What are the working principles and functions of towerless water supply equipment?

1. The working principle of tower-free water supply equipment: tower-free water supply is air pressure water supply.

2. Composition: The towerless water supply is composed of a towerless water supply device (pressure tank), a pressure switch, a pressure gauge, a water pump, a pipe network and a supporting valve, which is divided into two parts: pipeline and circuit.

3. Working process: There is uniform atmospheric pressure air in the towerless water supply device (pressure tank), and it becomes a sealed container after installing the pressure switch, pressure gauge and pipe network. The water pump is started, the water level in the tank rises, and the air in the tank is compressed, generating air pressure.

When the air pressure reaches the set pressure, the pump stops working. Due to the air pressure, the water in the tank can flow out at high speed. After the water level in the tank drops, the air pressure decreases, and when the set pressure is reached, the water pump starts automatically, and the cycle starts repeatedly, which is essentially a small household tap water system.

4. Features and application: As a set of household tap water, it can enable farmers to enjoy the same convenience and hygiene as urban residents. The tower-free water supply pressure is large and the flow rate is high, which can meet the water pressure requirements of solar energy, water heaters, washing machines, and toilet urinals, and replace traditional water tanks, water hoards, and water jars.

When the water pressure of urban tap water is insufficient, it can be used for secondary pressurization. It can be used for fire fighting, agricultural irrigation, and centralized water supply.

The development of tower-less water supply now includes pneumatic tower-free water supply equipment, frequency conversion water supply equipment, non-negative pressure water supply equipment, etc. As the name suggests, it is a water supply equipment without a water tower, and the water tower here refers to the high-level water tower, which was built of bricks at the earliest, and the water supply without a tower is definitely not a single frequency conversion water supply equipment. At present, towerless water supply equipment is widely used in enterprises and institutions, residential areas and rural areas for production, living and office water.

The water supply is in 20-2000 households. The daily water supply is 20-50,000 m3, and the water supply height is up to 10 meters, that is, 10 floors. The upfront investment cost is greatly reduced and fully automatic control is realized.

The working principle of secondary water supply equipment and towerless water supply equipment manufacturers.

The secondary water supply equipment is stacked according to the pipe network, and the water supply equipment is compared with the set pressure by detecting the actual pressure according to the actual situation. When the stacking pressure of the municipal pipe network is higher than the set pressure, the unit is in a shutdown state, and the tap water can be directly supplied to the user through the municipal pipeline. When the water supply pressure of the pipe network is lower than the set pressure, the stacked water supply equipment of the pipe network automatically enters the stacked working state, and the unit forms a closed-loop control system through the pressure sensor, the water pump and the constant pressure frequency conversion control cabinet, and continuously adjusts the pump speed and the number of pumps put into operation with the change of water consumption to keep the water supply pressure constant.

Completely solve the serious secondary pollution of water quality in the water tank in the secondary water supply. The original clean tap water of the towerless automatic water supply device and the tower-free water supply equipment manufacturer will inevitably be polluted by sundries, dirt, water breeds and even other harmful substances when put into the pool, which will directly affect the health of residents. When the municipal tap water is put into the pool, the water pressure becomes zero, so that the original pressure of the municipal pipe network is wasted.

The pressure of the municipal pipe network cannot be used, resulting in energy waste; The need to build a pool or tank not only greatly increases the floor space and civil engineering investment, but also increases the difficulty of the project and the construction period. Most of the pools or water tanks of towerless automatic water supply devices and towerless water supply equipment manufacturers adopt civil structures, and problems such as running, rising, dripping, and leaking are unavoidable, and they need to be cleaned regularly, resulting in the waste of water resources and the increase in operating costs. Poor reliability of water supply.

The number of equipment is large, and there are many control links, which are prone to failure. A power outage is a water outage. The pump stops working when the power goes out, and all users stop supplying water.

The equipment is scattered, the degree of automation is low, the manpower is wasted, and the operating cost increases.

Overview of towerless automatic water supply and towerless water supply equipment manufacturers.

ZBW series intelligent pipe network laminated water supply equipment is a kind of water supply equipment developed by Zhongbori that is directly connected to the municipal pipe network and will not have an impact on the municipal pipe network. On the basis of frequency conversion and constant pressure, the pressure of the municipal pipe network and the pressure of the lifting pump are superimposed, so that the domestic water supply is more energy-saving and environmentally friendly, and it is an ideal replacement product for the traditional secondary water supply. The superimposed water supply equipment of the pipeline network is composed of a frequency conversion control cabinet, an automatic control system and wireless communication equipment, a pump unit, a voltage regulator compensator, a negative pressure eliminator, a pressure sensor, a valve, an instrument and a pipeline system.

A towerless water supply unit is a bottom-up direct water supply system in which booster pumps pump water from a low-level storage tank to a high-level water point. The tower-free water supply equipment does not mean that there is no one kind of pool water supply method, but the high water tower is changed to a stainless steel water tank with better hygiene level and better sealing, which is installed at the lowest level of the building. Towerless water supply equipment is supplied directly to households from the bottom up by pumps.

