In our review we have already encountered products from this plant, but we cannot ignore the platform-type model Krasny Mayak IV-98E. Such equipment is attached to the formwork or intermediate structure, the main thing is that the vibrator axis is located horizontally. Despite its purpose, it is a fairly compact design in a durable steel case that provides protection for the engine, shaft, unbalances and other components. In addition to being used for compacting concrete mixtures with high-density reinforcement, IV-98E can be used in the manufacture of vibrating tables, vibrating plates and other equipment.

Rating of the best deep-seated vibrators

Now let’s look at the best deep-seated vibrators, which received the most positive customer reviews and were liked by experts for their characteristics.

Operating principle of a deep vibrator

A concrete solution, in its essence and its purpose, is a composition, a homogeneous binding mass of a water-based mixture of sand, crushed stone, cement, consisting of lumps and particles of various sizes. To ensure high quality concrete, it is necessary that its constituent components are tightly connected to each other, and there are no air bubbles or cavities between them, thereby increasing characteristics such as strength and durability.

To produce such high-quality concrete mortar, construction equipment such as an internal vibrator is used. The device affects the slurry of concrete by oscillating waves during vibration, which promotes the settling of high-density particles and the release of air bubbles. The result is a homogeneous mass of concrete without air pockets or other defects inside the solution. The use of deep vibrators helps to increase the load-bearing properties of large-scale concrete structures. The unit is intended only for use with thick layer concrete, ideal for pouring a monolithic foundation or wall formwork. The downhole equipment is equipped with a long or short soft hose, which is used to ensure that the surface of the concrete is level during the pouring of walls or foundations, respectively.

Let's take a closer look at what happens during equipment operation. Operation of deep-hole equipment performs the following main functions:

• Compaction of the solution

The reliability of concrete lies in the uniform distribution of loads throughout the entire volume of the mixture. The properties of vibration help the filler to fill the volume of the void being filled with the same density.

• Air outlet

When a homogeneous mass of concrete vibrates in the solution, pressure arises, which undoubtedly helps air bubbles break through the thickness of the concrete to the outside. The fewer empty cavities in concrete, the stronger and more reliable it is.

• Cavity fillings

Types of vibrators for concrete and criteria for their selection

First, let's look at the general characteristics that are relevant when choosing both deep and surface devices.

What all vibrators for concrete compaction have in common

Now let's try to understand the features of choosing deep-type devices. They are the most popular solution for pouring reinforced concrete structures.

Data for selecting submersible models

* keep in mind that the tip gets very hot during operation - this is normal, just be careful.

Well, if you decide to purchase a surface vibration compactor, then when choosing you need to take into account the following features, which mostly relate to the equipment.

Data for selecting external type equipment

It is worth noting that the effective range of both equipment options usually does not exceed 0.5 m. This suggests that the step of rearranging deep vibrators should not exceed this value.

Accessories and spare parts

For the most part, this question concerns immersion-type equipment, in which flexible shafts and tips are consumables. Most often, the manufacturer offers a set of shaft and club for full compatibility of components. The cost of such products depends on their parameters, for example, the diameter of the tip and the length of the flexible shaft.

How to choose a deep vibrator

Deep concrete compaction devices have several key characteristics that need to be taken into account when choosing:

1. Power.
   The higher the power, the longer the equipment can work without interruption and the better the performance. Deep models with an indicator of up to 1 kW are used in everyday life to create a strip or square solid foundation for the construction of one-story houses, cottages, garages and utility rooms. Vibrators with a power of 1-2.5 kW are semi-professional and are the most common. Such equipment is suitable for the construction of buildings with several floors. 3-20 kW are of the professional type and are used for compacting concrete in columns and supports during high-rise construction.
2. Club diameter.
   The diameter of the tip, which is immersed in concrete, can be 25-100, which determines the range of action. But the larger the knob, the more difficult it is to insert it between the reinforcement bars, which is important to consider when choosing.
3. Shaft length
   . The size can be 1-15 m. When compacting the screed, the vibrating tip must reach the very bottom, so for high foundations 1-1.5 m long shafts of 3 m are needed. The length of the shaft also affects the maneuverability of the operator on the construction site. The shorter the flexible tube, the more often you will have to rearrange the base or constantly carry it in your hands.
4. Oscillation frequency
   . Values ​​of 3-9 thousand vibrations/min are useful for strip foundations and small armored belts during domestic construction. For professional activities, devices with 10-24 thousand vibrations per minute are chosen.
5. Radius of action.
   The value is always indicated in the product passport and affects how often the mace will have to be recessed. The indicator is 30-50 cm, so the vibrating tip is immersed every 60-100 cm, respectively.
6. Weight of the block and vibrating tip
   . The weight of the mace with drive and motor varies from 2 to 12 kg. The lighter the weight, the easier it is for the operator to raise and lower the shaft. But with high foundations of 70-150 cm, it is more convenient to immerse the heavy knob to the bottom.

Differences between deep vibrators by power drive

The deep vibrator may include the following types of drives:

• Diesel;
• Petrol;
• Electric.

Diesel or gasoline drives are equipped with engines based on the principle of internal combustion of the corresponding fuel. The huge advantages of such drives are their autonomy and the ability to operate in any environmental conditions. The disadvantage is the regular waste of money on diesel or gasoline fuel. Due to the release of toxic gases resulting from the combustion of flammable fuel, deep-well vibrators with diesel or gasoline drives are not recommended for use in closed and unventilated areas to eliminate the possibility of poisoning of working personnel. If we compare diesel and gasoline equipment, then a vibrator operating on the basis of diesel fuel is much more powerful and economical, but more expensive in price.

The electric drive that powers the deep vibrator is very popular and widespread due to its simplicity and operation. Electric motors from a general network of 220 V operate directly from an outlet, and motors with a voltage of 380 V operate through a transformer that reduces the voltage to 48 V. The disadvantage of such a deep vibrator is the inability to operate the equipment without connecting to an electrical network. Connecting a vibrator to an electricity generator will help solve this problem.
