We have already introduced a lot of slurry pumps before, such as: Can slurry pumps achieve the purpose of energy saving and consumption reduction?If the slurry pump sleeve is worn to this level, it should be replaced.I believe everyone has a certain understanding of it, but you may not know much about its oil drainage methods and steps.　　1. If you want to empty all the oil in the slurry pump box, you can unscrew the oil drain screw plug at the bottom of the box to discharge the oil.2. When the pump discharges oil, the liquid level height should not exceed 30 mm from the top plate of the oil tank to ensure lubrication and cooling of the bearings in the pump.When the volume of the jack working chamber is too large, an additional fuel tank is required.After draining the oil, please make sure the liquid level is very low and the height is not less than 100mm to avoid oil absorption.3. After the speed-regulating slurry pump starts to run for 500 hours, the engine oil should be replaced, and the oil tank and filter should be cleaned. The oil quality should be tested through visual inspection and laboratory tests.When the quality of the engine oil decreases, the engine oil should be replaced in time.Make sure to clean the oil tank and oil filter at the same time, and if there is metal chips or water in the oil, find out the cause and troubleshoot the problem.4. In a short period of time when the liquid level drops, the bearing will be lubricated with attached oil and splash oil from the plunger spring.The oil filter in the tank and the oil filter under the pump are made of 230 mesh/inch copper wire mesh and are filtered, and the mesh should be cleaned regularly to prevent clogging.During use, the oil temperature in the fuel tank shall not exceed 60 C, and appropriate measures shall be taken to cool if necessary.

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.

The methods for adjustment the flowrate of slurry pumps

The flowrate adjustment method of slurry pump can be selected in various ways according to different needs and occasions. The following are some common flowrate adjustment methods:

Five Main Reasons for the Blockage of Slurry Pumps

Uneven medium density is one of the reasons for the blockage of slurry pumps. When the medium density is uneven, the pump may vibrate at the beginning of the startup, but this vibration usually disappears when the pump starts normally.
