Abstract
The utility model discloses a reciprocating type plunger equipment crankcase oil blanket of offshore platform, including seal shell, the seal shell outside is provided with the outer seal ring, be provided with two skeleton oil blanket in seal shell's the cavity, seal shell's top is provided with the gland through the connecting piece is fixed, the gland is impressed the one end of seal shell and is offseted with the skeleton oil blanket; a first sealing ring is arranged in the gland, and a second sealing ring is arranged between the gland and the sealing shell. The utility model aims at providing a lubricating oil that can solve in the equipment power end crankcase causes the problem of revealing through oil blanket department, installs simple sealed effectual crankcase oil blanket.
Description
Technical Field
The utility model relates to an oil blanket technical field especially relates to a reciprocating type plunger equipment crankcase oil blanket of offshore platform.
Background
In the reciprocating type water injection equipment long-term service of offshore oil production platform, be provided with a plurality of skeleton oil seals in the oil blanket, the skeleton oil blanket internal spring can be strutted when inside cavity pressure is too big, causes sealed inefficacy, causes the lubricating oil in the crankcase to produce through oil blanket department and reveals or lead to on-the-spot environmental pollution, and the lubricating oil consumption is great, and outside medium also gets into in the oil blanket through the pole that connects of reciprocating type water injection equipment easily in addition. Therefore, the problem that lubricating oil in the power end crankcase of the equipment leaks through the oil seal is solved, and the crankcase oil seal which is simple to install and good in sealing effect is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the above-mentioned prior art, aim at providing one kind and can solve the lubricating oil in the equipment power end crankcase and lead to the fact the problem of revealing through oil blanket department, install simple sealed effectual crankcase oil blanket.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
a crankcase oil seal of an offshore platform reciprocating plunger device comprises a seal shell, wherein an outer sealing ring is arranged outside the seal shell, two framework oil seals are arranged in a cavity of the seal shell, a gland is fixedly arranged at the top end of the seal shell through a connecting piece, and the gland is pressed into one end of the seal shell to abut against the framework oil seals; a first sealing ring is arranged in the gland, and a second sealing ring is arranged between the gland and the sealing shell.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses reduce the skeleton oil blanket into two and increase the gland and compress tightly the skeleton oil blanket, make the first sealing washer on the gland receive the rigidity support of gland when internal pressure is big not can be strutted, still can play sealed effect, block in outside medium gets into the crankcase. Meanwhile, the gland can improve the safety and reliability of equipment in operation, and avoids the displacement of the framework oil seal caused by loosening of the framework oil seal or high pressure of a cavity.

Fig. 1 is a schematic structural diagram of the present invention.
Reference numerals are as follows:
1-a sealed shell, 2-a connecting piece, 3-a gland, 4-a first sealing ring, 5-a second sealing ring, 6-a framework oil seal and 7-an outer sealing ring.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1, the crankcase oil seal of the offshore platform reciprocating plunger device comprises a seal housing 1, wherein an outer sealing ring 7 is arranged outside the seal housing 1, two framework oil seals 6 are arranged in a cavity of the seal housing 1, a gland 3 is fixedly arranged at the top end of the seal housing 1 through a connecting piece 2, and one end of the gland 3 pressed into the seal housing 1 is abutted against the framework oil seals 6; a first sealing ring 4 is arranged in the gland 3, and a second sealing ring 5 is arranged between the gland 3 and the sealing shell 1.
The utility model discloses the oil blanket is applied to and is straight reciprocating motion with reciprocating type water injection equipment's extension rod, and seal housing 1 is sealed through the connecting end of outer seal ring 7 with the crankcase. The first sealing ring 4 is arranged in the gland 3 and used for forming shaft sealing with a connecting rod of reciprocating water injection equipment, and the surface of the connecting rod keeps smooth due to the fact that the relative motion form between the first sealing ring 4 and the reciprocating connecting rod is linear reciprocating motion, abrasion between the connecting rod and the sealing shell 1 is reduced, and the cleaning effect is achieved. And the first sealing ring 4 is matched with the connecting rod in a sealing manner, so that the connecting rod can be prevented from bringing water into the sealed shell 1, and the lubricating oil in the sealed shell 1 is prevented from being emulsified.
The first sealing ring 4 on the gland 3 is supported by the gland 3 when the internal pressure is high, and can not be spread, and the sealing effect can still be achieved. The framework oil seal 6 is reduced to two parts, and then the pressing cover 3 is pressed to improve the safety and reliability of the equipment in operation, so that the framework oil seal 6 is prevented from being displaced due to loosening or high chamber pressure. The second sealing ring 5 between the gland 3 and the sealing shell 1 can effectively prevent the lubricating oil in the crankcase from leaking, and meanwhile, the external water medium is prevented from entering the oil seal to pollute the lubricating oil.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
