Therefore it is easy to maintenance, maintenance cost is low.
Preferably, the two WLW type vacuum pumps are all made of WLW-600 vacuum pump.WLW-600 vacuum pump is pumping at present
Maximum WLW type vacuum pump is measured, therefore, sucking rate can be made to reach 1200L/s using two WLW-600 vacuum pumps, to meet
The demand of big sucking rate technique.
Preferably, an oil removal chamber is arranged in corresponding each cylinder, and each oil removal chamber is located at cylinder block and machine corresponding to it
Between body, the length of oil removal chamber is greater than a piston stroke, it is ensured that lubricating oil will not leak into cylinder in body.
Preferably, inflatable chamber is equipped between each oil removal chamber and body, inflatable chamber is communicated with oil removal chamber, body respectively, filled
Air cavity is equipped with inert gas import, inert gas outlet, by being filled with inert gas in inflatable chamber, can play protection and make
With.
Preferably, the crankshaft is linked by pulley transmission mechanism and driving device, passes through pulley transmission mechanism
It can prevent because of starting current excessive the phenomenon that burning motor.
Compared with the prior art, the invention has the beneficial effects that:
The present invention is improved by existing WLW type vacuum pump, smart structural design, and two WLW type vacuum pumps share one
Body, with the small advantage of occupied area；Two WLW type vacuum pumps share a crankshaft, entire reciprocal when crankshaft rotates a circle
Formula vacuum pump can be realized 2 intake and exhaust circulation, and sucking rate is made to increase one times, while guaranteeing sucking rate and vacuum degree,
The operating power for reducing equipment, saves production cost；The cylinder splitting of two WLW type vacuum pumps is installed, therefore remains original
Have the advantages that port direction is flexible, while all vulnerable parts of reciprocating vacuum pump of the present invention are all logical with WLW type vacuum pump
With easy to maintenance, maintenance cost is low.

Specific embodiment
The embodiment of the present invention is described further with reference to the accompanying drawing:
As shown in Figure 1, 2, reciprocating vacuum pump of the present invention include air inlet pipe 13, exhaust pipe 18 and share one
Body 1,11 partial installation of cylinder two WLW type vacuum pumps (respectively WLW type vacuum pump 1 and WLW type vacuum pump 2 16), two
The crank link mechanism of WLW type vacuum pump shares a crankshaft 2, and crankshaft 2 passes through pulley transmission mechanism 15 and driving device 19
Linkage, crankshaft 2 are equipped with upper and lower two eccentrically mounted ends 3, and the connecting rod 4 of two crank link mechanisms is pacified by connecting rod bearing shell respectively
On above-mentioned two eccentrically mounted end 3；The cylinder 11 of WLW type vacuum pump 1 is equipped with air inlet 1, exhaust outlet 1,
The cylinder 11 of WLW type vacuum pump 2 16 is equipped with air inlet 2 14, exhaust outlet 2 17, and air inlet 1, the connection of air inlet 2 14 are same
A piece air inlet pipe 13, exhaust outlet 1, exhaust outlet 2 17 connect same root exhaust pipe 18；An oil removal is arranged in corresponding each cylinder 11
Chamber 9, each oil removal chamber 9 are located between the cylinder block 12 and body 1 corresponding to it, and the length of oil removal chamber 9 is greater than a piston
10 strokes, it is ensured that lubricating oil will not leak into cylinder 11 in body 1；It is equipped with inflatable chamber 6 between each oil removal chamber 9 and body 1, is filled
Air cavity 6 is communicated with oil removal chamber 9, body 1 respectively, and inflatable chamber 6 is equipped with inert gas import, inert gas outlet, by filling
It is filled with inert gas in air cavity 6, can be played a protective role.In the present embodiment, it is true that two WLW type vacuum pumps are all made of WLW-600
Sky pump, WLW-600 vacuum pump is the maximum WLW type vacuum pump of sucking rate at present, therefore, using two WLW-600 vacuum pump energy
Enough sucking rate is made to reach 1200L/s, to meet the needs of big sucking rate technique.
The course of work of above-mentioned reciprocating vacuum pump is as follows: starting driving device 19 (uses motor), and belt pulley passes
Motivation structure 15 with dynamic crankshaft 2 rotate, during rotation, on crankshaft 2 one on, once two eccentrically mounted ends 3 drive respectively
Two connecting rods 4 are reciprocating, since in traditional WLW type vacuum pump, the other end of connecting rod 4 is matched by crosshead with piston rod 5
Installation is closed, piston rod 5 connects piston 10, i.e. crankshaft 2, connecting rod 4, crosshead, piston rod 5, the installation of piston 10 is integrated, therefore,
Piston 10 is able to drive in cylinder 11 by connecting rod 4 to move reciprocatingly, reaches suction and discharge effect, in this way when crankshaft 2 rotates one
Zhou Shi, two WLW type vacuum pumps respectively complete 1 intake and exhaust circulation, sucking rate are made to increase one times.
The present invention is improved by original WLW type vacuum pump, because two WLW type vacuum pumps share a crankshaft 2, cylinder 11
Partial installation, and install two crank link mechanism connecting rods 4 two eccentrically mounted ends 3 one on, be once located on crankshaft 2, in this way,
On the one hand it can guarantee concentricity when cylinder 11 is installed, it is on the other hand, another while a WLW type vacuum pump air-breathing wherein
WLW type vacuum pump discharges can be realized 2 intake and exhaust circulation when crankshaft 2 rotates a circle, and guarantee sucking rate and vacuum degree
While, reduce the operating power of equipment, saves production cost.Since two WLW type vacuum pumps share a body 1, because
This occupied area is small, enables the invention to the working region suitable for narrow space, while also overcoming simplex pump and shaking big, dimension
The defects of repairing inconvenience.Except above-mentioned points, due to 11 partial installation of cylinder, the inlet and outlet mouth of two WLW type vacuum pumps still position
In can retain original WLW type vacuum pump on corresponding cylinder 11 the advantages of, while the institute of reciprocating vacuum pump of the present invention
Have vulnerable part all with WLW type vacuum pump it is general therefore easy to maintenance, maintenance cost is low.
