First, the functional use: The testing machine is mainly used for compressive strength test of brick, stone, cement, concrete and other building materials, mechanical testing can also be used for other materials. This machine adopts hydraulic loading, electronic measuring, digital display with load, loading rate shows the maximum load to maintain, as well as overload protection and power data retention. Implementation of GB / T 50081-2002 standard. Second, the mechanical part 1, the space to the way by hand wheel rotation, adjustment of the compression space. 2, the oil in the hydraulic system inside the tank through the filter oil network is sucked into the oil pump, oil pump pipeline to the delivery valve, sending oil handwheel is turned off, the oil pressure pushed the piston, oil return pipe back into the tank, when sending oil handwheel to open the fluid through the tubing into the working cylinder, pressure tubing back into the tank through the oil return valve body. Third, the control system of the machine adopts hydraulic loading, electronic measuring, with a load figures, loading rate shows the maximum load to maintain, as well as overload protection and power data retention. Figure 2 meter test report, safety devices when the test force of more than 3% of the maximum test force, overload protection, pump motor is stopped Fourth, the technical solutions: the maximum test force kN 4.1 2000 4.2 test force measurement range kN 200-2000 4.3 Test Force showed the relative error ≤ ± 1% 4.4 test force resolution 0.01kN 4.5 hydraulic pump rated pressure 40MPa 4.6 upper and lower bearing plate size φ225mm 300mm 4.7 between the upper and lower plate spacing 320mm 4.8 piston diameter 250mm 4.9 piston stroke 30mm 4.10 Three-phase motor power 0.75 kW 4.11 Dimensions mm 800 × 500 × 1200 2.12 weight 750kg, system configuration list 5.1 testing machine at a 5.2 pressure sensor Ningbo Zhenhai a 5.3 digital controller (fixed host) 5.4 Electrical control system proprietary technology to produce 1 set 5.5 standard shall be accompanied by one set of upper and lower platens (fixed host), quality assurance equipment after the formal acceptance of the ordering party, as the official delivery. Equipment guarantee period of one year from the date of the formal delivery. In the warranty period, the supplier of the equipment appears malfunction timely free maintenance service. Parts of all kinds of non-human damage, time free replacement. Warranty period, equipment failure in the course of the supplier in time to the ordering party services, and actively assist in order to complete the maintenance. , IT and confidentiality of information a technical solution belongs to our technical information, the user should provide the technical information and materials obligation of confidentiality, whether or not the program is adopted, the terms of the long-term; 2 our users IT and information should bear the obligation of confidentiality. Service tenet: fifteen days replacement, two years warranty, lifetime service. Pledge: If the machine fails within one hour to give the phone answered, site service within 48 hours in the province, outside the province 72-hour on-site service.
