Variable frequency water supply equipment for daily life

Variable frequency water supply equipment for daily lifeIt is a commonly used water supply equipment in household life, which mainly drives the water pump through an electric motor and uses variable frequency speed regulation technology to achieve constant water pressure supply. The constant pressure variable frequency water supply equipment for daily life has the advantages of constant water pressure, energy conservation and environmental protection, silent operation, and space saving, and is widely used in fields such as household life, commercial buildings, farmland irrigation, and industrial production. It is of great significance for improving water resource utilization efficiency, enhancing user experience, and ensuring production demand.

1、 Advantages of Variable Frequency Water Supply Equipment for Daily Life

1Constant water pressure: The constant pressure variable frequency water supply equipment for daily life can achieve constant water pressure supply, which is not affected by changes in water pressure inside and outside the water supply network. Regardless of the amount of water used in the household, a stable water pressure can be maintained, allowing users to enjoy a comfortable water flow experience during bathing, laundry, flushing and other domestic water use processes.

2Energy saving and environmental protection: The household constant pressure variable frequency water supply equipment using variable frequency speed regulation technology can intelligently adjust the speed of the motor according to actual needs, reducing energy consumption. Compared to traditional constant speed water supply equipment, the energy-saving effect is significant. At the same time, due to the ability to control the operating status of the water pump, frequent start stop of the water pump is reduced, equipment wear is also reduced, and the service life is extended.

3Silent operation: The constant pressure variable frequency water supply equipment for daily life uses an electric motor to drive the water pump, which is quieter compared to traditional gas pumps or diesel pumps that use internal combustion engines to drive the water supply equipment. Users will not be disturbed by noise in their home life, providing a quieter and more comfortable living environment.

4Space saving: Constant pressure variable frequency water supply equipment for daily life is usually designed with a box structure, integrating various components such as motors, frequency converters, controllers, etc., occupying a small space. This makes the installation and placement of equipment more convenient and flexible, especially suitable for use in new houses and small households.

2、 Application scope of household variable frequency water supply equipment

1Family life: Constant pressure variable frequency water supply equipment can be applied to the supply of tap water in family life, meeting various daily water needs such as bathing, laundry, and flushing. Whether it is high-rise residential buildings, villas, apartments and other different types of houses, they can provide stable water pressure and improve the quality of life.

2Commercial buildings: Constant pressure variable frequency water supply equipment is also widely used in commercial buildings, such as office buildings, shopping centers, hotels, etc. Provide constant water pressure in commercial areas such as toilets, restrooms, and bathrooms to meet users' water needs.

3Irrigation of farmland: Constant pressure variable frequency water supply equipment can be used in farmland irrigation systems to provide constant water pressure and flow rate, ensuring the normal growth and irrigation effect of crops. Especially suitable for areas with unstable water pressure such as slopes and hills.

4Industrial production: In some industrial production processes, constant water pressure is required to meet the water demand of production equipment. The constant pressure variable frequency water supply equipment for daily life can be applied to the water supply system in industrial production, providing reliable water pressure support to ensure smooth production.

3、 Fully automatic non negative pressure variable frequency water supply equipment

The fully automatic non negative pressure variable frequency water supply equipment refers to the non negative pressure stacked water supply equipment that is directly connected in series to the water supply pipeline during operation. The control system continuously monitors the pressure of the tap water network and the water supply network. When the incoming water pressure is lower than the user's required pressure, the variable frequency device automatically controls the speed of the water pump according to the amount of water used, and balances the water flow through a steady flow compensator to maintain constant pressure water supply.

In a multi pump system, the control system automatically schedules the water pumps based on the amount of water used, which can balance the working time of the water pumps and ensure the water supply pressure. When the incoming water pressure meets the user's required pressure, the system automatically stops the pump and switches to direct water supply from the external pipeline network. When using water, if the water supply from the tap water network is less than the user's required amount, the water pump will automatically slow down and reduce the pressure for water supply. The water in the steady flow compensator can be used as a supplementary water source to maintain short-term water supply. At this time, the vacuum suppressor acts to ensure that the tap water network does not generate negative pressure. When the water level in the compensator is below the limit value, the system will automatically protect and stop the pump, and the water supply will be directly from the external pipe network.

After the situation, the system returned to normal water supply status. Non negative pressure refers to the energy-saving and pollution-free water supply method in which the water supply equipment can eliminate the suction stroke generated by the water pump during operation through the control mode of the equipment, the joint action of the steady flow compensator and the vacuum suppressor, without affecting the dynamic pressure of the tap water network. It also utilizes the pressure of the original tap water to compensate for the pressure difference.

4、 Characteristics of Non negative Pressure Variable Frequency Water Supply Equipment

1Without the need for water tanks or pools, water can be supplied directly through the pipeline network to prevent secondary pollution of water quality.

2Adopting advanced intelligent frequency conversion control technology, automatic voltage compensation.

3Anti negative pressure automatic control system.

4Automatic shutdown when water is cut off, and automatic startup when water is supplied.

5When the natural pressure of the pipeline meets the water demand, it automatically enters standby mode.
