　　Six, other matters needing attention

　　Understand product certification: ensure that the selected generator sets meet the relevant standards and certification requirements of the country or industry.

　　Considering the demand: If the ship has special electricity demand or space limitation, it can communicate with the manufacturer for production to meet the actual demand.

　　To sum up, when choosing a marine generator set manufacturer, we need to comprehensively consider the brand and configuration, quality and performance, after-sales service, price and cost performance, strength and reputation of the manufacturer and other matters needing attention. Through a comprehensive evaluation of these factors, we can buy a generator set with good quality and meet the demand, which will provide a strong guarantee for the normal operation of the ship.

　　When marine diesel generator sets are used in different seasons, the following aspects should be paid attention to to to ensure their stable operation and prolong their service time:So we can draw a preliminary conclusion, boat generator It is helpful to the needs of the industry market and social development. https://usrpower.com/product/usr-pgm-marine-generator-jec60-6kva/

　　A, marine diesel generator set preparation before the season.

　　Sanitary cleaning of marine diesel generator set;

　　Remove the insulation blanket (if applicable) and thoroughly clean the generator set, including cleaning up dirt, sundries, grease, etc.

　　In the process of cleaning, pay attention to check loose nuts, rivets and appearance defects, and replace and repair them in time.

　　Check and change the oil:

　　According to the requirements of the instruction manual of the generator set, select the engine oil suitable for the current season.

　　Drain the old oil and replace it with new oil and oil filter.

　　Check and replace the third filter of marine diesel generator set;

　　Air filter, diesel filter and oil filter (referred to as “three filters” for short) are important parts of the generator set and need to be inspected and replaced regularly.

　　Paper filter may not fully recover its performance after cleaning, so it is recommended to replace it with a new one. Metal filter screen and filter element can be cleaned with clean oil, brush or air cylinder, but not with fire.

　　Check the cooling system:

　　Check the level and quality of coolant and replace it if necessary.

　　Clean the scale and sediment in the cooling system to ensure good cooling effect.

　　Second, the marine diesel generator set in season when the operation of the matters needing attention

　　Adjust the oil indicator:

　　For diesel engines equipped with “winter and summer” rotation indicators, the arrow of the indicator should be rotated to the word “summer” to realize large oil circulation, so as to reduce the pressure drop and parts wear caused by excessive oil temperature.

　　Use the right fuel:

　　According to the seasonal changes, choose the fuel suitable for the current temperature. When the temperature is high in summer, low viscosity fuel such as No.0 diesel can be used to reduce fuel consumption and carbon deposition.

　　Start and run the check:

　　Before starting the marine diesel generator set, check whether the liquid levels of fuel, lubricating oil and coolant are normal.

　　After start-up, observe the operating conditions of the generator set, such as whether the parameters such as voltage, frequency, oil temperature and water temperature are within the normal range.

　　If any abnormality is found, stop the machine immediately to check and troubleshoot.

　　Three, marine diesel generator set after the season maintenance.

　　Regular inspection and maintenance:

　　According to the usage of the generator set, check and maintain the plan regularly.

　　Check whether cables and connectors are fastened and reliable, check brushes and carbon deposits, and make necessary cleaning and replacement.

　　Storage management:

　　If the generator is not used for a long time, it should be stored in a dry, ventilated and dust-free environment to avoid direct sunlight and humidity.

　　Close the fuel valve and cooling water valve, remove the battery and keep it properly.

　　Recording and feedback:

　　Record the usage and maintenance records of the generator set, so as to find and solve problems in time.

　　If the generator set is found to be faulty or abnormal, it should be stopped in time and seek the help of professionals.

　　To sum up, marine diesel generator sets need to pay attention to many aspects when they are used in different seasons, including preparations before changing seasons, operational precautions during changing seasons and maintenance after changing seasons. Through inspection and maintenance, it can be ensured that the generator set can run stably and reliably in an emergency.

　　Whether in cold winter or hot summer, air conditioning is an essential household appliance in our home, especially now that people’s living standards have improved, air conditioning has entered thousands of households. Many owners think that choosing air conditioning is the most important thing. I don’t know if it is familiar, but the placement of air conditioning is even more difficult. If it is not in the right position, it will bring trouble to our lives. Many people don’t know the secret of air conditioning placement. Come and have a look with Xiaobian.In addition to these aspects, industrial cooling systems The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

　　Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

　　Where are the air conditioners placed?