According to the size of the water tank and whether it overlaps, it can be divided into box-type variable frequency constant pressure water supply equipment, box-type non-negative pressure water supply equipment and box-type non-negative pressure water supply equipment. No matter what kind of tower-free water supply equipment, it has the functions of fully automatic operation, constant pressure, and automatic adjustment of water supply. Their working principles, processes, and structure diagrams are described below:

The structure and principle of the box-type variable frequency constant pressure water supply equipment without tower water supply equipment The variable frequency constant pressure water supply equipment is composed of a water tank and a water supply unit. Tap water accumulates in the tank, which is then pumped from the tank and pressurized upstairs. The number of pumps and the speed at which they operate are determined by the amount of water used.

Through the frequency conversion pump control cabinet system, the target value set by the pressure value of the pipe network is collected and compared, and the frequency value is dynamically output after a series of calculations to control the speed of the motor. For the specific working process, please refer to the constant pressure water supply control principle introduced below.

Towerless water supply is to use inverter pumps to supply water to the upper floors.

Water supply from the water tower is a self-weight water supply that uses the water after the water is pumped to the water tower.

Tower-less water supply equipment.

Advantages of tower-free water supply equipment:

1. Reasonable operation, high reliability and flexible configuration; 2. The investment in tower-free water supply equipment is small and the investment is small; 3. Reduce pollution, because the water tower and high-level water tank are canceled, the secondary pollution is reduced; 4. High efficiency and energy saving of tower-free water supply equipment: It can be seen from the electrical formula that the power consumption of the system motor is formed by the cubic relationship between the motor speed of the system, and the water output of the pump is proportional to the speed of the motor when the water pressure is unchanged.

The high spring is the starting pressure, and the low spring is the de-energizing pressure. Clockwise.

Upward adjustment is an increase in pressure and a decrease in downward pressure. In the process of adjustment, it must be adjusted in a small amount, and the range of positive and negative adjustment is: small grids). Large and non-standard adjustments can lead to pressure switches.

Malfunction. When the pressure reaches the specified limit, the contact pressure gauge.

Or the pressure switch stops the pump automatically via the control cabinet. The water pressure in the equipment is higher than the outside pressure and is automatically sent to the water supply network.

When the pressure in the tank drops, the water level drops to the specified limit, the electric contact pressure gauge or pressure switch restarts the pump through the slag control cabinet, and so on, so that the equipment does not stop supplying water, and when the tank energy gas drops, the pump starts.

Towerless water supply is actually a variable frequency constant pressure water supply system.

The variable frequency constant pressure water supply control system adjusts the output frequency through the measured pipe network pressure and the calculation of the built-in PID regulator of the frequency converter to realize the constant pressure water supply of the pipe network. The frequency overrun signal of the inverter (generally used as the pressure limit signal of the pipe network) can notify the PLC to switch the inverter pump logic in time. To prevent water hammer from occurring, the start and stop of the pump will be connected to its outlet valve.

The working principle of the towerless water supply system is as follows:

Let's assume that the whole system consists of four pumps, a frequency converter, a PLC, a pressure transmitter and several auxiliary components. The functions of each part are as follows: the pressure transmitter installed on the water supply pipeline converts the pressure of the pipe network into an electrical signal of 1-5 volts; The inverter is used to adjust the speed of the water pump to regulate the flow rate; PLC is used for logic switching.

In addition, the above-mentioned system is equipped with peripheral auxiliary circuits to ensure that the automatic control system can maintain the operation of the system through manual adjustment in the event of a failure, so as to ensure continuous production.

The principle of towerless water supply is as follows:

The working process of the towerless water supply device is that the pump starts, and the water is injected into the pressure tank through the check valve, so that the pressure in the tank increases, and when the pressure reaches the upper limit of the set pressure, the pressure automatic controller automatically closes the water pump and stops the water pump.

When the pressure decreases to the lower limit of the set pressure, the pump is automatically controlled to start, and the water supply tank is automatically filled with water, so that the towerless water supply device does not stop supplying water and runs automatically.

Correct water intake orientation for towerless water supply:

When a single water source is supplied, the water intake of the towerless water supply equipment should be as close as possible to the primary water use area of the large user location, and the water intake should be located in the middle of the water use area when the water in the water use area is evenly hooked. When there are many water sources, the location of other water supply points should be known, and the new water intake water supply points should make the water supply of the whole system even, and the most ideal situation is to form a diagonal water supply with the original water supply point.

In this way, the users who were originally at the end of the sales and training pipe network can obtain higher water pressure and improve the quality of service, and can reduce the pump head of the original water supply point and save energy consumption. <>

1. The working principle of tower-free water supply equipment: After the tower-free water supply equipment is put into use, the water from the pipe network enters the steady flow pool, and the air in the pool is discharged by the vacuum eliminator. When the water is full, the vacuum eliminator automatically shuts off.

When the pressure of the distribution network can meet the water demand, the system supplies water directly to the distribution network through a bypass check valve.

When the pressure of the water supply network cannot meet the water demand, the pressure signal of the system is fed back to the frequency conversion controller by the remote pressure gauge, and the water pump operates, and the speed and constant pressure water supply are automatically adjusted according to the water consumption. If the pump in operation reaches the power frequency speed, another pump will be started for frequency conversion operation.

2. Functions of towerless water supply equipment:

1) Towerless water supply equipment can replace high-level water tanks and water towers, and the pressure is relatively stable. It avoids the frequent start of the pump, with high efficiency, energy saving and low noise.

2) Tower-free water supply equipment does not need to build water towers, with less investment and less land occupation. It adopts automatic water and gas adjustment, automatic operation, energy saving, and automatic connection of tap water. Water is still available after a power outage and no supervision is required for several years after commissioning.
