ARBURG filter Germany ARBURG model ARBURG price

ARBURG filters are indispensable devices on media transport pipelines, typically installed at the inlets of pressure reducing valves, relief valves, constant level valves, and other equipment. The filter consists of a housing, stainless steel filter mesh, blowdown section, drive mechanism, and electrical control components. As water to be treated passes through the filter cartridge and mesh, impurities are retained. When cleaning is required, simply remove the detachable cartridge, clean it, and reinstall it, making operation and maintenance extremely convenient. It is the "decision-making unit" that issues commands, i.e., it coordinates and directs the operation of the entire computer system. Controllers are divided into combinational logic controllers and microprogrammed controllers, each with its own advantages and disadvantages. Combinational logic controllers are troublesome to design and complex in structure; once designed, they cannot be modified or expanded, but they offer high speed. Microprogrammed controllers are easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, only the corresponding microprogram needs to be rewritten; to add a machine instruction, only a segment of microprogram needs to be added to the control memory. However, it operates by executing a segment of microprogram. A specific comparison is as follows: Combinational logic controllers, also known as hardwired controllers, are composed of logic circuits and rely entirely on hardware to implement instruction functions.

ARBURG filter principle

Water to be filtered enters through the inlet, flows through the filter screen, and exits via the outlet into the user's required piping for process circulation. Particulate impurities in the water are retained inside the filter screen. As this cycle continues, the amount of retained particles increases, causing the filtration rate to slow down. Meanwhile, untreated water continues to enter steadily through the inlet, causing the filter pores to become progressively smaller. This creates a pressure differential between the inlet and outlet. When the pressure differential reaches the set value, the differential pressure transmitter sends an electrical signal to the controller. The control system then starts the drive motor, which rotates the shaft via the transmission assembly. Simultaneously, the blowdown port opens to discharge contaminants. Once the filter screen cleaning is complete, the pressure differential drops to its minimum value, the system returns to the initial filtration state, and normal operation resumes. The system operates in two modes: polling mode and identification mode. In polling mode, the controller continuously sends query codes to the card reader and receives response commands from it. This mode persists until the card reader detects a card. When the card reader detects a card, it sends a different response to the controller's polling command. In this response, the card reader transmits the internal code data read from the proximity card to the access control controller, causing the access control controller to enter identification mode. In the identification mode of the access control controller, the controller analyzes the internal code of the proximity card, compares it with the card data stored in the device, and executes subsequent actions. After completing the data reception, the access control controller sends a response command to the card reader to restore its status, while the access control controller returns to polling mode.

ARBURG filter filtration speed

When solid particles in a suspension are large and uniform in grain size, the pores in the filter cake layer are relatively open, allowing the filtrate to pass through at a higher speed. Using coagulants to aggregate fine particles into larger clumps helps improve filtration speed. For suspensions where solid particles settle quickly, filters that feed onto the upper part of the filter medium are used, aligning the filtration direction with gravity. Coarse particles settle first, reducing clogging of the filter medium and filter cake layer. In difficult-to-filter suspensions (such as colloids), mixing in coarser solid particles like diatomaceous earth or expanded perlite can loosen the filter cake layer. When the filtrate viscosity is high, heating the suspension can reduce viscosity. These measures all accelerate filtration speed.

ARBURG filter performance features

1. High efficiency, precise filtration: Special structural disc filter technology offers precise and sensitive performance, ensuring that only particles smaller than the required size enter the system, making it the most effective filtration system. Specifications include 5μ, 10μ, 20μ, 55μ, 100μ, 130μ, 200μ, and more. Users can select filter discs with different precisions according to water usage requirements. System flow rate can be flexibly adjusted as needed. 2. Standard modular design, space-saving: The system is based on standard disc filter units and designed modularly. Users can select units as needed, offering flexibility and strong interchangeability. The system is compact and occupies very little space, allowing flexible installation in corner spaces. For example, equipment handling approximately 300m3/h of water occupies only about 6m2 (for general water quality, filtration grade 102μ).
