Abstract
It the utility model is related to petroleum and natural gas drilling technique field, a kind of more particularly to lubricating system inlet line structure suitable for lubricating system, it includes filter hood, filter, fuel sucking pipe, filter hood is vertically installed in the oil sump of lubricating system, it is sealedly and fixedly connected with lid on the oil sump of lubricating system, filter is built in filter hood and the top of filter and the top fixed seal connection of filter hood, fuel sucking pipe is fixedly connected with filter, the length of filter is more than the length of filter hood, filter places the height for reducing minimum inlet port vertically in the structure, so as to greatly reduce the probability that lubricating system inlet line suction side is emptied, and then reduce the noise of pump head, extend the service life of pump head, discharge pipe need to be only removed when maintenance or replacing filter, it is easy to operate simple.
Description
Technical field
Petroleum and natural gas drilling equipment technical field is the utility model is related to, it is more particularly to a kind of to be applied to lubricating system
Inlet line structure.
Background technology
The suction side of lubricating system, has been typically necessary filter by suction, as shown in figure 1, the suction of conventional lubrication system
End, using horizontal filter by suction 1 ', it is desirable to which oil mass must not there be filter by suction 1 ', due to filter by suction 1 ' size itself
The reason for, minimum oil level requires higher in system, slightly low on fuel, will be emptied, and produces loud noise and vibrations, formation are made an uproar
Sound pollutes, while also shortens the service life of pump head, because filter must be totally immersed into oil sump, is needing cleaning, more
Need to take apart the upper lid 3 ' of lubricating system when changing filter, it is also necessary to dismantling connection pipe 2 ', therefore maintainability is poor.
The utility model improves the structure of lubricating system inlet line, solves because low oil level is emptied, caused by oil
In be mixed into the problems such as bubble lubricant effect reduces, noise is big, pump head service life is short.
To solve the above problems, need to invent a kind of lubricating system inlet line structure, when being emptied for solving low oil level
Bubble lubricant effect is mixed into the oil of appearance reduces, the problems such as noise is big, pump head service life is short and maintainability is poor.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency in the presence of prior art, there is provided a kind of noise reduction simultaneously improves
The lubricating system inlet line structure of pump head service life.
In order to achieve the above object, the utility model provides following technical scheme.
A kind of lubricating system inlet line structure, it includes：
Filter hood, the filter hood are sealed and are fixedly connected with the upper lid of lubricating system, and the filter hood is vertical
It is placed in the lubricating system, the filter hood is fixedly connected and sealed with flange two, is suction below the filter hood
Hydraulic fluid port, the distance of the bottom of the filter hood and the lubricating system bottom determine according to pump head flow；
Fuel sucking pipe, the fuel sucking pipe are fixedly connected and sealed with flange one；
Filter, the filter are fixedly connected with the fuel sucking pipe, and the filter is built in the filter hood, institute
State filter and fuel sucking pipe junction encapsulation process.
As preferred scheme of the present utility model, the port of the fuel sucking pipe is connected with flange one, the flange one and institute
State flange two-way and cross bolt connection, the bottom of flange one and the joint face of flange two are machined with seal groove one, the seal groove
O-ring seal one is placed in one, filter is fixedly connected by bolt with flange one, and the bottom of flange one adds with filter joint face
Work, which has, places O-ring seal two in seal groove two.
As preferred scheme of the present utility model, the length of the filter hood is less than the length of the filter, described
Space between filter hood and the filter forms inlet port.
Compared with prior art, the beneficial effects of the utility model：
Filter places the height for reducing minimum inlet port vertically, is inhaled so as to greatly reduce lubricating system inlet line
Enter the probability that is emptied of end, and then reduce the noise of pump head, extend the service life of pump head, maintenance or when changing filter only
Discharge pipe need to be removed, it is convenient and simple.
Operation principle：
The top of the filter hood is tightly connected with the flange two, and lower section is as inlet port, when pump head is pumped, institute
State and negative pressure is formed in filter hood, under the pressure of peripheral atmospheric pressure, the oil in the lubricating system oil sump can be from the filtering
Enter the filter below device cover and then enter pump head.

Embodiment
The utility model is described in further detail with reference to embodiment and embodiment, but should not be by this
The scope for being interpreted as the utility model aforementioned body is only limitted to following embodiment, all to be realized based on the utility model content
Technology belongs to the scope of protection of the utility model.
As shown in Figures 2 and 3, the utility model is made up of filter hood 1, filter 2, fuel sucking pipe 3, and filter hood 1 is perpendicular
It is straight to be arranged in the oil sump of lubricating system, welded with lid 4 on the oil sump of lubricating system and carry out the encapsulation process such as daub, filter
2 are built in filter hood 1, and fuel sucking pipe 3 is fixedly connected with filter 2, the connecting end surface installation rubber of fuel sucking pipe 3 and filter 2
Glue sealing ring is sealed, and the length of filter 2 is more than the length of filter hood 1, between filter 2 and filter hood 1 between
Gap forms inlet port.
As shown in Fig. 2 the end of fuel sucking pipe 3 is connected with flange 1, flange 1 welds with fuel sucking pipe 3, with flange one
31 it is supporting have flange 2 32, flange 2 32 welds with the top of oil filter cover 1, and carries out encapsulation process, the bottom of flange 1 with
The top of oil filter 2 is fixedly connected and carries out encapsulation process, and flange 1 is fixedly connected with flange 2 32 by screw, flange 1
Seal groove one is machined with the joint face of flange 2 32, rubber seal, flange 1 and filter 2 are placed with seal groove one
It is fixedly connected by screw, the joint face of flange 1 and filter 2 is machined with seal groove two, and rubber is placed with seal groove two
Sealing ring.
