Increasingly fierce market competition, all enterprises to maintain production management, improve quality and reduce consumption, high yield and efficiency has become an important goal. The installation and maintenance of various types of beverage pumps as the source of pipeline transportation have become the key factors that affect the efficiency of the entire line. Therefore, a comprehensive understanding of the pump installation and maintenance, for the stability of production efficiency has an extremely important role. Following the installation and maintenance of beverage pumps and local improvements do briefly explain. First, the installation and maintenance of beverage pump body and pipeline 1, the first is the basic installation, should pay attention to the following questions; (1) the surface of the base must be installed, clean and can withstand the corresponding load; (2) (3) For vertically mounted pumps, the anchor bolts must have sufficient strength; (4) The motor must be above the water pump if it is mounted vertically; (5) When it is fixed to the wall , Pay attention to find positive, right; 2, followed by the installation of the pipeline. During the installation of the pump, the selection of the pipeline, the ratio of the pipe diameter and the choice of the valve position have a direct impact on the running effect of the pump. Therefore, when installing the pipeline, the following should be done: (1) Do not use a water pump (2) reasonable use of torque, auxiliary materials and tools to avoid excessive force and angle deviation; (3) absolutely avoid pump distortion, CN pump coupling must be centered; (4) (5) Before installation, be sure to remove the pump inlet and outlet sealing plastic paper and plastic cap on the pipe; (6) The inlet pipe Must be airtight, and can not have a place of gas, or to add exhaust valve; (7) considering the cavitation, inlet pipelines to avoid large resistance elbow and valve; (8) the resistance of the system shall not be greater than the pump Head; (9) The nominal diameter of the pipe is greater than or equal to the connection size of the pump pipe; (10) Install the cut-off valve on the inlet pipelines and ensure that the pump is always fully open during the work, installed on the outlet pipe cut- . 3, after the installation of beverage pumps, operation and maintenance should also pay attention to several issues, as follows: (1) pump conditions must be consistent with the pump operation adjustment (pressure, temperature and media, etc.); (2) Of the substance, check carefully before starting the pump; (3) exhaust before starting the pump; (4) when the system is filled with water or exhaust gas, the pump can also be filled with water and exhaust gas; (5) Or long-term do not have to use hand crank to confirm its flexibility; (6) is strictly prohibited dry turn! (7) For the vertical installation of the pump, there must be a seal leakage discharge point, when there is a leak, to promptly check the mechanical seal and replace if necessary; (8) adjust the outlet valve to ensure the pump operating point, to prevent overload; (9) Do not close the valve to run the pump for more than 30 seconds; (10) Under normal conditions of use, 15,000 hours to 20,000 hours to replace the bearing; (11) For long-term outdoor use, 5,000 hours of operation to be replaced bearings; 1,500 hours to lubricate the V-ring. In the structure of the beverage pump, the mechanical seal is the most accurate and the most sophisticated part of the installation. If the mechanical seal is improperly handled during installation, it will affect the service life of the seal and may cause the beverage pump to suddenly leak during operation, thereby affecting the production efficiency of the entire line. Before installing the mechanical seal, check the static and dynamic ring contact surface for any damage or cracks, and clean the surface of the static and dynamic ring with a soft, clean cloth. When installing, first remove the scale and stains on the bottom and side of the static ring installation groove, and then put the static ring into the installation groove smoothly to ensure full contact between the static ring and the bottom of the groove to avoid the axial rocking of the static ring. Pay special attention to keep the surface of the static ring at any time during the cleaning process, and finally move the ring slowly into the ring, gently rotate the ring around and observe the static and dynamic ring surface contact, when the ring is confirmed close contact, the impeller into the lock Tighten the bolt to complete the mechanical seal installation.
