Principle of Mechanical Jack in Use

In the process of using mechanical jacks, we usually want to know what the working principle of hydraulic jacks is. Hydraulic jacks mainly use hydraulic system to do work. Usually mechanical pumps or electric hydraulic pumps are equipped to do hydraulic transmission to explain the basic principles of mechanical jacks for you as follows: mechanical jacks use hydraulic pumps to make mechanical energy of the original motor. The pressure energy transformed into liquid can  transfer energy through the change of mechanical jack energy. Through the transmission of various control valves and pipelines, the liquid pressure energy can be converted into mechanical energy by means of hydraulic actuator (hydraulic cylinder or motor), so as to drive the working mechanism and realize linear reciprocating motion and rotary motion. The liquid in the mechanical jack is called working medium, which is usually mineral oil. We also call it mechanical jack oil. The function of mechanical jack is similar to that of belt, chain and gear in mechanical transmission.

Mechanical jack: Hydraulic pump driven by manpower or electric power, driven by hydraulic system, with cylinder block or piston as lifting parts. Hydraulic jack can be divided into integral type and separate type. The integral pump is connected with the hydraulic cylinder; the separated pump is separated from the hydraulic cylinder and connected with a high-pressure hose in the middle. Hydraulic Jack has compact structure and can lift weights smoothly. It can lift weights up to 1000 tons and travel 1 meter. It has high transmission efficiency, so it is widely used. However, it is easy to leak oil and is not suitable for long-term support of weights. For long-term support, self-locking jacks, screw jacks and hydraulic jacks can be made into multi-stage telescopic jacks to further reduce the profile height or increase the jacking distance. In addition to the basic types mentioned above, hydraulic jacks can be refitted into sliding formwork jacks, hydraulic lifts and tensioners according to the same principle for various special applications,Workplace.

Mechanical jacks are widely used in construction, shipbuilding, metallurgy, mining, petrochemical, Railway Engineering and other industrial jacking, stretching, extrusion and other operations. In recent years, it has been widely used in foundation settlement test and static pressure pile.

Mechanical jacks can be divided into mechanical jacks, electric hydraulic jacks, synchronous hydraulic jacks, bridge jacks, thin hydraulic jacks, ultra-thin mechanical jacks, pile foundation testing hydraulic jacks, large tonnage hydraulic jacks, tensioning hydraulic jacks, hollow hydraulic jacks and so on. Welcome to visit and purchase.

Mechanical Jack small volume hydraulic device, simple operation, easy to use. Handle design conforms to ergonomics principle. Manual oil pump has three main functions: lifting, handling and lowering. Integral casting cylinder, beautiful appearance, durable, high-quality steel plate, chrome-plated piston rod, internal relief valve to provide overload protection, speed control, valve core using integral parts, reduce maintenance costs. It is a good assistant in handling goods in the workshop.
