Long-term Operation And Exhaust Pressure Of Screw Refrigerator

If the screw chiller is in the process of long-term operation, it will directly cause its equipment to be blocked by scale, which will directly reduce the efficiency of its screw chiller, which will directly lead to an increase in the energy consumption and life of its equipment. shorten.

If the scale in the screw refrigerator cannot be removed in time, the equipment will directly face the danger of maintenance and shutdown. For a long time, the traditional cleaning methods include chemical cleaning, mechanical methods and high-pressure water. many problems.

There are many parts that need to be lubricated during operation of the screw refrigerator, such as the sliding bearings before and after the screw of the equipment, the relative sliding surface of the rotating screw and the shell, the balance piston of the driving screw and the friction surface of the mechanical seal at the shaft end, etc.

During the operation of the screw refrigerator, it is necessary to select the switch to move to the manual position. During the operation, the exhaust shut-off valve of the compressor can be effectively opened, and the spool valve pointer of the equipment is at the "0" position. , that is, the 10% load position.

In the process of pressing the electric heating button of the screw refrigerator, the heating lamp in the equipment will be on, so after the oil temperature rises to 40 degrees, it is necessary to effectively press the heating stop button and the water pump start button to supply water to the oil cooler.

The screw refrigerator is between 5 and 10 seconds, and the pressure difference between the oil pressure and the exhaust pressure can reach 0.4 ~ 0.6Mpa. If you press the main engine start button in the equipment, the compressor will start, and the bypass solenoid valve A will automatically Open, the oil return solenoid valve C is automatically closed.
