Energy-saving type reciprocating high-pressure plunger pump

Abstract

An energy-saving type reciprocating high-pressure plunger pump is a novel reciprocating high-pressure plunger pump composed of a planetary gear reduction variable-frequency motor, a pressure adjusting valve, a water outlet channel assembly, a water inlet channel assembly, forcing valves, a piston rod, intake valves, cylinder blocks, a piston, cylinder block glands, a piston rod clamp, a guide rail, a sector gear and racks. Compared with the prior art, the energy-saving type reciprocating high-pressure plunger pump has the advantages of saving energy, being environmentally friendly, advanced in technology, novel in structure, convenient to install and low in manufacturing cost and use cost. The energy-saving type reciprocating high-pressure plunger pump is a upgraded and updated novel product and can be widely applied to conveyance of high-pressure liquid, high-pressure scale removal of metallurgy and rolling mills and scale removal of the building industry, the chemical engineering industry, the shipbuilding industry, the papermaking industry and the like, high-pressure long-distance fire extinguishment of fire fighting trucks and high-pressure pumps of wet sand blasting machines.

Description

technical field [0001] The invention relates to a high-pressure plunger pump, in particular to an energy-saving reciprocating high-pressure plunger pump. Background technique [0002] The high-pressure plunger pump is an important device of the hydraulic system.

[0002] The high-pressure plunger pump is an important device of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize liquid suction and pressure. It has high rated pressure, compact structure and high efficiency. It is widely used in the occasions where high pressure, large flow and flow need to be adjusted, such as process pumps in petroleum, chemical and fertilizer industries, high-pressure descaling in metallurgy and rolling mills, construction, chemical industry, shipbuilding, For descaling in papermaking and other industries, and high-pressure long-distance fire fighting for fire trucks, most of the liquid sandblasting machines used in China in recent years also use high-pressure plunger pumps; This structure has defects such as high energy consumption, complex structure, high cost, unstable operation, and loud noise

Especially with the development of science and technology, higher and newer requirements are put forward for high-pressure plunger pumps. For example, the demand for oil in various countries in the world continues to increase, which makes the depth of oil wells in oil fields continue to deepen and increase production. In order to maintain formation energy, major oil fields generally use The three-plunger high-pressure water injection pump has become more and more prominent in the problem of under-injection under high pressure. It has become increasingly difficult to meet the actual needs in terms of process structure and adaptability to complex working conditions; in addition to deep wells in oil fields, metal surface treatment Technology, high-rise building fire-fighting and other industries have put forward new requirements for high-pressure, high-efficiency, energy-saving and environmental protection for existing high-pressure plunger pumps; for this reason, I have designed and developed an energy-saving reciprocating high-pressure plunger pump, from the plunger pump operating mechanism Starting from the reciprocating working mode of the plunger, the crank crankshaft connecting rod mechanism is changed to a sector gear driven rack running mechanism. Under the same speed and pressure conditions, the motor power is reduced from 90KW to 22-27KW frequency conversion speed regulation, which saves a lot energy, reduce operating costs, adopt the working mode of four cylinders and eight connections, improve the uniformity and high flow rate of the pump liquid, adjust the flow rate and pressure of the output liquid, and solve many defects of the existing high-pressure plunger pumps in one fell swoop, and meet various requirements. The industry's new demand for high-pressure plunger pumps has broad application prospects and is a new choice for the development direction of high-pressure plunger pumps.
