When the fire
Pump power failure occurs too large, not only a waste of resources, but also affect the work of the fire pump, then why the fire pump power consumption will appear too much trouble? What are the measures to be taken Then you analyze the fire pump power consumption is too large for reasons, and to find the appropriate elimination measures. Fire pump power consumption reasons and eliminate too much 1) the direction of rotation to eliminate the measure: check the direction of rotation. 2) Impeller damage elimination measures: Check the impeller, as required to be replaced. 3) Rotating parts bite Elimination measures: Check the internal wear parts of the gap is normal. 4) Shaft bending elimination measures: Alignment shaft or according to the requirements of the replacement. 5) Too high speed Elimination measures: Check motor winding voltage or steam pressure delivered to the turbine. 6) head below the rated value. Pump too much liquid Elimination measures: consult factory. Install throttle valve, cut impeller. 7) liquid heavier than the expected value Elimination measures: Check the proportion and viscosity. 8) The stuffing box does not have the correct stuffing (insufficient stuffing, incorrect stuffing or running-in, stuffing is too tight). Remedy: Check the stuffing and refill stuffing box. 9) Bearing lubrication is not correct or bearing wear Elimination measures: Check and replace as required. 10) The running clearance between wear rings is not correct Elimination measures: Check the clearance is correct. Replace pump housing and / or impeller wear rings as required. 11) pump casing stress too much Elimination measures: eliminate stress and factory representatives advice. After eliminating the stress, check the alignment.

Traction Wire Rope
The wire rope is a helical wire bundle made of steel wires with mechanical properties and geometric dimensions that meet the requirements. The wire rope is composed of steel wire, rope core and grease. A steel wire rope is a rope that is twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral shape with the core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to break the whole rope suddenly, and reliable work. In 1834, European Olubert invented the world's first steel wire rope (smooth steel wire rope).
Wire ropes can be classified according to the material, surface condition, twisting method and purpose of the wire rope.
Classified by material
1. Carbon steel wire rope is made by twisting high-quality carbon structural steel wire as raw material.
2. Stainless steel wire rope, manufactured and twisted with stainless steel wire as raw material.
