China [CN] Concrete pump is used for continuous delivering mixed concrete to the construction site, such as building, bridge and tunnel construction, etc. Our pump capacity ranges from 30m3/h to 120m3/h, and the delivery pressure is from 5Mpa to 20Mpa. The concrete pump can be equipped with diesel engine or electric motor to meet different customers’ demand.
Junhua machinery you can trust
Features
1. We adopt famous brands engine for the pump, such as Siemens motor, Volvo diesel engine, Lovol diesel engine or Deutz diesel engine.
2. The main oil pump uses German Hawe, Rexroth or Japanese Kawasaki brand.
3. The hydraulic hose joint is from American Eaton to ensure safety and no leakage for the hydraulic system.
4. S valve is made of high manganese steel, anti-wearing and anti-high pressure; the splined shaft surface is treated by alloy material, which enhances its abrasion performance and fatigue strength.
5. Glasses plate and cutting ring are made of high hard anti-wearing alloy material, which prolongs their service lives.
6. Seals for big oil cylinder is American Parker brand.
7. It adopts progressive dispenser to supply oil for points of lubrication system, and it can supply oil accurately at regular time, saving grease consumption.
8. High pressure on outlet of the pump to make high building and long distance concrete delivery.
9. Main electrical elements are from Schneider and LG company, which is more reliable.
Lithium
Ion (Li-Ion) battery technology is one of the fastest growing trends in the
tool community, and certainly for good reason. Lithium Ion batteries have the best
energy to weight ratio, meaning they pack the most power with the smallest
amount of bulk. They also experience no memory effect or, lazy battery effect.
This occurs when a battery can no longer accept a maximum charge for having
been repeatedly recharged without being fully used (a common symptom of Nickel
Cadmium (NiCad) batteries). Li-Ion batteries, conversely, have absolutely no
memory and can continually accept a maximum charge. Additionally, Lithium Ion
batteries have a very slow rate of charge loss while the battery is disengaged.
What is the difference between Lithium
Batteries and Lithium Ion Batteries?
The difference is in the chemistry; a
Lithium battery is a disposable power source composed of lithium metal
compounds - the key word, here, being disposable; Lithium
batteries can not be recharged. Lithium Ion batteries, on the other hand,
are intercalated, meaning the lithium ion inside the battery moves between two
internal electrodes. This movement, or reversibility of the lithium ion accounts
for the battery's rechargeability.
What are the benefits of Lithium Ion
Technology?
-- Lithium
Ion batteries hold a lot of power and are surprisingly light-weight,
especially with consideration to other rechargeable batteries.
