Description
【技术领域】[Technical field]
本发明涉及一种带开关和保护的调节结构的隔膜增压泵。The invention relates to a diaphragm booster pump with a switch and a protective regulating structure.
【背景技术】【Background technique】
隔膜泵又称控制泵，是执行器的主要类型，利用隔膜泵中隔膜的弹性，通过隔膜的往复变形造成容积的变化从而将物料吸入压出。依靠一个隔膜片的来回鼓动而改变作室容积来吸入和排出液体的。隔膜泵在过程控制中的作用是接受调节器或计算机的控制信号，改变被调介质的流量，使被调参数维持在所要求的范围内，从而达到生产过程的自动化。Diaphragm pumps, also known as control pumps, are the main type of actuators. They use the elasticity of the diaphragm in the diaphragm pump to change the volume through the reciprocating deformation of the diaphragm to suck in and expel the material. They rely on the back and forth movement of a diaphragm to change the volume of the chamber to suck in and discharge the liquid. The role of the diaphragm pump in process control is to receive the control signal of the regulator or computer, change the flow rate of the regulated medium, and maintain the regulated parameters within the required range, thereby achieving automation of the production process.
隔膜泵主要由传动部分和隔膜缸头两大部分组成。传动部分是带动隔膜片回来鼓动的驱动机构，它的传动形式有机械传动、液压传动和气压传动等。其中应用较为广泛的是液压传动。隔膜泵的优点有体积小，易于移动，占地面极小，安装简便经济；无旋转部件，通过性能好；液体无剪切流动，泵自身部件磨损小；气动泵可以浸没在介质中工作，无电源通过，安全可靠。The diaphragm pump is mainly composed of two parts: the transmission part and the diaphragm cylinder head. The transmission part is the driving mechanism that drives the diaphragm back and forth. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission. Among them, hydraulic transmission is more widely used. The advantages of diaphragm pumps are small size, easy to move, very small footprint, simple and economical installation; no rotating parts, good flow performance; liquid flow without shear, small wear of pump parts; pneumatic pumps can work immersed in the medium, no power supply, safe and reliable.
现有的隔膜增压泵的流体压力是不稳定的，当压力增大到一定量后，对隔膜增压泵影响比较大，这就需要对隔膜增压泵的流体压力进行过高保护，消掉高峰值，使进入隔膜增压泵的流体压力控制在一定的范围，对流体压力进行压力控制。The fluid pressure of the existing diaphragm booster pump is unstable. When the pressure increases to a certain amount, it has a greater impact on the diaphragm booster pump. This requires excessive fluid pressure protection for the diaphragm booster pump, eliminating the peak value, and controlling the fluid pressure entering the diaphragm booster pump within a certain range to control the fluid pressure.
【发明内容】[Summary of the invention]
本发明的目的在于克服现有技术的不足之处，提供一种达到多重控制进入隔膜增压泵的流体量和流体压力，满足各种不同流量和压力要求的工作环境的要求，适用范围广泛，调节范围可控，调节方便，结构简单，维护修理方便，结构简单，成本低，装配简便的隔膜增压泵。The purpose of the present invention is to overcome the shortcomings of the prior art and provide a diaphragm booster pump that can achieve multiple controls on the amount of fluid and the fluid pressure entering the diaphragm booster pump, meet the requirements of various working environments with different flow rates and pressure requirements, have a wide range of applications, a controllable adjustment range, convenient adjustment, a simple structure, convenient maintenance and repair, a simple structure, low cost, and easy assembly.

The water outlet pressure regulating pipe 591 passes through the water outlet control chamber 52 and the water outlet control sealing gasket 55 and communicates with the water outlet pressure chamber 58. When the water pressure in the outer ring chamber 40 is too high, water enters the water outlet pressure chamber 58 from the water outlet pressure regulating pipe 51 and pushes the water outlet control sealing gasket 55 close to the water outlet control port 54, thereby controlling the water outlet amount and water outlet pressure.
当内环腔压力太大时，水从出水补水孔56进入出水控制腔52，并从出水控制口54进入出水控制通道51，由于在出水弹性顶柱57的作用下，出水弹性顶柱57推顶出水控制密封垫55，出水量可以控制在一定范围内，When the pressure of the inner annular cavity is too high, water enters the water outlet control cavity 52 from the water outlet filling hole 56 and enters the water outlet control channel 51 from the water outlet control port 54. Because the water outlet elastic top column 57 pushes the water outlet control sealing pad 55 under the action of the water outlet elastic top column 57, the water outlet amount can be controlled within a certain range.

The water outlet pressure regulating pipe 591 passes through the water outlet control chamber 52 and the water outlet control sealing gasket 55 and communicates with the water outlet pressure chamber 58 .
如图1-图10所示本发明的进水量调节装置4和出水量调节装置5可以是横向并排设置并与进水管和出水管排成一条直线，进水控制腔盖43和出水控制腔盖53设置成一体结构，结构更简单，装配方便。如图11所示，进水量调节装置4和出水量调节装置5还可以是上、下排列设置。只是位置不一样，其它结构与图1-图6的结构相同。As shown in Fig. 1-10, the water inlet regulating device 4 and the water outlet regulating device 5 of the present invention can be arranged side by side in a horizontal direction and aligned with the water inlet pipe and the water outlet pipe, and the water inlet control chamber cover 43 and the water outlet control chamber cover 53 are arranged as an integrated structure, which is simpler in structure and convenient for assembly.
