Summarize:

DKH185 composite hydraulic pressure source (appearance patent has been declared) adopts new aviation composite sealing materials and aviation process structure, creating high reliability and long life (the average service life of aviation composite seals can reach more than 30 years), zero leakage, and no leakage. maintain. The pressure adjustment range is wide, and the pressure rise and fall are stable. The piping has no external appearance, and the system has no one-way valve, which is not affected by the pollution of the meter being checked, and there will never be plugging, leakage, and no pressure. It also has the function of generating negative pressure. Mainly used to calibrate pressure sensors, pressure transmitters, precision pressure gauges, ordinary pressure gauges, oil-free pressure gauges, etc. The system cavity is all anti-corrosion materials, and the pressure transmission medium can be ordinary water. It has been applied to aviation ground handling inspection, aerospace metrology and other institutions.

 Functional characteristics: 

1. Easy operation, labor-saving, wide pressure range, uniform lifting;

2. The system has no one-way valve and is maintenance-free;

3. The use of aviation composite sealing materials and technology, the use of pressure up to 70Mpa;

4. The output port is equipped with a cut-off valve, which can be used for pressure holding test;

5. Each outlet has a filter screen, prevent impurities into the pollution;

6. light weight, reasonable volume, but also convenient field pressure calibration;

7. The use of large piston prepressure, the boy plug pressurization principle.
