Vibrating motor for concrete vibrating table

Types of vibrating motors for concrete vibrating tables

The purpose of the vibrating motor for concrete vibrating table is to create vibration in the working surface, which helps to remove air spaces and bubbles in concrete products and brings the mixture to the top for a better finished product. There are many different kinds of vibrating motors available for concrete tables and the same principles apply to any surface that requires compaction such as soil, sand or aggregate.

In general, the types of vibrating motors for concrete tables can be categorized into two main types: electrical and gas or petrol power.

• Electric vibrating motors: Electricity is the main power source for vibrating motors. It requires direct electricity or a battery to do the work. An electric power supply is a constant and does not require refueling like gas or petrol. An electric power supply creates a strong vibration. Depending on the voltage, different frequencies and strengths of vibrations can be controlled exactly to give the desired result. The advantage of using electricity is the bigger work and the ability to control the power better than other types.
• Gas or petrol-powered motors: Gas-powered vibrating motors run on different kinds of fuel. Each type of fuel needs a separate storage tank that provides the energy to make the motor run. Compared to electricity, gas motors are smaller because the fuel is stored in tanks. The gas motor does not need to be connected by wires, making it easy to move from one place to another, but it gives lesser vibrations. The type of fuel it uses will determine how much power and fuel it has to provide. Gas motors are used more for smaller work due to it being limited in power, and the fuel is more easily used outdoors.

Maintenance

• Routine check: Establish a daily routine check. Inspect the toolbox for any missing or damaged items. Look over the vibrating table for any signs of wear and tear or damage. Each vibrating motor has a manual that outlines the specific requirements for its maintenance. Ensure that the manufacturers’ manual on the servicing schedule is strictly followed.
• Lubricate parts: Regularly lubricate vibrating table motor components as outlined in the manual. Make sure to use the right type of oil in the right quantity. Parts that are regularly lubricated include chains and moving parts. Lubrication prevents excess wear and tear from friction.
• Pump oil: Ensure that the oil in the motor pump is always at the required level. Check the pump’s oil levels at least once a month. Add oil if the level is low to keep the vibrating motor pumps running smoothly and to avoid breakdowns. If there are any pump oil leaks, address the issue immediately.

By following the effective ways to maintain a concrete vibrating motor, its lifespan will be increased. The daily checks will ensure the equipment is functioning well. Repairs can be done early to prevent motor breakdown and to avoid interruptions in production.

Scenarios of vibrating motors for concrete vibrating tables

Some common usage scenarios of the concrete vibrating motor are as follows:

• Concrete consolidation

  The main application of concrete vibrating motors is to consolidate the newly poured concrete. Vibrating the wet-poured concrete with these motors helps remove the air gaps and form a stable and solid theorethical base. This process is essential for the production of high-quality concrete.

• Manufacturing high-quality concrete products

  The precise control over air removal from the wetted concrete is essential for producing concrete products like blocks, pavers, and slabs with consistent quality and uniformity. The durability, strength, and surface finishing of the concrete products can be improved with the help of these motors.

• Casting and mold filling

  Vibrating motors for concrete tables can be used during the casting process or filling molds. The vibration created by the motors helps settle the concrete evenly in the shape of the mold. It also helps the concrete take the full shape of the required mold. Using a motor driver concrete solidifies the process and enhances the overall quality of the cast or the molded product.

• Fabrication of precast concrete elements

  In the case of the production of precast concrete elements like beams, columns, and panels, motors serve as an essential part of the fabrication process. The motors promote uniformity in the consolidation of precast elements and reduce the development of air pockets.

• Dejaunction and consolidation of other materials

  Apart from the consolidation of concrete, the powers of these vibrating motors can also be used for the removal of air pockets from other materials. Examples of such materials include gypsum, asphalt, and aggregates.

How to Choose a vibrating motor for concrete vibrating table

There are some tips to help buyers of concrete table vibrating motors to make the right choice.

• Load Capacity: Knowing the amount of weight the vibrating motor can handle is crucial. The load capacity should match the weight of the concrete mix, the table, and any extra equipment that will be on the vibrating table. Buying a motor with a fitting load capacity will make sure it works fine and stop early wear-out.
• Frequency and Amplitude: Vibrating motors come with different frequencies and amplitudes. These two features control how much vibration the concrete gets. For compacting concrete perfectly and eliminating air pockets, buyers should choose a motor that offers the right balance between frequency and amplitude.
• Power Source: Some vibrating motors run on electricity, while others use air pressure. The type of power used determines how the vibration gets delivered to the motor. Choose a motor that allows for easy and good power delivery.
• Operating Environment: The place a vibrating motor is used matters a lot. If the motor will be used outside under harsh weather conditions, then a vibration motor with weather-proof features is necessary. Such features include weather-proof and dust-proof enclosures.
• Noise Level: Vibration frequency causes the level of noise a motor produces, so buyers should choose a motor that matches their noise level requirements. This may include selecting a motor with noise-reducing features like sound-proof encasements or selecting the motor with a particular frequency that reduces the noise level.
• Size and weight: The size and weight of a concrete vibrating motor matter when it comes to installation and use. Buyers should select a motor that is easy to install and can be used easily in the environment it is needed.
• Mounting options: The vibration of a motor affects how compact and uniform the concrete gets. Whether it is a rigid mounting or a suspended mounting, buyers should ensure they choose a motor with a suitable mounting option for the kind of application in use.
