1. CWK-11 bellows differential pressure controller is a protection device for ammonia pump or other machinery in refrigeration system. It guarantees the minimum pressure head that the ammonia pump must have in its normal operation. If the ammonia pump head is too low, the flow rate is insufficient, and the liquid shortage operation will damage the ammonia pump and affect the cooling.
2. CWK-11 controls the true head of the ammonia pump, independent of the absolute value of the inlet pressure and outlet pressure. When the pressure difference between the two ends is that the ammonia pump head does not reach the required set value, CWK Type -11 is the automatic delay of the on-delay relay. When the pressure rises during the delay, the switch contacts can jump back, the delay is stopped, and the ammonia pump continues to work normally. For example, until the end of the delay, the pressure still cannot make the switch touch. The head jumps back, that is, the pump is automatically stopped.
3. The CWK-11 type does not have a delay mechanism itself, and an external delay relay is required. The bellows and air box are made of stainless steel, which can be used not only for ammonia pumps but also for other liquid pumps.

Introduction

   

Working principle:

     The CWK-11 differential pressure controller consists of two opposite sensitive components (corrugated pipes) that adjust the faceplate in the housing. When the ammonia pump is just started, the pressure difference has not been established at both ends. In order not to make the differential pressure controller act at this time, the time delay relay must be added. 

     After a certain time delay, the pressure difference is established, and the bellows in the bottom air box is compressed. , generating displacement, and leveraging to make the switch act. During operation, if the pressure head does not reach or equal to the indicated value, the spring force causes the bottom bellows to elongate, the lever moves down, the switch jumps back, and the time delay relay is turned on.
