KetaiVehicle mounted hydraulic lifting platformCommon methods of fault diagnosis

Remember not to overload,KetaiHydraulic cylinder lifting platform, overload is the root cause of many faults.

Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.

Ketai.Check valve leakage, oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.

New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.

.After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.

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

Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.

The vibration range is proportional to the lifting height. The higher the height, the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds 10 meters the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.

The hook or rope of the seat belt should be hung on a sturdy and sturdy component or a steel wire rope specifically designed for hanging the seat belt. Prohibit hanging on moving or unstable objects.

Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.

Promise and keep promise.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism electric mechanism,Ketaihydraulic lift, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

The smoothness of the gearbox, gearbox, and hydraulic oil are all carried out according to the requirements in the smoothness table.

After long-term use of the automatic lifting platform equipment, 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.

Management Department.When using hydraulic elevators, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).

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, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.

Ketai.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,KetaiHydraulic mobile lifting platform, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.

The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
