By no means alarmist! The danger of high oil temperature in the manual hydraulic truck is very great!

by:Staxx Pallet Truck     2022-05-24
Manual hydraulic pallet truck is a manual lifting tool, which is very convenient to use, commonly known as 'earth cow'. When the manual hydraulic truck is used for a long time, the oil temperature will be too high. If the oil temperature is too high, it will cause a lot of harm.


First, the hydraulic oil temperature of the manual hydraulic pallet truck is high, the viscosity of the hydraulic oil will decrease, and the volumetric efficiency and working efficiency of the hydraulic system of the hydraulic pallet truck will decrease. Vehicle leakage will rise, and even make manual hydraulic trucks unable to work properly.
2. The hydraulic components of the manual hydraulic pallet truck expand due to thermal expansion and cold contraction, which will make the sliding pair clearance of the hydraulic components of the manual hydraulic pallet truck smaller, resulting in an increase in the frictional resistance of the manual hydraulic pallet truck and easy hydraulic valves. At the same time, the formed hydraulic oil film becomes thinner and the wear of the manual hydraulic pallet truck increases, which is easy to cause the pump hydraulic pressure, hydraulic valve and other mating surfaces of the manual hydraulic pallet truck to fail or be scrapped due to wear.
Third, the rubber seals of the manual hydraulic pallet truck are easy to age, the service life of the manual hydraulic pallet truck is shortened, the rubber seals cannot achieve the sealing effect, and the hydraulic system of the manual hydraulic pallet truck leaks seriously.


Fourth, the evaporation of water and the vaporization of oil will easily cause cavitation on the mating surface; the oxidation of oil will form particle deposits, which will block the filter of the manual hydraulic pallet truck and the hydraulic system in the hydraulic system. Many orifices even make the hydraulic system of the manual hydraulic truck unable to work.
Excessive hydraulic oil temperature will affect the components of the entire hydraulic system of the manual hydraulic pallet truck, shorten the life of the manual hydraulic pallet truck, or even fail to work, making the entire manual hydraulic pallet truck in a state of paralysis.
