No. Servo system 68 is hydraulic oil and servo way 68 is lubricant
servo system 68
engine oil is thick than hydraulic oil
There is no difference that I am aware of. These terms seem to be used interchangably.
Servo 46 is a hydraulic oil that typically has a viscosity of ISO 46. This means it has a viscosity range of 41.4 to 50.6 cSt at 40°C. It is a medium-viscosity oil suitable for a wide range of hydraulic applications.
Normally, universal testing machines have a moveable struture which can vertically move up and down to realize both tensional and compressional tests. Tensional tests include tensile, tear and peel tests Compressional tests include compressive, shearing, bending and flexural tests Universal testing machines can be classified into two categories daccording to their driving methods: servo-hydraulic drive and electromechanical drive. Servo-hydraulic: it has a tensile structure mounted on a oil cylinder which is used to drive the tensile structure up and down, and the oil feeding rate to oil cylinder is controlled by a servo valve. such as HUALONG servo-hydraulic universal testing machine Electromechanical: it has two screws and a moveable crossbeam, the crossbeam could move up and down to achive tensile and compressional tests, a servo motor which is contrlled by a servo drive to drive the crossbeam up and down. such as HUALONG electromechnical universal testing machine
Basically, the only difference between HD-46 and HD-68 hydraulic oils is the weight of the product. HD-46 is a 15 weight oil, but HD-68 is a 20 weight oil.
Hydraulic fluid and hydraulic oil are one in the same.
