6 Test method
The test prototype is fixedly installed on the foundation or on a special test bench for testing. 6.1 Tightness of the filter chamber of the whole machine
6.1.1 The whole machine is pressed with the rated force when there is no gasket between the sealing surfaces. Use a feeler gauge to check the gap between the sealing surfaces and take the larger value.
6.1.2 The filter medium with a thickness of no more than 15mm or the gasket required by the design can be used between the sealing surfaces. Tighten with the rated force. The liquid outlet of the group, the outlet box is equivalent to the water sheet with a pressure of 125, and the pressure is maintained for 5 seconds. Check the tightness of each pair and the necessary connection. The compression force of the manual and mechanically compressed filter press is measured by a force measuring instrument. 6.1 Strength of each variable component
When there is no gasket between the sealing surfaces, the machine is pressed with 1.25 times the compression force, and the pressure is maintained for 5 seconds. Unload the filter! , check the damage of each pressure-bearing part, measure the clamping force of the manual and mechanical clamping machine with a force measuring instrument, 6.3 Apply 1.25 times the fixed pressure to the liquid tightening device, and observe the pressure drop within 20% after the pressure is applied. Check the parts and components of the clamping device and the tightness of the joints. 6.4 Liquid system cleanliness
Test the system cleanliness according to the provisions of JR/T6418. 6.5 Noise
Test the noise according to the provisions of GB[08.
6.6 Reliability of control device and actuator The reliability test of the control device actuator should be carried out under no-load operation during the replacement operation process. For the complete machine equipped with automatic heat-travel mechanism, each action of the automatic control program should be adjusted to the position with the shortest cycle time for testing. The filter plate pull-out mechanism: open once, operate continuously for 10 times; the filter plate is pressed open, and the reverse cycle is operated 10 times. For the filter with dynamic resistance across the plate, the tightening device is operated continuously for 5 cycles.
G. Mechanical properties of welds
JB/r8104-1999
.7.1 Sampling for mechanical properties test of weld chain shall be in accordance with the provisions of GD/T2649.6.7.2 Impact test of weld test shall be in accordance with the provisions of GB/T2650.6.7.3 Extension test of weld test shall be in accordance with the provisions of GB.T2651.6.7.4 Bending test and shoulder test of weld test shall be in accordance with the provisions of GB/T2653.6.7.5 Corrosion test of austenitic weld chain shall be tested and evaluated in accordance with the provisions of B/14334.1-4334.5.6.8 Filter performance
For filter machine with uniform filter selection, the filter belt shall run continuously for 3 circles at the maximum running speed. For endless filter belts that are movable, measure the deviation at the thrust plate and the opening, and collect the maximum value; for endless filter belts that have a small circulation, measure the deviation at the top, and collect the maximum value of 6. Minimum filter plate, feed plate, and depth tolerance: The smaller the filter plate, the smaller the error in the filter depth. Select the feed plate horizontally, and select eight locations on the sealing center line, i.e., the four sides of the square filter plate, the middle of the four sides of the drive plate, and the evenly distributed round filter plate and filter cabinet (when measuring the depth error of the filter plate, the inner edge of the eight locations should be extended 50-120mm to the center). Use a flow meter or other special measuring tool to place two data at each location: except for the special screening point, the maximum value is 6, and the surface roughness of the cover of the filter plate, the pressure plate, the thrust plate and the material plate should be in accordance with B/T6060.2 and the provisions of GB/T10610 6. The strength of the diaphragm, that is, the tightness of the diaphragm
Put a filter unit with a commercial membrane on the test bench (see Figure 1 and Figure 2. Figure 1 is the inflation test, Figure 2 is the water-filled test bench. When the feed is loaded, the filter cavity is kept empty or filled with other materials) and the rated compression is pressed to the maximum. Then, a suspension that is the same as or similar to the actual material is introduced into the filter chamber at a rated low force for drainage (the filter chamber can also be kept empty or filled with other materials. After filtration, the diaphragm cavity is inflated with air (water) at the squeezing pressure, and then the pressure is released to make the pressure in the diaphragm equal to that in the pressure in the diaphragm. The second inflation is performed with water) and the pressure is maintained. This is repeated for three times. After the above test, the diaphragm cavity is inflated with air (water. When the layer pressure is reached, , turn off the idle air (water), and observe the pressure drop within 2. Check the filter assembly: Check the damage:

6.12 Strength and sealing of filter plate and filter frame
6.12.1 Filter plate, frame sealing and filter strength will be a need The filter unit to be tested (there must be a through hole on the filter surface of the filter plate to facilitate the simultaneous lateral pressure test on both sides) is installed on the test bench [see Figure 31, with 1.25 times the rated pressure, and then input 1.25 times the rated pressure into the room, keep it for 1 minute, check the sealing condition of the filter outlet connection of each cover, close the stop valve 4, observe the pressure drop within 2m, remove the filter unit, check the filter plate through the block, filter condition: once described: 2-no pump; 3-natural return: seven energy stop cause, 5 positive force clothing 6-stop plate: one-way test of the reduction unit: B-no source report figure
6.12.2 Filter plate leakage surface strength
612.2.1 Put a filter unit to be tested (there must be no leakage surface The filter unit that has passed the test in 6.13.2 is installed on the test bench (see Figure 3). It is compressed with a certain pressure, and then water with a pressure of 0.1 times the rated filtration pressure is input into the single-sided filter chamber. After removing the filter plate, check the damage of each plate. Replace the filter plate on both sides and repeat the above test. 3B/8104—1999
6.12.2.2 Install a filter unit made of plastic that has passed the test in 6.13.2 on the test bench (see Figure 3). It is compressed with a certain pressure, and then water with a pressure of 0.4 times the rated filtration pressure is input into the single-sided filter chamber (it is allowed to fill part of the solid matter in the lead-in period). After 2 minutes, the filter plate is removed and the damage of each plate is checked. Replace the plate surface and repeat the above test.
