Abstract
The utility model relates to an improved air-cooled type roots vacuum pump, comprising a pump body. The improved air-cooled type roots vacuum pump is characterized in that an air intake is arranged at the top of the pump body; exhaust openings are arranged at the bottom and on the lateral walls of the pump body; a pair of rotors is arranged in the pump body; the rotors in pair are vertical with each other and are mutually engaged; and an overflowing valve is arranged in the pump body. The improved air-cooled type roots vacuum pump provided by the utility model has the advantages of simple structure, convenience for use, good energy-saving effect and simpleness in maintenance; and the air suction and the air exhaust can be completed by using the two 8-shaped rotors which synchronously rotate in the pump body.
Description
Technical field
The utility model relates to a kind of Roots pump, relates in particular to a kind of improved air-cooled Roots pump.
Background technique
Roots pump is a kind of rotary positive-displacement pump, and the Roots pump starting is fast, and driving power is little; Compact structure in recent years, has obtained using widely in fields such as metallurgy, petrochemical industry, papermaking, food and electron trades; And existing Roots pump effect for heat radiation is bad, has influenced the reliability of using, and power consumption is bigger in the course of the work; Safeguard more complicated, for addressing the above problem, the spy provides a kind of new technological scheme.
The model utility content
The purpose of the utility model provides a kind of improved air-cooled Roots pump.
The technological scheme that the utility model adopts is:
A kind of improved air-cooled Roots pump comprises the pump housing, and said pump housing top is provided with intakeport, and said pump housing bottom and sidewall are provided with relief opening, are provided with a pair of rotor in the said pump housing, and the vertical and engagement of said a pair of rotor also is provided with relief valve in the said pump housing.
Said rotor be shaped as the figure of eight.
Be provided with air filter in the said pump housing, said air filter is positioned at the intakeport place of the pump housing.
The utility model has the advantages that: simple in structure, easy to use, good energy-conserving effect is safeguarded simply, utilizes two figure of eight rotors in the pump housing, to do to rotate synchronously, thereby accomplishes air-breathing and exhaust.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model.
Wherein: 1, the pump housing, 2, intakeport, 3, relief opening, 4, rotor, 5, air filter, 6, relief valve.
