What principles should be followed for the installation of slurry pumps? The slurry pump is a horizontal, vertical medium-shaped slurry pump with double-cage shell structure.The pump body and pump cover have replaceable metal linings. The lining is made of high chrome wear-resistant alloy material. The lining can be used until it is worn, extending the maintenance cycle and reducing operating costs.The outlet direction of the pump can be rotated and installed at 8 angles.Slurry pumps (slurry pump accessories) can be widely used in mining industries, and transport slurry containing abrasive solid particles in the power, metallurgy, coal, environmental protection and other industries.Such as slurry transportation in metallurgical ore dressing plants, hydraulic ash removal in thermal power plants, coal slurry and heavy media transportation in coal washing plants, dredging river channels, river silting, etc.In the chemical industry, slurry pumps can also transport some corrosive slurries containing crystals.Of course, in different industries, the role of slurry pumps play differently and their working principles are different.The installation of a slurry pump is a complex task, which requires comprehensive consideration of the slurry pump and the on-site situation. The size of the slurry pump itself must meet the standard requirements, and secondly, the on-site working conditions must also meet the installation requirements.(1) Inspection before installation The slurry pump has been inspected and tested before leaving the factory. In order to ensure that it is in a good working condition, it must be installed correctly.Before installation, you should first check whether the model and parameters of the equipment are correct, whether the parts are complete and complete, and whether the technical information and quality proofs carried randomly are complete.After verification, you should read the relevant technical information in detail and master the relevant technical requirements and operating instructions. Only then can the slurry pump be installed. Do not operate blindly.(2) Configuration and requirements of the inlet and outlet pipe section of the slurry pump ① Suction pipeline Suction pipe diameter: The suction pipe diameter should be the same as the inlet diameter of the slurry pump or slightly larger than the inlet diameter of the pump. The principle is to avoid cavitation caused by the slurry pump, and the slurry cannot be deposited in the pipeline.Suction gate valve: To facilitate the maintenance of the slurry pump, a suction gate valve should be installed, with its diameter the same as the diameter of the suction pipe.A telescopic link should be installed between the suction port of the slurry pump and the suction pipe to disassemble and install the slurry pump.② Exhaust pipeline　　Draining pipe diameter: The discharge pipe diameter is related to the properties of the slurry and the settlement flow rate. Generally speaking, the discharge pipe diameter is equal to or slightly larger than the outlet diameter of the slurry pump.Outlet gate valve: The outlet gate valve should have the same diameter as the discharge pipe.Pressure gauge: located on the straight pipe section between the slurry pump outlet and the valve.③Precautions for pump pipeline configuration: When using a valve to adjust the flow, the regulating valve should be installed at the pump outlet. It is not allowed to be adjusted with a valve on the inlet pipeline to avoid cavitation.(4) Pipeline configuration and requirements for shaft sealing water and cooling water The shaft sealing part where the mechanical sealing pump is installed has two exposed pipe joints. The side of the pressure gauge is the water inlet and the other side is the water outlet.The grease-lubricated bracket is free of cooling water.When lubrication of fillers is used, no shaft sealing water is added.

Can mechanical seals be used in slurry pumps for easily crystallized ore pulp?

It is recommended to use: expeller + packing seal: the expeller generates centrifugal force to block particles from entering the sealing area, the packing seal is low-cost and resistant to a certain amount of crystallization (regular maintenance is required).

Pumps for Quartz Sand_Rubber-Lined Slurry Pumps in Quartz Sand Beneficiation Equipment

Quartz sand beneficiation focuses primarily on purification, a technically challenging separation process aimed at removing minor or trace impurities from quartz sand to produce refined quartz sand or high-purity quartz sand. Common purification techniques employed domestically and internationally include: Washing, Classification & Desliming, Scrubbing, Magnetic Separation, Flotation, Acid Leaching, and Microbial Leaching.

The Ultimate Guide to Slurry Pumps: Types and Applications

Selecting the right slurry pump ensures efficient performance, especially when dealing with high-volume and abrasive slurries. The ideal pump depends on the application, material compatibility, and operational demands.

Diagnosis Methods for Cavitation in Warman Slurry Pumps

The following techniques can be used to determine whether cavitation is occurring in a slurry pump:a. Ultrasonic testing b. External noise monitoring c. Vibration analysis

Horizontal Slurry Pumps: Principles & Application

Because they offer longevity, efficiency, and adaptability, horizontal slurry pumps are crucial for sectors handling abrasive slurries. Knowing their values, applications, and maintenance needs allows businesses to maximize performance and reduce expenses.

Commissioning of Slurry pumps

Slurry pump commissioning must be strictly conducted in accordance with established procedures: Prior to startup, first activate the shaft seal water and adjust it to the specified pressure. Fully open the inlet valve. For non-backflow pumps, water must be injected. After opening the outlet valve to one-quarter, initiate startup; During operation, monitor flow rate, head, current, vibration, and bearing temperature (temperature rise ≤35°C, maximum ≤75°C). Mechanical seal leakage should be ≤3-5 ml/h. Before stopping the pump, flush with clean water for 30 minutes, close the outlet valve first, then shut down the pump, and finally close the shaft seal water and inlet valve. It is strictly prohibited to fully open the outlet valve when stopping the pump to prevent water hammer. Throughout the entire trial operation process, ensure that parameters remain stable, avoid cavitation and overload conditions, to ensure safe operation of the equipment.

Common Problems During Feeding of Slurry Pumps

When a slurry pump malfunctions during operation, the first step is to identify the cause of the failure. Corresponding repair measures should be taken based on the characteristics of the failure and maintenance experience.

Aspects to Pay Attention to for Slurry Pumps to Run Stably and Efficiently in Series

The advantage of slurry pumps in series is that multiple pumps are arranged in one pump station, which is convenient for installation, maintenance, operation and management, with a total low cost, it can realize overall automatic management. The following aspects should be noted when selecting slurry pumps in series:

The Hazards to Slurry Pumps if Running in a Low Flow Area for a Long Time

The slurry pumps we often use are a type of centrifugal pump. It mainly drives the slurry mixture to rotate through the high-speed rotating impeller blades, and throws out the slurry to achieve the purpose of transportation.
