The QHEPM-1000 row steel pipe hoisting electrical permanent magnet lifting spreader control system designed and produced by Hunan Qianhao Electromechanical Technology Development Co., Ltd. has recently passed user acceptance and passed nearly half a month’s trial operation.
The use effect is good. The user gave It is highly rated.
This set of electric permanent magnet lifting spreader system is used in the 168 project team of a well-known large steel pipe manufacturing enterprise in China. The electric permanent magnet imported from Italy has too little suction force and often hangs the pipe phenomenon, and the controller often burns components, so the user Want to carry out the localization transformation, the customer through the preliminary technical exchanges, on-site inspections, business negotiations, and finally decided to implement the transformation by our company.
The relevant technical parameters of the steel pipe are as follows:
Carbon content: 0.15～0.5%
Steel pipe temperature: not more than 60℃.
Outer diameter of steel pipe: Φ32～Φ180mm, wall thickness: 2.5～25mm
Unit weight per meter: 16.6～163.8kg/m
Center distance of tube row: up to 880mm
The technical index of the electric permanent magnet hoisting sling body
Model: QHEPM-1000
Rated voltage: DC170V
Working current: 32A
Excitation and demagnetization time: both less than 1 second
A working cycle: about 15 to 18 seconds
Dimensions: 924 X 312 X 110 (mm)
Using magnetic shielding technology to ensure that there is no magnetic force outside the magnetic poles
Residual magnetic force after demagnetization<50N
Maximum pull-off force: 1000kg; (diameter 168mm, wall thickness of 25mm steel pipe)
Note: The factory inspection has reached more than 1200kg for each unit.
Weight: about 220kg/set
Since QHMAG establishment, our company has always insisted on independent research and development, and attached great importance to personnel training and technological innovation. Continuously satisfying users' higher standards and constantly adapting to market changes are our eternal goals.
