SCR urea pump is an important part of the urea solution injection metering system. Its main function is to extract the urea solution in the urea tank and maintain a certain pressure, then transfer it to the injection unit, to meet the flow and pressure requirements of the injection metering system.

The precision gear metering pump is a kind of rotor pump in the displacement pump, which consists of a stationary pump casing and a rotor that rotates. It has no suction valve and discharge valve, relying on the rotor in the pump body and the liquid contact side of the energy in the form of static pressure directly on the liquid, and through the rotating rotor extrusion effect of the liquid discharge.

dosing pump is a kind of special volumetric pump that can meet the needs of various strict processes, the flow rate can be steplessly adjusted in the range of 0-100%, used to transport liquids (especially corrosive liquids). dosing pump is also called quantitative pump or proportional pump. dosing pump belongs to reciprocating volumetric pump, used for precise measurement, usually requires dosing The stability accuracy of the dosing pump does not exceed ±1%.

precision gear pump plays an extremely important role in the machinery industry, in people's production life today, precision gear pump is widely used in many industries. precision gear pump is the main transmission device of mechanical equipment, oil pump overload in precision gear processing will have a great iMPact on gear processing, so how should this failure be solved? What are the causes of oil pump overload in precision gear pump machining?

Using the mechanical action of the pump, the low-temperature refrigerant is delivered to the evaporator. After throttling, the low-temperature refrigerant first enters the fluorine barrel with certain storage volume and certain gas-liquid separation volume, and then the fluorine pump conveys several times of the evaporated low-temperature liquid to the evaporator in each storehouse.
