Abstract

The invention discloses a double-station hydraulic station of an internal mixer, which comprises filters (1, 5), main oil pumps (2, 6), electromagnetic reversing valves (3, 7) and one-way valves (4, 8); the filters (1, 5) are connected with oil paths of the main oil pumps (2, 6); the electromagnetic reversing valves (3, 7) are arranged on the oil paths connected with the main oil pumps (2, 6); the one-way valves (4, 8) are installed on the main oil pumps (2, 6); and the main oil pump (2) and the main oil pump (6) are shunt-wound on the oil path of the hydraulic station. In the double-station hydraulic station of internal mixer provided by the invention, two main oil pumps work alternatively. When one main oil pump works, the other one is stopped. The stopped main oil pump can be maintained and repaired, so that the working of the main oil pump cannot be influenced. Compared with the traditional structure, the double-station hydraulic station of the internal mixer has the advantages of reliable operation, convenient maintenance and long service life and the like.

Description

Duplex position banbury hydraulic station
Technical field
The present invention relates to a kind of duplex position banbury hydraulic station.
Background technique
Traditional banbury hydraulic station has only a main oil pump; As shown in Figure 1 because banbury is the machine of continuous throughout the twenty-four hour24 every days 24, main oil pump however stop energy is provided for hydraulic system; Working strength is very big; Often, influence the work of whole banbury, the serious problems that cause banbury to stop production because main oil pump breaks down.
Summary of the invention
The duplex position banbury hydraulic station that the purpose of this invention is to provide a kind of reliable, easy to maintenance, long service life.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of duplex position banbury hydraulic station; Comprise filter (1,5), main oil pump (2,6), solenoid directional control valve (3,7) and one-way valve (4,8); Said filter (1,5) is connected on the oil circuit of main oil pump (2,6); Said solenoid directional control valve (3,7) is separately positioned on the oil circuit that is connected with main oil pump (2,6); Said one-way valve (4,8) is installed in respectively on the main oil pump (2,6), and said main oil pump (2) and main oil pump (6) are connected in parallel on the hydraulic station oil circuit.
Said main oil pump (2,6) works alone respectively.
A kind of duplex position banbury of the present invention hydraulic station; Two main oil pumps carry out work by turns, and in the time of one of them main oil pump operation work, another main oil pump stops; Out-of-work this main oil pump can overhaul; The operation of main oil pump during this in not influence work is compared with traditional structure, have reliable, be convenient to advantages such as maintenance and long service life.
Description of drawings
Fig. 1 is traditional duplex position banbury hydraulic station structure schematic representation.
Fig. 2 is the structural representation of a kind of duplex position banbury of the present invention hydraulic station.
Among the figure: 1, filter; 2, main oil pump; 3, solenoid directional control valve; 4, one-way valve; 5, filter; 6, main oil pump; 7, solenoid directional control valve; 8, one-way valve.
Embodiment
As shown in Figure 2, duplex position banbury hydraulic station comprises filter 1, filter 5, main oil pump 2, main oil pump 6, solenoid directional control valve 3, solenoid directional control valve 7 and one-way valve 4, one-way valve 8; Filter 1 is connected on the oil circuit of main oil pump 2 and main oil pump 6 with filter 5, solenoid directional control valve 3 and solenoid directional control valve 7 be separately positioned on main oil pump 2 and oil circuit that main oil pump 6 is connected on, one-way valve 4 and one-way valve 8 are installed in respectively on main oil pump 2 and the main oil pump 6; Main oil pump 2 is connected in parallel on the hydraulic station oil circuit with main oil pump 6, during work, leans on the hydraulic station main oil pump that power is provided; Each parts to banbury are controlled, and filter 1 and filter 5 are as critical point, first road, and hydraulic oil at first filters through filter 1 or filter 5; Filter out the impurity in the hydraulic oil; With protection main oil pump and other hydraulic pressure original paper thereof, bring up to the needed working pressure of hydraulic system to the pressure of hydraulic oil by main oil pump 2 or main oil pump 6 then, make it can satisfy the needs that System Halt is carried out original paper; Solenoid directional control valve 3 can be controlled main oil pump with solenoid directional control valve 7 and whether carry out work; Solenoid directional control valve 3 or solenoid directional control valve 7 make main oil pump 2 or main oil pump 6 work or drain charges through switch motion, and one-way valve 4 or one-way valve 8 can be so that the pressure oil that main oil pump is got enter into the oil circuit of hydraulic system to executive component; Two main oil pumps carry out work by turns; In the time of one of them main oil pump operation work, another main oil pump stops, and out-of-work this main oil pump can overhaul; Main oil pump operation during this in not influence work, whole banbury still can normally carry out work.

Claims (2)

1. duplex position banbury hydraulic station; It is characterized in that: comprise filter (1,5), main oil pump (2,6), solenoid directional control valve (3,7) and one-way valve (4,8); Said filter (1,5) is connected on the oil circuit of main oil pump (2,6); Said solenoid directional control valve (3,7) is separately positioned on the oil circuit that is connected with main oil pump (2,6); Said one-way valve (4,8) is installed in respectively on the main oil pump (2,6), and said main oil pump (2) and main oil pump (6) are connected in parallel on the hydraulic station oil circuit.
2. a kind of duplex position banbury hydraulic station according to claim 1 is characterized in that: said main oil pump (2,6) works alone respectively.
