Three screw pump installation need to pay attention to what?

Three screw pump installation need to pay attention to what? Screw pump is a new type of liquid conveying machinery, with a simple structure, safe and reliable work, easy maintenance, liquid continuous average, the pressure is not chaotic and other advantages. How to install screw pump? First, the installation of screw pump Prepared screw pump installation of preparatory work Contents: (1) Check the screw pump motor to ensure that there is no damage during transport and handling (2) Check the tools and lifting machinery, and check the basis of the machine, Three screw pump installation requirements 1. Three screw pump check before installation of the oil seal is good, and check the pump during transport is damaged, the hand rolling coupling there is no card strength phenomenon, if any, should be disassembled pump cleaning , Repair and correction 2. Three screw pump installation of the pump into the oil and oil drain pipe, the diameter of not less than the pump inlet and drain diameter, the inlet pipe must not be too long, elbow not too much, otherwise it will affect Pump working status 3 When there are more than two three-screw pump installed in a unified pipeline, in order to facilitate the pump start, the pump must be installed in the exhaust pipe check valve. For standby pumps that deliver viscous oils (such as heavy oil) at higher temperatures (above 60 ° C), a hot spare pump must be used or the pump will start to run at low temperatures causing overload or damage to the pump. Installation specifications In addition to the installation of screw pump shall be implemented in accordance with the provisions of the first chapter of this chapter should still meet the following requirements: 1, the pump should not be in the case of liquid-free or full closure of the outlet valve to start pumping fluid should be filled before the start of delivery ; 2, conveying liquid temperature is higher than 60 ℃, should be preheated according to the delineation of equipment technical documents; 3, test run fashion should check the safety valve is agile and reliable.
