Oil hydrualic piston dead weight tester for pressure gauge

1. It adopts welded structure, there is no influence of vibration on air tightness, and air tightness is very good.

2. The piston rod adopts special tungsten carbide, which not only ensures the hardness of the piston system, but also ensures the toughness of the piston system to the greatest extent.
3. Lever piston gauge use of protective structure, the protective shank diameter 10.03 mm, 10.06 mm diameter of the protective tube, when the swing piston gauge and misuse protection device protects the rod against damage, greatly strengthened piston gauge Practicality and convenience. (Core technology is the first in China)
4. The piston type pressure gauge is installed in the piston type pressure gauge protection device, and no special tools are needed, which is convenient for the customer to install and clean.
5. The displacement system of the piston type pressure gauge is indicated by a color change indicator. When the lower limit of the piston is red, the color of the indicator light turns yellow when the position is balanced, and the red light is on when the upper limit is displayed. A color change indicator can achieve this function. The first in China).
6, from the original amount of displacement of the piston rod of 3 mm to 5 mm now larger amplitude movements of the piston, longer stability, and practical measurement is more suitable for mass production.
7. The countertop is made of stainless steel countertop (0.02 grade). The countertop is clean and tidy, no additional equipment is available for convenient maintenance.
8. The piston type pressure gauge no longer adopts the hanging blue structure and adopts the ground structure. It is more convenient to place the weight with one hand.
9. A series of improvements of JQ pistons are for practical purposes. In the development of piston systems, how to use them is not easy to break. How to place weights is convenient. I hope this piston can make metering more convenient.
