Previous Preparation Of Plate Heat Exchanger Use

  Plate heat exchangers are ideal for heat exchange between liquid-liquid and liquid-vapor. Preparation before use of the plate heat exchanger is as Preparation of plate heat exchanger before usefollows

(1) The plate heat exchanger is used to loosen each bolt before use in the food and pharmaceutical industries. Each plate is cleaned with a brown brush and assembled in accordance with the process.82-90 hot water is sterilized for 10-20 minutes, and the material pump is started immediately, so that the cooling material can completely eject the remaining water in the plate until it is completely material.

(2) Before the use, the hydraulic pressure test is carried out according to the operating pressure of 1.25 times, and the pressure is kept for 30 minutes without leakage.

(3) Before using the plate heat exchanger, clean the cycle with clean tap water for about 20 minutes.

(4) In the pipeline system, the venting valve should be installed to discharge the air in the equipment to prevent air from staying in the equipment, reducing the heat transfer effect.

(5) The installation of the inlet and outlet of the hot and cold medium shall be connected in strict accordance with the specified direction.

(6) Before using the plate heat exchanger, check whether the clamping bolts are loose. According to the instructions, the size should be tight to the size A to ensure that all the bolts are uniform.
