How to operate concrete pressure water analyzer

:

The operation of the concrete pressure water eliminator is crucial, the steps are as follows:

1

Open the top cover of the concrete pressure bleeding device, put the bismuth mixture to be tested into the test tube, and insert the cockroach from the periphery to the center.

Second, add the piston, and unscrew the piston's air outlet screw, press the piston to the surface of the concrete, tighten the air outlet screw, and close the upper cover to tighten the nut.

Connect the quick coupling of the hand pump and the jack (see the structure diagram for details)

2

Tighten the manual oil return valve clockwise and pull the manual pump handle to add oil pressure to

30mpa

(the pressure gauge shows the value), at this time the pressure of the piston against the bismuth mixture is

3.0mpa.

3,

When the oil pressure reaches

30Mpa

Immediately open the bleeding valve and connect the bleeding water

1000ml

Inside the cylinder, start timing at the same time, and

10

Seconds and

140

Secondly read the amount of bleeding

V1

with

V140

As the basic data for calculating the bleeding rate.

After obtaining the data, loosen the oil return valve counterclockwise to depressurize the system, remove the upper cover and the test cylinder, place the test tube on the stripper (supplied accessory), cover the top cover, and tighten Two nuts. Tighten the oil return valve in a clockwise direction, pressurize the jack to the crucible and the piston automatically falls off, remove the upper cover and the test cylinder, loosen the return valve, and manually press the jack piston back, one test is over.
