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.
When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
Liaoning.Many operating factories often require the use of hydraulic cargo elevators, which can be lifted and lowered, making it very convenient to use. Many people do not know the knowledge of hydraulic cargo elevator lifting and adjustment. If they understand this knowledge, it will be helpful for future maintenance. The power unit of the fixed chain elevator for hydraulic lifting of cargo elevators drives the hydraulic oil to generate pressure, causing the oil cylinder to move back and forth to drive the lifting platform, is composed of the power unit and the oil cylinder. The power unit is manufactured with four outlet holes, which can be adjusted in size to increase or decrease the hydraulic oil flow rate of the oil cylinder, Adjustable motor speed or electro-hydraulic proportional valve to adjust hydraulic oil flow rate; The longer the oil pipe and hydraulic oil pipe,LiaoningMovable hydraulic lifting platform, the longer the rise time. So during installation, try to minimize the length of the pipeline within the allowable range of the design; On the basis of adjusting the power device, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.
The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement, stable lifting, and easy operation, and are mainly used in factories, government agencies, commercial stores, and the construction and decoration industry.
.Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.
The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank,LiaoningHydraulic lifting platform Electric lifting platform, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators curved arm elevators, car mounted elevators,Liaoning20 meter hydraulic lift, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
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.
Many high-rise cargo transportation often requires the use of hydraulic cargo elevators or transport elevators, but in practical applications, there is a strange phenomenon that more people choose to use hydraulic cargo elevators than elevators. Why is this? We are a long-term elevator manufacturer that welcomes inquiries

Where is it.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.
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
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.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
Promise and keep promise.The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times, each load-bearing component must not have deformation or cracks.
The so-called input hydraulic energy refers to the input flow rate and pressure, and the output machinery is the speed and traction force during linear motion. All these parameters are achieved through changes in working volume, so hydraulic cylinders are a type of volumetric actuator. In order to meet the different needs of various machinery, hydraulic cylinders have different structures and hydraulic capabilities. According to hydraulic capacity, it can be divided into single acting hydraulic cylinders and double acting hydraulic cylinders. According to its structural characteristics, it can be divided into plunger hydraulic cylinders and hydraulic cylinders. Telescopic hydraulic cylinders and hydraulic cylinders are both referred to as the heart of hydraulic cargo elevators. How to maintain the heart of a hydraulic cargo elevator? Professional elevator manufacturers guarantee quality service, and quality. Your satisfaction is our pursuit! Welcome to inquire by phone
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.

The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.
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, hotels logistics, warehouses, supermarkets, etc., 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, shape, 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, 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.
