If the oil temperature is too high hydraulic grab how to do

Release date: 2016-08-02 Author: Click:

Hydraulic (grab) oil temperature is too high will directly accelerate the deterioration of hydraulic oil, oil life shorter.

The principle of electric hydraulic grab is to work through the hydraulic power system to achieve the opening and closing of the grab to achieve the purpose of loading and unloading of goods.

Causing the oil temperature rise Condition 1: the design of unreasonable electric hydraulic grab, grab the material, once the material resistance is greater than the grab of the digging force, the grab although the material can not be caught in the material pile "suffocated ", But the motor is still turning the grab, or even the motor" stall ", the hydraulic system in order to protect their own, are equipped with relief valve, when the pump through the relief valve high pressure overflow, oil temperature rose sharply. Energy is conserved, electrical energy into heat, oil heating.

Causing the oil temperature rise Case 2: the design of unreasonable electric hydraulic grab, loading and unloading operations, due to the operator's experience or line of sight and other factors, after the closure of the hydraulic grab to hold the handle, so grab the re-closed Often occurs), then the motor is still turning the grab, the motor appears "stall", the hydraulic pump through the relief valve high pressure overflow, oil temperature rose sharply. Energy is conserved, electrical energy has become a heat, to oil heating.

1, hydraulic grab work can not test, unsafe. Hydraulic grapple oil temperature is too high hazards such as hydraulic oil viscosity, volumetric efficiency and hydraulic system efficiency are reduced, leakage increases, pressure can not hold, the light grasping force smaller or can not afford to grab the goods, poor reliability, Of the cargo air fall, unsafe.

2, the impact of production. Hydraulic grapple high oil temperature hazards affect the loading and unloading efficiency.

3, the hydraulic system parts due to overheating and expansion, destruction of the relative movement of the original parts of the normal with the gap, resulting in increased friction resistance, hydraulic valve is easy to stuck at the same time, the oil film thinning, mechanical wear increased, resulting in pumps, valves , Motor and other precision with the premature wear and tear due to failure or scrap.

Grab

4, the oil vaporization, water evaporation, easy to make hydraulic components cavitation; oil oxidation formation of colloidal sediment, easy to plug the oil filter and hydraulic valve holes, so that the hydraulic system can not work properly.

5, to accelerate aging rubber metamorphic deterioration, shorten life expectancy, and even loss of its sealing performance, so that a serious leak hydraulic system.

6, hydraulic grapple oil temperature is too high hazards such as will accelerate the deterioration of hydraulic oil, oil shorten the service life.

7, hydraulic grapple failure rate, maintenance costs. High oil temperature will seriously affect the normal use of the machine to reduce the service life of hydraulic components, high failure rate, increased maintenance costs.
