Title: Analysis of the characteristics of non-negative pressure variable frequency water supply equipment and constant pressure variable frequency water supply equipment.
Introduction: Water is the source of life and is closely related to our daily life. With the development of science and technology, water supply equipment is also constantly upgrading. This article will give you a detailed analysis of the characteristics of non-negative pressure variable frequency water supply equipment and constant pressure variable frequency water supply equipment, so that you can better understand the application of these equipment in life.
1. Characteristics of non-negative pressure variable frequency water supply equipment.
1.1 Components.
The non-negative pressure variable frequency water supply equipment is mainly composed of a water tank, a pressurized pump, a pressure stabilizing tank control device, a pipeline valve and a set of supporting accessories. The tank stores the treated tap water, the booster pump pressurizes the pressure of the pressure transmission, the regulator tank controls adjust the water pressure, and the line valve adjusts the pressure of each outlet pipe.
1.2 How it works.
The working process of the non-negative pressure water supply equipment is as follows: first, the water in the water tank is fed into the pressurized pump through a stainless steel pipeline, and the pressurized pump pressurizes according to the pressure of the pressure transmission to push the water flow. Then, the water passes through the diaphragm pressure tank (pressure stabilizing tank), and the control terminal of the non-negative pressure water supply equipment and the constant pressure inverter play a role in monitoring and adjusting the water pressure to ensure the stability of the water outlet pressure. Finally, the water passes through the outlet line valves, and the pressure in each outlet pipe is adjusted to be consistent.
1.3 Pros.
Non-negative pressure frequency conversion water supply equipment has the following advantages:
1) Energy saving: The equipment adopts frequency conversion speed regulation technology, which automatically adjusts the operation status of the pump according to the actual water demand, and effectively reduces energy consumption.
2) Stability: The water pressure is monitored and adjusted through the constant pressure inverter to ensure that the outlet pressure is stable and meets the demand for domestic water.
3) Safety: The equipment adopts a diaphragm pressure tank to avoid the water pump being directly connected with the tap water pipe network and reduce the risk of pollution.
4) Environmental protection: low noise during the operation of the equipment, which does not affect the lives of residents.
Second, the characteristics of constant pressure variable frequency water supply equipment.
2.1 Causes of pressure instability.
There are four main reasons for the unstable pressure of the constant pressure variable frequency water supply system:
1) Pump failure: The pump is the core of the water supply system, and the failure of the water pump will lead to the instability of the pressure of the water supply system.
2) Pump capacity is too large or too small: The pump capacity must match the load demand of the water supply system, otherwise it will cause pressure fluctuations.
3) Control system problems: The variable frequency constant pressure water supply system relies on the controller to monitor and regulate the operation of the pump, and the failure of the control system will lead to pressure instability.
4) Leaks or blockages: Leaks or blockages in the piping system can also lead to unstable pressure in the water supply system.
2.2 Pros.
Constant pressure variable frequency water supply equipment has the following advantages:
1) Energy saving: The equipment adopts frequency conversion speed regulation technology, which automatically adjusts the operation status of the pump according to the actual water demand, and effectively reduces energy consumption.
2) Stability: Monitor and regulate the operation of the pump through the controller to ensure that the pressure of the water supply system is stable.
3) Safety: The equipment adopts a control system to avoid the pump being directly connected to the tap water pipe network and reduce the risk of pollution.
4) Environmental protection: low noise during the operation of the equipment, which does not affect the lives of residents.
3. Summary. Non-negative pressure variable frequency water supply equipment and constant pressure variable frequency water supply equipment are designed to meet the water supply needs of modern urban high-rise buildings. They all have the advantages of energy saving, stability, safety and environmental protection, which bring convenience to our lives. However, in practical application, we also need to choose the right water supply equipment according to the specific situation, and carry out regular inspection and maintenance to ensure the normal operation of the water supply system.
In the future, with the continuous development of science and technology, water supply equipment will be more intelligent and efficient, bringing more convenience to our lives. At the same time, we should also pay attention to the protection of water resources, cherish every drop of water resources, and jointly build a better home.
Conclusion: Water supply equipment is an important infrastructure of modern urban life, and the characteristics of non-negative pressure variable frequency water supply equipment and constant pressure variable frequency water supply equipment provide us with stable, safe and energy-saving water supply guarantee. Let's focus on water conservation and contribute to a better life.
