How to Increase Submersible Pump Efficiency? (Tips by Experts)
Pumps are the core of any system that handles fluids. In the general industry, pumps are the second most common piece of machinery used. A mechanical force known as a Pump helps to move fluids, gases, liquids, and slurries from one location to another by a hydraulic passage. When designed with utmost efficiency, this mechanical system becomes a boon to the industry. If one desires to keep an edge over the competition, parasitic losses in any mechanical system should be lessened.
What is Pump efficiency?
It is to be noted that before purchasing a Submersible Pump Efficiency pump, its efficiency should be importantly determined. A correct pump will conserve fuel electricity and decrease downtime and maintenance costs. The ratio of the water horsepower provided by a pump to the brake horsepower given to the pump shaft is known as pump efficiency. One of the most important considerations when choosing a pump is pumping efficiency. The flow required, the height lifted, and the length and friction characteristics of the pipeline all influence the amount of energy used in a pumping plant. A pump’s efficiency is referred to by how well it can convert from one form of energy to another. The productivity of a machine is 50% if one unit of energy is provided and the output is one-half unit in the same units of measure.
How is Pump efficiency attained?
Pump efficiency is attained by these three discrete competencies- mechanical, volumetric, and hydraulic. Losses in bearing frame, stuffing box, and mechanical seals are included in mechanical efficiency while losses due to leakage through the wear rings, balancing holes, and vane clearances in the case of semi-impellers are included in volumetric efficiency. The liquid friction and other losses in volute and impellers are included in hydraulic efficiency. Hydraulic efficiency is considered the largest factor while mechanical and volumetric loss is important components.
Tips to Increase Performance
1. Operate your Pump at BEP
The flow at which your pump is operating at its optimum efficiency for its impeller diameter is considered as the best efficiency point or BEP. The axial and radial loading is reduced to the lowest possible value at the BEP. If the flow in the pump is too low, then the velocity will end up being low in moving through systems. Resultantly, it will have a drop on solids in the fluid and they will further settle in the piping system, leading to clogging. On the other hand, if there is too much velocity then the flow will end up moving too fast, leading to the shredding of Submersible Pump Efficiency solids and clogs. In these cases, a throttling valve or orifice plate is found helpful.
2. Pump Cycle Minimization
When the discharge rate and the influent rate is balanced, it helps in minimizing the number of pump starts. The rate at which the water comes into the pump is referred to as the influent rate. The amount inflow of the pump is referred to as the discharge rate. If you have a little wet well, you will have to fill it up and drain it regularly. This leads to the short cycling of the pump every minute or two, leading to overheating Submersible Pump Efficiency or failure in the motor. In fewer cycles the motor is cooled, making the pump run smoothly.
3. Matching Pump Size to the Pipe Size
A velocity of approximately seven feet per second is required in wastewater systems with more solids and flushable wipes, this prevents solids from settling and plugging the system. For slurries and heavier solids, higher velocity is required. The velocity is impacted by the pipe size. To prevent solids from clogging, higher velocity is required in oversized pipes. The head to the system increases in undersized pipes that increase friction and reduce the flow on the other hand. Hence, it is necessary to ensure that the pump size matches the pipe size.
To improve the efficiency of fluid handling systems and to protect metals from getting affected by corrosion and erosion, coatings are designed specially. For lining hydraulic passages in the pump, Submersible Pump Efficiency their combination such as hydrophobicity, self-leveling, and hydraulic smoothness makes these coatings ideal candidates. The hydraulic smoothness and slipperiness of the pump passage is increased when the efficiency-improving coating is applied. A small percentage of Teflon can enrich it which contributes to a reduction in frictional forces between surfaces and fluid in motion.
