Pneumatic pick hammer: technical characteristics and operating principle

A jackhammer is a tool without which no construction or dismantling works pass, especially where it is necessary to loosen or break solid rocks. The equipment can cope with concrete, asphalt and some mountain sedimentary rocks. Today, a pneumatic pick hammer is very popular for a variety of reasons, as will be discussed a little later. Let's see what technical characteristics such a tool possesses and how to choose it, in fact.

Some general information

At the very beginning I would like to note that the pneumatic jackhammer is considered a very effective and reliable tool. But if earlier such luxury was only available to miners who, with the help of bumpers, mined ore, today they are widely used in construction and road works. You can talk about a wide range of application tools. If necessary, you can break through a niche in the wall, loosen the hard rock, treat the asphalt and so on. In any case, replace with something better and more high-tech bumpers can not. Of course, if you compare the first jackhammers and those that are sold now, then it's heaven and earth. This applies to the weight, convenience of work, and technical characteristics, and even the design of the product.

On the main advantages of pneumatics

It should be noted that pneumatic bumpers are very popular. This suggests, at least, that they have significant advantages over obsolete options. For example, the absence of sparks during the execution of work is very important. The probability of ignition or explosion in this case is absent. Consequently, it is advisable to use such equipment in mines. It is impossible not to say about such a strong side as the wide possibilities of power adjustment. This allows you to perform work of varying complexity and purpose. This is facilitated by two modes of the tool. As for the main and most significant shortcoming that a pneumatic hammer has, is the presence of a compressor. The latter is needed to supply compressed air. This is noisy and bulky equipment, which is also volatile. All this significantly increases the price of pneumatic bumpers.

Briefly about the device

Absolutely all models work in the same way. Some units are equipped with additional mechanisms and functions, which, although complicate the design, but make the work performed more efficient, quick and safe. In our case, the device is completely based on compressed air. He goes to the piston, forcing him to move up and down. From the piston, the force is transferred to the working nozzle, which contacts the surface to be treated. Naturally, at the present time a huge number of working attachments are produced. Each of them is designed to work with material of different hardness. The pneumatic hammer has a damper, which is adjustable depending on the direction of pressure. This contributes to the fact that the piston moves in one direction, then the other. After you press the starting lever, the valve opens and the air from the compressor comes under pressure to the piston.

Pneumatic pneumatic hammer: technical characteristics

It is extremely important to take into account the technical characteristics when choosing a bump stopper. This tool is divided (depending on the impact energy) into several groups:

• Equipment with an energy of 30 J is well suited for work in cramped conditions or at height. This is facilitated by the light weight of the unit.
• A tool with an impact energy of 40 Joule is good for doing general work on a construction site.
• 50 Joules and above are suitable for too hard material. And it is necessary to understand that the harder it is to process the surface, the more the impact energy should be.

It is worth saying a few words about the fact that there is a large selection of baits. The standard version sets a peak, but if necessary it can be replaced with a chisel or a crowbar. It is extremely important that the pneumatic pneumatic pick hammer, whose technical characteristics we have already partially considered, had a small weight. Usually it ranges from 1.5 to 10 kg. Such equipment is convenient and easy to maintain for a long time.

Hammer pneumatic pneumatic: MOP-2 or MOS-3?

We have already sorted out a little with how this kind of equipment works, and now we will consider a few more interesting points. MOSF stands for "hammer pneumatic pneumatic hammer". It is worthwhile to draw your attention to the fact that the MOS-2 and MOS-3 differ only by their technical characteristics. The burglar of the third generation is more powerful and perfect, as it was released later by MOS-2. However, using it in some situations is impractical or just not necessary.

MOP-2 and MOS-3 operate at the same compressed air pressure of 0.3-0.5 MPa. But the impact energy in the bump of the third generation is more by 6 J and is 44 Joules. At the same time, the pneumatic hammer MOP-3 weighs the most by 400 grams, which is not at all essential. As for the appearance, the tools are practically identical, they have the same design and device, but the MOS-3 is more powerful and reliable.

Speed of work performed

If to understand more in detail, it is possible to distinguish two major technical characteristics. One of them is speed. Solid models from well-known manufacturers have better performance characteristics. For example, a MOS with an impact energy of 60 J can operate at a rate of 1000 beats per minute. This will be enough for almost all types of work. But you should pay attention to the fact that in this case, the operator will face an impressive weight of equipment. In the market you can find models at a speed of 3000 beats per minute, light weight and the same impact energy. The peculiarity of this solution is that the price will be higher, and the work performed is somewhat more complicated. In any case, it is better to give preference to something mean, then the speed will be optimal, and the weight is acceptable.

A little about the power of the equipment

The second characteristic is the power of the tool. If previously sold units that could only work at a fixed mark, then today it is better to buy bumpers that have a power regulator. The benefit of choosing such a model will not be difficult. Light bumpers can work at 8 Joules, and the most powerful aggregates are approximately 60 Joules. The lower mark will be sufficient to handle not very hard surfaces and sedimentary rocks. The upper threshold is used quite rarely. Also you should know that there are electric breakers. Such a tool must have at least 500 and not more than 2000 watts. The situation with the bottom and top marks is similar to the pneumatic equipment. From all of the above, we can conclude that it makes sense to pay attention not only to the speed, but also to the power of the unit. At the same time, the pneumatic hammer must be as simple as possible, which will make it more reliable.

About vibration damping and comfort of operation

It's easy to guess that a person who has worked for about 6-8 hours on a bump is very difficult. Vibration is the cause of many diseases, so they are always trying to maximally pay off. For this purpose, special gloves and clothing, as well as other personal protective equipment, are used. In the case of pneumatic equipment, you do not have to worry about the operator's well-being. This is due to the fact that engineers were able to design a design that helps absorb 70-75% of the vibrations. Unfortunately, it is impossible to completely eliminate such an undesirable effect. When buying a tool, pay attention to the fact that the pneumatic hammer (MO) has a noise silencer. Due to the fact that this technique is very cumbersome and noisy, in particular, the inconvenience creates a compressor. With noise silencer and ear plugs, you can achieve a good result and work in more or less comfortable conditions.

Instead of concluding

Another small, but at the same time rather important detail is that you need to pay attention to ergonomics and design. For example, the ribbed handle makes it easier to hold the tool. All levers and buttons should be positioned so that they can be reached without stopping the process of chiselling. In addition, pay attention to the quality of assembly. The casing must be tight and rigid - this will guarantee a long working tool. If you still need repair pneumatic hammers, it is better to contact the service center, and not try to do something on your own. Otherwise you can only make it worse.

That's all that can be told about the principle of the pneumatic hammer. Technical characteristics we have reviewed, so you know what to look for first thing when buying. Purchase only tested units, preferably from well-known manufacturers.
