Embodiment Construction

[0019] As shown in Figure 1, the time-adjustable differential pressure controller is composed of copper sodium 1, high-pressure gas tank 2, differential pressure scale pointer 3, differential pressure scale plate 4, differential pressure spring assembly 5, shell 6, and differential pressure adjusting disc 7. It consists of a low-pressure gas tank 8, a lever pull plate assembly 9, a time adjustment pointer 10, a mask assembly 11, a time control module 12, a micro reset switch 13, an incoming coil 14, and a micro switch 15. Copper sodium is the fixed oil pipe and the adjustable time-delay differential pressure controller. , the differential pressure scale pointer is screwed tightly to the screw in the lever pull plate assembly, the differential pressure scale plate is fixed outside the shell, and the differential pressure adjustment is coiled on the screw in the differential pressure spring assembly to adjust the position of the differential pressure pointer and the size of the d...

Abstract

The invention relates to a time adjustable pressure differential controller in the technical field of a pressure differential controller and an assembly method thereof. The design of the pressure differential controller is characterized in that a copper joint is connected with a high-pressure air tank and a low-pressure air tank of an adjustable delay pressure differential controller, the copper joint is pushed against the high-pressure air tank and the low-pressure air tank to a pressure differential spring component, and the pressure differential spring component drives a lever pulling plate component and a pressure differential dial pointer; a setting dial adjusts the position of a pressure differential pointer and the differential pressure; a microswitch is provided with three stop spool pins, a switch contact is in contact with the lever head of the lever pulling plate component, and when one circuit is cut off, the other circuit is conducted; a time control module is directly arranged on the housing and is used for adjusting the needed protection time by a time adjustment pointer. The invention has the advantages of small volume, little consumptive material, high reaction sensitivity, small repeatable accuracy error, no influence of environmental temperature, adjustable delay time, wide range of time adjustment and feasible assembly method, and is suitable for the application in an oil supply protector of a center air-conditioning unit.

Description

technical field [0001] The invention relates to a time-adjustable time-delay differential pressure controller used in a protection mechanism of a central air-conditioning unit, and belongs to the technical field of differential pressure controllers. Background technique [0002] When the central air-conditioning unit is running, the oil pump supplies oil to the compressor. There is a pressure difference between the front and rear of the oil passing through the compressor. Install a differential pressure protection controller. At present, the differential pressure controllers produced at home and abroad are divided into manual reset differential pressure controllers with delay and automatic reset differential pressure controllers without delay. The old differential pressure controllers are large in size and have many consumables. bar pressure. Among them, the non-delayed automatic reset pressure difference controller is not suitable for the slow establishment of pressure di...
