Environmental protection equipment maintenance _ Luoyang Yu Quan Environmental (certified) _ Shangqiu environmental protection equipment provided by the Luoyang Yu Quan sewage treatment Limited. Luoyang Yu Quan Sewage Treatment Co., Ltd. (www.yuquankj.net) is specialized in "environmental protection equipment, sewage treatment equipment, industrial wastewater treatment equipment, grille decontamination machine" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Chang Chih-feng. Selection Considerations sewage treatment dosing device: a user when dosing device selection, the first dosing solution based on the amount of system requirements specifications to affirm the choice, according to dosing, the situation is certainly dosing, dosing sure way 2, according to the demand dosing device components selected materials (stainless steel, carbon steel, non-metallic materials, glass and steel), metering pump model (diaphragm, piston) or provide additional agents parameters (name, concentration, temperature, density, to my company viscosity, corrosion, etc.) 2, dosing equipment installation control cabinet is mounted on the air from a high of about 50--250mm wide metal frame. Distance control cabinet should be installed in conjunction 4.5 room. Dosing point to sampling point is about 8 - 10 meters, suitable for rapid conditioning systems on large time delay conditioning systems dosing may not be limited to the sampling point distance Environmental Protection Equipment Engineering , but may segment is appropriate. Sensors monitor the rapid conditioning system should be as close to the sampling point farming and environmental protection equipment, the sampling tube within about 5--8mm, a length of about 2--4 meters municipal environmental protection equipment, large delay conditioning system for this entry pleading no severe. Upper and lower limit alarm, inverter shortcomings best alarm installed in the duty room operating personnel. Precautions sewage treatment equipment centrifugal pump: its facilities intact, start the motor. (When you start the motor staff and crew do not too close) in the case of the water valve is closed, the running time is generally no more than 2-3 minutes, too long the pump body fluid fever, could easily lead to accidents. Open the pressure gauge, and gradually open the water valve. At this point the outlet pressure gauge should be gradually reduced traffic gradually increased, the operating current gradually increased. Change the size of the outlet valve opening, adjustable outlet pressure and flow, ensure the unit is running in the high range. (Running between large and small flow point flow point). Note: Sewage treatment equipment centrifugal pump head is equal to the actual inlet pressure minus outlet pressure. As long as the pump pressure and flow in line with the design condition, the motor is not overloaded, then the hydraulic performance of the unit, no problem, can meet the requirements of the scene, it is a selection problem.
