Fast circulation / low flow, 2, no cycle, 3, leakage, 4, noise, 5, parts damaged, 6, slow cycle, 7, irregular circulation, 8, other failures can be divided into a variety of possible reasons , For correct maintenance before A Air Valve: Plastic or metal valve housing bolted to pump body by four screws B Piston: Aluminum cylinder enclosed in air valve to control air flow C Cavitation: As pump inlet is supplied Reduced or absent fluid volume, pump discharge below nominal volume, in fact, the liquid chamber is not filled with fluid prior to discharge.
D Static discharge head: vertical distance from pump center line to free delivery point (in meters)
E Inlet pressure: The inlet is measured in Bar, including the specific gravity of the fluid and the flow rate F. Specific Gravity: The ratio of fluid weight to water weight at 4 ° C. The specific gravity of 4 ° water is 1.0, The vertical distance from the centerline of the pump to the pump should be above the liquid level. G Vapor pressure: All liquids generate pressure on their free surface steam. Operating pressure in any pump operating system must not be lower than the vapor pressure. Partially or completely cut off into the fluid H Viscosity: due to the presence of fluid friction, the nature of the viscosity of the fluid flow resistance of the fluid I Water hammer effect: the formation of a higher inlet static pressure on the pump to produce internal pressure Electric diaphragm pump Troubleshooting The electric diaphragm pump does not move or operates very slowly Check the air inlet filter or air filter for impurities Check if the air valve is stuck and clean the air valve with a cleaning fluid.
Check air valve for wear and tear, replace new parts if necessary.
Check the center of the seal parts condition, if severely worn, you can not achieve the sealing effect, and the air will be discharged from the air outlet. Due to its special construction, use only GLYD circles.
Check the air valve piston activity is normal.
Check the type of lubricant. If the added lubricant is above the recommended viscosity, the piston may get stuck or malfunction. Recommend the use of thin and antifreeze lubricants.
Pump moves, but with little or no liquid outflow:
Check the cavitation of the pump to reduce the speed of the pump to allow liquid to enter the chamber.
Check if the valve ball is stuck. If the operating fluid is incompatible with the pump elastomer, the elastomer will swell. Please replace the appropriate material elastomer.
Check the pump inlet connector is completely tight leak, especially near the entrance of the valve ball to be locked.
Pump air valve frozen:
Check the compressed air moisture content is too high, the installation of air drying equipment Bubble generated at the outlet of the bubble Check the diaphragm is broken, check the clamp is locked, especially the inlet pipe clamps outflow from the air outlet Check the diaphragm rupture, Check if the diaphragm and the inner and outer cleats pinch the valve on the shaft to rattle
Introduction
Holter ECG Monitoring Systems adopt 12-lead system of international standard, which can continuously record ECG waveform for 24-hour and analyze ECG waveform by the PC software. It is applicable for use in medical institution and community.
Analysis Software Function
1.The rate of checking RR wave up to 99.9%, which increased the accuracy of analysis without losing wave.
2.AI histogram function which can directly distinguish various abnormal ECG which can analyze faster.
3. Dynamic ECG [Channel Correct" function, which can correct mistakenly wearing that makes the analysis more accurate.
4.Lorenz and Demix analysis function, which can analyze more faster, more accurately. Single medical case can be completely analyzed in 10 min, which can reduce the physician`s work.
5.ST can be displayed in many kinds of form, which ensures that analyzing ST- Trends Diagram comprehensively, observing the whole or partial ST variety to analyze the specific area of myocardial ischemia.
6.Atrial fibrillation function can be recognized automatically and can distinguish atrial fibrillation case, give advice and generate analysis report .
7.Unique Cardiac Fatigue Index function, which can judge index of Cardiac Fatigue .High-risk groups can be found and early intervention treatment can be taken by the index, which can effectively judge the heart age and predict SCD (Sudden Cardiac Death).
8. P-wave analysis function, which can check cardiac arrhythmia (such as AVB).
9.According to the requirement of patients, options can be selected freely while printing report, which can save physician `s time
10. ECG can be printed by various forms according to the user`s requirement.
11.Pacemaker analysis function, which can analyze different pacemakers(such as AAI,VVI,DDD).
12.The comprehensive analysis system of stand-alone version with network version ,users can freely select any model.
13.Wire and wireless simultaneously transfer mode ,which reduce complicated performance.
14. Dynamic ECG and static ECG analysis system ,which reduced complex operations.
15. Time Domain and Frequency Domain function on HRV module can reflect the moderation effect of sympathetic and parasympathetic to the heart rate.
16.HRT function can predict myocardial infarction which has clinical value.
17.ST function which can check the exact time and length of myocardial ischemia in 24 hours.
