Rotary blower: commissioning after installation

After the rotary blower device, the trial operation is required. In fact, after the fan is repaired, it is also required to carry out an empty load test operation. What is the empty load test operation: during the test operation, time should be paid attention to the splashing condition of the lubricating oil on the pipe. if it is too much or too little, the oil quantity should be adjusted immediately.

Rotary Blower: Introduction of Rotary Blower

The working principle of 1. rotary blower The blower runs eccentrically on the eccentric position of the rotor in the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress and discharge air. During operation, the differential pressure of the blower is used to automatically deliver the lubricating fluid to the dripper and drip into the cylinder to reduce friction and noise, while also preventing the gas in the cylinder from flowing back.

How to solve the problem of Roots blower reverse damage

There are many reasons for the damage of Roots blower caused by reverse rotation. What are the reasons and solutions for the friction between the impeller of the Roots blower and the casing, impeller and gear? Remember not to run in reverse. During the test run of the Roots blower, please check the rotation of the Roots blower and make sure that there is no problem with the steering before installing the test run.

Roots vacuum pump: Roots vacuum pump unit ventilation process

Roots vacuum pumps are widely used in metallurgy, petrochemical, paper, food and electronics industries. In order to better use the Roots vacuum pump and give full play to its high efficiency performance, the following, Shandong Sanniu Machinery Group Co., Ltd. will be used before the ventilation of the knowledge to do a certain explanation: 1. Air flows from the air inlet to the Roots vacuum pump unit to form a convection blower. During this process, the doors and windows near the equipment remain closed, and air is forced to flow into the workshop through the doors and windows on the side of the air inlet. The air is ordered. It flows into the workshop from the air intake, flows through the workshop, and then leaves the workshop from the workshop.

Roots vacuum pump: detailed explanation of Roots vacuum pump selection considerations

Roots vacuum pump is a rough pump that uses liquid as the working medium and has been widely used in industry. In order to make the equipment play a better role, in addition to the preliminary work before selection, the following points should also be mastered: 1. The working pressure of Roots vacuum pump should meet the ultimate vacuum and working pressure requirements of vacuum equipment. 2. Correct selection of Roots vacuum pump operating point. Each pump has a certain working pressure scale, the working point of the pump should be selected within this range, and long-term operation under 10-8mmHg is not allowed.

Roots vacuum pump: Why add water to Roots vacuum pump

Roots vacuum pump is one of the commonly used vacuum pumps. In terms of generating vacuum and pumping air, we found that they are still relatively powerful in these aspects. In use, there are strict requirements for many of its operations, and only in this way can the efficiency of the pump be improved. Sometimes water is added to achieve a good suction effect. So, why do you want to do this?

Roots vacuum pump: Notes during the use of Roots vacuum pump

The working principle and performance characteristics of Roots vacuum pump: Roots pump and lobe pump are basically the same, but the rotor is Roots type. It can transport liquids with a viscosity of tens of thousands of centipoise. Roots vacuum pump is mainly composed of two counter-rotating rotors in the pump body and driven by a pair of synchronous gears. The rotor of the Roots vacuum pump meshes in the pump body, but there is a gap. The size of the gap mainly depends on the viscosity of the liquid, and the viscosity must be adjusted outside a certain range to increase the gap.
