Self-priming pump start using the operating procedures

2024-09-29 15:02:59
Start the self-priming pump, pay attention to the steering of the pump shaft is correct. Be aware of any abnormal sound and vibration when turning. Pay attention to the pressure gauge and vacuum gauge readings, after the start when the pressure gauge and vacuum gauge readings after a period of fluctuation indicating stability, indicating that the self-priming pump has been on the liquid, into the normal infusion operation. Self-priming pump into the normal infusion operation before self-absorption process, special attention should be paid to pump the water temperature rise, if this process is too long, the pump temperature is too high, then stop the pump to check the reason. If the self-priming pump liquid temperature is too high and cause self-absorption difficulties, you can temporarily shut down, the use of the discharge pipe back to the pump fluid back to the pump or the reservoir on the reservoir directly to the pump to replenish the liquid, so that the pump The liquid cooling, and then start. Self-priming pump in the course of work as a strong vibration and noise, there may be pump cavitation caused by cavitation have two reasons: First, the import pipe flow rate is too large, and second, the suction stroke is too high. When the flow rate is too large, the outlet control valve can be adjusted to increase the pressure gauge readings, which should be promptly removed when there is a blockage in the inlet pipe. When the suction stroke is too high, the installation height of the pump may be properly reduced. Self-priming pump in the course of work for some reason to stop the pump, need to start again, the outlet control valve should be slightly open (do not fully closed), so that both self-priming gas discharge from the spit, but also to ensure that the sharp tip Under the responsibility of starting. Pay attention to check the pipeline system for leakage. Self-priming pump parking precautions and operating sequence: 1, must first close the discharge valve on the pipeline. 2, stop the pump rotation. 3, in the cold season, should be stored in the body of the pump body and bearing body cooling water in the room to vent to prevent cracking parts.

Commercial And Household Glass

There are differences in commercial glass and home glass in multiple aspects:
1. Use
Commercial glass:
-It is mainly used for commercial buildings, such as office buildings, shopping malls, hotels, etc. Its functions often need to meet the specific needs of public spaces. For example, the glass window of large shopping malls requires good display effects and attract customers' attention.
-In some commercial places, such as banks, jewelry shops, etc., glass may need higher security, such as bulletproof and anti -theft.
Home Glass:
-In for family houses, such as windows, doors, furniture, etc. Pay more attention to meeting the needs of family life, such as providing lighting, protecting privacy, and decorating home furnishings. For example, the window glass of the bedroom may choose to have a shading function to ensure sleep quality.
2. Performance requirements
Commercial glass:
-The intensity requirements are high, and can withstand greater traffic and possible external forces. For example, the glass curtain wall of a commercial building needs to withstand the test of natural factors such as wind and rain, wind pressure.
-The optical performance may require higher transparency and uniformity to ensure the brightness and beauty of the business space.
-An sound insulation performance is also very important, especially in hotels, conference rooms and other places, need to reduce interference of external noise.
Home Glass:
-A safety is the key, especially for families with children and the elderly. Safe glass such as tempered glass may be selected to prevent serious damage to people when crushing.
-The insulation performance is also important, which can effectively reduce the energy consumption of the family. For example, double -layer hollow glass can play a better thermal insulation effect.
3. Design characteristics
Commercial glass:
-In large size, to meet the needs of large -scale lighting and open vision of commercial buildings. The design pays more attention to the coordination with the overall style of the building, reflecting the sense of modernity and fashion.
-It special coating technology, such as low -radiation coating glass to reduce energy consumption and ultraviolet radiation.
Home Glass:
-The design is more diverse, and you can choose different colors, patterns and textures according to the family decoration style. For example, art glass can add an artistic atmosphere to home.
-If attention to details and humanized design, such as easy cleaning, convenient installation, etc.
