Product Description:

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:Pump operator's responsibility Sharing the rules, responsibilities, etc..
7., master the knowledge of concrete mix ratio, strictly forbid to add water to the pump at will.8., concrete mixing and workability, gravel diameter is too large, effectively refuse to pump.9. when the delivery pump fails, it can analyze the cause and quickly eliminate the trouble.10. pump complete, you must clean the pump body and pressure pipe residual.11. complete other temporary work assigned by the leader.
Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
(1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
A standard atmospheric pressure can be 10.33 meters to 30 meters of water, suction is atmospheric pressure there are three standard atmospheric pressure so high? This is impossible in general, remove the vaporization removed 0.5 meters critical yo,
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:Working principle and structure of external gear pump
When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.
Q:Pump unloading in hydraulic transmission,
Can be used for short-term shutdown, pump non-stopNo unloading, usually through the overflow valve back to the tank, high pressure, power, at this time insurable pressure, and so on
Q:What kind of motor does the hydraulic pump need?
Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element. Hydraulic pump according to the structure is divided into gear pumps, piston pumps, vane pumps and screw pumps.
Q:What are the application areas of pumps?
Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:
