Product Description:

MD type wearable centrifugal mine waterpump is used to transport the clear water and the neutral liquid of pit water with solid grain 1.5%. Granularity < 0.5mm.The temperature of the liquid is not over 80℃. The pumps are suitable for water supply and drainage in mines, factories and cities.

Range of performance
(Q) 25-750m³/h
(H) 60-1798 m

Model MD pump consists of four parts, stator, rotor, bearing and shaft seal:
1.Stator consists of inlet, middle and outlet sections and the guide vane etc., with the take-up bolt tightly clamping all sections to form a working room. The inlet of it stands horizontally while the outlet vertically upward.
2.Rotor consists of the shaft, impeller, balancing disk and muff etc., the shaft passes the power to the impeller to have it work; the balancing disk balances the axial force; and replaceable muff is mounted on both sides of the shaft to protect it.
3.There are rolling and sliding bearings:
The rolling bearing consists of bearing seat, bearing and bearing gland and uses grease for lubrication.The sliding bearing consists of bearing body and cover,liner, dust-proof disk, oil leveller, oil throwing ring etc., and uses thinned oil for lubrication.
4. The shaft is sealed with stuffing and the shaft seal consists of the sealing contents, stuffing, baffle. The liquid in the sealing work-room functions water-sealing, watercooling and water lubricating and the water for watersealing comes from the pressure water inside of the pump.
In addition, the pump is directly actuated by the prime mover through the elastic clutch and, viewing from the prime mover, moves CW.

Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
In order to make the pump full of liquid, usually in the valve installed at the bottom of the filter screen along the suction pipe, the valve until the end against the valve, strainer prevents the solid material into the normal operation of the pump impeller damage or hinder the pump.
Q:What does the impeller on the centrifugal pump mean by the first cutting?
So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Normal words are needed, but when you check and check, has anyone checked?
Q:What does "dual purpose" of water pump mean? Please expert advice
In order to ensure safe and continuous operation, three pumps usually need two units and run one standby.Precautions for using pumps1, if there is any small water pump failure, remember not to work. If the pump shaft packing end wear should be added in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller.
Q:What are the constant pressure pumps?
Chlorine booster pumpThe pressure range of chlorine booster pump is large, and different pump can be used to obtain different pressure area. The input air pressure is adjusted and the output pressure is adjusted accordingly. High pressure can be reached, gas 90Mpa. Wide range of flow, for all types of pumps only 0.1Kg pressure can work smoothly, at this time to obtain the minimum flow, adjust the intake volume can be obtained after a different flow. Easy to control, from simple manual control to fully automatic control, can meet the requirements. Automatic restart, regardless of what causes the pressure drop in the pressure loop, will automatically restart to supplement leakage pressure and maintain constant loop pressure. Safe operation, gas driven, no arc and spark can be used in dangerous situations.
Q:The function of centrifugal pump
6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.
Q:What are the main performance parameters of the pump?
RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power
Q:How to adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Q:How long does the fine stone pump need maintenance? What should I pay attention to?
- check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re
Q:How to select metering pump head?
The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.
