What are the hazards of excessive hydraulic oil temperature in manual forklift?

Manual forklift, also known as the cow and hydraulic pallet jack, is a simple lifting tool. Hydraulic oil of the manual forklift is too high and the damage is extremely high.

Manual forklift the main hazards are as follows:

The hydraulic oil temperature of the hydraulic pallet jack is high, the viscosity of the hydraulic oil of the hydraulic pallet jack will be reduced, the volumetric efficiency of the hydraulic system of the manual forklift and the working efficiency of the hydraulic system will decrease, and the leakage of the hydraulic pallet jack will increase, even making manual forklift is not working properly.

The hydraulic components of the manual forklift vehicle expand due to thermal expansion and contraction, so that the sliding gap of the hydraulic components of the hydraulic pallet jack vehicle becomes smaller, resulting in an increase in frictional resistance, a hydraulic valve of the manual forklift vehicle being easily stuck, and a hydraulic oil film formed. Thin, mechanical wear increases, resulting in failure of the mating surfaces of pumps, valves, motors, etc. due to wear and tear.

The rubber seal of the hydraulic pallet jack is easily deteriorated, the service life is shortened, and the sealing effect is not obtained, so that the hydraulic system of the manual forklift is seriously leaked.

The water vaporization of the hydraulic pallet jack and the vaporization of the oil easily cause cavitation on the mating surface, and the oil is oxidized to form particulate deposits, which may block the filter of the manual forklift, many orifices in the hydraulic system of the hydraulic pallet jack, and even the hydraulic system of the manual forklift is not working.

Therefore, the hydraulic oil temperature of the hydraulic pallet jack is too high, which will affect the components of the entire hydraulic system, shortening its life, or even working, making the entire manual forklift in a paralyzed state.
