[Asia Fluid Network News] mine submersible pump is to send liquid or liquid pressurized machinery. All equipment in operation, more or less the inevitable failure and damage, resulting in normal pumping. What is needed is that there should be a corresponding treatment in the event of a malfunction. The following is a list of troubleshooting and troubleshooting methods for several common mining submersible pumps. Mining submersible pump failure analysis and solutions (Asia Fluid Network) 1, mining submersible pump can not start: Failure Analysis: First of all, you should first check the power supply meets the requirements; Check the connector connection is broken; To determine the switch contact is tight; Fuse Whether it is blown, whether the three-phase power supply is equal, and whether it is a mechanical fault of the pump itself. Troubleshooting: relax the filler, clear the diversion trough; open the pump body to remove debris, rust; remove the pump shaft to correct or replace the new pump shaft. 2, mining submersible pump suction on the water: Failure Analysis: There may be due to the pump body air or inlet gas, or at the end of the valve is not strict filling water dissatisfaction, vacuum pump packing serious leaks, gate or gate closed lax . Troubleshooting: First water pressure, then the pump filled with water, and then boot; check the check valve is tight, piping, fittings leaks; check the pump shaft seal ring, such as serious wear and tear should be replaced New item. 3, mining submersible pump flow is insufficient: Failure Analysis: power speed is not complete or belt slippage, the speed is low; axial pump blade mounting angle is too small; insufficient head, the pipe is too long or the pipe has a right-angle bend. Troubleshooting: restore the rated speed, remove the belt grease, adjust the belt tightness; adjust the blade angle, reduce the pump installation position, shorten the pipe or change the pipe curvature; seal the pump leak, compaction packing; clearance Plug, replace the impeller; replace the leak ring, plug the leak. 4, mining submersible pump violent vibration: Failure Analysis: May be uneven rotor, or coupling poor, bearing wear and tear may also be rotating parts loose, rupture; may be due to the pipe stent is not strong and so on. Troubleshooting: Can be taken to adjust, repair, reinforcement, straightening, replacement and other methods to deal with. When mine submersible pump found fault, we must promptly identify the problem, correct troubleshooting. Diving work, mainly mechanical and electrical integration of new drainage equipment, by the water-filled high-pressure diving motor and multi-stage centrifugal pump into one, dive into the water run. Low requirements for the installation of environmental conditions, Li and dual, can be placed in a suitable place for drainage under local conditions. Analysis and resolution of its failure can not only improve the competitiveness of products, but also can improve work efficiency.

Hexagon Flange Head Drilling Screw With Tapping Screw Thread
Hex flange self-drilling screw into sheet metal - with a drill - the advantage is the use without the need for pre-drilling and minimal risk of sheet deformation. Suitable for joining sheets where high joint strength is required.
A Hexagon Flange Head Drilling Screw with Tapping Screw Thread is a type of screw that features a hexagonal flange head and a tapping screw thread.
The hexagonal flange head refers to the shape of the screw head, which has six sides in the form of a hexagon. This design allows for easy gripping and tightening using a wrench or a socket.
The drilling screw thread is a type of thread that is designed to create its own hole as it is screwed into a material. This eliminates the need for pre-drilling a hole before inserting the screw.
The tapping screw thread refers to the type of thread that is designed to cut into the material it is screwed into, creating its own threads. This allows for a secure and tight fit between the screw and the material.
Overall, the Hexagon Flange Head Drilling Screw with Tapping Screw Thread is a versatile and efficient screw that combines the benefits of a flange head for easy installation and a drilling and tapping thread for creating its own hole and threads.
