Preferably, being equipped with inflatable chamber between each oil removal chamber and body, inflatable chamber communicates with oil removal chamber, body respectively, fills
Air cavity is provided with inert gas import, inert gas outlet, by being filled with noble gas in inflatable chamber, it is possible to plays protection and makees
With.
Preferably, described bent axle is linked with driving means by pulley transmission mechanism, passes through pulley transmission mechanism
Can stop because of the phenomenon of the excessive motor damage of starting current.
The present invention is compared with prior art had the beneficial effect that
The present invention is improved by existing WLW type vacuum pump, smart structural design, and two WLW type vacuum pumps share one
Body, has the advantage that floor space is little；Two WLW type vacuum pumps share a bent axle, when bent axle rotates a circle, whole back and forth
Formula vacuum pump is capable of 2 intake and exhaust circulation, makes rate of air sucked in required add one times, while ensureing rate of air sucked in required and vacuum,
Decrease the operating power of equipment, save production cost；The cylinder splitting of two WLW type vacuum pumps is installed, and therefore remains former
The advantage such as have QI KOU direction flexibly, all consumable accessorys of reciprocating vacuum pump the most of the present invention all lead to WLW type vacuum pump
With, easy to maintenance, maintenance cost is low.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
As shown in Figure 1, 2, reciprocating vacuum pump of the present invention includes air inlet pipe 13, exhaustor 18 and shares one
Body 1, the two WLW type vacuum pumps (respectively WLW type vacuum pump one 7 and WLW type vacuum pump 2 16) of cylinder 11 partial installation, two
The toggle of WLW type vacuum pump shares a bent axle 2, and bent axle 2 is by pulley transmission mechanism 15 and driving means 19
Linkage, bent axle 2 is provided with upper and lower two eccentrically mounted ends 3, and the connecting rod 4 of two toggles is pacified by connecting rod bearing shell respectively
It is contained on the eccentrically mounted end of above-mentioned two 3；The cylinder 11 of WLW type vacuum pump 1 is provided with air inlet 1, air vent 1,
The cylinder 11 of WLW type vacuum pump 2 16 is provided with air inlet 2 14, air vent 2 17, and air inlet 1, air inlet 2 14 connect same
A piece air inlet pipe 13, air vent 1, air vent 2 17 connect same exhaustor 18；Corresponding each cylinder 11 arranges an oil removal
Chamber 9, each oil removal chamber 9 is between its corresponding cylinder block 12 and body 1, and the length in oil removal chamber 9 is more than a piston
10 strokes, it is ensured that in body 1, lubricating oil will not leak into cylinder 11；It is equipped with inflatable chamber 6 between each oil removal chamber 9 and body 1, fills
Air cavity 6 communicates with oil removal chamber 9, body 1 respectively, and inflatable chamber 6 is provided with inert gas import, inert gas outlet, by filling
Air cavity 6 is filled with noble gas, it is possible to play a protective role.In the present embodiment, two WLW type vacuum pumps all use WLW-600 true
Empty pump, current WLW-600 vacuum pump is the WLW type vacuum pump that rate of air sucked in required is maximum, therefore, uses two WLW-600 vacuum pump energy
Rate of air sucked in required is enough made to reach 1200L/s, to meet the demand of big rate of air sucked in required technique.
The work process of above-mentioned reciprocating vacuum pump is as follows: starting driving means 19 (using motor), belt pulley passes
Motivation structure 15 band dynamic crankshaft 2 rotates, in rotation process, on bent axle 2, once two eccentrically mounted ends 3 drive respectively
Two connecting rods 4 are reciprocating, owing to, in tradition WLW type vacuum pump, the other end of connecting rod 4 is joined with piston rod 5 by crosshead
Closing and install, piston rod 5 connects piston 10, i.e. bent axle 2, connecting rod 4, crosshead, piston rod 5, piston 10 and is installed as integrally, therefore,
Piston 10 can be driven to move reciprocatingly in cylinder 11 by connecting rod 4, reach suction and discharge effect, so rotate one when bent axle 2
Zhou Shi, two WLW type vacuum pumps each complete 1 intake and exhaust circulation, make rate of air sucked in required add one times.
The present invention is improved by original WLW type vacuum pump, because two WLW type vacuum pumps share a bent axle 2, cylinder 11
Partial installation, and install on two eccentrically mounted ends 3 one of two toggle connecting rods 4, be once located on bent axle 2, so,
On the one hand ensure that axiality when cylinder 11 is installed, on the other hand, wherein while a WLW type vacuum pump air-breathing another
WLW type vacuum pump discharges, when bent axle 2 rotates a circle, it is possible to realize 2 intake and exhaust circulation, is ensureing rate of air sucked in required and vacuum
While, decrease the operating power of equipment, save production cost.Owing to two WLW type vacuum pumps share a body 1, because of
This floor space is little, enables the invention to be applicable to the working region of narrow space, also overcomes simplex pump simultaneously and shakes big, dimension
Repair the defects such as inconvenience.Except above-mentioned points, due to cylinder 11 partial installation, the therefore inlet and outlet mouth still position of two WLW type vacuum pumps
On corresponding cylinder 11, it is possible to the advantage retaining original WLW type vacuum pump, the institute of reciprocating vacuum pump the most of the present invention
There is consumable accessory all general with WLW type vacuum pump, the most easy to maintenance, maintenance cost is low.
