JB/T 5239.4-2016 Diesel engines-Diesel filters-Part 4: Test methods;

JB/T 5088.2-2018 Internal combustion engines-Spin on oil filters-Part 2: Test method;

JB/T 5089.3-2010 Internal combustion engines-Paper element oil filters-Part 3: Test method;

ISO 2942-2018 Hydraulic fluid power-Filter elements-Verification of fabrication integrity and determination of the first bubble point;

【Technical Parameters】

• Test medium: Isopropanol, 180L;

• Precision pressure regulating valve pressure range: 5 kPa-200 kPa, Accuracy: 0.5%;

• Pressure sensor range: 0-10 kPa, Accuracy: 0.1%;

• Temperature sensor range: 0-100℃, Accuracy: ±1℃;

• Maximum test piece dimension: H≤350mm, Φ≤200mm;

• Decision condition: According to JB/T 5239.4-2011, the initial bubbling pressure is not less than 1.0kPa;

• Overall parameters: 

  The test piece is lifted automatically by combination of reducer and screw;

  The control part is controlled by PLC and the human-machine interface is controlled by touch screen. The test is carried out through data setting;

  The overall test is divided into automatic/manual functions;

• Equipment dimension: 1500mm×810mm×1800mm (LengthXwidthXheight) (mm);

• Equipment power: Three phase five wire, AC380V, 1.5kW;

• Net weight: 380kg;

【Product Advantages】

• Equipment housing: The overall use of sheet metal spray-molded housing, industrial design of appearance, ergonomic operation, stainless steel operating parts of internal test pieces;

• Air supply system: Air is supplied by fixed air source. First, it is decompressed and filtered by regulator and lubricator, after three-stage filtration, it is filtered by macromolecular membrane air dryer. Secondary decompression is required. Primary decompression is pressure regulation of precision decompression valve. Secondary decompression is pressure reduction of large-bore gate valve, so that air pressure reaches low pressure stability. Air pressure is collected by precise low pressure pressure sensor with high adjustment accuracy;

• Lifting system: With ball screw system, high positioning accuracy can be obtained, the lifting system can be positioned accurately, it is equipped with worm and gear reducer with self-locking function to ensure that the test platform does not slip during the static test;

• Rotating system: With self-made rotating device and driven by rotation, the seal is reliable and compact. Select high-quality rotary joint to ensure air tightness during filter element rotation. Stainless steel structure is used on the working table of test bench and hollow shaft connected with rotary joint;

• Test vessel: Stainless steel tank;

• Pipeline and joints: The pipeline uses a combination of air tube and stainless steel tubing. The joints use lock nut straight joint, quick plug joint and stainless steel tubing joint;

• System information collection: PLC automatic pressure, temperature and other synchronous acquisition and display functions;

• Information input and output: Test parameters can be inputed manually, and test reports can be generated synchronously and stored automatically by the system for quantitative analysis. History inquiry function; Report printing function;

• Operation and control: Automatic/manual function selection; Automatic: PLC automatic control after input of test parameters, including automatic adjustment functions of lifting, rotating, pressure and other parameters; Manual: Manual control;

• Safety measures: Emergency stop button, motor abnormal stop alarm, over-pressure stop alarm and other measures;

【Control System】

• With beautiful and convenient man-machine interface;
• Test conditions can be changed and test parameters can be updated as required;
• Dynamic display of condition parameter value and measurement parameter value can be realized;
• Communicate with monitoring system to check the test progress in real time;

what is Filter Test Bench

A filter test bench is a device that is used to evaluate the effectiveness and efficiency of a filter. It is an essential tool for manufacturers and designers to use in order to ensure the quality of their products. The test bench exposes the filter to a variety of settings and pollutants, imitating real-world scenarios and confirming its ability to execute its intended purpose.
Typically, the filter test bench comprises subjecting the filter to a battery of tests, including pressure drop and flow rate testing and strength tests, and endurance tests. These tests are designed to assess the filter's capabilities under various settings and ensure its overall performance.
Finally, a filter test bench is a crucial tool for manufacturers and designers in guaranteeing product quality. It guarantees that filters function successfully and efficiently in real-world circumstances, providing customers with increased trust in the items they buy.
