Definition and working principle

The pump system has a high-sensitivity pressure sensor mounted on the pipeline to detect pressure changes when there is a change in water consumption. The above signal is transmitted to the inverter to change the new frequency to the rotor speed controller. As a result, it is possible to add or remove pumping equipment in the system to stabilize the water pressure on the pipeline according to the requirements of users in the building.

The working diagram of the water pump system

Clean water supply system

The pressure sensor is located on the main water supply pipe. It will transmit a signal to the inverter when there is a change in pressure in the pipeline. At this time, the signal of inverter is compared with the preset pressure value. The inverter relies on the pickup comparison results to control the power supply frequency of the pump motor. The water level sensor should be placed in the tank. If the water level is too low for the pump to work, the sensor will signal to the inverter to stop the pump.

Sewerage system

Similar to the water supply system, the wastewater tank is also equipped with sensors that detect and control the level of sludge and the presence in the tank.

Classification of domestic water pumping systems for buildings

Understanding and choosing a water pump system carefully is extremely important. For buildings, two solutions are always the top priority: high-pressure water pumps and booster water pumps.

High push water pump

High push water pump is a type of machine capable of pushing water from the underground water source up through the energy source converted from electricity. High thrust water pumps have much higher capacity than conventional pumps.

The structure of high push water pump

High-pressure water pump is compact and convenient. Besides the main parts such as the motor and pump head, the machine also has a pump chamber cover, anti-friction pump disc with high heat resistance, thereby, helping the water flow stably. In addition, high thrust pumps are equipped with sensor relays. This part helps the machine automatically cut off the power when the temperature is too high, avoiding overheating, causing fire and explosion. Moreover, the machine also has a high-precision motor rotating core that is plated against rust to increase the durability and life of the machine.

Types of high push water pump

• High push water pump is a small-sized civil machine capable of pumping vacuum to a certain extent to pump clean water or other liquids, excluding corrosive chemicals. One of the features that distinguishes them from other types of pumps is the ability to absorb water and air, but the pump can still operate continuously.
• The semi-vacuum high-pressure pump is essentially a self-priming centrifugal pump. The machine has a large pump chamber structure capable of sucking up water mixed with air bubbles.
• Centrifugal pump is a type of pump that works on the principle of centrifugal force. The combination of flow, pressure, gravity frequency, and specific gravity of the fluid creates kinetic energy, which causes the water to move.

Booster water pump

Booster water pump is also known as booster water pump. This type of water pump has the function of increasing the water pressure automatically in the pipeline when the pressure decreases. The machine is capable of delivering a much larger volume of water than a conventional water pump in the same operating period.

Booster water pump

The structure of booster pump

The booster pump mainly consists of two main parts, the pump body and the pressure tank. Besides, the machine also has other auxiliary parts such as pressure switch, suction inlet, outlet, base and power cord.

Types of booster water pump

• The assembled booster pump is a pump that is fitted with a pressure tank and pressure relay system.
• The mechanical booster pump is a type of machine with a pressure tank and pressure relay without additional assembly.
• The electromagnetic booster pump is a fully automatic pump, using control by an electronic circuit board.
• Transformer booster pump is a series of machines that apply frequency-current technology to turn on off and automatically adjust the number of revolutions of the pump shaft to meet the needs of water use.

Standards for installation of domestic water pumping systems

• In the process of installing the water pump, it is necessary to pay attention to safety, avoid shaking when transporting and damaging the machine's parts. Filters can be installed at the front of the locomotive to ensure that there is no foreign matter affecting the switch wheel, clogging the motor.
• Minimize pipe folds, loops that reduce pump performance. At both ends of the pump, it is necessary to install a lock and a nozzle to facilitate the adjustment and repair process. The inlet and outlet pipes must be completely closed to avoid leakage, which may cause damage to the pump during operation.

With the goal of bringing the best quality service to customers, Taisei VN not only provides management - operation services, we also cooperate with other reputable units in ware pump maintenance for the building. When in-depth consultation and intervention is needed, Taisei VN will invite specialized units for each system to evaluate and offer the most suitable solutions. During the implementation process will be deployed under our close supervision to ensure your assets are safe.
