How to clean the cooling system of vertical rubber injection molding machine

The flow rate of the hydraulic cooling channel of the vertical rubber injection molding machine is generally 40L/min, and the barrel is about 20L/min. Because there are too many POM materials, the mold does not require cold water, so how to meet the cooling requirements of the injection molding machine? and Control the cost?

If the 40T machine is only for cooling hydraulic oil, you need to buy a plastic bucket and use an air-conditioning pump to pump water to cool it. The air-conditioning pump must be bought. Generally speaking, the electricity consumption is equivalent to a 100W light bulb, which is very energy-saving.

Compared with other injection molding machines that need to be cooled, the engine may be overheated for a long time and there may be a danger of cylinder explosion. If you want to avoid such bad failures, the radiator must work normally, but the key is to keep the cooling system running normally. Today's engines operate at a higher temperature than in the past, but because of the addition of the emission control system, the radiator, engine compartment and grille area have also become smaller.

It is generally recommended that the vertical rubber injection molding machine clean the cooling system once a year to maximize the life of the radiator. First of all, make sure that the engine is in a cooling state and turn off the engine; remove the radiator cover to ensure that the engine is cool; open the drain plug (or water pipe) at the bottom of the radiator to let the coolant flow into the barrel; close the drain plug (or install the water pipe) You can fill the radiator with water; turn on the engine, turn on the heater control system (so that you can operate the heater control valve), so that you can add the cooling system cleaner, empty the engine for 30 minutes; turn off the engine to cool down for 5 minutes, generally you can Drain the liquid in the radiator; close the drain plug, fill the radiator with water and let the engine run for 5 minutes; then refill the compound of 50/50 water and glycol antifreeze/coolant.

Method for distinguishing the quality of aluminum glass folding door

First, look at the materials
The material is the key to aluminum glass folding door. At present, the main aluminum alloy materials are aluminum, glass, hardware and so on. Therefore, choosing aluminum glass folding door mainly depends on its material and accessory material. The wall thickness of the aluminum profile of the color aluminum window should be no less than 1.2mm, and the thickness of the oxide film should reach 10 microns. Tempered glass is better than ordinary glass. If the safety and durability of aluminum glass folding door can be considered, how to distinguish the quality?

Stainless steel hardware accessories are generally better than aluminum accessories, and the pulley is best to use products made of POM material, so the products have higher strength and wear resistance, smooth during use, not easy to damage.

Second, look at the craft

Craft is very important for aluminum glass folding door. The aluminum glass folding door process with fine processing and smooth cutting is naturally very smooth in opening and closing. If the processing is unqualified, there may be problems with the nature of the seal. Not only is the air leaking, but also under the action of strong winds and large external forces, the glass may even burst and fall off, causing loss of property or even injury to the owner.

Third, look at the appearance
The appearance of aluminum glass folding door will also affect the whole decoration effect, so when choosing aluminum glass folding door, the appearance can not be ignored.

Fourth, look at the brand
Brand effect is one of the subjective factors for consumers to consider how to choose aluminum doors and windows. Therefore, consumers can choose some aluminum glass folding door brands with a certain popularity when they choose aluminum glass folding door.

Rapid 3d prototyping technology causes wire breakage

(1) Problems with printed materials

FDM rapid prototyping machine rapid 3d prototyping generally requires the material to be heated and melted, and then the filament is extruded from the nozzle and bonded to the work surface. The temperature resistance strength of different materials is different, and the heating temperature of different 3D printer nozzles is also different, so the appropriate 3D printer consumables should be selected according to the performance of the device. If the quality of the materials used is not good, there will be broken wires.

(2) The problem of the nozzle

3D printer nozzles will also have some clogging problems. In this case, there is no way to discharge normally. Therefore, if the quality of the spray head being used is not close enough, it may cause damage and fail to spin, or the unreasonable internal design is not conducive to threading.



(3) The temperature is too high

The printing time of current rapid 3d prototyping 3D printers is still relatively long. During this process, the temperature will increase. If the equipment is not equipped with a good heat dissipation device, the nozzle will easily cause wire breakage due to overheating.

How to properly clean the infrared thermal imager camera

Some of the electronic products we use every day, such as computers and mobile phones, are dirty and wiped off with a soft cloth or toilet paper. However, for a sophisticated infrared thermal imager camera, it may not be so easy to clean.

1. Preparation of tools for cleaning infrared thermal imager camera
Before cleaning the infrared thermal imager camera, we must first select the auxiliary tools for cleaning, such as warm water, neutral detergent, soft cloth, medical cotton, alcohol, special lens cleaning fluid, acetone and so on.

2. Clean the casing of the infrared thermal imager camera
For the cleaning of the infrared thermal imager camera body shell, we can wipe it with a soft cloth dipped in water. If it is difficult to wipe off the contaminants, you can take a proper amount of cleaning solution for cleaning, then wring out the soft cloth and wipe the thermal imager multiple times. For the case, just try cleaning fluid. This method is also suitable for cleaning some accessories of infrared thermal imager camera. But please be careful not to let the cleaning liquid stay on the charging cable or other key parts of the infrared thermal imager camera, so as not to damage the thermal imager.

3. Clean the infrared lens of infrared thermal imager camera
Because the infrared lens surface of the infrared thermal imager camera has a layer of precision coating, everyone should be very careful when cleaning the infrared lens, and the movement should be gentle, and never use too much force to avoid scratching the lens. In actual operation, a small amount of lens cleaning solution can be gently wiped with medical cotton. After removing contaminants, use a soft cloth to remove the cleaning solution on the lens. Note that the wiped medical cotton cannot be reused. This will cause secondary pollution.

SEVERAL WAYS TO DEAL WITH STICKERS ON THE LIVING ROOM COFFEE TABLE

The newly bought living room coffee table is a good product that has already been made. It is beautiful and elegant. However, if there are some defects on the surface, it is very easy to appear dazzling, and the living room coffee table manufacturer will help you how to deal with this situation.

(1) To deal with the adhesive on the living room coffee table, you can pour a small amount of wind oil on the living room coffee table with traces of the adhesive, and then slowly wipe it with a rag, you can remove it in a while.

(2) I have encountered stickers that stick to the living room coffee table. After the experiment, a simple and easy way is to use the adhesive remover in the car beauty shop to remove the stubborn adhesive. Thinner of gasoline or paint can also be used to remove stickers.

(3) Purchase a bottle of xylene from the decorative materials market, dip a little with a rag, gently wipe the traces of the adhesive, and it can be removed quickly. During the cleaning process, xylene has a pungent odor, remember to ventilate during operation, and it can be eliminated after ventilation.
