Product Introduction of Flange Spring Gasket
Flange spring washers are matching fasteners used in the flange connection and fastening parts of plunger pumps. They are mainly installed at the force-bearing positions of flange connection bolts or nuts and are used in conjunction with bolts, nuts and flange assemblies. After assembly, the spring washer generates a certain elastic effect and can be used to assist in maintaining the pre-tightened state of the threaded connection, reducing the adverse effects of factors such as equipment operation vibration and load changes on the tight connection.
During continuous operation, the plunger pump will generate periodic loads and mechanical vibrations. The flange connection position needs to be kept in a reliable and tight state. As an auxiliary part of the fastening assembly, the flange spring washer needs to match the specifications of the connecting bolts, nuts and flange installation holes. The installation status will also affect the usage effect of the entire fastening assembly.
The flange structure, bolt diameter and fastening requirements of different models of plunger pumps may vary. Therefore, the flange spring gasket should be selected according to the original equipment design specifications and should not be replaced merely based on appearance or approximate dimensions.
The main function of flange spring gaskets
1. Auxiliary anti-loosening: After assembly, the spring washer utilizes its own elastic characteristics to act on the connection position of the nut or bolt, and can be used as an auxiliary anti-loosening component in the threaded fastening structure.
2. Maintain a tight state: Used in conjunction with bolts and nuts, it assists in maintaining the pre-tightening state of the connection parts during equipment operation, and is suitable for the corresponding flange fastening positions of plunger pumps.
3. Improve the fastening fit: Installed between the nut or bolt head and the connecting piece, it, together with other fasteners, forms a flange fastening structure to meet the assembly requirements of the corresponding connection parts.
4. Suitable for maintenance and replacement: During the disassembly and assembly of the plunger pump, flange inspection and fastener maintenance, the spring gasket can be inspected and replaced based on its actual deformation, damage and elastic state.
Product application
Flange spring washers are mainly used at the flange and related bolt connection positions of plunger pumps, and are used in conjunction with connecting bolts, nuts and other fasteners. Its main application is to assist in maintaining the tight state of threaded connections, and it can be applied to the relevant flanges of the hydraulic end of plunger pumps, pipeline connection flanges, and other tight positions that require the use of corresponding spring washers.
Flange spring gaskets are fastening connection accessories and not flange sealing parts. If there are medium sealing requirements at the flange connection position, corresponding flange seals, sealing gaskets or other sealing components should be configured separately according to the equipment structure.
Scope of application
It can be applied in conjunction with the flange fastening connection positions of plunger pumps, high-pressure pumps and related oil drilling and production equipment, and is suitable for equipment assembly, flange connection, maintenance and repair, as well as fastener replacement. The specific application location and specifications should be determined based on the pump type, flange structure and the size of the matching bolts.
Key points for selection
The core selection basis for flange spring gaskets is the matching fasteners, rather than choosing solely based on the outer diameter of the flange. When purchasing or replacing, the following information should be confirmed with emphasis:
1. Plunger pump model and flange installation position;
2. The nominal diameter of the matching bolts or studs;
3. Inner diameter, outer diameter and thickness of the spring pad;
4. Spring pad structure form and original accessory specifications;
5. Matching nuts and fastening structures;
6. Original part number, physical sample or technical drawing (if any).
Installation and Inspection
Before installation, it is necessary to check whether the specifications of the spring gasket are consistent with the matching bolts, and at the same time, check whether there is any damage to the bolts, nuts, threads and flange connection positions. Spring pads and related fasteners should be installed in accordance with the equipment assembly requirements, and the flange connection should be completed in the prescribed fastening method.
During the equipment maintenance process, it is necessary to check whether the flange connection bolts are loose, and at the same time observe whether the spring gasket shows obvious flattening, cracking, corrosion, abnormal deformation or other damage. Spring pads that have lost their normal elastic state or have obvious damage should not be reused. They should be replaced according to the original specifications.
Before disassembling or assembling the flange or maintaining the fasteners of the high-pressure part of the plunger pump, safety measures such as shutdown and pressure relief should be completed in accordance with the equipment operation procedures. Only after confirming that the equipment is in a state that allows maintenance can the operation be carried out.
