Hydraulic Oil Precision Filter Tester

The Hydraulic Oil Precision Filter Tester is a specialized filtration device for processing high-precision industrial oils such as hydraulic oil, anti-wear hydraulic oil, and heat transfer oil. It belongs to the category of oil purification and regeneration equipment and is widely used in industries such as petroleum, chemical, metallurgy, power, and machinery manufacturing. This equipment effectively removes impurities, moisture, gas, and metal particles from the oil through purely physical methods, thereby restoring the oil's performance and extending the service life of hydraulic systems and related equipment.

Applications

Filtration of hydraulic lubrication system during refueling.

● Bypass filtration of hydraulic lubrication system during operation.

● Circulation filtration of hydraulic lubrication system before operation.

● Hydraulic lubrication system oil is not filtered and pumped out by the pump of the equipment itself.

(Note: This machine is not applicable to flammable and explosive media such as fuel oil.)

Standards

NAS 1638 : Cleanliness Requirements for Hydraulic Fluids

ISO 4406: 2021 Hydraulic fluid power — Fluids — Method for coding the level of contamination by solid particles

GJB 420A-2006 : Classification of Solid Particle Contamination in Hydraulic Systems and Components

Features

1. Employs strong magnetic filter material for efficient adsorption and removal of metallic impurities such as iron filings;

2. Equipped with original imported polymer materials for thorough demulsification;

3. Combines coalescence separation technology with vacuum duplex three-dimensional flash evaporation process to significantly improve dehydration and degassing efficiency and thoroughness;

4. Utilizes internationally advanced multi-U-shaped gradually denser carbon fiber far-infrared heaters for uniform heating, high efficiency, and energy saving;

5. The entire filtration process is purely physical, without damaging the original properties of the oil or various additives; Strong wind cooling technology accelerates water vapor condensation and sedimentation, effectively protecting the stable operation of the vacuum pump.

Test Procedures

When the oil filter works for a period of time, the oil filter oil system pressure increases accordingly, the performance of its components have different effects, especially on the filter precision of the filter element of the shadow

core damage, the main reason for this is that the filter element of the differential pressure rises, the need to replace the filter element. Specific cleaning and replacement methods are as follows:

Cleaning: (only on the pump before the suction oil filter)

Cleaning cycle: oil filter continuous work for a week (about 150 hours)

a. Unscrew the top cover of the oil suction filter and take out the filter element.

b.Cleaning the filter element:When cleaning the filter element, soak it with gasoline for about half an hour and then remove the impurities with a brush.

Replacement

Conditions for replacement: When the oil filter is filtering, when the red indicator pops up on the differential pressure alarm installed on the pre-filter and fine filter, the cartridge needs to be

Replacement method: loosen the four bolts on the upper cover of the pre-filter and fine filter, remove the upper cover, take out and replace the filter element.

Precautions

The oil filter can not filter gasoline and other flammable liquids.

If the oil pool (or tank) of the oil is too dirty and there may be large obstacles, in the suction port should be installed on the large mesh filter protection.

The oil suction and discharge pipes should be kept clean.
