F-type stainless steel gear pump maintenance and care

F-type stainless steel gear pump maintenance and maintenance: 1. All kinds of air gear pumps, efficient air gear pump before installation, do not allow to tear or open bags or packaging film by hand; should be strictly in accordance with F-type stainless steel gear pump box The standard direction of annotation is to store the air gear pump. During the handling of the efficient air gear pump, it should be lightly handled and avoid violent vibration and collision. 2. For F type stainless steel gear pump, the installation direction must be correct: with a corrugated plate gear pump installed in the vertical installation, the corrugated board must be perpendicular to the ground; gear pump in the vertical connection between the frame, no leakage, deformation , Damage and leakage of plastic, etc., after installation must ensure that the inner wall clean, no dust, oil, rust and debris. . 3 test methods: observation or white silk wipe check. 4. Before installation, the clean room must be fully cleaned, wiped clean air purification system if there is dust inside, should be cleaned again, wipe clean to meet the cleaning requirements. If F-type stainless steel gear pumps are installed in technical mezzanines or suspended ceilings, the technical floor or suspended ceiling should also be thoroughly cleaned and wiped clean. 5.F stainless steel gear pump transport and storage should be in accordance with the direction of the factory logo shelved. In the transport process, should be gently, to prevent violent vibration and collision, can not force loading and unloading. 6.F type stainless steel gear pump before installation, you must unpack the installation site for visual inspection, including: filter paper, sealant and the framework for damage; side length, diagonal and thickness dimensions to meet the requirements; whether the framework Burrs and rust (metal frame); with or without product certification, technical performance is in line with design requirements. Then in accordance with the national standard "Clean Room Construction and Acceptance Code" [JGJ71-90] the provisions of the method of inspection, qualified should be installed immediately. 7. F-type stainless steel gear pumps with cleanliness class equal to or higher than Class 100 clean room should be leak-tested according to the provisions of "Cleanroom Construction and Acceptance Specification" (JGJ71-90) before installation and meet the requirements . 8. When installing the F-type stainless steel gear pump, the arrow on the outer frame should be in the same direction as the airflow; when it is installed vertically, the crease direction of the filter paper should be perpendicular to the ground. 9. Install rough flat or folding gear pump, galvanized mesh should be in the back of the wind direction. The installation of bag gear pump, the length of the filter bag should be perpendicular to the ground, not parallel to the direction of the filter bag installed; 10. Under normal conditions, flat, folding coarse or medium efficiency gear pump, the general 1- March replacement, less stringent requirements of the area, the filter can be replaced with water after cleaning with detergent soaked, rinsed, then dry and then replaced; general flush 1-2 times, you must replace the new gear pump , In order to guarantee the filtration efficiency. 11. Bagged coarse or medium efficiency gear pump, under normal conditions of use (an average of 8 hours a day, continuous operation), the general use of 7-9 weeks should be replaced with a new one. 12. For sub-F stainless steel gear pump, under normal conditions of use (an average of 8 hours a day, continuous operation), the general use of 5-6 months, should be replaced. 13. For the above gear pump, if the gear pump before and after the pressure gauge or differential pressure sensor, the rough gear pump, when the pressure difference is greater than 250Pa, it must be replaced; for the efficiency gear pump, then the pressure is greater than 330Pa, it must be replaced; for sub-F stainless steel gear pump, when the pressure difference is greater than 400Pa, it must be replaced, and the original gear pump can not be reused; 14. F-type stainless steel gear pump, when the gear pump resistance When the value is greater than 450Pa; or when the air flow velocity to a minimum, even if the replacement of coarse, medium efficiency gear pump, the air flow rate can not increase; or F-type stainless steel gear pump surface leaks can not be repaired , Are required to replace the new F-type stainless steel gear pump; if not the above conditions, generally according to the conditions of the use of the environment, 1-2 years replacement. 15. In order to give full play to the role of gear pump, selection and use of the process, gear pump head wind, rough efficiency, efficiency gear pump should not exceed 2.5m / s, F stainless steel gear pump and F stainless steel gear pump Should not be greater than 1.5m / s, this will not only help to ensure the efficiency of the gear pump, but also extend the service life of the gear pump, cost savings. 16. In the equipment operation, generally do not replace the gear pump; And can not be shut down to replace, only allow continuous replacement of rough, medium efficiency gear pump; sub F-type stainless steel gear pump and F-type stainless steel gear pump to stop before the air can be replaced. 17. The seal between gear pump and connecting frame must be tight and leak free to ensure the filtering effect. 18. For the F type stainless steel gear pump to be used in high humidity and high temperature environment, we must select the filter paper and the separator plate and frame material with high temperature resistance and high humidity resistance to meet the production requirements. 19. Biological clean room and medical clean room, you must use the metal frame F-type stainless steel gear pump, and its surface is not easy to rust, wood framed gear pump is not allowed to prevent bacteria, affect the product's eligibility.
