Problems solved by technology

[0002] During the operation of the traditional single-piston metering pump, the liquid inlet and outlet in the pump body are carried out separately, which makes the two oil ports of the single-piston metering pump not directly connected to the two ends of the same driven element, but needs to be fuel tank to work
The fuel tank will increase the size and weight of the equipment
In addition, the hydraulic medium will accelerate aging in contact with air in the oil tank, resulting in shortened hydraulic system maintenance cycle and increased maintenance costs

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] Such as figure 1 As shown, an electromagnetic two-way metering pump includes a pump casing 1, a pump liquid piston 2, a first variable check valve 3, a second variable check valve 4, a third variable check valve 5, and a piston drive components and control circuits. The pump casing 1 is provided with a piston sliding chamber 1-1, a pump liquid flow channel 1-2, a first interface chamber 1-3 and a second interface chamber 1-4. Both ends of the piston sliding chamber 1-1 communicate with the first interface chamber 1-3 and the second interface chamber 1-4 respectively. The two ends of the pump liquid channel 1-2 communicate with the first interface cavity 1-3 and the second interface cavity 1-4 respectively.

[0035]The piston sliding cavity 1-1 is in the shape of a symmetrical stepped hole. The pump liquid piston 2 is arranged in the middle part of the piston slid...

Abstract

The invention discloses an electromagnetic bidirectional metering pump, a hydraulic slide table and a driving method thereof. During the operation of the traditional single plunger metering pump, the liquid in and out of the pump body are separated. The invention relates to an electromagnetic bidirectional metering pump, which comprises a pump housing, a pump liquid piston, a first variable one-way valve, a second variable one-way valve, a third variable one-way valve and a piston driving assembly. The pump casing is provided with a piston sliding cavity, a pump liquid flow channel, a first interface cavity and a second interface cavity. The first variable one-way valve, the second variable one-way valve and the third variable one-way valve are respectively installed in the first interface cavity, the second interface cavity and the pump liquid flow channel. In the present invention, the two-way metering pump can realize two-way pumping through the cooperation of three variable one-way valves and pumping pistons. Since the volume of the hydraulic medium pumped out in a bidirectional stroke of the pumping piston is determined, the present invention can accurately realize bidirectional quantitative pumping.

Description

technical field [0001] The invention belongs to the technical field of metering pumps, and in particular relates to an electromagnetic bidirectional metering pump, a hydraulic slide table and a driving method thereof. Background technique [0002] During the operation of the traditional single-piston metering pump, the liquid inlet and outlet in the pump body are carried out separately, which makes the two oil ports of the single-piston metering pump not directly connected to the two ends of the same driven element, but needs to be fuel tank to work. The fuel tank will increase the size and weight of the equipment. In addition, the contact of hydraulic medium with air in the oil tank will accelerate the aging, which will shorten the maintenance period of the hydraulic system and increase the maintenance cost. Contents of the invention [0003] The object of the present invention is to provide an electromagnetic bidirectional metering pump, a hydraulic slide table and a d...
