Zanstad15 meter hydraulic lifting platformThere are several types of how to choose

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

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.

Zanstad.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, mainly used for heavy types of goods. However, during use, 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?

Separate: Loading and unloading on different platforms.

.When disassembling and adjusting the reverse organization of the equipment, and its meshing surface is not less than 70%. The meshing gap should be appropriate.

Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.

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.

Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.

Due to the formation of a flow closed-loop, the volumetric speed regulation hydraulic elevator has good performance and high load stiffness. The hydraulic system using the volumetric speed regulation scheme has a higher efficiency and greater energy loss compared to the throttling scheme, as its output power is roughly equal to the power required for the elevator to move up. But using an elevator volume speed control system can only reduce the energy consumption during the upward process of the elevator. When the elevator goes down, the oil in the cylinder moves down the throttle valve under pressure, which will cause the temperature of the hydraulic system to rise. Not to mention anything else, just an intelligent alarm is enough to demonstrate the true value of hydraulic elevators.

An inverter can also generate high noise. When the power supply voltage is lower than 85% of the rated voltage, the short circuit ring of the iron core of the device breaks, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.

Executive standard.The hydraulic oil used in the system has the same brand and the oil temperature is between 45~80 ℃. 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.

Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.

The installation personnel should confirm and count the equipment details confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.

Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.

Hydraulic elevators have two working periods and two end dwell times within a working cycle. Working hours refer to the period of lifting and falling objects. The suspension period refers to the period during which the machine temporarily stops working at the required height of rest. Therefore,ZanstadSelf hydraulic lifting platform, each working period is divided into three different stages: starting, constant speed lifting, it is inevitable that some malfunctions will occur. In order not to affect work it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.

Zanstad.Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.

There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight,Zanstad15 meter hydraulic lifting platform, which can also produce significant noise. If it is a problem of tight sealing,ZanstadSmall hydraulic lifting platform, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.

There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
