Abstract
The utility model provides a reciprocating vacuum pump, which comprises a valve plate, an air cylinder, a crankshaft, connecting rods, a piston, a piston ring and a crankshaft box, wherein the valve plate is arranged above the air cylinder, the piston and the piston ring are arranged in the air cylinder, the piston is fixedly connected with the crankshaft via the connecting rod, and the crankshaft is arranged in the crankshaft box. The utility model is characterized in that the crankshaft is symmetrically distributed with four connecting rods which are vertical to horizontal direction, and four air cylinders which are corresponding to the connecting rods and the piston are arranged on the same plane. In the condition of not change the functional requirements of existing reciprocating vacuum pumps, the utility model has the advantages of small volume, energy saving, low noise, and low environmental pollution.
Description
The utility model provides a kind of reciprocating vacuum pump, belongs to the vacuum pump technology field.
Existing reciprocating vacuum pump mostly is single cylinder, and volume is big, and balance quality is not good enough, and vibration is big, noise height, big energy-consuming.
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, volume is little, noise is low, the reciprocating vacuum pump of energy saving.
The purpose of this utility model is achieved in that
Comprise valve plate, cylinder, crank, connecting rod, piston, piston ring and crank box, wherein valve plate is positioned on the cylinder, be provided with piston and piston ring in the cylinder, piston is fixedlyed connected with crank through connecting rod, crank is positioned at crank box, it is characterized in that: perpendicular to the substantially horizontal symmetric arrangement 4 connecting rods are arranged on the crank, be positioned at same plane with connecting rod, 4 cylinders that piston is corresponding.
Its working principle is: driven the belt pulley rotation that is fixed on the crank by prime mover, by connecting rod rotatablely moving of prime mover become piston, the straight reciprocating motion of piston ring in cylinder that is fixed on the connecting rod the other end again, it is inhaled, the purpose of exhaust thereby reach.Be to strengthen balance, be arranged on 4 connecting rods on the crank perpendicular to the substantially horizontal symmetric arrangement, 4 pistons that connecting rod promoted are done the to-and-fro motion of vertical-horizontal direction in same plane.
The utility model compared with prior art has following advantage:
1, adopts multi-cylinder, reduced small product size;
2,4 pistons are done in same plane in the to-and-fro motion of vertical-horizontal direction, have made full use of the weight of piston self, have saved the energy;
3, removed non-equilibrium factor, balance quality is good, vibrates for a short time, and noise is low, has reduced the pollution to environment.
Fig. 1 is the utility model embodiment's a structural representation;
Below in conjunction with accompanying drawing the utility model is described further:
1-crank box 2-rear bearing gland 3-adjustment disk 4-crank 5-rear bearing 6-cylinder 7-connecting rod 8-piston 9-cylinder head 10-suction port 11-relief opening 12-valve plate 13-piston ring 14-fore bearing gland 15-fore bearing
Crank 4 is positioned at crank box 1, its front end suit is fixed with fore bearing 15 and fore bearing gland 14, be connected with electric-motor-driving by the belt pulley drive, its rear end suit rear bearing 5, and it is fixing by adjustment disk 3 and rear bearing gland 2, perpendicular to the substantially horizontal symmetric arrangement 4 connecting rods 7 are arranged on the crank 4, piston 8 in the cylinder 6 is fixedlyed connected with crank 4 through connecting rod 7, piston 8 is provided with piston ring 13, valve plate 12 is positioned on the cylinder 6, and fixedly connected with cylinder head 9, cylinder head 9 is provided with suction port 10 and air outlet 11.
