Maintaining and Repairing the Vibrating Motor

Do you know the motor vibrates? It is a kind of electric motor which obtains the vibrating force through the effect of centrifugal force. This centrifugal force is generated by the eccentric shaft and block with fast rotating speed. These motors are widely used in many industrial sectors, such as hydropower construction, thermal power generation, metallurgy and light industry.

Because this vibrating motor is quite applicable, how to maintain and repair it is the concern of many people. As far as we know, most of the motors are installed in dirty working environment and while this motor has no fan to dissipate heat. So based on these factors, some specific aspects of the vibrating motor must be maintained.

What specific aspects of the vibrating motor should be maintained? Priority is given to the scope of inspection: (a) check the cleanliness of the motor surface; (b) remove dust immediately. Or else, it will have bad influence on heat dissipation; (c) check whether the fixed bolt of the tail is flexible or not; (d) tighten the torque by force with a wrench when the moment becomes flexible; (e) check whether the vibration is abnormal or not. Next, this article will introduce the processing method. First, when the vibration is abnormal, people should stop the electric motor. Second, people check whether the seal of the protective cover is tight. Otherwise, people should stop the operation. Third, the public must also pay attention to whether the motor cable is worn or not. If the wear is serious, the motor must be stopped. Fourth, remember to add oil under the grease gun every two months.

In addition to the things mentioned above, several other things must also be considered by the workers. For example, the bearings used in these electric motors must be heavy bearings because they can withstand thrust loads. Wherever installed, bearing life is not affected by thrust loads. What’s more, it is better to choose an elastic cable as the main cable, because ordinary cables are easy to wear or break.

In short, the vibrating motor has a destructive effect on the entire equipment. Therefore, if people do not use it accurately, not only will the service life of the motor be shortened, but also the related equipment will be destroyed. In order to take full advantage of the vibrating motor, it is recommended that people inspect and maintain it frequently.

Tips for Using a Liquid Level Sensor

The liquid level sensor is used to detect the level of a liquid or the interface between a liquid such as oil and water or a liquid and a solid. These devices can be described as sensors or transducers, or an integrated system with instrumentation and control capabilities. The point liquid level sensor often triggers an alarm or shuts down the system based on a certain limit. This time, this article will provide some great tips that will guide you in using the liquid level sensor. Well, just look at the tips below.

The first thing you should do is place the tool on a plastic case. You can use this special device if the container is opaque and cannot be opened, or if the liquid may be hazardous if exposed to open air.

The second thing you need to do is move the sensor under the top of the tool. You should pay attention to the sensor for indications that detect liquid on the other side of the container. This is usually indicated by a flashing light or an audible beep.

The third thing you should do is slowly move the sensor up the sides of the case. After that, you need to monitor for indications that the sensor is now above the liquid level in the container. Then, you’ll need to move it back under the container until it ignites again to determine where the top of the liquid is.

Anyway, by looking at the information above, you can now easily start using this sensor for your projects. By using this tool properly, you will get the best results in doing your job.

Uses of Load Cells

Load cells are available in a variety of shapes, sizes and capacities and are now the industry standard for all types of weighing. This can be a bit of a minefield trying to find the correct load cell for your application. I have listed some of the most commonly found today and their uses.

Single Point – Single point is probably the cheapest and most popular type on the market today. Because of their price and reliability, they can be found in most types of retail scales, weighing scales, medical scales, parcel scales, and postal scales. This type of load cell can also be used in platform scales and industrial weighing systems to provide accurate readings regardless of the position of the load on the platform, reducing manufacturing costs.

Tube type – The tube type has been around for a long time and is likely to become the industry standard for most high capacity compression applications. Tube type load cells are used for single and multi weighing applications. This type of cell has buttons on the top and bottom sides and can only be used in compression. Tube-type load cells are used in tank scales, ship weighing applications, axle scales, truck scales, vehicle scales and weighbridges. Tube type load cells offer accurate weighing in harsh environments.

Double Ended Shear Beams – For medium to high capacity applications, double ended shear beams offer a number of advantages over other designs. This type has the ability to sway on the stand to accommodate misalignments in the mounting surface while still being maintained, it also allows limited movement to allow thermal expansion and contraction as well as lifting protection. This cell type is also available as a weighing module kit.

Single End Shear Beams – Single ended shear beams are commonly found in all types of floor, platform and shipping scales today and provide the ideal solution for most medium capacity weighing applications. The single end shear cell has the ability to withstand full capacity side loads without any problems which makes it particularly suitable for weighing systems with mixers, blenders and agitators. This type is very durable but can be expensive and impractical to install above 10,000 kg. This cell type is also available as a weighing module.

Tension Links – Tension links are suitable for applications such as winching, hanging scales, crane scales and lifting systems. This type of load cell offers superior accuracy in high capacity weighing. This type of cell has openings at both ends for easy connection to shackles, wire ropes, D links, or other rigging. Tension link load cells provide a robust design for resistance to side loading.

Torque Rings – Torque rings are a relatively new design concept and provide an excellent low profile solution for a wide range of weighing applications. Unlike standard compression load cells, which can easily suffer from off-axis loading problems, the torsion ring is loaded via an annular ring located in the middle. By using a central float pin to transmit the load to this ring, optimal load recognition is ensured and off-axis loads of up to three or four degrees can be tolerated without loss of performance. Exclusive mounting modules, which offer great versatility, are now available for process weighing and platform weighing applications.

Weighing Modules – Weighing modules generally consist of load cells with mounting kits. Many types now come supplied as modules but generally single or double shear beam and tube types are the industry standard. Load cell weighing modules are used in tank scales, silo weighing, ship weighing applications, axle scales, truck scales, vehicle scales and weighbridges.

Wireless – All of the above has one major drawback; they are connected to the device via a cable. One of the main problems with weighbridges or floor scales is the possibility of damaged cables. Using the latest technology, wireless, load cells are now available and could one day become the industry standard. All of the above load cells are now available in wireless format, although this technology is very expensive.

Type S – Type S gets their name from their shape, being the letter ‘S’. S type load cells can provide digital output when used in either tension or compression and provide superior side load rejection. This type of cell has two female threaded mounting points, the top and bottom are where eye bolts or threaded rod ends can be attached. This type is used in crane scales, hanging scales, hoist scales, and most tension applications.
