Diesel engine pumps are often used for emergency water supply in large-scale projects such as high-rise buildings, water supply companies, steel plants, wineries, chemical plants, hotels, hospitals, and so on. It is suitable for unattended emergency water supply system. The product has the characteristics of good technology, high degree of automation, superior performance, complete function, reasonable structure, simple installation, high cost performance and so on.
The diesel engine water pump is more convenient and flexible than the stationary diesel engine pump, and it is easy to move to suit different places. According to the needs of different working conditions, domestic or imported diesel engines can be selected, and self-priming (or vacuum water diversion device) centrifugal pumps are supported.
During the non-use period, the pump should be lifted away from the water source in a timely manner, and the accumulated water in the pump should be drained, especially in the cold winter. Then put it in a dry place, and qualified users can also apply butter to key parts and add lubricating oil in the bearing to prevent parts from rusting. In addition, the non-use period of the diesel water pump is not as long as possible. If it is not used for a long time, it will not only easily rust the parts, but also reduce the service life.
If there is water leakage in the use of diesel engine water pump, how should we repair:
1. After the diesel engine water pump shaft and shaft sleeve are worn, the shaft can be restored to the standard size by electroplating or vibratory surfacing. At the same time, a new standard sleeve shaft can be replaced, or a new shaft sleeve can be replaced and the inner hole is reamed according to the size of the shaft Make the worn shaft and the new sleeve reach the standard fit clearance.
2. The pump shaft is supported by two rolling bearings. When the water pump shaft and the rolling bearing are loosened, the inner ring of the electroplated bearing can also be used to restore the coordination.
3. If the cooperation between the pump body seat hole and the bushing or rolling bearing is loose, the outer ring of the plating bearing can be restored to its standard fit according to the wear parts of different models, or the housing hole seat can be boring and reaming to eliminate wear Trace, and according to the hole diameter after reaming to prepare a bush with an enlarged outer diameter to restore its standard fit. If the hole seat of the pump body is seriously worn, it can also be repaired according to the situation. For cracks on the shell, a crack stop hole with a diameter of 2.5 mm can be drilled 5 mm away from the two ends of the extension line, and the V groove is opened along the crack, and the cast iron electrode is welded by oxygen-acetylene cold welding or manual arc cold welding. .
4. The aging or damage of the water blocking ring should be replaced. The water seal nut should be tightened for the water leakage of the submersible sewage pump. If the water seal nut is tightened, the water still leaks. This is the wear of the seal ring and the sealing seat surface, the rupture of the rubber water seal bowl and the failure of the water seal spring. If the sealing ring and the sealing bowl are damaged, the water seal assembly should be replaced; the end surface of the sealing ring is worn and can be ground;
Expanded Steel Diamond Mesh is another kind of metal screen
industry, which is also one of the main varieties of metal plate mesh. Also
known as expanded metal mesh, expanded diamond mesh, expanded metal lath, heavy
steel plate net, foot net, punching plate, etc. After the steel mesh punching
machine processing, the metal plate becomes a mesh with mesh of diamond.
Size: Opening size (mm): 2.5-50mm or according to customers`
requirements
Thickness (mm): 0.5-10mm or according to
customers` requirements
Material: High quality low carbon steel plate,
aluminum plate, SS plate, titanium plate, aluminum foil plate, nickel plate,
galvanized plate etc.
Surface

powder coated
Use: Expanded sheet used for filter,
medicine, papermaking, filtering, breeding, cell network, packaging net,
mechanical facilities protection, handicraft manufacturing, high-end speaker
net enclosures, decoration, child seat, basket, basket and road protection,
foot tanker net, heavy machinery and boilers, oil mine, locomotive, million
tons of ships such as working platforms, escalators, walkways. It can also be
used for reinforcing steel bars in construction industry, highway and bridge.

Expanded Metal Process
If you are curious about
how the process of forming expanded metal mesh, XinZheng is happy to provide
you with a step-by-step guide to manufacturing these products on our
state-of-the-art equipment.
1. Sheet
or plate is advanced beyond the face of the bottom die in an amount equal to
the strand width before flattening. The sheets are then fed into an expanding
machine.
2. The
top die then descends and simultaneously slits and cold forms an entire row of
half diamonds.
3. The
top die then ascends and moves one half of a diamond to the right as the base
sheet or plate moves forward one strand width.
4. The
top die descends, slits and forms another full row of half-diamonds completing
a row of full diamonds in two strokes.
5. The
die then ascends and returns to its initial position.
This process then
continually repeats until the full sheet of expanded metal is completed. This
mesh is then either cut into sheets or rolled into coils for either shipping or
additional processing.
