Correct choice of submersible pump two steps

Submersible pump is an important equipment for deep well water supply, has been widely used in domestic water, mining rescue, industrial cooling, farm irrigation, sea water lifting, transfer of ships, can also be used for water works such as fountain landscape In a wide range of uses. However, many consumers at the time of purchase due to the lack of guidance of professional and technical personnel, a direct result of loss of production and waste of cost, and some safety accidents will occur, affecting submersible pump life. This shows that the purchase of a safe and durable submersible pump is very important. So in the end it now buy it, the following small inventory for everyone inventory Weapon, two steps to teach you the correct choice of submersible pumps. The correct choice of submersible pump two steps First, when you want to see the brand and product quality certification A standard, qualified pump is manufactured according to ISO requirements, long life, low energy consumption. When the purchase to agricultural machinery sector approved point of sale, recognize the manufacturer, see the grades and product quality certification. Can not buy no manufacturers, no production date, no production license of the three non-products, or in case of problems is difficult to solve. New customers, you can consult the experts in the pump, you can also consult directly with their own use of similar old users, so you can avoid detours. Second, to clarify the relationship between the pump head and pump flow Pump lift does not mean that the height of the water, a clear choice of pump is particularly important. Pump lift about 1.15-1.20 times the height of the water. For example, a water source to the water at a vertical height of 20 meters, its required lift is about 23 to 24 meters. Therefore, the choice of pump, the pump nameplate lift on the best and the actual required close to the head, so that the most efficient pump, the use of more economical. However, it is not required that the lift on the nameplate of the pump should be absolutely equal to the actual required lift. Generally, the deviation should not exceed 20% and the pump can work under more energy-efficient conditions. Submersible pump head and outlet flow is also a matter of exquisite. High-lift pump for low lift, there will be flow is too large, motor overload phenomenon, if the long run, the motor temperature increases, the winding insulation will accelerate aging, or even burn the motor. If the pump head is far less than the actual lift required, often can not meet the user's wishes, even if it can pump water, the water will be small. Therefore, the choice of water pump out of the water flow generally not too large election, otherwise it will increase the cost of purchasing a pump. Specific issues should be specific analysis, such as user-owned draft self-priming pump, the flow should be selected smaller; if the submersible pump for irrigation, you can choose the appropriate flow larger. The above is the correct way to buy submersible pumps, the main is to see the brand and clarify the pump head and flow, I hope these methods can help you.
