The most common pumps used in air conditioning systems are centrifugal pumps. These pumps primarily consist of a pump impeller which connects to a motor’s shaft. The pump works by creating a differential pressure between water inlets and outlets enabling water to flow through the system’s pipes.
Increasing Pump Efficiency
The presence of air in your piping system reduces the efficiency of the pump. When installing your pump, it is wise to ensure air does not block the fluid flow. You can achieve this by giving the air an alternative path leading out of the system.
Early Detection of Pump Failures
There are four ways a pump can fail: a defective pump, poor maintenance, a lack of proper operating techniques and a poor application design. It’s okay to have a small leak at the seal of your pump. However, if the area surrounding your pump shaft floods suddenly, this is a sign a seal has failed and needs replacing. Excessive heat can also be an indicator of a failed bearing or motor.
Regularly checking your air conditioning pump will help identify these problems early.
Optimising Energy Use of Your Pumping System
Energy wastage in centrifugal pumps can be significant. Avoid pressure loss through the pipes by keeping bends that are not essential to a minimum. Using large pipe sizes for your design flow helps in minimising resistance. These tips will ensure your system optimises its operating energy consumption.
The centrifugal pump is the workhorse of modern HVAC systems. Proper maintenance and installation are cornerstones for efficient pump operation. Ensure you work with a qualified professional who will give you the best pumping system for your needs.
