Are there any regulations regarding the number of times the pump is started and stopped, or the duration of operation?

Refer to Article 4.0.6 of GB50170-2006 Code for Construction and Acceptance of Electrical Installations – Construction and Acceptance Specifications for Rotating Motors: \"The number of times an AC motor can be started under load shall comply with the provisions specified in the product’s technical specifications.\" ； When the product’s technical specifications do not provide specific requirements, the following rules may be followed: 1. It can be started 2 times in a cold state, with an interval of no less than 5 minutes between each start ； 2. It can be started 1 time while in the hot state. When dealing with an accident or when the motor startup time is no more than 2–3 seconds, it can be started again once. ” It should be useful for reference and understanding.
