In order for the industrial slurry pump to fully play its role, we need to understand the working principle of the industrial slurry pump: https://www.lzzgmachine.com/products/supporting-equipment/slurry-pump.html Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy to leave the outer edge of the impeller at a high speed and enter the volute pump shell. In the volute pump case, the Fluid is slowed down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy. At last, it flows into the discharge pipe and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. LZZG slurry pump pe

For many users who use dewatering screens , the quality of the sieve plates is very important, because the quality of the sieve plates directly affects the production volume, which reduces the economic benefits. Although it has been said that if the sieve plates are seriously damaged, replace them with a new one. However, after all, replacing the sieve plate is a very troublesome and unnecessary thing, so no one wants to continue to do so. However, in recent years, a new dewatering sieve plate appeared in the mining equipment parts market, called polyurethane dewatering sieve plate. The sieve plate of the dewatering sieve is related to the screening effect and the dewatering effect, so the importance is self-evident, so it is necessary to choose the quality when purchasing the dewatering sieve. 1. The customer asks: How long is the service life of the sieve plate of the polyurethane dewatering sieve? How can I reduce the frequency of sieve plate replacement? Under normal circum

How does trommel screen work? The trommel screen is connected by the motor through the reducer and the roller device through the coupling and drives the roller device to rotate about its axis. Through the variable speed deceleration system, the screening cylinder is rotated at a certain rotation speed, and the material is separated from the top to the bottom through the screening cylinder, the fine material is discharged from the lower part of the front end of the drum screen, and the coarse material is discharged from the lower end of the screening cylinder. Due to the turning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged. During the use of the drum screen, the operation is slow and uniform, the impact vibration is small, the work is stable, the installation is simple, and no special foundation is needed. The installation angle is small and it is not easy to block. It can be placed direct

The vibrating screen bearing works under heavy load and large centrifugal force, so the heating phenomenon is usually obvious. Normally, the vibrating screen empty car test 4h, the bearing temperature should be maintained at 35 ~ 60 ° C. If the bearing temperature is high, it may be caused by the following reasons. (1) Unreasonable bearing model selection If the vibrating screen is used frequently, the bearings in the exciter are frequently overheated and there is no obvious improvement after refueling. It is very likely that the bearing model is unreasonable. The main reason for this is that the bearing radial clearance is too small. The bearing on the vibrating screen has a high operating frequency and a very large load carrying capacity. At the same time, the load is a variable load. If the radial clearance of the bearing is too small, there is no way to withstand high frequency and large loads, so it is necessary to select a large clearance bearing when selecting. (2) lack
