1. Working principle of household well water pump
Well water pump is the core equipment that extracts groundwater to the ground and transports it to the household pipeline system. The working process can be divided into several main steps:
1.1 Pumping principle
The well water pump generates negative pressure through one or more mechanical devices, forcing groundwater to flow out of the well. For submersible pumps installed inside the well, their working principle is to directly use a motor to drive the impeller to rotate, pushing water out of the well; The jet pump installed on the ground utilizes pneumatic principles to create negative pressure and attract water into the pump body, which is then pressurized and transported to a predetermined location.
1.2 Pressure water delivery
After pumping, the impeller or piston inside the water pump will pressurize the water. The pressurized water is transported to the pressure tank through pipelines to further regulate the water pressure, so that the water flow reaches a stable state and is redistributed to various water points (such as kitchens, bathrooms, gardens, etc.). This process ensures the continuity and balance of household water supply.
1.3 Function of key components
Inlet pipe and filter: prevent sediment and impurities from entering the pump body, ensuring long-term stable operation of the equipment.
Motor and impeller: The motor provides energy to drive the impeller, which is the key to generating water flow and pressure.
Sealing device: prevents water leakage and ensures efficient operation of the equipment.
The above principles and components together constitute the core working mechanism of well water pumps, and are also the foundation for ensuring the safety and efficiency of household water supply.
2. Types and applicable scenarios of household well water pumps
According to the depth of the well, water demand, and installation environment, well water pumps can be classified into various types. Below are several main types of well water pumps and their applicable scope:
Jet pumps are generally installed on the ground, and the well water is sucked into the pump body through a suction pipe for pressurization.
Applicable scenario: Household well water systems with shallow well depths (usually less than 25 feet/about 7.6 meters).
Working principle: Utilize the kinetic energy and suction generated by water jet to make water rise along the suction pipe.
Advantages: Easy installation, convenient maintenance, suitable for daily household water needs.
Disadvantages: When the well depth exceeds a certain range, the efficiency will significantly decrease, and there is a high requirement for the sealing of the suction tube.
The submersible pump is installed inside the well and fully immersed in water. Its working principle is to directly "push" the water out of the well.
Applicable scenarios: Suitable for medium to deep wells or deep wells (with depths exceeding 25 feet, some models can adapt to depths up to 400 feet or more).
Working principle: The motor works in water, directly pushing water from the bottom of the well to the surface with high efficiency.
Advantages: low operating noise, low energy consumption, stable pressurization effect; Adapt to deep well water supply.
Disadvantages: Professional skills are required during installation, and maintenance costs are high. Once a malfunction occurs, it may need to be replaced as a whole.
2.3 Deep Well Jet Pump
Deep well jet pump is between jet pump and submersible pump, which can adapt to deeper wells and can be installed on the ground. It mainly extracts water through pipeline system.
Applicable scenario: Suitable for well water systems with depths between 25 and 100 feet.
Advantages: The design is flexible, easy to maintain, and can balance efficiency and installation costs.
Disadvantages: The performance may not be as good as submersible pumps, and there are higher requirements for the sealing and design of wellhead pipelines.
2.4 Manual pump
Manual pumps are mainly used for emergency water supply or short-term water supply in environments without electricity.
Applicable scenarios: wilderness camping, sudden power outages, or environments with low water demand.
Advantages: Simple structure, easy to use, no need for power supply.
Disadvantages: High physical exertion, low pumping efficiency, not suitable for long-term household water supply systems.
Through the introduction of different types of well water pumps above, consumers can choose the most suitable product based on actual well depth, water demand, and budget, ensuring the long-term stable operation of the well water system.
3. Composition and working mechanism of household pressure system
The pressure system plays a key role in regulating water pressure and stabilizing water flow in household well water pumps. Common pressure systems mainly consist of pressure tanks, pressure switches, check valves, and pressure regulating valves. The following will analyze the functions and working principles of these key components one by one:
3.1 Pressure Tank
Pressure tank is the most important water storage and pressure regulating equipment in well water systems.
Main function: Store a certain amount of pressurized water when the water pump stops working, and maintain the water pressure within the set range through compressed air or diaphragm, thereby reducing frequent pump starts and extending equipment life.
Type:
Bladder type pressure tank: Equipped with a rubber bladder, it can effectively isolate water and air, preventing air from entering the system.
Diaphragm pressure tank: using metal or composite material diaphragm, with high durability and stability.
Traditional air pressure tanks: water and air are directly mixed, making maintenance more complex, and are now commonly used in old systems.
3.2 Pressure Switch
The pressure switch is responsible for monitoring the system water pressure and controlling the start and stop of the water pump according to the set value.
Working principle: When the system water pressure drops to the preset lower limit (such as 30 PSI), the pressure switch will automatically start the water pump; When the water pressure reaches its upper limit (such as 50 or 60 PSI), the water pump will stop running.
Importance: Accurate pressure switches not only ensure that the water pump operates at its optimal state, but also prevent damage to pipelines and equipment caused by excessive water pressure fluctuations.
3.3 Check Valve and Pressure Regulator
Check valve: installed at the outlet of the water pump to prevent pressurized water from flowing back into the pump body, thereby protecting the pump body from backflow damage.
Pressure regulating valve: regulates the water pressure entering the household water supply pipeline, ensuring that the water pressure at each outlet point is balanced and preventing damage to equipment and pipelines due to high water pressure.
3.4 Overall workflow of the system
Start up phase: When household water usage causes a decrease in system water pressure, the pressure switch triggers the water pump to start and extract water from the well.
Pressurized storage: The extracted water enters the pressure tank and maintains a constant pressure through the action of internal air or diaphragm.
Water supply stage: Stable pressurized water is distributed to various water consuming equipment through pipelines, while check valves and regulating valves ensure safety and stability during the water supply process.
Stop phase: When the pressure reaches the set upper limit, the pressure switch automatically shuts off the water pump, and the system enters standby mode until the next water demand.
The efficient collaboration of this entire system not only ensures the continuity and stability of household water supply, but also significantly extends the service life of pumps and related equipment during long-term operation, while improving energy efficiency and safety.
