Abstract

The invention discloses an improved vacuum pump, comprising a pump body. The improved vacuum pump is characterized in that the pump body is fixed on a machine base; a first-level rotor is arranged in the pump body; one end of the first-level rotor is connected with a motor arranged on one end of the pump body; the motor is also fixed on the machine base; one end of the first-level rotor, which is far away from the motor, is provided with a first-level top cover; the top of the first-level rotor is connected with the bottom of an oil transportation pipe penetrating through the first-level top cover; the top of the oil transportation pipe is arranged on the top of the pump body; the other end of the first-level rotor is connected with a second-level rotor; one end of the second-level rotor, which is far away from the motor, is provided with a second-level top cover; the outer side of the pump body, which is far away from the motor, is provided with an end cover matched with the pump body; the pump body is provided with an oil transportation end cover on the top position of the oil transportation pipe; the oil transportation end cover is provided with an end cover handle; and a buffer cushion is arranged between the pump body and the machine base. The improved vacuum pump has the advantages of simple structure, reliable and stable vacuum performance, convenience for rotor oil supply, low cost, high work efficiency and convenience for installation, disassembly and maintenance.

Description

technical field [0001] The invention relates to the field of pumps, in particular to an improved vacuum pump. Background technique [0002] The vacuum pump is a rotary variable displacement vacuum pump. It can be used in a wide pressure range with a backing pump. It has a large pumping speed and is insensitive to dust and water vapor in the pumped gas. Vacuum pumps are widely used in plastic machinery, pesticide chemical industry, dye chemical industry, brick and tile machinery, low temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, electronics industry, vacuum equipment, chemical fertilizer, metallurgy, petroleum, mining, foundation treatment and other fields . The vacuum pumps in the prior art have disadvantages such as complex structure, small and stable vacuum performance, low working efficiency, high cost, easy rusting of the rotor, resulting in non-operation, and inconvenient installation and ma...
