Centrifugal mud pump

Centrifugal mud pump
we product Centrifugal mud pump,if you need Centrifugal mud pump,please contact us.
Basic construction the basic construction of centrifugal pump is a centrifugal pump is made up of six parts, respectively is: impeller, pump body, pump shaft, bearing, seal ring, stuffing box.
1, is the core part of a centrifugal pump impeller, its high speed output force, on the impeller blades and play a major role, the impeller through static balancing experiments before assembly. Impeller on the inside and outside for smooth surface to reduce friction loss of water.
2, the pump body also calls the pump shell, it is the body of the pump. Support fixed effect, and connected to install bearing bracket.
3, the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer.
4, bearing is set on the pump shaft support components of pump shaft, which has two kinds of rolling bearing and sliding bearing. Rolling bearing use butter as a lubricant oil is generally appropriate for two-thirds to three-quarters of the volume too much will be fever, too little and there was a noise and fever! Sliding bearing structure of centrifugal pump is using a transparent oil as lubricant, go to the oil level line. Too much oil to leak along the pump shaft and drift *, too little bearing overheating and burn out cause an accident! Bearing has the highest temperature in the process of pump working in 85 degrees generally run around 60 degrees, if the high will find reason (if there are impurities, oil is black, whether water) and processed in a timely manner!
5, sealing ring, also known as minus leakage ring. Import and pump impeller shell gap between in the cause of high water in the pump by means of this clearance flow to the low pressure area, affect the water yield of pump, efficiency! Clearance starts to cause the impeller and pump casing friction wear. In order to increase the flow resistance reducing internal leakage and delay the service life of the impeller and the pump shell, the pump casing and impeller around the foreign aid junction with sealing ring, sealing gap in between 0.25 ~ 1.10 mm is advisable.
6, stuffing box is mainly composed of filler, seal ring, packing, packing gland, water tubes. The role of the stuffing box is mainly in order to close the gap between pump casing and pump shaft, don't let the flow within the pump does not flow outside to not let outside air into the pump. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat to hold water to the water seal circle packing cooling! Keep the pump running. So in the process of pump run Tours of inspection to check the stuffing box is paying special attention to! Running about 600 hours will be carried out on the packing replacement. [editor this paragraph] the working principle of centrifugal pump Impeller is installed in the pump shell 2 and fastening on the pump shaft 3, pump shaft driven by the motor directly. Pump shell central suction pipe and a liquid inhalation 4 5 connection. Liquid by the bottom valve 6 and the suction pipe into the pump. Liquid on the pump casing outlet connected to the discharge line 9. Before starting the in centrifugal pump, pump shell filled with liquid to be delivered; After the start, start, by axis high-speed rotating impeller, the blade between the liquid must also along with the rotation. Under the action of centrifugal force, the liquid from the impeller center was thrown to the outer edge and gain energy, leaving the impeller outer edge at high speed into the volute pump shell. Liquid in the volute, due to the widening of flow reduction, can and will be part of the kinetic energy into static pressure, finally to high pressure into the discharge pipe, sent to the need to place. Liquid flow to the outer edge by the impeller center, formed the certain vacuum, in the center of the impeller by the pressure on the top of the holding tank liquid level is greater than the pump pressure, at the entrance of the liquid was continuous pressure into the impeller. Visible, as long as constantly rotating impeller, liquid will be overtaken by suction and discharge
