FLECK control Valve (Boiler Softening Water Equipment)

I. Hazards of Boiler Scaling Boilers are indispensable power and heating equipment in modern industrial society. After long-term operation, boilers develop problems such as scaling and rusting, which lead to poor heat transfer performance, reduced boiler efficiency, increased fuel consumption, and higher operating costs. At the same time, there are issues such as bulging of boiler tubes, explosion risks, and shortened boiler lifespan. Therefore, after the boiler is scaled, necessary methods should be taken to remove the scale and rust and prevent their recurrence. After long-term operation, boilers inevitably develop problems such as scale and rust. The main reason for the formation of scale in boilers is that the feed water contains hardness components. After continuous evaporation and concentration under high temperature and high pressure, a series of physical and chemical reactions occur in the furnace, forming hard and dense scale on the heating surface. Scale is the "scale" of boilers. All kinds of harms

Common problems that occur during the operation of FLECK control valves

The FLECK control valve of FLECK is the core component of the water softener, consisting of a multi-way valve and a regeneration control device. Now let's talk about the common problems that occur during the operation of the FLeck control valve. 1. The soft water output is substandard. The system's feed water pressure does not meet the requirements. The FLECK water softener requires a feed water pressure between 2 and 6Kg/cm ². When the feed water pressure is less than 1.75 Kg/cm ², the flow rate of the water ejector used for salt suction is too low to generate sufficient negative pressure to draw in salt water. It is manifested as insufficient salt absorption (there is still remaining saturated brine in the salt tank after the regeneration process is completed), a decline in the regeneration quality of the water softener, and the output of the equipment in the next water production cycle is definitely insufficient. The solution to this problem is to increase the water supply pressure to meet the requirements. Generally, a booster pump can be used to achieve this. When the water supply pressure is greater than 6 K

Points to note for the daily operation and maintenance of metering pumps in winter

The metering pump is a special positive displacement pump that can meet the requirements of various strict process flows. Its flow rate can be adjusted steplessly within the range of 0-100%, and it is used to transport liquids, especially corrosive liquids. Metering pumps are also known as quantitative pumps or proportional pumps. The metering pump belongs to the reciprocating positive displacement pump and is used for precise metering. Generally, the stability accuracy of the metering pump is required not to exceed ± ± ±. 1%. Generally speaking, there are two types of metering pumps: plunger metering pumps and diaphragm metering pumps. The plunger metering pump has the advantages of high metering accuracy, wide adjustment range and high pressure. However, there is leakage at the packing seal. After the packing is corroded and worn, it will affect the metering accuracy of the pump. The flow rate of this type of metering pump is generally 4 to 4000 liters per hour, and the pressure is usually around 5 liters per hour. Below 105 pascals. The main body of the diaphragm metering pump

Three factors to consider when choosing reverse osmosis (RO) membranes

Reverse osmosis membranes are the core components for achieving reverse osmosis. They are artificial semi-permeable membranes with certain characteristics made by simulating biological semi-permeable membranes. It is generally made of polymer materials. Such as cellulose acetate membrane, aromatic polyacylhydrazine membrane, aromatic polyamide membrane. The diameter of the surface micropores is generally between 0.5 and 10nm, and the degree of permeability is related to the chemical structure of the membrane itself. Some polymer materials have good salt repulsion, but their water permeation rate is not good. Some polymer materials have a chemical structure with more hydrophilic groups, so the permeation rate of water is relatively fast. The three factors to consider when choosing a reverse osmosis (RO) are: desalination rate, water production, and recovery rate. 1. Desalination rate and salt Permeation rate of RO Reverse Osmosis Membranes The desalination rate of RO reverse osmosis membrane elements is determined during their manufacturing and forming process, and the level of desalination rate depends on the reverse osmosis RO

12 Common Problems and Causes of Reverse Osmosis Equipment

Reverse osmosis equipment is to pass the raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc. Then, it is pressurized by a pump and uses reverse osmosis membranes (RO membranes) with a pore size of 1/10,000 μm to turn high-concentration water into low-concentration water. At the same time, it isolates a large amount of industrial pollutants, heavy metals, viruses and other impurities mixed in the water. So as to meet the physical and chemical indicators and hygiene standards for drinking water and produce pure water. Reverse osmosis equipment is commonly used in the electronics industry, pharmaceutical industry, beverage industry, seawater, brackish water extraction, and domestic water supply, etc. Now let's talk about 12 common problems and causes of reverse osmosis equipment. 1. Low water supply pressure; The feed water flow rate is inappropriate. B System leakage; C Insufficient inlet water pressure of the high-pressure pump or leakage at the pump section

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
