SCR water pump pressure regulation control device

Abstract

The silicon controlled silicon water pump pressure adjustment control device includes the upper cover, the adjustment fixed plate, the circuit board cover and the housing, the upper and lower adjustment switches are placed in the adjustment fixed plate, and the silicon controlled silicon water pump pressure adjustment controller is arranged inside the circuit board cover. The cover, the adjustment fixed plate, and the outer cover of the circuit board are arranged in the casing. A round hole is opened in the upper cover, and the first and second cylindrical straight holes are respectively opened in front of the upper and lower adjustment switches, and the sides of the upper and lower adjustment switches are clamped. Mechanism, adjust the inner groove of the fixed plate, the tooth groove on the side of the inner wall, the pressure adjustment controller of the thyristor water pump includes the water pressure gauge, the control circuit board, the thyristor control switch, the upper and lower dead center magnetic switches, the input plug and The output socket, the pointer of the water pressure gauge is equipped with a magnet to cooperate with the magnetic switches of the upper and lower dead points. The thyristor control switch is located at the bottom of the control circuit board, and is fixed with the water pressure sensing device on the water pressure gauge by screws. The control circuit board Upper system control circuit.

Description

technical field [0001] The invention belongs to the field of pressure control devices, in particular to a pressure regulation control device for a silicon controlled silicon water pump. Background technique [0002] The water pump pressure adjustment control device mainly refers to the control device applied to the water pump. When the water pressure is lower than a certain value, the controller in the control device is turned on, and the water pump starts to work. When the water pressure is higher than a certain value, the controller cuts off the power supply. The water pump just stops working. [0003] Existing water pump pressure controllers are mainly divided into two types: mechanical control and electronic control. The existing mechanical water pump pressure controller is controlled by spring pressure. The contact points are easy to burn out, and the service life is short. At the same time, the controller uses a rubber gasket, which is easy to be damaged. The existin...

Problems solved by technology

[0003] Existing water pump pressure controllers are mainly divided into two types: mechanical control and electronic control. The existing mechanical water pump pressure controller is controlled by spring pressure. The contact point is easy to burn out, and the service life is short. At the same time, the controller uses a rubber gasket, and the gasket is easy to be damaged.

The existing electronic water pump pressure controller uses an electronic circuit to control a single-contact relay in its actual structure. The disadvantages are: if the circuit cuts off the neutral line, the live line is always open, which may easily cause electrification of the water pump and accidents, and the action of the relay contact is slow. It is also easy to burn out. If electronic control is really used, the problem of heat dissipation is difficult to solve
