In the use of slide valve pumps, will encounter greater vibration and noise problems, both shorten the life of the pump, but also pollute the environment. So when the pump encountered such a problem, how to solve it? The following is a slide valve pump vibration and noise problems introduced. Sliding valve pump vibration and noise solutions to the problem 1. Overall structural aspects. Slide valve pump can be designed to be vertical structure or horizontal structure. From the development trend, horizontal (ie, inclined) structure is more reasonable. Because of its compact structure, low center of gravity, is conducive to reducing vibration. Balancing The balance wheel is usually balanced with the balance wheel by adding an unbalanced weight to the pulley to balance the inertial forces of the eccentric wheel and the slide valve. Dynamic analysis and test of the pump spool motion system shows that the movement of the spool stem is a very important factor that influences the vibration of the pump, for example, after the pump has been balanced with the wheel. 1 Vertical H-150A pump due to the movement of the valve stem generated by the vibration value of 2/3 of the total vibration value; horizontal H-150 pump accounted for 9/10. Through the analysis and calculation, and then balance the wheel plus the weight method to balance the inertia force of the spool stem.It has been proved that this kind of effective damping method. 3. Mechanical damping device. For high-speed pumps and large pumps, in addition to the use of balanced measures, but also the method of mechanical damping can be used to reduce vibration. For example, a rubber shock absorber may be used to mount the shock absorber on the base of the pump to absorb vibration by rubber. 4. The number of pump cylinder reasonable choice and layout. Slide valve pump has a single cylinder, twin cylinder and three cylinder and other structures. For single-cylinder, twin-cylinder and other structures such as three-cylinder pumps, pumps are required to balance the balance weight to balance the operation of inertia and inertia moment. An unequal length three-cylinder structure solves the vibration problem of the slide valve pump from the structural principle.
