XD series vacuum pumps

XD series vacuum pumps are available for low and medium vacuum fields, which are mainly used for pumping air and other dry gases rather than corrosive, toxic, flammable and explosive gases. Furthermore, they cannot pump the gases containing tiny particles or dust and cannot transport other small objects.

XD series vacuum pumps can work for long term in the well-ventilated room with ambient temperature of 5-30 ℃ and with humidity ≤80%.

In addition to the above applications, the XD series vacuum pumps can be available other applications, such as:

1. To increase the amount of the pumping gas and to improve the vacuum degree, please combine with Roots pumps to form a unit for this.

2. If pumping moist air or condensable gas, the condenser can be installed before the vacuum pump and the gas ballast valve is installed on the vacuum pump.

3. If pumping the gases containing dust particles, the dust filters can be installed in front of the vacuum pump.

4. If pumping the corrosive gases, the corrosion-proof gas filter can be installed in front of the vacuum pump.

Q: What are the causes of pump shock?: Troubleshooting cause1. bearing damage, replace new bearings2., coupling pin, bolt damage, rubber column or metal bolt wear, change

Q: What are the characteristics of a pipe shield pump?: According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.

Q: What are the starting and stopping procedures for centrifugal pumps?: Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.

Q: Concrete pump 125 pipe wall thickness: Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q: What does electromechanical vector pump mean?: Scope of application is;Residents living water: such as high-rise buildings, residential areas, villas and so onPublic places such as hospitals, schools, gymnasiums, golf courses, airports, etc

Q: What is a positive displacement pump? He Weizheng displacement?: And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.

Q: I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: Specification for concrete cylinders:Bore * stroke mm 200 * 1650Hopper capacity L 800Feeding height mm 1400Motor model Y2-280M-4Power kw 90Rated voltage V 380Rated speed r/min 1480Soft starter withoutHydraulic system open-loop

Q: What are the conditions required for hydraulic pumps to complete oil absorption and compression?: Volume conditions: oil absorption cavity from small to large, complete oil absorption, oil pressure chamber has become smaller, complete pressure oil.Sealing conditions: the hydraulic pump itself should have good sealing

Q: Do you have a suction pump higher than 9 meters?: Pump rated suction generally 7 meters or so, it is estimated that no one calibration pump suction stroke 9 meters. Calibration suction range of 9 meters is not reliable.

Q: Significance of water pump model ISO50-160: According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
