The bag filter used for liquid filtration consists of three parts: the filter container, the supporting screen basket and the filter bag. Its original working principle is pressure surface filtration. In the filtration system, the filter bags are supported by the supporting screen baskets. The liquid to be filtered flows in from the top of the filter bag and is evenly distributed on the inner surface of the filter bag without the negative effect of turbulence. The filtered particulate impurities are throttled in the filter bag, completing the filtration process. The bag filter can effectively remove particles of different sizes from the liquid, thereby achieving the purpose of liquid filtration, purification, separation and recovery. There are various types of bag filters. Classified by the number of filter bags, they can be divided into single-bag, double-bag and multi-bag types. According to the way the liquid flows, there are side-entry type and top-entry type. According to different usage requirements, bag filters can be matched with various types of filter bags of different structures, shapes and materials, and their filtration accuracy is 1
Details >What matters should be noted when reverse osmosis equipment is in operation
For pure water equipment, it is necessary to know some information about the equipment so that we can use it better. I. What is this device used for? A simple sentence: Pure water equipment is the equipment for producing pure water. Moreover, pure water can be used in many fields of our lives: domestic drinking, chemical industry, breeding, planting, beverages, etc. What other features does this device have? (1) By applying the current reverse osmosis water treatment technology to prepare pure water, substances harmful to human health in tap water can be removed. (2) Filter out the water and drink it directly, saving energy consumption. (3) Automatic control of the water production process. (4) It has an RO membrane cleaning function, which can effectively extend the service life of the RO membrane. Iii. Why are pure water equipment being used more and more
Details >Tips for using water softening equipment
Softening water equipment has functions such as scale prevention and removal, anti-corrosion and rust prevention, algae elimination, and water quality activation. It can be widely applied to air conditioning systems, industrial cooling systems, heat exchange systems, hot water boiler systems and other various water-using equipment systems. The usage method of the water processor: ① Check whether the power cord plug is properly inserted. ② Connect the 220V 50z power supply. ③ Turn on the main unit switch. The switch indicator light will be on and the working indicator light will be on. ④ Turn off the main unit switch and cut off the 220V 50Hz power supply. Precautions for using the water softening equipment: ① The user's power supply should meet the requirements of 220V ± 10% and 50Hz-2%. Before installation, it is necessary to check whether the inlet and outlet dimensions of this product are consistent with the dimensions of the pipeline. ③ Install it before the water inlet of the equipment that needs to be descaled or prevented from scaling or
Details >Supervision and Administration Rules for Boiler Water Treatment (2008 Edition)
"Zhang" General Provisions "Strip " In order to standardize the water treatment work of boilers, prevent and reduce accidents caused by boiler scaling, corrosion and deterioration of steam quality, and ensure the economic, energy-saving and environmentally friendly operation of boilers, this rule is formulated in accordance with the "Regulations on the Supervision of Special Equipment" and relevant boiler technical specifications. "Strip " The boiler water treatment as stipulated in these rules mainly refers to the measures taken to prevent boiler scaling and corrosion and ensure the quality of water and steam (including boiler cleaning). Article 3 This rule applies to fixed pressure-bearing boilers (hereinafter referred to as boilers) that use water as the medium within the scope stipulated in the Special Equipment Supervision Regulations. Fourth
Details >How to choose a metering pump?
The metering pump mainly consists of three parts: power drive, fluid transportation and regulation control. Metering pumps can be classified into motor-driven, electromagnetic driven and pneumatic types based on their power drive. According to the fluid transportation mode, they are classified into plunger pumps and diaphragm pumps. Diaphragm pumps are further divided into mechanical transmission diaphragm pumps and hydraulic transmission diaphragm pumps. Since the coagulants used in water treatment projects are mostly corrosive liquids, diaphragm pumps are often adopted. When choosing a metering pump, it is generally necessary to know the rated pressure, rated flow rate, type (diaphragm type or plunger type), and flow-through material. The rated pressure of a metering pump usually refers to the outlet pressure. When selecting a model, it is generally advisable to choose a rated pressure that exceeds the actual operating pressure by 10% to 20%. This not only saves resources and reduces costs but also improves the metering accuracy of the metering pump during actual use. When the metering pump is in operation, it is generally at a rated flow rate of 10

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.
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 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.
