For a long time after the appearance of the pneumatic diaphragm pump, many customers and potential customers of our company have many inappropriate ways of using the stainless steel pneumatic diaphragm pump safely and correctly. Today we have summarized After the problems encountered in the past, we have summarized some of the contents, and we have summarized the problems we have encountered so far. The stainless steel pneumatic diaphragm pump is a volumetric pump that is driven by a compressed air source and enters through the air inlet and reciprocally deforms through the diaphragm in the diaphragm pump chamber. The working principle is similar to that of the reciprocating pump.
Pay attention to the following points when using stainless steel pneumatic diaphragm pumps:
First, ensure that the large particles of zui contained in the medium will not be larger than the size of the pump.
Second, the intake pressure can not exceed the allowable operating pressure of the diaphragm pump. Excessive pressure of compressed air can cause the diaphragm to rupture and damage the service life of the pump. Zui may cause serious shutdown and personal injury.
Third, ensure that the outlet pressure of the diaphragm pump can accept the high output pressure of the Zui in the outlet pipe, and ensure the cleaning and normal working environment of the driving gas source pipeline.
4. Before the diaphragm pump is put into production, make sure that the grounding screw of the pump foot is firmly fixed to the ground. In order to prevent static sparks during use, the wire design should be adopted. The pump foot of the pump body should be grounded to avoid personal injury. Accident and property damage.
5. Before the diaphragm pump is put into production, the connecting pipe and joint of the diaphragm pump must be tightened to prevent sparks generated by the oscillation, impact and friction generated by the operation, and sparks are generated to prevent serious accidents. . The air intake nozzle is ideally an antistatic hose.
6. The grounding fixing technical requirements of the pump foot must comply with local laws and regulations and the special requirements of the site environment.
7. Regularly check and test the reliability of the grounding bolt and the ground fastening point. The grounding resistance must be less than 100 ohms.
8. It is necessary to maintain good exhaust and ventilation of the site environment, away from inflammable and explosive materials and heat sources.
9. When the diaphragm pump is in operation, since the compressed compressed air source may contain solid particles, do not point the exhaust port to the working area or humans to avoid unnecessary personal injury.
10. When the diaphragm is broken, the transported medium may leak from the exhaust muffler.
11. When transporting flammable, explosive or toxic and hazardous media, please connect the outlet to a safe area away from the work area.
Twelve, please use the zui less 3/8" inner diameter, the inner wall of the smooth pipe to connect the exhaust muffler.
13. If the pressure of the pump and the leakage of the medium during operation may cause personal injury or property damage, please do not perform any action on the pump and the material tube when the pump is running. For the change, please close the input of the medium, then open the bypass pressure relief valve to discharge the pressure in the outlet pipe, and then clean the pipeline with the pressure of the inlet source, and then slowly loosen the joints of the pipes.
14. If the diaphragm pump is a harmful toxic medium, please do not send the pump directly to the factory for repair. It must be properly arranged according to local laws and regulations, and use the genuine diaphragm pump accessories provided by Shanghai Nengyu Pump Valve Manufacturing Co., Ltd. to ensure the service life of the diaphragm pump.
15. Before running the stainless steel pneumatic diaphragm pump, it must be confirmed that the fluid components such as the pump body material and the diaphragm material of the diaphragm pump will not corrode and react with the medium used in the occasion, so as to avoid serious safety hazards.
16. Ensure that all operators at the site understand the safe operation and maintenance of the diaphragm pump and, if necessary, the necessary protective equipment.
Deposit Safe boxes are a good way to keep things safe, but they should be used in accordance with relevant regulations to avoid unnecessary risks. Choosing a safe that suits your needs can better ensure the safety and confidentiality of stored items.Deposit Safe is good in anti-drilling, anti-prying, anti-collision and anti-falling. integrated metal door panel is strong . pry-resistant shaped hinges, money box door won't lean forward, not easy to fall and well prevent against break-in after being locked.
