With the advancement of technology, the modern Counterbalanced Forklift generally adopts the machine-electric-liquid integrated control mode. When we eliminate some faults, we solve most of the Counterbalanced Forklift engine-hydraulic pump-distribution valve-internal load matching problem. . Generally, in the Counterbalanced Forklift operation, these aspects cannot be matched. It is often expressed as: Counterbalanced Forklift's engine speed drops, the working speed is slow, and the excavation is weak.
If it is a Counterbalanced Forklift that has been used for many years, the speed is gradually slower, which is caused by normal wear and tear. The main factors of the whole machine wear and tear caused the Counterbalanced Forklift engine power to drop and the hydraulic system to leak, so that a series of faults are manifested. Due to the internal energy consumption caused by the leakage, a large amount of heat energy is generated, so that the whole system is rapidly warmed up, hydraulic oil and Counterbalanced Forklift's engine oil viscosity drops, causing the entire system to produce high temperatures, which means that the cooler is slightly hotter and slower. This requires a full-machine overhaul to repair and replace worn-out parts. If the new Counterbalanced Forklift suddenly slows down, it is necessary to check the following aspects: Check whether the circuit fuse is open or shorted; whether the pilot pressure is normal; whether the servo control valve-servo piston is stuck; the distributor confluence Failure, etc.; other possibilities are eliminated, and finally the hydraulic pump is dismantled.
