Abstract
The utility model relates to a vacuum pump which is characterized in that a machine oil chamber is arranged on a pump body; an outlet is arranged on the machine oil chamber; the machine oil chamber and an inner cavity of the pump body are communicated through an oil inlet in a back cover; an oil (gas) outlet on the pump body is communicated with an oil (gas) outlet pipe in the machine oil chamber; one side of the oil (gas) outlet pipe is provided with an oil baffle plate. The utility model overcomes the phenomenon that an oil pipe of a common pipeline connecting type vacuum pump is easy to age and damage or the oil is leaked caused by an unreliable joint, and thus an engine is burned. The utility model has the advantages of simple structure, independent circulation and convenient maintenance.
Description
The utility model relates to a kind of vacuum pump.
Existing vacuum pump all is made up of the pump housing, rotor, blade, one-way valve, oil-feed screw, give vent to anger (oil) joint and screw etc., when pump work, machine oil from the diesel-engine body main oil gallery enters vacuum pump by advancing by pipe and oil-feed screw after throttling, lubricated each moving element seals simultaneously.Last air mixing of coming with suction together enters gear chamber cover through steam outlet pipe and gets back to crankcase.The oil inlet pipe of this vacuum pump and give vent to anger that (oil) pipe place is often aging because of oil pipe, breakage or joint are insecure etc. causes leakage of oil, in case this situation occurs, just can be in minutes to the greatest extent the oil leak of whole system, and the driver is difficult for finding, cause engine bearing to burn out, even motor seriously damages, and causes enormous economic loss.Simultaneously, this vacuum pump maintenance also not easy to assemble.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby provides a kind of simple in structure, vacuum pump that can the independent loops fuel feeding.
The utility model comprises the forward and backward lid rotor of the pump housing, blade and eccentric bushing, rotor passes through the eccentric bushing eccentric in the pump housing, the blade that embeds in the rotor is close to pump housing inwall, the pump housing is sealed by forward and backward lid, bonnet is provided with a machine oil chamber, and the machine oil chamber is provided with the air outlet, is communicated with by the filler opening in the bonnet between machine oil chamber and pump housing inner chamber, also be provided with fuel-displaced (gas) mouthful and machine oil indoor fuel-displaced (gas) on the pump housing and manage and be communicated with, a side of fuel-displaced (gas) pipe is provided with oil baffle.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
As shown in the figure, the utility model comprises the pump housing 1, before, bonnet (2,3), rotor 4, blade 5 and eccentric bushing 6, rotor 4 passes through eccentric bushing 6 eccentrics in the pump housing 1, the blade 5 that embeds in the rotor 11 is close to the pump housing 1 inwall, the pump housing 1 is by preceding, bonnet (2,3) sealing, bonnet 3 is provided with a machine oil chamber 7, machine oil chamber 7 is provided with air outlet hole 13, be communicated with by the time hydraulic fluid port 8 in the bonnet 3 between machine oil chamber 7 and the pump housing 1 inner chamber, also be provided with fuel-displaced (gas) mouthfuls 9 on the pump housing 1 and be communicated with fuel-displaced (gas) pipe 10 in the machine oil chamber 7, fuel-displaced (gas) is managed a side of 10 oil baffle 12 is set.During use, machine oil utilizes in the vacuum pump body and the pressure difference of 7 of machine oil chambers enters vacuum pump from filler opening 8, lubricated each moving element, and seal, the air mixing of coming with suction is together discharged through fuel-displaced (gas) pipe 10 from fuel-displaced (gas) mouthfuls 9 then, machine oil keeps off go back to machine oil chamber 7 by oil baffle 12, and air 13 is discharged machine oil chambers 7 from the air outlet.Oil circulation running between the machine oil chamber and the pump housing has a circulatory system of one's own.
The utility model is by above-mentioned concrete setting, have simple in structure, implement easily advantage, can Avoid existing vavuum pump turnover pipeline leak, cause the System Computer oil leakage to the greatest extent, burn out sending out of engine accident Give birth to.
