The process operating temperature of the unit has changed.A pump and drive unit are initially installed (before grouting the baseplate, after grouting the baseplate, after connecting the piping, and after the first run).Reduced parts expense and lower inventory requirementsįurther, in order to insure good alignment, the alignment must be checked and correctly set when:.Increased productivity through time savings and repair avoidance.Lower energy losses due to friction and vibration.Good alignment has been demonstrated to lead to: Indeed, using precise alignment methods is one of the principal attributes of a reliability focused organization. Performing precise alignment, therefore, pays back through preventing the costly consequences of poor alignment. The inevitable result is premature failure of shaft seals and bearings. Even small pumps can generate big losses when shaft misalignment imposes reaction forces on shafts, even if the flexible coupling suffers no immediate damage. Misaligned pumps can even consume up to 15% more energy input than well-aligned pumps. Learn more about MWI’s customizable line of submersible electric pumps here.Experience shows that many pump distress events (failures) have their root cause in the misalignment of the pump to motor. That way, when your pumps do need part replacements, you won’t be paying a premium for a quick fix. Look for pumps that use non-proprietary bearings and seals. If your pump isn’t working, it could require more than a quick fix. Their simple design also means that they are easy to maintain. They push water to the surface, and they’re more efficient than ground-level pumps.
The value of submersible pumps is that they have sealed motors that are close-coupled to the pump body. Cavitation may also be caused by the characteristics of the water itself, and it may be necessary to adjust the pump to compensate for viscosity.
SUBMERGE PUMP DRIVER
Check the alignment between the driver and pump. The noise is accompanied by a loss of pump efficiency. Your pump is causing or reacting to bubbles that are formed in the water being moved. This may be something as easy to fix as checking all the valves in line to the pump. An insufficient water flow might indicate that your pump isn’t fully submerged, or that your lift requirement is too high. Proper placement is necessary for optimal pumping operation. A sight inspection can give you the answer. Or, it might be bound by something that’s been caught in the impeller. If neither of those are the cause, your pump may simply be air bound. Your check valve may have failed, or it’s been installed incorrectly. Not enough water is running through the pump system Check the line terminals to determine if this is the source of the problem. If you’re on a construction site and using temporary power, your pump might be drawing incorrect voltage. The overload protector keeps trippingĭo you have the overload protectors in direct sunlight? That’s enough heat to cause them to trip. Double-check the settings, and clean the contacts.Ī motor that never shuts off can also indicate that your pump screen is blocked or that your check valve is stuck. Replace any leaking or damaged pipes and check the water level to make sure that your pump hasn’t exceeded the well capacity.Ī faulty pressure switch will also cause the motor stay on or cycle too fast. The motor runs continuously or too oftenĪ leak in your system will cause both of these issues. You’ll get amp readings up to six times higher than normal before the safety overload trips. Look to see if there’s anything bounding the pump. Debris or corrosion can cause irregular voltage. Next, check the voltage at the contact points for the pressure switch. If the problem is intermittent, it could be dirty or corroded fuse receptacles. Check for blown fuses or a tripped circuit breaker. Use this troubleshooting guide to see if there’s a quick fix for what’s ailing your submersible pump. And if something does go wrong, their configuration makes it easy to repair and maintain them. Submersible electric pumps are true workhorses that perform well for flood control and storm-water drainage. You can configure them for vertical or horizontal use, or any angle in between. There could be a very easy solution to that pump’s problem.
