Abstract
The utility model relates to a plunger pump oil blanket handling instrument. The oil seal pressing device consists of an oil seal taking-out tool and a pressing-in tool. The taking-out tool consists of a lifting ring and a lifting hook. The inner diameter of the lifting ring is 0.1-0.3 mm larger than the pump rod. The end surface of the lifting ring is vertically fixed with a lifting hook, and the length of the lifting hook is between 40 and 100 millimeters. The lifting hook is provided with a sharp tip and a barb. The sharp center can penetrate into the oil seal; the pressing tool is a pressing tube. The length of the pressing pipe is between 60 and 150 millimeters, the inner diameter of the pressing pipe is 0.1 to 0.3 millimeter larger than the outer diameter of the pump rod, and the outer diameter is 1 to 2 millimeters smaller than the inner diameter of the pump body. When the tool is used for assembling and disassembling the oil seal, the oil seal is uniformly stressed and can be stably taken out or smoothly installed, and the production efficiency is effectively improved.
Description
Affiliated technical field
This utility model relates to a kind of specific purpose tool that keeps in repair plunger displacement pump, particularly a kind of specific purpose tool of dismounting plunger displacement pump oil sealing.
Background technology
When the maintenance plunger displacement pump, run into: dismounting plunger displacement pump oil sealing or installation plunger displacement pump oil sealing through regular meeting.Because the annular space between the pump housing and the pump rod is narrow and small, the position at oil sealing place is dark, is difficult to the oil sealing of corrupted is taken out from narrow and small annular space; It is equally also very difficult that oil sealing is installed.The annular space at oil sealing place is narrow and small to be a reason that causes the loading and unloading difficulty, and Another reason is that because the oil sealing discontinuity, oil sealing is inclined in the loading and unloading oil sealing.No matter cause is that oil sealing is installed, and it is all very difficult still to dismantle oil sealing.
The utility model content
The purpose of this utility model is: a kind of plunger displacement pump oil sealing handling instrument is provided, and this instrument mainly is that the annular space that overcomes between the pump housing and the pump rod is narrow and small, and during the loading, unloading oil sealing, the oil sealing discontinuity causes oil sealing to tilt, and is difficult to the difficulty of loading, unloading oil sealing.When realizing oil sealing is installed, oil sealing is evenly stressed, steadily arrives the annular space bottom of the pump housing and pump rod; During the dismounting oil sealing, oil sealing is evenly stressed, successfully takes out from the annular space bottom.
Technical solution adopted in the utility model is: taken out instrument and be pressed into instrument by oil sealing and form.The taking-up instrument is made up of drop handle and lancet.Drop handle is the hollow cylinder bodily form, and the drop handle internal diameter is greater than pump rod 0.1-0.3 millimeter.The end face vertical fixing of drop handle has lancet, and lancet length is between the 40-100 millimeter.The fixed form of lancet and drop handle can be welding, also can be to be threaded.Lancet has sharp keen top, and hangnail is arranged.Sharp keen toply can thrust in the oil sealing; On when carrying, the lancet hangnail carries oil sealing and steadily moves up, and oil sealing is taken out from annular space.The instrument of being pressed into is an ascending pipe.The length of ascending pipe is between the 60-150 millimeter, and the ascending pipe internal diameter is greater than pump rod external diameter 0.1-0.3 millimeter, and the ascending pipe external diameter is less than pump housing internal diameter 1-2 millimeter.The ascending pipe end face is vertical with center line.When oil sealing is installed, oil-sealing sleeve on pump rod, vertically is pressed into annular space with ascending pipe with oil sealing.
Useful effect of the present utility model is: when oil sealing was installed, oil sealing was evenly stressed, steadily arrived the annular space bottom of the pump housing and pump rod; During the dismounting oil sealing, oil sealing is evenly stressed, successfully takes out from the annular space bottom.
Accompanying drawing and brief description
Accompanying drawing 1 is to utilize oil sealing taking-up instrument to take out the generalized section of oil sealing.
Accompanying drawing 2 is to utilize oil sealing to be pressed into the generalized section that instrument is pressed into oil sealing annular space.
Among the figure: 1. drop handle, 2. lancet, the 3. pump housing, 4. oil sealing, 5. pump rod, 6. ascending pipe.
The specific embodiment
Embodiment: see accompanying drawing 1, drop handle (1) is the hollow cylinder bodily form, and drop handle (1) internal diameter is greater than (5) 0.2 millimeters of pump rods.The end face of drop handle (1) is vertical, be symmetrically fixed with 2 lancets (2).Lancet (2) is that diameter is 4 millimeters a cylinder, and length is 60 millimeters.Fixed form is welding.The top of lancet (2) has sharp keen top, and 1 hangnail is arranged.See accompanying drawing 2, the length of ascending pipe (6) is 80 millimeters, and ascending pipe (6) internal diameter is greater than 0.2 millimeter of pump rod (5) external diameter, and ascending pipe (6) external diameter is less than 1.5 millimeters of the pump housing (3) internal diameters.Ascending pipe (6) end face is vertical with center line.Using method is fairly simple, is not described in detail.This instrument of employing takes out a cover oil sealing (4), only uses 5 fens clock times.And before this instrument of employing, getting a cover oil sealing (4) needs 2 hours.Improved production efficiency effectively.
Claims (4)
1, a kind of plunger displacement pump oil sealing handling instrument, be mainly used in dismounting plunger displacement pump oil sealing, it is characterized in that: drop handle (1) is the hollow cylinder bodily form, drop handle (1) internal diameter is greater than pump rod (5) 0.1-0.3 millimeter, the end face vertical fixing of drop handle (1) has lancet (2), lancet (2) length is between the 40-100 millimeter, lancet (2) has sharp keen top, and hangnail arranged, the length of ascending pipe (6) is between the 60-150 millimeter, ascending pipe (6) internal diameter is greater than pump rod (5) external diameter 0.1-0.3 millimeter, and ascending pipe (6) external diameter is less than the pump housing (3) internal diameter 1-2 millimeter, and ascending pipe (6) end face is vertical with center line.
2, plunger displacement pump oil sealing handling instrument as claimed in claim 1 is characterized in that: lancet (2) is welding with drop handle (1) fixed form.
