Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tool equipment, in particular to a plunger pump cylinder liner disassembly device. Background Technique

[0002] High-pressure plunger pumps are widely used in the polysilicon production industry due to their high working pressure, rapid response, and stable operation. Bell jar cleaning is a very important link in the polysilicon production field. The cleanliness of the bell jar cleaning directly affects the quality of polysilicon. The cleanliness of the bell jar cleaning depends on the working condition of the high-pressure plunger pump and the timeliness of maintenance. Due to the relatively high working pressure and the working medium being lye, the wear of the packing on the cylinder liner will be aggravated. There is no special tool for replacing the cylinder liner, which delays the maintenance progress during the maintenance and replacement process and affects normal production.

[0003] Due to the relatively high pressure during the use of the high-pressure plunger pump, the fitting clearance of the cylinder liner installation is relatively small. If damage occurs and replacement is required, disassembly is also very inconvenient. The existing disassembly methods mainly use a hammer or a copper bar for manual knocking and removal. If jamming or sticking occurs, oxyacetylene heating with fire is required to expand and remove it. However, when using the knocking method to remove the cylinder liner, it is easy to cause damage to the installation position of the cylinder liner. During knocking, the cylinder liner is prone to jamming, mainly due to uneven knocking force. Therefore, the disassembly work requires very high maintenance experience from the operator, relatively large personnel input, and increases the maintenance time during the cylinder liner replacement process, reducing the overall production efficiency.

Compared with the prior art, when using a rammer or a copper bar for manual knocking and removing, if there is jamming or sticking, it is necessary to use oxyacetylene for heating by fire to make it expand and remove. However, when using the knocking method to remove the cylinder liner 92, it is easy to cause damage to the installation position of the cylinder liner 92. During the knocking, the cylinder liner 92 is prone to jamming, mainly because the knocking force is uneven. Therefore, the disassembly work requires very high maintenance experience for the operators, and the personnel input is relatively large.

In this technical solution, by clamping the chuck component 21 at the edge position of the cylinder liner 92, then installing the second nut 22 on the shaft body 11 so that the second nut 22 abuts against the chuck component 21, then passing the shaft body 11 through the cylinder liner 92, installing the first disc body 12 at one end of the shaft body 11 away from the chuck component 21, then installing the first nut 13 on the shaft body 11, and the other end of the abutting component abuts against one end of the cylinder block 91, rotating the first nut 13, using the pre-tightening force of the first nut 13 to make the chuck component 21 move towards the direction of the first disc body 12, so that the cylinder liner 92 gradually disengages from the cylinder block 91 along the axial direction of the shaft body 11, which can not only quickly disassemble the cylinder liner 92, but also prevent the cylinder liner 92 from getting stuck in the cylinder block 91, thus achieving the technical effects of reducing labor intensity and improving maintenance efficiency.

[0026] The above-mentioned body includes a shaft body 11, a first disc body 12 and a first nut 13.
