Abstract
The utility model discloses a reciprocating vacuum pump. The reciprocating vacuum pump comprises a body, wherein a cylinder is arranged in the body; an air inlet is formed in the top of the cylinder; an air outlet is formed in the bottom of the cylinder; a double-piston and a piston rod are arranged in the cylinder; the double-piston is fixed to one end of the piston rod, and the other end of the piston rod is connected with a piston connecting rod; the piston connecting rod is connected with the circumference of a crankshaft in a sliding manner; a maintenance box is arranged at the joint of the piston rod and the piston connecting rod; reciprocating components are arranged in the maintenance box. As the maintenance box is arranged at the joint of the piston rod and the piston connecting rod, the maintenance is facilitated, the reciprocating power comes from the reciprocating components, and a spring is convenient to replace.
Description
Technical field
The utility model relates to a kind of vacuum pump, relates in particular to a kind of reciprocating vacuum pump.
Background technique
Reciprocating vacuum pump (claiming again piston type vacuum pump) is dry vacuum pump, and it is to rely on piston reciprocates in cylinder to suck with Exhaust Gas.Reciprocal power, if pure machine power for example realizes by pull bar, after long-time use, easily goes wrong.Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Model utility content
For addressing the above problem, the utility model provides a kind of lubricated reliable reciprocating vacuum pump.
The technical solution adopted in the utility model is:
