According to different hammer head shapes, hammers can be divided into ball pein hammers, sledge hammers, etc. According to different hammer head materials, they can be divided into carbon steel hammers, wood hammers rubber hammers, plastic hammers.
The specifications of the hammer are generally expressed by its mass, and commonly used are 0.25kg, 0.5kg and lkg.
Daily maintenance and precautions for water coolers
Author: Beijing Hengxing and Technology Co., Ltd. Source: http: //
Beijing Hengxinghe Technology Co., Ltd. is a large-scale foreign-owned enterprise specializing in R&D, production and sales of industrial refrigeration and refrigeration equipment. The products are exported to all over the world and are suppliers of industrial refrigeration and refrigeration equipment in more than 20 countries and regions. The market share of products has been ranked among the top in the domestic industry for many years.
As a large supplier of industrial refrigeration and refrigeration equipment, at this time, many companies are carefully purchasing industrial refrigeration and refrigeration equipment suitable for their own use. Today, let Beijing Hengxing Technology Co., Ltd. explain to you what is a water cooler? What are its daily maintenance and precautions?
The water cooler is a common name for chillers. It mainly reduces the refrigerant to a temperature by means of manual cooling, and uses refrigerant to cool other things or use them directly. The term water cooler is rarely used in the industry. It is well known than the name of the chiller.
Maintenance and maintenance of water cooler (chiller):
1. Clean the condenser and evaporator regularly to keep the whole machine running smoothly;
2. Keep the cooling tower clean and clean regularly. There should be no debris or other obstacles in the cooling tower to avoid injury.
3. Air-cooled freezer keep the surface of the radiator clean and clean it regularly to maintain good performance.
Water cooler (chiller) operation precautions:
1. The chilled water Pump shall not operate without water in the water tank;
2. Operate the switch as much as possible to avoid continuous switching;
3. When the temperature of the frozen water reaches the set temperature, the compressor will automatically stop running, which is a normal phenomenon;
4. The temperature switch should be avoided to be set below 5 °C to prevent the evaporator from freezing; (except for low temperature freezer).
5. To ensure the best cooling of the water cooler (chiller), clean the condenser and evaporator and water filter regularly.
The following are water coolers (chillers), etc., common problem handling methods:
1. Poor heat dissipation and treatment method: When the condenser heat dissipation is poor, the compressor efficiency is low and the running current is increased. When the air-cooled high pressure rises to 24kg/cm2, the water-cooled high pressure rises to 20kg/cm2, and the compressor is subjected to high pressure. The switch protection trips, the compressor stops running, the heat dissipation is poor, the high voltage is overloaded and the fault code or fault indication is displayed. At this time, please check whether the cooling tower circulating water is normal, the cooling water temperature is too high, the cooling tower fan water pump is running, the cooling water valve is Open completely (air-cooled type, please check whether the radiator is dirty), after normal, press the reset button (REST) ​​or shut down to restart. If high voltage overload occurs frequently, please arrange to clean the condenser as soon as possible.
2. The refrigerant is insufficient for low pressure treatment:
a. When the water temperature is above 5 °C, when the pressure of the low pressure gauge is lower than 2 kg/cm2, it means that the refrigerant is insufficient. First, the place where the refrigerant is leaked is subjected to trapping treatment, and then the dry filter is replaced and the vacuum is refilled to fill the appropriate refrigerant.
b. When it is found that the leaking refrigerant is partially immersed in water, stop the operation of the freezer immediately, and quickly remove the water from the water tank. Inform the company to dispatch personnel to handle the repair as soon as possible to prevent the compressor from inhaling water into the system and causing more serious damage.
The above is the content of the water cooler that Beijing Hengxing and Technology Co., Ltd. explained to you. I hope that this short article will bring you some benefits.
