Difference between hydraulic crimping tools and hydraulic system

Hydraulic components can be divided into Hydraulic Crimping Tools and hydraulic hose crimper, 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 crimping head.

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.
