The method of determining the filtration efficiency of the filter element is as follows: The injection time H will vary with the test filter exposure and the test flow rate. This evaluation method can be used to determine the instantaneous or single-pass efficiency of the test flow device when it is in use. Note: The efficiency of the test flow changes with time, so the instantaneous or single-pass efficiency may not be the same as the original efficiency during the service life. 2.3.2 Before the test bench is put into the energy efficiency test, the test clean flow must be combined with the test flow to ensure that the results are not affected by the residual impurities in the test film. The total impurity content of the test sample is not more than m.2.5.2.1. The following requirements are met. Only a new clean flow filter is installed in the test line instead of the test filter and all the test fluid is released. Put enough suitable flushing oil into the test bench system box, so that the test case will not be empty during this cycle, and there will be no danger of flushing through the entire test system, including the oil source flowing through the tool. When flushing, the surface rate should be as low as possible, and the clean flow or cleaning should be able to remove impurities with maximum efficiency.

3.1 Characteristics of the work to be evaluated
Technical test table is to evaluate the filter's ability to remove harmful destructive cycles existing in the system. During the use of the filter, various impurities from micro-particles to large particles are blocked after replacement. Therefore, the surface of the filter can be blocked by the particles. Therefore, this performance has been fully considered when formulating this test specification. In the test system, the filter is tested for age and the efficiency of the filter is determined. When the filter is tested on a bench, there are many differences in the performance of the filter. When it is installed on the engine, the different working characteristics will make the filter components have obvious differences during the bench test. The test bench is used to verify the cost of the filter. The test bench should include all the small parts, so as to meet the requirements of the connection, support, etc. 3.2.2 The oil pump should be able to store the specified amount of oil and should be equipped with a standard heater (a typical cooler may be required to maintain the test temperature). The width of the heater should avoid local overheating: when the machine is in the training cycle: the filter outlet pipe is the return pipe to the tank, and the entire end should be lower than the "beat value". The humidity should be adjusted to keep the specified test viscosity within the range of 3m\.
3.2.3 The type of oil pump should be stable and the distribution of impurities should be stable. Note: The new material must be suitable for this industry so that it will not cause "over-damage to the oil policy". 3.2.4 The valve 3 in Figure 5 should be adjusted to the speed control plan as follows: the position meter or the end piece width should be set.

And add 50ruL of flow test wave to the file: 3.6.3.7 Place the pre-made blue in the block cup The oil mixed slurry (see 8.5.2.2) is automatically drawn into the oil tank: pre-ready and ready to be sent into the engine to remove impurities (previously recorded in C): at this time the slurry is continuously stirred at a speed of about 1001/:
3.6.3.8 Within 2, take 50m2 oil samples every 20mur. During the sampling interval, the oil age in the oil tank shall be adjusted to the adjustable value according to the provisions of Appendix 1.
3.6.3.9 Follow the provisions of Appendix 1 for the oil column. 3.6.3.10 The new impurities in the sample can be seen in the relationship diagram of the increase or decrease of impurities. The shape should be a straight line, and the length of the full-length dosing agent should be connected together to minimize the disadvantages of the item and the quality of the impurities. The theoretical distance between any point is also important for the practice of the beauty system. For the dry needle expansion injection or pressure disturbance of the transfer device or the purifier, the mouth can be connected together to minimize the disadvantages.
