On the installation and use of hydraulic oil air-cooled radiators [06-06 10:14]
A. Due to the different working principle and structure of air cooling and traditional water cooling, domestic manufacturers often connect to the system according to the previous water cooling installation method, which is not recommended. Most foreign companies, such as Japan and Germany, use independent circulation cooling methods, so that they are separated from the system and there is no problem of oil leakage. When air cooling is connected to the circuit, it is necessary to install a bypass circuit so that the radiator can be protected in the event of a machine failure, such as the electromagnetic card valve, sudden braking, circuit control failure, etc. The main reason for the radiator burst is that the pressure of oil return pulse rises instantly. In addition, the bypass circuit must be returned to the fuel tank separately. If it is combined with the system return pipe, it is also a failed installation method.
Advantages of hydraulic oil radiator installed with independent circulation cooling method [12-04 15:52]
Now more and more users know the advantages of installing independent circulation cooling method for hydraulic oil radiators, so they give up this method of oil return cooling and choose to adopt independent circulation cooling method. That is because the independent circulation cooling method is adopted, the pressure of the hydraulic oil is relatively low, and the impact of the radiator is relatively weakened, which can effectively extend the service life of the period.
Connection method of installing check valve in air cooler [11-28 09:57]
Heyida staff usually recommend that users install a check valve when using an air cooler. The check valve is mainly used for pressure relief and shunting, so that the liquid or air flow can only flow in one direction instead of the direction control valve. Also called check valve. The check valve is connected in parallel with the air cooler, and it ensures that the check valve can be opened and unloaded preferentially when the pressure is too high or a hydraulic shock occurs. Use hydraulic oil as much as possible, the faster and smoother the return flow, the better the heat dissipation effect.
Can hydraulic oil coolers cool water? [01-02 09:15]
HOBDAR hydraulic oil cooler uses aluminum as the raw material. It is required to ensure that the medium passed through does not cause corrosion to the aluminum. For example: purified water can be passed in after treatment. Tap water is not allowed, because tap water contains acidic substances that can cause corrosion of aluminum, and there are many impurities, which are prone to scaling and block the channels in the cooler.
Reasons for the cooling effect of the air compressor radiator [12-29 09:08]
The air compressor radiator is a very important part of the screw air compressor, which plays a role in cooling the air compressor oil. When the air compressor radiator is used for a long time, the cooling efficiency will decrease and the temperature of the oil will rise, causing the air compressor to trip.
The cooling effect of hydraulic air-cooled radiator will decrease over time? [10-20 09:07]
Maybe some users find that when the hydraulic air-cooled radiator is newly installed, the cooling effect is very good, but after a period of time, the cooling effect is better.
The area where the recommended oil flow and the maximum oil flow of the hydraulic air cooler are purchased [10-12 09:29]
The recommended oil flow is what the name suggests is the oil flow when our Heida cooler advises customers to use a hydraulic air cooler. This recommended oil flow data is the result of our accurate calculation. If the customer's oil flow has been Maintaining the data of our recommended oil flow can well protect the hydraulic air cooler and extend its service life.
Briefly summarize the production process of manufacturing engineering machinery radiators [09-14 08:56]
1. Purchase of raw materials (inspection and screening of a series of raw materials such as aluminum foil, aluminum plate, partitions, seals, grooved aluminum, joints, piping, flanges, etc.); 2. Core assembly (finned fin type, finned cutting, ultrasonic cleaning , Heat exchange unit composition, stacking); 3. Vacuum welding (radiator placed in a vacuum welding furnace for brazing); 4. Assembly welding (assembly welding of heads, piping, support and other accessories); 5. Test pressure Inspection (radiator is placed in a pressure test tank); 6. Surface cleaning, electrostatic spraying; 7. Finished product cleaning, inspection, packaging, and shipment.
Hydraulic air cooler is mainly composed of three parts [09-12 08:28]
1.Hydraulic air cooler-the core of the core heat exchange is the core, which uses vacuum brazing, aluminum as raw material, and plate-fin structure. We often call it aluminum plate-fin heat exchanger. The plate-fin heat exchanger is mainly composed of partitions, fins, seals, and deflectors. Between the two adjacent partitions, a layer of interlayer is formed with fins, deflectors and seals, called a channel. Many of these interlayers are stacked one after the other, and brazed into a whole to form a plate bundle. Supports are formed. Its advantages are: strong reliability, eliminating the possibility of leakage; fins have both heat transfer and support, so high strength; light weight, large heat exchange area, good heat dissipation effect; wide range of applications, can be widely used in gas- Liquid and liquid-liquid heat exchange.
