How to select hydraulic oil for electric forklift?
Lubricants are required for both electric forklift and ordinary forklift. Lubricants required for electric forklift include gear oil, hydraulic oil and grease. Before that, the electric forklift manufacturer has introduced in detail what is the gear oil of electric forklift, how to select it, and what precautions should be taken. Today, the electric forklift manufacturer will tell you about the knowledge of hydraulic oil, and see how to select and use hydraulic oil.
Many actions of electric forklift depend on traditional hydraulic system. The hydraulic oil is necessary to ensure the normal operation of the hydraulic transmission system and maintain the quality of the hydraulic transmission system, which is very important. The classification method of hydraulic oil is to use the middle value of 40 ° C kinematic viscosity as the viscosity grade, which is divided into eight viscosity grades: 10, 15, 22, 32, 46, 68, 100 and 150. When selecting hydraulic oil, it should be selected according to the system pressure and operating temperature, and the viscosity should not be too large or too small. The electric forklift manufacturer tells us that, generally speaking, 46 or 68 hydraulic oil is used for electric forklifts. The specific selection 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.
When using the hydraulic oil of the electric forklift, what are the precautions? In the process of using hydraulic oil, it is necessary to ensure that the hydraulic oil is clean and prevent foreign matters, moisture, etc. from mixing. The hydraulic oil should be replaced regularly because it will age and deteriorate over a long period of time. The way to judge whether the hydraulic oil deteriorates is to see whether it stinks, blackens and produces turbid sediment. Also, it should be noted that hydraulic oils of different brands cannot be mixed. The temperature of hydraulic oil cannot be too high. If the temperature exceeds the normal value, the cause must be found in time. Finally, the electric forklift manufacturer reminded everyone that the cleanliness of the hydraulic oil should be kept at NAS6-8 for a long time to ensure that the hydraulic transmission system is not damaged.
The above is how to select the hydraulic oil of the electric forklift and what precautions should be taken when using the hydraulic oil. If you still have difficulties in choosing, you can consult the electric forklift manufacturer. After the hydraulic oil is purchased, it should be used in a standardized way to ensure that the life of the electric forklift will not be damaged.

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
