FAQ

What are the parts of the hydraulic station

The hydraulic station is composed of pump unit, integrated block or valve assembly, fuel tank and electric box. The pump device, which is equipped with motor and oil pumps, is the power source of the hydraulic station, which converts mechanical energy into the power of hydraulic oil. Integrated blocks - are composed of hydraulic valves and channel bodies. It adopts direction, pressure and flow control for hydraulic oil. Valve assembly - the plate type valve is mounted on the platform and the back pipe is connected to the integrated block. The oil tank is a semi-enclosed container of steel plate, which is also equipped with a filter oil net and air filter, which is used for the cooling and filtration of oil storage and oil. Electrical box - two forms: a terminal board that sets the external lead. One is a complete set of control appliances. The motor, gear pump - provides the driving force for the hydraulic system. The flow direction of hydraulic oil flow is controlled by means of the electromagnetic reversing valve, which changes the direction of the oil cylinder. (3) electromagnetic overflow valve, prevent the overpressure in the hydraulic system, the equivalent of the relief valve, protect the safety of the oil system and oil pump and hydraulic system pressure constant.

How does the air in the hydraulic system affect the work of the system?

Hydraulic system with air first will certainly affect the system pressure, the oil will be a bubble, the action of actuators is not stable, have crawl phenomenon, pipeline and equipment vibration, and produces air corrosion and dry friction to hydraulic components, affect the service life of the element.

What are the components of a single hydraulic prop?

A complete individual hydraulic prop, probably by 15, and a total number of about 35 parts, the main components are: cylinder, live column, hand, stigma, roof, base, piston, cylinder pin, connecting wire, reset spring, and accessory parts: note liquid gun, unloading handles, three with valve, etc.

What does the hydraulic system do?

The disadvantages of the hydraulic system are: 1, due to the resistance and leakage of fluid flow, the efficiency is lower. If handled improperly, the leak will not only pollute the site but also cause fires and explosions. Because the performance of the job is subject to temperature change, it is unfavorable to work at very high or very low temperature. The hydraulic components have higher manufacturing accuracy, so the price is more expensive. Due to the leakage of liquid medium and the compressibility effect, strict transmission ratio cannot be obtained. It is not easy to find out the cause when the hydraulic transmission fails. Use and maintenance requirements have high technical level.

What are the rules and instructions on the graphic symbol of hydraulic components in China?

The graphic symbols that are not specified in the standard may be derived according to the principles of this standard and the regularity of the enumerated illustrations; When cannot reference and derived directly, or it is necessary to specify one of the important components in the system structure and principle of action, all permits the local structure diagram.

The power component of the hydraulic system, the control component, and the execution component

In hydraulic transmission system, the power element is hydraulic pump, actuator and hydraulic cylinder. Hydraulic system is mainly composed of: power components (pump), executive components (cylinder or hydraulic motor), control components (valves), auxiliary components and working medium of five parts. Power element (oil pump) : its function is to convert liquid into liquid pressure energy using mechanical energy of the original motive. It's the power part of the hydraulic drive.

Who knows what the hydraulic component is?

That means you can adjust it manually, the last one is a silencer, you know, you know it's a manual adjustment, except for this one

Principle of hydraulic pump of hydraulic pump

A hydraulic component that provides a pressurized liquid for hydraulic transmission, a type of pump. Its function is to transform the mechanical energy of the engine (such as motor and internal combustion engine) into liquid pressure. Many factors affect the service life of the hydraulic pump, in addition to pump their own design and manufacture factors and some related to the pump use components (such as coupling, filter, etc.) in the process of selection, commissioning operation of operation, etc. Also have relations. The hydraulic pump works by moving the volume of the pump chamber, which compresses the fluid and makes the fluid pressure energy. The necessary condition is that the pump chamber has a seal volume change. Hydraulic pump is the power of the hydraulic system components, which is driven by the engine or motor, suction pressure oil from the hydraulic oil tank, formation pressure oil discharge, a components to the implementation of the components. Hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump. Common type of hydraulic pump:
