【cause of issue】
1, pump reverse.
2, the pump speed is too low.
3, pump impeller loose or equipped with anti.
4, pump impeller blades wound a lot of debris.
5, the pump shaft tripping or fracture.
6, Yang pipe serious water leaks.
7, pump impeller submerged depth is not enough.
8, the pump installation head exceeds the total head of the pump, or move the water level dropped beyond the allowable range.
9, winter use, the pipe in the frozen water.
【Maintenance Methods】
1, for the type of power machine used by the pump, respectively, to adjust the direction of rotation of the pump.
2, according to pump different forms of power machines, respectively, to increase the speed.
3, the demolition of post-mortem? Blockage tomb ぷ 髯 stabbed? H 绻? Site ⑸? Appreciate strict 窒 螅 蛴 蛴 blocking paper? Goshimizu 虢 蹋 蹋 locust 绻? Site mire? Π to find plugging value 淖 涔 涔 find 笾 匦 Lu? Evil Cang?? ⒆⒁ 艄 艄 Peach Garden Music Awards? / Div>
4, the first stop, take the first method of flushing back to clean winding debris. If you can not rule out trouble or winding debris removal is not complete, then the axial flow pump should be disassembled and overhauled to clean the entangled debris on the impeller blades.
5, after dismantling repair. If the pump shaft is tripped, the pump shaft should be reinstalled in accordance with the assembly process requirements of the axial flow pump; if the pump shaft breaks, repair or replace the pump shaft.
6, identify the axial leakage pump concrete pump leaks, respectively, depending on the circumstances were repaired or replaced.
7, appropriate to reduce the installation of the pump height, and re-install the pump.
8, appropriate to increase the pump speed, increase the impeller series, or replace the larger power matching power machine.
9, first clear the pump pipe in the icing, and then boot.

Wire Rope

Tower Crane wire rope is usually used on the tower crane hoisting mechanism, trolleying (luffing) mechanism and slewing mechanism. BQ could provide all models of Wire Rope for Tower Crane. The diameter of tower crane steel wire rope could be 12mm, 14mm, 16mm, 18mm, 20mm, 22mm. 16mm Wire Rope could be used for 12-14 ton Tower Crane. 18mm Steel Wire Rope could be used for 16ton tower crane. Tower crane wire rope could be galvanized wire rope, Non-Rotating Wire Rope, bright wire rope, stainless steel wire rope. Wire Rope Wedge is used for fixing or connecting the wire rope of tower crane.


Wire rope is an essential component of tower cranes as it provides the necessary strength and flexibility to lift heavy loads. Tower cranes typically use high-strength steel wire ropes that are specifically designed for heavy-duty lifting applications.

The wire rope used in tower cranes is typically made up of multiple strands of steel wires twisted together to form a strong and durable rope. The number of strands and wires in the rope can vary depending on the specific requirements of the crane.

Tower crane wire ropes are designed to withstand high loads and provide excellent resistance to abrasion, fatigue, and corrosion. They are also engineered to have a high breaking strength to ensure safety during lifting operations.

Regular inspection and maintenance of the wire rope is crucial to ensure its safe and efficient operation. This includes checking for signs of wear, corrosion, or damage, as well as lubricating the rope to reduce friction and prolong its lifespan.

Overall, wire rope is a critical component of tower cranes, providing the necessary strength and reliability to handle heavy lifting tasks in construction and other industries.
