There is a lot of development in various industries now. Many goods need to be transported, and the goods need to be transported when they are packed and loaded on the truck. Some goods are very light, but some are very heavy. We used to carry them manually, but now we use It's an electric forklift! In the process of handling goods, we need to carry out the process of frequency conversion and speed regulation. The speed regulation process can be divided into: throttle speed change, volume speed change, throttle speed change will change the cross-sectional size of the flow control element in the control loop, which can control the flow rate of the components. With effective control, the operating speed of the electric forklift can be adjusted more effectively. Because the adjustment of the movement speed is mainly completed by the change of the flow section, the energy consumption will be damaged to a certain extent.
The volume change of the electric lithium pallet truck will change the displacement of the variable piston pump in the control loop, so that the adjustment process of the components can be carried out. On the one hand, the pump-controlled volume speed change changes the motor speed ratio of the electric forklift, and can also further change the output flow of the hydraulic pump. In addition, the displacement of the hydraulic pump can be changed by using the variable organization, so that the output flow of the hydraulic pump can be changed.
The pump source of the electric forklift is completed by the pressure feedback type variable displacement piston pump. When controlling the motor speed, it can be completed by frequency conversion, which can further complete the volume change. With the continuously changing load operation, it will gradually transform into the working pressure of the electric forklift, which will further improve the work efficiency. According to relevant research data, the working pressure of the electric pallet truck is usually maintained in a balanced position with the feedback pressure.
For electric pallet stacker, it is inevitable that the electric lithium pallet truck will leak oil during use. But in the actual use process, we can use some means to prevent it.
Because of the large contact area of u200bu200bthe oil pan, valve cover, etc., it is not easy to compact them, which will cause oil leakage. The oil seal at the rear of the crankshaft leaks, and the oil will enter the clutch, which will cause serious loss of oil in the electric forklift, and will also cause the clutch disc to slip and burn.
Tighten the nut according to the relevant standards. If the compression force is large, the gasket will leak. If tightened too much. The metal around the screw hole will also protrude, and the thread will also slip and leak oil.
If the oil seal is improperly installed, the journal and the cutting edge of the oil seal will have certain differences. Due to yaw, oil, and long-term use, the rubber will be aged, the sealing lip will be damaged, and the spring will lose its elasticity. The oil seal effect will also be lost, and the corresponding parts of the electric forklift should be corrected and replaced according to the standard.
As electric forklifts are now a very important tool for cargo transportation, AC variable frequency variable speed technology has also been more commonly used in the entire electric forklift industry. In addition, when the cylinder liner, piston, and piston ring are worn to a certain extent, the high-pressure gas in the incineration chamber is forced into the crankcase. Therefore, when this phenomenon occurs, we should carry out a timely replacement process for the worn parts of the electric forklift.