The main reason for oil leakage from air cooler radiator [09-04 08:40]
With the development of the industry, more and more people know the air cooler and use it more and more. However, the use of air coolers by users is not detailed and well understood. The main problems encountered by users when using air coolers are still oil leakage. Everyone is not clear about the oil leakage of air cooler radiators. Here, I will talk about the problem with you.
Which cooling method is the best choice for water-cooled and air-cooled coolers [08-21 10:48]
In hydraulic systems, air-cooled coolers are used more than water-cooled coolers. However, different cooling methods are used in different situations. as follows:
Anti-corrosion pace of hydraulic air cooler [08-07 10:34]
Each cooler has its own advantages and disadvantages, everyone has a little understanding of the signs of corruption, but then we must choose a safe and fair choice to avoid the pace of corruption, and better apply the hydraulic air cooler.
How to arrange the air cooler to achieve the best working effect [08-05 09:41]
How to design the cause of the cooler in the application of the cooler The environment, installation location, ventilation and other issues need to be considered. The principles and tricks of the layout are not explained in detail, so that the cooler can exert the best working effect. Two details must be noted.
The correct installation method of AF series AF0510, AF1025 hydraulic oil cooler [07-11 09:52]
1. It is recommended to use a hose, add a bypass to unload the loop, or use an independent circulation cooling method. 2. The cooler must be placed in a well-ventilated place, and it is easy to clean the dirt on the air inlet side. There must be a space above the radius of the fan blades in front and back to facilitate the air circulation and heat exchange effect.
Why does the hydraulic oil radiator not work properly and the oil temperature is too high? [06-21 14:18]
① The oil temperature is too high due to a blockage in the internal passage of the radiator; ② The dust outside the radiator is too large, which causes the oil temperature to be too high in a timely manner; ③ The radiator fan does not have enough wind to cause the heat to be untimely; ④ The hydraulic oil is not installed properly Failed to pass the radiator; ⑤ The ambient temperature is high, and it can work for a long time in the hot sun.
Inspection method for sealing performance of automobile water tank radiator [06-19 10:34]
Automobile water tank radiator is a kind of radiator equipment used in automobiles. It can effectively bring a large amount of hot air generated during the operation of the automobile to the air, thereby reducing the temperature of the generator and extending the power generation inside the automobile. Machine life. The common fault in radiators of automobile water tanks is generally the problem of water leakage.
Common reasons for the vulnerability of water tank radiator cores [06-17 10:18]
1. The water tank in the radiator is moved backward due to poor fixing; the water tank is incorrectly installed, or the fixing bolts are loose, and the rubber pad fails to cause the water tank to move backward; the engine is improperly installed and moved forward, so that the gap between the water tank and the fan blade is too small.
How to solve the problem when the radiator of the construction machinery water tank leaks? [06-16 08:46]
Several cracks and leaks were found in the water inlet and outlet hoses of the radiator of the water tank. First, find the tape or the cloth coated with soap. Wrap the leaking area of the hose tightly, and wrap some iron wire around it to tighten. The middle tape or cloth can also be replaced with a plastic film. If the cracked place is not tightly packed, use a plastic tube with the same caliber and hose size as the rubber tube.
What to do if the oil temperature is too high? Heyida hydraulic oil radiator effectively reduces oil temperature [06-15 09:40]
1. Where conditions permit in all aspects, install a hydraulic oil radiator on the oil return pipe of the hydraulic system to physically cool the hydraulic system. 2. It is necessary to regularly maintain and maintain the machinery and equipment, strictly abide by the relevant procedures for operation and maintenance, and ensure that all components are operating normally without serious wear and tear. 3. Generally, after more than 1,000 hours of cumulative work, the hydraulic oil needs to be replaced.
Technical process of hydraulic oil radiator [06-08 09:40]
The hydraulic oil radiator is made of aluminum and vacuum brazed. A layer of sandwich is formed between two adjacent partitions by using fins, deflectors and seals, that is, a heat exchange unit body is formed, and each unit body is stacked differently and appropriately arranged in order, and brazed into The whole becomes a plate bundle, which is then equipped with a head, a takeover, a bracket and the like.
