Analysis of common
dental chair problems and troubleshooting methods are necessary to ensure normal operation of the dental clinic. If there is a problem with the dental chair, it can affect the patient's experience and treatment results. By analyzing and troubleshooting common problems, chair problems can be repaired in time to ensure a smooth and safe patient visit. Additionally, regular inspection and maintenance of your dental chair can extend its lifespan and reduce repair costs. Therefore, it is very necessary for dental clinics to analyze and troubleshoot common problems with dental chairs. The following is an analysis of some common dental problems and how to troubleshoot them:
1. The strong and weak suction does not work, and the weak suction becomes ineffective after being used for a period of time.
That may exist:
1. The pipeline connection is incorrect;
2. The pipe is blocked by dirt;
4. The weak suction cup is clogged;
5. The weak suction main valve is blocked by dirt;
6. Poor water quality leads to pipe blockage;
Troubleshooting methods: Replace broken parts, check and repair the lines; clean the weak suction main valve; it is recommended that users clean the dirt collecting cup frequently, install it back after cleaning, and keep the pipe unobstructed.
2. The cold light does not light up or other problems occur
That may exist:
1. The light bulb is burned out;
2. The plug contact is poor and the connector is loose;
3. The public line does not penetrate the controlled relay;
4. The internal wires at the movable connection are twisted (do not lift the balance arm);
5. The reflective film of the cold light lamp falls off;
3. The motor of the dental chair does not work when the button is clicked.
1. Check whether the emergency stop switch is pressed;
2. Check whether the limit switch is normal;
3. Check whether the power cord, motor cord, and key board connection cord of the treatment board are connected properly;
4. The hot water cup cannot be heated or the water temperature is too high
That may exist:
1. The power supply or circuit is abnormal;
2. The public line of the hot water cup temperature control line is wrongly connected.
3. The heating rod of the thermostat or hot water cup is broken:
4. The control mask is broken;
5. The relay controlling the hot water cup on the treatment board does not work;
6. The temperature sensor is out of control or the control is insensitive;
5. There is a problem with water vapor during operation of the mobile phone.
1. Pipeline problems;
2. Check whether the air pressure gauge of the air filter pressure reducing valve reaches six kilograms;
3. Check whether the water filter air is blocked by dirt, and if so, clean the filter;
4. Check whether the water source switching position at the bottom of the side box is reversely connected;
5. Check whether the foot switch has poor contact.
6. Pipeline problems
1. If the equipment is used for a long time, friction or extrusion will cause the water and air pipes or mobile phone pipes to burst, disconnect and harden (note: mobile phone cleaning agents will cause the outer pipe of the mobile phone to harden);
2. The pipeline is blocked by dirt and should be cleaned regularly;
3. If the water outlet is not smooth, check whether the drainage pipe is twisted or flat;
4. If the pipes are leaking, check the leaking areas and replace them;
5. If the pipe interface is not tight or loose, it should be reconnected firmly.
7. Solenoid valve problem
1. The solenoid valve is aging and leaking water and air due to long use;
2. The inlet and outlet nozzles are connected incorrectly;
3. The solenoid valve interface is not firm, causing water and air leakage;
4. Solenoid valve quality issues;
5. Poor water quality causes the solenoid valve to become clogged.
8. Circuit board problem
1. Short circuit of circuit board:
(1) Plug in the wrong pair;
(2) Caused by the residue of long-term discharge in wet parts of the circuit board;
(3) The screws on the wiring strip are loose and cause a short circuit:
2. The plug is not tight, loose or oxidized, causing the circuit to not work properly.
9. Water bottle problem
1. Due to the broken pressure reducing valve of the two kilograms, the air pressure in the bottle was too high and it burst;
2. Add non-distilled water to the bottle;
3. The waterway is blocked, resulting in poor water flow;
4. Quality problems lead to poor pressure resistance of water storage bottles;
The above is the analysis and treatment of some common problems with
dental chairs. I hope it can help everyone. Next, we will continue to update some content related to dental chairs.
