Description
Technical field
The utility model relates to the vehicular oil air separation, and specifically a kind of exhaust hydrant cart thorough, that improve oil-gas separation efficiency and reduction use cost vacuumizes gas and oil separating plant.
Background technology
The typical, filtered separator of prior art mainly is comprised of housing, separation filter core, Coalescence filter core, crosspointer differential manometer, automatic blow off valve valve air relief, Manual air-release valves, automatic drain valve and Manual water drain valve etc.
Separating filter core is the second level water-oil separating element in separator, and on the stainless steel steel wire that is 100 orders/in with mesh, the strong polytetrafluoroethylene (PTFE) of spraying repellency is made.It is fixed on the cruciform joint of outlet lower end by center bolt.
Coalescence filter core is first order water-oil separating element, is also the main element of water-oil separating.By diameter, the hydrophilic fibers layer different with density forms for it.Its inner frame is the cylinder that aluminium expanded sheets is made; The outer outer casing play of filter course is that the rustproof aluminium sheet with punching rolls and forms.It is fixed on the dividing plate in the entrance point shell cover with screw rod and support thereof.
Gs-oil separator is set directly at the case top of above-mentioned filter separator, specifically by the automatic blow off valve valve air relief upside-down mounting under the top cover of top gas receiver, while in housing, gas being arranged, gas is assembled at the gas receiver top, its pasta is descended, force stainless steel ball to descend, and the decline of the valve disc on drivening rod, vent valve automatically opened.After gas is emitted, in gas receiver, pasta rises, and forces stainless steel ball to rise, and the rising of the valve disc on drivening rod, leans on the buoyancy of ball float to make valve disc and seal washer sealing, and vent valve cuts out automatically.Manual air-release valves also is housed on the gas receiver top cover.Manual air-release valves must be at first opened during work, just the automatic blow off valve valve air relief automatic deflation can be made.In pipeline, gas separates when complete, automatically blocks pipeline.
In the pump oil pipe line, the filter separator with gs-oil separator of prior art is mounted on the vacuum-pumping pipeline between auxiliary oil pump and main oil pump, by gs-oil separator, realizes the gas in main oil pump is pumped.Auxiliary oil pump exports with main oil pump that the vacuum-pumping pipeline bore be connected is less, length is shorter, in vacuum, fluid flow velocity in this pipeline is very fast, as blocked too early vacuum-pumping pipeline, in main oil pump, also there is too much gas, can't drop into normal operation, otherwise as can not block in time vacuum-pumping pipeline, fluid will enter gas extraction system through auxiliary oil pump, thus, and the work that will inevitably bring a large amount of corresponding oil-collectings and reclaim oil plant.During above-mentioned gs-oil separator work, when the interface of oil and gas rises while ball float being floated close main valve, may exist and enter gs-oil separator because of a large amount of gas mixtures, make the very fuzzy situation of the interface of oil and gas in gs-oil separator, so, the induction of the Direct Action Type of ball float may exist mistake to block the path of bleeding, or frequently fluctuates and cause the wild effect of bleeding; The support staff directly opens and closes Manual air-release valves according to practical experience, can't complete effectively accurately and timely and vacuumize operation, causes the problems referred to above, makes the work workman input cost of a large amount of corresponding oil-collectings and recovery oil plant higher, and use cost is just higher.
In sum, the gs-oil separator exhaust of prior art is not thoroughly, oil-gas separation efficiency is low and use cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of exhaust hydrant cart thorough, that improve oil-gas separation efficiency and reduction use cost and vacuumizes gas and oil separating plant.
For realizing that the technical scheme that the utility model above-mentioned purpose adopts is: a kind of hydrant cart vacuumizes gas and oil separating plant, comprise housing, be arranged on housing bottom for vacuum-pumping pipeline on the oil gas admission passage connected of main oil pump, be arranged on case top for vacuum-pumping pipeline on the exhaust passage connected of auxiliary oil pump, described oil gas admission passage and exhaust passage all are communicated with the inner chamber of housing, in the inner chamber of housing, are provided with ball float; It is characterized in that: the top of described ball float is fixed with air bleeding valve, and this air bleeding valve comprises again main valve and pilot valve;
