What hydraulic oil is used for Denison hydraulic pump? What are the requirements

DENISON No hydraulic fluid is produced for hydraulic pumps , Based on the experience of the past few years , Some hydraulic oils are used for DENISON Hydraulic pump , Its working performance is better than other types of hydraulic oil . However , There are so many hydraulic oils available on the market , As a result, it is impossible to determine whether each type of hydraulic oil can be applied to DENISON Test the hydraulic pump . Today, Ningbo Sicheng will talk about DENISON What technical requirements do hydraulic pumps have for hydraulic oil .

Viscosity index

Viscosity index （V.I.） It is used to measure the change of oil viscosity with temperature . When the viscosity index is large , In the process of temperature change , The smaller the change in oil viscosity . For fluids ,DENISON Require to have 90 V.I. Minimum viscosity index . A large viscosity index can extend the operating temperature range of the engine oil , But at this time , The shorter the life of the oil .

Operating temperature range

The operating temperature range depends on the viscosity of the oil 、 Type and tightness . The operating temperature of rapeseed oil base oil shall not be lower than -20℃.

Application in cold climate

DENISON The operation of hydraulic pump in low temperature environment requires special consideration . If there is no suitable multi viscosity oil , Different oils can be changed according to weather conditions , Or modify the system equipment to keep it at the proper viscosity .
