Full-automatic concrete pressure testing machine is a testing instrument used to determine the compressive strength of building materials such as brick, stone, and concrete. Be sure to read the instructions carefully before use. It is operated by ** experimental personnel to avoid injury caused by improper operation. For more information, please contact our customer service staff.
Fully-automatic concrete pressure testing machine conforms to the ** standard "Standard for Experimental Methods of Mechanical Performance of Common Concrete", automatically controls the loading speed, and has a loading speed display window, peak hold, and overload protection functions. Provided by Shanghai Rongjida Instrument Technology Co., Ltd. The equipment warranty period is one year. If the product has quality problems within one year, the supplier is responsible for free maintenance. If due to improper operation or man-made damage, our company should also provide repair and replacement services, and the costs incurred by our company will be charged as appropriate.
The automatic concrete pressure testing machine is to manually adjust the distance between the upper and lower pressure plates, and the hydraulic loading has a microcomputer display calculation and storage function to print data reports. Greatly reduced the failure rate. Imported proportional valve, high stability and stable loading speed.

Precautions for use and operation of automatic concrete pressure testing machine
★ Before use, check whether the oil in the fuel tank is sufficient. You can check the oil level on the right side. If it is insufficient, you should open the rear tank plate and add it to the fuel tank.
★ Check whether the oil fittings and fasteners are loose, and tighten them if they are loose. Check that the dust cover is intact. Check whether the safety protection measures such as electrical grounding and fuse are effective.
★ When used once, the oil return valve should be opened, closed, and the power should be turned on. Press the start button to start the oil pump, then close the oil return valve, slowly open the oil delivery valve, and the piston rises a distance. No jams and so on. If there is, it should be unloaded, stopped and checked, and excluded. Open the oil return valve and the piston descends to its original position.
★ Wipe the surface of the test piece clean and check for obvious defects in the appearance. If it can affect the test value, replace the non-destructive test piece.
★ Position the wire frame of the lower plate of the test piece in the middle of the lower plate. According to the size of the test piece, turn the handwheel and the screw to adjust the upper plate to the proper position.
★ Turn on the power of the measurement and control system (the switch is on the back of the measurement and control box), and follow the operation steps to clear the data and modify the clock.
★ Press the start button, close the oil return valve, regulate the oil delivery valve, and perform the loading test smoothly at the required rate until the test piece is crushed and the load is reduced. The oil return valve is then opened, allowing the oil to quickly flow back to the tank.
★ At the end of the test, press the "Print" key on the panel. The printer can print out the test report.
★ During operation, the height of the lower platen must not exceed 4cm (or the marking line on the column) to avoid accidents.
★ It is forbidden to place any part of the human body, such as hands, between the upper and lower pressure plates during operation, and pay attention to the fragmentation of the test piece when it is broken to hurt people.
★ After the test, the broken test block is cleared for the next test. When no longer doing the test, open the oil return valve, close the oil supply valve, and cut off the power.
