DenverHydrauliThe 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, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
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,DenverFixed hydraulic lifting platform, and after each cleaning, the system should be drained while the oil is hot. After cleaning, hydraulic cylinders are equivalent to the heart of the hydraulic system maintaining the hydraulic cylinder is an important part of the entire hydraulic system maintenance. In addition, making it difficult to repair heart problems. Therefore, maintenance of hydraulic cylinders should be cautious. Professional elevator manufacturers have advanced technology, strict testing, more affordable prices, and more discounts. Welcome to consult
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.
.Protective device: In case of power or oil circuit failure,DenverLifting platform hydraulic station, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
One of the executing components of the hydraulic cargo elevator system is the hydraulic cylinder. The hydraulic cylinder is responsible for linear lifting or retraction. Its characteristics are light weight, high power, simple structure, convenient maintenance, low motion inertia,DenverHydraulic lifting platform, frequent commutation, and convenient remote control. Hydraulic cylinders are widely used in various single acting hydraulic cylinders as an example to analyze the conversion of hydraulic energy into mechanical energy for linear motion.
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, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
Promise and keep promise.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 combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
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.
Click to view.Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, pipelines and joints.
Personnel engaged in high-altitude operations must be healthy, and those who suffer from mental illness, epilepsy, or have been identified by a doctor as having hypertension, heart disease, or other diseases that are not suitable for high-altitude operations are not allowed to participate in high-altitude operations. When it is found that staff members are drinking alcohol or feeling low spirits, it is prohibited to work at heights.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.
Denver.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.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). 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. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
