This machinery is what form an organic whole by small-sized power unit and oil cylinder is electro-hydraulic device. This machinery is what form an organic whole by small-sized power unit and oil cylinder is electro-hydraulic device. Small-sized power plant is form by electromotor, oil pump, a powerful person and gasoline tank: Oil cylinder uses double canister structure, need not vitta and use flange to join means and dynamical unit undertake oil path connects. Through controlling electromotor, changeover and stop, implementation oil cylinder is adjustable reach inactive action. Its appearance is just as two cylinder photograph to fold (see the graph shows) 1 times. Graph 1 tectonic diagram 1 make a plan basically 1 for appearance structure diagram, it by oil cylinder 1, electromotor 2, airframe (pump valve) 3, gasoline tank 4 composition. Electromotor is installed at airframe (main body) a side, this device has hand in, the cent of dc, if use at the mobile apparatus such as car, can choose DC12V or drive of DC24V dc motive, by accumulator group power supply, charge to accumulator group by system of its equipment circuit again. If use at fixed equipment, can choose drive of single-phase AC motor. Because this device installs use position to have bigger aleatoric sex, the corresponding step that lie between oil was taken between reason electromotor and hydraulic pressure component, invade electromotor in order to prevent leak oily fluid. Want to change the direction of rotation of electromotor only, can dominate the adjustable action of oil cylinder. Hydraulic pressure oil pump is used but, go against revolving gear pump, it is installed within airframe body. Hydraulic pressure a powerful person basically employs pressure and directional control a powerful person, if relief valve, fluid accuses one-way a powerful person, overload a powerful person, fluid,accuse reversal valve and hand to move shut-off valve to wait. Because the configuration of oil pump is a basis,dimension of oil cylinder structure and piston lever are extended, retractile rate is firm, so this device need not configure flow control valve, type of join of oil path of type of board of a powerful person all is used between all sorts of component, concentration installs the airframe at this device inside. Gasoline tank installs the other a side at airframe, because used airtight type structure, although the change of aleatoric installation and working place, all won't cause the leak outside oily fluid. Orgnaization of pressurization of heavy weight type was installed inside gasoline tank, in order to makes sure this device is when different installation and working place, oil pump has good oil absorption performance. Oil cylinder oil cylinder is double working style, because use double canister structure, so it does not need to configure vitta and join of group of a powerful person, amid ministry uses flange to join means and airframe connect. 1.

