How many types of concrete vibrators are there? 5

Concrete vibrator is driven by a motor and then driven by a flexible shaft, which increases speed through the planetary mechanism to obtain high-frequency vibration. There are many types of concrete vibrators. According to the way of transmitting vibration, it can be divided into three types: internal vibrator, external vibrator and surface vibrator; According to the power of the vibrator, it is divided into three types: electric, internal combustion and pneumatic, and the electric type is widely used; According to the vibration frequency of the vibrator, it is divided into three types: low-frequency, medium-frequency and high-frequency; According to the principle of vibration generated by the vibrator, it is divided into two types: eccentric type and planetary type.

There are two commonly used concrete vibrators: attached (flat plate) concrete vibrators and plug-in concrete vibrators.

According to the power supply mode: gasoline engine, diesel engine, three-phase electricity, single-phase electricity.

By power:

Concrete vibrating rod is divided into diameter, etc., the commonly used diameter 50 action spacing is 300mm, how long is the approximate vibration at a time is not specified, generally see the concrete surface does not appear bubbles on the surface of the concrete to indicate that the concrete below reaches the degree of compactness, if the steel bar spacing is too small, it is necessary to use the concrete vibrating rod of 30mm.

There are the following types of vibration motors: YZS series vibration motor YZU series vibration motor JZO series vibration motor YZO series vibration motor TZD series vibration motor TZDC series vibration motor.

ZF, ZW series attached concrete vibrator.

It depends on what you want, look at what you asked.

What is the difference between the vibrating plate and the vibrator for beating concrete: the difference: 1. The plug-in vibrator is a vibrator in the shape of a rod.

When it is used, the head of the vibrating rod is inserted into the concrete, and then the vibration inside is relied on to achieve the vibration of the concrete. Specifically, there are the following three requirements. ①：

We need to pay attention to the height of each concrete pour. The pouring height is generally a multiple of the length of the acting part of the general vibrator. For example, our floor slabs can be poured in one go, because the thickness of the floor slabs itself is about 13 cm to 15 cm.

When using a plug-in vibrator to vibrate concrete, it should be inserted quickly and pulled slowly. The insertion points should be evenly arranged.

Moreover, it is carried out in the order of point-by-point movement according to the point, and it is required not to be omitted, so as to achieve uniform vibration. : The spacing between the vibrators should not be greater than the radius of the vibrating garlic.

Generally speaking, it is 30 to 40 cm. When vibrating the previous layer, the next layer should be inserted 5 to 10 cm so that the two poured concrete can be combined. In the process of vibrating, the vibrating rod shall not touch the embedded parts or templates.

2. The plate vibrator refers to the lower part of it is a flat plate, which is realized by the vibration of the upper part of the machine. This machine is installed on the upper part of the slab, and the vibration of the machine drives the vibration of the slab to achieve the vibration of the lower concrete. For the use of the tablet vibrator, pay attention to the following problems.

The distance of each movement of the plate vibrator should be able to ensure that the part that has been vibrated and compacted covered by the plate vibrator. In other words, there should be no vibration leakage in the middle.

The direction of the vibrating sequence should be consistent with the direction of the concrete flow as much as possible. In this way, the spring of the people can effectively make the concrete that has been vibrated no longer go into the free water and bubbles.

The standard for passing vibration is to slightly slurry and water on the surface of the concrete. After these two phenomena occur in Suiqing, we can judge that we are qualified to vibrate.

In addition, it is important to note that vibration leakage and vibration should not be excessive.

Hello dear <>

<>First of all, the concrete floor vibrator is a device used for the vibrating surface of the concrete skin, which can make the concrete surface smoother and more resilient, and at the same time, it can also improve the compactness and strength of the concrete. When choosing a concrete floor vibrator, the following factors need to be considered:1

Power: The greater the power of the concrete floor vibrator, the better the vibration effect. Generally speaking, vibrators with a power of more than kilowatts work better.

2.Amplitude: The greater the amplitude of the vibrator, the better the vibration effect.

In general, vibrators with an amplitude of more than 1 mm work better. 3.Frequency:

The higher the frequency of the vibrator, the better the vibration effect. In general, vibrators with frequencies above 100 Hz work better. 4.

Weight: The greater the weight of the vibrator, the better the vibration effect. Generally speaking, vibrators weighing more than 10 kg work better.

Generally speaking, at least you need to choose a vibrator with a power of more than 1 kilowatt, an amplitude of more than 1 mm, a frequency of more than 100 hertz, and a weight of more than 10 kg to achieve a better vibration effect.

The difference between three-phase concrete vibrator and two-phase concrete vibrator, is there a difference between them?

The three concrete vibrators are important machinery in the construction of modern concrete engineering. Where concrete components are poured, those who can insert vibrators can use them. Such as:

Pouring concrete columns, walls, main beams, secondary beams and prefabricated components, etc. It is especially suitable for pouring light and small parts and thin-walled components, and can be adapted to vibrating plastic, semi-dry hard, dry hard concrete and dusty soil. It is more efficient to vibrate concrete!

