What type of hydraulic oil is there?

Hydraulic oil is an indispensable working medium in the hydraulic system, and its performance directly affects the operating efficiency and life of the equipment. Different types of hydraulic oil are suitable for different working conditions and equipment needs. This article will introduce in detail the common models, classification standards and application scenarios of hydraulic oil to help users better choose suitable hydraulic oil.

1. Classification standards of hydraulic oil

What type of hydraulic oil is there?

Hydraulic oils are typically classified according to their base oil type, viscosity grade, and service performance. The following are common classification criteria:

Classification criteriaDescription
Base oil typeMineral oil, synthetic oil (such as PAO, ester oil), semi-synthetic oil
Viscosity gradeISO VG (international standard viscosity grade), such as VG 32, VG 46, VG 68, etc.
Usage performanceWear resistance (HM), oxygen resistance (HO), low temperature performance (HV), etc.

2. Common hydraulic oil models and characteristics

The following are common hydraulic oil models and their characteristics on the market:

ModelViscosity gradeMain featuresApplicable scenarios
HLVG 32, VG 46Ordinary mineral oil, average antioxidant propertiesLow pressure hydraulic system
HMVG 32, VG 46, VG 68Strong anti-wear performance, extending equipment lifeMedium and high pressure hydraulic system
HVVG 32, VG 46Good low temperature fluidity, suitable for cold areasHydraulic systems in low temperature environments
HSVG 15, VG 22Synthetic oil with excellent high temperature stabilityHigh temperature or extreme conditions

3. How to choose the appropriate hydraulic oil

Consider the following factors when selecting hydraulic oil:

1.Viscosity grade: Select according to the equipment manufacturer’s recommendations or working conditions. For example, VG 46 is suitable for most medium voltage systems.

2.temperature range: For low-temperature environments, choose the HV model, and for high-temperature environments, choose the HS model.

3.Device type: Precision equipment requires anti-wear type (HM), and ordinary equipment can choose HL type.

4.Environmental requirements: Synthetic or biodegradable oils are more environmentally friendly, but cost more.

4. Precautions for using hydraulic oil

1. Change hydraulic oil regularly to avoid oxidation and contamination.

2. Different types of hydraulic oil cannot be mixed to avoid chemical reactions.

3. Avoid direct sunlight and humid environment when storing.

4. Check the cleanliness of the oil before use and filter it if necessary.

5. Summary

The type selection of hydraulic oil directly affects the performance and service life of the equipment. Users should select the appropriate hydraulic oil model based on actual working conditions, equipment requirements and environmental conditions. For further information, it is recommended to consult a professional supplier or equipment manufacturer.
