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:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa
Q:What's the word "pump"? Is that what advocates mean?RT
The words should be decided by the object that everyone supports. The supporters are called "fans"; those who support the singers are called "fans"; the people who support "stars" are called "fans". If the idol supported by everybody is called "shadow" and "view",Star of song? It can not be called "what fans", can only be called "fans"!
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
Q:How about the depreciation of vacuum pumps?
(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
Q:Why is the submersible pump tripped on an electrical switch?
Submersible pump cable or motor insulation is damaged.3) motor water solution
Q:What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
When the valve is closed off opposite is the first current to the rated current, avoid instant electricity loss of other electrical equipment caused by voltage fluctuation. At the same time, some centrifugal pump outlet check valve is not installed, the role of avoiding the pipeline caused by backflow of water pump reversal.This Regulation (or operation regulation) is generally applicable to larger power centrifugal pumps. For small power equipment, it can be used to determine whether the above operation is necessary for actual use
Q:Advantages and disadvantages of centrifugal pumps?
The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!
Q:Why is the sewage pump device coupler?
The automatic coupling device but the installation of GAK type submersible sewage pump, need lifting, people may not need to unscrew the screw water, the water pump can directly improve, after repairing down along the guide rail can realize sealing pump and pipeline, water pump and normal operation. Small sewage pump can be installed freely, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.
