Three-cylinder electric pump properly installed and use the method

[Asia pump network hearing] Three-cylinder electric pump pressure medium is generally water at room temperature, can also use emulsion, rust-proof water and neutral viscosity similar to water and oil. Coupled with cleaning accessories, the machine can also be used as a washing machine. Now to introduce the next three-cylinder electric pump properly installed and used. Three-cylinder electric pump three-cylinder electric pump installation and use of a method of installation 1. Installation of handrails. 2. Install the motor starter and power lines. (See Figure 6) 3. Install the return pressure relief valve (this part is shipped from the main unit to remove the individual package). Installation position shown in Figure 5, the pieces from the anti-clockwise nut and relief valve tee outlet (40MPa above the specifications directly with the pump head outlet) connection, the junction should be sealed with copper pads. 4. Install the pressure gauge. 5. Use a high-pressure hose to connect the pressure-test line to the non-return pressure relief valve. The connection should be sealed with a copper pad. 6. Install the inlet pipe. Second, the use of methods 1. Preparation before use a. Gearbox plus enough oil, so that the oil level indicator line position, the lubricating oil for N46 mechanical oil (or 40 # mechanical oil). b. Check each thread connection for looseness. c. Check the motor and starter insulation meets the requirements of electrical procedures. For safe use of electricity, the whole machine must be reliably grounded. d. Set up a clean water reservoir and ensure adequate water supply. The inlet pipe filter into the reservoir, pay attention to the filter shall not be exposed to the water. 2. Operation Procedure (1) Operation below 31.5MPa (with relief valve) a. Open the relief valve handwheel and relief valve adjustment nut. b. Start the motor, run at atmospheric pressure for 5 minutes, check the pump is running properly. If there is no abnormal sound, and the pump discharge medium no significant fluctuations, at this time can be step-up operation. c. Close the pressure relief valve handwheel and slowly adjust the pressure relief valve to slowly increase the pressure of the system. After reaching the test pressure, loosen the relief valve adjusting nut to remove the discharge pressure of the pump, and then stop the machine (if the user needs, stop the machine) At this moment, the pressure test pipeline is under automatic pressure keeping status. d. After the pressure test is finished, open the relief valve handwheel and remove the pressure of the pressure test pipeline. e. If it is used for constant pressure output medium, close the relief valve handwheel, adjust the relief valve to reach the test pressure and lock the locknut. (2) 40MPa or more specifications (without relief valve) a. Open the relief valve handwheel. b. Start the motor, run at atmospheric pressure for 5 minutes, check the pump is running properly. If there is no abnormal sound, and the pump discharge medium no significant fluctuations, at this time can be step-up operation. c. Shutdown, turn off the pressure relief valve handwheel, jog motor booster up to the test pressure and shut down, at this time, the pressure test tube is in autoclave state. d. After the pressure test is finished, open the relief valve handwheel and remove the pressure in the pressure test pipeline and pump. 3. Precautions during use (1) For specifications below 31.5MPa (with relief valve) a. If the pressure gauge pointer swings too much during the pressurization process, the volume of the user's test pressure piece is too small. This It is best to connect a pressure vessel of sufficient capacity (which should comply with relevant national standards) or other appropriate accumulators in the system. B. Boost can be carried out with a pre-set pressure jog booster. c. If accidentally overpressure, can open the pressure relief valve hand wheel, remove part of the pressure and then pressure. d. The test pressure shall not exceed the rated working pressure of the pump. (2) For 40MPa or more specifications (without relief valve) a. If the volume of the test piece is larger, it can be continuously operated and boosted until it is close to the test pressure. During operation should pay close attention to system pressure, to avoid accidental overpressure. B. If accidentally overpressure, open the relief valve hand wheel, remove some of the pressure and then pressure. c. The test pressure shall not exceed the rated working pressure of the pump.
