Structural Characteristics
Both inlet and outlet of XBD-S type pump are below the pump’s axial central line.They are perpendicular with axial line and horizontally placed in the middle of pump casing.There is no need to remove inlet,discharge pipeline and electric motor(or some other motors).The pump rotates clockwise from the direction of the coupling.The pump which rotates anticlockwise can also be manufactured according to the requirements,but it should be specified when ordering.
XBD-S type pump is mainly made up of pump casing（1）,pump cover（2）,impeller（3）,shaft（4） and double suction seal ring（5）,shaft sleeve（6） and bearing（15）,etc.Except that the material for the bearing is first grade carbon steel,the remained are all made of cast steel(See the structural drawing of pump).
Pump casing and pump cover compose an impeller’s working room.The installation vacuum gauge and pipeline bolt hole on the pressure gauge are designed for the inlet and outlet flange.After the static balance test on the impeller,it is fixed with the shaft sleeve and sleeve nuts on both sides.The axial location can be adjusted through the sleeve nut.The impeller’s axial force makes use of the symmetric layout of its vane to keep in balance.The rest little residual axial force is borne by the bearing at the shaft end.
The pump is supported by two single-row radial ball bearings.The bearing is installed inside the bearing body at both sides of the pump casing,and lubricated with solid lubricant.The double suction seal ring is used to reduce the amount of leakage of water at the pump impeller.
Pump is directly connected with the electric motor through elastic shaft coupling.(If the transmission with rubber belt must be applied,a support shall be mounted in addition.)
The shaft seal adopts soft packing seal and mechanical seal.In order to cool down the lubricant seal chamber and also to prevent air from leaking into the pump,a water seal ring is mounted among the stuffing.While pump is running, slight amount of high pressure water passes through the concave groove on the centrally-split surface of pump cover into the packing chamber,which functions as water seal.
- Q: How to select metering pump head?
- When it comes to metering pump heads, the usual problem is when they measure acid, chlorine, fluoride, and hydrogen peroxide. Due to the difference in concentration and operating temperature, it is difficult to determine the specific pump head material.
- Q: Is the vacuum pump air compressor?
- No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
- Q: There are second cutting, third cutting, why three times?
- 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 reservoir water heater press the booster pump (high marks)?
- 60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.
- Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..
- 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.
- Q: What are the conditions required for hydraulic pumps to complete oil absorption and compression?
- There must be one or more sealing volumes, and the volume of work is variable;
- Q: Is vane pump good or gear pump good?
- The main working parts of vane pump is provided with a plurality of sliding vane rotor, when the rotor rotates, the eccentric configuration of stator cavity contour or rotor, blade sliding slot in leaves due to volume changes, resulting in the suction effect. The similarities are: 1, rotary type positive displacement pump has self-priming ability, but are not allowed to do; 2, with continuous flow pulsation, but also have flow and pressure; 3, the theory of flow is determined by the working parts of the size and speed, has nothing to do with discharge pressure; 4, rated discharge size, pressure and working parts mainly depends on the pump speed is independent of the sealing parts and bearing capacity; differences: 1) gear pump structure is more simple, reliable, low price; vane pump has complicated structure and high manufacturing precision parts, the blade is easy to get stuck, more sensitive to the oil clean degree and viscosity.
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.
- Q: What is the nominal pressure of the hydraulic pump and hydraulic motor?
- Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.
