imaginary cleaned or replaced regularly

  In the system for disassembly cleaning and replacement filters can effectively remove from the hydraulic fluid solid particles, which is one of the key measures of pollution control. Fluid passing through a good filter to prevent swarf or other large particles stuck causing elements, scratches, clogging and other faults. On the pump inlet, an important component of the inlet filter pump is installed, etc. imaginary cleaned or replaced regularly.
     3. Ensure cleanliness of hydraulic oil indicators
     Hand Pallet Truck crane used hydraulic oil should generally be maintained volume, viscosity, total acid as the main test indicators.
     Maintenance, adding crane hydraulic oil hydraulic system shall comply ZBE39002-86 "car tire from the attention and solid particles crane hydraulic oil contamination level" standard, namely: Group particulate contamination level should not exceed 18/ls, cranes used in the process hydraulic oil should not exceed 20/16; moisture limit indicators: total water content of hydraulic oil required should not exceed o. 1%; operating viscosity limit indicators; requirements kinematic viscosity hydraulic oil change should not exceed 10% of the soil; total acid number limit: Requires total acid number should not exceed o. 3m8 (KoH) / 8.
     4. Ensure that the closed nature of the hydraulic system
     Hydraulic truck crane hydraulic system to achieve dustproof and waterproof to keep the system closed, prohibited foreign material from entering the hydraulic system
