Description of Hydraulic dead weight tester
DK dead weight tester is designed on the base of YS piston dead
weight tester and KY Deadweight Tester, with structural
optimization, super wear-resistant and perfect reliability. The
highest process of DK piston dead weight tester is 0.005%; The max
pressure range is 160MPa. DK dead weight tester adopt modular
structure, a platform can be installed in different piston systems,
achieve economic and practical purposes.

Feature of piston hydraulic dead weight tester
1. High accuracy.
2. Professional manufacturer
3. Max pressure up to 300mpa
4. Fast delivery.
5. Factory price
Installation of piston hydraulic dead weight tester
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 of piston hydraulic dead weight tester
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.
