Abstract
The invention discloses a tool for removing a pipe seat from the inlet valve chamber of a main pump, which comprises a regulating nut, a supporting piece, a screw rod, a connecting nut and a pulling piece, wherein the pulling piece is used to be fastened on the inner wall of the pipe seat when the pipe seat is removed; the pulling piece is fixed with the connecting nut; the supporting piece is used for supporting from the outside of the valve chamber when the pipe is removed; the supporting piece is provided with a through hole; the screw rod can pass through the through hole to be connected to the connecting nut; the regulating nut is sleeved on the free end of the screw rod; and when the pipe seat is removed, the screw rod is driven to move outward by the regulation of the regulating nut. When the removing tool of the invention is used for removing the pipe seat, high temperature is avoided, so influences on the valve chamber and damages to the pipe seat are avoided; the pipe seat removed can be used continuously after being processed; and the tool is simple in structure, small in volume and convenient to use.
Description
Technical field
The invention belongs to machinery and material field, be specifically related to the taking-up instrument of base in a kind of pump intake valve chamber.
Background technology
At present in the slurry pipeline transportation, employed equipment is the strange good positive discharge capacity membrane pump of TZPM1600 type, carrying out in the process of this pump, base in the main pump inlet valve chamber, behind the valve chamber of packing into, and the gap between the valve chamber is very little, add base and directly bearing the above periodical impulse force of cover plate 200kg that enters the mouth, high pressure at main pump, behind the long-play, between base and the valve chamber, because ore pulp or base are come the influence of the factors such as distortion that produce after the repercussion, are difficult to take out, could take out after can only utilizing the mode of flame cutting that the base cutting is come sometimes.
The existing problem of this cutting mode is, it also makes valve chamber be heated when cutting base open, produces stress, and even more serious is in the time of the cutting base, directly to cut to valve chamber probably, because base itself just pastes most valve chamber.
Cut base so repeatedly, the efficient of maintenance is reduced greatly, cost increases, and makes the valve chamber distortion easily, finally causes valve chamber to be scrapped.
Summary of the invention
The object of the present invention is to provide a kind of taking-up instrument of pipe seat from inlet valve chamber of main pump, this instrument can solve pipe seat from inlet valve chamber of main pump and be difficult to normal problem of taking out.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of taking-up instrument of pipe seat from inlet valve chamber of main pump, comprise and adjust nut, support member, screw rod, attaching nut and tensile elements, described tensile elements is used for being buckled in the inwall of base when taking out base, on tensile elements, be fixed with described attaching nut, described support member is used for being supported on the outside of valve chamber when taking out base, one through hole is arranged on support member, screw rod can pass this through hole and be connected among the attaching nut, adjust the free end of nut sleeve at screw rod, when taking out base,, drive screw rod and outwards move by adjusting the adjustment of nut.
Wherein support member and tensile elements adopt high-intensity steel plate or steel pipe to make.Support member specific thrust spare is long.
Further, the attaching nut is fixed by welding on the tensile elements.
Further, described screw rod and attaching nut can be replaced by the screw that comprises screw rod and nut.
Adopt taking-up instrument of the present invention to take out base and utilize the flame cutting mode to cut base open to compare, have following beneficial effect:
(1) because the present invention does not produce high temperature, so can not exert an influence to valve chamber, also can not damage base, the base that is taken out can also continue to use after treatment.
(2) because the present invention is simple in structure, and volume is little, and it is very convenient to use, thus operating efficiency than using flame cutting mode height, and kit can use repeatedly, cost is extremely low.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Disclose the taking-up instrument of pipe seat from inlet valve chamber of main pump of the present invention among Fig. 1, it comprises adjusts nut 1, support member 2, screw rod 3, attaching nut 4 and tensile elements 5.Attaching nut 4 and tensile elements 5 are fixed together by welding, have a through hole, screw rod 1 can pass this through hole on support member 2 and are connected among the attaching nut 4, adjust the other end that nut 1 is enclosed within screw rod.Wherein support member 2 and tensile elements 5 can adopt high-intensity steel plate or steel pipe.Usually support member 2 wants specific thrust spare 5 longer, and attaching nut 4 is welded on the centre position of tensile elements 5, and the through hole on the support member 2 also is positioned at the centre position.
During work, described pulling force portion 5 is buckled on the inwall of base, support member 2 is supported on the outside of valve chamber, screw rod 3 passes support member 2 and is connected with attaching nut 4, by adjusting the adjustment of nut 1, drive screw rod and outwards move, outwards move and then the take-off pipe seat thereby drive base.
