RAVARINI filter, German RAVARINI model, RAVARINI price

The RAVARINI filter is an essential device 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. Water to be treated passes through the filter cartridge containing the mesh, where impurities are retained. When cleaning is required, simply remove the detachable cartridge, clean it, and reinstall it, making operation and maintenance extremely convenient. It acts as the "decision-making unit" that issues commands, coordinating and directing 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 difficult to design and have complex structures; once designed, they cannot be modified or expanded, but they offer high speed. Microprogrammed controllers are easier to design, have simpler structures, and are easy to modify or expand. Changing the function of a machine instruction only requires recompiling the corresponding microprogram; adding a machine instruction only requires adding a segment of microprogram to the control memory. Specific comparisons are as follows: Combinational logic controllers, also known as hardwired controllers, are composed of logic circuits and rely entirely on hardware to implement instruction functions.

RAVARINI filter principle

Water to be filtered enters through the inlet, flows through the filter mesh, and exits into the user's required pipeline for process circulation. Particulate impurities in the water are trapped inside the filter mesh. As this cycle continues, the amount of trapped particles increases, slowing the filtration speed. Meanwhile, untreated water continues to enter, causing the filter pores to become increasingly clogged, creating a pressure difference between the inlet and outlet. When this differential pressure reaches the set value, the differential pressure transmitter sends an electrical signal to the controller. The control system starts the drive motor, which rotates the shaft via the transmission assembly. Simultaneously, the blowdown port opens to discharge the contaminants. Once the filter mesh is cleaned, the pressure drop decreases to its minimum value, and the system returns to the initial filtration state for normal operation. The access controller operates in two modes: patrol mode and identification mode. In patrol mode, the controller continuously sends query codes to the card reader and receives responses. This mode persists until the card reader detects a card. Upon detecting a card, the reader sends a different response to the controller's patrol command, transmitting the internal code data read from the proximity card to the access controller, which then switches to identification mode. In identification mode, the access controller analyzes the proximity card's internal code, compares it with card data stored in the device, and executes subsequent actions. After completing the data reception, the access controller sends a response command to the card reader to reset its status, and the access controller returns to patrol mode.

RAVARINI 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. In difficult-to-filter suspensions (such as colloids), mixing in coarser solid particles like diatomaceous earth or expanded perlite can loosen the filter cake. If the filtrate viscosity is high, heating the suspension can reduce viscosity. These measures all help accelerate filtration speed.

RAVARINI filter performance characteristics

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 others. Users can select filter discs of 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 minimal space, allowing flexible installation in corner spaces. For example, equipment handling a water volume of approximately 300m3/h occupies only about 6m2 (for general water quality, filtration grade 105μ).
