Technical Field
The utility model relates to the technical field of multistage pump assembly, in particular to a multistage pump impeller wedge key hydraulic dismounting device.
Background
When the impeller of the multistage pump is assembled, the impeller is fixedly arranged on the shaft by driving a wedge key, and the surface of the wedge key generates a large pretightening force so as to transmit torque by virtue of friction force during working and bear unidirectional axial force; when the impeller needs maintenance and replacement, the wedge-shaped key on the impeller needs to be removed, and because a large pretightening force is generated between the wedge-shaped key and the impeller, the impeller or the shaft is easily damaged in a violent removing mode in the process of removing the wedge-shaped key; it is necessary to provide a multistage pump impeller wedge key hydraulic dismounting device.
Disclosure of Invention
The utility model aims to solve the problems and provides a multistage pump impeller wedge key hydraulic dismounting device.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the hydraulic oil cylinder is characterized by further comprising a piston cylinder arranged on the oil cylinder body and a pull tube arranged on the oil cylinder body, wherein a reset seat matched with the oil cylinder body is arranged on the piston cylinder.
Preferably, an oil cavity is formed between the oil cylinder main body and the piston cylinder, and a quick connector communicated with the oil cavity is arranged on the oil cylinder main body.
Preferably, the piston cylinder is provided with an inner sealing ring and an outer sealing ring which are matched with the cylinder body.
Preferably, a spring is arranged between the reset seat and the piston cylinder, one end of the spring is connected with the reset seat, and the other end of the spring is connected with the piston cylinder.
Preferably, the reset seat is provided with a positioning groove which is convenient for installing the spring.
The utility model has the beneficial effects that: through the arrangement of the device, the pull pipe is connected with the wedge-shaped key and the oil cylinder main body, and the oil cylinder main body is used for pulling the pull pipe to rapidly dismount the wedge-shaped key, so that the operation is simple and convenient;
through the arrangement of the quick connector, the oil pump is separated from the oil cylinder main body, so that the oil cylinder main body is small in size and convenient to carry, the wedge-shaped key can be removed in a narrow space, and the removal efficiency is improved;
through setting up of reset seat, the hydro-cylinder main part is accomplished the back of operation, and on reset seat was reset to the hydro-cylinder main part through the restoring force of spring to make the hydro-cylinder main part return fast.
Drawings
Fig. 1 is a schematic diagram of the overall structure of the present utility model.
The marks in the figure are as follows: 1 an oil cylinder main body, 11 quick-mounting joints, 2 a piston cylinder, 21 an inner sealing ring, 22 an outer sealing ring, 3 a pull tube, 4 a reset seat, 41 springs and 42 positioning grooves.
Detailed Description
The utility model further provides a multistage pump impeller wedge key hydraulic dismounting device by means of embodiments and with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides a multistage pump impeller wedge key hydraulic dismounting device, which comprises an oil cylinder main body 1, and is characterized by further comprising a piston cylinder 2 movably mounted on the oil cylinder main body 1, a pull tube 3 which is mounted on the oil cylinder main body 1 through threads, wherein a reset seat 4 which is matched with the oil cylinder main body 1 is mounted on the piston cylinder 2 through threads, an oil cavity 5 is formed between the oil cylinder main body 1 and the piston cylinder 2, a quick-mounting joint 11 which is communicated with the oil cavity 5 is arranged on the oil cylinder main body 1, an inner sealing ring 21 and an outer sealing ring 22 which are matched with the oil cylinder main body 1 are mounted on the piston cylinder 2, a spring 41 is mounted between the reset seat 4 and the piston cylinder 2, one end of the spring 41 is connected with the reset seat 4, the other end of the spring 41 is connected with the piston cylinder 2, and a positioning groove 42 which is convenient for mounting the spring 41 is arranged on the reset seat 4; through the arrangement of the device, the pull tube 3 is connected with the wedge-shaped key and the oil cylinder main body 1, and the oil cylinder main body 1 is started by the oil pump, so that the oil cylinder main body 1 pulls the pull tube 3 to quickly detach the wedge-shaped key from the impeller, and the operation is simple and convenient; through the arrangement of the quick connector 11, the oil pump is separated from the oil cylinder main body 1, the oil cylinder main body 1 is small in size and convenient to operate, the wedge-shaped key can be detached in a narrow space, and the detachment efficiency is improved; through setting up of reset seat 4, cylinder main part 1 is accomplished the back of operation, and the restoring force through spring 41 resets cylinder main part 1 to reset seat 4 to make cylinder main part 1 return fast.
In actual use, the pull tube 3 is firstly arranged on the detached wedge-shaped key in a threaded manner, the other end of the pull tube 3 is arranged on the oil cylinder main body 1 in a threaded manner, the connection between the oil cylinder main body 1 and the wedge-shaped key is completed, the oil pump connecting tube is arranged on the quick connector 11, the oil pump is started to enable the oil cylinder main body 1 to act, hydraulic oil enters the oil cavity 5 through the quick connector 11, so that the piston cylinder 2 is pushed out forwards and is pushed against the impeller, the piston cylinder 2 is limited on the impeller along with the continuous injection of the hydraulic oil into the oil cavity 5, so that the oil cylinder main body 1 moves in the opposite direction of the piston cylinder 2, the pull tube 3 is driven to move along with the oil cylinder main body 1, and the wedge-shaped key is separated from the impeller.
The above embodiments are illustrative of the present utility model, and not limiting, and any simple modifications of the present utility model fall within the scope of the present utility model.
