Metering pump purchase all strategy: know it selected it – metering pumps, pisto
Metering pump is designed to measure liquid delivery pump. Most metering pumps and diaphragm pumps have adopted the structure? Also useful for the structure of a gear pump? Because they can maintain a constant flow independent of discharge pressure. Selection of metering pumps, there are many skills and knowledge, the current take you slowly Shopping guide editor "read" several metering pump products, hoping to help your selection.
Metering pumps with flow adjustable and non adjustable two? Broader applicability of the former. Flow mainly by changing the stroke length adjustment? Such as changing the crank radius? Plunger return trip after the stop point position and the plunger rod and the crosshead of the gap junction? Can change back and forth through the number or by a combination of two methods to adjust the flow. Although the stroke length can be adjusted from zero to the maximum? But to ensure the measurement accuracy? Generally limited to 30 ~ 100% range. Metering pump flow measurement accuracy is the accuracy of reproducibility? Usually calculated by the maximum flow rate. 10 ~ 100% adjustment range? General metering pump measurement accuracy ± 1% (special metering pump more accurate).
Metering pump according to the different flow components can be divided into piston metering pump, mechanical diaphragm metering pumps, hydraulic diaphragm metering pump, metering pump bellows. Here, we focused on different metering pumps were recommended to introduce you to several HC products, and the type of metering pump to do a review.
1, plunger-type metering pump Features: 1, lower prices. 2, flows up to 76m ³ / h, flow rate of 10% to 100% range, measurement accuracy up to ± 1%, the pressure up to 350MPa. Outlet pressure changes, the flow is almost constant.
3, able to transport high-viscosity media, not suitable for transportation of slurry and corrosive hazardous chemicals.
4, seal the packing seal, a leak, need periodic adjustment filler. Packing and plunger easy to wear, need for pressure washing of the packing ring and emissions.
5, no safety relief devices. Recommended Merchant: Pump Industry Co., Ltd. Zhejiang love ryokpo
Sale through Index: 60 Love ryokpo JX Series plunger metering pumps
Description: 1, constitute a fixed eccentric engineer
2, precision casting shell, bronze worm gear and wear-resistant ball bearings, oil lubrication of all drive components
3, pump head with separate power box completely correct, could cause the power box to prevent corrosion
4, pump head also can use electric heating type, the temperature can be arbitrarily set
5, reasonable structure, reliable performance, stable operation, convenient adjustment and simple maintenance.
Main use: JX series piston pump, a process required in accordance with a stroke can range from 0 to 100% stepless regulation of quantitative transport all kinds of liquids, and in the transport medium when the maximum stroke of measurement accuracy ± 1 % of the general machinery and equipment. Metering pump flow rate of 0.8 ~ 200L / h, for conveying temperature of -30 ~ 120 , the viscosity is 0.3 ~ 800mm2 / s of non-solid-like granular media.
