2T Electric Forklift Oil Pump Motor: Understanding Its Role in the Hydraulic System

Electric forklifts are used on a large scale in warehouses, factories, and logistics facilities. Apart from the traction motor that powers the vehicle, the hydraulic system has an additional significant energy source—the 2T Electric Forklift Oil Pump Motor.

For an average electric forklift weighing 2 tons, the oil pump motor powers the hydraulic pump that delivers the energy for lifting, tilting, and other hydraulic functions performed by the forklift. The performance of the pump motor has a direct influence on the lifting responsiveness of the forklift, its energy efficiency, and the reliability of the equipment in general.

How Does the Oil Pump Motor Function?

The working principle of the oil pump motor is the conversion of the electrical power from the battery of the forklift into mechanical power that drives the hydraulic pump. The pump generates hydraulic flow and pressure to perform different lifting operations.

When lifting a heavy load, the hydraulic pressure increases, and, thus, the motor must generate a certain amount of torque to provide stable operation of the pump. Therefore, sharp turns in the operation of the motor, torque of the motor, characteristics of the pump, and hydraulic requirements should be considered as a whole.

Motor and Hydraulic Operations

A 2-ton electric forklift deals with non-stationary loads. With the increase of the hydraulic load, the resistance that the pump operates against increases as well.

An appropriately selected Electric Forklift Oil Pump Motor has to maintain stable torque then. The good cooperation between the electric motor and the hydraulic pump enables to carry out the lifting process smoothly.

Thus, the selection of the motor must take into consideration hydraulic pressure, pump displacement, required flow, speed of the motor, voltage, and the load of the forklift.

Frequent Use and Cooling

Forklift hydraulic systems usually operate in the start-stop mode during loading and unloading of materials. All the lifting cycles create a lot of heat in the motor that can lead to various issues, especially when handling materials in high-intensity working conditions.

Excessive heating of the motor can lead to insulation, bearing, and problems in the long-term operation of the motor. So, while selecting the pump motor the type of construction of the pump, the cooling conditions, the frequency of lifting, and many other factors should be taken into consideration.

Efficiency and Matching

As electric forklifts work with electric batteries, the efficiency of the hydraulic system influences the working time of the equipment between the charges.

An efficient oil pump motor makes it possible to avoid wasting electricity while at the same time providing required hydraulic power. It is also necessary to match motor and controller properly in order to receive stable torque and speed of the working process.

Improper coordination can result in too high electric current, poor response from the hydraulic system, and excessive temperature. Hence, the necessity to confirm mechanical dimensions and electrical requirements in advance during replacement operations.
