Abstract
The utility model discloses a vertical oilless vacuum pump. The vertical oilless vacuum pump comprises a base and a machine body, wherein a cylinder is arranged in the machine body; a piston and a piston rod are arranged in the cylinder; the lower end of the piston rod is connected with a piston connecting rod; the bottom of the piston connecting rod is inserted into a crosshead; the crosshead is connected with an upper end hole of a connecting rod; a lower end hole of the connecting rod is connected with the circumference of a crankshaft in a sliding manner; an auxiliary pneumatic component is arranged on the piston rod below the piston; a telescopic component is arranged at the joint of the lower end of the piston rod and the piston connecting rod. Once the piston is corroded to some extent, the auxiliary pneumatic component comes into play to enable the cylinder to still work; the telescopic component enables the lower end of the piston rod to be arranged within a certain distance in the piston connecting rod, the length of the distance is controllable, and once the distance is too long, an alarming contact alarms; the vertical oilless vacuum pump is wide in adaptability.
Description
Technical field
The utility model relates to a kind of vacuum pump, relates in particular to a kind of without oily vertical type vacuum pump.
Background technique
In known vacuum pump, the vacuum pump that particularly large discharge capacity vacuumizes, the piston type vacuum pump of crank-connecting rod transmission is widely adopted, and the one-sided wearing and tearing of horizontal type structure are severe, and the rising structure progressively with plurality of advantages such as stressed even wearings replaces.Disclosed without oily vertical type vacuum pump-201210413315.X, its piston moves up and down in chamber, easily wearing and tearing, and in addition, the distance that piston rod moves up and down is constant, adaptive surface is narrow.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, it is a kind of lubricated reliably without oily vertical type vacuum pump that the utility model provides.
The technical solution adopted in the utility model is:
Without oily vertical type vacuum pump, comprise base and fuselage, in described fuselage, there is cylinder, in described cylinder, be provided with piston and piston rod, described piston-rod lower end is connected with piston rod, and insert in crosshead described piston rod bottom, described crosshead is connected with the upper end hole of connecting rod, the lower stomidium of described connecting rod is connected with bent axle circumferential slippage, and the piston rod of described piston below is provided with auxiliary Pneumatic assembly, and described piston-rod lower end and piston rod joint are provided with telescopic component.
Described auxiliary Pneumatic assembly comprises tilt stand and be located at the block rubber on tilt stand, and described tilt stand is distributed in piston rod surrounding, and described block rubber is close to cylinder wall.
Described telescopic component comprises is located at the joint of piston-rod lower end and the spring around joint surrounding, upright to Alarm contactor under described joint.
The shell in described small end hole has tank filler sleeve outward.
The beneficial effects of the utility model: auxiliary Pneumatic assembly is in the situation that piston weares and teares to some extent, play a role, cylinder can also be worked, telescopic component makes piston-rod lower end be located at a segment distance in piston rod, this can control apart from length, the oversize Alarm contactor of distance is just reported to the police, wide adaptability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, base, 2, fuselage, 3, cylinder, 4, piston, 5, piston rod, 6, piston rod, 7, crosshead, 8, connecting rod, 9, bent axle, 10, tilt stand, 11, block rubber, 12, joint, 13, spring, 14, Alarm contactor, 15, tank filler sleeve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, of the present utility model without oily vertical type vacuum pump, comprise base 1 and fuselage 2, in fuselage 2, there is cylinder 3, in cylinder 3, be provided with piston 4 and piston rod 5, piston rod 5 lower ends are connected with piston rod 6, insert in crosshead 7 piston rod 6 bottoms, and crosshead 7 is connected with the upper end hole of connecting rod 8, and the lower stomidium of connecting rod 8 is connected with bent axle 9 circumferential slippage, the piston rod 5 of piston 4 belows is provided with auxiliary Pneumatic assembly, and piston-rod lower end and piston rod joint are provided with telescopic component.
Auxiliary Pneumatic assembly comprises tilt stand 10 and is located at the block rubber 11 on tilt stand 10, and tilt stand 10 is distributed in piston rod 5 surroundings, and block rubber 11 is close to cylinder 3 walls.Owing to working long hours, piston weares and teares to some extent, cannot normally work, and auxiliary Pneumatic assembly replaces piston to proceed work.
Telescopic component comprises is located at the joint 12 of piston rod 5 lower ends and the spring 13 around joint 12 surroundings, and 12 times Founders of joint are to Alarm contactor 14.Piston-rod lower end stretches in piston rod, and distance is longer, has spring to play buffer function when backhaul, and in the time that distance is excessive, Alarm contactor can be reported to the police, safe and reliable.
The shell of connecting rod 8 upper end holes has tank filler sleeve 15 outward.Easy to lubricate, lubricated inner member.
Auxiliary Pneumatic assembly, in the situation that piston weares and teares to some extent, plays a role, and cylinder can also be worked, and telescopic component makes piston-rod lower end be located at a segment distance in piston rod, and this can control apart from length, and the oversize Alarm contactor of distance is just reported to the police, wide adaptability.
