Which equipment is best for hotel domestic water supply system? Please explain the difference in detail

The hotel's domestic water supply system can use box-type non-negative pressure water supply equipment or ultra-quiet water supply equipment

Box-type non-negative pressure water supply equipment:

1. Saving investment: Saving investment by about 50%. There is no need to build a reservoir or roof water tank. Overlay water supply is used, which reduces the initial investment in equipment.

2. High efficiency and energy saving, low operating cost: It can make full use of the water supply pressure of the municipal pipe network, compensate for the difference, and does not generate negative pressure. Compared with traditional water supply equipment, it can save 30%-60% of energy. Even in the event of a power outage, water pressure and water supply from the municipal pipe network can be maintained.

3. High degree of intelligence, simple operation, saving manpower: The equipment is controlled by a fully automatic intelligent controller, which can be adjusted according to the user's water consumption and the tap water pressure of the pipe network, and is unattended. . And it adopts human-machine interface (text, number) display to allow customers to see the operating status of the equipment more intuitively.

4. Environmental protection and sanitation: The equipment is fully enclosed and operates to completely eliminate secondary pollution of water sources.

5. Complete protection functions: It has perfect automatic protection functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, water shortage, etc. Under abnormal circumstances, signal alarms, self-tests, fault judgments, etc. can be carried out.

6. Small footprint and easy installation: The whole set of equipment has only three parts: a set of water supply control cabinets, a non-negative pressure steady flow tank and a water pump unit. The installation is very simple and convenient.

7. Extend the service life of the equipment: multiple pump units can be reliably soft-started to avoid impact on the power grid and pipe network, and they can run in turns, greatly extending the service life of water pumps and motors. Equipment life can be extended by more than 3 times.

The characteristics of ultra-quiet water supply equipment are:

1. Ultra-low silence: <40 decibels, which is better than the national noise standard.

2. Small footprint: No need to install water towers, pools, water tanks, etc., or a dedicated pump room, saving floor space, reducing construction costs, and saving more than 50% to 70% compared with conventional water supply equipment. area.

3. High efficiency and energy saving: using an intelligent control system, connected to the municipal pipe network, the difference will be compensated. That is, the equipment only compensates for the difference between the inlet pressure of tap water and the required pressure. When the tap water pressure When the requirements are met, the equipment stops working and everything is directly supplied by municipal pressure. Compared with ordinary water supply equipment, it can save 30% - 90% of electricity.

4. Fully automatic operation: Under the water supply pressure set by the equipment, it operates fully automatically, and can also be monitored remotely, making it convenient to use and protect.

5. Complete protection functions: It has perfect automatic protection functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, water shortage, etc. Under abnormal circumstances, signal alarms, self-tests, fault judgments, etc. can be carried out.
