Abstract
The utility model relates to the removing of a water pump, in particular to a removing device which is used for a centrifugal water pump. The device resolves the problem that the mode which is used to remove the centrifugal water pump at present is easy to damage the water pump. The device comprises a lead screw, a nut which is sheathed on the lead screw and is combined in screw threads with the lead screw, two traction rods. A hemispheric groove is opened at the centre of the end surface at one end of the lead screw, a ball is arranged in the hemispheric groove, two supporting parts which are vertical to the lead screw are symmetrically fixed on the nut, stripy via holes are opened on the supporting part along the radial direction of the nut. A retaining ring which is used to buckle processes on a part of the centrifugal water pump which is prepared to be removed is fixed at one end of the traction rod, screw threads are arranged on the rod body at the other side, and the rod body is provided in combining with a fastening nut. Two traction rods are respectively passed through the stripy via hole on two supporting parts correspondingly. The structure of the utility model is reasonable and compact, the using is safe, convenient and fast, the time, work and labor is saved. The sealing part among each section of pump body of the centrifugal water pump can not be damaged, therefore the maintenance cost is beneficial to be decreased. The device can be applicable to be used for the removing of various centrifugal water pumps widely.
Description
Technical field
The utility model relates to the water pump dismounting, specifically is a kind of Centrifugal water pump dismounting device.
Background technique
When Centrifugal water pump is overhauled; the inlet segment pump housing, the stage casing pump housing, the water exit end pump housing of Centrifugal water pump must be separated; at present use plain chisels, little sled more, instrument such as a sled or an axe cooperates that connection applies power to each section of Centrifugal water pump greatly; remove step by step after making each intersegmental matching loose; but make the sealed department bit loss of each section bad through regular meeting; cause gas leakage, leak and to use, can only scrap replacing, cause very big waste economically.
Summary of the invention
The utility model provides a kind of Centrifugal water pump dismounting device for the problem of the fragile water pump of mode that solves present dismounting Centrifugal water pump and adopt.
The utility model is to adopt following technological scheme to realize: the Centrifugal water pump dismounting device, comprise leading screw, be sheathed on the leading screw and with threads of lead screw nut engaged and two drawing pull bar; The central authorities of leading screw one end end face offer hemispherical groove, and hemispherical groove is built-in with ball; Be symmetrically fixed with two supporting elements vertical with leading screw on the nut, nut and last two supporting elements thereof constitute the double-vane shoulder, and supporting element upper edge nut radial direction offers the strip through hole; One end of described drawing pull bar is fixed with to be used for detaining and tangles the clasp that Centrifugal water pump is treated removable member (the inlet segment pump housing, the stage casing pump housing, the water exit end pump housing that refer to Centrifugal water pump) upper process, and the body of rod of opposite side is provided with screw thread, and is equipped with tightening nut; The corresponding respectively strip through hole that passes on two supporting elements of two drawing pull bar, and drawing pull bar is fixed with the same side that an end of clasp and a end that leading screw offers hemispherical groove are positioned at the double-vane shoulder.
During use, the end that leading screw is had a hemispherical groove withstands on the end face of Centrifugal water pump rotating shaft, and the ball in the hemispherical groove is just in time embedded in the groove of Centrifugal water pump rotating shaft end face; Then, unscrew the tightening nut on the drawing pull bar, adjust the position of two drawing pull bar along strip through hole direction, leading screw axial direction on the double-vane shoulder supporting element, the clasp of two drawing pull bar ends is buckled tangle Centrifugal water pump to treat projection on removable member (dismounting of Centrifugal water pump is generally carried out in proper order by the inlet segment pump housing, the stage casing pump housing, the water exit end pump housing) symmetrical position respectively, and screwed the tightening nut on the drawing pull bar; At last, application of force rotational lead screw, rotatablely moving of leading screw is converted to the straight line motion of double-vane shoulder, the supporting element of double-vane shoulder directly applies tractive force to drawing pull bar, make drawing pull bar treat that by Centrifugal water pump projection on the removable member outwards spurs Centrifugal water pump and treats removable member, realization is treated the dismounting of removable member can not cause damage to the sealing position between each section of Centrifugal water pump pump housing in the whole process to Centrifugal water pump; Each section pump housing at Centrifugal water pump repeats and then process, can finish the fractionation of each section of Centrifugal water pump pump housing successively, so that the pump housing of Centrifugal water pump is changed and overhauled.Wherein, the purpose that is provided with of hemispherical groove in leading screw end and ball cooperating structure is a resistance when reducing rotational lead screw, so that staff's operation.
The utility model is rational in infrastructure, compact, safe in utilization, convenient, save time, saving of labor, laborsaving.Can not cause damage, help reducing the cost of overhaul the sealing position between each section of Centrifugal water pump pump housing.Can be widely used in the dismounting of various Centrifugal water pumps.
