the larger the mass of the object the load cannot exceed its rated load. When it is raised to a certain height

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.When the hydraulic lifting platform is working, the greater the shakingZotmir,Usage and instructions for steel wire ropes in elevators: The steel wire ropes of the steel wire ropes require very high strength, usually made of high-quality carbon steel with a carbon content of .% -.%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity, smooth operation, no noise, suitable for high-speed transmission, high strength, strong overload capacity, and reliable operation, it has become a commonly used rope for hydraulic elevators.The smoothness of the gearbox, gearbox,ZotmirHydraulic lifting platform and hydraulic lifting platform, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.CoronellUsers should arrange dedicated personnel to operate hydraulic elevators,ZotmirScissor fork hydraulic lifting platform, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on theThe hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, it should be replaced.When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.

Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, first connect the power supply and press the button to drive the motor of the hydraulic power unit to drive the gear pump. The hydraulic oil forms a certain pressure through the vane pump and passes through the oil filter; Explosion proof electromagnetic directional valve; Throttle valve; Hydraulic control one-way valve; The balance valve enters the lower end of the hydraulic cylinder,ZotmirGuide rail elevator, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, explosion-proof electromagnetic directional valve.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, 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.market,Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, and alignment points, and confirm that the foundation meets the requirements before construction.

Stability: The workbench should evenly withstand % of the MAX load capacity and be stable at the MAX elevation.Honesty and mutual benefit,The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.Surface paint quality: The paint should be smooth and flat, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.Zotmir,There are many reasons for unstable workbench descent, such as overload, unstable support, severe eccentric load, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
