Background technology
TADY type multistage pump with the mechanical seal of Double End Ji Installed formula is one of alkylbenzene workshop instrument commonly used, the machine envelope of this multistage pump adopts the mode of API610 standard P LAN53B system flushing to make, the sealing of twice "O"-ring is arranged in the machine envelope, therefore to go lower machine envelope just very inconvenient during maintenance repair, as taking off by force careless slightly will the envelope by the destruction machine, cause waste, increase production cost.
Summary of the invention
The purpose of this utility model provides a kind of mechanical seal dismantling device of being convenient to take off machine envelope on the pump housing axle.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of mechanical seal dismantling device comprises lower cover die and top board, is provided with between described lower cover die and top board to be no less than two connecting rods; Described lower cover die middle part axially has through hole, and the bottom of lower cover die is provided with fixing hole; The top board middle part is provided with the jackscrew that runs through top board, and described jackscrew and top board are threaded connection, and drives top board when jackscrew rotates and moves axially.At the fixing hole place on the lower cover die machine sealing is fixed on the lower cover die, the axle of the pump housing contacts with jackscrew by the through hole on the lower cover die, the rotation jackscrew, top board is axially to moving away from lower cover die direction, jackscrew keeps tactile with being coupling of the pump housing simultaneously, lower cover die is spurred to the top board direction, until the machine envelope is disassembled, the machine envelope is stressed more even in this process, can not cause damage to the machine envelope.
As further improvement of the utility model, it is cylindric that described lower cover die is ladder, and the diameter on its top is greater than the diameter of bottom.This shape is convenient to evenly arrange connecting rod and fastening bolt, keeps simultaneously the even thickness of cover die under the fastening bolt place.
As further improvement of the utility model, described jackscrew top is provided with polygonal lever operated.The polygonal lever operated instrument such as convenient use spanner rotates jackscrew, and more convenient operation is laborsaving.
As further improvement of the utility model, described connecting rod has four, and these four connecting rods evenly distribute.Four equally distributed connecting rods make the machine envelope stressed more even, the damage of minimizing machine envelope.
As further improvement of the utility model, described connecting rod is stud, and its two ends are provided with nut.Use stud to change the connecting rod that is fit to according to the model of the pump housing and the length of axle, in order to use at the pump housing of different model.
As further improvement of the utility model, described stud and lower cover die are connected the mode of matched in clearance and are connected with top board.Matched in clearance is is more easily loaded and unloaded stud, changes more convenient.
As further improvement of the utility model, described stud and lower cover die and top board are threaded connection.The position of stud and lower cover die and top board is fixed, and reduces human error and causes machine envelope discontinuity.
Further improve as of the present utility model, described lower cover die bottom is provided with locating hole.Locating hole can be more convenient the bolt hole that fastening bolt and machine are sealed up be mapped, the fixing machine envelope is faster.
In sum, the beneficial effects of the utility model are: easy to use, can not cause damage to the machine envelope during use, and simple in structure, be convenient to make.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Embodiment one:
Such as Fig. 1 to mechanical seal dismantling device shown in Figure 5, comprise the columned lower cover die 1 of ladder and top board 2, described lower cover die 1 evenly arranges four connecting rod 4(studs with 2 on top board) be connected, the two ends of connecting rod 4 are respectively equipped with nut 8 and nut 9, and connecting rod 4 connects lower cover die 1 and top board 2 by the mode of matched in clearance; The diameter on lower cover die 1 top is greater than the diameter of bottom; Described lower cover die 1 middle part axially has through hole 6, and lower cover die 1 bottom is provided with fixing hole 7; Top board 2 middle parts are provided with the jackscrew 3 that runs through top board 2, and jackscrew 3 tops are provided with polygonal lever operated 10, and described jackscrew 3 drives top board 2 when rotating and moves axially.Described lower cover die 1 bottom is provided with locating hole 5, locating hole 5 and fixing hole 7 equally spaced arranged distribution.
Concrete using method is such: pass the through hole 6 with the axle of pump housing cover die 1 under this machinery sealing dismantling device, because the machine of the pump housing is sealed up and is left bolt hole, and the quantity of bolt hole is more than the quantity of fixing hole 7 corresponding with it on the lower cover die 1, the bolt hole correspondence that has more than fixing hole 7 down the locating hole 5 on the cover die, lower cover die 1 is enclosed within machine to be sealed up, observe locating hole 5 and bolt hole, during the position of locating hole 5 corresponding bolts hole, the machine sealing is fixed on the lower cover die 1 with bolt at fixing hole 7 places.Through hole 6 and jackscrew 3 deads in line, so the axle of the pump housing is over against this jackscrew 3, turn on the jackscrew 3 lever operated 10 with spanner, make being coupling of itself and the pump housing tactile, and be rotated further jackscrew 3, this moment, top board 2 beginnings were axially moved towards the direction away from pump housing axle along with the turn of jackscrew 3, and the mobile of top board 3 drives the lower cover die 1 of stud 4 pullings, thereby unloads the machine envelope.Also can not rotate jackscrew 3 in addition, but turn the nut 9 at top board 2 places or the nut 8 that lower cover die 1 goes out, also or simultaneously turn the nut 9 at top board 2 places and the nut 8 that lower cover die 1 goes out, make lower cover die 1 and top board 2 mobile in opposite directions, because jackscrew 3 is relative with pump housing axle static, and jackscrew 3 and top board 2 are fixed together by screw thread, so the axial top board 2 one sides pulling of the lower cover die 1 relative pump housing, band motivation envelope moves to top board 2 places, thereby the machine envelope is unloaded.
