高压无气喷涂效率高，表面细腻平整，附着力强，涂料损耗少而得到建筑机械船舶家具等行业的广泛使用。 高压无气喷涂机分为气动式无气喷涂机，电动式无气喷涂机（柱塞泵）和电动无气喷涂机（隔膜泵），由于气动式无气喷涂机需要带压缩空气源而限制了气动喷涂机的使用。 现仅将电动柱塞无气喷涂机与电动隔膜无气喷涂机作比较，柱塞泵是将直流电动机带动柱塞复运动将涂料吸入，加压后排出，由于其柱塞裸露，且柱塞在涂料中工作，在涂料研磨作用下柱塞磨损非常快，一旦配备口径较大的喷嘴，其柱塞往复频率提高，加剧柱塞的磨损，机器寿命短。而更换柱塞价格非常昂贵，如果电压不正常也将直接导致工作直流电的不正常。另外，由于大幅来回往复运动，柱塞泵的工作脉动很大，使得喷涂不稳定，涂料喷上的墙面平整度就不够好。但柱塞泵初始吸料较快是其长处。 隔膜式无气喷涂机（隔膜泵），其设计是在柱塞泵基础上得到了更大的改进，原理为用电动机带动活塞往复工作（注意，活塞并不直接接触涂料），再推动隔膜运动，将涂料吸收加压后推出，通过喷嘴喷向涂装物体，由于其活塞在防磨损的油中工作，工作环境大大优化，寿命大大提高，经过掺透硬化处理的活塞更是不易损坏，加上高分子材料制成的高抗绞隔膜更使隔膜泵寿命进一步提高。运行可靠是隔膜泵的又一长处，故障率极底，对电压要求底，对环境要求底，维修容易，维修费用仅为柱塞泵的五分之一左右。 隔膜泵xxx优，其优异的性能价格比将推动隔膜泵的推广。

High-pressure airless spray, high efficiency, smooth surface, fine, strong adhesion, coating loss to be few and construction machinery industries such as shipping furniture, widely used. Airless spraying machine is divided into pneumatic airless spray machine, electric airless spray machine (piston pump) and electric airless spray machine (diaphragm), because of pneumatic airless spray machine with a compressed air source to limit the need of pneumatic spraying machine use. Now only the electric piston airless spray machine and electric diaphragm airless spraying machine comparison is DC motor driven piston pump plunger movement will re-paint inhalation, after the discharge pressure, because of its exposed plunger and plunger In the paint work, paint abrasive wear very quickly under the action of the plunger, once equipped with a larger diameter nozzle, the plunger reciprocating frequency increased, exacerbating the plunger wear, the machine short life. The replacement of the plunger is very expensive, if the voltage is not normally the work of DC will also be a direct result of the abnormal. In addition, due to the significant back and forth reciprocating motion, piston pump pulse of the work of great instability makes the spray coating sprayed on the wall roughness on the not good enough. However, the initial suction piston pump is the strength of fast. Diaphragm airless spray machine (diaphragm), which is designed on the basis of the plunger has been further improved, the principle for the use of motor driven reciprocating piston work (note that the Pistons do not directly contact with paint), and then push diaphragm movement , will launch the paint to absorb pressure through the nozzle, wherein coating objects, because of its anti-wear oil piston in the working environment, greatly optimized, life expectancy has greatly improved through the piston-doped transparent hardened even more difficult to damage, plus on the polymer membrane made of high resistance to twisting is more so that further increases in life diaphragm pump. Reliable is the diaphragm pump is another advantage, the failure rate for the end of the end of the voltage requirements on the environmental requirements at the end is easier to maintain, maintenance costs, only about one-fifth of plunger pump. Diaphragm pump price excellent, its excellent performance and low cost will drive the diaphragm pump promotion.
