Saint-Quentin Mobile hydraulic lifting table supplyThree common forms of wear

Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.

Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, 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,Saint-Quentin Scissor type hydraulic lifting platform, 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. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!

Lines of various safety equipment

.When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point you only need to add enough hydraulic oil to run.

If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.

The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.

The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.

There are two reasons for the sinking of the hydraulic cargo elevator table: on the one hand, the hydraulic pressure is flexible, and under high pressure or temperature, the volume will change, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, 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, which can also produce significant noise. If it is a problem of tight sealing 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.

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.

Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.

High quality brand.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, 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.

What technical issues are required for the installation of hydraulic freight elevators? The installation of hydraulic freight elevators is actually quite complex. If you do not understand the equipment pictures designed by the elevator manufacturer and the detailed situation of the hydraulic freight elevator designed by the elevator manufacturer, installation errors may occur, leading to equipment failure of the freight elevator! When installing hydraulic freight elevators, it is necessary to accurately calculate the size of the pit. The guide rail hydraulic freight elevator is a freight elevator composed of chains, guide rail torque tubes, and other components, mainly driven by the chain to assist in the upward and downward telescopic lifting of the freight elevator. The pulleys at the four corners of the countertop should be fixed on the surrounding guide rails. The entire elevator equipment is installed on the wall, and wall mounted installation is chosen to enhance the stability of the freight elevator. Choosing the appropriate wall size also requires careful planning.

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,Saint-Quentin Logistics hydraulic lifting platform, separation of air contained in oil and elimination of foam.

Saint-Quentin .Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements,Saint-Quentin Guide rail hydraulic lifting platform, and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.

For hydraulic cylinders in hydraulic elevators, 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.

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.
