QU-H100X3BDP return oil filter cartridge

Features Parameters Related

The QU-H100X3BDP return oil Filter Element is installed in the return oil pipeline of the hydraulic system to filter the hydraulic oil flowing back to the oil tank from various components of the system. It can effectively filter out metal debris, dust, rubber particles, and impurities such as gum generated by oil oxidation during use, preventing these pollutants from entering the hydraulic system again and contaminating the clean oil in the oil tank, thereby protecting precision components such as hydraulic pumps and valves and extending the service life of the hydraulic system.

The QU-H100X3BDP return oil filter cartridge has the following characteristics:

Excellent filtering performance

-High precision filtration: With a filtration accuracy of up to 3 μ m, it can effectively intercept small impurities such as metal debris, dust, rubber particles, oil oxidation gum, etc., providing high standard oil return cleanliness for hydraulic systems and protecting precision components inside the system.

-Strong pollutant absorption capacity: High quality filter materials are used, such as deep folded glass fiber filter materials, which have a large specific surface area and complex pore structure, increasing the space for impurity containment, extending the service life of the filter element, and reducing the frequency of replacement.

Adapt to high-pressure working conditions

The "H" in the model indicates that it is suitable for high-pressure hydraulic systems, capable of withstanding high-pressure environments during system oil return, maintaining structural stability and filtration performance, and will not cause damage to filter materials or a decrease in filtration efficiency due to pressure fluctuations.

Good traffic adaptability

The rated flow rate is 100L/min, which can meet the corresponding flow requirements of the hydraulic system for smooth oil return. It will not cause poor oil return due to filter elements, resulting in excessive back pressure in the system, ensuring normal operation of the system.

Equipped with blockage alarm

The blockage signaling device with the "D" symbol will send a signal (such as color change, electrical signal output, etc.) when the filter element is gradually blocked by impurities and the pressure difference between the inlet and outlet reaches the set value, reminding the operator to replace the filter element in a timely manner to avoid affecting the normal operation of the system due to excessive blockage of the filter element.

Stable and durable structure

-Sturdy skeleton support: The skeleton is made of high-strength carbon steel or stainless steel materials, providing reliable support for the filter material. Under high pressure and high flow conditions, it can ensure that the filter element does not deform or damage, and maintain normal filtration function.

-Good sealing performance: A reliable sealing design is adopted between the end cap, filter material, and skeleton to prevent unfiltered oil from bypassing, ensuring that all return oil is filtered through the filter material and guaranteeing the filtering effect.

Easy installation and maintenance

-Easy installation: Designed to meet universal installation standards and compatible with common hydraulic system return oil pipeline interfaces, the installation process is simple and fast, effectively reducing installation time and labor costs.

-Easy maintenance: When the blockage signaling device sends a replacement prompt, the filter replacement operation is simple, and a new filter can be quickly installed, shortening the equipment shutdown maintenance time and reducing the impact on production operations.

Technical Parameter

The technical parameters of QU-H100X3BDP return oil filter cartridge are as follows:

Filter parameters

-Filtering accuracy: 3 μ m, capable of effectively intercepting particles and impurities with a diameter greater than 3 microns, such as metal shavings, dust, rubber particles, etc.

-Pollutant holding capacity: Depending on the filter material and structural design, it is generally within a certain range, such as around 500g-1000g. The specific value varies from manufacturer to manufacturer, representing the total amount of impurities that the filter element can hold before replacement.

-Filter material type: usually made of glass fiber material, which has the characteristics of efficient filtration and large pollutant holding space; Stainless steel woven mesh may also be used, which has good strength and corrosion resistance.

Flow and pressure parameters

-Rated flow rate: 100L/min, which means that under normal working conditions, the volume of oil that can pass through the filter element per minute is 100 liters, ensuring smooth oil return.

-Initial pressure difference: In the brand new state of the filter element, the pressure difference between the inlet and outlet when the oil passes through is generally small, usually between 0.03-0.05MPa.

-Maximum working pressure: The maximum pressure that the system can withstand, generally between 16-31.5MPa, is suitable for high-pressure hydraulic systems, and the specific value depends on the product design.

-Blocking signal pressure difference: When the filter element is blocked to a certain extent by impurities and the pressure difference between the inlet and outlet reaches the set value, the blocking signal device will send a signal to prompt the replacement of the filter element. The set value is usually between 0.3-0.4 MPa.

Working environment parameters

-Working temperature range: The common working temperature range is -10 ℃ -+110 ℃. Different materials of filter materials and seals may cause differences in temperature range. Within this temperature range, the filter element can perform its filtering function normally.

-Applicable media: mainly suitable for various mineral oil-based hydraulic oils, synthetic hydraulic oils and other common hydraulic working media.

External structural parameters

-Dimensions: including the diameter, length, and other specific dimensions of the filter element. Different manufacturers may produce different filter elements, which generally need to be determined by referring to the product specifications. For example, the diameter may be between 60-100mm and the length may be between 200-400mm.

-Interface form: Common interface forms include threaded interfaces, flange interfaces, etc., which facilitate connection with the return oil pipeline of the hydraulic system.
