Abstract
The utility model provides a spanner of a pressing cover of a plunger piston pump, which is applied to the repair and the maintenance of the plunger piston pump. A handle, an arc plate and a hook head are formed by cutting a steel plate with 8-10mm, the diameter of the inner arc surface of the arc plate is as the same as the outer diameter of the pressing cover of a sealed coiled root of the plunger piston pump, the inner arc surface of the arc plate is provided with two rectangular hook heads, the centre lines of the two hook heads are intercrossed at the center of the inner arc surface of the arc plate, and the inclined angle between the centre lines of the two hook heads is 120 degrees. The outer arc surface of the arc plate is provided with the handle. The spanner has the benefits of being convenient to adjust the pressing cover of the sealed coiled root of the plunger piston pump, and enlarging the thrust surface of the spanner, reducing the slippage phenomenon of the spanner, and reducing the damage of the pressing cover compared with the existing spanner. The spanner can be experimentally used for debugging the five high-pressure plunger piston pumps, completely eradicates the conditions that the pressing cover is broken and slipped, and prevents the pressing cover from being scrapped since a notch of the pressing cover is damaged by the hook heads.
Description
Technical field
The utility model relates to the maintenance of plunger displacement pump, is a kind of adjustment specific purpose tool of high-pressure plunger pump sealed packing gland.
Background technology
The connecting-rod head of high-pressure plunger pump has sealed packing, in the outside of sealed packing gland is arranged.The rotation gland can compress the sealing that sealed packing improves plunger displacement pump.On the outer wall of gland, be evenly distributed with groove.The instrument of original rotation gland is a rod iron, is one section cubic cylinder that can insert the gland groove on the caput.The four directions cylinder inserts in the groove, pulls rod iron rotation gland, and the gland stress surface is inhomogeneous like this, and the instrument material is hard, during work and the contact area of gland little.For the protection to the packing screw thread, packing gland is made of Cu alloy material, and material is softer, easily causes damage when adjusting gland.
The utility model content
The purpose of this utility model is: a kind of plunger displacement pump gland spanner is provided, can adjusts the sealed packing gland of plunger displacement pump easily, the minimizing instrument is to the infringement of gland.
The technical solution adopted in the utility model is: plunger displacement pump gland spanner, mainly form by handle, cambered plate and eave tile, it is characterized in that: handle, cambered plate and eave tile are to adopt the steel plate cutting of 8～10mm to form, the inner arc surface diameter of cambered plate is identical with the sealed packing gland external diameter of plunger displacement pump, and the width of cambered plate is between 20～40 millimeters; Two rectangular eave tiles are arranged on the inner arc surface of cambered plate, and the width of eave tile is at 5～12 millimeters, and length is at 8～20 millimeters.The center line of two eave tiles intersects at the center of cambered plate inner arc surface, and the center line angle of two eave tiles is 120 degree.Exterior arc surface at cambered plate has a handle.Manufacturing process is to rule on steel plate, marks cambered plate, handle and eave tile, and by the setting-out cutting, so the thickness of cambered plate, handle and eave tile is identical.
Described handle can be in the exterior arc surface middle part of cambered plate, and handle also can be in the end of exterior arc surface.Handle when the end of exterior arc surface, similar common tool eave tile spanner (colluding the type spanner).
The beneficial effects of the utility model: the utility model plunger displacement pump gland spanner, can adjust the sealed packing gland of plunger displacement pump easily, compare the stress surface that has strengthened spanner with former instrument, eliminated the slip phenomenon of spanner, reduced infringement to gland.On probation in five high-pressure plunger pump debugging work, stopped gland and damaged and the slippage situation, do not take place to cause gland to scrap phenomenon because of eave tile damages the gland notch.
Description of drawings
Fig. 1 is the utility model plunger displacement pump gland spanner structure schematic diagram.
Fig. 2 is the another kind of structural representation of plunger displacement pump gland spanner.
Among the figure, 1. handle, 2. cambered plate, 3. eave tile.
The specific embodiment
Embodiment 1: with the plunger displacement pump gland spanner of a handle 1 in the exterior arc surface middle part of cambered plate 2 is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model plunger displacement pump gland spanner mainly is made up of handle 1, cambered plate 2 and eave tile 3.Handle 1, cambered plate 2 and eave tile 3 are to adopt the block plate cutting of 8mm to be in the same place, and cambered plate 2, handle 1 are identical with the thickness of eave tile 3.The inner arc surface diameter of cambered plate 2 is identical with the sealed packing gland external diameter of plunger displacement pump.The width of cambered plate 2 is 30 millimeters, and the cambered surface angle of cambered plate 2 is 140 degree; Two rectangular eave tiles 3 are arranged on the inner arc surface of cambered plate 2, and the width of eave tile 3 is 10 millimeters, and length is 18 millimeters.The center line of two eave tiles 3 intersects at the center of cambered plate 2 inner arc surfaces, and the center line angle of two eave tiles 3 is 120 degree.Exterior arc surface at cambered plate 2 has a handle 1, and handle 1 is in the exterior arc surface middle part of cambered plate 2,350 millimeters of the length of handle 1, and width is 35 millimeters.Two eave tiles 3 just insert in two grooves in the sealed packing gland outside of plunger displacement pump.Pull handle 1 the sealed packing gland of plunger displacement pump is rotated, can unclamp or enterprising gland.
Embodiment 2: consult Fig. 2.Embodiment 2 is substantially the same manner as Example 1, and difference is the end of handle 1 at exterior arc surface.
Claims (3)
