DK Dead Weight Pressure Gauge Tester Stainless Steel

The description of the pressure gauge calibrator piston water dead weight tester:

Pressure gauge calibrator piston water dead weight tester as a basic instrument to transfer pressure value, easy to use, simple structure, light
weight, we developed DK piston DWT, uncertainty can reach to
one in one per million.

water piston Dead-weight tester specification

1,Piston system adopts special tungsten carbide material, with
better hardness and intensity than traditional tungsten carbide
material.
2,The weights adopt non-magnetic stainless steel, fully considering the influence of the uncertainty of the earth's magnetic field on the piston.
3,Prepressurization without pressure cut-off valve, operation
more convenient.
 

4,The whole machine are of stainless steel material, panel after
grinding and cutting, with beautiful appearance.
5,Piston position with a low center of gravity, low altitude, the
piston run more smoothly.
6,Piston pressurized part can be completely without hand
rocker, a hand wheel added to the highest pressure.
7,Internal check valve, soft seal structure, better air tightness.

The components of the pressure gauge calibrator piston water dead weight tester:

1,Pressure export joint 2,Piston system joint 3,Pressure export joint 4,Pressurized cylinder
5,pressure relief valve 6,Pre pressurization system (oil filled) 7,Oil cup cover

Installation:

1.Piston pressure handwheel fixed by 2 pcs hexagonal screws, to delivery convenient client can install it when receive the product.
2.Piston foot has been installed, it can directly put on the table.

Operation steps:

1. Leveling: adjust the piston feet, let the level bubble to the center position.
2. Refueling: Open oil cup cover (see illustration 7), refueling.
3. Fitted pressure gauge: install pressure gauge or other instrument on the joint 3 or joint 1.
4. Place weight: place weights on 2 position.
5. Open the pressure relief valve 5, rotate Pressurized cylinder
4. to the outermost end.
6. Close the pressure relief valve.
7. Add Pressure: with Pre pressurization system 6, gently press a few times, feeling slightly resistance is ok.
8. Using pressure lever 4 to the piston system rises, rising to the piston system (after rising need rotary piston system, so that the piston system always keeps spinning).
9. Below Piston system 2 has aluminum ruler, the equilibrium position is between upline and downline.

Maintenance:

1. The piston DWT is free maintenance product, can replace the matched seal ring when with breakdown and leakage.
2. The medium must be clean.
3. If the piston rotation time is shortened, can clean the piston system and clear impurities.
4. The piston structure is very simple, but very durable, can remove with common use tools.
