the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　The mixing impeller and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothingRenosa,　　 Damage of mechanical seal the material of mechanical seal is generally Cr or L, not flexible and vulnerable. The installation of mechanical seal is that the static ring is fixed outside, and the moving ring is fixed with the pump shaft. When the slurry pump reverses and the impeller retreats　　The Tao part also consumes part of it.Kholargos,　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.

　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　 WQ submersible sewage pump adopts a unique single or double vane impeller structure,RenosaVertical multistage centrifugal pipeline pump, which greatly improves the sewage passing capacity, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps mayFocus on Development,　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.

　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.Promise and keep promise,　　Some impurities will entangle the impeller, so generally, the open impeller will be used so there is no need to worry about getting stuck in the process of transporting sewage.　　 Realize centralized management. In the application of multiple fire pumps, the deployment of fire pumps may be decentralized,RenosaSubmersible non clogging sewage pump, and the working environment of fire pumps is often complex, so it is very difficult to adopt manual management. cf fire control cabinet can realize centralized management of multiple fire pumps, with operation　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.Renosa,RenosaWQ submersible pump parameters,　　Stability and reliability of seals between pump bodies.　　Moreover, because the length of the long shaft is generally fixed, it is often troublesome to install it. Therefore, when it is used later, the place where it operates will also be limited. If the equipment will　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simple
