[Asia Pump Network News] ZX series of horizontal self-priming pump is characterized by simple structure, reliable, durable. In the normal case of pumps, generally do not need to often disassemble and maintain. When you find the fault can be excluded at any time. Now to introduce the ZX series of horizontal self-priming pump maintenance and disassembly methods. ZX series of horizontal self-priming pump, ZX series of horizontal self-priming pump maintenance should pay attention to points a. Rolling bearings: When the pump long-term operation, the bearing wear to a certain extent, the need to be replaced. b. Front seal ring, rear seal ring: When the seal ring wear to a certain extent, to be replaced. c. Mechanical seal: mechanical seal in the case of no leakage, the general should not demolition inspection. If there is any serious leakage at the lower end of the bearing body, the mechanical seal should be disassembled. Assembly and disassembly of mechanical seals, you must gently, pay attention to the cleaning with the surface to protect the static ring and moving the mirror ring is strictly prohibited percussion collision. The main reason for the leakage caused by the mechanical seal is the rubbing of the mirror surface. The repair method, you can pay to rub the friction surface to restore the mirror. Another reason for the leakage of a mechanical seal is that the O-ring seal (or cushion) is improperly installed or deformed. At this point you need to adjust or replace the "O" ring for reassembly. Two, ZX series horizontal self-priming pump disassembly sequence a. Remove the motor or prolapse coupling. B. Remove the bearing body assembly, Check the radial clearance between the impeller and the front spigot and check for looseness of the impeller nut. C. Remove the impeller nut, pull out the impeller, check the radial clearance of the impeller and back seal ring. D. Tension the mechanical seal tight Pull out the moving ring part of the mechanical seal, check the fit of the moving and stationary ring end faces and check the sealing condition of the O-ring [or cushion] e. , Pull out the coupling. F. Remove the bearing cover, remove the pump shaft and bearings. G. Installation can be carried out in the reverse order assembly.

Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
