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, high-speed circuits, and speed switching circuits.

When using hydraulic elevators, the main causes of noise are mechanical mechanism failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.

Shuangluan.The above are common situations, and there are many other reasons based on the actual situation. Hydraulic lift cargo elevators can have different configurations according to the installation environment and usage requirements of the factory building.

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.

.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.

Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.

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.

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.

There is a possibility of hydraulic system leakage. Check the hydraulic system for leaks, with a focus on checking the hydraulic pipes and joints,ShuangluanLarge hydraulic lifting platform, oil cylinders, and hydraulic valve connections. If hydraulic oil leaks, replace them with composite pads or disturb unprocessed raw materials.

The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms,ShuangluanCustomized hydraulic lifting platform, 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.

This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.

The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance cleaning, and replace the cleaning hydraulic oil to clean.

. 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,ShuangluanSmall hydraulic lifting platform, 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, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.

Online consultation.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.

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.

When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the greater the shaking

Shuangluan.The installation personnel should confirm and count the equipment details, confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.

The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.

Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
