Stabia CastleH
Stabia CastleMAn 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,Stabia CastleHydraulic cylinder lifting platform, and the device will produce; Buzz&# quo; Noise.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, rust prevention is necessary. Because the part of the hydraulic cylinder needs to extend out of the cylinder during operation, it will naturally be corroded by oxides and acidic gases. This requires us to apply an appropriate amount of grease to protect it from erosion as a weight component. If we change the oil, we must open the box and use it for a long time to prevent the hydraulic cylinder from being used for a long time. In the operation of hydraulic cylinders, the speed should be appropriate and should not exceed 2m/s to extend the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and safety, it is very important to install buffer devices internally to protect the hydraulic cylinder. The greater the pressure of the protective hydraulic cylinder, the heavier the load, and the greater its pressure. A specialized product manufacturing enterprise that integrates research and development, as well as service. A long-term professional elevator manufacturer
The hydraulic oil used in the system has the same brand, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.
.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.
Wholesale manufacturers of hydraulic cargo elevators have found that the market demand for hydraulic cargo elevators is also increasing. More importantly, some cargo loading and unloading work, as well as decoration, hotels, logistics, warehouses, supermarkets, etc., are commonly used in these situations, especially in the decoration industry. I have seen many decoration companies use small hydraulic cargo elevators, which are also specially processed and manufactured, and have some differences from the hydraulic cargo elevators we often see. There are significant differences in structure, lifting speed, and height, and the prices of hydraulic cargo elevators also vary. The hydraulic cargo elevators used in the decoration industry have a low lifting height,Stabia Castle6-meter hydraulic lifting platform, some only 2 meters, and do not require many materials. He mainly promotes people, not goods, and rarely promotes goods, so the load is small, but not inferior to the use of other hydraulic cargo elevators. He is stable, safe, interpretable, and durable enough to make hydraulic cargo elevators a good helper in the decoration industry. The function of hydraulic cargo elevators is gradually improving with our needs, and the properties we require are different. Wholesale manufacturers of hydraulic cargo elevators also manufacture according to our requirements.
Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
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.
What are the requirements for the pit? This type of cargo elevator only needs 15-30 centimeters and does not require too much space. The installation of scissor type hydraulic cargo elevators is different from that of guide rail type hydraulic cargo elevators. The scissor lift cargo elevator has a large load-bearing capacity, and the pit depth needs to be set at around 40-70 centimeters. It can also be designed according to customer on-site needs.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
Quality documents.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
The cylinder head oil seal is too tight or the rod is bent, 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.
Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.
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,Stabia CastleMobile hydraulic lifting platform/lifting platform, the greater the shaking. When using it at a working height of 10 meters if possible, please use safety protection measures
Inspection items.Materials enter the production line at one end of the factory building, under the action of high pressure, the hydraulic system inevitably causes the hydraulic valve to flow back or the sealing components to produce oil. The main reasons for the natural descent of the hydraulic cargo elevator include the following points: replacement of the support valve due to leakage. The lowering valve is damaged or not powered on. Require the lowering valve to be kept clean on a daily basis, and if damaged, replace it with a new hydraulic lowering valve in a timely manner.
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.
Stabia Castle.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, 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.
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, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
