As shown in fig. 1 and 5, which are schematic views illustrating the assembly of the oil pump, the oil pump of the present embodiment operates as follows:
the oil inlet passage 18 is connected with an oil inlet joint, oil flows in from the oil inlet joint and flows to the oil inlet one-way valve inlet 34 along the oil inlet passage 18 and the communication passage I11, the two-way electromagnetic valve 2 is electrified, the coil assembly enables the static iron core 22 to generate magnetism, the static iron core 22 attracts the upper moving iron 21 and the lower moving iron 23, the lower moving iron core 23 moves upwards to drive the plunger 9 to move upwards in the plunger sleeve 91, the space of the variable cavity 116 is enlarged, the oil pressure at the oil inlet one-way valve outlet 35 is reduced, the oil at the oil inlet one-way valve inlet 34 overcomes the jacking force of the oil inlet one-way valve spring 33 and jacks the oil inlet one-way valve plug 32 under the action of the atmospheric pressure, the oil can pass through the oil inlet one-way valve outlet 35 (as can be seen from the figure, the oil inlet one-way valve 3 and the oil outlet one-way valve 4 are arranged in the one-way valve installation cavity 19, the two parts are separated by adopting a sealing ring between the two parts, so that the oil at the oil inlet can not seep to the oil outlet part), The second connecting channel 12 enters the variable cavity 116, and at the moment, because the variable cavity 116 is expanded, the oil pressure at the inlet 44 of the oil outlet one-way valve cannot push the oil outlet one-way valve plug 41;
when the two-way electromagnetic valve 2 is powered off, the static iron core 22 loses magnetic force, the plunger 9 and the lower movable iron core 23 reset under the action of the movable iron core return spring 24, the variable cavity 116 becomes small, oil in the variable cavity 116 is pressed back by an original circuit, and at the moment, under the action of oil pressure and the return spring, the oil inlet one-way valve plug 32 resets to plug the oil inlet one-way valve inlet 34; at the moment, as the oil pressure at the inlet 44 of the oil outlet one-way valve is increased, the oil outlet one-way valve plug 42 is jacked open, so that the oil enters the circulation cavity 110 after passing through the inlet 44 of the oil outlet one-way valve, the outlet 45 of the oil outlet one-way valve and the third communication channel 13 in sequence;
the oil in the circulation chamber 110 enters the solenoid valve installation chamber 111 through the connection channel four 14 under the action of oil pressure (as can be seen from the figure, the lower part of the solenoid valve installation chamber 111 is blocked by the plunger sleeve 91, so that the oil entering the solenoid valve installation chamber 111 from the circulation chamber 110 does not flow back to the variable chamber 116), and continues to enter the oil outlet channel 25 (entering from the opening of the lower end face of the lower movable iron core 23) under the action of oil pressure until reaching the oil outlet valve plug 26 (flowing out from the opening of the upper end face of the upper movable iron core 21). When the static iron core 22 does not attract the upper movable iron core 21, the upper movable iron core 21 is jacked up under the action of the movable iron core return spring 24, at the moment, the oil outlet valve plug 26 just plugs the oil outlet 9, and oil cannot flow out; when the stationary iron core 22 attracts the upper movable iron core 21, the upper movable iron core 21 can move downwards against the acting force of the movable iron core return spring 24, so that the valve plug is far away from the oil outlet 9, and after the oil outlet 9 is opened, oil is sprayed out from the oil outlet 9 under the action of oil pressure.
Through the cooperation of the two one-way valves and the two-way electromagnetic valve 2, the oil pressure can be regularly sucked and pushed out to replace a hydraulic pump, but the suction of the two-way electromagnetic valve 2 has a pulse effect, so that the output of oil has instability, and in order to solve the defect, as shown in fig. 7, the embodiment further comprises a pressure stabilizing valve 5, wherein the pressure stabilizing valve 5 comprises a pressure stabilizing valve seat 51, an energy storage assembly 52 is arranged in the pressure stabilizing valve seat 51, and the energy storage assembly 52 is generally made of materials with elastic deformation functions, such as rubber. A pressure stabilizing valve mounting opening 114 connected with the pressure stabilizing valve seat 51 is formed in the circulation cavity 110, the energy accumulator assembly 52 is opposite to the pressure stabilizing valve mounting opening 114, when the oil pressure is too large, the pressure stabilizing valve 5 is extruded, so that the energy accumulator assembly 52 is deformed, and the space of the circulation cavity 110 is enlarged in the deformation process of the energy accumulator assembly 52, so that the effect of reducing the oil pressure is achieved; on the contrary, when the oil pressure is too small, the accumulator assembly 52 is reset to reduce the space of the circulation chamber 110, thereby achieving the effect of increasing the oil pressure.
Since the hydraulic pump has different requirements for output pressure due to different use occasions, the hydraulic pump is provided with a pressure regulating valve 6, as shown in fig. 7, in this embodiment, a pressure regulating valve mounting cavity 113 is provided on the pump body 1, a communication channel five 15 is provided between the pressure regulating valve mounting cavity 113 and the circulation cavity 110, a communication channel six 16 is provided between the pressure regulating valve mounting cavity 113 and the oil inlet channel 18, the pressure regulating valve 6 is provided in the pressure regulating valve mounting cavity 113, the pressure regulating valve 6 comprises a pressure regulating bolt 61, a pressure regulating spring 62, a pressure regulating valve seat and a pressure regulating valve port rubber 63, the pressure regulating bolt 61 is screwed in the pressure regulating valve mounting cavity 113, the screwed end of the pressure regulating bolt 61 is a hollow structure with one end open, the pressure regulating valve seat, the pressure regulating valve port rubber 63 and the pressure regulating spring 62 are located in the hollow cavity of the pressure regulating bolt 61, the pressure regulating valve port rubber 63 is blocked on the communication passage five 15 by the pressure regulating spring 62. When the oil pressure is smaller than the set range, after the oil passes through the connecting channel five 15, the hydraulic pressure acting on the pressure regulating valve port rubber 63 is smaller than the elastic force of the pressure regulating spring 62, so that the pressure regulating valve port rubber 63 is pushed to move towards the valve port, the pressure relief amount is reduced, and the outlet pressure is increased to the set range; when the oil pressure exceeds the set range, after the oil passes through the fifth communication channel 15, the pressure adjusting rubber 63 is pushed open by overcoming the spring force, the pressure relief quantity is increased, the outlet pressure is reduced to the set range, and the oil flowing into the pressure adjusting valve installation cavity 113 returns to the oil inlet channel 18 through the sixth communication channel 16.
The oil pump has the air at the time of just beginning to work, influences the pressure stability of oil pump and can not produce oil even the pump, as shown in fig. 7 and 8, this embodiment is equipped with sealing screw installation cavity 115 on the pump body 1, is equipped with contact passageway seven 17 between sealing screw installation cavity 115 and the circulation chamber 110, has seted up air bleed hole 112 on the lateral wall of sealing screw installation cavity 115, sealing screw installation cavity 115 internal thread connection has the sealing screw 7 that is used for opening and close air bleed hole 112.
