Concrete impervious instrument/concrete impervious instrument operation procedures/automatic regulating concrete impervious instrument
HP - 4.0 concrete impervious instrument
A, applicable scope
Concrete, is now widely used in the construction of artificial stone, for some construction, such as hydraulic construction, underwater, water, underground and other architectural engineering, building requirements has special performance - anti-permeability so-called anti-permeability is refers to the structure of material in use can resist water and/or other liquid (light oil, heavy oil) of the medium pressure infiltration under the action of performance.
HP - 4.0 type impervious instrument is mainly used in lake screw soil anti-permeability and is test and anti-permeability label measurement. At the same time can also be used for building material permeability measurement and quality inspection, so to get the relevant production, construction, the design, the research of various departments such as widely used.
Second, the main technical parameters
1, the maximum working pressure: 4 mpa
2, working ways: automatic constant pressure (digital display type: automatic constant pressure and automatic booster)
3, a can make specimen number: six
4, try die geometry (also called Lord die)
Die cavity flowing diameter: φ 174.8 mm
The mouth cavity diameter: phi 185 mm
Height: 153 mm
5, plunger pump parameters:
Flow: 0.16 L/min
6, motor:
Power: 120 w
Power supply: 380 v - 50 hz
7, physical size: 950 x 800 x 950 mm
8, quality: ≈ 220 kg
Three, the main working principle and its agencies (sees attached figure 1)
HP - 4.0 type impervious instrument is to use airtight container internal pressure is equal principle (waterhead negligence except), with water pump to the whole system to lose pressure, and through the electric contact pressure gauge and pressure controller pressure of the size of the pressure to achieve pressure water from down to up penetration pressed in the mold of the specimen, so as to test specimen anti-permeability and calculate its anti-permeability label of the instrument. HP - 4.0 type concrete impervious instrument is mainly composed of housing, table, the stainless steel panel is made, and install a six mold base and 36 M12 bolt, used for installation of mold.
For pressure system, by the motor, power box, water pump, water bag, relief valve, pipe and other components, motor used to the system to provide the power supply, power box used to motor provides power supply into a back and forth movement of the power supply and water pump, pump to the whole system to provide water, water for bag to stabilize supply system of hydraulic pressure, and the water source, power box used to motor provides power supply into a back and forth movement of the power and supply water pressure, and the water source of the shunt effect; The relief valve installation word water bag central, the role of the safety valve is to ensure that the system pressure is not more than 4 mpa4, work station, mainly by the electric control and control valve composition.
HP - 4.0 type concrete impervious instrument electric control section (sees attached figure 2), the red green button switch and one electric contact pressure gauge composed,
Green button to start switch, red button to stop switch, electric contact pressure gauge used to control system for pressure the pressure to remain in you need range and, when the pressure pointer to the limit, pump stop work, because specimen penetration and other reasons, the hydraulic pressure drop, pointer anti-clockwise rotation, leave the upper limit position, until the lower reach, a water pump restart, hydraulic pressure rise to cap a (2) control valve. The open and closed and general valve are the same, namely clockwise to relationship, anti-clockwise rotation for open, each valve corresponding control a try die,
HP - 4.0 type digital display concrete impervious instrument electric controlling part: the combination switch and one pressure sensor connection of the controller. Combination switch control impervious instrument source, "0" position close "1" for the open position; Controller term control for pressure system pressure to remain in the scope of you need. About the operation of the controller that see appendix "digital display anti-permeability meter pressure controller operation instructions"
Four, installation and use
1, ready to
A, will anti-permeability instruments on the level off, solid indoor basis,
B, closing is located in the lower right of the water pressure relief valve
C, open six control valve
D, first use, water injection into the box and open the valve, starting power supply, and 6 mold base internal water overflow so far, in order to discharge the air inside the system.
E, close control valve
2, sample production and installation
A, specimen forming curing, according to the design requirements of the ratio of materials with mold (also called vice die) making forming, and then press department or the international standard for cover.
B, and curing good specimen surface dried, then in its side TuShan melting sealing materials (sealing wax or sealing wax) note specimen two face, forbidden coated with sealing material.
C, will try to die heating to 40 ℃, then coated with seal material specimen into cavity, and then in the press (screw press or borrow laboratory pressure testing machine) will test pressure into the test mould and cooling to room temperature, it is best to use the factory supporting the production of HT - 200 type multifunction stripper, already but outfit, release, and splitting specimen, observation
Water penetration depth.
D, will put pressure good specimen trial die installed in impervious instrument work on stage, and even tighten the screw nut
3, switch on the power, the red light two, the electric contact pressure gauge cap pointer adjustment to 0.1 MPA floor pointer and the reliable near but not at the same time contact (about 0.05 MPA is less than the limit pointer), and then press the green button to start power supply, the water pump to work, electric contact pressure gauge pointer with hydraulic pressure rise and clockwise rotation, attention to the observation of pressure rise is normal or not, the system for permeability
