How to select hydraulic oil for electric forklift?
No matter what kind of forklift, it needs lubricating oil. The lubricating oil used by electric forklift includes hydraulic oil, gear oil and grease. Don't think that lubricating oil is only a tool for the maintenance of electric forklift. It is optional. In fact, it is very important for electric forklift. Next, the electric forklift manufacturer will introduce to you what hydraulic oil is and how to select and use hydraulic oil.
The normal operation of electric forklift depends on the hydraulic transmission system. The hydraulic oil is crucial to ensure the normal operation of the hydraulic transmission system and maintain the quality of the hydraulic transmission system. The grading method of hydraulic oil is to use the middle value of 40 ° C kinematic viscosity as viscosity grade, which is divided into 8 viscosity grades: 10, 15, 22, 32, 46, 68, 100 and 150. When selecting hydraulic oil, the system pressure and operating temperature should be considered, and the viscosity should not be too high or too low. The electric forklift manufacturer told us that electric forklift generally uses 46 or 68 hydraulic oil. The specific choice depends on the minimum viscosity without increasing the wear of gear pump and hydraulic valve and the minimum starting viscosity when the electric forklift is parked for a long time.
What should we pay attention to when using hydraulic oil for electric forklift? During the use of hydraulic oil, it is necessary to ensure that the hydraulic oil is clean and prevent impurities, moisture, etc. from entering. The hydraulic oil should be replaced regularly. Because the hydraulic oil will age and deteriorate over time. The way to judge whether the hydraulic oil is deteriorated is to see whether it has peculiar smell, blackening and turbid deposits. Make sure that different brands of hydraulic oil cannot be mixed. The temperature of hydraulic oil should not be too high. If the temperature exceeds the normal temperature, find out the reason. In addition, the electric forklift manufacturer reminds everyone that the cleanliness of hydraulic oil should be kept at NAS6-8 level to ensure that the hydraulic transmission system will not be damaged.
I believe you now understand how to select hydraulic oil for electric forklift and what points should be paid attention to when using hydraulic oil. If you still have difficulties in choosing, you can consult the electric forklift manufacturer. After purchasing hydraulic oil, it must be standardized, otherwise it will backfire and cause irreversible damage to the electric forklift.

New energy forklift power system controllerIn the electric forklift power unit, when the forward contactor is closed, the motor is in a forward rotation state; Whereas, when the reverse contactor is closed, the motor is reversed. By changing the direction of the armature current or excitation current, or by changing the polarity of the excitation winding, the commutation control of the motor is realized. However, the use of two sets of excitation windings with opposite windings will lead to a complex structure and an increase in the volume of the motor, so the first two methods are more commonly used in practicalDo you like ?0

Electric forklifts vs. internal combustion forkliftsHowever, there are also some drawbacks to internal combustion forklifts. First of all, diesel engines are more expensive to run, especially against the backdrop of the current surge in oil prices. Secondly, the internal combustion forklift is noisy and vibrate, and the operating noise of the diesel engine has an irreversible impact on the human body. In addition, the exhaust gas pollution is serious, even if the processor is installed, it will cause environmental pollution, and it is necessary to clean up the dust regularly, which is more cumbersome to maintain, and can easily lead to oil pollution problems on the site.Do you like ?0
