Arc gear pump common fault and maintenance methods

First, the arc gear pump common faults and countermeasures: 1, the phenomenon of failure: pump flow arc gear pump failure reasons: 1) suction or discharge valve is closed; 2) inlet pressure is low; 3) outlet pipe plugging; 4 ). Stuffing box leaks; 5). Speed ​​is too low. Countermeasures: 1) Confirm whether the valve is closed; 2) Check whether the valve is open; 3) Check if the discharge volume is normal; 4) Tighten; . 2, the phenomenon of failure: the pump can not discharge the cause of the malfunction: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet or the pressure is too low; d, viscosity is too high, the pump can not bite material. Countermeasures: a, confirm the direction of rotation; b, confirm the valve is closed; c, check the valve and pressure gauge; d, check the liquid viscosity, low speed operation according to the speed ratio of the flow rate appears, if the flow, the inflow is insufficient. Second, arc gear pump operation and maintenance methods are: 1, check all the flanges before the start of the joint tightness. 2, disc drive coupling, no friction and collision sound. 3, the first start should be injected into the pump liquid. 4, before starting the full suction and discharge Valves in the pipeline, closed valve is strictly prohibited to start. 5, verify the direction of motor rotation, start the motor. Arc gear pump in the use of a period of time after regular maintenance and repair to ensure that arc gear pump better operation

Angle Valves

Globe valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.

Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
