SK75-8 Electronic Pump Filter Element Bamboo Pilot Filter Construction Machinery Equipment Parts

Product Description:

The pilot filter element is an important component of protecting hydraulic oil in the mechanical industry. It can prevent impurities, mud, and other debris from entering the main control valve group. Cloudy hydraulic oil can reduce the flow rate in the pipeline, decrease the effectiveness of hydraulic organs, and even cause damage to hydraulic components in the machine industry. Therefore, the role of the hydraulic oil pilot filter element is very important.

During the long-term use in the mechanical industry, it is essential to replace the hydraulic oil pilot filter element. Timely cleaning, regular inspection, and replacement before replacement can effectively prevent debris from entering the hydraulic system and reduce the risk of poor oil filtration or system failure caused by aging or clogging of the filter element.

Although the hydraulic oil pilot filter element is small, its role cannot be ignored. It is an important component to ensure that our mechanical industry hydraulic oil system does not have problems. Therefore, we need to take its maintenance and repair seriously, and pay attention to the details of replacement to maintain the stable operation of the equipment.

Features:

1. The pilot control system has extremely high requirements for oil cleanliness, so the filtration accuracy of the pilot filter element is usually between 3-10 μ m, and some precision applications even require 1-3 μ m, which is much higher than that of ordinary hydraulic return oil or suction filter elements to prevent particles from sticking to the precision valve core.

2. Adopting high-strength skeleton (such as stainless steel mesh or 3D printed honeycomb matrix) and high-quality filter materials (such as glass fiber, synthetic fiber), with good axial stiffness and flattening stiffness, it is not easy to deform or collapse under impact load or alternating pressure, ensuring stable filtration accuracy
 

3. To avoid affecting the response speed of the pilot oil circuit, the filter element adopts a corrugated folding structure (usually with a pleat height of ≤ 20 mm) to increase the filtering area and reduce flow resistance. The initial pressure difference of some products can be controlled below 15 psi (about 0.1 MPa) to ensure rapid system response

4. The working temperature range is generally from -30 ℃ to+110 ℃, and some high-performance filter elements can withstand a high temperature of 135 ℃ for a short time, and are well compatible with commonly used hydraulic oils, phosphate hydraulic oils, water ethylene glycol and other media

5. Some high-end pilot filter elements are made of stainless steel material, with uniform pores and corrosion resistance. After cleaning, they can be reused to reduce replacement frequency; At the same time, it has good pollutant holding capacity, and the new three-dimensional fiber structure can increase the pollutant holding capacity by 30% -50%
