What happens when the cold storage stops a few seconds after it is activated

Under normal circumstances, the situation that stops after a few seconds of starting is the compressor high and low pressure protection, please check yoursElectrical boxIf there is anything to show, follow the instructions to check. It's best to have it repaired by a professional!

In this case, the motor protector is acting, and the lack of phase is not necessarily the lack of phase, which depends on the type of motor protector, and some motor protectors are three-phase electric.

Unbalance will also show the lack of phase, measure whether the power supply voltage is three-phase balanced, and then detect the three-phase power supply.

Current, if the current is not very large, the compressor should be fine! The focus is on the motor protector, the cheap electric control cabinet on the market is very unreliable!

Cold storage must have a person responsible for management, management personnel must understand the working principle and operation method of cold storage. This requires that the cold storage operation and maintenance personnel must undergo technical training and safety technology education, understand the basic structure of the equipment, and be proficient in operating procedures.

And operate in strict accordance with the operating procedures.

When starting the cold storage, you need to turn on the power switch first to check the water circulation.

Whether the pump indicator light and the cold storage normal operation indicator light are on, and then set the cold storage temperature. Observe the air cooler in the cold room.

It should start running, and after a delay of 3 minutes, the refrigeration indicator on the microcomputer temperature controller will light up and the compressor will start working.

1. Control system failure.

The control system of the cold storage is one of the important parts to ensure its normal operation. If the control system fails, it will cause the cold storage to not function properly. Stopping the cold room immediately after starting may be caused by a malfunction of the control system.

Common control system faults include sensor faults, switching power supply faults, controller faults, etc. If this is the case, all electronic components in the control system can be checked and the faulty component can be replaced.

Second, the compressor problem.

The compressor of the cold store is one of the key components of its proper operation. If there is a problem with the compressor, it will cause the cold storage to not function properly. Stopping the cold storage immediately after starting can also be caused by a problem with the compressor.

Common compressor problems include motor failure, loose drive belt, tripping overload protector, etc. If this is the case, all relevant parts of the compressor need to be inspected and repaired or replaced accordingly.

3. Electrical problems.

The electrical system of the cold storage is also one of the key components of its proper functioning. If there is a problem with the electrical system, it will cause the cold storage to not function properly. Stopping the cold room immediately after starting can also be caused by an electrical problem.

Common electrical problems include loose wiring, tripping circuit breakers, blown fuses, etc. If this is the case, all the electrical parts of the cold room can be inspected, the problem can be found, and the corresponding repair or replacement can be carried out.

To sum up, the cold storage stops immediately after starting, which may be caused by control system failure, compressor problems, electrical problems, etc. If this happens to you, you can fix the problem by checking the electrical components, compressor components, and all the electronic components in the control system. If it can't be solved, it is recommended to contact a professional cold storage maintenance company to solve the problem.

Hello! I am from Shanghai Muyou cold storage, under normal circumstances, the situation that stops after a few seconds of start is the high and low pressure protection of the compressor, please check if your electric box is displayed, and check according to the manual. It's best to have it repaired by a professional!

It is a lack of phase, and one or two phases of the three-phase electricity have no electricity.

This situation is the motor protector action, showing the lack of phase is not necessarily the lack of phase, this depends on the type of motor protector, some motor protector three-phase electrical unbalance will also show the lack of phase, measure whether the power supply voltage is three-phase balanced, and then detect the three-phase power supply current, if the current is not very large, the compressor is basically fine, focus on the motor protector.

Equipment composition. Generally, the cold storage is mostly cooled by the refrigeration machine, which uses the liquid (ammonia or freon) with a very low gasification temperature as the coolant, so that it can evaporate under the conditions of low pressure and mechanical control, absorb the heat in the storage, so as to achieve the purpose of cooling and cooling.

The most commonly used is the compression refrigerator, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe, etc. According to the way of evaporation pipe device, it can be divided into two types: direct cooling and indirect cooling. Direct coolingThe evaporation tube is installed in the refrigerated warehouse, and when the liquid coolant passes through the evaporation tube, it directly absorbs the heat in the warehouse and cools down.

