Engineering construction with rotary vane vacuum pump? - - - - - -

rotary-vane vacuum pump are the most critical problem is usability problems, because of the rotary-vane vacuum pump is used in the liquid, to transport medium are some liquid containing a mixture of solid matter, so very close to the pump and motor, water pump vertically, the weight of the rotating parts and the direction of the impeller. These problems make the rotary-vane vacuum pump in a sealed, motor bearing capacity, bearing arrangement and selection than ordinary sewage pump has a higher request.

refers to the construction project construction, piping and equipment installation project, building decoration and decoration projects such as construction, extension and reconstruction. It's fixed assets formation and other construction projects related to the general production process.

( 1) Construction projects including mines, railways, tunnels, Bridges, DAMS, power stations, docks, airports, stadiums, building ( Factory, for example, theatres, hotels, shops, schools and homes) 。

( 2) Piping and equipment installation engineering including electricity, communication pipeline, oil, gas, water supply, drainage, heating and other pipeline installation of the system and all kinds of machinery and equipment.

( 3) Building decoration engineering, is through the use of building decoration materials to modify the appearance of the building and internal, in order to meet internal and external environment of the building engineering quality requirements.

( 4) Other construction work including the construction unit and the investment decision of the competent department of the activity, as well as land acquisition, engineering survey and design and construction supervision. The work is necessary for engineering construction.

in order to improve the service life of rotary vane vacuum pump, most manufacturers are now trying to protect the pump, when the pump leakage, overload and overtemperature of failure, can automatically alarm and automatically stop the maintenance. However, we think it necessary to provide protection in the rotary vane vacuum pumps system, in order to effectively protect the safe operation of electric pump.

compared with ordinary vacuum pumps, rotary vane vacuum pump has the following advantages:

1. Easy to use, easy to install and maintain;

2。 Rotary-vane vacuum pump are equipped with angry town valve, in order to remove a small amount of water vapor;

3。 The limit of the rotary-vane vacuum pump are high vacuum degree;

4。 Built-in forced oil, lubrication, reliable performance;

5。 With automatic oil return double safety device;

6。 Even if the inlet pressure of 1. 33 x 10 pa, can also be run continuously;

7。 No oil, no oil, no pollution to the work environment.

it is because of the above advantages, rotary vane vacuum pump has been more and more attention by people, using range is becoming more and more widely. From the initial pure water transport to now, it can transport all kinds of domestic sewage, industrial waste water, construction drainage, liquid feed, etc.

The increasing consumption demand in key segments such as pool cover drain pump, winter cover pump and pool cover drain pump have been driving the sales of and its derivatives worldwide.

water pump also offers several other winter cover pump that could potentially be useful for manufacturers.
