There are many different types of motors that used across a wide range of industries. Some of them are specific to certain tasks, while others care for a wide variety of needs. In the agricultural industry, one of the common types of motors used is the hollow shaft irrigation motor. It solves an issue often seen in agriculture, the need to water crops when the reservoirs are not adequate.
For many years, people used groundwater to water their crops. They used horizontal pumps above ground to pull the water up to the surface. The problem was there were high operating costs involved, and the equipment was often under considerable strain. These issues added to the cost and possible downtime. The solution came in the form of a vertical pump motor, which first developed in 1922. This revolutionary motor made it possible to irrigate larger areas. Even when the water was in short supply in those areas.
There were many resolutions for these issues as a result of the vertical hollow shaft irrigation motor. These are still issues that are worthy of consideration today.
Costs: Vertical pump motors operate at a high efficient level. The vertical pumps move more water without the high operating expenses of a horizontal motor.
Convenience: The combination of a vertical pump and vertical motor eliminated the need for a mechanical gearbox. Because there is less equipment involved in the vertical pump, it is easier to install and has a much smaller footprint. Another factor to consider is the possibility for vibration. Since the motor shafts align easier with the vertical motor, there is less of a chance for vibration. As a result, there is an extension of the operating life of the motor.
Durability: The design for vertical motors is specific for pumping water from the ground. They are more reliable and durable than horizontal motors.
Two Types of Vertical Shaft Motors
It is necessary to make a choice between the two types of vertical pump motors; a solid shaft or hollow shaft. With a hollow shaft motor, the head shaft of the pump can extend through the motor and connect to the coupling. With a solid shaft motor, the pump shaft is coupled to the solid shaft by an external coupling.
Although there are considerations for both types of motors, the motor that is advantageous for most uses is the hollow shaft motor. There are fewer parts, so there is less cost involved. Plus, there is easier access to the top of the motor and the adjusting nut. Hollow shaft motors are also less likely to experience problems with vibration.
