Jinan Saijun CNC Technology Co.,Ltd is one of the top level fd-311c pneumactic polyurethane foam machine manufacturers and suppliers China, welcome to check fd-311c pneumactic polyurethane foam machine price and quotation with us, and wholesale cheap pu spray foam, pu spray equipment, china pu foam machine, good quality polyurethane spray machine, spray polyurethane foam roofing, polyurethane spray machine price, polyurethane foam machine made in China from our factory. FD-311C pneumatic and high-pressure polyurethane spray machine has obtained CE certification, safe and environmental protection. Having the proprietary property rights in design and production, several national patents have been applied and approved. The perfect coaxial structure design of the horizontal booster pump reduces greatly the abrasion of the sealing. There is no pressure difference during operation and the commuting pressure fluctuation value is ideal and stable. The lubricant inside the anti-solidifying lubricating cylinder circulates with high speed so that the leaked material and impurities could be brought away rapidly. The shaft for black material is always kept in the lubricant avoiding the crystallization. The pneumatic commuting control assembly is simple in structure and reliable in operation, and enables the pump body operating normally during the lack of electricity. The design and application of the reset function when shut down realizes the dual protection. The dual filters of the equipment for both high and low pressure and the filter of the nozzle realize the triple filtration protection for the raw material and reduce the blocking. The special armoured temperature sensor inside the heater can collect the temperature signal at any time, hence the overshooting value for heating is well controlled. The flagelliform armoured temperature sensor inside the heating tube makes the collection of the temperature data more sensitive and accurate without signal losing. The heating tubes adopt special technology for winding the heating copper belt. The heating is even and reliable. The tubes are safe and durable with full closed water-proof connection, as well as the heat insulation layer and anti-abrasion layer. The accurate action counter makes it easy to have the knowledge of material consumption when stop working. The compact control panel and the operation hint of key parts make it easy for fast handling and operation. The equipment frame uses the solid rubber wheel dispensing with air filling which is more suitable for the construction site. The equipment is of humanization design with low weight, small volume. It is convenient and flexible and can contain 4 groups of heating tubes (90 meters). It can be easily shifted by one person. Guarantee and after-sale service 1. 18 months guarantee for whole machine except artificial damage. 2. 24 hours technical support by e-mail, skype or telephone. 3.
