Problems solved by technology

[0005] This structure has the following disadvantages: 1. When the cam rotates, the plunger is always affected by the lateral force, the service life is short, and it cannot adapt to the high-pressure working environment
[0006] 2. There are many power transmission parts, the structure is complex, the radial dimension is increased, and the friction loss is large
[0007] 3. The spring takes up a lot o

Embodiment Construction

[0025] The hydraulically driven pump of the present invention includes a housing 3, the main points of the structure of which are a crankshaft 5 arranged in the middle of the housing 3, and at least two plungers 4 are arranged on the circumference of the crankshaft 5 end through a crank pull ring 6; the end of each plunger 4 All parts are arranged in a plunger cylinder 2, and the end of each plunger cylinder 2 is fixed in the housing 3 through the hollow support shaft 1; the hollow support shaft 1 is provided with a through hole 7 communicating with the plunger cylinder 2.

[0026] The hollow supporting shaft 1 and the plunger cylinder 2 are evenly distributed on the circumference outside the end of the crankshaft 5 . The plunger 4 is also evenly distributed on the circumference of the end of the crankshaft 5 under the limit action of the plunger cylinder 2, so that the crankshaft 5 is evenly stressed and the service life of the crankshaft 5 is prolonged.

Abstract

The invention belongs to the field of machinery and particularly relates to a high-pressure and high-flow hydraulic drive pump and a diaphragm pump using the same. The hydraulic drive pump comprises a shell, and is mainly structurally characterized in that a crankshaft is arranged in the middle of the shell, at least two plungers are arranged on the end circumference of the crankshaft by the aid of a crankshaft pull ring, the end of each plunger is arranged in a plunger type cylinder, the end of each plunger type cylinder is fixed in the shell through a hollow supporting shaft, and a through hole communicated with each plunger type cylinder is arranged on each hollow supporting shaft. The hydraulic drive pump and the diaphragm pump using the same are small in size, simple in structure, convenient to process, long in service life and low in cost.

Description

technical field [0001] The invention belongs to the mechanical field, and in particular, the invention relates to a high-pressure, large-flow hydraulically driven pump and a diaphragm pump using the hydraulically driven pump. Background technique [0002] High-pressure and large-flow diaphragm pump is the key equipment for long-distance pipeline transportation of solid-liquid two-phase medium and pressure injection feeding transportation. It has been widely used in clean coal, coal chemical industry, coal-to-oil process in petrochemical industry, alumina production and various metal Long-distance pipeline transportation of mine concentrates and tailings. [0003] The existing high-pressure and large-flow diaphragm pumps produced at home and abroad are all arranged horizontally with three crankshaft plunger cylinders, or with double crankshaft plunger cylinders. Because the plunger cylinders are arranged horizontally, the span of the crankshaft support point is too large, an...
