Product Description:

1.   General Instruction

      Type DG pumps are single suction, segmental and multistage

centrifugal pump, which is suitable for pumping the cleaning water

and other liquids with similar characteristic of physics or chemistry

 to water.

      When the head of pump ranges from 100 to 1100 meters, the

capacity ranges from 10 to 100m³/h, the maximum temperature of

liquid pumped is 130. This is series pump is suitable for boiler

feed water, water supplying for factories and cities.

2.    The meaning of pump as following:


       50— inlet diameter(mm)

       DG — multistage and segmental boiler feed water pump

       50 — single stage head(m)

       5 — quantity of impeller

3.    This series of pumps have many advanced features such as

high efficiency, energy-saving. The shaft seal is soft packing gland.

The materials of major parts as follows: suction casing, interstage,

discharge casing, diffuser, impeller——plain cast iron (low pressure

end) and nodular cast iron (high pressure end), shaft——carbon steel.

Q:What's the difference between energy-saving equipment and energy-saving equipment?
Energy saving equipment can include power saving equipment, gas energy conservation, thermal energy saving, etc., and power saving equipment just means saving electricity.
Q:How can I print the label on the energy saving lamp? What equipment should I use?
Pad printing machine, pad printing machine mainly by the printing plate device (including ink supply device), scraping knife, pad printing head (usually silica gel material) and printing desk and so on, belong to one of the special printing methods. It can print characters, graphics and images on the surface of irregular objects.
Q:What kind of equipment will be needed to build a municipal energy monitoring and supervision center?
1) temperature and pressure measuring instrument 1) digital thermometer 2 -30~1400 C 2) dual channel digital thermometer -50~1000 C 2 single channel 3) temperature recorder 1 print 4) infrared thermometer 2 -30~1200 C 5) infrared thermometer 1 600~3000 C 6) temperatureinspectinginstrument 220 channel
Q:What are the kitchen equipment manufacturers? Which kitchen project is more professional?
The central kitchen construction needs five supporting systems, including design and construction system, facilities supporting system, equipment supporting system, management system and supply chain system
Q:A paper on energy saving of building equipment
We must first understand the building energy consumption of building energy consumption two big black hole, black hole; air conditioning and lighting, air conditioning energy must solve the indoor air quality (equipment, you can search in a breeze of 2007 they began to solve equipment, energy saving effect is very ideal.) Lighting to solve the traditional way of lighting, conservative can achieve 50% energy saving effect.
Q:How to evaluate the energy saving of air compressor energy saving equipment?
The most simple, the most intuitive, with a meter, we will add a meter run after 1 weeks of record in the installed electricity installed before running after a week of record, if not up to an average of 29.5, we not only pay you more for electricity will take the machine away, returned to you to buy the equipment about money
Q:What equipment do you need for energy-saving lamp assembly?
Professional equipment brand better are reached, the distance of two volts, want to use so much because the local instrument components in the circuit board assembly is used to match the whole lamp, when assembling the circuit board and the lamp is to match each other in order to use, otherwise it is likely the lamp assembly quality will be very poor, return the rate will be very high.
Q:Investment in energy efficient equipment in GB19762-2005 is offset by corporate income tax
Our problem is combustible gas detection equipment, although we also buy combustible gas detection equipment, but it is to follow the explosion-proof national standard, the equipment production instructions are also marked. However, the equipment conforms to the national standard GB15322 for the detection of flammable gases. The parameters can meet the requirements of GB15322 for combustible gas detection. So, we will use to illustrate the way to indicate, although the purchase of equipment is to follow the explosion-proof GB, but also can meet the list of combustible gas detection GB, so we take the preferential deduction declaration.
Q:What instruments and equipment are needed for building energy efficiency testing?
Equipment needed: building energy saving test indoor environment: temperature and humidity meter, anemometer, air cover system performance: ultrasonic flow meter, power meter, performance envelope: pitot tube heat transfer coefficient measured by conductivity meter.
Q:The principle of infrared switch
Infrared: in the spectrum, the wavelength from 0.76 to 400 microns is called infrared ray, and infrared ray is invisible light. All materials above the absolute zero (-273.15 DEG C) can produce infrared rays. Modern physics is called thermal radiation. Medical infrared can be divided into two kinds: near infrared ray and far infrared ray.
