Use a screwdriver to unscrew the screw fixing the rear cover and remove the rear cover, to φ40mm hole locations on the tank cover and fill the machinery oil; fuel injection in order to reach the oil standard central location is appropriate; Close the lid after filling is completed. Note: When the ambient temperature of 15 ± 5 ℃, the use of GB443-84N68 machine oil when the ambient temperature of 25 ± 5 ℃, the use of GB443-84N100 machine oil (2) electrically coupled to random power plug in the appropriate outlet. Power is 380V 50Hz. (3) Start the pump exhaust oil return valve is opened, delivery valve open. Turning the machine off, then the screen was random state. Press the "start" button, Henan asphalt penetration instrument, start the motor, the pump began to work, continue to work after about a minute to close the oil return valve, this time can be found to rise slowly lower platen, Zhengzhou asphalt penetration instrument, the lower platen rise to about 20mm when closed delivery valve and open the oil return valve, when in the down state of the lower platen. Repeat the above steps 3 to 4 times the gas within the system can be completely ruled out. Concrete test equipment operating concrete test instrument to use is very important, if errors in operation will give you cause unnecessary trouble, as well as strict control of the use of its unique structure, twin concrete test equipment with high mixing efficiency, mixing things more uniform discharge cleaner and so on. Here there are a few steps to use concrete testing equipment: for construction-related scientific research, design departments and laboratories and construction unit used to measure the deformation of shrinkage and expansion of concrete. Shrinkage of concrete expansion instrument from the base, positioning column, adjustable column, dial indicator, par and so on. 1, the base for the steel unit, for receiving the test block with concrete. 2, positioning column for par and concrete brick probe on the left side of the vertical and horizontal spacing. 3, adjustable column, its commercial port there are three pre-installed through holes dial indicator dial indicator positioning and help set screws. Three through holes respectively from the base plane 50mm, Henan standard curing equipment and instruments, 75mm, 100mm 50mm aperture plane from the base for measuring 100 × 100 × 515 specifications of concrete brick; 75mm holes from the base plane, for measuring 150 × 150 × 515 specification concrete test blocks (due to tryout specification only 150 × 150 × 600, should Proposed Use tryout shorten pieces, instruments, so that concrete brick forming size becomes 150 × 150 × 515) . 4, par, as a baseline length of the instrument. The factory has been installed on par par shelf, do not free entry, so as not to affect the degree of accuracy par Center. 50,75100 words each side of par, showing where on the base as a reference surface, the high standard rush Center 9 are 50mm, 75mm, 100mm.
