Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model (Fig. 1: solid line partly is gas circuit and liquid road, and dotted portion is a control wiring) piston 9 is installed the back with cylinder 8 and is formed A, B, four chambeies of C, D, and wherein, A, D are air cavity, and B, C are oil pocket.Hydraulic oil is through oil pump 13, and straight-through (state among the figure) that entered filter 11, selector valve 15 by oil sump 14 enters the B chamber, promotes piston 9 and moves upward, and simultaneously, the oil in C chamber then through straight-through (state among the figure), the oil cooler 12 of selector valve 15, is got back to oil sump 14.In the process that piston 9 moves upward, A chamber volume dwindles, and gas pressure increases, and suction valve 6 cuts out, and outlet valve 7 is opened, and gas is discharged in the gas holder through supercooler 2, second ball valve 4 and one-way valve 5, forms the exhaust process in A chamber.In this process, when the A cavity pressure surpasses exhaust pressure, this moment A cavity pressure=B cavity pressure-C cavity pressure+D cavity pressure.Because the C chamber communicates with oil sump, promptly communicates with atmosphere, can disregard, and the D chamber is the gas suction pressure.Therefore, Ci Shi A cavity pressure (being exhaust pressure)=oil pressure+suction pressure.Hence one can see that, and the suction pressure of gas is big more, and required oil pressure is just more little, and power demand is just more little.In the process that piston 9 moves upward, D chamber volume can increase, and cavity pressure reduces, and suction valve 6 is opened, and gas enters the D chamber through first ball valve 1 from suction valve 6, produces the intake process in D chamber.When piston 9 moved to top dead center, piston 9 can contact limit sensors 16, and 15 commutations of control selector valve make selector valve 15 be in the state that intersection communicates.At this moment, pressure oil will flow to the C chamber, and the oil in the B chamber is just got back to oil sump 14, and simultaneously, D finishes compression process in the chamber, and intake process is then finished in the A chamber.So repeatedly.In compression process, if the gas circuit overpressure, gas then enters in the atmosphere by safety valve 3; If the oil circuit pressure transient, 10 effect of playing voltage stabilizing of accumulator; If oil circuit overpressure, pressure oil then can directly be got back to oil sump 14 by relief valve 17.At this moment, by A cavity pressure (being exhaust pressure)=oil pressure+suction pressure as can be known, the required working pressure of oil pump is: row pressure-entrance pressure.Under the certain situation of row pressure, entrance pressure is high more, and required pressure fuel pump is more little, when entrance pressure for hour, the required pressure maximum of oil pump, this moment, power demand also was maximum (establishing power is W1).And traditional crank-connecting rod compressor, when operating mode was identical, entrance pressure was high more, power demand is big more, to join the power of driving machine also big more.When entrance pressure for hour, power demand minimum (establishing power is W2), but the power of driving machine can not hour join by entrance pressure, the power (establishing power is W3) of required driving machine is joined when can only be by entrance pressure maximum.From theory, W1=W2, W3＞W2.In view of this, it is little that this model utility is joined driving machine power, thereby reach energy-conservation and save the purpose of operating cost.
The utility model can change the oil circuit unit into hydraulic workstation (with being installed together in all hydraulic sets of elements); For using two stage compression, increased a cylinder 8, the one-level compression is become two stage compression, can reduce the pressure ratio of gas like this, comparatively favourable to compression process.Certainly can also be increased to three grades or more, the pressure of required like this oil pump just reduces relatively, and it is more favourable to work, but product cost can increase; Simultaneously, if increase discharge capacity, the number of cylinders that only needs to increase each grade gets final product.
The double-action hydraulic cylinder of the utility model model utility compressor is that oil hydraulic cylinder and compression cylinder are united two into one, one end of cylinder is a hydraulic oil, the other end is a compressed media, the centre separates with piston 9, piston 9 is in the process that moves up and down, and in the time of near sensing body 29 moves to sensing joint 27, limit sensors 16 will produce electrical signal, the commutation of pilot pressure oil reaches the purpose that piston 9 commutates.This control has overcome the difficult problem of prior art in piston 9 commutations.On structure, the operation part is than the confidential much less of conventional compression, and easily damaged parts is a standard piece, and it is convenient to change.Adopt distance control, overcome the air valve of traditional compressor and the Strike note of movement parts, reduced noise.
The content that is not described in detail in this specification belongs to related domain professional and technical personnel's known prior art.
