Carrying out some work, mainly those relating to concrete, is sometimes either impossible or takes too much time if done manually. Therefore, in some situations, it is necessary to use such a tool as a deep-frequency vibrator.
General description of the device
This tool has become widespread among those people whose work quite often intersects with the construction of monolithic structures. The amount of concrete being kneaded in such cases is simply enormous, and therefore it is almost impossible to prepare it manually, and then pour and level it in place, since the time and effort will be huge. It was for such cases that a deep high-frequency vibrator was invented.
In simple and understandable language, the primary task for which this device is used is the removal of oxygen from the concrete mixture. Also, using this device, you can make the existing concrete mix better and more compacted.
The purpose of using the tool
The purpose of this device is to improve the technical characteristics of concrete mortar. However, like any other technical device, the deep-frequency vibrator has several limitations. Operation is subject to the following conditions:
- the surface on which the work is carried out should not be higher than 1000 m from sea level;
- temperature range of the unit from +40 to -40 degrees Celsius;
- if the ambient temperature is +20 degrees Celsius or higher, then use is allowed only if such an indicator will be stored for no more than 12 hours a day.
The use of a deep-frequency vibrator is also allowed in a closed room, but only if there is natural ventilation. Another important condition is the preservation of the natural climatic conditions inside the building. With artificially created parameters, such as humidity and temperature, the result of the work will be too different from the natural.
Unit Features
The main feature of this device is that vibration is created directly inside the concrete mortar. Most often, it is precisely because of this property that these devices are fairly well established in everyday life, and the construction of any large facility is not without them. If we talk about the quality of the model, then this parameter is determined by such ability as determining the zone of work, which should be ten times the size of the vibrator head of the device.
It is also worth noting another important feature, which is that when the device is used at low speeds, when immersed in a concrete mixture, the speed of rotation of the mace will decrease even more. For this reason, the working area of ββthe high-frequency deep vibrator will drop dramatically. This is pretty bad, because it will greatly increase the time required to complete the work.
Device operation
Despite the fact that the use of this device is quite simple and straightforward, there are still several recommendations that should be followed when operating the unit. Suppose one of the recommendations from professionals is that the choice of placement of the device for inclusion is very important. The best place is the place in the tank where the vibration is located in the center of the intersection. Turning on the device at this point will greatly increase the speed of work. In addition, the quality of the final concrete mix will also improve. Thanks to this, there will be confidence that there is no oxygen between the formwork and the mixture at all, which means the resistance of the entire structure has become even higher.
If a person is faced with the task of mixing the newly applied concrete layer, then the high-frequency deep vibrator must be immersed in the lowest layer and not less than 12 cm.
This will help much stronger and better bond the layers of the mixture with each other, completely remove the oxygen that can accumulate in the interlayers, and the whole structure will be more reliably protected from such a defect as the occurrence of cracks.
Device design
One of the main advantages of this unit lies in a very simple structure. For example, a simple electric motor with two or three phases is usually used as a drive for this device. A rotor is also included with this item. It is important to note here that the model of this part must necessarily be short-circuited.
It is he who gives the possibility of mechanical movement for the entire structure. If we talk about the shaft of the vibrator, then here the length and thickness can be very different. Which deep-frequency vibrator to choose, everyone must decide for himself. It is necessary to be based on what kind of work this device is bought for.
It is important to add that depending on the type and size of the formwork, it will be necessary to use different tips. Most often, several types of vibrator clubs are already included with the device, the difference between which lies in their diameter.
Vibrator IRFU 45
The manufacturer of this model was the company WASKER NEUSON SE. The most common type is a deep-frequency vibrator IRFU 45/230 with a converter. The operating voltage for this model is 220 V. The power required to operate the device is 700 watts. With these indicators, the maximum number of revolutions reaches 12,000 per minute. The shaft length can reach 5 m. In this case, the length of the vibratory tip or mace is 382 mm, and its diameter is 45 mm. With these indicators, the weight of the part is 14.6 kg.
The manufacturer focuses on the safety of use and on the high performance of its products. On such models, a protection system from the same company is installed, which is designed to ensure complete safety of both the machine and the operator throughout the entire period of work, starting from the moment it is turned on. In addition, a converter built into this model allows you to connect the device to any outlet with 1 phase and a voltage of 220 V.
Vibrator deep high-frequency V-MAX 50
The production of this model involved in Italy. The main indicators of this vibrator are high quality that meets all European standards, as well as an affordable price. Today, it is this model that is considered one of the cheapest European suppliers on the Russian market. The assortment is quite wide. Four standard sizes are available for the vibrator head - 38, 50, 60 and 70 mm. In standard production, the hose length of the device is 5 meters. However, if the customer wishes, it is possible to increase the length to 20 meters. Included with the device is also a converter from the same manufacturer. However, it is worth noting that you can connect the unit to almost any other converter from a well-known company.
Some companies are engaged in the production and sale of deep high-frequency vibrators in Minsk; you can also rent a unit if a small amount of work is expected.
