Model Definition & Meaning

Min. inlet pressure

If the pressure in the pump is lower than the vaporisation pressure of the conveyed liquid, cavitation may occur, in order to avoid cavitation, ensure that the inlet side of the pump has - minimum pressure, the maximum suction lift H (m), can be calculated according to the following formula:

H=Pbx10.2-NPSH-Hf-Hv-Hs

H - Max. suction (m)

Pb - atmospheric pressure (bar)

System pressure (bar) in a closed line can be considered as a closed system NPSH- Net Positive Suction Pressure (m)

Can be read on the NPSH curve in the performance curve corresponding to the maximum flow rate.

Hf - Pipeline loss at the inlet (m), which corresponds to the max. flow rate that the pipeline may generate.

Hv - The magnitude of the value of the vapour pressure (m) of a liquid depends on the temperature of the liquid and the value of the vapour pressure of the liquid.

Hs - Safety margin (m), min. 0.5m pressure head.

By calculation, if "H" is positive, it means that the pump can be operated at a maximum suction range of "H"; if "H" is negative, it means that the pump must have a minimum pressure of "H" meters of head at the inlet in order to operate properly.

Note: In general, the above calculations are not performed. Calculate "H" only if the pump is to be used in the following cases: 1. High liquid temperature

2. Liquid flow rate exceeds rated value.

3. Large suction inlet or long intake pipeline.

4. The system pressure is too small.

5. Poor inlet conditions.

Pipeline installation conditions

• When installing pipelines, it is necessary to ensure that the pump casing does not bear pipeline stress

• The suction and discharge pipes must be properly sized, while taking into account the inlet pressure of the pump.

• Install pipework to avoid air resistance, especially on the inlet side of the pump. (see figure on the right)

• Install an isolation valve at each end of the pump so that the system does not have to be drained when the pump needs to be cleaned or serviced.

• Ensure that the pipework is adequately supported as close to the pump as possible (inlet side and outlet side). The butt flanges should be securely fastened to the pump flange without being subjected to tensile stresses, the presence of which can damage the pump.

OZONE DISINFECTION

Ozone generation methods based on the principle can be classified into photochemical function, electrochemical function, atomic radiation and corona discharge. Wherein, corona discharge is widely applied to ozone generator. The basic principle of generating ozone with the corona discharge method is the ozone generator which consists of one pair of electrodes, dielectric and discharging gap. When AC high voltage is imposed to two electrodes, high-speed electrons and oxygen molecules impact with each other, corona discharge occurs in the gap under the action of external high energy, oxygen gases are ionized, concentration of oxygen ions in the gap increases significantly, oxygen ions and oxygen molecules react with each other to generate ozone. The generation process is also a process of thermal reaction where heat energy is released.

With the help of the strong oxidation ability of ozone, the cell wall and RNA of bacteria are destructed, and DNA, RNA, protein, lipid, polysaccharide and other macromolecular polymers are decomposed. It can penetrate into the cell membrane tissue to cause permeability distortion of cells, resulting in decomposition and death of cells. In addition, the DNA, bacterial parasites and other contents in the dead bacteria can be decomposed and killed, so as to achieve the purpose of sterilization.

AOP (Advanced Oxidation Process) is a disinfection technology marked by the generation of hydroxyl radicals (• OH). The oxidation capacity of hydroxyl radicals is more effective and stronger than other disinfection methods. The disinfection process is controllable, safe and harmless to the human body, and the final products are water and inorganic salts, which are non-polluting to the environment.

Principle - Core Substance: "Hydroxyl Radicals"

O₃+H2O+hv → O₂+H2O2 H₂O₂+hv →2·OH

The generated hydroxyl radical (-OH) is a stronger oxidant than ozone (Ox).

AOP water treatment equipment adopts internationally advanced oxidation technology, specific light source excitation photocatalytic material, and combined with ozone advanced oxidation, high efficiency mixing technology, thus generating hydroxyl radicals with strong oxidative properties.

Hydroxyl radicals directly damage cell membranes and rapidly destroy cell tissues. The microorganisms and organic matter in water are rapidly decomposed into CO: and Hs O, so that the microorganisms lose the material basis for resurrection and reproduction,thus achieving the purpose of complete decomposition of microorganisms and organic matter in water.

OZONE OFF GAS DESTRUCTOR

In ozone water treatment systems, not all of the ozone is transferred to the water and escapes. Ozone gas is highly oxidizing In addition to causing damage to the surrounding equipment and instrument, ozone gas will also pollute the environment, stimulate the human respiratory system, and be harmful to human health. Therefore, ozone off gas that have not been fully absorbed need to be destroyed and decomposed before being discharged into the air.

OXYGEN SYSTEM

OXYGENATION COLUMN

The oxygenation column are designed to optimize the saturation of gases in water, and can obtain gas transfer efficiencies of up to 100%. The operation of the cone is simple: water and gas (either pure oxygen, ozone or other gas) enter from the top where the velocity is reduced as the body of the vessel expands. As the water moves to the bottom of the vessel, the gas rises to the top and is constantly sheared. The undissolved gas keeps returning to the top, and when adjusted properly, only water without bubbles can exit the bottom. At higher pressures, the dissolved oxygen concentration could be increased significantly above saturation

TEMPERATURE CONTROL

Water quality is extremely important and critical for aquaculture and aquarium. Water temperature not only directly affects the metabolic activities of aquatic life, but also affects their growth by changing other elements of the water indirectly. According to the biological habits of different species, fish can be divided into cold water fish, warm water fish and tropical fish. The right and stable water temperature is essential to their health. Different fishes have different requirements for water temperature, some fishes need the water to be heated at a constant temperature while some fishes need to be cooled at a constant temperature.

1.Economical and high-efficiency

Assembled from corrugated plates formed by one-time stamping and has low metal consumption. When using corrosion-resistant materials, the investment cost is significantly lower than other types of heat exchangers.

2.High heat transfer coefficient

When the Reynolds number> 10, severe turbulence can be generated, and the general total heat transfer coefficient can be as high as 3000 -7000W/m²k.

3.Less heat loss

The heat exchange is carried out in the form of countercurrent, which can reach a temperature difference of 1 C at the end, and the thermal efficiency is ≥95%. Only the edges of the plates are exposed, with minimal heat loss and no need for heat preservation.

4.Compact structure, small footprint

A small space can provide large heat exchange area, and its occupied space is a small part of other types of heat exchangers, and no additional space for disassembly and assembly is required.

5. Long service life and easy maintenance

High turbulence degree of water flow, effectively reduces scaling and the stainless steel plate is not corroded. When it needs to be disassembled and cleaned, just loosen the fastening bolts, and the gasket can be quickly replaced.

6. Wide adaptability

Each model has four different specifications of plates, and different combinations can flexibly meet various conditions of use. The plate is an independent unit, and the number of plates can be increased or decreased to match the changing heat requirements
