Common faults of centrifugal pumps can be broadly classified into hydraulic faults and mechanical faults. In case of failure, it should be checked and eliminated in time, and the machine should not be "sick". The procedure for troubleshooting is: clarify the phenomenon - → analyze the cause - → to exclude. the reason: 1. The suction pipe is not deep enough to be inhaled in the pump; 2. Leakage and water leakage at the joint of the suction pipe; 3. There are water and grass debris in the suction pipe or impeller; 4. The water delivery height is too high; 5. Sealing packing leaks; 6. The water lift is too high; 7, the speed is not enough; 8. The suction pipe is suddenly blocked by debris; 9. It is entangled or damaged by inhaled debris; 10, the nozzle inhales a lot of air Method of exclusion: 1. Increase the length of the suction pipe, put a piece of wood on the water surface to prevent air from entering the water pipe 2. Tighten the connecting screws or replace the pads 3. Remove water and debris 4. Lower the water delivery height or close the gate valve on the small pressure water pipe 5. Tighten the gland or replace the packing 6. Adjust the suction head or close the small gate valve 7. Adjust the tightness of the drive belt. During the operation of the centrifugal pump, the pump suddenly stops discharging water. 8. Clear the blockage after shutdown 9. After shutdown, disassemble the pump, remove debris or replace the impeller 10. Deepen the depth of the suction pipe All in all, the cause of the pump failure is multi-faceted. For careful and meticulous analysis, do not be busy disassembling the parts. You should follow the principle of “external and post-internal†to find out the cause, “prescribe the right medicine†and eliminate the malfunction.
Testing Machine included PPF water Hydrophobic Testing Machine / PPF Pressure Inpact Testing machine and Steam Cleanner and more; Those testing machine mainly for TPU PPF to test the film water Hydrophobic, anti-scratch and self-healing features;
1)PPF water hydrogrobic testing machine is
The PPF water Hydrogrobic testing machine is a valuable tool for researchers, engineers, and scientists involved in the study and development of materials with hydrogrobic properties. It helps in the evaluation and selection of materials for specific applications, ensuring their durability and performance in water-related environments.
2) PPF (Pressure Impact Testing) machine is a device used to test the impact resistance of materials and products. It is commonly used in industries such as automotive the durability and safety of various components.
The data obtained from PPF testing can be used to optimize material selection, design, and manufacturing processes, ensuring that products meet the required safety standards and performance criteria. It helps manufacturers identify potential weaknesses or vulnerabilities in their products and make necessary improvements to enhance their durability and reliability.
3)Steam cleanning machine is the smart high pressure cleanning machine,which uses steam to remove dirt, grime, and stains from various surfaces. It is commonly used on car interior or home house carpets, upholstery, and hard floors. Steam cleaning is a method of cleaning that uses high-temperature steam to remove dirt, stains, and bacteria from various surfaces. It is commonly used on carpets, upholstery, tiles, and grout.
These machines heat water to a high temperature and then release the steam through a nozzle or brush attachment. The steam is applied to the surface being cleaned, and then dirt and grime are loosened and lifted away.

When the centrifugal pump is running, the water output of the pump is insufficient.
Overall, the PPF Pressure Impact Testing machine is a valuable tool for quality control and product development, enabling manufacturers to produce safer and more durable materials for TPU PPF car wrapping film.
Steam cleaning is effective because the heat of the steam can kill bacteria, germs, and dust mites, making it a popular choice for those with allergies or asthma. It is also a chemical-free cleaning method, as the steam itself is enough to clean and sanitize surfaces.
Overall, steam cleaning is a versatile and efficient method of cleaning that can be used on a variety of surfaces. It is an eco-friendly option that provides a deep and thorough clean.
