5. Common faults and troubleshooting methods of cold storage?

Faults and troubleshooting methods are as follows:

1. Poor cooling effect

This is one of the common faults in cold storage, which may be caused by blocked cooling pipes, improper valve adjustment, poor cold air flow, etc. To solve this problem, the following maintenance methods can be carried out:

1. Clean or replace the blocked cooling pipe: Usually the cooler in the cold storage will be blocked due to long-term use, affecting the cooling effect. It is necessary to purge the air in the air duct after a power outage, and then disassemble the cooler for cleaning or replacement.

2. Adjust the valve: If the valve position is found to be out of balance, it should be readjusted to ensure the cooling effect. Tighten the air inlet valve to ensure normal air volume. At the same time, due to the existence of negative pressure, a small gap needs to be left in the cargo room door.

3. Enhance the smooth flow of air conditioning: Check whether the air duct is smooth and clear it if there is any blockage. At the same time, ensure that the parts are not damaged and the interfaces are tight to prevent air leakage.

2. The compressor is working abnormally

The compressor in the cold storage is an important and convenient equipment. If the following abnormalities occur, it should be repaired immediately:

1. The compressor noise becomes louder: Check whether the cold storage compressor is loose and tighten it if necessary The power must also be turned off. If there is no problem, you need to check whether the compressor parts have poor friction.

2. Compressor overheating: Check whether the cold storage compressor is overheating due to insufficient energy dissipation air flow. You can strengthen the air flow, clean the radiator, etc.

3. The compressor cannot start: Check whether the power switch is turned on, and check whether the fuse and wires are damaged. If replacement is required, the power must be turned off and then replaced.

6. High voltage board failure and how to troubleshoot it?

High-voltage board failures include voltage loss, shielding capacitor damage, transformer failure, regulator failure, poor contact of the welding head, etc.

Loss of voltage: Check whether the wire connector is loose. If it is loose, adjust it in time; check whether the insulation resistance is normal; check whether the current regulator and power plug are loose or damaged; check whether the capacitor has leakage.

Damage of the shielding capacitor: Check the health of the shielding capacitor. If it is burned out, replace it with a new one in time.

Transformer failure: Check whether the temperature and sound of the transformer are normal. If there are any abnormalities, the electromagnetic structure of the transformer may be damaged and should be repaired or replaced in time.

Regulator failure: Check whether the temperature of the regulator is normal. If there is any abnormality, check whether the circuit board is damaged. If so, replace it in time.

Poor contact of the welding head: Check whether the welding head on the high-voltage board is loose. If it is loose, re-solder it in time.

7. Timing socket failure and troubleshooting methods?

1.

First check whether each button is abnormal, stuck, etc., and then check whether the main control is working. By debugging each function button, it is found that the display and setting time are all working normally. The only problem is that the settings At a certain time, there is no power output from the socket, let alone turning off the power. This means that the display and main control functions are normal, but the switch is not switched according to the set time, and the power is turned on and off abnormally.

2.

The only way is to disassemble and check.

3.

After disassembling it, first check whether there is any burnt circuit, and none was found through inspection.

4.

At this time, a relay was found. Its working principle is to use the relay to control whether the socket has power or no power output after setting the time. To control the relay's work, it is usually to add a voltage value to the trigger pin to achieve the pass. When the trigger pin meets the open voltage value, the relay trigger pin is triggered to turn on or off. When there is no power or the voltage value does not reach the trigger value, the relay does not work.

8. Classification and troubleshooting methods of gas circuit faults?

The classification and troubleshooting methods are as follows:

1. Gas circuit fault classification:

(1) Gas source failure: insufficient gas source pressure, oil and water impurities in the gas source, gas source pipeline leakage, etc.

(2) Actuator failure: Actuator stuck, poor sealing, wear, aging, etc.

(3. Connection pipeline failure: loose connection pipeline, leaking joints, pipeline wear, etc.

4) Control element failure: control element aging, poor contact damage, etc.

2. Gas circuit troubleshooting method:

(1) Check the air source. Check whether the air source is normal, including whether the air source pressure is sufficient and whether there are oil impurities in the air source, etc.

(2) Check the components: Check whether the actuating components are normal, including whether the components are stuck, whether the seals are good, whether they are worn or old, etc.

(3) Check the connecting pipe: Check whether the connecting pipe is normal, including whether the connecting pipe is loose, whether the joint is leaking, whether it is damaged, etc.

(4) Check the control components: Check whether the control components are normal, including whether the control components are aged, whether the contact is good, whether they are damaged, etc.

As mentioned above, the troubleshooting of gas circuit faults needs to be classified and dealt with according to the specific situation, and each part needs to be carefully inspected to ensure the normal operation of the gas circuit system.

9. Brother computer flat car fault code and troubleshooting?

The E-07 error is that the memory module is damaged. Common faults of computer sewing machines include: hardware failure: damaged memory module, damaged motherboard components, and damaged hard disk.

Software failure: system crash, Trojan virus, driver mismatch.

Solution: First check whether the CPU fan of the power supply is rotating and whether the motherboard indicator light is on, and make sure that the power supply is dry and the circuit is powered on. It may be a problem with the memory module. Pull it out and wipe the gold finger part and try again. 10. What are the causes and troubleshooting methods of the SRS fault light?

1. There are foreign objects around the airbag sensor connection harness, especially metal filings, which can easily cause a short circuit, causing a false alarm of the fault light;

2. The SRS fault light turning on may also be caused by an error in the ECU sensing data in the car;

3. The SRS fault light is on for no reason. It may also be that the vehicle has been parked in a humid environment for a long time, or the connection interface is wet due to a short circuit during the car wash. There are many reasons for the SRS light to come on. In some airbag systems, after the ignition switch is turned on and the engine is started, the indicator light will glow continuously for about 5 seconds and then go out automatically. This is a normal phenomenon. If it stays on, it means there is a problem with the car's airbag. In order to ensure driving safety, you must drive at a slow speed and perform maintenance in time to eliminate the SRS fault light; when the battery voltage is too low, it will also cause the SRS indicator light to light up. If the generator can be charged normally, after the voltage returns to normal, The SRS indicator light will turn off automatically.
