Abstract
The utility model discloses a composite cleaning vacuum pump, including a pump shell, an automatic reversing valve, a roots vacuum pump, a rotary vane vacuum pump and an oil-air-separated device. The pump is characterized in that: the roots vacuum pump and the rotary vane vacuum pump are arranged in the pump shell; the roots vacuum pump is connected with the rotary vane vacuum pump through pipes; an absorption room which obtains clean air is arranged at the upper part of the rotary vane vacuum pump. Under the closed-loop control of the automatic reversing valve, the utility model with an absorption room has a compound structure of the roots vacuum pump and the rotary vacuum pump. The utility model has the advantages that the pump can maintain high pumping speed and high efficiency and has compact structure, low power consumption and low cost in the atmosphere high up to 0.13 Pago.
Description
Technical field
The utility model relates to the pump technical field, particularly a kind of combined type clean vacuum pump.
Background technique
The oil seal type oil-sealed rotary pump is at present at coating technique, metallurgical technology, still obtain general application in the industrial departments such as electronic technology, their common feature is to rely on the glossy and sealing of pump, in use, to have a spot of pump oil in the senior chamber of pump is thrown into by in the system of taking out, oil in the senior chamber also can " be creeped " to the quilt system of taking out at leisure simultaneously, these processes enter by the pump oil in the system of taking out, volatilization constantly under low pressure, although some oily vapours is taken away by pump itself, but still have some oily vapourss to backflow in the system, can influence the quality of finished product, quantity, safety and maintenance.This shows the industrial vacuum pump that just needs a kind of cleaning, some oil-free vacuum pumps had appearred in recent years, as pawl formula pump, screw pump, vortex pump etc., though they can realize not having the clean vacuum of oil, that but a series of ten minutes distinct issues are compression ratios is not high, pumping speed is little, complex structure, make and the maintenance cost height, cost an arm and a leg.
Summary of the invention
The purpose of this utility model provides a kind of combined type clean vacuum pump that can obtain clean vacuum and big pumping speed.
The utility model is to realize like this, it comprises pump case, Roots pump, sliding vane rotary vacuum pump and deaerator, it is characterized in that in pump case, being equipped with Roots pump and sliding vane rotary vacuum pump, connect by pipeline between Roots pump and the sliding vane rotary vacuum pump, the adsorption chamber that obtains clean vacuum is housed above the sliding vane rotary vacuum pump suction port, and the place is provided with automatic diverter valve at the Roots pump suction port.
The utility model is owing to be provided with the absorption chamber and adopted Roots pump and the sliding vane rotary vacuum pump composite structure, and closed loop control by automatic diverter valve, can in the wide-range of barometric pressure to 0.13 handkerchief, keep big pumping speed, high efficiency, have compact structure, power consumpiton is low and cost is little advantage.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is a combined type clean vacuum pump structure schematic representation
Fig. 2 is the pumping process process schematic representation of combined type clean vacuum pump,
Embodiment
As Fig. 1---shown in 2, this combined type clean vacuum pump comprises pump case 11, automatic diverter valve 1, Roots pump 2, sliding vane rotary vacuum pump 4 and gas piping 7,8,9,10,12 and deaerator 13, Roots pump 2 and sliding vane rotary vacuum pump 4 are installed in pump case 11, connect by pipeline between Roots pump 2 and the sliding vane rotary vacuum pump 4, the adsorption chamber 3 that obtains clean vacuum is housed above sliding vane rotary vacuum pump 4 suction ports 6,2 suction port places are provided with automatic diverter valve 1 at Roots pump, and Roots pump of installing in housing and sliding vane rotary vacuum pump can be realized string, parallel-connection structure.Its pumping process is, when the initial conditions of suction port is barometric pressure, the gas flow process is represented with two-wire, pumped gas enters automatic diverter valve 1 through suction port 5, the spool of automatic diverter valve 1 is moved to left, back gas is through pipeline 7,8,9 enter absorption chamber 3, coercibility steam in the pumped gas is become trapped in the absorption chamber 3, remaining dry gas enters in the sliding vane rotary vacuum pump 4 through pipeline 10, and discharge by the outlet valve of sliding vane rotary vacuum pump 4, after the gas and oil separating plant of the pump housing filters, outside the excavationg pump, when suction port 6 force value reached a certain setting value, automatic diverter valve 1 was connected pipeline 12, and pumped gas by the road 7 afterwards---Roots pump 2,---absorption chamber 3 is---after pipeline 10---sliding vane rotary vacuum pump 4---deaerator 13 filters pipeline 9 outside the excavationg pump.
