As a common solid-liquid separation equipment, the plate and frame Filter Press is widely used in the fields of chemical industry, food, pharmaceutical, environmental protection, etc. However, there are many brands of Plate and frame filter presses on the market, and the quality varies, making it difficult for many buyers to distinguish. So, how to identify the quality of the plate and frame filter press? Here are some reference indicators for you.

Observe the appearance and surface treatment of the equipment. A good plate and frame filter press should have a complete appearance, the welding seam should be flat and smooth, and there should be no obvious flaws and scratches. At this time, you can touch the welding part and the surface slightly. If it feels smooth, it means that the surface treatment of the equipment is relatively delicate, indicating that the manufacturing process of the equipment is relatively good.

Pay attention to the material and size of the filter plate. The filter plate is the core component of the plate and frame filter press, and its quality directly affects the performance of the equipment. A good filter plate should be made of high temperature resistant, corrosion resistant, and wear resistant materials, such as stainless steel. The size of the filter plate also needs to meet actual needs. Too large or too small will affect the filtering effect.

Check the sealing performance of the filter press. The plate and frame filter press needs to form a closed filter chamber when working, otherwise it will cause leakage, thus affecting the filtering effect of the equipment. You can inject some liquid into the filter chamber after turning off the equipment. After observing for a period of time, if there is no obvious liquid leakage, it means that the equipment has good sealing performance.

Also check the filtering effect of the equipment. A good plate and frame filter press should have a high filtering and purification efficiency and a low residual moisture rate. You can inject some liquid samples into the equipment for filtration, observe the particle size and moisture rate of the remaining substances after filtration, and evaluate the filtering effect of the equipment accordingly.

Review the convenience of equipment operation. A good plate and frame filter press should be simple and easy to operate, and each part of the equipment should be easy to disassemble and clean for daily maintenance and maintenance. The degree of automation of the equipment also has an important impact on the convenience of operation. The automatic control system can improve the stability and work efficiency of the equipment.

Pay attention to the credibility and after-sales service of the equipment supplier. Choose a supplier with a high reputation, and the quality of the equipment produced by it is usually more reliable. At the same time, the after-sales service of the supplier is also very important. Providing technical support and equipment maintenance services in a timely manner can effectively ensure the normal operation of the equipment.

To identify the quality of a plate and frame filter press, it is necessary to examine factors such as appearance treatment, filter plate material and size, sealing performance, filtration effect, and ease of operation, and pay attention to choosing a supplier with a high reputation. When purchasing a plate and frame filter press, consumers can conduct targeted observations and inspections based on the above-mentioned indicators to ensure that they purchase reliable quality equipment.
