OsnablukHydrauMotor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
Osnabluk.Hydraulic cargo elevator sinking refers to the lifting of the cargo elevator equipment to a designated position, and after a period of time the entire table surface will automatically descend by a certain distance under its own weight. The phenomenon of hydraulic cargo elevators naturally descending during the leveling process. such
Therefore, 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.
.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.
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.
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.
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,OsnablukHydraulic fixed lifting platform, 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.
Compare the measurement curves and then go to the variable displacement pump or variable speed motor. Long term targeting all types of high-priced elevator manufacturers nationwide with reasonable prices and comprehensive services, we have gained recognition from our customers
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
Affordable price.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, and there should be no wrinkles, pits, paint leakage, and sagging.
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,OsnablukAutomatic hydraulic lifting platform, and replace it if necessary.
Test conclusion.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.
This product has a solid structure, smooth lifting, easy installation and maintenance, and is an ideal cargo transportation equipment for replacing elevators on lower floors.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
Osnabluk.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 encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
Hydraulic cargo elevators have been used in some high-altitude operations in recent years,OsnablukHydraulic lifting platform Electric lifting platform, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
