Central Heating Oil Hot Water Boiler Horizontal Gas

Central Heating Oil Hot Water Boiler Horizontal Gas

Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, steam boiler pressure controller and debugging method acting pressure controller is a pressure signal into an electric signal electromechanical conversion device, its function will be the high pressure or low levels of The electrical switching signal to the external circuit for automatic control or chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the oil / gas, and always keep the pressure stable operation. Currently electrical contacts have been rarely used. Above the boiler pressure controller typically uses steam boiler pressure controller are used two to three pressure controller. Wherein a start and stop control furnace, for controlling a large and small fire conversion, there is used an overpressure protection. Two start and stop the boiler pressure controller is generally used to control the temperature controller, pressure controller is arranged to control the two-position and fire the boiler overpressure protection. Three safety accessories on the boiler must be in accordance with the procedures set two, which is intended primarily for safety. First, you can work to prevent another when one of them fails. Second, the purpose of comparison, in particular water level gauge and a pressure controller, to ensure safety, the operator to observe only one of which is the value indicated, but also controls the display shown two values ​​match. 3 generally require a pressure controller, operation is as follows: the first is a power adjusting; e.g. a small fire is set 0.5MPa, 0.4MPa furnace start, the adjustable screw -difference pressure controller (hysteresis) is 1, range (set value) is set to 5. The second pressure is shutdown, diffe set to minimum, range adjusted to 6 (0.6MPa). The third overpressure alarm is set at about 0.7Mpa. Note: the pressure differential must first be transferred back controller adjustment process, and then transferred range. Gas steam boiler pressure controller debugging, generally follow the principle: high pressure, is used as the overpressure protection; high pressure, as boiler start-stop control; low pressure, as a large and a small fire conversion. Specific pressure range may be adjusted according to the nominal pressure boilers and the requirements of use.

Multiple protection devices take you through the oil steam boiler oil steam boiler water level protection, boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. Steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection, having imported burner flame protection means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

With this knowledge points, easily handle common fault boiler pump gas boiler pump is an important equipment, mainly for replenishment aspects boiler. Once the water pump fails, will first trigger replenishment system abnormalities, then water level gauge, pressure gauge, valve instrument will throughout the spate of error, and thus lead to serious boiler accidents. We have compiled the boiler pump five common faults; mastered them, to help you easily cope with pump failure. A lack of flow causes: Effect of multiple pump flow is insufficient suction pipe leakage, valve leakage bottom; inlet plug; insufficient depth of the bottom valve into the water; the water pump speed is too low; sealing ring or excessive wear of the impeller; and other highly absorbent excessive . Solution: Check the suction pipe with the bottom valve, blocking the leakage source; clean mud inlet at the outlet or plug; end of the valve must be greater than the depth of the water inlet pipe 1.5 times the diameter, to increase the depth of the bottom valve into water; check the power supply voltage, increase pump speed, replace the seal ring or impeller; reduce the installation position of the pump, or the replacement of the high lift pump. Second, causes excessive power consumption: pump speed is too high; the pump shaft bending or misalignment of the spindle motor or pump shaft and not parallel; inappropriate selection of the pump head; pump suction sediment or obstructions; motor ball bearing damage. Processing Method: check circuit voltage, reducing the pump speed; correct or adjust the relative position of the pump shaft and the pump motor; with a suitable pump head; or clean sediment blockage; three ball bearings replace the motor, pump noise or rattling Cause: pump installation is not strong or high pump installation; motor ball bearing damage; pump shaft and the motor shaft bending or misalignment, and the like are not parallel. Approach: install stable pumps or pump with reduced height; replace motor ball; correction bent pump shaft or adjust the relative position of the pump and motor. Fourth, the motor shaft, or bearing overheating causes: lack of lubrication or bearing rupture. Approach: filling oil or replacement. V. No water causes: pump and suction tube not filled with water; level below the pump filter tube; suction tube rupture. Processing Method: negative end of valve failure, filled with water; reduce the installation position of the pump, so that water drainage pipe under the action, or the like movable liter water filter and then pumping water; the suction pipe repair or replacement
