Selection Guide for Pumps of Reel Irrigation Machines: Centrifugal Pumps and Submersible Pumps
In the field of agricultural irrigation, the efficient operation of reel - type irrigation machines relies on the support of suitable pumps. For hose reel irrigation equipment, there is a wide variety of pump types available, including centrifugal pumps, submersible pumps, self - priming pumps, mixed - flow pumps, and axial - flow pumps. This article will focus on centrifugal pumps and submersible pumps, delving deep into their working principles, characteristics, and how to select them according to different irrigation conditions. Easton Irrigation Machinery Company, a well - known enterprise in the industry, offers a variety of high - quality pump products that are suitable for hose reel irrigators.
Centrifugal Pumps: Working Principle and Characteristics
The working principle of a centrifugal pump is based on the centrifugal force generated by the rotation of the impeller. When the impeller rotates at high speed, the water inside the pump body is thrown towards the outer edge of the impeller under the action of centrifugal force, enabling the water to gain energy and achieve efficient water transportation. This working mode endows centrifugal pumps with many remarkable advantages.
It has a relatively simple structure, which not only reduces manufacturing and maintenance costs but also improves operational stability. Centrifugal pumps have a wide range of flow rates and heads, and can flexibly meet the needs of different - scale reel - type sprinkler irrigation machines. For small - area irrigation reel - type sprinkler irrigation machines, small - sized centrifugal pumps can play an excellent role; while in the application scenarios of large - scale reel - type sprinkler irrigation machines for large - area irrigation, large - sized centrifugal pumps can demonstrate their powerful water supply capabilities. For example, the centrifugal pump products of Easton Irrigation Company are highly favored in the market for their reliable performance.
Submersible Electric Pumps: Unique Working Mode and Application Advantages
The working mode of submersible electric pumps is rather unique. The motor and the pump are directly connected into a compact whole and can work directly when submerged in water, easily lifting water from low - lying areas to higher places. This structural design gives submersible electric pumps some incomparable characteristics.
Submersible electric pumps have a compact structure and are easy to install, and are suitable for various water sources such as deep wells, canals, and reservoirs. When encountering situations where the water source level is low, submersible electric pumps become the first choice. They can efficiently extract deep - layer water and stably supply water to reel - type sprinkler irrigation machines. In cases where the well water depth exceeds 10 meters and the water level is sufficient, or when the reservoir is severely clogged, submersible electric pumps demonstrate excellent applicability due to their characteristic of being directly installed in the well.
Precise Pump Selection Based on Water Source Conditions
The water source conditions are the key factors determining whether to choose a centrifugal pump or a submersible pump. If the water source is a river, lake, reservoir, etc., and water needs to be pumped from the ground, or the well water depth is within 10 meters, or there is a large terrain drop in the irrigation area, and water needs to be transported to a far - away place, a high - head pump is the ideal choice. The Easton company’s 32 horsepower centrifugal pump set is an excellent solution for such scenarios. This centrifugal pump set is ingeniously combined with a well - known brand diesel engine and a single - stage high - pressure centrifugal pump. The maximum flow rate of the pump can reach 180 m3/h, the maximum head reaches 100 meters, the suction lift is between 9 - 10 meters, and the matching power is between 22 - 30KW. It can perfectly drive the JP75 series and JP90 series hose reel sprinkler irrigation machines produced by the company.
Conversely, if it is well water with sufficient water level and a depth exceeding 10 meters, or the reservoir is severely clogged, submersible pumps are more suitable. Their characteristic of being directly installed in the well can effectively cope with such complex water source conditions.
Key Points of Pump Maintenance and Upkeep
To ensure the long - term stable operation of the pump, regular maintenance and upkeep are of utmost importance. First, regularly check all components of the pump to ensure their normal operation and promptly detect and address any wear or blockage issues. Second, regularly clean the inlet and outlet of the pump to prevent impurities from entering, as even tiny impurities can have an adverse impact on the pump's performance. Finally, regularly replace worn - out seals and bearings, which is a crucial step in maintaining the efficient operation and extending the service life of the pump.
Centrifugal pumps and submersible pumps each have their unique application scenarios in agricultural irrigation. Easton Machinery Company, with its rich product line and excellent product quality, provides users with diverse choices. When choosing a pump, users must fully consider their own environmental conditions and make the most appropriate decision to achieve the efficient operation of the reel irrigation machine and the best effect of agricultural irrigation.
