Why Understanding Torque Is Vital For Pump Installation And Maintenance?
Posted in Uncategorised, on February 25, 2022 By Admin
A plethora of industries use a variety of pumps like liquid ring pumps, vacuum pumps and more for different purposes. There are also a lot of different factors that are taken into account while selecting a vacuum pump. One such criterion is torque, which can be defined as the force required to move an object on a rotational axis. Now, what is the contribution of torque while installing or repairing and maintaining a vacuum pump, or any other pump? This idea will be explored below in detail.
Role of torque in pump installation/maintenance.
Torque For Pump Installation
When looking to install a new pump for any application, it is vital to consider torque at zero flow, torque at rated flow and torque at maximum flow. Out of the three, the torque at zero flow is the most important criterion as pump inertia is highest when it is not operational. Hence, in order to get it working, the motor has to generate maximum torque. Now, to run such a motor, electricity is required, and therefore, a high amount of heat will be generated to initiate the process. Hence, both the pump and motor must be a good match in terms of size and operational capacity to function smoothly.
Torque For Pump Maintenance
A similar rule of thumb applies to maintaining a pump as well, as it’s key to keep the repairs to a minimum. So, for example, if a pump is operating at zero per cent speed, then in order to get it working, the load torque must at least be at twenty per cent. Once the pump speed increases, the load torque will automatically decrease as the two are inversely proportional to one another. Thus, it’s paramount to overcome the initial inertia and static friction, for any delay in torque generation will generate massive heat and potentially cause major repairs in the motor and pump system.
Hence, with a clear understanding of the importance of torque, manufacturers can make better choices while selecting a pump and motor set for their operation.
