1、 Purpose and Characteristics

KQM-III Series end quenching testing machineCompared with ordinary end quenching testing machines, improvements have been made in the following aspects to make it moreHigh tech content.stability、*Far ahead of traditional products, it is also more convenient for users to use.

Adopting a digital quenching time control system, it can automatically start up-automatic sprinkler-quenching-End the entire working cycle of the alarm, and the overall design layout is reasonable, compact, easy to use, and convenient for maintenance and repair.

Key Features:

1. The testing machine consists of a frame, high and low water tanks, an automatic water circulation system for water pumps, a water spray time setting system, an automatic quick opening device for nozzle baffles, and a water temperature regulation control system.

2. Complete testing machine（water tankNozzle bracket rack panel shelf）adopt J304 Stainless steel welding, water tanks, nozzles, etcComponents that come into long-term contact with water are used 1Cr18Ni9Ti Made of stainless steel.

3. The control of the water spray start function adopts two methods: automatic control and manual control using high-sensitivity photoelectric sensors (standard is manual control).

4. The time control adopts high-precision digital display time relay with time sound alarm function. After reaching the set time, the water blocking plate is installedIt will automatically shut down. The spraying time of each nozzle can be set separately, and the spraying height can be adjusted separately to maintain the stability of the water column.

5. The water temperature control adopts compressor refrigeration and heating rod heating. The water temperature control accuracy is high, and the water tank is equipped with temperature control instruments.

6. The various measuring instruments used and installed are easy to disassemble for inspection.

7. Install inlet and outlet pipes, with inlet pipe diameter 6 in charge of.

8. The alignment between the inner hole of the sample holder and the nozzle is stable and easy to adjust (equipped with an important center height adjuster).
