Support pipeline by blocking, jack stands or concrete saddles according to best piping practices. Don’t start pump while it is rotating in reverse direction after having just shut down the pump. It is advisable to install a time delay relay on electric drives to prevent this from happening. Non reverse protection in driver could also be a solution. Give a min time interval between starts, 5-10 min depending on the pump. Let pump come to a complete stop prior to starting again. Don’t put heavier than recommended heaters in the starter! These are protection devices for the pump, keep them as protection. If it keeps tripping something is the matter investigate further. Don’t add oil or grease to driver while running. Don’t add grease to grease lubricated driver without removing the relief plug. When working on a turbine, don’t drop parts into pump during the installation or disassembly. Don’t drop part into motor when canopy has been removed and top end is open. Parts must be removed before next operation clear your area prior to any starting. Don’t tighten shaft packing too tight!!! Tighten in increments, i.e., tighten gland nuts part of a turn and let pump run 5-10 minutes before tightening further. If leakage of water is too hot to put on your hand, back gland nuts off a little until water cools, then tighten again. Gland nuts need to be adjusted evenly so as to prevent cocking of the gland, forcing it against shaft. Recommended flow from the packing gland is a steady flow not spraying, more than a drip, less than a garden hose. Think flow not pressure. You want to clean and lubricate the shaft. Nice steady slow flow. Much like pouring water from a water bottle. Don’t start pump equipment with mechanical seals until air or vapor is vented from the seal housing. Housing should be filled with liquid to avoid damage to seal faces. Don’t forget that this equipment contains rotating parts. Use caution when working near such parts to avoid injury. Don’t neglect to replace all guards, covers and shields before start-up. Don’t run pump backwards. Correct rotation is counterclockwise viewing from top of the motor. Turning the pump backwards can unscrew shafts, cause power overloads to motor, and pull off impellers. These problems do not apply when pump is coasting backwards to a stop due to return flow of water from system. Don’t throttle the suction of the pump in a closed system. 0 Comments Add a Comment to this Post You must be logged in to post comments.
