklift set its leak-proof measures

How does the internal combustion forklift set its leak-proof measures

  • 2022-08-30
We all know that in the process of using forklifts, there will be more or less problems, such as driving problems or other faults. For example, we are going to introduce the forklift leak prevention measures today. So how should we set the leak-proof measures for internal combustion hifoune diesel forklift for sale ? Below, our hifoune forklift manufacturer will introduce the leak-proof measures for internal combustion forklifts.
(1) Carefully handle various gaskets. For example, due to the large contact area of the oil pan or valve cover, it is difficult to press down, which is easy to cause oil leakage. Oil leakage from the rear oil seal of the crankshaft will penetrate into the clutch, which will not only consume oil, but also cause the clutch disc to become dirty and burn out.
(2) Tighten the nut according to the maintenance specification. If the gasket is too loose, it will leak oil; if it is too tight, it will cause the metal bulge around the screw hole, or the thread to slip, causing oil leakage. If the oil drain plug of the oil pan (casing) is not tightened or loosened and falls off, it is easy to cause a large amount of oil loss, and then the accident of "burning bushing and holding the shaft" occurs.
(3) Replace the faulty oil seal in time. Improper installation of the oil seal, misalignment between the journal and the edge of the oil seal, and easy deflection of oil; after long-term use, some will lose elasticity due to rubber aging, the sealing lip will be damaged and cracked, or the self-tightening spring will fail, and the oil seal function will be lost. Qualified accessories should be repaired or replaced as standard.
(4) Replace seriously worn parts in time. For example, if the cylinder liner, piston and piston rings are worn to a certain extent, the high pressure gases in the combustion chamber can be blown into the crankcase.
(5) Repair the main bearing in time. When the fitting clearance between the main bearing and the journal is too large, the front and rear oil seals will lose their sealing due to the impact of the crankshaft, causing the oil to leak from the crankshaft head or into the clutch, thereby contaminating the friction plates, resulting in slippage and work failures.
(6) Avoid blocking the check valve and exhaust valve. After the valve hole is blocked, it is easy to cause the temperature and pressure in the casing to rise, the resistance of the piston movement and the oil consumption to increase, the oil and gas to fill the entire space, the consumption of lubricating oil to increase, and the replacement cycle to be shortened. Due to the pressure difference between the inside and outside of the casing, oil leakage often occurs at the weak seal. Check, unblock and clean regularly to keep check valve and exhaust valve clear.
(7) Properly solve the sealing of various oil pipe joints. The pipe connection nut is often disassembled and assembled, which is easy to loosen due to thread breakage, which deteriorates the accuracy of the two joint bell mouths, poor contact due to misalignment of the taper lines, and mismatches due to different tapers, resulting in oil leakage. After grinding the pipe joint and sealing the bell mouth or clamping the thin copper coin on the two conical surfaces, tighten the compression nut to ensure the sealing.
(8) Avoid wheel hub oil throwing. When there is too much grease in the hub bearing and cavity, or improper assembly, poor quality, aging failure, frequent braking, etc., the hub temperature is too high, and the axle nut is loose, which will cause the hub to throw oil. Cavity lubrication (proper lubrication) should be used, ventilation holes should be cleared, brakes should be used reasonably, accessories should be strictly selected, and assembly and adjustment should be carried out according to process specifications.
