Thread seals generally have two forms on chemical pumps

Troubleshoot Submersible Borehole Pumps Manufacturers components or assemblies in time; avoid mechanical overspeed and overload operation to prevent the oil seal lip temperature from rising, rubber aging, and early lip wear.

 Always check the oil level of the engine oil. If there are too many impurities in the engine oil, and there are alloy powders and metal iron filings, the engine oil must be completely replaced. The brand and quality of the oil to be changed must meet the seasonal requirements.

It is recommended to add Metre Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that can form a thin film of inert material on the components, which can slow down the leakage of the oil seal and extend the use of the oil seal gear Life, can also reduce the noise of the gearbox, the use of this kind of super seal lubricant will not pollute or deteriorate the oil.

4 thread seal

Thread seals generally have two forms on chemical pumps, one is threaded connection gasket seal, the other is threaded and filled seal, both of which are used for small diameter threaded connections. The seal that connects the screw with the electric diaphragm pump to the gasket is the gasket, and the screw only serves to provide the pressing force.

Thread seals generally have two forms on chemical pumps, one is threaded connection gasket seal, the other is threaded and filled seal, both of which are used for small diameter threaded connections. The sealing element of the threaded connection gasket is the gasket, and the thread only serves to provide the pressing force.

In addition to the sealing effect of the gasket itself, the roughness of the sealing surface and the relative geometric position accuracy with the threaded hole also have a great influence on the sealing effect. Because the sealing gasket not only bears the pressing force when tightening the thread, but also bears the torque, which causes the gasket to deform or even damage. Therefore, when the gasket is non-metallic, it is generally only suitable for chemical pumps with low pressure. If the sheet is metal, the applicable pressure can reach more than 30Mpa.

The thread plug that is often used on chemical pumps is another form of thread sealing.

Due to the economic efficiency of plug manufacturing, generally the thread fitting alone cannot play a sealing role, and raw tape, sealant and other fillers are often used to fill the thread sealing gap. Its pressure-bearing capacity depends on the manufacturing precision and material of the thread, and has nothing to do with the fitting form of the plug and threaded hole. Whether the threaded hole and the plug use "cone to cone" or "column to cone", the sealing effect is the same, but the area of ​​use is different.
