KarlsruheHydraWhen the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Karlsruhe.When using a crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the crane.
When encountering signs of overheating in the electric motor, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
.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, and replace it if necessary.
New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case,KarlsruheCylinder mounted hydraulic lifting platform, if the legs lack butter, noise will be generated.
A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, 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,Karlsruhe10 meter hydraulic lifting platform, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
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, it is also prone to problems. When the speed of the hydraulic lifting table slows down it should be suitable for the operating power.
The hydraulic pump also has an impact on the flow rate of hydraulic oil. If the hydraulic pump is used for a long time, it is necessary to check whether the oil supply of the hydraulic pump is firm and firm.
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, which can easily cause vibration and generate significant noise.
Supply chain quality management.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, pits, paint leakage, and sagging.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
Before installation,Karlsruhe3-meter hydraulic lifting platform, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective replace it with a new valve.
packing.After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
When working on scaffolding without scaffolding or without railings, if the height exceeds 5 meters, safety belts must be used or other reliable safety measures must be taken.
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.
Karlsruhe.The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
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, 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.
