Product introduction:

Mortar penetrometer is an instrument designed by our company based on the industry standard JGJ70-90 "Basic Performance Test Method for Construction Mortar". It is used to determine the impermeability of waterproof mortar, and the comparative test of mortar mixed with waterproofing agent and benchmark mortar is performed. It is designed according to the principle of hydraulic pressure. The pump is driven by an electric motor to apply pressure, and is connected to a pressure vessel, a control valve, and a mold base through a pipeline. The pressure is output by the water pump into the pressure vessel. Then it is transported to each specimen system for loading test. An electric contact pressure gauge and an electric control system are installed in the pipeline. By adjusting the electric contacts in the electric contact pressure gauge, the pressure can be constant pressure test within the specified range of 0.1-1.5MPa.

Third, the operating procedures:

★ During the test, the water pressure starts from 0.2 MPa, and the water pressure is increased by 0.1 MPa every 8 hours, and the upper end of the six test pieces should be observed at any time.

★ When pressure water permeates from the end faces of three of the six test pieces, record the water pressure at this time as the test pressure value, and press the function key "F" to stop.

★ During the test, if you need to know the time set for the test after the automatic boost, press the "D" key, and return to the "C" key.

★ During the test, if there is an abnormal situation that needs to be stopped, press the function key "F".

★ Check the water in the bucket frequently and add water at any time.

★ After the test, turn off the power switch and empty the water in the water storage tank through the drain nozzle.

★ Unscrew the nut of the water injection nozzle, and simultaneously open the cut-off doors of the six test molds No. 1 to 6, and fill the water tank with a funnel.

★ Fill the test mold chassis with water, close the shut-off gates of the six test patterns No. 1 to 6, and open the shut-off gate of the No. 0 water valve.

★ Reliably fasten the test mold with the test piece installed on the instrument.

★ Turn on the power switch, and the number is displayed as "00.000".

★ Set the test pressure value. Press function key "C" to enter "1" and "2" respectively, so that the display shows "PO 120", press "A" to confirm, press "B" to clear and re-enter.

★ Fill the water tank with water.

★ Remove the two different column nuts on the water pump, pull out the upper baffle and the pump plunger, fill the pump with clean water, and then install it in the original direction to start the normal operation.

★ Adjust the electric contact pressure gauge to the position of 1.5 MPa.

★ Turn on the power and turn on the power switch to make the water pump run normally (there should be no shock phenomenon) and observe whether the water from the 6 mold bases is normal until there are no air bubbles.

★ Close the control valves one by one, observe whether the pressure of the pressure gauge rises, eliminate all leakage faults, and make the pressure stable within the adjusted range.

★ According to the standard test method, install the test molds one by one **, and initially cannot be tightened. Open the control valves of each test mold, observe the water leaked from each test mold seat, tighten the nuts, and adjust the electric contact pressure gauge to test pressure according to the requirements And it works.

六、维护和保养：

齿轮箱内应注入一定量的机油，使齿轮浸入机油内1.5公分为宜，在正常使用情况下每年更换一次。水泵的活塞及两个导柱，每天工作前加机油润滑一次，以延长水泵的使用寿命。每次试验完毕后，应将压力容器，管道阀内的水同过排污阀排。试模及试模座檫净，并涂防锈油脂保护。停用期间加盖防尘罩保护。

Five, maintenance and upkeep:

The gearbox should be filled with a certain amount of oil, and the gear should be immersed in the oil for 1.5 cm. It should be replaced once a year under normal use. The piston of the water pump and the two guide posts are lubricated with oil before working every day to extend the service life of the water pump. After each test, the water in the pressure vessel and pipeline valve should be drained through the drain valve. The test mold and the test mold base are cleaned and coated with anti-rust grease. Cover with dust cover during deactivation.
