Comparison between hydraulic filter press and mechanical filter press

Nowadays, the filter press market is dominated by hydraulic filter presses and mechanical filter presses. What is the relationship between them? What is the difference? Let's talk about it today.

Hydraulic filter presses and mechanical filter presses are classified according to the pressure source of the filter press. The difference between them is that the pressure is supplied in different ways. The pressure of the mechanical filter press on the filter plate is the rotation of the motor from the filter press device, which drives the gear and rotates the corresponding structure of the gear to advance or retreat before the screw connected to the filter plate, thus realizing the filter press Two processes of applying pressure to the filter chamber, squeezing and pulling back the filter plate, and relaxing. The hydraulic filter press realizes the power of the two processes on the hydraulic system. The hydraulic system of the hydraulic filter press consists of a hydraulic station, a hydraulic chamber and a controller. Through the hydraulic station, the hydraulic oil passes through the hydraulic station. The twitching conveys the hydraulic oil in the hydraulic station into the conduit, which then passes the hydraulic oil through the controller and into the forward or reverse chamber of the hydraulic chamber, pushing the piston of the hydraulic chamber back and forth, and driving the power through the lead screw. Transfer to the push filter plate of the filter press chamber.

The hydraulic filter press is developed on the basis of the mechanical filter press. It is an important representative of the short development of the chamber filter press equipment. Therefore, the hydraulic filter press integrates many mechanical filter presses. Optimization, such as the pressure provided by them has increased significantly; full mechanization, completely changed the manual labor of the manual filter press; they have obvious acid, alkali and wear resistance Improve, adapt to a more difficult working environment; greatly improve the use of filter press industry.

However, the hydraulic filter press has made great progress on the basis of the mechanical filter press, and the largest is the automatic pressure holding of the filter press. When the pressure in the filter chamber of the filter press is less than the designed pressure, the hydraulic filter press can automatically restart the hydraulic system to continue to supply pressure to the hydraulic filter press. When the upper limit of the pressure is reached, the hydraulic system will be automatically powered off and the hydraulic system will be stopped. The hydraulic filter press provides the necessary conditions for the automatic filter press, which is the beginning of automation, informationization and intelligence of the filter press.
