FleckFLECKThe control valve is the core component of the water softener, consisting of a multi-way valve and a regeneration control device. Now let's talk about FleckFLECKProblems that often occur during the operation of control valves.

1. The soft water output is substandard

The water supply pressure of the system does not meet the requirements FLECKThe water softener requires a water supply pressure of2～6Kg/cm2Between them, when the water supply pressure is less than1.75 Kg/cm2When the flow rate of the water jet used for salt suction is too low, it cannot generate sufficient negative pressure to draw in brine, which is manifested as insufficient salt suction (there is still saturated brine remaining 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 than6 Kg/cm2When the pressure resistance range of the fiberglass reinforced plastic soft water tank is exceeded, it is easy to cause leakage of the soft water tank, sealing rings at various parts, pipes and connection points, resin leakage and even equipment rupture and damage. For the vast majority of users, municipal tap water is generally used as the water supply for the water softener, and the water supply pressure should meet the requirements of the equipment. For users with special water supply, this point needs to be confirmed before the system installation. For systems that do not meet the conditions, the solution should be determined in combination with the on-site situation.

2. Poor salt absorption or no salt absorption

In terms of equipment installation, since the length of the pipes needs to be determined on site and the appropriate length needs to be cut manually, a common problem that occurs on site is that the pipe length is not cut appropriately. If the pipe is too long, the soft water control head cannot be strictly sealed with the tank, resulting in water leakage at the tank opening. If the pipe is too short, it will cause water near the resin layer not to pass through, commonly known as water flow short circuit (a sound of water flow can be heard at the tank opening during equipment operation), and the hardness of the effluent water will exceed the standard. Before installing the pipe, it is necessary to position it first. Then, measure the required length by referring to the depth of screwing in the control head. Cut it flat with a hacksaw. The cross-section should be even, smooth and free of burrs. For soft water tanks with diameters exceeding800mmThe equipment, the lower water distributor is of the main pipe and branch pipe type. The installation of the branch pipes is also carried out on site. It is required that the branch pipes must be tightened to prevent them from falling off under the impact of water flow and causing resin leakage.

Three. The regeneration process does not absorb salt or absorbs salt very slowly

Low water supply pressure, clogged brine filter, clogged brine suction pipe, and clogged water ejector are several possible reasons for poor salt suction during regeneration. The inspection methods are as follows in sequence: First, check the pressure gauge on the water inlet pipe to confirm that the inlet water pressure is qualified. Then, inspect the salt suction pipe (transparent plastic pipe) to see if there is any blockage. Next, unscrew the salt water filter, disassemble it and rinse it with clean tap water. If the problem still cannot be solved, you need to disassemble the upper sealing cover of the water jet and rinse it with clean tap water. Generally, the above steps can solve the problem. Note: When installing the upper sealing cover of the water ejector, it must be done when the water ejector is fully filled with water to avoid air inside the water ejector causing air resistance. If the salt suction pipeline frequently gets clogged, it indicates that the content of insoluble impurities in the regeneration salt is too high. The general requirement for regeneration salt is industrial salt without iodine, and the fewer impurities in the salt, the better.

Iv. Resin leakage

It occurs during the water production or regeneration process of the water softenerIon exchangeResin leakage (resin enters the soft water tank. Or if it flows out along with the sewage, it is called resin leakage. The common reasons for resin leakage during water production are pipe rupture, the detachment or rupture of the lower water distributor, and a large amount of resin entering the soft water tank. It is easy to find out by disassembling the resin tank and pulling out the pipe for inspection. If there is any damage, the damaged part can be replaced. The main reasons for resin leakage during the regeneration process (resin flowing out with the blowdown water) are the rupture of the upper water distributor and the excessively high pressure and fast flow rate of the backwash water. Under the condition that the upper water distributor is not damaged, reducing the flow rate of the backwash water can solve the problem.

Five. Insufficient periodic output or rapid output attenuation

The main reason for insufficient periodic output or rapid decline in periodic output of a water softener is "resin poisoning". Common causes of poisoning include the use of iodized salt during regeneration or high iron content in the feed water (this problem is more likely to occur at the end of municipal water supply networks or in users who use groundwater). When resin poisoning occurs, the first step is to stop using iodized salt. The groundwater for high-speed rail should be pre-treated to remove iron. For the already poisoned resin, regeneration treatment should be carried out. The regeneration treatment of the poisoned resin should be conducted by dedicated personnel.

Six. The water softener cannot regenerate automatically

The common reason for the water softener not regenerating automatically is the damage of the flowmeter that controls regeneration. The main cause of the flowmeter damage is improper operation. When setting the flow disk and the regeneration program time, if the flow wire is not unpulled, it is very easy to cause damage to the variable speed gear set in the flowmeter. This point must be noted by everyone during use. When a flowmeter is damaged, it can only be replaced. If the manual flowmeter wire can drive the regeneration program but the regeneration cannot continue automatically, it indicates that there is a fault in the circuit or motor of the water softener control head. It should be inspected or the parts replaced by a dedicated maintenance person.

Seven. The regeneration process is disordered and cannot regenerate well

The regeneration program is in disorder and the equipment cannot operate The main reason for the disorder of the regeneration program in a normally debugged water softener is caused by a power outage.FLECKRequirements for water softeners24There is no power outage for hours. Generally speaking, a power outage during the normal water production process of a water softener driven by a turbine flowmeter has little impact on the equipment. However, if a power outage occurs when the equipment is in the regeneration state, the regeneration program will become chaotic, and the regeneration program of the control head needs to be readjusted after the power is restored.
