Operating control device for water demineralizing sodium bed, control method and fault judgment method

Abstract

The invention discloses an operating control device for a water demineralizing sodium bed, a control method and a fault judgment method. The operating control device comprises a multi-valve controllerand the water demineralizing sodium bed, wherein the water demineralizing sodium bed communicates with a feedwater pipeline, an upper drainage pipeline, a lower drainage pipeline, a produced water pipeline, a brine pipeline and a backwashing water pipeline, a feedwater hydraulic operated valve is arranged on the feedwater pipeline, an upper drainage hydraulic operated valve is arranged on the upper drainage pipeline, a lower drainage hydraulic operated valve is arranged on the lower drainage pipeline, a produced water hydraulic operated valve is arranged on the produced water pipeline, a brine hydraulic operated valve is arranged on the brine pipeline, and a backwash water hydraulic operated valve is arranged on the backwashing water pipeline. Compared with the prior art, the water demineralizing sodium bed is controlled by employing the hydraulic operated valves, and a plurality of power water supplies can be accessed simultaneously, so that the stability of operating of the water demineralizing sodium bed is powerfully stabilized, and the fault rate of equipment is lowered greatly.

Description

technical field [0001] The invention relates to the technical field of softened water equipment, in particular to an operation control device, a control method and a fault judgment method of a softened water sodium bed. Background technique [0002] Many softened water sodium beds use multi-way valves for regeneration, backwashing, forward washing, and water production control, but the multi-way valve is expensive and is an integral structure. If the multi-way valve fails, the entire multi-way valve needs to be scrapped and replaced , therefore, the replacement cost is also high. The softened water sodium bed also uses a control cabinet to control multiple electric valves to control the operation process of the sodium bed, but the electric valves are also prone to failure and require power. Contents of the invention [0003] The object of the present invention is to provide an operation control device, a control method and a fault judgment method of a softened water sodiu...
