Nowadays, people pay more attention to water safety, and the choice of water supply equipment directly affects the safety and health of water use. At the same time, correct operation is necessary to ensure the stability and safety of equipment. So, what are the operating procedures for non negative pressure water supply equipment? Follow Sanli Water Supply to learn more.

　　Precautions for the correct use of non negative pressure water supply equipment

1. Qualified guarantee of water supply equipment

Non negative pressure water supply equipment should have a product qualification certificate or certification mark, a quality inspection report from the product quality and technical supervision department, and a hygiene license from the health supervision department.

In addition, a control system should be installed to ensure that the water supply network and water pressure are not lower than the set pressure value, as well as reliable anti negative pressure devices.

2. Recognized by the competent authorities

With the recognition of local administrative authorities (such as the Construction Department, Water Bureau, etc.) and water supply departments (such as water companies, etc.), these departments can determine whether it is possible to set up pipe network pressure water supply methods and the scale of use of non negative pressure water supply equipment based on the overall situation of the water supply network.

3. Ensure there is a water supply network

The water supply network can be a municipal water supply network, a self provided water source water supply network, an outdoor water supply network, or an indoor water supply network, which can directly absorb water from non negative pressure water supply equipment.

4. Ensure that the water supply network can supply water normally

In order to ensure the normal use of non negative pressure water supply equipment, the water supply network needs to ensure normal water supply, and the flow rate should be able to meet the flow requirements of the unit during peak and low peak periods, or the design second flow rate requirements; The water pressure cannot be lower than the local water supply service pressure value.

5. Used under insufficient water supply pressure

Non negative pressure water supply equipment is a device that directly absorbs water and pressurizes it from the water supply network. Only when the water supply pressure is not sufficient, a pressurization device needs to be installed, but this is a very important condition.

6. Confirm that the water usage is normal

Avoid situations where water supply is frequently interrupted, water usage is too concentrated, instantaneous water usage is excessive, and there are no effective technical measures in place.

7. Other conditions

In addition to necessary conditions, other requirements should also be noted, such as whether the water supply network is a ring network, whether the diameter of the water supply website and the inlet pipe diameter of the water supply equipment match.

　　What are the operating procedures for non negative pressure water supply equipment

1. The inlet pipe is directly connected to the tap water pipe network, and water is pressurized into the equipment inlet pipe under the residual pressure of the tap water pipe network;

The pressurized water pump of the equipment continues to pressurize on the basis of the remaining pressure of the inlet water, and increases the water supply pressure to the pressure required by the user before supplying water to the outlet pipe network;

2. When the user's water consumption exceeds the water supply of the tap water network, the pressure of the inlet pipe network decreases. When the pressure at the inlet of the equipment drops to an absolute pressure less than 0, the negative pressure prevention and control device in the equipment automatically starts working;

Adjust the operating status of the equipment until it stops and is ready for standby, ensuring that the pressure in the inlet pipe network no longer decreases and does not have adverse effects on the tap water pipe network;

3. When the water supply capacity of the tap water network is restored and the pressure of the inlet network is above the protection pressure, the equipment will automatically start and resume normal water supply;

When the remaining pressure in the water supply network meets the user's water supply requirements, the equipment automatically enters a sleep state and is supplied directly to the user by the water supply network. When the water supply is insufficient, the equipment automatically resumes operation;

4. When the user does not use water or uses very little water, the non negative pressure water supply equipment automatically enters a shutdown sleep state;

When the small flow stabilizing and pressure maintaining tank located on the outlet side of the equipment is used to maintain the number of users' water usage and pipe network leakage, and the stabilizing and pressure maintaining tank cannot maintain the required pressure of the water supply pipe network, the equipment will automatically wake up and resume normal operation.

During the operation of the equipment, the remaining pressure of the tap water pipeline network is fully utilized, which never causes adverse effects on the tap water pipeline network while maximizing the satisfaction of user needs, reducing water supply energy consumption, and achieving optimal operation of the water supply system.
