Electrohydraulic push rod is a kind of machin,electric,hydraulic type flexible driving mechanism,it is with actuators(cylinder),the control mechanism(hydraulic control valve group)and power(oil pump motor)components,according to the site of installation space and the user use the electro_hydraulic push rod can have a variety of strutural forms(see the specific electeic liquid push rod shape demension ,can also be customized according to user requierment style).Motor driven by positive and negative bidirectional hydtaulic pump output pressure oil,the hydraulic control valveto the cylinder ,realizes the reciprocating movement of the piston rod..hydraulic control valve group is mainly composed of an overflow valve,oil valve,check calve,regulating valve(user requirement),a liquid control one_way valve(hydraulic lock)and other components ,can also be based on the electro-hydraulic push rod operating characteristics,design different function circuit combination valve,meet the job requirements.General introduce of self-locking ,bake locking and sliding are self-locking:running speed adjustable speed type,not speedcontrlo;electrl-hydraulic putt working angle with horizontal  push ,push up (including lblique),push down(including several oblique),Electrohydraulic push rod has the following main features;

(1)    hasthe advantages of compact structure ,convenient installation,small occupied space,easy maintenance.

(2)    May be starting with load,with overload protection function;

(3)    Loop provided with bidirectional hydraulic lock,can be stopped at any position within the scope prescribed stroke and self-locking ,and maintain constant output force

(4)    Push pull,speed(stepless adjustable user requirements),driving range.

(5)    Due to power outages,push rod self-locking ,avoid accidents

(6)    Adopts full hydraulic pressure drive,sensitive action,stable running ,which can effectively buffer the external impact force,stroke control precision(0.5mm>).

(7)    For mechanical electrical and hydraulic integration of full closed struture ,working oil circulation in non pressure closed steel tube,has the advantages of small volumn.no oil leakage,in the bad working environment ,no dust,no water ,no corrosion,long service life.
