Described plunger displacement pump is radial axle flow, is capable of achieving pressure limiting, invariable power, the regulation of constant flow；The type of hydraulic cylinder
It is double acting single-piston rod, mounting means is that axial foot stool external form is installed；The rated pressure of described hydraulic cylinder is 16MPa.
It is always in discontinuous operation due to pushing away bender, it is desirable to which moment supplements a large amount of hydraulic oil, therefore is hung up after preliminary filter
One accumulator；After hydraulic system installing accumulator, can auxiliary feed-oil, reduction plunger pump capacity, reduction electricity when system works
Motivation power, makes whole system size small, and lightweight, price is low；
In bender hydraulic system is pushed away, when pressurize is carried out in motion process with slow-motion, hydraulic oil enters accumulator, hydraulic pressure
Oil is stored into, and in backhaul, accumulator is with plunger displacement pump while fuel feeding, makes hydraulic cylinder obtain more than plunger displacement pump fuel delivery
Quick motion.
The utility model patent by setting accumulator, when pushing away bender moment and requiring supplementation with a large amount of hydraulic oil, accumulator
Can be simultaneously hydraulic system fuel feeding with plunger displacement pump, improve the charge oil pressure of hydraulic system, increased moment repairing amount；By setting
Put the location of three-position four-way valve so that hydraulic system preferably to push away bender work can improve the safety system of machine
Number.
