Selection Tips
Flow rate
This is generally the effectiveness of the water pump. Flow rate refers to the time taken by a water pump to pump a specific amount of water mostly measured in liters per minute. If you are going to use the water pump for either job sites or farms, you should purchase one that has the ability to pump over 2500 liters of water per minute. On the other hand, a pump with a flow rate of between 100 – 200 liters per minute is suitable for any home use.
The size of the inlet
Most pumps have an inlet size of between 1 to 6 inches but in some cases, it can be more. Centrifugal water pumps also operate in a similar way i.e. sucking in water from the inlet and discharging it through the outlet valve. In that case, the bigger the size of an inlet valve, the more amount of water the pump will be able to pump out and the faster it will do the job.
Maximum head and pressure
The maximum head of a water pump refers to the longest distance in terms of height that the pump will be able to pump water. For instance, if you buy a water pump with a maximum head of 60 meters, if you try to pump water to levels higher than that then the flow rate will be zero. Generally, the type of pump you choose should have a maximum head higher than the height you intend to pump the water.
The quality of the pump
The first thing to consider is the brand of the water pump. The engine or the motor can also tell you the quality of the pump. Conduct the necessary research and surveys on how the quality of a water pump should be.
The type of water to be pumped
The type of water you are going to pump is also a factor to consider. Transfer pumps are different from firefighting pumps. Other types of pumps include chemical pumps and trash pumps.
How to use the water pump correctly?
After purchasing all kinds of pumps, it is easy to damage the pumps if the knowledge about how to use the pumps is insufficient. Therefore, it is necessary to understand and master the knowledge of how to use the pumps correctly.
When using the water pump, after connecting the power supply, carefully observe the operation of the water pump. The water outlet should be continuous and uniform, and the water pump can be used only when there is no vibration and noise. In case of a sudden shutdown during operation, immediately disconnect the power supply and check the cause. The interval between the two starts of the pump shall be limited to the return of all the water in the pump. If it is started too early, the motor will be burned due to excessive resistance and a water hammer in the water pipe. In addition, if the water pump is installed in the well, it should be noted that the flow of the water pump should conform to the normal water output of the well, otherwise it will cause the empty machine to run and burn the motor.
Precautions for installation and use of water pump
- Before the operation of the sewage pump, use a megger to check the insulation resistance of the motor stator winding to the ground, which shall not be less than 50 megohms at least.
- Check whether the submersible pump cable is damaged or broken. In case of damage, it shall be replaced in time to avoid electric leakage; The cable section should match the current.
- When the voltage of the water pump exceeds ± 10% of the rated voltage, the water pump shall not be started.
- To ensure the safety of use, the grounding wire in the four-core cable must be reliably grounded to prevent electric shock accidents.
- When diving into the water, the submersible sewage pump should be lifted vertically, and it is not allowed to be placed horizontally, let alone trapped in the sludge. When stopping using, lift the electric pump, clean it, put it in a dry place, and pay attention to antifreeze.
- It is forbidden to use the cable as a lifting rope for installation.
- Check the running direction of the rotor. It should rotate clockwise from top to bottom.
- Rainproof and moisture-proof measures shall be taken for outdoor switches or terminals. It is forbidden to touch the switch when wet hands or bare feet to prevent electric shock.
- When moving the sewage pump, the power supply must be cut off, and people are not allowed to contact the water source when the electric pump is running, to prevent personal accidents caused by electric leakage.
- It is strictly forbidden to operate the motor in phase failure. If the fuse is found to be blown, it can be used only after checking the cause. It is not allowed to thicken the fuse arbitrarily.
- The water pump shall be managed by specially assigned personnel during operation. In case of any abnormal phenomenon, it shall be shut down immediately for inspection and troubleshooting.
- After the water pump operates normally for half a year under the specified working medium conditions, the sealing condition of the oil chamber should be checked. If the oil in the oil chamber is milky or there is water precipitation, the 10 ~ 20 mechanical oil and mechanical seal should be replaced in time. The electric pump used under bad working conditions should be overhauled frequently.
- The user should choose the appropriate flow head according to the actual working conditions to achieve the use effect. The parameters shown on the nameplate or manual of the water pump are the working conditions. The user can choose to use it within (0.7 ~ 1.2) times the flow. It is forbidden to use it with the excessive flow, otherwise, the flow is too large and the lift is too low, which will easily overload the motor.
Application field
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. pumps driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables) and a starting protection de
