Abstract
The utility model provides a replacing device of a reciprocating type plunger pump sealing member, which belongs to a tool and has a holding frame which is connected with a fixed claw with a slot by a connecting rod, a lead screw is arranged at the middle part of the holding frame, a righting plate is disposed at the middle and upper part of the lead screw, and a stopper end is arranged at the lower end thereof. The replacing device of the sealing member has advantages of simple and reasonable structure, convenient use, time and labor saving, high work efficiency and safe operation, and the extracted guide sleeve can be reused, so maintenance costs are reduced.
Description
Technical field
The utility model provides a kind of instrument, especially a kind of instrument of changing the seal on the plunger displacement pump.
Background technology
Employed reciprocating plunger pump in the present field produces, its working media is a sewage, the impurity content height, corrosivity is strong.Just need to safeguard behind the work certain hour, change seal.Packing is arranged and to the passive fairlead of packing on the seal.The method of existing taking-up seal is, utilizes instruments such as sledgehammer, crowbar, fairlead impacted and with its taking-up by manpower.Operation inconvenience is wasted time and energy, and causes injury to personnel in the operating process easily.And impacting the fairlead that takes out the back can not reuse because of damage.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of more changing device of reciprocating plunger pump seal, to improve the convenience that seal is changed.
The utility model is to realize like this, the more changing device of reciprocating plunger pump seal, it has bracing frame, and bracing frame links together by the fixed claw of connecting rod with the band draw-in groove, the bracing frame middle part is equipped with leading screw, and the middle and upper part of leading screw is equipped with righting board, the lower end is equipped with chock plug.
Adopt the more changing device of the reciprocating plunger pump seal of said structure, simple and reasonable for structure, easy to use, time saving and energy saving, high efficiency, handling safety, the fairlead of taking-up is reusable, has reduced maintenance cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.
As shown in drawings, the more changing device of the reciprocating plunger pump seal of the utility model, it has bracing frame 2, and bracing frame links together by the fixed claw 5 of connecting rod 4 with the band draw-in groove, the bracing frame middle part is equipped with leading screw 3, and the middle and upper part of leading screw is equipped with righting board 1, the lower end is equipped with chock plug 7.
When being used to pull down the packing on fairlead and the fairlead, with fixed claw be placed in the pump housing 8 above, the draw-in groove on the fixed claw is stuck on the bolt 6 on the pump housing, fixes by nut then.Righting board is positioned at the fairlead installing hole on the pump housing, plays a supporting role.Rotational lead screw withstands on the fairlead to be removed chock plug, and further rotational lead screw just can eject the pump housing together with packing with the fairlead as seal.Unload chock plug, the fairlead of changing new packing is installed in chock plug outside after, again chock plug is fixed on the leading screw.The counter-rotation leading screw makes its pulling fairlead get back to original installation site then.Then, pull down this more changing device, finish the replacing of seal.
Hinged between bracing frame and connecting rod, connecting rod and the fixed claw by hinge, can adapt to the different plunger displacement pump of spacing between the bolt 6 like this.
