First, use

Pressure bleed water meter is test pumping concrete in the secretion of water under certain pressure conditions, and thus calculate the bleeding rate than a special instrument, I plant the production SY-2 concrete pressure bleeding device, the measured value is accurate, easy to operate , small size, light weight, demoulding convenience, the various technical indicators to the national JC473-92 standard.

The instrument is mainly by hydraulic jacks, pressure gauges and superstructure piston test cylinder, the base composition.

Third, the use

1, open the cover, you will need to test concrete mixture into the test cylinder plug pound pound rod from the periphery to the center 25 times, coupled with the piston, the piston and the vent screw under pressure piston to new to the concrete surface, tighten the vent screw, the upper cover to pull the nut, take a good manual pump jack quick connector (see structure diagram)

2, then clockwise twist tight manually jump back to the oil valve, pulled the handle of the hand pump, oil pressure will increase to 30mpa (gauge shows value), the piston on the concrete mixture pressure 3.0mpa.

3, when the oil pressure reach 30Mpa, immediately open the bleeding valve, start timing and secretion of water access 1000ml graduated cylinder and read in 10 seconds and 140 seconds, respectively, V1 and V140 of the secretion of water, calculated on the secretion The basic water rate data.

To obtain the data counterclockwise loosen the oil return valve, the system pressure relief, remove the lid and test barrel, the test cylinder is placed in a mold release (random attachment), the upper cover. Tighten the two nuts. Twist in a clockwise direction tight oil return valve and pressure to the jack to the concrete and the piston automatically fall off, remove lid and test barrel, loosen the oil return valve, manual pressure to return to the jack piston, one end of the trial.

Fourth, the care and maintenance

1, the end of each test to the instrument with water rinse and dry, such as long-term do not to anoint rust will not paint the surface of the part.

2, during installation, the test cylinder shall not be reversed, the lower end of the outside coated with a little grease to make it able to successfully insert the base, and "0" ring seal.

3, such as the pump but the oil resulting in pressure do not increase, the pump can be opened up the back, press the hexagon socket head bolts to join the 20th oil and re-installed to.

Five jack to use

1, the quick connector on the pump rubber hose pulled back again and jack connectors with Then tighten the valve stem back to the oil pump and jack handle on the pull-down pressure, that is used. Work after the screws at the same time to relax and make restitution.

Pump For refueling, should remove the tail of the rubber cover and M8 socket head cap screws, exposing the tubing to fuel oil must be clean.

3, then long tube to make a number of lift, the need to use the appropriate length and head.
