Three screw pump during use Notes: (1) pump intake and exhaust pipe diameter of not less than the pump inlet and outlet diameter, the inlet pipe short in order to reduce unnecessary losses (such as elbows, etc.), the pump installation height should Ensure that the pump does not exceed the allowable suction vacuum height. (2) The pipe should be pipe rack, the pump is not allowed to withstand the load of the pipeline. (3) Before installation, it is necessary to clean up the suction and discharge pipelines, especially the welding slag of the suction pipe must be completely removed to avoid biting into the pump. (4) suction pipe should be installed filters, the filter is 40-80 mesh, the effective filtration area should be larger than the pump suction diameter 20-30 times. (5) pump inlet and outlet connections vacuum and pressure gauge, in order to observe the working status of the pump. (6) If more than two pumps are connected in parallel on the same pipe, a check valve must be installed at the pump outlet to ensure the normal operation of the pump. (7) The location of the installation of the pump should be spacious, easy maintenance. (8) The unit is placed on the foundation buried bolt, find the positive and then tighten the anchor bolt. (9) After connecting the pipe and determining the motor steering coupling, the tolerance of the coaxiality of the coupling is 0.1mm, and the tolerance of the clearance of the two coupling ends is 2mm. (10) 3-4 hours after the unit running for the final inspection, if no adverse phenomena, then that the installation of qualified. (11) The heat pump is connected with the pipe valve 1, 2 on the back of the pump inlet. Before starting the pump, the valve 1 and valve 2 should be fully opened and the pump unit can be opened only when the steam (liquid) for insulation is applied and reaches the specified holding temperature. If the work is not required for the insulation of steam (liquid), the valve can be closed 1, pay attention to the exhaust valve 2 can not be closed. (12) Import and export of pipes and pumps connected to the pump, the flange must be clean, impurities are not prohibited, slag residue tube
