Description

V-type oilless reciprocating vacuum pump

Technical field

The utility model relates to the technical field of structures of vacuum pump.

Background technique

Existing vacuum pump fuselage slideway and fuselage are an integral body, and slideway is splash lubrication, and after the running, slideway may be pulled, and causes the maintenance expenses height; Existing vacuum pump bottom air inlet and exhaust valve is arranged in the Stuffing box inner chamber, is not easy to maintenance; Existing vacuum pump piston rod is connected with crosshead with extension bar, extension bar with piston, piston rod and locks unreliablely, easily becomes flexible after the long-term operation, causes phenomenons such as cylinder cap and piston damage.

The model utility content

The utility model purpose be to design a kind ofly take up an area of that the space is little, long service life, the V-type oilless reciprocating vacuum pump being convenient to safeguard.

The utility model comprises fuselage, a set of bell cranks mechanism, be connected two connecting rods on the crank mechanism, respectively with two two groups of crosshead slippers, two groups of slideways, two groups of piston assemblys, two cylinders, two cylinder caps that connecting rod is supporting, angle between described two connecting rod axis is an acute angle, two groups of detachable respectively being connected on the fuselage of slideway, described slideway is the spheroidal graphite cast iron slideway.

During running, under the driving of motor, the slidercrank mechanism that is made of bent axle, connecting rod, crosshead slipper and fuselage passes to piston with the linear reciprocating motion of crosshead slipper by piston rod, realizes suction gas process.Because the angle between two connecting rod axis of the present utility model is an acute angle, the V-shape structure of formation, mutually perpendicular arrangement can reduce floor space of the present utility model greatly between two more existing connecting rod axis.In addition, because the utility model adopts the spheroidal graphite cast iron slideway, and split type spheroidal graphite cast iron slideway and fuselage ways of connecting, not only intensity improves, and directly increases the service life, and maintains easily, and reduces operating cost.

The utility model is provided with air inlet and exhaust valve on the top of cylinder head, and air inlet and exhaust valve down is set on the circumferential surface of cylinder, has also made things convenient for maintenance and detection.

The slideway sidewall is offered oil inlet hole, and described oil inlet hole is connected with external oil feed pump.Adopt this pressure lubrication mode, lubricant oil has guaranteed the sufficient lubrication of slideway by shaft head gear oil pump and external motor oil pump fuel feeding behind oil separator, has reduced the wearing and tearing of slideway and crosshead, has prolonged working life.

Piston rod adds the end that seam is connected crosshead slipper by screw thread.Guaranteed the Location accuracy of piston rod.

In addition, also be provided with direct selling between piston rod and the crosshead slipper, can further guarantee between piston rod and the crosshead slipper not loosening after the long-term operation.

Connect upper and lower cover plate respectively in the piston rod end that is connected with piston, be connected by bolt between upper and lower cover plate and the piston.Because piston rod and piston adopt upper and lower cover plate to add the Placement of bolt, guarantee between piston rod and the piston be connected after the long-term operation loosening.

On fuselage, divide to add the inlet and outlet air flue is set.Can reduce the height of porting, and when maintenance Stuffing box, cylinder, cylinder head, not need to dismantle airduct, reduce repair density, reduce maintenance load.

Bottom at fuselage is provided with water storage cavity.Can feed cooling water summer, reduces the temperature of lubricant oil; Can feed hot water or water vapour winter, improves the temperature of lubricant oil, avoids the freezing of lubricant oil (this mode of heating is compared with the external electric heater, reliable, safety, economy), thereby guarantee the running reliably and with long-term of equipment.
