High-pressure water pump with compact volume

Abstract

The invention discloses a high-pressure water pump with a compact volume. The high-pressure water pump with the compact volume is characterized by comprising a pump body, a mounting hole penetrating left and right is formed in the pump body, a left end cover is fixedly mounted at the left end of the pump body, and a right end cover is fixedly mounted at the right end of the pump body; a piston body moving left is arranged in the mounting hole; a left column plug hole with the open right end is formed in the left end cover, a right column plug hole with the open left end is formed in the rightend cover, a left column plug slidably connected into a left column plug cavity is arranged on the left side of the piston body, and a right column plug slidably connected into a right column plug hole is arranged on the right side of the piston body; a left-in one-way valve and a left-out one-way valve are arranged in the left end cover, and a right-in one-way valve and a right-out one-way valveare arranged in the right end cover; an opening P, an opening T1 and an opening T2 are formed in the outer circumferential side surface of the pump body; and a pump control assembly used for controlling the piston body to move left and right in the mounting hole is arranged in the mounting hole. The high-pressure water pump with the compact volume is highly integrated in integral design, and savesspace and parts; and hydraulic automatic control reversing is achieved, and electronic control is not needed.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to a compact high-pressure water pump. Background technique [0002] At present, in the fire rescue of high-rise buildings, the water supply height requires that the water pump can generate relatively high pressure. In the invention patent, the high-pressure water pump used is a plunger high-pressure water pump system driven by a double-piston cylinder. The pressure generated by it can be greater than 10MPa, and the theoretical water supply height can reach more than 900 meters, so as to meet the supply of fire water for super high-rise buildings. However, the water pumps in the prior art are mainly composed of oil cylinders and water cylinders. By using electromagnetic reversing valves and displacement sensors to control the direction of the oil cylinders, and then drive the water cylinders to absorb and drain water, not only the volume is large, but the pipeline is...

Problems solved by technology

However, the water pumps in the prior art are mainly composed of oil cylinders and water cylinders. By using electromagnetic reversing valves and displacement sensors to control the direction of the oil cylinders, and then drive the water cylinders to absorb and drain water, not only the volume is large, but the pipeline is connected It is complicated, and the reversing of the oil cylinder is controlled by a proximity switch sensor, which is unstable and unreliable; the control circuit part of the reversing device is controlled by a circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process. Maintenance is very difficult; if the existing reversing device is continuously energized for a long time, it is easy to damage small devices, which cannot meet the requirements of long-term energization, and also affects production efficiency to a certain extent