Oil cylinder pursues diagram of loop of 2 hydraulic pressure principle of work of system of 2 hydraulic pressure pursues 2 pursue for principle of hydraulic pressure system, its job principle is as follows: Lever of oil cylinder piston is extended should control electromotor 1 when turning, fluid accuses reversal valve the core of a powerful person of 5 falls in minim pressure oily action, be in what the graph shows 2 times is left, oil pump 2 begin from gasoline tank fluid of 8 inspiratory oil. The pressure oil that comes out from oil pump charges one-way a powerful person through fluid 4 with checked throttling valve the 9 antrum do not have lever that from oil cylinder the oily mouth A of 10 enters oil cylinder, make be extended outside piston lever. The oily liquid that oil cylinder has lever accent the checked throttling valve from other a side of classics of oily mouth B ' charge one-way a powerful person with fluid 4 return oil pump to present oily opening. The oil pump below status of this kind of job has two kinds of ways into oil, it is an oil that oil cylinder has lever accent (it is less than the oil that enters the antrum that do not have lever to measure) , 2 it is from inside gasoline tank complement is not worth a part. Lever of oil cylinder piston is retractile when electromotor when condition of 1 place changeover, oil pump 2 make at the same time go against circumgyrate, fluid accuses reversal valve the core of a powerful person of 3 is in the buy of right side position that the graph shows 2 times. At this moment the fluid of classics giving oil of pump charges one-way a powerful person 4, checked throttling valve 9, oil cylinder the oily mouth of 10 (the antrum having lever that enters oil cylinder, make its piston lever retractile. The oily mouth of the classics that answer oil that right now oil cylinder does not have lever antrum the 4 checked throttling valve with another side ' , fluid charges one-way a powerful person 4 return oil pump to present oily opening, the rest is oily at the same time fluid (because do not have an oil of lever antrum,be more than those who have lever accent to receive oil) classics fluid accuses reversal valve 5 return gasoline tank. Bear maintains when outside extending certain length top to rise when piston lever, carry and stopping to offer oil, fluid charges one-way a powerful person 4 place close position, piston lever carries negative charge the position is secured in some. If piston lever is outer,carry action to fall right now and slow and retractile, often be be caused by of damage of oil seal of oil cylinder piston. Overload protects overload protection to divide kind of case, it is oil pump in locomotive condition, when overload or terminal of journey of some of place of oil cylinder piston, relief valve overflow of 3 can automatic open, realize the overload protection below device movement operating mode thereby. 2 be do not work in oil pump, namely device is in bear to protect position, when oil cylinder is crossed big outside force effect, overflow of automatic open of " of overload a powerful person, realize device to stop thereby turn the overload protection below operating mode. The hand moves the utility of shut-off valve to be in locomotive operating mode when device, when meeting the special condition such as occurrence breakdown of power cut or circuit, can open a hand to move shut-off valve 6, oil of oil cylinder A, B the mouth is interlinked with gasoline tank at the same time, make lever of oil cylinder piston is extended or retractile to journey terminal, this valve is closed again after waiting for trouble removal, make unit operates afresh. Unit of power of this kind of small-sized hydraulic pressure and traditional drive system photograph compare 3 characteristics have the following characteristic: Form a complete set is simple this product is produced by professional production manufacturer, and manufacturer of production of fluid drive equipment or the company that have technical reformation but according to relevant technology parameter, choose this product directly to it form a complete set, avoided vintage facility construction especially complex and cost is advanced element, do not need to configure vitta, mount oil cylinder, should put through only each process that relevant circuit can complete hydraulic pressure system to install: Again criterion, all sorts of pressure in this device dominate a powerful person or family all by manufacturer home setting, the user need not be moved again, accordingly, saved those who make stage equipment to assemble greatly reach debug workload. Compact electromotor, oil pump, a powerful person reachs the structure gasoline tank closes an organic whole, join with the oil path of oil cylinder need not vitta, composition of equipment whole structure is quite reasonable and handy. When economic energy resources should need hydraulic pressure system to work only, just start motor, this hydraulic pressure system to discontinuous job and for the detached without motivation, facility that joins unit, the power that the airborne travel that executive component of nonexistent hydraulic pressure is issueing without bear brings is used up with mechanical wear. As a result of airtight installation, the state of affairs of the discharge outside oily fluid and pollution is quite little, improved the service life of device greatly, reduced use with maintenance cost, also improved environmental protection quality at the same time. On the safe side is divided because of this device outside installing relief valve, still installed fluid to accuse one-way a powerful person, overload a powerful person and electromotor to cross bear circuit the protective element such as automatic breaker, the negative charge that suspends movement to fall to the system maintains when reaching normal movement crossed bear protection to all offer reliable assurance. This plants 4 application circumstance gearing of motivation of new-style hydraulic pressure, apply to oil cylinder not much, the fluid drive equipment with lesser power. If Japan already had product of two kinds of series to come out at present, a kind of pressure is 3.

4MPa, discharge is 1.

1L/min, another kind of pressure is 6.

4MPa, discharge is 0.

9L/min, dimension of its oil cylinder all has Ø20 ~ Ø30 and Ø20 ~ Ø40 two kinds of norms, piston lever journey has 150, 200, 250, 300 with 5 kinds of 350 norms. Already was applied at door of van side side shut, of combine harvester knife coming back litre fall those who reach its case shut, on the machine that sweep snow sweep Xue Qisheng to fall and vertical garage jockeys mediumly among the mechanical equipment such as spacing and overload protector. Because transform device of this kind of new-style hydraulic pressure has outstanding advantage, having extensive development and applied perspective. CNC Milling CNC Machining
