Embodiment Construction

[0023] Combine Figure 1 ~ Figure 7 For manual plunger precision pressurizing pumps, the design basis is based on the theory of the effective volume modulus of oil. To explain the theory of the effective volume modulus of oil, the effective volume modulus of oil must be defined first. e as follows:

[0024] K e = ΔP × V - ΔV

[0025] Effective bulk modulus of elasticity for oil K e The explanation of is helpful to the understanding of the theory of the effective bulk elastic modulus of oil. Any elastic modulus can be explained by stress and strain. For the bulk elastic modulus of oil, the stress refers to the pressure of the oil, and the strain refers to the oil. The rate of change of liquid volume. The compressibility of liquid refers to the nature of the volume reduction of oil under pressure. When the pressure is P, the corresponding volume of the pressure oil is V. When the pressure increases by ΔP, the volume decreases by ΔV. The manual plunger prec...

Abstract

A manual and precision plunger pressurizing pump comprises a plunger pressurizing structure, a mechanical drive structure and a frame, wherein the frame comprises a baseplate, a front support upright plate and a rear support upright plate; the plunger pressurizing structure comprises an outer cylinder body, a plunger guide sleeve, a plunger and a cylinder body end cover; the plunger guide sleeve is mounted inside the outer cylinder body; the plunger is mounted in the plunger guide sleeve in a sleeving manner, and moves frontward and backward along an inner hole of the plunger guide sleeve; the mechanical drive structure comprises a trapezoid screw rod mechanism, a planetary gear retarding mechanism and a guide rail structure; the guide rail structure comprises a guide rail pull rod, a guide sleeve, screw rod nut fixing plates and a plunger driving sleeve; the trapezoid screw rod mechanism comprises a trapezoid screw rod shaft and a screw rod nut; the screw rod nut is in meshed transmission with the trapezoid screw rod; the planetary gear retarding mechanism comprises a sun gear, a planet gear, an outer gear ring and a planet wheel carrier. The manual and precision plunger pressurizing pump provided by the invention can realize precision pressure regulation under middle / low pressure especially high pressure, and the pressure regulation process is stable without fluctuation.

Description

Technical field [0001] The invention relates to the field of manual hydraulic pumps, in particular to a manual plunger precision pressurizing pump with high precision and high pressure resistance. Background technique [0002] The pressurization of systems, drives, and actuators is usually achieved by pressurizing devices. Common pressurizing devices and equipment at the current stage include hydraulic systems (with hydraulic control valves), electric pressure test pumps, manual hydraulic pumps, and manual pressure test pumps. . In common application areas such as pressure detection and experimental pressurization, such as specific occasions such as safety equipment, instrument leak detectors, and experimental pressurization devices, manual pressurization devices are widely used due to their simple structure, low cost, and convenient installation, debugging and maintenance. . However, for the existing manual pressurizing device, its application range is also greatly limited due...
