Description

一种手动泵 a hand pump

技术领域:Technical field:

本实用新型涉及一种手动泵,尤其涉及一种用于抽取液体,并可供学校作为教学产品生产的手动泵。The utility model relates to a hand pump, in particular to a hand pump used for pumping liquid, which can be produced by schools as a teaching product.

背景技术:Background technique:

在电力、建筑等行业在野外工地操作中,有时需将液体(如润滑油)从储存器中抽往需用之处,如果用液压泵,在低速运转时泵内泄漏严重;高速运转时,泵压力稍有提高,但由于泵的磨损及内泄,容积效率显著下降,很难达到额定压力,液压泵长时间工作又加剧了磨损,油温升高,由此造成液压元件磨损及密封件的老化、损坏,丧失密封能力,液压油变质,最后导致故障发生,目前,市场上还没有手动的直接抽取液体的装置。In electric power, construction and other industries in field operations, sometimes it is necessary to pump liquid (such as lubricating oil) from the storage to the place where it is needed. If a hydraulic pump is used, the leakage in the pump is serious when it is running at low speed; when it is running at high speed, The pressure of the pump is slightly increased, but due to the wear and internal leakage of the pump, the volumetric efficiency is significantly reduced, and it is difficult to reach the rated pressure. The long-term work of the hydraulic pump increases the wear and the oil temperature rises, which causes the hydraulic components to wear and the seals The aging, damage, loss of sealing ability, deterioration of hydraulic oil, and finally lead to failure. At present, there is no manual device for directly extracting liquid on the market.

实用新型内容:Utility model content:

本实用新型针对现有技术的不足,提供了一种用于抽取液体,并可供学校作为教学产品生产的手动泵。The utility model aims at the deficiencies of the prior art, and provides a manual pump for pumping liquid, which can be produced by schools as a teaching product.

为实现以上目的,本实用新型采用的技术方案如下:For realizing above object, the technical scheme that the utility model adopts is as follows:

一种手动泵,由阀座、出油控制单向阀、进油控制单向阀、曲柄活塞机构、手柄组成;出油控制单向阀和进油控制单向阀设置于阀座内,通过两个单向阀控制流体的流动方向,曲柄活塞机构设置在活塞腔内,曲柄活塞机构与手柄连接在一起。A manual pump is composed of a valve seat, an oil outlet control check valve, an oil inlet control check valve, a crank-piston mechanism, and a handle; the oil outlet control check valve and the oil inlet control check valve are arranged in the valve seat, through Two one-way valves control the flow direction of the fluid, the crank-piston mechanism is arranged in the piston cavity, and the crank-piston mechanism is connected with the handle.

本实用新型采用手柄的回转运动转化为活塞的复运动来实现活塞腔内容积的改变,通过在泵底阀座内的出油控制单向阀、进油控制单向阀来控制流体的流动方向;采用此结构的手动泵具有一定的市场需求,加之设计制作时需一定的机械、液压常识,其制作也可作为一个学生机械、液压的综合实训项目。The utility model converts the rotary motion of the handle into the compound motion of the piston to realize the change of the volume in the piston cavity, and controls the flow direction of the fluid through the oil outlet control check valve and the oil inlet control check valve in the valve seat at the bottom of the pump. The manual pump with this structure has a certain market demand, and certain mechanical and hydraulic common sense is required when designing and manufacturing. Its production can also be used as a comprehensive training project for students' mechanical and hydraulic pressure.

附图说明:Description of drawings:

图1为本实用新型结构示意图;Fig. 1 is the structural representation of the utility model;

具体实施方式:Detailed ways:

如图1所示,一种手动泵由阀座1、出油控制单向阀2、进油控制单向阀3、曲柄活塞机构4、手柄5组成;实施时,摇动手柄5,曲柄活塞机构4向左运动,活塞腔容积变大,形成负压,出油控制单向阀2关闭,进油控制单向阀3打开,此时流体由储存器被吸入活塞腔,当活塞支运动到最大行程后,曲柄活塞机构4由右向左运动,活塞腔容积变小,进油控制单向阀3关闭,出油控制单向阀2打开,液体由一处被输送到另一处。As shown in Figure 1, a manual pump consists of a valve seat 1, an oil outlet control check valve 2, an oil inlet control check valve 3, a crank piston mechanism 4, and a handle 5; during implementation, shake the handle 5, and the crank piston mechanism 4 Move to the left, the volume of the piston chamber becomes larger, forming a negative pressure, the oil outlet control check valve 2 is closed, and the oil inlet control check valve 3 is opened, at this time the fluid is sucked into the piston chamber from the reservoir, when the piston branch moves to the maximum After the stroke, the crank-piston mechanism 4 moves from right to left, the volume of the piston cavity becomes smaller, the oil inlet control check valve 3 is closed, the oil outlet control check valve 2 is opened, and the liquid is transported from one place to another.

本实用新型具有结构简单、运行可靠、方便实用、不易泄漏等优点,具有极大的推广价值。The utility model has the advantages of simple structure, reliable operation, convenience and practicality, not easy to leak, etc., and has great popularization value.
