Take you to understand how to deal with excessive temperature in the exhaust pipe of a screw freezer
Once the exhaust pipe temperature of the refrigeration compressor of a screw freezer is too high, it will immediately cause the lubricating grease and its refrigerant to undergo decomposition reactions under the catalytic reaction of metal materials. When applied, it will also be converted into acid chemicals, mineral acid carbon, and water that are harmful to the refrigeration compressor. -
The treatment method for damaged load of air-cooled refrigerators: Firstly, it is necessary to confirm whether the compressor load is burned or the components are worn out. If so, it will inevitably cause pollution to the refrigerant system, such as residual refrigerant oil remaining in the pipeline after carbonization, and drying filters absorbing a large amount of water. So, if there is a compressor burning, first analyze the cause of the compressor burning: whether it is a temperature control quality problem such as the contactor and overload device inside the control box; Is it a set value change or adjustment error; Is it due to unstable power supply voltage; Whether the operator operates in the normal order, etc.

There are four reasons for the "three-phase power failure" of the screw chiller: the power supply is not connected, the fuse is blown, the power voltage is unstable or the phase sequence is incorrect, and the transformer is damaged. The troubleshooting methods and their solutions are as follows:1. We need to first investigate the situation where the workshop is out of power and the power supply is not properly plugged in. This usually indicates that other equipment in the workshop is not working, or the power plug of the screw chiller is not properly plugged in, causing the equipment to not be powered on, resulting in a three-phase power failure.

Energy conservation and environmental protection are an important theme in today's era. Many advocates for green travel, resource conservation, especially in industrial areas. How do refrigeration manufacturers advocate for users to reduce the cost of chillers and save resources? This should start from its energy consumption aspect, such as the energy consumption problem of the ice water machine, mainly observing whether there are abnormalities in the unit, or talking about the problem of high or low operating power of the unit. Dalian Aode Air Conditioning Group would like to share with you

During the production process, due to the continuous generation of heat from machinery, molds, and industrial reactions, product quality is unstable when the temperature exceeds the tolerance of the material. For example, in the production of plastic products and electroplating, the cooling time accounts for more than 80% of the entire cycle, and the importance of reducing the cooling time can be seen from this.

1、 Common auxiliary accessories for low-temperature water chillers1. Water flow switchThe water flow switch is used for control or cutoff protection of fluid flow in the pipeline. When the fluid flow reaches the set value, the switch automatically cuts off (or turns on) the circuit.2. Pressure controller
