4.5.4 During the operation of the filter, the support wheel should rotate flexibly and have good contact with the track. The number of support wheels in contact with the track should not be less than two-half of the total number, and it is not allowed that two adjacent support wheel surfaces are not in contact at the same time. 4.5.5 The orientation of the fixed staggered air plate should be consistent with the orientation of the guide rail. 4.5.6 The quality of the main purchased supporting equipment (reducer, electrical, etc.) should comply with the provisions of relevant standards, and can only be used in conjunction with the factory certificate.
4.6 Appearance quality
4.6.1 All welds should be uniform, flat and smooth, and the cutting edges should be free of welding slag and burrs. 4.6.2 The side of the filter bucket should be straight, without obvious waves, unevenness and defects that affect the appearance quality. 4.6.3 Non-processed metal surfaces shall be coated with anti-corrosion paint, and its quality shall comply with the provisions of JB/T7217. Parts with surface oxidation treatment and stainless steel parts shall not be painted.
4.7 Safety requirements
4.7.1 The filter shall have a rotation direction mark. 4.7.2 The open transmission device shall have a removable protective cover. 4.7.3 The electrical control box and the motor shall be reliably grounded. 5 Test methods
5.1 Kerosene leakage test
Clean the side of the weld that is easy to inspect, apply white powder, and dry it. Apply kerosene on the other side of the weld to ensure that the surface is sufficiently wetted. After 30 minutes, observe the inspection surface with white powder. It is qualified if there is no oil stain. 5.2 The noise test of the filter shall comply with the provisions of GB/T10894. 5.3 Idle running test
5.3.1 Before the idle running test, the following should be checked:
a) Material warranty or re-inspection report of main parts and components; b) The quality of main parts and components should meet the requirements of 4.4; c) Assembly quality should meet the requirements of 4.5; d) Appearance quality should meet the requirements of 4.6; e) Safety should meet the requirements of 4.7:
JB/T5282—1999
f) Major outsourced supporting equipment should meet the requirements of 4.5.6. 5.3.2 Operation requirements
During the idle running test, the motor should be started when the speed regulator is at zero position. After the motor is started, the speed should be adjusted from zero, from slow to fast, and the continuous operation should be no less than 4 hours.
5.3.3 The idle running test shall meet the following requirements: a) There is no magnetic friction and abnormal noise during operation;
b) The bearing temperature rise shall meet the requirements of 4.2.2: c) The noise of the filter shall meet the requirements of 4.2.3; d) The filter plate shall run smoothly, the tipping bucket shall be flexible, the displacement shall be correct, and the contact between the tipping fork roller and the guide rail shall be good. 6 Inspection rules
6.1 Inspection classification
Filter product inspection is divided into factory inspection (idle running test) and type inspection (all technical requirements specified in this standard shall be inspected) 6.2 Factory inspection
6.2.1 The filter shall be inspected for each unit, and the qualified product certificate shall be attached. 6.2.2 Factory inspection shall be carried out in accordance with 5.3.
6.3 Type inspection
6.3.1 Type inspection shall be carried out in any of the following cases: a) Trial production and identification of new products or old products transferred to the factory for production; b) Products that have undergone major modifications in structure, materials, and processes after formal production; c) When the national quality supervision agency proposes a type inspection requirement. 6.3.2 Type inspection shall be carried out in accordance with the provisions of Chapter 4 and Chapter 5. 7 Marking, packaging, transportation and storage
7.1 Marking
Each filter should be fixed with a durable label on a conspicuous flat part. The label size should comply with the provisions of GB/T13306. The label should indicate the following:
a) Model and name of the filter:
b) Main technical characteristics:
Filter area, m;
-Effective filter area, m\;
Speed, r/min
Power, kw;
Weight, kg;
c) Product number:
d) Manufacturing date;
e) Manufacturer's name.
7.2 Packaging
JB/T5282-1999
7.2.1The filter should be packaged in parts and corresponding assembly marks should be made on the disassembled parts. 7.2.2 The quality of filter packaging shall comply with the provisions of GB/T13384. 7.2.3 The graphic signs of filter packaging, storage and transportation shall comply with the provisions of GB191. 7.2.4 The exposed processing surfaces of the accessories, spare parts, special tools and main machine of the filter that may be corroded by the atmosphere shall be treated with anti-corrosion before packaging.
7.2.5 The following documents shall be attached to the filter when it leaves the factory: a) Packing list:
b) Product factory certificate (including the certificate of conformity of the main supporting electromechanical products): e) Installation and operat