The two phase vibrator is weaker than the three vibrations, you think about it, the two electric voltages are 220, the three voltages are 380V, under the same power, the vibration frequency of the three electric vibrators is greater than the two terms, this is buried and used two electricity to grind the surface is a reason, the surface of the two electric grinding is slightly slower than the speed of the three electric brother buried machine. However, in some places, there are no three power supplies, and it is also practical to choose two electric vibrating rods with higher power.

1. Electric plug-in vibrator.

1) Leakage protection device should be installed on the motor power supply of the plug-in vibrator, and the grounding or zero connection should be safe and reliable. (2) The operator should be educated on electricity, and should wear insulated rubber shoes and insulating gloves during operation.

3) The cable should meet the length required for operation, and the cable shall not be stacked or squeezed by the vehicle, and it is strictly forbidden to drag or hang the vibrator with the cable.

4) Before use, check all parts and confirm that the connection is firm and the rotation direction is correct.

5) The vibrator shall not be tested on the initial concrete, floor oak, scaffolding and dry and hard ground. When the maintenance operation is interrupted, the power supply should be disconnected.

6), during the operation, the bending radius of the vibrating rod hose shall not be less than 500mm, and not more than two bends, the vibrating rod should be vertically sunk into the concrete during operation, and shall not be inserted hard, obliquely pushed or let the steel bar clamp the rod head, and shall not be fully inserted into the concrete, the insertion depth shall not exceed the length of the rod 3 4, and the steel bar, core pipe and embedded parts should not be touched.

7) The vibrating rod hose shall not be broken, and the hose should be repaired or replaced in time when the length of the hose is used for too long. (8) When the operation stops and the vibrating beam rubber vertical is moved, the motor should be turned off first, and then the power supply should be cut off. The motor must not be dragged with a hose.

First, the choice of power form.

Electric vibrators are generally used in building construction, and when the construction site only has a single-phase power supply, a vibrator with a series excitation motor should be selected; When there is a three-phase power supply, a variety of electric vibrators can be used. In a working environment with gas, a pneumatic vibrator must be selected to ensure safety. If you are working on a temporary project far away from the town and without a power supply, you can choose an internal combustion vibrator.

Second, the reasonable choice of structural form.

Plug-in vibrators can be used for the compacting of columns, beams, walls, and slabs with large thickness of large-area concrete foundations, as well as prefabricated components; Attached vibrators can be used in structures with dense steel bars or thin concrete, as well as in places where plug-in vibrators are not suitable for use; Flat plate vibrators are usually used for large and flat surface areas, such as the ground, roof, road pavement, etc. The hollow slabs, slabs and beams and columns with small thickness produced by the reinforced concrete prefabricated component factory can be quickly and effectively compacted by using a vibrating table.

Third, the selection of plug-in vibrator.

The vibration frequency of the vibrator is an important factor affecting the tamping effect, and only the vibration frequency of the vibrator is the same or close to the natural frequency of concrete particles in order to achieve the best tamping effect. Since the resonance frequency of the particles depends on the size of the particles, the natural frequency of the large size is lower, and the natural frequency of the small size is higher, so for the concrete with large and smooth aggregate particles, the plug-in vibrator with low frequency and large amplitude should be selected. Dry hard concrete should be selected high-frequency vibrator, which can improve the compaction effect, increase liquefaction, expand the compaction range, and reduce the tamping time, but it is not suitable for concrete with a large fluidity, otherwise the concrete will produce segregation.

According to the composition of the concrete of the building construction, it is more appropriate to choose a high-frequency vibrator. The structure of the plug-in vibrator is mostly flexible shaft type, light and flexible, can be carried and used by a single person, can be adapted to the upper and lower floors or through the narrow place passage, etc., and the transfer is very convenient, which is very suitable for the use of grassroots building units.

1. The attached and flat plate vibrator bearings should not bear the axial force, and the motor shaft should be kept horizontal when in use. 2. When multiple attached vibrators are used on a template at the same time, the frequency of each vibrator should be consistent, and the vibrators on the opposite side should be staggered and installed. 3. Before operation, the attached vibrator should be inspected and vibrated test.

The vibration test must not be carried out on dry hard soil or hard objects. The vibrator installed on the silo of the mixing plant should be placed with a rubber pad. 4. During installation, the position of the mounting screw hole of the bottom plate of the attached vibrator should be correct, and the chassis should be prevented from being damaged by the twisting of the anchor bolt installation.

The anchor bolts should be tightened, and the degree of tightness of each bolt should be consistent. 5. When the vibrator is used, the cable shall not be stretched too tightly, let alone broken. During operation, the leakage of electrical equipment should be observed at any time, and the electrical equipment should be observed and confirmed to be qualified.

6. When the attached vibrator is installed on the concrete formwork, the vibration time should not exceed 1min each time, and the vibration can be stopped when the concrete is slurry flowing or horizontal in the mold, and it shall not vibrate again when the concrete is in the initial setting state. 7. The motor and plate of the flat plate with wild vibrator should be insured.
