HaodaHydraulicBefore installation the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
Haoda.There are two installation methods for hydraulic freight elevator oil cylinders: jacking and lifting. The difference between jacking and lifting is that the placement direction of the oil cylinder is opposite, which is a qualitative problem and easy to arrange. The disadvantage is that the effective use of the oil cylinder can lift the same load, and the oil cylinder of the lifting mechanism is much larger than that of the lifting mechanism.

Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise, it will affect the use of the guide rail hydraulic lifting platform. When refueling, the hydraulic oil should be filtered and filled, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
.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.
Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder,HaodaHydraulic lifting platform fixed hydraulic, it is recommended to replace it with a new one.
This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.
Safety advantages: Hydraulic elevators are equipped with the safety devices of traditional traction elevators: overflow valve: it can prevent system pressure from being too high when going up; Emergency manual valve: In case of power failure, it can cause the car to emergency descend to the nearest floor position, causing the car to emergency descend to the nearest floor position, and causing the emergency in the car to descend to the nearest floor position; Pipeline rupture valve: When the hydraulic system's pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descending; Oil temperature protection of oil tanks: When the oil temperature of the oil tank exceeds the standard setting value, the oil temperature protection device sends a signal to stop the use of the elevator and wait for the oil temperature to decrease before starting the elevator.

The 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, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.
Honesty and mutual benefit.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.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.
When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, and hydraulic installation after repairing the hydraulic system,HaodaHydraulic aluminum alloy lifting platform, which can easily cause vibration and generate significant noise.
Lets see.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.
In on-site hydraulic elevators,HaodaCustomization of hydraulic lifting platform, it is difficult to detect the rising position, middle position, impact noise, seriously affecting production efficiency. The unstable hydraulic lifting requires an analysis of the hydraulic oil flow rate. Hydraulic pressing oil has poor quality and contains a large amount of impurities, which can also prevent slow and unstable lifting. In addition there are other reasons: lifting the composition of the hydraulic ring. Oil pump, safety valve, directional valve, directional valve, one-way throttle valve (without throttling), and lifting cylinder.
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, stable operation, and simple maintenance compared to the scissor fork type elevator.
Haoda. Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
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.
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, rotary table, tipping, telescoping), 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.
