Schwing Stetter Hydraulic Oil Purchase And Maintenance Method

Hydraulic oil has become an indispensable part of the hydraulic system because it can transfer energy, reduce friction to lubricate the hydraulic system, and prevent the hydraulic system from rotting and rusting, and at the same time play a cooling role. In the selection of hydraulic oil, the first thing to consider is the requirements for the viscosity of the hydraulic device at the operating temperature and the starting temperature. The reason why its viscosity needs to be considered first is because the viscosity change of the lubricating oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy. At the same time, there are also requirements for the viscosity-temperature performance and shear stability of the oil, which need to meet the various requirements of different uses. There are many types of hydraulic oils on the market, and the classification methods are also similar and different. When purchasing, you can choose the most suitable product according to your needs.

In addition to a brief introduction and selection requirements, Elephant Fluid Power will also introduce you to some precautions for hydraulic oil maintenance from 5 aspects.

1. Ensure that the hydraulic oil is not used at high temperature; The oil quickly oxidizes and deteriorates at high temperatures.

2. The air filter on the hydraulic station should use a filter that can filter both particles and moisture.

3. The use of precision filter element to filter hydraulic oil, so that the pollution degree of oil products is maintained at NAS <8 level for a long time, and the filter element that comes with the equipment is generally too accurate to ensure the cleanliness of the hydraulic oil.

4. Centrifugal dehydration/vacuum dehydration (for oil stations with moisture).

5. Do oil testing regularly

Hydraulic oil in the process of use inevitably to experience the change of four seasons, cleanliness has also become the performance requirements of oilgear pump parts, the general product to NAS particle size level is not more than 9, clean products are not more than 7, high cleaning products are not more than 5, but blind pursuit of NAS grade not only has no effect, but reduces quality, increases cost.

6. Prevent air from entering the oil

The oil suction port of the oil pump should be sealed reliably, the oil suction pipe in the oil tank should not be too close to the oil surface, and the highest point of the system should be equipped with an exhaust valve to release free air in the oil.

7. Reasonable design of fuel tank

The oil suction pipe should be kept away from the oil return pipe, avoid the use of lead, zinc, copper and other materials that play a catalytic role in the oxidation of the oil, the oil tank should be coated with oil-resistant anti-rust paint, and the cooler in the oil tank should not leak.
