Scissor lift the quality of how to identify system components
Scissor lifts hydraulic components for lifts operating results have an important impact, and its impact on the operation of the scissor lift, affecting the life of the scissor lift. So how do we hydraulic components through temperature, pressure, determine good or bad?
Relevant parts of the test system with a gauge pressure is a common method for detecting faults. Why should we choose gauge testing system? According to the hydraulic system of the working mechanism, after wear related components, the pressure value some changes. In addition, we can also measure the flow of hydraulic components using internal leakage and volumetric efficiency, detect whether there is obstruction of the hydraulic circuit.
When the lift's hydraulic components but can not produce excessive internal heat when fully distributed, scissor lifts hydraulic components to malfunction. Hydraulic components mainly caused by the cutting surface temperature heat, friction caused by heat, both of which are associated with damage to the element. Under normal circumstances, the hydraulic component surface temperature about 50 ℃, after the failure of the temperature can be increased to above 80 ℃. Therefore, the use of the test surface temperature of hydraulic components, hydraulic components for hydraulic lifts to make comprehensive diagnosis.
