Safe Operation - Solenoid Valve Installation Instructions: 1, read the product manual carefully before installation, check whether the product meets the requirements for use, remember the installation points, make preparations.
2. Check whether the parameters on the nameplate are consistent with the parameters of the selected product. The power supply voltage should meet the rated voltage and voltage fluctuation range: AC +10%~-15%, DC+10%~-10%. The coil component should not be disassembled at ordinary times. .
3. Before the solenoid valve is taken over, the pipeline is flushed with a pressure of 0.3 MPa to remove metal powder, seal material residue, and rust from the pipeline.
4, pay attention to the cleanliness of the media, if the media mixed with dirt, impurities, etc. prevent the normal operation of the solenoid valve, the pipe filter valve filter should be installed ≥ 60 mesh.
5, solenoid valve should not be installed in the lower part of the pipeline, installed in the discharge pipe of the container, pay attention not to lead from the bottom of the container, but should be installed on the bottom of the container slightly.
6, if the media will play a water hammer phenomenon, then you should choose to use the water hammer function of the solenoid valve or take appropriate precautions.
7. A steam trap should be installed on the inlet side of the steam solenoid valve, where the nozzle should be tilted.
8, solenoid valve is generally oriented, can not be installed, usually on the valve body with "→" indicate the direction of flow of the medium, the installation should be in accordance with the direction of the "→" instructions but the company may sometimes in the vacuum line or under special circumstances There will be proposals to reverse install.
9, installation position: general solenoid valve solenoid coil components should be upright, vertically installed in the level of the ground pipeline, if subject to space constraints or conditions must be set up by the side of the building like a sewer pipeline or inverted installation , please put forward when selecting the order. Some products have special regulations. Please follow the instructions.
10. When taking over, take care that the sealing material cannot be used excessively. If the thread is connected, the thread of the thread should be kept within the effective length and be chamfered with a guillotine at the half pitch of the end. Begin to wind the seal with 2 teeth from the end, otherwise the excess seal tape or adhesive will enter the electromagnetic The internal cavity of the valve caused an accident that prevented normal operation.
11. There should be some reserved space for the solenoid valve installation place for daily maintenance and regular maintenance.
12. When installing the valve body with a wrench or pipe wrench, and then screwing it on, do not apply force to the electromagnetic coil assembly to cause deformation, making it difficult for the solenoid valve to work normally.
13. In the case of insufficient pipe rigidity or water hammer phenomenon, please attach the valve before and after the pipe is fixed with the bracket.
14. When using in a frozen place, protect the pipeline with a thermal insulation material or install a heater on the pipeline.
15, to confirm that the solenoid valve and its connection with the takeover whether there is leakage.
16, check the connection of the coil lead, especially the three lead wire occasions.
17. Electrical components connected to solenoid valves, such as relays, switches, and contactors. The contact should not vibrate when opening the valve, otherwise the work will not be reliable and affect the life of the solenoid valve.
18, the electrical circuit to access the appropriate insurance line, as the electrical circuit protection.
APPLICATION FEATURES
1. Environment:The bearing is located in the lower part of the chassis, normally working in a dusty and mud splash environment, so it is with high requirement of bearing sealing performance. Working in outside, from low temperature -40 ℃ to high temperature 100℃;
2. Rotating speed: Highest is 3000rpm;
3. Loading: Besides to bear the weight of the main rotating axis, also need to bear the uncertain axial load;
4. Eccentric Oblique angle:Bearing is used with propeller shaft(or drive shaft), need consider to compensate the installation error of the shaft, and the displacement caused by the engine vibration and frame deformation, so the oblique angle of bearing are key factor to be paid attention during bearing design.
