The risk of excessive oil temperature in pallet jack is very high!

The outdoor pallet jack is a manual lifting tool that is very convenient to use and is often referred to as a “land cow”. If the pallet jack is used for a long time, the oil temperature is too high, which may cause some harm.

1, outdoor pallet jack hydraulic oil temperature is high, hydraulic oil viscosity is reduced, pallet jack hydraulic system volume efficiency and work efficiency will be reduced, outdoor pallet jack hydraulic oil leakage will increase, even pallet jack can not work properly .

2. The hydraulic components of the outdoor pallet jack expand due to thermal expansion and contraction, which makes the sliding clearance of the hydraulic components of the pallet jack smaller, resulting in increased frictional resistance of the outdoor pallet jack, easy to block the hydraulic valve, and at the same time, the formed hydraulic oil film Increased wear on thinner and pallet jack may result in ineffective or obsolete pump hydraulics and hydraulic valves for outdoor pallet jack due to wear.

3, the pallet jack rubber seal is easy to aging, the outdoor pallet jack has a short service life, the rubber seal has no sealing effect, resulting in serious leakage of the hydraulic system of the pallet jack.

4. Water evaporation, oil vaporization, it is easy to generate cavitation on the mating surface; oxidized oil forming particles will block the outdoor pallet jack filter, many holes in the hydraulic system, and even the hydraulic system of the pallet jack can not work .

Excessive temperature of the hydraulic oil will affect the components of the entire hydraulic system of the outdoor pallet jack, making the life of the pallet jack shorter or even inoperable, leaving the entire outdoor pallet jack in a paralyzed state.
