Misunderstandings in the use of centrifugal water pumps
A high lift pump is used for low lift pumping
Many operators think that the lower the pumping head, the smaller the motor load. Under the misleading of this wrong understanding, when purchasing water pumps, the lift of water pumps is often selected very high. In fact, for centrifugal pumps, when the pump model is determined, the power consumption is directly proportional to the actual flow of the pump. The flow of the pump will decrease with the increase of the head, so the higher the head, the smaller the flow, and the smaller the power consumption. On the contrary, the lower the lift, the greater the flow, and the greater the power consumption. Therefore, to prevent motor overload, it is generally required that the actual pumping head of the water pump shall not be less than 60% of the rated head. Therefore, when the high head is used for low head pumping, the motor is easy to overload and heat, and the motor can be burned in serious cases. In case of emergency use, a gate valve for regulating the water output must be installed on the outlet pipe to reduce the flow and prevent overload of the motor.
Large diameter water pump with small water pipe
Many operators believe that this can improve the actual head. The actual head of the pump = total head - loss head. When the pump model is determined, the total head is certain; The loss head mainly comes from the pipeline resistance. The smaller the pipe diameter is, the greater the resistance is, so the greater the loss head is. Therefore, after reducing the pipe diameter, the actual head of the pump will not increase, but will decrease, resulting in a decline in pump efficiency. Similarly, when a small-diameter pump uses a large water pipe to pump water, the actual head of the pump will not be reduced, but the lost head will be reduced due to the reduction of the resistance of the pipeline so that the actual head will be increased.
When installing the water inlet pipeline, the horizontal section should be horizontal or upward
This will cause air to gather in the inlet pipe, reduce the vacuum degree of the water pipe and the water pump, reduce the suction head of the water pump and reduce the water output. The correct approach is: its horizontal section should be slightly inclined to the water source direction, should not be horizontal, let alone upward.
There are many elbows used on the water inlet pipeline
If more elbows are used on the inlet pipeline, local water flow resistance will be increased. And the elbow should turn in the vertical direction, and it is not allowed to turn in the horizontal direction, to avoid the accumulation of air.
The water inlet of the water pump is directly connected to the elbow
This will make the water flow unevenly distributed when entering the impeller through the elbow. When the diameter of the water inlet pipe is larger than the water inlet of the pump, an eccentric reducer shall be installed. The plane part of the eccentric reducer shall be installed on the top, and the inclined part shall be installed on the bottom. Otherwise, the air will be gathered, the water output will be reduced or the water cannot be pumped, and there will be impact sound, etc. If the diameter of the inlet pipe is equal to that of the water pump inlet, a straight pipe shall be added between the water pump inlet and the elbow, and the length of the straight pipe shall not be less than 2 ~ 3 times the diameter of the water pipe.
The bottom section of the water inlet pipe with the bottom valve is not vertical
If installed in this way, the valve cannot be closed by itself, resulting in water leakage. The correct installation method is: that the bottom section of the inlet pipe with the bottom valve should be vertical. If it cannot be installed vertically due to topographic conditions, the included angle between the water pipe axis and the horizontal plane should be more than 60 °.
The water inlet position of the water inlet pipe is incorrect
(1)The distance between the water inlet of the water inlet pipe and the bottom and wall of the water inlet pool is less than the diameter of the water inlet. If there is dirt such as sediment at the bottom of the pool, and the distance from the water inlet to the bottom of the pool is less than 1.5 times the diameter, it will cause poor water inflow or absorb sediment debris during pumping, blocking the water inlet.
(2)When the water inlet depth of the water inlet pipe is not enough, it will cause vortices on the water surface around the water inlet pipe, affect the water inlet and reduce the water output. The correct installation method is: the water inlet depth of medium and small water pumps shall not be less than 300-600mm, and that of large water pumps shall not be less than 600-1000mm.
The outlet pipe is above the normal water level of the outlet tank
If the water outlet is above the normal water level of the water outlet pool, the pump head is increased, but the flow is reduced. If the water outlet must be higher than the water level of the water outlet pool due to topographic conditions, elbows and short pipes should be installed at the nozzle to make the water pipe siphon and reduce the height of the water outlet.
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting, and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders, and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps i.e. pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables)
