Common sense of daily maintenance of the oil pump

1, heat pump shaft pump set in the front stuffing box, sealing performance is more reliable. It is normal to have a small amount of leakage early in operation, and the leakage will decrease or stop after the sealing surface has run through a certain period of time. 2, the transmission medium to heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, the temperature of the bearing seat to adapt to the shaft sealing performance temperature. Therefore, the choice of conducting oil pump installation location, make the pump cover and bearing seat of the heat easily spread, do not appear the phenomenon of heat storage. 3, bearing set with two bearings, each ball bearings running 3000 hours, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the new bearings. After 48 hours of operation, use a grease gun to inject replenishment grease into the pressure cup on the bearing cap. 4, not allowed to enter the pipe gate valve to regulate the flow, to avoid cavitation. 5, the heat transfer oil pump should not be less than 30% of the continuous operation under the design flow, if you must operate under the conditions, it should be installed in the bypass bypass pipe exports, and to flow above the minimum. 6, often check the loose bolts anchor situation, heat pump oil pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration. 7, pay attention to the existence of noise conduction heat pump operation, such as the pilot state was found to be timely manner. 8, downtime: cut off the power. The heat transfer oil pump liquid venting, cleaning and should regularly rotate the impeller 180 degrees to prevent shaft deformation until the pump is completely cooled so far.

Characteristics of 3003 aluminium sheet:



3003 is an AL-Mn alloy, which is widely used as a kind of rust-proof aluminium. Its strength is not high (slightly higher than that of industrial pure aluminium) and can not be strengthened by heat treatment. Therefore, cold working method is adopted to improve its mechanical properties: high plasticity in annealing state, good plasticity in Semi-cold hardening, low plasticity in cold hardening and corrosion resistance. Good corrosion, good weldability and poor machinability. It is mainly used for low-load parts which require high plasticity and good weldability and work in liquid or gas media, such as mailbox, gasoline or lubricant conduit, various liquid containers and other low-load parts made by deep drawing: wire rods are used as rivets.



The main alloy element of 5052 is magnesium, which has good formability, corrosion resistance, weldability and medium strength. It is used to manufacture aircraft fuel tank, fuel pipe, sheet metal parts of traffic vehicles and ships, instruments, street lamp brackets and rivets, hardware products, electrical-appliance shell, etc. (2) Al-Mn alloy is a kind of rust-proof aluminium widely used. It has high strength, especially fatigue strength: high plasticity and corrosion resistance, can not be strengthened by heat treatment, good plasticity in Semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, poor machinability and polishing. Uses are mainly used for low-load parts which require high plasticity and good weldability and work in liquid or gas media, such as oil tank, gasoline or lubricating oil conduit, various liquid containers and other small-load parts made by deep drawing: wire rods are used as rivets.
