1. How to adjust the stroke of the metering pump from 0 to 100
Adjusting the stroke of the metering pump requires following the steps to ensure safety and accurate matching of flow rate. Before starting the preparation work, the power must be cut off and the pump body must be kept in a stopped state. Prepare a wrench or adjustment tool, confirm that there are no obstacles in the surrounding environment, and avoid accidental collisions during operation. two The positioning stroke adjustment mechanism may be located on the side, top, or adjustment disc area of the pump head depending on the pump model. Common structures can be divided into three categories: knob type: with a 0-100% scale on the surface, usually changing the stroke by rotation. Handle type: By pushing and pulling the handle, the position of the mechanical linkage can be changed, and the scale indication needs to be observed during adjustment. Adjust the dial: Mark the percentage on the dial and rotate the chain sock to align the pointer with the target value. three Manual adjustment method • Knob operation: Rotate clockwise to increase the stroke (such as from 30% to 80%), and counterclockwise to decrease. Slow rotation is required to avoid skipping the target value. Handle operation: Push to the bottom corresponds to 100% stroke, pull back to the bottom corresponds to 0%. Some models require the use of limit screws to fix the handle position. Adjustment disk operation: Loosen the fixing bolts, rotate the adjustable reed disk to the desired percentage, and then re lock it to ensure that the scale is aligned with the shed. four If the pump body is equipped with an electric actuator for electric adjustment, the numerical value needs to be input thr
2. How much does the central oxygen supply system cost?
The price of the central oxygen supply system varies greatly depending on the brand, specifications, specific usage scenarios, and configuration, ranging from large-scale hospital projects costing tens of thousands of yuan to simple configurations costing thousands of yuan. It needs to be determined according to specific needs.
. 1. Price reference for projects of different scales. According to publicly available procurement information, the price range for hospital level central oxygen supply systems is usually between 200000 yuan and 500000 yuan. - Maigaiti County Peoples Hospital project: 434800 yuan. - Xiyuyu Lake Management District Peoples Hospital project: 202500 yuan. This type of price includes complete solutions such as terminal equipment, pipeline systems, and intelligent control systems.2. Price range for component level products. For small clinics or household users, modular proc
