Abstract
The invention discloses a CC serial single-cylinder hydraulic system of a single-cylinder conical crusher. The CC serial single-cylinder hydraulic system comprises a two-way hydraulic pump, a cartridge valve and a hydraulic cylinder. The CC serial single-cylinder hydraulic system is characterized in that the two-way hydraulic pump, the cartridge valve and the hydraulic cylinder are connected by oil pipes; an oil sucking filter is connected between the two-way hydraulic pump and an oil tank; a pressure pipe filter is connected between the cartridge valve and the hydraulic cylinder; the two-way hydraulic pump is driven by a motor; and the cartridge valve is connected with a pressure transmitter, a pressure gauge for measuring the pressure and a switch. The CC serial single-cylinder hydraulic system can vertically act the hydraulic cylinder, is high in speed adjusting stability, is simple in structure, and can be stably stopped in a needed position.
Description
Technical field
The hydraulic system of the present invention relates to a kind of hydraulic pressure installation, particularly single cylinder, can single channel carrying out work.
Background technique
At present, the oil suction of known hydraulic system, oil return are two paths, during oil suction, by oil hydraulic pump, fluid is sucked to oil pump from fuel tank and reinject oil hydraulic cylinder, during oil return, the fluid of oil hydraulic cylinder is subject to the compressing of piston deadweight in oil hydraulic cylinder to make fluid get back to fuel tank by selector valve.When oil return, if load is larger, in oil hydraulic cylinder, the pressure of fluid can be very large, and when oil return control valve is opened, when the oil in oil hydraulic cylinder flow back into fuel tank from oil circuit, piston rotation perdurability is too fast, uncontrollable.
Summary of the invention
For overcoming the uncontrollable deficiency of hydraulic system more complicated and speed.The invention provides a kind of single-cylinder hydraulic system, this hydraulic system is system simple in structure but also can effectively control rate of descent not only.
The present invention is achieved like this.A kind of single-cylinder hydraulic system, comprise bidirectional hydraulic pump, cartridge valve, oil hydraulic cylinder, it is characterized in that bidirectional hydraulic pump, cartridge valve and oil hydraulic cylinder link together with oil pipe, between bidirectional hydraulic pump and fuel tank, connect an oil absorption filter, between cartridge valve and oil cylinder, connect a pressure piping filter, bidirectional hydraulic pump is driven by motor, described cartridge valve Bonding pressure transmitter and for pressure gauge and the switch of pressure measurement; One-way valve, Differential Relief Valve, the throttle valve for release for the protection of oil cylinder overload of the built-in solenoid valve of described cartridge valve, direct-acting overflow valve for the protection of system pressure, one bidirectional hydraulic pump idle running when preventing oil return, described throttle valve is closable.
When bidirectional hydraulic pump forward, bidirectional hydraulic pump is from fuel tank oil suction, and fluid enters into oil hydraulic cylinder by solenoid valve.If hydraulic cylinder piston will be parked in to the position needing only need stop bidirectional hydraulic pump.Bidirectional hydraulic pump oil suction oil sump tank from pipeline when bidirectional hydraulic pump reverses, if open solenoid valve, bidirectional hydraulic pump is oil suction oil sump tank from oil hydraulic cylinder, now the speed of fluid is controlled by bidirectional hydraulic pump, not affected by the load force on oil hydraulic cylinder, is only subject to the impact of bidirectional hydraulic pump, thereby reach the object of controlling rate of descent, simultaneously when the load force of oil hydraulic cylinder too hour, if the fluid of oil hydraulic cylinder only cannot drain by load force effect, reversion that so can be by bidirectional hydraulic pump is by fluid sucking-off.If closed electromagnetic valve, oil hydraulic pump cannot suck back fuel tank oil from oil hydraulic cylinder, and now bidirectional hydraulic pump is by one-way valve oil suction oil sump tank from fuel tank on side, prevents that the idle running of bidirectional hydraulic pump from burning.
The invention has the beneficial effects as follows: the hydraulic system that it is a kind of single cylinder, can single channel carry out work, oil hydraulic cylinder rate of descent is controlled, and the reversion that the fluid in oil hydraulic cylinder can be by bidirectional hydraulic pump is fluid sucking-off, can prevent that the idle running of bidirectional hydraulic pump from burning.Oil return must be passed through bidirectional hydraulic pump, and described solenoid valve and relief valve leak and be and small when closing; This hydraulic system good stability, simple in structure and can rest on a position needing.
