37 -41
Machine internal parts
5.1 The pressure leaf filter shall comply with the requirements of this standard and be manufactured according to the drawings and technical documents approved by the prescribed procedures. The materials and purchased parts of the parts shall have the inspection certificate of the manufacturer: if there is no certificate, the manufacturer shall conduct an inspection and the qualified ones shall be 5. 2
Use.
[B9097—1999
5.3 The parts shall comply with the provisions of GB/2100, AB.T[4408 and GB/T9439. 5.4 The structure of the filter shall comply with the relevant provisions of GB150. 5.5 The surface of the filter blade shall be flat; the weld chain at the bottom edge of the filter blade shall be subjected to the kerosene filling test and shall not leak. 5.6 After the filter blades are assembled, the filter blades shall be parallel, and the sealing parts of the filter blades and the filtrate collecting pipe shall not be connected. 5.? The idling device, material device and control device shall be tested for dry operation, and the action shall be accurate and reliable. 5.8 The outer surface of the pressurized blade (except for the surface of stainless steel parts) shall be painted. The coating quality shall comply with the provisions of B/T2536.
5.9 The filter should be subjected to a water pressure test at 25 times the design force. There shall be no leakage or unloading at the sealing of each component. There shall be no obvious deformation or damage to the components. 5.1 During the load test, the actual working cycle time, separation effect (including the properties and composition of the suspended liquid), filter content, and production capacity shall all meet the design requirements. 5.11 In addition to complying with the provisions of this standard, the filter that handles toxic, flammable, and explosive materials shall also comply with the relevant provisions of the "Regulations on the Supervision of the Installation of Furnace Containers".
6 Test methods and inspection rules
6. 1 Test method
6.1.1 Coal leakage test
Clean the side of the weld that can be inspected, wipe it with self-powder, dry it, and then apply baking soda on the other side. The surface is not moistened enough. After 0.5h, the white powder and oil stains are qualified. 6.1.2 Idle operation test
The unloading device, the top benefit device and the control device are idling for 5-10 seconds. 6.1.3 Pressure test
The water pressure test pressure is 1.25 times the design pressure, and the maintenance time is not less than 3min. Check the condition of each sealing part. If there is leakage in the connection part, it should be retested. After the pressure test, the water should be drained and the internal pressure should be purged with compressed air. The pressure gauge is level 1, and the selected pressure gauge should make the test positive pressure above 1/3 of the full scale value of the pressure gauge. 6.1.4 Negative test
6.1.4.1 The material used for the test shall be selected and determined by the manufacturer. 6.1.4.2 Load test: The operation cycle shall be no less than 10 times under rated conditions. 6.1.4.3 The following data shall be measured in the load test: a) The actual operation cycle time of the positive leaf filter; b) Separation effect, including the properties and composition of the suspended liquid, the solid content of the filtrate and (or) the liquid content of the cake; and the production capacity of the leaf filter.
6.2 Factory inspection and type inspection
6.2.1 The pressurized leaf filter shall be subjected to factory inspection and type inspection. Each pressurized leaf filter shall be inspected before delivery. Only after passing the inspection can it be delivered. Type inspection shall be conducted in the following cases: 1) Technical appraisal of new product trial production:
JB/T 9097—1999
b) After formal production, the structure, materials and process have changed greatly, which may affect the product performance: u) During the production, 1-2 units shall be inspected every year; when the inspection result is greatly different from the last type inspection. 6.2.2 Factory inspection
The inspection shall be conducted in accordance with the provisions of 5.5, 5.6, 5.7, 5.8 and 5.9. 6.2.3 Type inspection
In addition to the inspection in accordance with the provisions of 6.2.2, the type inspection shall also be conducted in accordance with the provisions of 5.10. ? Marking, packaging, transportation and storage
