Concrete compression tester is a kind of compression testing machine. Mainly used for concrete testing, cement, high strength brick, refractory materials and other building materials test block compressive strength can also be used for other non-metallic materials, the compressive strength of the test.
TSY-2000 Concrete Compression Tester
Concrete Compression Tester Structure
It is mainly composed of main machine, hydraulic system and force measuring unit.
1.Main Machine
Mainly by the beam, column, adjust the screw and hand wheel, bearing plate, cylinder and piston and other components. Between the end of the screw and the upper platen, the movable ball seat is installed. When the bottom surface of the upper platen is in contact with the top surface of the specimen, it can automatically adapt to the slight inclination of the specimen in the height direction, so that the two planes are in contact with each other, Force evenly. According to the specimen size, you can turn the hand wheel and screw to adjust the test space.
A positioning wireframe is arranged on the top surface of the lower pressing plate, so that the specimen can be placed in the central position.
2.Hydraulic System
It is composed of hydraulic pump, oil delivery valve, return valve, oil tank, oil filter and oil pipe.
The hydraulic pump is an axial five plunger super high pressure pump, driven by an electric motor directly. The delivery valve is provided with a safety valve, and the overload is over flowing, and the utility model has the safety function. Operate the oil supply valve handwheel to adjust the oil intake of the cylinder so as to achieve the required loading rate. Turn on the return valve and return all the oil from the cylinder and the oil pump back into the tank.
3.Force Measuring Unit
It mainly includes measurement and control system, printer and pressure sensor.
4.Electrical System
It consists of an electric motor, a starting button, a stop button, an alternating current contactor and a fuse.
Semi-automatic Concrete Compression Tester
Concrete Compression Tester Installation and Trial Run
Concrete compression tester should be installed horizontally on a solid foundation with a level of 0.2/1000. Test machine should be no less than 0.8m distance from the wall, there should be sufficient testing around the required range of activities and channels, four foundation screw (M10*300) should be used two times grouting to ensure the accuracy of bolt buried position. See the installation basic drawing of the basic plane of the machine.
The machine shall be used in the condition of no corrosive medium and no vibration, and the fluctuation range of the supply voltage shall not exceed 10% of the rated voltage. Local electric safety protection device shall be provided. Due to the use of hydraulic oil, there should be safety precautions around.
After the laboratory equipment is stable, the measurement and control system is installed in the corresponding parts of the top of the box on the right, and then the sensors and wires are plugged in.
Fully Automatic Concrete Compression Tester
Concrete Compression Tester Attentions
1. Before use, should check the tank is sufficient oil, can look at the right side of the oil standard, such as insufficient, it should open the rear box board to add to the tank, to the liquid level at the oil mark is appropriate.
2.Check the oil filling joints and fasteners are loose, if loose, then tighten it. Check that the dust cover should be intact. Check the electrical grounding, fuse and other safety measures are effective.
3.For the first time, should the oil return valve to open and close the oil valve, switch on the power, press the start button, the pump starts to work, and then close the valve open to sending oil valve, the piston rises at a distance, there is no failure. If there is, it should be unloaded, stop inspection, and ruled out. Turn on the return valve, and the piston drops to its original position.
4. Clean the surface of the test piece and check for any obvious defects. If you can affect the test value, you must replace the nondestructive test piece.

Concrete Compression Tester Maintenance
1.The testing machine should be kept clean and tidy inside and outside, to prevent corrosion of each department.
2. Always check whether the oil is clean or not. In general, at least once a week from the drain release tank precipitation oil once, depending on the amount of oil pollution, until the release of oil without dirt so far. The regular user should remove, check and clean the oil filter once a month. If the dirt is blocked seriously or damaged, the oil filter must be replaced.
3. Frequent use, every six months need oil change. At the same time, thoroughly clean the fuel tank, oil filter and oil filter net with kerosene. And repeated several times until the wash, use the towel to wipe the bottom, then poured into cleaning oil. If the oil is found to be cloudy and cannot be reused, it should be replaced immediately.
4. Hydraulic oil specifications, depending on the test room temperature varies, it is recommended as follows:
When the room temperature is lower than 20 degrees, the use of GB7631.1-87 anti-wear hydraulic oil L-HM46 (its viscosity equivalent to the old brand No. 30)
When the room temperature is higher than 20 degrees, the use of GB7631.1-87 anti-wear hydraulic oil L-HM68 (its viscosity equivalent to the old brand No. 40)When not in use, plastic cover, machine cover good.
When not in use, plastic cover, machine cover good.
