Overview
DVP-90 high-speed Vacuumpump is a product of Yonghao vacuum brand. It adopts high-speed direct-coupled vane design and is positioned for stability with few parts, high reliability, silence and extremely high Ultimate vacuum degree. Through the integral pump structure, forced oil pump lubrication control system, all-round exhaust system and special air ballast valve, it ensures reliability under different operating conditions.
Features
1. Ultimate vacuum degree
2. Unique exhaust device
3. Special gas ballast valve design to accelerate the extraction of steam without polluting the oil quality
4. Built-in air inlet check valve system to protect the vacuum system and avoid oil contamination
5. Constant pressure oil circulation oil supply system protection
6. Small number of parts, easy to repair and maintain
7. Extremely low noise
Principle
The pump adopts a high-speed direct-coupled rotary vane design, which realizes efficient air extraction through an integrated pump body structure, a forced oil pump lubrication control system and an all-round exhaust system. Special gas ballast valves are used to accelerate the extraction of steam, keep the oil clean, and ensure stable operation under different conditions.
Applications
Chemical, freezing, drying, Encasement, adsorption, coating, photovoltaic supporting, semiconductor, electronics, food hygiene, printing, Pottery and porcelain supporting, scientific research, Universities & colleges laboratories, laboratories, refrigerator assembly lines, air conditioners, water dispenser automatic control lines, lighting, Vacuum oven, freeze dryer, double row tube, tube furnace, glove box, Rotary evaporator, centrifugal condenser, cleaning machine, various high vacuum front pump, suctionfiltration, coating, sputtering equipment
Steps
1. Power frequency is 380V
2. Connect the air inlet and air outlet interface (KF-40)
3. Add an appropriate amount of pump oil (oil capacity 5.5L)
4. Start the pump, monitor the speed and noise
5. Adjust the gas ballast valve settings as required
6. When stopping work, ensure that the built-in check valve protection system
Notice
• Power frequency matching 380V
• Regularly check the pump oil volume and oil quality to avoid contamination
• Monitor the pump oil temperature rise, no more than 45 ° C
• Protect the vacuum system with a built-in check valve after stopping work
• Keep the exhaust system open to prevent blockage
• Pay attention to the noise level and ensure that it is below 58dB (A)
• Regular maintenance and maintenance to ensure that parts are in good condition
