Figure 4Q≥1000L/min with temperature regulator device system diagram Oil drain outlet2Q≥1000L/min device to use steam heating: a) When the self-operated temperature control valve is used to open and close the steam inlet, the system is shown in Figure 3, the middle contact of the three-point temperature relay is not closed, and the oil pump cannot start:
b) The device using the solenoid valve to open and close the steam inlet is shown in Figure 4. When the low point of the temperature relay is disconnected or closed, the electromagnetic inlet of the steam is connected, the valve opens to the bottom, and the oil heat pump cannot start: center) When the middle contact is closed, the oil pump can start:) When the high temperature contact is closed, the solenoid valve is automatically cut off, the steam inlet is closed, and the heating is stopped: e) The high, medium and low temperature values are set by the user. 5.4 Device outlet pressure and temperature control
5.4.1 Outlet pressure control
) A pressure relay with three contacts is installed at the outlet of the device to control the outlet pressure. The specific value of the pressure is set on site according to the actual situation and needs:
b) When the outlet oil pressure reaches the high value, the green light will turn on and the interlock standby will stop: e) When the outlet oil pressure reaches the middle value, the yellow light will turn on, the standby pump will be automatically started, and the main engine will be allowed to start working; d) When the outlet oil pressure drops to the low value, the red light will turn on, the interlock will stop and stop. 5.4.2 Outlet temperature control
a) A three-contact temperature relay is installed at the outlet of the hood to control the outlet oil temperature, b) When the oil temperature is at a low value, the main engine is not allowed to start; ) When the oil temperature is lower than the low value + the relay midpoint sends a signal + allows the earthwork to start working: d) When the oil temperature reaches a high value, the high-temperature contact of the relay is closed, and the alarm is switched to manual temperature adjustment to maintain the system working properly. e) The low and high values of the outlet oil temperature are set by the user according to the working conditions. 54. Control requirements for pressure tanks
) Before the pump is started, the pneumatic solenoid gate valve is in the closed state; b) After the oil tank is started, when the system reaches the positive pressure value, the system pressure relay is closed, the pneumatic valve automatically opens, and the pressure tank is put into system operation
\) When the oil level in the tank is lower than the lower limit, the liquid level switch sends a signal and the pneumatic valve automatically closes; d) When the oil level in the tank reaches the highest value, the liquid level switch sends an alarm signal. It is necessary to fill the tank: c) When the system stops working, close the pneumatic solenoid gate valve at the tank outlet to cut off the passage between the tank and the system. 5.5Q A water accumulation alarm control device should be installed in the oil tank of the 1000L/min device (the control device is not shown in the system diagram). 5.6 Electrical control of the device
5.6.1 There are two types of manual switching and automatic switching. 5.6.2 The electric control system adopts two forms: PI.C. programmable control or relay contactor control: 5. 6.3 The circuit diagram of the device control system is shown in Figure 5. 5.6.4 The electric control box of the device:
a) The electric control box of the device of XYHZ6.3-XYHZ200 is shown in Figure 6 b) The electric control box of the device of XYIIZ250~XYIIZ800 is shown in Figure 7. 6 Type, size and marking of the device
