Product Description
I. TDYE-300DZ series cement bending and compression machine main uses:
1, the testing machine is suitable for testing 100×100×400(mm), 150×150×550(mm) concrete test flexural strength and cement, mortar and other building materials compressive strength.
2, this machine product according to the pressure mode can be divided into electric hydraulic and electro-hydraulic servo (constant load), according to the control system configuration can be divided into: digital display type (S), liquid explicit (Y), computers (D), cement compressive flexural and cement together (Z) four categories, is a construction, building materials, roads, Bridges and other units of the necessary test equipment.
3, the testing machine conforms to GB/T50081- 2002 "normal concrete mechanical properties test method standard", should start to control the loading speed, and has the loading speed indicator device, in the test process can be uniform continuous loading, and with two equal load at the same time under the action of specimen span three points at the flexural test device.
4, according to the national standard GB/T5008- 2002 "ordinary concrete mechanical properties test method standard" in the process of detection, specimen close to the destruction, should stop adjusting the test oil valve, until the specimen is destroyed, Then, the failure load value and the fracture position of the lower edge of the specimen were recorded. For foreign test standards, please refer to ASTM C109,ASTM C348,ASTM C349,EN 1015,EN 13813,EN 13892-3,EN 12504-1,EN 993-5, and ISO 679.

18. Net weight: 400Kg
Three, TDYE-300DZ series cement bending and compression machine structure principle:
The testing machine is mainly composed of support, hydraulic control box, instrument force display, electrical system.
1. Body part
Machine body measure, columns, and bending device, cylinder body, frame, base plate, measuring instrument installed in a rack on the right side of the upper part, hydraulic action part installed at the bottom of the frame on the right side, under the bending device Installed on the top of the piston, guide plate, on both sides to keep bending under the table motion position unchanged, flexural counter with a ruler, two guide plates on both sides, Can be arbitrary adjust flexural span, kun can up and down activities, the balance of force when can play role, under the equilibrium quantity is equipped with the bending device, two pillar of positioning by turning his head bolt fixed under the crossbar, ball head, ball seat, during bolt bending device is equipped with a spring in order to balance, kun can up and down activities, flexural experiment based on the surface of the specimen, automatically adjust the position, Make the arc surface of the indenter and the specimen into a straight line to ensure the accuracy of the test. On the oil cylinder and flat, with a shield, prevent or reduce the piston rises and falls, dust into between piston and cylinder, and make the both accelerated wear, compressive strength, as long as in the middle of the bending machine surface, put under compression block and clamp, removed under the beam bending device, can be the compressive experiment with seal between the piston and cylinder, can prevent the oil spill, There is a ring groove at the top of the cylinder, and there is a leakage channel, through the plastic pipe, the oil overflow back to the tank.
2. Hydraulic control part
The control box of the testing machine is mainly mailbox, hydraulic oil filter, motor, speed valve, oil return valve, open the oil valve piston slowly rise.
3. Read the force measuring instrument for details (instrument manual)
4. Electrical system
It is composed of control system, motor, start button, stop button, AC contactor, etc.
4. Installation and commissioning of TDYE-300DZ series cement bending and compression integrated machine:
The testing machine installation foundation should be firm and reliable, position to adapt to the operation and make the correct value, the foundation can be appropriate higher than the ground, height according to the actual need to determine, the testing machine should be left around the space of not less than 0.7m, to facilitate maintenance and operation, anchor 2 bolts (M12X300mm) should be used twice grouting, Ensure that the bolt is properly installed so that the level of the testing machine should be maintained (levelness is less than or equal to 0.1/1000) 0.1/1000 frame level instrument should be used to measure the plane of the anti-folding table. If the horizontal or vertical level exceeds the provisions, iron padding correction can be added under the bottom plate, and then tighten the anchor bolt, connect the power line. The machine should have grounding safety protection device. Supply voltage variation shall not exceed 10% of rated value.
