The start-up procedure of Roots pump is the same as the disassembly and assembly instructions

 Onegt If the Roots pump is not started according to the correct startup procedure, even if the installation quality is good, the equipment cannot operate normally. So if you want it to start up and put into use normally, both the installation and operation methods must be very correct. And now we will explain to you how to carry out the correct startup program of the device, in order to help you control the device well and put it into use

(1) Open the inlet valve and adjust the water volume to an appropriate level. At this time, due to the suction effect of the previous stage pump, the gas in the system being pumped is pumped through the Roots pump. Due to the pressure difference, it produces rotation. When this phenomenon weakens with the decrease of pressure in the system, the Roots pump stops rotating(2) When the pressure in the system reaches the allowable starting and working pressure of the Roots pump, start it step by step. After starting the equipment, pay attention to the temperature rise and current situation of the pump. If overheating or high current is found, stop the Roots pump and check the cause. It is not allowed to stop the previous stage pump (oil-free vacuum pump) while the Roots pump is workingTherefore, in addition to conducting a trial run before starting the LC Roots pump, everyone should strictly follow the correct startup procedure to ensure a smooth start of the equipment. At the same time, it is also reminded that once abnormal phenomena are found during the operation of the equipment, the pump should be stopped for maintenance in a timely manner, and should not be ignored, as this can easily lead to major dangers

 II The disassembly and assembly instructions for Roots pumps should be noted. When disassembling Roots pumps, one should pay attention to their own operating behavior, otherwise it is easy to damage the pump body during disassembly and assembly, and even cause the equipment to be unusable. Therefore, the following are some instructions and requirements for disassembly and assembly operations to avoid errors during operation

Before disassembly, measure and record the clearances between each part of the rotor(2) Try to avoid hitting with a heavy hammer, and the removed parts should not be damaged and kept properly(3) Record in detail the reasons and usage of the parts that need to be replaced(4) Before reassembling the Roots pump, all components must be cleaned thoroughly and the brush must be polished(5) The static sealing surface without sealing gasket or sealing ring should be sealed with silicone paint, and the rubber seal used for static sealing should be coated with vacuum cock grease(6) Adjust the clearances of each part of the rotor according to the clearance listAfter all are installed, a leak detection must be carried outAfter reassembly, a trial run and performance test must be conducted, and the Roots pump can only be installed and used after it is functioning properly
