Besides the fact that people need water, the body is also very demanding on the quality of this product. It is for this reason that small-sized drilling rigs are becoming more widely used. This is due to the fact that using this installation, it is possible to extract water from underground sources that have not yet been contaminated.
Installation device
The main advantage of a small-sized drilling rig is that it can be used without hiring specialists. Installation, configuration and further operation of the unit are quite simple, and therefore almost anyone can cope with it. The equipment consists of the following main elements:
- Drilling barrel with a liner. These two parts are essential for installing the fixture. Due to the fact that this is the only support of the installation, it is necessary to carry out installation only on the terrain that was previously well-compacted so that the drill does not sag.
- Further, there is a drill nozzle, which is a key element that conducts all drilling operations.
- An additional device is a conical lock. This element is designed to be able to remove and change the drill bit if the situation requires it.
- As the guiding mechanisms, side drains are used, which set the direction of movement for the drill.
- The small-sized drilling rig is equipped with a very durable winch, which is responsible for lowering the drill to a depth.
- The heart of the equipment is an electric motor that converts kinetic energy into rotational and translational motion of the drill.
- The machine control panel is equipped with only two buttons - on / off. There is protection against moisture, and therefore it can not be covered with anything, even if it remained in the open.
Additional work
The weight of a small-sized drilling rig never exceeds 30 kg, which allows it to be transported using a car. Sale of goods is carried out already assembled, and therefore it is only necessary to prepare the site and install the device. Most often it takes about an hour. However, if the soil is rather problematic or weak, then much more can go.
Settings Parameters
It is important to understand that the design of small-sized drilling rigs is a complex of equipment. The choice of a particular complex depends on what type of soil you have to work with, as well as on a factor such as a geological section. The most compact units with a low weight lend themselves perfectly to assembly and disassembly. Two workers can cope with this task. The temperature range in which the operation of the device is allowed is from -30 to +40 degrees Celsius. It is also important to note here that the design of the device and the power of the electric motor - 2-3 kW - allow connecting the equipment to a regular 220 V network. In addition, there is a certain division into classes, depending on the method used for drilling. It can be rotational, shock, complex and several other types.
Models and Features
Small-sized drilling rigs of the RB-50/220 series. These devices can come with 1, 1.5 and 1.8 meter rods. Their diameter is 48 mm, and the main material for the production is steel grade St40X. The drilling depth of such installations is in the range from 50 to 70 meters in the presence of an electric motor with a capacity of 2.2 kW. Experts recommend additionally supplying the machine with a mud pump. The main purpose of the unit is to work with soil, which contains solid particles up to 20 mm in size.
Small-sized drilling rigs for water series RB-100/380. These units are more powerful representatives of the same class. To supply them, a 380 V generator is needed. The depth of the well that the equipment is capable of drilling is 100 meters. The electric motor power in cars is 4.4 kW. Another necessary condition for the operation of such a plant is the presence of a mud pump with parameters of 900 l / min.
The main positive and negative qualities of MGBU
Small-sized water drilling rigs are considered the most popular product among stationary and self-propelled types of machines. The advantage of a mini-installation over these types is the following:
- Possibility of simple and convenient transportation, as well as small dimensions of the assembled product.
- The operation process does not require special attention, the repair and maintenance of the machine is quite simple, these works are performed at the drilling site.
- The ability to use the unit in those places where there is a limited area.
- The rather low cost of the device, when compared with stationary or self-propelled types.
- It is possible to carry out all work, having on the site even non-professional workers. The number of required personnel is 2 people.
Among the disadvantages, it is worth highlighting that the average engine power is quite low, and therefore drilling a well with a depth of more than 100 meters is impossible.
Equipment Prices
It is worth noting that the price of a small-sized installation depends not only on technical parameters and operational characteristics, but also on the model of the device. In addition, the process of value formation is carried out on contractual terms.
For example, a series of RB model 50/220 V will cost around 59 thousand rubles. A model of the same series, but powered by a 380 V network, and having the ability to drill a well 100 meters deep, will cost 119 thousand rubles.
If we talk about the installations that belong to the UKB-12/25 series, as well as about all the modifications available for these units, they work not only from electric motors, but also from gasoline. This greatly expands the possibility of their application. However, along with this, the cost of the unit increases significantly. The approximate price of such a model for drilling wells is 215 thousand rubles.
A small-sized drilling rig for drilling used water wells, of course, will cost less. However, buying a device in this way, it should be understood that it has already served a certain period and, most likely, will soon fail.
