How to maintain and maintain the trolley wire:
In order to ensure the normal operation of the trolley line and prolong its service life, after the trolley line is put into operation, it should be regularly inspected. Today, we are talking about how to maintain and maintain the trolley wire line.
1. Current collectors: Check at least once every quarter. Check the fasteners for looseness, displacement and wear of plastic parts and moving parts, check the spring tension (the contact pressure between the collector brushes and the guide rails should maintain a certain pressure (see the table below). Find problems and deal with them in time.
2. Connector: Check it at least once a year. Focus on checking whether the fastening bolts, welds, and supports are loose, rusted, or displaced. If any problems are found, handle them in time.
3. Brush: Check once every 1-3 months according to the use of mobile electrical equipment. Focus on checking the wear of the collector brush. If the wear amount is 5mm, it must be replaced. If the brush is found to be loose or if the wear deflection occurs during the inspection, the cause should be ascertained and dealt with promptly.
4. Daily inspection: Check whether the straightness of the track has obvious deviation (greater than 20mm), misalignment, whether the insulation protection parts are detached, broken or damaged, whether the stainless steel “v” groove is tilted, and whether there is any foreign matter on the track. And conductive dust and so on. If necessary, check whether the insulation resistance meets the requirements (interphase insulation resistance should be ≥ 5MΩ). In particular, it is necessary to strengthen day-to-day inspections and maintenance for vehicles with large deviations in track alignment, track distance, and inclination, frequent use, excessive dust in workshops, high temperatures, and water, acid, alkali, fog, and outdoor use environments.

Rotary Tablet Press

Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.

The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.

Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.

With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
