Sensor faucet water poor repair skills

Nowadays, many sensory taps are used in public places and homes. However, due to the frequent frequency of daily use, sensor taps often cause problems and affect daily life. The following Xiao Bian will explain to you about the method of cleaning and maintenance of the sensor faucet and solutions to common problems. Let's take a look.

Nowadays, whether it is a foreign sensor faucet brand or a domestic sensor faucet brand, its working principle is much the same. Its core components are infrared sensing probes and electromagnetic valve coils. Common faults and maintenance methods are as follows:

1, sensor faucet no water: first determine whether the power supply is normal, the current domestic main power supply for the exchange of 220V transformer 12V and 6V; DC 6V (fourth or fifth alkaline batteries, four) and DC 3V (two quarters seven No. 5 or No. 5 alkaline batteries). Check whether there is any indicator light by hand in front of the infrared window. The infrared window of part of the sensor faucet brand is controlled by a single-chip microcomputer, and the power indicator is in the water control part (installed below the basin). In response, it is initially determined that the sensing part is faulty and the infrared sensor can be replaced. In this case, it is recommended that the user cannot judge the fault. If there is any other normal sensor faucet, the elimination method can be used to insert the infrared part of the plug into the faulty part. The water control part of the faucet makes it easy to judge whether it is a malfunction of the induction part or a malfunction of the solenoid valve of the water control part, and at the same time, it is to be noted whether all plugs have no possibility of poor contact or moisture.

2. The sensor faucet cannot hold water: Excluding foreign matter before the sensing window (the principle of the sensor is as long as the object responds within the infrared sensing distance range) and the indicator is normal, check whether the water inlet filter of the water control part is If there is any blockage of sediment or other debris, please clean it; if it fails to solve the problem, disassemble the solenoid valve and clean the valve core, spring, diaphragm, etc. of the coil, and then put it back in as it is. If not, stop the water. Explain that the solenoid valve is broken and replace the new solenoid valve part. There is an experience on this side. If you can't hold the water, you can feel the water. If you find that the amount of water is getting larger, you can't keep the water after you leave the hand, but the water volume is smaller than when you use it. This shows that the solenoid valve is not faulty. Only need to clean the solenoid valve according to the above method and it can be used normally.

3, sensor out of the small amount of water: on the one hand to see if the water pressure and the pipe itself is small, on the other hand check the water control part of the inlet side of the filter if there is an impurity plug, but also on the one hand consider the use of PPR pipe today, part During the construction of the project, the pipeline joints are hot-melted. It is not ruled out that the hot-melting will deform the pipes and the amount of water passing through the pipes will become smaller.
