Hydraulic components can be divided into dynamic components and control elements as well as the implementation of components of the three categories. Despite all hydraulic components , their functional and technical requirements to install their own equipment to use are not the same , respectively, are presented below :
Actuator hydraulic cylinders and hydraulic motors .
1, the hydraulic cylinder
Vehicle fuel tanks, single-acting cylinders, hydraulic cylinders, swing cylinder , single-acting cylinders multistage ( sleeve cylinder ) as well as double Multi-stage fuel tanks and other spring return cylinders .
2 , the hydraulic motor
Hydraulic motors, gear motors, vane motors, piston motors , etc. , that can theoretically pump almost quantitatively as horse Up effect.
3 , low speed high torque hydraulic motors
( 1) Cycloid motor.
( 2 ) the curve of the hydraulic motor , shaft rotation and shell turn of two types .
( 3 ) double disc axial piston motor .
( 4 ) radial piston hydraulic motor.
( 5 ) ball plunger -type low speed high torque hydraulic motors.
( 6 ) the static equilibrium of low speed high torque hydraulic motors low .
First, what is the dynamic components ?
Power refers to a variety of hydraulic components .
1 , gear pumps and pump series (including foreign engagement with the ring ) two structural types .
2 , blade oil pump ( including single -stage pump , variable pump , two-stage pump , double pump ) .
3 , piston pumps, axial piston pump and is divided into radial piston pumps, axial piston pumps quantitative variable pump ( variable
Volume is divided into a variety of manual pump with variable pressure compensated variable servo variables, etc. ) from the structure and into the end face with oil and oily with two valve type with oil , rather radial piston pump with oil type, basically for the valve with oil.
Second, the control elements are there?
Various hydraulic valves are all control components.
A pressure control valve
( 1 ) pressure control valve are: relief valve , solenoid relief valve , unloading relief valve, check valve and relief valve , single decompression Sequence valve and non-return valves and sequential valve.
( 2 ) the scope of the sequence valve is divided into direct control sequence valve , remote control sequence valves , unloading valves , direct operated check valve sequence , remote control Unidirectional sequence valve , balance valve direct control and balancing valves and other seven remote control , as well as pressure relay , and a variety of pressure control valve , in all kinds of hydraulic transmission system, according to different conditions and characteristics of the requirements for the various types of hydraulic system.
2 , directional control valves
Directional control valve includes a check valve , check valve , solenoid valve, solenoid valve, solenoid valve and manual valve As well as a variety of manual rotary valve .
3 , the flow control valve Flow control valves are: throttle , one-way throttle valve, control valve, control valve and a one-way trip one-way trip throttle and throttle Valves, check valves and other travel speed .Third, there are several components to perform
