Mingshan10 metWhen the hydraulic lifting platform is working 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
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Mingshan.When the hydraulic cargo elevator needs to work, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, explosion-proof electromagnetic directional valve.
Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, check whether the lowering valve is powered on. If there is no electricity, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.
.Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
Pre install equipment, 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,MingshanElectric hydraulic lifting platform truck, 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.
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.
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use frequently check the connection of each part. If loose, tighten it. When the body is under pressure, 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.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve,MingshanElectric lifting platform Hydraulic lifting platform, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Inspection requirements.Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the
To consider its capacity generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.
High value.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,MingshanManufacturer of scissor lift, and speed switching circuits.
The load of goods and the tonnage of goods transported at once also affect the lifting speed. The optimal value for transporting goods on a lifting platform is speed. If it is too heavy, it will affect the speed. The above is the knowledge about adjusting the lifting speed of hydraulic cargo elevators, excellent quality, and discounted prices
Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
Mingshan.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
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.
Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.
