High-rise building water supply equipment | non-negative pressure water supply equipment | secondary pressure pump

Equipment introduction: The non-negative pressure boosted water supply equipment uses a water pump to be directly connected to the tap water pipe network, uses a pressure regulating tank as the pump water inlet and water storage device, and uses a vacuum eliminator to eliminate the negative pressure generated in the pipe network, making full use of the tap water pipes. It achieves secondary pressurization of water supply based on the original pressure of the network. This equipment not only achieves the purpose of pressurization (and does not affect the water pressure of other users of the pipe network at all), but also saves the investment in building pools and water tanks, while ensuring the pipe While improving the water quality of the network (no secondary pollution), it can also make full use of the original water pressure of the pipe network, and its energy saving effect is extremely significant, reaching more than %. The non-negative pressure water supply equipment is fully automatic and intelligently controlled. It has a variety of protection and control functions and can be truly unattended.
Scope of application:
Domestic water for residents such as high-rise buildings, residential areas, villas, etc.
Daily water use in enterprises, institutions, hotels, office buildings, department stores, large saunas, hospitals, schools, gymnasiums, golf courses, airports and other places.
Production and manufacturing of washing equipment for production water in food industry factory conditions.
Others: transformation of old pool water supply and other forms of water supply.
Equipment features:
Saving investment
Saving investment by about %, no need to build a reservoir or roof water tank, using superimposed water supply, reducing initial investment in equipment.
High efficiency and energy saving, low operating cost
It can make full use of the water supply pressure of the municipal pipe network, and can make up for the difference without generating negative pressure. Compared with traditional water supply equipment, it can save energy by %%. Even in the event of a power outage, water pressure and water supply from the municipal pipe network can be maintained.
High degree of intelligence, simple operation, saving manpower
The equipment is controlled by a fully automatic intelligent controller, which can adjust itself according to the user's water consumption and the tap water pressure of the pipe network, achieving unattended and adopted The human-machine interface (text and number) display allows customers to see the operating status of the equipment more intuitively.
Environmental protection and sanitation
The equipment is fully enclosed and operates to completely eliminate secondary pollution of water sources.
Complete protection functions
It has reliable automatic protection functions such as overload, short circuit, over voltage, under voltage, phase loss, over current, short circuit, water source and water shortage. Under abnormal circumstances, signal alarms, self-tests, fault judgments, etc. can be carried out.
Small footprint and easy installation:
The whole set of equipment only consists of one set of water supply control cabinets, no negative pressure stabilizing tank and water pump unit, and the installation is very simple.
Extend the service life of the equipment:
It can reliably realize soft start for multiple pump units, so that the power grid and pipe network are protected from impact, and they can run in turns, greatly extending the service life of water pumps and motors. Extend the life of equipment by more than twice.
Ordering Notes:
Equipment material (standard configuration is stainless steel, if there are other material requirements, please declare in advance when ordering)
Equipment structure and installation dimensions (according to company standard size)
/>Special ordering requirements need to be stated in advance
Installation precautions:
The non-negative pressure water supply equipment is easy to install: when the equipment is on site, you only need to connect the inlet and outlet pipes, the construction period is short, and the installation is simple.
Before installation, carefully check whether there are any hard objects in the water flow of the pump body to avoid damaging the impeller and pump body during operation.
The installation methods of the pump are divided into rigid connection installation and flexible connection installation.
Tighten the anchor bolts to prevent vibration from affecting pump performance during startup.
Install a regulating valve on the inlet and outlet pipelines of the pump, install a remote contact pressure gauge near the pump outlet, and use a control cabinet to control the pump to operate within rated working conditions to ensure normal use of the pump.
If the discharge pipeline is equipped with a check valve, it should be installed outside the gate valve.