It's a circuit thing. Take a closer look at the line to see if there is any false connection.

It is a lack of phase, in the three-phase electricity, one or two phases have no electricity.

Hello, the reason why the cold storage will stop immediately after turning on If your temperature is normal, this is a normal phenomenon, the working principle of the compressor is to start --- stop --- like this, if he has been running, can you stand it? Isn't it easy to break? If the temperature is too fast, it is possible that the insulation layer is not done well, resulting in too frequent compressor starting1. Overload, you can reduce the electricity load when overloaded, or stagger the power consumption time of high-power equipment.

2. Leakage, leakage is not easy to check, when there is no special equipment, you can only try one by one, to see which equipment to use when you love to trip, and there is also the aging of the line will also trip. 3. When there is a short circuit, it will trip immediately, 4. The defrosting circuit will leakage. Remove the omission and give it a try.

5. Control the switch, use the universal meter to measure the line of the cold storage, if there is no short circuit or leakage, it is an instantaneous current that is too large, change it, and the control switch is so sleepy. 6. Trip when the power is on, check the control box. 7. If the compressor trips instantaneously when it starts, check the internal fan and the external unit.

If the internal fan is easy to check, see if the inner fan is rotated, and the external fan. 8. Energized parts: cooling fan, compressor, solenoid valve, check by yourself.

I hope my answer is helpful to you, and I wish you good health and a happy mood!

What is the fault of the cold storage when it starts up in a few seconds? Hello, I am happy to answer for you<> pro-cold storage starts a few seconds and stops as follows: it may be that the power supply voltage is too low and the voltage is unstable:

Troubleshooting method: Wait for the power supply voltage to return to normal before turning on the refrigerator or using the AC regulated power supply. The condenser has a poor heat dissipation effect:

The poor heat dissipation effect of the condenser will reduce the cooling capacity of the compressor, which will cause the compressor to overload the operation, resulting in a great increase in the operating current, and the overcurrent protection relay will change the field action and cut off the circuit, and the compressor will stop running. When the temperature of the protection relay drops to the reset temperature, the contacts are closed again and the compressor runs again, causing the compressor to start and stop frequently. It may be that the supply voltage is too low and the voltage is unstable:

Do you have any other questions?

Summary. Hello dear, glad you have a problem, there are the following failures that may cause:

In addition to the unstable power supply voltage, excessive fluctuation range, excessive heat load, poor heat dissipation, and improper matching of the starter or protector with the compressor, the compressor operating current is too large.

What's going on with my freezer compressor stopping and starting at a while?

Dear, hello Kai talk, I'm glad to answer your question early, Zaosunque has the following faults that may cause: unstable power supply voltage, too large fluctuation range, excessive heat load, poor heat dissipation, improper matching of the starter or protector and the compressor, that is, the compressor operating current is too large.

The insulation of the motor winding of the freezer pressure reed reducer is partially damaged, resulting in a turn-short circuit and an increase in current. The compressor moving pair is worn, which destroys the smoothness of the friction surface, causes the shaft power of the compressor to increase, and the running current increases skillfully, but it has not yet reached the degree of holding the shaft and supporting the width of this cylinder, so that the compressor can not start running.

Hello dear, I wish you a happy life and all the best! I hope mine is helpful to you

The cold storage stopped a few seconds after it was started, and the fault showed that there was a missing item.

Hello, the problem received by the teacher is: The cold storage stopped just a few seconds after it was started, and the fault showed that there was a missing item. : The cold storage stopped just a few seconds after it was started, and the fault showed that the missing item was:

If your rough voltive temperature is normal, this is a normal phenomenon, the working principle of the hall compressor is to start --- stop --- like this, if he has been running, ** can it be bearable? Why? If the temperature warms up quickly, it is possible that the insulation layer is not well prepared, causing the compressor to start too frequently.