　　(1) How to place the air conditioner in the living room?

　　1. Air-conditioning is a kind of fast-running electrical appliance, so it will transfer the air flow from the outside to the home, such as the main disease in the southwest. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year. Correction method: use a small fan to change the wind direction opposite the air conditioner. In addition, if you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

　　2. The most taboo of the air conditioner outlet is to blow to the financial position, and take away the wealth at home together with the cold wind, and the door at home is the main wealth. Therefore, if the air conditioner directly faces the door, it will not only drain the wealth, but also symbolize the popularity. It means that the home is not warm. Correction method: hang a glass screen or cloth curtain at the entrance to solve it.

　　3. The air outlet of the air conditioner directly blows the main chair in the living room (that is, the sofa where three people sit), so that the face sitting here is blown very uncomfortable, which means that the backer is unstable and affects the work and career fortune. Correction: Let the air outlet of the air conditioner come from the side, or move the position of the main sofa.

　　Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

　　(2) How to place the air conditioner in the bedroom?

　　1. Air-conditioning often emits a certain amount of heat during refrigeration, so it must be installed far away from other electrical appliances and avoid being installed in corners, which can make the air-conditioning dissipate heat as soon as possible, ensure that it is not damaged, and prolong its service life.

　　2. The air conditioner is installed at a certain distance from the bed. If it is facing the bed or too close to the bed, it will easily lead to the user catching a cold or catching a cold, which will adversely affect people’s health. Therefore, everyone needs to pay special attention to this when installing the air conditioner.

　　Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

　　3. Air conditioning is installed in the bedroom in the northeast direction, because the radiation in this direction will be relatively small, so that the harm to the human body can be reduced to. In real life, many owners will ignore this problem, which is actually a very serious misunderstanding.

　　4. The height of the air conditioner installed in the bedroom is very elegant. It is not appropriate to be too high or too low. It is recommended that it be higher than one meter and lower than two meters. This height is the most suitable, and its use effect will be in a new state, and it is more convenient for daily use.

　　Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

　　What are the precautions for air conditioning placement?

　　1, kitchen air conditioning moving stove fire

　　It is the place where the whole family can fill their stomachs without installing a kitchen stove. If the air conditioner directly touches the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the occupants. In addition, the stove fire is also representative, so it has a great influence on the couple’s sexual life. Try not to install air conditioning in the kitchen, but if you must, try to blow the wind towards the ceiling or sideways.

　　2, the dining room air conditioning dirty food

　　Blowing the dining table directly is a big no-no, it will inevitably accumulate dust if the air conditioner blows the dining table directly, so it is very likely that the dust will fall into the hot food with the wind, and of course it is easier to cool the delicious meals on the table. Theoretically speaking, eating “dirty rice and cold dishes” for a long time will lead to the hidden worry of being defeated, so the air conditioner in the dining room should not be above or near the dining table.

　　Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

　　3, bedroom air conditioning to prevent discomfort

　　When people who use the air conditioner evenly to eliminate evil spirits sleep, the pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly on the human body, it will not only make the body uncomfortable and catch a cold, but also attract evil spirits more easily. Therefore, the air outlet will be raised upwards, or the windows in the room will be slightly opened to even the cold air coming straight.

　　4. Air conditioning in the study transports energy

　　Wenchang’s good luck comes to the air conditioner to make people cool, so it has the function of condensing thinking and improving reading concentration. If the air conditioner in the study can be moved to the north and the energy of air conditioning operation can be used, it will drive Wenchang’s good luck and be beneficial to candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

　　Xiaobian will introduce the relevant information about the placement of air conditioners here for everyone. The placement of air conditioners directly affects our daily life and fortune. If you are also worried about the placement of air conditioners, you may wish to refer to the suggestions in the article and choose the optimal scheme, so as to feel the comfort brought by air conditioners to a certain extent without affecting human health. I hope that the knowledge summarized by Xiaobian can bring you help.
