The lifting platform is a multifunctional heavy loading and unloading mechanical equipment which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.Mayday,The hydraulic pump also has an impact on the flow rate of hydraulic oil. If the hydraulic pump is used for a long time, it is also prone to problems. When the speed of the hydraulic lifting table slows down,The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.

Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.One of the executing components of the hydraulic cargo elevator system is the hydraulic cylinder. The hydraulic cylinder is responsible for linear lifting or retraction. Its characteristics are light weight, high power, simple structure, convenient maintenance, low motion inertia, frequent commutation, and convenient remote control. Hydraulic cylinders are widely used in various single acting hydraulic cylinders as an example to analyze the conversion of hydraulic energy into mechanical energy for linear motion.After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.superior quality,New reference wiring diagram . Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft,MaydayElectric hydraulic lifting platform truck, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level , please stop using it; When the lifting height exceeds meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform

Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing,MaydayCylinder mounted hydraulic lifting platform, wood processing, chemical filling etc., to meet the lifting needs of different operation heights, roller, rotary table, steering, tipping, telescoping), and with various ways (separate, linkage, explosion-proof), it has stable and accurate lifting frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.Welcome calls ,The hydraulic oil used in the system has the same brand, and the oil temperature is between ~ ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.The manufacturer of hydraulic cargo elevators tells you the reason for the instability of hydraulic lifting equipment. Hangzhou hydraulic cargo elevator equipment has always had good stability, Hangzhou hydraulic cargo elevators may inevitably encounter some faults during the lifting process, such as very unstable conditions. What is the reason for the instability of the elevator? How to solve these problems?Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.Mayday,Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button,MaydayFixed hydraulic lifting platform, check whether the lowering valve is powered on. If there is no electricity, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
