0.3PA Vacuum Pump Rotary Vane Two-Stage Commercial 110V 7CFM 3L

<p>Introduction:<br>&lt;br&gt;The rotary vane vacuum pump is the basic equipment used to extract gas from the airtight container. It can be used alone or as the pre-pumping pump of booster pump, diffusion pump, molecular pump, maintenance pump and titanium pump. It can be used for the manufacture of electric vacuum devices, vacuum welding, printing, plastic absorption, refrigeration equipment repair and instrument matching. The dual-stage vacuum pump is small in size and light in weight, and has a large oil window for easy observation of oil volume even when adding oil. The oil mist catcher has the advantages of five-layer filtration, effective prevention of oil smoke splashing and noise reduction.<br>&lt;br&gt;Operating Instruction:<br>&lt;br&gt;Check the oil level and fill the oil to the center of the oil pointer when the pump is stopped. If it is too low, it will not seal the exhaust valve and affect the vacuum degree. If it is too high, it may cause fuel injection during atmospheric starting. It is normal for the oil level to rise during operation. Oil is added from the oil filling hole, and the screw plug shall be screwed on after filling. The oil should be filtered to prevent sundries from entering and blocking the oil hole.<br>&lt;br&gt;The pump can be started at one time under atmospheric or any vacuum. If a solenoid valve is installed at the pump port, it should act simultaneously with the pump.<br>&lt;br&gt;When the ambient temperature is too high, the temperature of the oil will increase, the viscosity will decrease, and the saturated vapor pressure will increase, which will cause the limit vacuum to decrease, especially the total pressure measured by the thermocouple. If the ventilation and heat dissipation are strengthened or the pump oil performance is improved, the limit vacuum can be improved.<br>&lt;br&gt;Check the limit vacuum of the pump based on the compressed mercury vacuum gauge. If the vacuum gauge has been fully pre-pumped and calibrated, the pump temperature is stable, the pump port is directly connected with the gauge, and the limit vacuum will be reached within 30 minutes of operation. The value measured by the total pressure gauge is related to the pump oil, vacuum gauge and gauge error, sometimes the error can be even large, and can only be used as a reference.<br>&lt;br&gt;If the relative temperature is high, or the extracted gas contains more condensable steam, open the gas ballast valve after connecting the extracted container, and close the gas ballast valve after 20-40 minutes of operation. Before stopping the pump, the gas ballast valve can be opened for 30 minutes without load to extend the service life of the pump oil.<br>&lt;br&gt;<br>&lt;br&gt;Parameters:<br>&lt;br&gt;Type: 2RS-3<br>&lt;br&gt;Voltage: 110V/60HZ<br>&lt;br&gt;Free Air Displacement: 7CFM<br>&lt;br&gt;Ultimate Vacuum: 3*10-1PA<br>&lt;br&gt;Power: 3/4HP<br>&lt;br&gt;Rotating Speed: 1720R/MIN<br>&lt;br&gt;Oil Capacity: 370ML<br>&lt;br&gt;Packing Size: 17.7*8.1*12.2"(45*20.5*31CM)<br>&lt;br&gt;Net Weight: 24.2LBS/11KG<br>&lt;br&gt;Gross Weight: 25.2LBS/11.6KG<br>&lt;br&gt;<br>&lt;br&gt;Items Included: 160800-EnzY<br>&lt;br&gt;110V 7CFM Vacuum Pump</p>

• The oil mist catcher has the advantages of five-layer filtration, effective prevention of oil smoke splashing and noise reduction.
• With gas ball valve device to prevent pump oil from mixing and prolong oil pumping time. Anti-return oil,anti-leakage oil and environmental protection The pump can be used as an air pump alone, and it can also be used as a fore-stage pump of a booster pump, a diffusion pump, a molecular pump, It also can be the pre-pump of the titanium pumps.
• Using copper wire multi-layer winding motor,stable to provide high power output,durable than ordinary motor,long service life.
• Double-stage high-speed direct-connected rotary vane vacuum pump. The dual-stage vacuum pump is small in size and light in weight, low noise, easy start, and has a large oil window for easy observation of oil volume even when adding oil.
• The rotary vane vacuum pump is the basic equipment used to extract gas from the airtight container.It can be used for the manufacture of electric vacuum devices, vacuum welding, printing, plastic absorption, refrigeration equipment repair and instrument matching, medical analysis equipment, especially lithium bromide, air conditioners, hail and other refrigeration industries.
