Description
Technical Field
The invention belongs to the technical field of mechanical equipment, and particularly relates to a maintenance tool for an oil transfer pump isolator.
Background
The oil transfer pump isolator mainly plays a role in bearing the bearing box and the shaft, lubricating oil in the bearing box body is prevented from overflowing in the high-speed operation process of the equipment, and the bearing ablation phenomenon of the equipment caused by oil shortage and dry friction is avoided. The separator is naturally aged and worn for a certain period of time, and the leakage of the lubricating oil is caused, and the separator is replaced. The current maintenance measures are to maintain the isolator in an integral replacement mode, and the replaced isolator is basically discarded.
The isolator body structure is made of stainless steel or copper materials and is divided into an inner ring and an outer ring. The isolator outer lane relies on the cooperation of external seal circle and bearing housing to be sealed, and the isolator inner circle relies on the inner seal circle to cooperate with the axle and rotate along with the axle, is equipped with floating seal circle between isolator inner circle and the outer lane, and floating seal circle is the sealing washer that plays decisive role to the sealed condition of isolator, and is very fast along with the high-speed rotatory wearing and tearing of equipment.
Because the high-speed rotation of equipment, the wearing parts of the isolator are mainly three sealing rings of an inner sealing ring, an outer sealing ring and a floating sealing ring, and the isolator body does not participate in wearing, so that the isolator is not easy to damage.
Because the floating seal circle is installed between isolator inner circle and outer lane, so change the floating seal circle of isolator and need dismantle the isolator, do not have the professional repair tools to the isolator dismouting in the existing market, adopt current instrument plain end screwdriver, flexible stick etc. to prize the dismantlement, it is harder, and can damage isolator stainless steel or copper body. Therefore, a special tool is required to be manufactured according to the structure of the isolator to disassemble and assemble the isolator.
Disclosure of Invention
In order to meet the requirements, the invention provides the maintenance tool for the oil transfer pump isolator, which can be used for quickly disassembling the isolator and conveniently replacing three sealing rings, so that the production cost is greatly reduced.
The technical scheme includes that the maintenance tool for the oil transfer pump isolator comprises a workbench, a jack, a chuck A and a chuck B, wherein the jack is fixed on the workbench, a top rod of the jack is provided with a tray, the chuck A is arranged on the tray, an inverted L-shaped support is arranged on the workbench, the transverse edge of the L-shaped support is parallel to the workbench, and the chuck B is inverted at the bottom of the transverse edge of the L-shaped support.
Preferably, be equipped with outer clamp frock on the chuck A, the structure of outer clamp frock is: each clamping jaw of the chuck A is fixed with a clamping piece, and each clamping piece is provided with an arc-shaped notch; be equipped with the internal stay frock on the chuck B, the structure of internal stay frock is: and each clamping jaw of the chuck B is fixedly provided with a supporting piece, and each supporting piece is provided with a round angle.
Preferably, the clamping piece is fixed on the clamping jaw on the chuck A in the following mode: the clamping jaw is provided with a threaded hole, the clamping piece is provided with a through hole, and the clamping piece is fixed on the clamping jaw through the through hole on the clamping piece by a screw; the mode that the supporting sheet is fixed on the clamping jaw on the chuck B is as follows: the clamping jaw is provided with a threaded hole, the supporting piece is provided with a through hole, and the supporting piece is fixed on the clamping jaw by a screw penetrating through the through hole on the supporting piece.
Preferably, the jack is a screw jack.
When the isolator needs to be disassembled, the outer ring of the isolator is placed into the outer clamping tool, the clamping jaws of the chuck A are tightened, clamping pieces of the outer clamping tool clamp the outer ring of the isolator, then the ejector rod of the screw jack is rotated upwards, the inner supporting tool is sleeved in the inner ring, the clamping jaws of the chuck B are expanded outwards, supporting pieces of the inner supporting tool support the inner ring of the isolator, then the ejector rod of the screw jack is rotated downwards, the inner ring and the outer ring are separated by utilizing the pulling force of the jack, then a floating seal ring between the inner ring and the outer ring can be taken out, and after the replacement is successful, the ejector rod of the screw jack which is rotated upwards can be used for installing the inner ring and the outer ring.
The outer clamping tool and the inner supporting tool are adopted, instead of directly using the clamping jaws of the chuck to carry out outer clamping and inner supporting, so that the contact surfaces between the clamping tool and the isolator body as well as the inner supporting tool are increased, the pressure is reduced, and the isolator body is prevented from being damaged by clamping during operation.
The screw jack is convenient to use and low in purchase cost because the ejector rod of the screw jack can generate large force when being stretched.
The invention has the beneficial effects that: the isolator can be quickly disassembled and assembled, and then three sealing rings are conveniently replaced, so that the production cost is greatly reduced.
