Wherein, 1, cylinder bottom, 2, outer cylinder body, 3, piston rod, 4, inner cylinder body, 5, mounting flange, 6, guide sleeve, the 7, first oil inlet
Mouthful, the 8, second oil inlet, 9, oil outlet.
Specific embodiment
As shown in Figure 1, a kind of blow molding machine energy-saving hydraulic system oil cylinder, including piston rod 3, cylinder bottom 1, inner casing
Body 4 and outer cylinder body 2, the inner cylinder body 4 are located in outer cylinder body 2, and inner cylinder body 4 is connect with cylinder bottom 1, and piston rod 3 is socketed in outer cylinder body 2
Between inner cylinder body 4, inner cylinder body 4 and piston rod 3 are hollow structure, and inner cylinder body 4 is connected to piston rod 3, and cylinder bottom 1 is equipped in connection
First oil inlet 7 of cylinder body 4, cylinder bottom 1 are additionally provided with the second oil inlet 8 and are communicated between inner cylinder body 4 and outer cylinder body 2, and outer cylinder body 2 is set
There is oil outlet 9, the inner cylinder body 4 is bolted with cylinder bottom 1, and the outer cylinder body 2 is externally connected with mounting flange 5.
It is equipped with first sealing device between the inner cylinder body 4 and piston rod 3, second is equipped between piston rod 3 and outer cylinder body 2
Sealing device.It is socketed with guide sleeve 6 outside the piston rod 3, third sealing device, guiding are equipped between guide sleeve 6 and piston rod 3
Set 6 is bolted with outer cylinder body 2.The first sealing device, the second sealing device, third sealing device and guide sleeve
Sealing between 6 and outer cylinder body 2 is using rubber ring, rubber pad or packing, the sealing between inner cylinder body 4 and piston rod 3,
Sealing between piston rod 3 and outer cylinder body 2, between the sealing and guide sleeve 6 and piston rod 3 between guide sleeve 6 and outer cylinder body 2
Sealing be technology contents that those skilled in the art can be realized.
Working principle: when cylinder diameter is larger, and piston rod 3 stretches out same distance, the liquid that ordinary construction type oil cylinder needs holds
Amount is big, and in one timing of pumping plant output flow, the time required for piston rod 3 stretches out in the process is long, therefore it is slow to stretch out speed.This is practical new
When this energy-saving oil cylinder of type, increase inner cylinder body 4, inner cylinder body 4 is bolted with cylinder bottom 1, relatively fixed.Piston rod 3 exists
When stretching, from 7 oil inlet of the first oil inlet, piston rod 3 is pushed to stretch out.The second oil inlet 8 passes through prefill valve and pumping plant fuel tank at this time
It is connected, directly pumps from fuel tank.When the length required for reach, by solenoid valve control, the first oil inlet 7 and second into
The oil inlet simultaneously of hydraulic fluid port 8, it is ensured that oil cylinder is not reduced using power.During this when piston rod 3 stretches out same distance, due to inner casing
4 cylinder diameter of body is smaller, and the liquid capacity that oil cylinder needs is with regard to small, and in one timing of pumping plant output flow, piston rod 3 is required during stretching out
Want the time just few, therefore it is fast to stretch out speed.Practice operation in, in the case where meeting requirement, can with low-power machine,
Low-capacity pump station replaces heavy-duty motor, big flow pumping plant, reduces production cost, while the institute using equipment is greatly saved
The cost needed.
