YCB arc high viscosity heat pump is mainly used for conveying various machinery and equipment lubrication systems transport oil, solid particles, non-corrosive, a wider range of lubricating viscosity liquids. Pump flow up to 300 m 3 / h, pressure up to 3 × 107 Pa. It is usually used as a pump and transport all kinds of oil. Gear pump structure is simple and compact, easy to manufacture, easy maintenance, self-absorption capacity, but the flow, pressure pulsation is large and noisy. Gear pumps must be equipped with a safety valve to prevent the discharge pipe for some reason, such as clogging the pump outlet pressure exceeds the allowable value of damage to the pump or the prime mover. Reasons for insufficient pump flow fault:: YCB arc heat pump high viscosity breakdown and repair methods: (1) failure phenomenon a, suction or discharge valve closed; b, low inlet pressure; c, export pipeline blockage; d, stuffing box leakage; e, the speed is too low countermeasures: a, confirm the valve is closed; b, check valves are open; c, to confirm whether the normal excretion; d, fastening; a lot of leaked leak affecting production, should be stopped, demolition inspection; e, Check shaft actual speed; (2) Symptom: Cause pump can not discharge faults: a, rotating in opposite directions; b, suction or discharge valve is closed; c, no material inlet or pressure is too low; d, viscosity is too high, the pump Unable to bite material countermeasures: a, confirm the direction of rotation; b, confirm the valve is closed; d, check fluid viscosity at low speed to whether the proportion of traffic according to the speed, if the traffic is flowing into; c, check valves and pressure gauges insufficient, YCB arc high viscosity heat pump operation and maintenance: (1) Check all pipe flange before starting, sealing joints. (2) The start should be fully open suction and discharge piping valves, non-closing valve starts. (3) After verifying motor rotation direction, start the motor. (4) dynamic coupling plate, friction and collision sound. (5) for the first time should start within the transmission fluid injection pump. YCB arc high viscosity heat pump out of the shackles of traditional design, the gear pump in the design, manufacture and use to enter a new field. Botou day extension Pump Co., mainly produces gear pumps, rotor pump, stainless steel pumps, high viscosity pump, screw pump, heat pumps, marine pumps and other 15 series over 300 kinds of product specifications, complete specifications, wide application .
