Pump works are what

manual gas pump: The engine crankshaft via two belt-driven air pump, which drives the piston pump, hit the gas through a pipeline to import gas cylinder. On the other hand accumulator and through a gas pipeline to the gas introduced into the gas cylinder is fixed to the pump's pressure regulator to control the gas cylinder pressure. When the gas pressure within the regulator set-Jane's pressure is not reached, the gas enters the regulator from the gas cylinder pressure regulator valve can not open items; when the gas cylinder pressure regulator adjusted to achieve the predetermined pressure when entering the regulator from the gas cylinder gas pressure regulator valve to open the top, into the pump in communication with the regulator airway and controls the pump inlet through the airway normally open, so that the pump empty load operation , to reduce power consumption, pump protection purposes. When the gas cylinder pressure regulator due to wear and tear and it is set lower than the pressure within the regulator valve return spring to return, disconnect pneumatic air pump control, mechanical pump. My personal solution is crooked between accumulator and catheter valve, cheer when the gas pressure to the inside because the outside world opened up when mentioning the reason because the intake is closed, so accumulator sucked outside air rather then playing into the air sucked out.

Use and maintenance of small tanker vane pump

In the process of using a smalldiesel fuel dispenser, vane pump requires frequent inspection and maintenance.
First, when the test machine and cleaning the tank, can not use water or aqueous oil tankers, in order to avoid the cracking damage diesel transfer pump and other components of internal corrosion and low temperatures.
Secondly, we should regularly clean the filter, especially the newly installed machines and pipes and even more so. With the increasing use of time, dirt tank and pipeline will reduce, filter cleaning cycle can be extended, but generally not more than a month.
Always check again vane pump operation is flexible uniform, without abnormal noise, shaft and pump cover at leaks, pulleys for excessive runout and wobble like.
At the same time the relief valve spring can not be adjusted too tight, otherwise it will make the system pressure, noise and vibration increases, and increased pump bearing wear.
Finally belt tension should be appropriate, the tension is too small, the belt slippery, causing oil shortage or not oil, but also easy to wear belt tensioning force is too large, the motor shaft and the pump shaft is exposed to additional load (axial direction of the vertical axis) increases, could easily accelerate the motor bearings, pump bearings and seal wear.

When you start refueling tanker, the flow rate is slow

A mechanical pump filter clogging (including cone filter and oil filter gun); 2, tanker or pipeline leak components lead to a lot of air into the gas into the vane pump Separator greater than the maximum amount of gas. Boot test, oil separator exhaust pipe will exhaust blows, and depending on the oil at a large number of bubbles. Maintenance should first check whether the parts tanker leak exists, then check the oil line and bottom valve Mifengbuyan problem; 3, vane pump failure; ① vane pump or pump relief valve closed lax anti-pad wear, damage is also one of the reasons for the slow drain vane pump; ② badly worn blade or vane pump with debris stuck to the blade, resulting in the individual blades can not pop, but also make the inner vane pump discharge increases, the oil tanker discharge rate change slow. 4, oil separator fault ① oil separator or small float off into the oil, a normally open valve leading to insufficient pressure hyperbaric chamber; ② oil separator too much debris in the lower part of the oil valve resorted to the oil valve can not be effectively open; ③ manual gas pump separator pressure pad superstructure damage, resulting in insufficient pressure hyperbaric chamber Mifengbuyan, drain slower.

Gas pump including

Pumping the container using mechanical, physical, chemical, physical and chemical method, in order to obtain and maintain a vacuum device. Vacuum manual gas pump and other equipment (such as a vacuum container, vacuum valve, vacuum measuring instruments, the connection pipelines) consists of vacuum system, widely used in electronics, metallurgy, chemical industry, food, machinery, pharmaceuticals, aerospace and other departments. According to its working principle, basically divided into portable fuel gas transfer pump and pump gas trapping two types.
Widely used in chemical, food, building materials and other departments, especially in a vacuum crystallization, drying, filtration, evaporation and other processes more appropriate. Rotary vane vacuum pump is used for extraction is one of the basic equipment of gas container. It can be used alone, can also be used as a booster pump, diffusion pumps, molecular pump. This type of pump is widely used in metallurgical, mechanical, electronic, chemical, petroleum, pharmaceutical and other industries for vacuum metallurgy.
