The difference between high-speed motor hood and ordinary motor hood

Classify：Company news Release time：23,Oct,2023

1, the expansion of the ordinary motor hood is to rely on the friction between the section and the section to push each other, because the friction between the sections is not the same, resulting in the expansion of the section movement is not synchronized, not parallel, some sections even stagnant phenomenon. Impact vibration, noise, shorten the service life and affect the overall performance of the machine tool, in the machine tool moving at high speed, its shortcomings are particularly prominent. The wind hood of the high-speed synchronous telescopic guide motor is equipped with a synchronous mechanism, so that each piece moves synchronously when it is telescoped, avoiding impact and vibration, reducing noise, extending service life, truly achieving smooth operation, flexible expansion, and ensuring the overall performance of the machine tool.

2, the special structure of the oil scraping plate and high elasticity, high wear resistance, high temperature resistance, oil resistance of the special scraping strip makes the sealing, protection performance more reliable, longer service life; The special structure of the oil scraper and the oil scraper makes the cleaning and replacement of the oil scraper very convenient, the maintenance is more simple and convenient, and the overall reliability of the motor wind hood is higher.

3. The application range of the motor hood is more extensive, in addition to being especially suitable for the machine tools with high moving speed, high acceleration and deceleration, it is also especially suitable for the machine tools with large stroke and large protection width. For machine tools with large stroke and large protection width, if the ordinary motor hood is still used, the shortcomings of the ordinary motor hood are more prominent because of the number of sections and the large width of the hood and the large weight of the hood. The simultaneous telescopic guide motor hood with double simultaneous mechanism can make up for the shortcomings of the ordinary motor hood, so that the parallel performance of the moving is better, and the overall performance of the machine tool can be guaranteed.

How to use centrifugal fan is correct

Even if the user can choose a good one when choosing a centrifugal fan, if the user does not strictly follow the instructions in use, it will reduce the use effect of the fan, and even shorten the service life of the centrifugal fan, which is also a great loss for the user. The correct use of the centrifugal fan can not only ensure its use effect, but also reduce the service life of the centrifugal fan. It can also extend the service life of the fan to a large extent, so many users want to know how to use is correct, in order to reduce the damage to the fan? Today we are going to introduce some tips for using centrifugal fans. I believe that as long as the user has mastered these can certainly improve the efficiency of the fan to a certain extent.

The use of centrifugal fans begins with its start-up. There are many reasons why a startup fails or takes a very long time to start. If the motor does not move, check the setting value of the mechanism; If the motor rated power is too low, replace the motor; If the starting program is not correct, adjust the starting equipment; If the power consumption is too large when starting, verify whether the gas flow control mechanism is in the off position when starting; If the rotor is stuck, move the fan by hand to check and investigate the cause of the stuck (friction, obstructions, etc.); If the voltage at the motor connection is too low, check the power line voltage - if the loss is too large, increase the power line.

Many times the user will find that the impeller is always in the white consumption of energy. Gas circulates through a leak between the front cover and the collector. It is necessary to maintain a certain gap between the front cover of the centrifugal fan and the collector and between the casing and the rotating shaft. To ensure the reliability of fan rotation. This can alleviate this phenomenon to a great extent.

The common problem in the use of centrifugal fans is the vibration of the fan, and it is not a simple matter to fundamentally solve this problem, but if the speed of the fan is reduced, it is a very good way, and the effect of this method is also significant. However, users also need to determine what method to use according to the specific situation of the fan used to be more reasonable.

How important the motor hood is for motor protection

There are many components of the motor, such as the ratio coil, rotor, wire core, wind hood, oil seal, etc., a high-quality motor must have these high-quality components. Therefore, these motor components are also very important and should be paid attention to. Today, Wuxi Vertical and Vertical Electromechanical small make up to share with you is one of the components of the motor "motor hood", let's see how important the wind hood is for the motor!

Compared with other parts, the motor hood is more often understood as the important performance of the motor to block the fan and ensure the safety of mechanical operation, so many motor manufacturers do subtraction on the design of the hood, which seems to be in the form of parts standardization, inadvertently ignoring the motor performance level, especially the impact on the motor temperature rise, efficiency and noise performance.

From the specification of the motor manufacturer's products, we can find that the same series, the same center height, different pole number, different power of the motor, the shape of the hood, the height, the number of end holes and position of the hood, there are some differences, the differentiation and fine design of the motor wind path will be reflected in the hood, the final competition of product performance may not be entirely the use of copper and iron. It may also be reflected in these small, not every manufacturer pays attention to the link.

Some knowledge about the motor hood:

If the motor is run indoors, it is relatively simple to make; But if the motor is running outdoors, that is, we say outdoor motor, then we have to consider its special requirements such as moisture, dust and rain.

For the vertical installation of protective outdoor motor, on the one hand to ensure the ventilation and heat dissipation of the motor, that is, to install fans and hoods, but the hood will have ventilation holes, in order to prevent rain into the motor, we will add a rain cap above the hood, so as to prevent the direct intrusion of rain.

This rain protection is like we use an umbrella on a rainy day. In more cases, the rain cap and the wind hood are welded together by welding, which will not only interfere with the ventilation and heat dissipation of the motor, but also play the necessary protective role, and lose the overall beauty of the motor.

We want to emphasize here that the diameter, shape and stability of the rain cap, as well as the relative distance from the top of the wind hood are very critical, both in the pursuit of beauty, but also pay attention to practical results.

The working principle and use of the motor hood

The motor hood is usually used to improve the efficiency of the fan. In short, the fan blowing outside should eliminate other areas where air may leak, allowing the fan's wind to pass through the radiator as much as possible. For fans that suck in air, this is so that as much air as possible comes from the radiator and not from somewhere else. Therefore, the higher the fan efficiency, the smaller the gap between the fan blade and the fan cover, the higher the efficiency.

Many vertical and horizontal motor users may not notice the motor accessories, such as the motor hood, but in fact, the safety accidents caused by the motor hood damage every year are not uncommon, and today we will talk about the role of the motor hood.

The vertical and horizontal motor drives the rotation of the fan blades, the rotation of the fan blades makes the air flow form the air flow, and guides it to the hood to form a stable direction, and the wind hood also has a protective function.

The working principle and use of the motor hood.

1. When the motor is running indoors, the function of the wind hood is relatively simple, protecting the fan from damage and avoiding fan injury.

2. The windshield plays a role in protecting the motor in special working environments. For example, to prevent dust and liquids, etc. Please do not enter the motor.

3. Confirm air access. Many motors are now in air-cooled mode, and the function of the wind hood is to direct the wind from the main fan along the specified route, eliminating heat as much as possible.

Although the motor hood looks insignificant, it has not been seriously accepted as a cover for loading things, in fact, it plays a very important role in the safety of the production of the factory, especially in the safety of the vertical motor used outdoors.
