Introduction
QBK series pump is an air operated double diaphragm pump, which is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side. This pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc.

Features
1. The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self -priming height is 5m and 8m respectively.
2. With sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.
3. Our pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.
4. Pumps provide stall-free, ice-free operation.
5. Bolt joint design provides even sealing pressure for optimal performance.
6. Diaphragm,ball and ball seat adopt imported materials with longer service life.
7. Due to their pneumatic motor, they could be used in potentially explosive areas.
8. Can pump corrosive , volatile, flammable, poisonous fluids with particles and high viscosity.

8. After-sales Service: We will full report you the production progress and plan. Meanwhile, we will follow up the pump working conditions per three months when the pumps put into use, and can send the spare parts to you within one week if u need.
Our Company
Lithium battery is a kind of lithium metal or lithium alloy as the anode material, the use of non-aqueous electrolyte solution of the primary battery, and rechargeable battery Lithium ion battery and lithium ion polymer battery is not the same. Due to the very active chemical properties of lithium metal, the processing, preservation and use of lithium metal require very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronic technology at the end of the 20th century, the miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium battery then entered the stage of large-scale application.
lithium metal battery
Lithium metal battery is a kind of battery which is made of lithium metal or lithium alloy as anode material and uses non-aqueous electrolyte solution. The earliest lithium batteries used the following reaction: Li+MnO2=LiMnO2, which is a REDOX reaction, discharge.
lithium ion battery
Positive electrode materials: There are many optional positive electrode materials. At present, the mainstream products mostly use lithium iron phosphate. Different cathode materials as follows:
|
LiCoO2 |
3.7 V |
140 mAh/g |
|
Li2Mn2O4 |
4.0 V |
100 mAh/g |
|
LiFePO4 |
3.3 V |
100 mAh/g |
|
Li2FePO4F |
3.6 V |
115 mAh/g |
Lithium batteries generally fall into two main categories:
Lithium metal battery: Lithium metal battery is generally the use of manganese dioxide as the positive material, lithium metal or its alloy metal as the negative material, the use of non-aqueous electrolyte solution of the battery.
Lithium ion battery: Lithium ion battery is generally used lithium alloy metal oxide as the positive material, graphite as the negative material, the use of non-aqueous electrolyte battery.
