he amount of pollution from the type of hydraulic system

Contamination of the hydraulic system Scissor lift sail technology classification of sources can generally be divided into the following three types.

The amount of pollution from the type of hydraulic system
     Contamination of the hydraulic system lifting sail technology classification of sources can generally be divided into the following three types. Namely;
     1. Assembly pollutants
     2. Intrusionproblem pollutants
  3. Generates pollutants
   In Hand Pallet Truck truck crane manufacturing, assembly and commissioning process, the hydraulic system is the main pollutant assembly contaminants. Cranes used in the process, pollutants are mainly generated intrusionproblem pollutants and contaminants. These pollutants and mainly solid particles such as iron, sand, ash umbrella, as well as fiber, film, welding slag, dark film, air. In the crane commissioning process, there intrusionproblem contaminants. Hydraulic system during commissioning solid particle size distribution as shown in Table 2-8. Testing method, g an optical microscope or a manual counting method.
