DresdenCustomiMaterials enter the production line at one end of the factory building, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.
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,DresdenGuide rail hydraulic lifting platform, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.
Dresden.Cleaning and maintenance: When there is oil in the oil tank or when oil is refilled, it is necessary to ensure the cleanliness of the filter tank cover. Clean the oil and funnel or container before use. Never bring dirty things into the system, only clean oil.
Aluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material, which is lightweight and has a more beautiful appearance. The disadvantage is that it has a light load capacity and is only suitable for simple high-altitude maintenance work, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
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.
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.
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,DresdenScissor type hydraulic lifting platform, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.
In addition, the lifting mechanism also needs to be equipped with powerful support frames. Therefore, the selection of lifting mechanism or lifting mechanism for hydraulic freight elevators cannot be generalized, but should be based on the working conditions of the elevator.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, major repairs will be carried out to the mechanical and electrical systems.
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.
New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter noise will be generated.
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.
Encyclopedic knowledge.What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.
Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, priority should be given to the hydraulic oil flow angle.
The undercut length of the weld mm should not exceed 10% of the weld seam and the depth should not exceed 0.4mm.
Dresden.. 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. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found,DresdenDouble fork hydraulic lifting platform, they should be promptly cleaned up.
Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, 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.
