high pressure airless paint spraying machine

Purchasing guide:
Paint spraying machine falls into two categories as per manufacturing principle and functionality:
1. plunger & diaphragm combined type:
Driven power: (1) electricity  (2) oil burning engine
2. pure plunger type:
Driven power: (1) electricity  (2) pneumatic  (3) oil burning engine
Paint spraying machine performance comparison:
plunger type paint spraying machine：it is suitable to spray water based coatings, comparatively durable, not suitable for big area and long time spraying work.  Air can not be sucked in during working becomes the main shortcoming, otherwise it is easy to damage the seal ring caused by overheating, maintenance cost comparatively high, especially most of them are equipped with brush DA motor which is short life, and switch type voltage stabilizer which not belong to pressure inducted automated device, working pressure is not stable to cause uneven spray. Maintenance cost is higher.    
Plunger & diaphragm combined paint spraying machine：it is suitable to spray oil based and water based coatings, outstanding functionality, and suitable for big area spray, less quick-wear parts and low usage cost, maintenance simple, especially motor maintenance simple, brushless AC motor long life. Automatic high pressure overflow device by use of mechanic type pressure design makes pressure extremely stable. It is know as the king of cost performance ratio. As though manufacturing cost higher, using cost is low, self-weight big, sucking special viscosity coatings capability is not as good as plunger type spray machine, however some models have been renovated, for example JDL6.
