The quality of jointless lines can be based on the following scale constants:
1, the use of carbon brush life - is consumables, travel interval affect the equipment cycle.
2, no seam line contact shell quality - thickness, hardness, practical temperature, and so on.
3, the collector function - mainly from the use of wheel life, the design of the steering wheel and the collector is satisfied with the use of all types.
4. The problem of expansion without joints and lines - The problem of expansion should be considered when the length exceeds 100 meters.
5, voltage drop problem - according to the various types of copper strip length voltage differences.
Seamless seam line features:
1. Seamless joints are installed without joints, saving time and space.
2. There are few parts without seams, and the track is carded into the device for easy installation.
3, no seam line conductor is electrolytic copper, good conductivity, pure quality, color are bright.
4, the conductor copper and plastic fusion contact, not due to vibration and poor contact.
5, no joints slippery wire without connector, the voltage drop is small.
6. The seamless line is made of special materials, running smoothly, with high speed and low noise.
7. The collector arm length of the jointless and smooth contact line is equipped with independent extension springs and the activity is flexible.
8. The installation of no-slip contact line has a small bending radius and a minimum bending radius of 750mm.
9. The non-seamless slide wire shell is made of PVC-SG-5 insulator, which is resistant to impact and UV rays. It is made of a special formula with good physical properties.
The connection and maintenance of the seamless line is extended to maintain the normal operation of the trolley line. After the trolley line is put into operation, the line is serviced and repaired on schedule.
(1) Brushes: Every 1-3 months should be checked according to the operating environment of the equipment. Focus on reflection brush wear environment, if the amount of wear ≥ 5mm, must be exchanged. When the brush is found to be introspective, if it is found that the brush is loose or there is a wear deflection, the cause should be ascertained and disposed of in real time.
(2) Current collectors: At least one review per quarter. Focus on reflective fasteners for looseness, displacement and wear of plastic parts and moving parts, introspection of spring tension (current collector brush and guide rail squeezing pressure should adhere to a certain pressure. Find problems in real time disposal.
(3) Adaptors: Introspect at least once a year. Focus on whether the fastening bolts, welds, and supporting parts are loose, rusted, or displaced. If any problems are found, dispose of them in real time.
(4) Daily Introspection: Focus on whether the straightness of the track has significant errors (larger than 20mm), misalignment, whether the insulation is detached, fractured, destroyed, and whether the stainless steel “v†groove is tilted; No foreign matter and conductive dust. When necessary, it should be tested whether the insulation resistance meets the requirements (interphase insulation resistance should be ≥ 5MΩ). Extraordinary errors such as coincidence of roadway track, track gauge, skewness, etc., frequent use, frequent workshop dust, high temperature, and water, acid, alkali, fog, and outdoor use, must enhance daily introspection.
