Abstract
The invention relates to an oil filter base for a lubricating oil system of a compressor, which comprises an oil filter base body, wherein an oil filter inlet, an oil filter outlet and an oil filter joint are arranged on the oil filter base body, a bypass safety valve spool is arranged in the oil filter base body, a limiting sleeve is arranged at the front end of the bypass safety valve spool, a bypass safety valve spring seat is connected at the rear end of the bypass safety valve spool, a bypass safety valve spring is sleeved on the bypass safety valve spring seat, a bypass safety valve retainer ring is arranged between the limiting sleeve and the bypass safety valve spool, snap springs are arranged between the bypass safety valve spring seat and the bypass safety valve spool, and the snap springs are positioned in clamping grooves of the bypass safety valve spool. The invention has the advantages of reasonable structure, firm performance, small pressure loss, and particularly, oil filter blockage, and opening of the oil filter seat with the differential pressure safety valve through the differential pressure safety valve when the oil supply pressure is insufficient, thereby ensuring normal oil supply pressure and avoiding insufficient oil supply pressure.
Description
Technical field
The present invention relates to a kind of oily filter block, particularly a kind of oily filter block for compressor lubrication oil system.
Background technique
Oily filter block on current screw air compressor, one adopts electrical signal differential pressure switch, and carry out early warning oil filter blocking, another does not simply fill differential pressure switch, do not have oil filter blocking early warning.Front a kind of electrical signal differential pressure switch problem is easily to produce false alarm; everybody is made to create distrust to the early warning of electrical signal differential pressure switch; it also just loses original effect; normally run to screw machine and leave no small hidden danger; rear a kind of be thoroughly without any protection and prewarning information, if operating mode difference or client maintain not in time, oil leaches existing blocking; screw rod head because of oil starvation locking, will cause unnecessary loss.
Summary of the invention
The object of the invention is to overcome above deficiency, providing a kind of rational in infrastructure, robust performance, the oily filter block for compressor lubrication oil system that the pressure loss is little.
Object of the present invention is achieved through the following technical solutions: a kind of oily filter block for compressor lubrication oil system, comprise oily filter block body, described oily filter block body is provided with oil filter entrance, oil leaches mouth and oil filter joint, full by-pass relief valve spool is provided with in described oily filter block body, described full by-pass relief valve spool is positioned at oil filter ingress, stop collar is provided with in the front end of described full by-pass relief valve spool, full by-pass relief valve spring seat is connected with in the rear end of described full by-pass relief valve spool, on described full by-pass relief valve spring seat, cover has full by-pass relief valve spring, full by-pass relief valve back-up ring is provided with between described stop collar and full by-pass relief valve spring, between described stop collar and full by-pass relief valve spool, jump ring is equipped with between full by-pass relief valve spring seat and full by-pass relief valve spool, described jump ring is positioned at the draw-in groove of full by-pass relief valve spool,
Seal ring is provided with between described full by-pass relief valve spool and full by-pass relief valve spring.
The advantage that the present invention compared with prior art has is:
Rational in infrastructure, robust performance, the pressure loss is little, particularly occurs oil filter blocking, and when charge oil pressure is not enough, the oily filter block of band pressure reduction safety valve can opening by pressure reduction safety valve, ensures normal charge oil pressure, avoid because charge oil pressure is not enough.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is the A place enlarged view of Fig. 1;
Number in the figure: 1-oil filter block body, 2-oil filter entrance, 3-oil leach mouth, the filter of 4-oil joint, 5-full by-pass relief valve spool, 6-stop collar, 7-jump ring, 8-full by-pass relief valve spring seat, 9-full by-pass relief valve spring, 10-full by-pass relief valve back-up ring, 11-seal ring.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1, Fig. 2, Fig. 3 shows the embodiment of a kind of oily filter block for compressor lubrication oil system of the present invention: comprise oily filter block body 1, described oily filter block body 1 is provided with oil filter entrance 2, oil leaches mouth 3 and oil filter joint 4, full by-pass relief valve spool 5 is provided with in described oily filter block body 1, described full by-pass relief valve spool 5 is positioned at oil filter entrance 2 place, stop collar 6 is provided with in the front end of described full by-pass relief valve spool 5, full by-pass relief valve spring seat 8 is connected with in the rear end of described full by-pass relief valve spool 5, on described full by-pass relief valve spring seat 8, cover has full by-pass relief valve spring 9, full by-pass relief valve back-up ring 10 is provided with between described stop collar 6 and full by-pass relief valve spring 9, between described stop collar 6 and full by-pass relief valve spool 5, jump ring 7 is equipped with between full by-pass relief valve spring seat 8 and full by-pass relief valve spool 5, described jump ring 7 is positioned at the draw-in groove of full by-pass relief valve spool 5,
Seal ring 11 is provided with between described full by-pass relief valve spool 5 and full by-pass relief valve spring 9.
Lubricant oil enters oily filter block from import, after oil screen filters, leach mouth from oil enter compressor lubrication system, when oil screen blocking, when the pressure before oil screen exceedes full by-pass relief valve setting value, full by-pass relief valve is opened, thus avoids because front and back pressure reduction is excessive and damage oil screen.
When the present invention normally works, before and after oil filter, pressure reduction does not reach pressure reduction safety valve setting value, pressure reduction safety valve cuts out, and all lubricant oil enters backend terminal equipment lubrication, cooling after filtering filter via oil, when oil filter blocking, pressure reduction before and after oil filter increases, after reaching the setting value of pressure reduction safety valve, pressure reduction safety valve is opened, and lubricant oil can enter rear end equipment by pressure reduction safety valve, prevent due to oil filter blocking, rear end equipment can not get lubrication, cools and cause serious device security accident.
The present invention is rational in infrastructure, and the pressure loss is little, particularly occurs oil filter blocking, when charge oil pressure is not enough, the oily filter block of band pressure reduction safety valve can opening by pressure reduction safety valve, ensures normal charge oil pressure, avoid, because charge oil pressure is not enough, causing backend terminal equipment badly damaged.
