1. When installing, please pay attention to the arrow on the valve body should be consistent with the flow direction of the medium. Do not install in places where there is direct dripping or splashing. Asphalt insulation pump should be vertical Install up.
2, RCB Heat Jacket Asphalt/Bitumen Gear Pump should ensure that the power supply voltage is within 15%-10% fluctuation range of the rated voltage.
3. After the asphalt insulation pump is installed, there must be no reverse pressure difference in the pipeline. It needs to be powered on several times to make it suitable for use.
4. The asphalt insulation pump should be thoroughly cleaned before installation. The medium to be passed should be free of impurities. Install the filter in front of the valve.
5. When a fault or cleaning occurs, a bypass device should be installed to ensure that the system continues to operate.
Process analysis of RCB asphalt insulation pump before aging of workpiece
The effect of vibration aging depends on the choice of process for vibration aging. The metallurgical butterfly valve body is a structural part cast from casting. The asphalt heat preservation pump has a complicated shape, relatively large rigidity, many convex and concave surfaces, uneven wall thickness, large residual stress and complicated distribution. There have been many shortcomings in the process of using natural aging. Since the company began to adopt the vibration aging process in 2005, it has made great progress in product quality and production efficiency. Years of production practice experience shows that: due to the complexity of the process of vibration aging, the process analysis of the box parts must be carried out before the vibration, and the vibration parameters should be optimized to improve the vibration aging effect.
According to the process specification of vibration failure, the asphalt insulation pump should analyze the process before the aging of the workpiece to save energy and work time. Firstly, according to the material and structure of the workpiece, the process form and process of the blank manufacturing, the distribution of the residual stress field of the box, the dimensional accuracy requirements, the working load, the possible failure causes and other factors should be analyzed, and then the vibration is decided. Time-sensitive process route and timely focus.
Brief description of the specification of RCB Heat Jacketed Asphalt/Bitumen Pump
When using asphalt insulation pump, we must establish strict technical maintenance specifications. The fuel filter works for 100 hours, and the fuel tank works for 500 hours. If the filter breakage effect is found to be replaced in time, it should not be removed and DC is used. Oil supply. The parts should be disassembled and inspected once under normal working conditions for 500 hours. When disassembling and inspecting the asphalt heat preservation pump, ensure that the place, hands, tools and cleaning oil are clean to avoid contamination of the parts. Do not tamper with the disassembly during the disassembly operation. Do not arbitrarily pile up during cleaning. Do not wash with other non-parts to avoid bumps and abrasions. Do not arbitrarily change the assembly position during assembly to achieve certain objectives that do not meet the machine's working requirements. When installing the oil valve seat and the oil nozzle tight cap, tighten the torque according to the specified torque to ensure the technical state of the injector and fuel injection pump after assembly. Understand the structural characteristics and working principle of the coupling parts, strengthen and improve the maintenance and operation of the pair of parts, do not adjust at will when there is no fault, do not disassemble during maintenance and maintenance, do not mess with the maintenance inspection, cleaning and maintenance Do not mess with the bumps, assembly adjustments do not mess up and mess, all according to the technical requirements of asphalt insulation pump specifications, in order to extend the service life of asphalt insulation pump.
