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's the difference between a centrifugal pump and a centrifugal pump? What are they used for?: Centrifugal pumps are used to transport liquids (or mixtures, waste water, waste materials) from one location to another.

Q:What should be used to pay attention to the use of mechanical pumps?: Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test

Q:What is the pump delivery? What's the difference between years and years?: 1) integer integer: ~ batch. Sell ~.2) buy in bulk: ~ goods. Sell now.The exchange is, according to the duration of the contract delivery insurance premium, payment is generally in common, 5 years of insurance you every year that time, continuous call five years; general single sex 5 years or even 10 years of premium.Furthermore, the insurance premium is good or good pay period, if a single rate from the point of view, to make cheaper than single period, but considering the one-time payment of the interest cost of funds and the opportunity cost, there is no difference. While the single cross ratio advantage is mainly reflected in its flexibility. First of all, additional premium may be added to the premium. At present, additional risks can only be covered if the main risks and principal risks are covered during the payment period. The single way to buy insurance, even in the primary insurance protection period will no longer be able to purchase additional insurance new; secondly, to pay the premium can enjoy a premium waiver. If the insured in full payment period has not yet had the danger, not pay part of the premium would be exempt from the Qing dynasty. For child insurance, the premium waiver is more advantageous. If parents unfortunate accidents or illness, resulting in death or one or two, three disabled or suffering from severe illness, the insurance company will be exempted after the premium, the insurance contract shall continue to be valid; finally, to pay the premium or additional premium amount can be changed. The policy holder may adjust his insurance plan according to the change in his economic strength. In contrast, single premium has the advantage of a one-time payment more convenient.

Q:You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?: For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.
