????如今在許多廠房倉庫等地都會見到直頂式液壓升降平臺運輸貨物，直頂式液壓升降平臺是屬于液壓升降平臺中一種常見的傳輸設備，可運輸0-50噸的貨物，大大提高了效率，但是有時候運輸貨物速度會變慢，今天就來給大家講解一下出現(xiàn)這一現(xiàn)象的原因。

????1、直頂式液壓升降平臺額定速度和額定載重的提升，都意味著必須增大主機功率，使用更大一號的曳引機。一旦主機功率增大了，變頻器功率也必須增大，相應的接觸器，動力線都必須加大號。

????2、直頂式液壓升降平臺其他配置，比如光電平層開關，強迫減速開關級數(shù)，安全鉗、導軌，導靴之類的可能都因速度引起變化，當然，這個必須與具體制造廠家的配置如何分級相關。

????3、直頂式液壓升降平臺液壓泵站系統(tǒng)的電磁閥可適當調(diào)節(jié)速度，如果已經(jīng)調(diào)節(jié)到最大了，嘗試檢查液壓升降平臺的液壓油是否充足，油缸是否漏油等，如果都沒有問題，速度還是慢，建議更換更大的泵站系統(tǒng)。

????4、直頂式液壓升降平臺應符合中華人民共和國機械行業(yè)標準JB/T9229.1、JB/T9229.2、 JB/T9229.3，液壓升降平臺一般分直頂式液壓升降平臺、剪叉式液壓升降平臺、四柱式液壓升降平臺等。工作環(huán)境溫度-15-+40℃，一般要求工作臺上升速度應為6-9m/min，下降速度應不大于6m/min. 升降臺類型不同計算方式稍有區(qū)別;升降機速度的計算：升降速度等于升降高度/(油缸的體積/泵站排量)。

? ?Nowadays, in many factories, warehouses and other places, straight top hydraulic lifting platforms can be seen transporting goods. Straight top hydraulic lifting platforms are a common transmission equipment in hydraulic lifting platforms, which can transport 0-50 tons of goods, greatly improving efficiency. However, sometimes the speed of transporting goods may slow down. Today, we will explain the reasons for this phenomenon.

? ?1. The increase in rated speed and rated load of the straight top hydraulic lifting platform means that the main engine power must be increased and a larger traction machine must be used. Once the power of the host increases, the power of the frequency converter must also increase, and the corresponding contactors and power lines must be enlarged.

? ?2. Other configurations of the straight top hydraulic lifting platform, such as photoelectric leveling switches, forced deceleration switches, safety clamps, guide rails, guide shoes, etc., may vary due to speed. Of course, this must be related to how the specific manufacturer's configuration is graded.

? ?3. The solenoid valve of the hydraulic pump station system of the straight top hydraulic lifting platform can adjust the speed appropriately. If it has already been adjusted to the maximum, try to check whether the hydraulic oil of the hydraulic lifting platform is sufficient, whether the oil cylinder leaks, etc. If there are no problems and the speed is still slow, it is recommended to replace it with a larger pump station system.

? ?4. The straight top hydraulic lifting platform should comply with the machinery industry standards JB/T9229.1, JB/T9229.2, JB/T9229.3 of the People's Republic of China. Hydraulic lifting platforms are generally divided into straight top hydraulic lifting platforms, scissor type hydraulic lifting platforms, four column hydraulic lifting platforms, etc. The working environment temperature is -15-+40 ℃. Generally, the lifting speed of the workbench should be 6-9m/min, and the descending speed should not exceed 6m/min. The calculation method may vary slightly depending on the type of lifting platform; Calculation of lift speed: The lift speed is equal to the lift height divided by the volume of the oil cylinder divided by the displacement of the pump station.
