Self-priming magnetic pump switch sequence and precautions small manual

Self-priming magnetic pump switch is to use an important step, the boot and shutdown sequence is very important, everyone in the use of self-priming magnetic pump should be strictly in accordance with the correct sequence of the switch, To pay attention to and pay attention to the situation in order to better use! So what should be done? Many people are wanting to understand this problem, Xiaobian today for everyone to bring some of the precautions on the proper use of magnetic pump, do not understand Just hurry to see friends. Note the use of self-priming magnetic pump First, the correct sequence of the power switch Self-priming magnetic pump must be kept in the pump before starting boot full of water. Fully open the inlet valve at startup, close the outlet valve, and start the motor until the motor slowly opens the outlet valve to the desired flow or pressure after running at normal speed. NOTE: Do not allow the pump to operate for extended periods of time with the outlet valve not open and with the small flow rate specified by the pump. Pump operation prohibits the use of imported valves to regulate flow, the maximum opening of the inlet valve must be maintained. Self-priming magnetic pump in the first boot, the coupling pump can remove the coupling part of the jogging motor test steering. Or do not split the coupling, test the motor steering in the pump water. Motor and pump direct connection, but also must ensure that when the pump water test steering. It is forbidden to directly turn on the motor to test the steering when there is no water in the pump. The self-priming magnetic pump closes the outlet valve at shutdown, then turns off the motor, and the inlet valve installed closes after the motor stalls to ensure that the pump reservoir has water diversion (check valve not closed). In the northern freezing period (or the ambient temperature is below the freezing temperature of the liquid), the pump water must be drained to prevent the self-priming magnetic pump from cracking. Long-term deactivation, the need to drain the pump water, if necessary, disassemble self-priming magnetic pump, cleaning parts for rust treatment, safekeeping. Two: Other considerations Magnetic pump a little more, but in the course of operation, should pay attention to the following points: 1. To prevent particles from entering (1) does not allow ferromagnetic impurities, particles into the magnetic clutch and bearing friction. (2) After conveying the easily crystallized or precipitated medium, it should be rinsed promptly (after the pump is stopped, pour water into the pump chamber and discharge clean after running 1min) to ensure the service life of the sliding bearing. (3) When transporting media containing solid particles, filter at the inlet of the pump tube. 2. To prevent demagnetization (1) Magnetic moment can not be designed too small. (2) It should be run under the specified temperature, the medium temperature is strictly not allowed. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annulus area so as to alarm or stop when the temperature exceeds the limit. 3. To prevent dry friction (1) Do not idle. (2) It is forbidden to use the medium to empty. (3) in the case of the outlet valve is closed, the pump continuous operation time shall not exceed 2min, in case the magnetic actuator overheat listen to Xiaobian these introduction is not a little gain? If you usually do not notice these problems now Quickly amend it, so as to better use of magnetic pump products, to avoid unnecessary failure to extend the life of the magnetic pump.
