< It is a double-stage high-speed direct-coupled structure rotary vane vacuum pump, hereinafter referred to as the pump. It has a rotor installed eccentrically in the pump chamber and a rotary vane in the rotor slot. When the rotor is driven to rotate, the rotor blades are close to the cavity wall, separating the intake and exhaust ports, and the volume of the intake cavity is periodically expanded to suck in air, while the volume of the exhaust cavity is periodically reduced to compress the gas. , push the exhaust valve to exhaust, thereby obtaining a vacuum. Figure 1 is a schematic diagram of the working principle of a single-stage pump. The double stage is composed of two single stages connected in series.
Type
< Rotary vane vacuum pump
< Equipped with a gas ballast valve, which has the function of extending the use time of the pump oil and preventing the pump oil from mixing with water.
Type
< Rotary vane vacuum pump
< It has the advantages of small size, light weight, low noise, easy starting, etc. In addition, there are measures to prevent oil return and measures to prevent oil seal leakage from contaminating the site.
The pump is the basic equipment for obtaining vacuum. It can be used alone or as a backing pump and pre-pump for various high vacuum systems.
The air inlet of the pump must be continuously opened to the atmosphere for no more than three minutes.
The pump is not suitable for pumping out gases containing particulate dust that are corrosive to metals, chemically react with the pump oil, and explosive gases that contain too much oxygen.
The pump shall not be used as a compression pump or transfer pump.
The pump is allowed to operate continuously for a long time under the condition that the working environment temperature of the pump is within the range of ℃ and ℃, the relative temperature is not greater than 100°C, and the air inlet pressure is less than 10°C.
When installing the power supply, follow the instructions on the motor nameplate and pay attention to the fact that the direction of rotation of the motor is consistent with the direction of the arrow on the support.
The diameter of the pipe of the continuously pumped container should be no less than the diameter of the air inlet of the pump, and the pipe should be short and have few elbows. At the same time, pay attention to the leakage of the pipe.
Check the oil level before starting each time. It is advisable to inject oil to the diameter/height of the oil gauge glass when the pump is stopped.
The pump oil is clean grade vacuum pump oil.
The pump can be started at once under atmospheric pressure or any vacuum. If it is difficult to start a single-stage pump, you can start it by removing the plug cap of the air inlet pipe and then put it into operation.
