Testing Press (IP) is a device that today is one of the most popular in the construction market. The main objective of this equipment is to check the concrete mixture for compression, bending, etc.
General arrangement of presses
Any model of the press has a bed, a traverse, as well as two racks. This is the basis for the whole mechanism as a whole. Another element used in any model is the loading mechanism, which creates pressure on the test object. This element consists of several parts - an electric motor, a converting device and base plates. An oil pump can be used as a converter if it is a hydraulic press or a gearbox with a friction clutch if it is a screw type of equipment.
IP-1000-0
Currently, there are many different devices that are engaged in testing concrete. The advantages of the IP-1000-0 press include the fact that it has very high accuracy, it is quite simple to operate, and also does not require laborious care. The verification technology used by this machine has been tested for years and does not fail.
Specifically, this model belongs to the group of hydraulic test presses. In addition to hydraulics, it has torsion force measurement, and the main task is static tests of concrete grades, which belong to the standard category according to GOST 10180. It can be added that this machine can be used to check not only concrete, but also brick, and several other types materials that are actively used on construction sites.
Testing on the press IP-1000-0
If we talk about the progress of the test and the principles of operation of this particular model, then they are quite traditional for such brands of the test press.
The process of testing a concrete sample is carried out by applying a static load to it. This process is carried out until a complete deformation is observed, that is, the destruction of the test object. The fixed parameters during the test are the loading speed, as well as the change in the load at the facility. The main task for the deformation of concrete lies on the loading device of the apparatus. The test press of this group has instruments that are able to control the deviation of the load speed. Such devices include a displacement transducer and a microammeter located on the remote control. This device shows the operator the percentage deviation from the fixed value.
Small Test Press
Consider the work of this group of devices on the example of models such as MIP-25 and MIP-50. The main purpose of these units, as well as any other small-sized devices, is to conduct operational tests of concrete or other building materials during the examination of the structure. In other words, they can be used directly at the construction site, as they are positioned as mobile units.
These machines can be used to check concrete samples for compression. The sizes of the tested objects can be 100x100x100 mm or 70x70x70 mm.
What are the advantages of MIP
Here are some of the positive qualities that are inherent in such installations:
- The most valuable is the fact that the equipment can be used directly at the facility during its inspection. Application in factory or mobile laboratories is not excluded.
- For the production of such test presses, the latest technologies and materials are used, which made it possible to create equipment that is at the highest level in terms of dimensions, weight and margin of safety. The total mass of the press is only 45 kg, and its strength has a half-time margin.
- You can also add that the design of this device is the latest and patented. The hydraulic power drive is located in the upper part of the machine, there are two drive hydraulic cylinders with a gearbox, as well as a cylindrical bearing body.
- The disadvantage of some test presses is that they “bounce” the moment the concrete collapses. In these models, this is excluded, since the power impulse goes down, where it is compensated by the support of the machine.
- The device has cylindrical moving shutters, which exclude the possibility of flying apart fragments resulting from the destruction of the test object.
- Several models are produced, which differ in their working pressure, it can be up to 250 kN or up to 500 kN. The drive of these units can be either manual type or electric.
Small hydraulic test press
PGM-MG4 devices are intended for testing concrete samples for compression as well as bending. You can test a variety of building materials, but the load speed must be set in accordance with the relevant standard.
For the drive to work, there is an electrical device that connects to a conventional 220 V and 50 Hz network. In addition, there is also a strain gauge force meter. The distinguishing features of these models include the relatively small size, light weight, and silent operation of the electric drive. Since the system uses multi-plunger pumps, there is no ripple in the hydraulic system. This is also facilitated by the use of microprocessor control of the loading process.
Getting Results and Models of PGM
Indication of the test results of a digital type, that is, information is displayed on a graphical display with backlight. In order to enter the source data there is a control panel, the input itself is carried out in the dialog box mode. All results that will be obtained during the test are immediately archived automatically. Archived data is marked with the date of the test, as well as the measurement time. After that, all information is transmitted to the operator’s personal computer. Further, it is possible to document all parameters.
If we talk about the models of the test press, then, for example, PGM-100MG4 and PGM-100MG4A are intended to conduct compression testing of cellular concrete. The presses PGM-500MG4 and PGM-500MG4A were created in order to test all types of concrete grades. Tests are carried out on compression.
Automatic Press
The test press TP-1-1500 is an automatic model. The main purpose of this machine is to determine the tensile strength for various building materials, including concrete, during the test process. A distinctive feature of this type of machine is that it operates in automatic mode. Supply, maintaining the growth of power, withdrawal and calculation of all parameters in accordance with GOST - all these operations are carried out by the equipment without human intervention.
The dimensions of the tested concrete samples can be cubic with a rib length of 70 mm, 100 mm and 150 mm. In addition to testing cubic samples, it is possible to check cylindrical concrete forms for compression with a diameter of 70 mm, 100 mm, 150 mm, 200 mm, 250 mm. It is also worth adding that for the operation of this press, connection to a conventional network with a voltage of 220 V and 50 Hz is suitable. The power that the equipment will consume during operation is 1 kW. The machine is controlled by a computer. The graphic display of such machines is 19 inches. It is worth saying that the mass of the installation is quite large - 460 kg.
