The basic performance and uses of high-pressure piston diaphragm pump are as follows: Performance: First, by the eccentric shaft connected to the pump shaft, alternately pushing the rear three plunger, and then push the front three diaphragm to form a high-pressure work. The maximum pressure up to 70kg, special custom models up to 170kg. Second, the pressure and flow adjustment, is by connecting the motor inverter, by adjusting the motor speed to achieve. Third, the mechanical part of the diaphragm is closed, immersed in the lubricant (similar to the car engine). Only the diaphragm and the flow path are in contact with the liquid material. The material and the mechanical part are completely out of contact, so liquids containing solid particles can be removed. Fourth, the fragile parts only the diaphragm and the inlet and outlet of the closed valve, the replacement is very convenient, low cost. Uses: First, the pump is the most prominent feature is under high pressure, the transfer of liquid containing solid particles, with a solid content of up to 50%, suitable for pressure spray drying equipment. Pressure spray drying simply put, is the slurry drying process for the uniform particles. High-pressure pump material hit the top of the spray tower, spray out from the nozzle, drop the process of being hot air tower drying, falling in the bottom of the tower to form particles. Generally require the pressure of 30 ~ 40kg. After the electric drying products need to add grinding, the uneven particles, there are often large particles and dust. Dyes which are now exported abroad are required to be granulated products produced by spray drying due to environmental reasons. Second, deep-controlled drilling, large machining centers, because of its cutting fluid containing impurities such as metal shavings, this pump can be used to spray cooling fluid. Third, desalination of high pressure reverse osmosis filtration device for the liquid.
