Priming Pump

WFB series of seal-less self-control self-priming pump adopts no-leakage V-type seal assembly, eliminating the traditional pump packing seal, packing seal, mechanical seal, completely subdued the running, bubbling, dripping, leakingâ??, is to replace the original variety of long-shaft submerged pumps, submersible pumps, submersible pumps, etc. Ideal equipment. Disadvantages of the structure of the pump: First, downtime liquid leakage along the direction of the shaft outward, for frequent starting equipment is not very suitable for the occasion; Second, the power consumed by the secondary impeller is too large, the pump efficiency is low.WFB improved structure for the sealing device, one is to improve the efficiency of the pump, the second is to reduce the power of the motor, the third is to inhibit the leakage of the pump shutdown phenomenon. Sealing device in the movement process without friction, no wear and tear, the service life is more than 10 times longer than similar products. Transplantation of the vacuum pump principle, self-absorption performance is stable and reliable, in particular, the use of â??electric air control valveâ?? truly realised â??a diversion, life-long self-absorptionâ??. High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy to install, no need for foot fixing, eliminating the difficulties of transporting, installing and maintaining the long-shaft submerged pump. With superior self-control function, it can be used with high-tech fields and highly automated series.

We Manufacture REGENRATIVE SELF PRIMING PUMPS From 0.50H.P To 1.5H.P

Self Priming pumps are self priming centrifugal pumps , the dual seals of the pump consists of mechnical seals and sketleton seals, the pump is compact in constructure, fine in performance , convenient in maintain and saving about 50% water compare to furrow irrigation.

1. The trans medium's temperature to pump shouldn't be higher than 40degree;
2. Trans medium's pH VALUE: 6~8;
3. The grain diameter of the solids in the water is no bigger than 0.2mm
4. Single-phase pump
5. Self-priming pump, with high aborption and high lift-head
6. Brass impeller
7. Adopt skeleton-type oil sealing or mechanical sealing.
8. Based on general self-priming pump, automatic function is added and the pump can be applied to hot water.

When preparing to start the diesel dewatering pump for the first time, check the installation of all the equipment, start according to the following requirements: inject oil from the fuel filler into the diesel engine and the water pump suspension, and check the oil level with the dipstick to meet the required height; from the expansion tank to the diesel engine Add cooling water inside, the water level should be 2~3 expansion tank high; put diesel in the fuel tank, press the exhaust hand pressure pump, let the diesel enter the machine through the filter; connect the diesel water pump inlet and outlet pipes and gate valve, close the out Gate valve of water pipeline, outlet pressure gauge and vacuum pressure gauge; water or vacuum water supply to diesel water pump and inlet pipe, and evacuate internal air; open external circulation cooling water valve; start when inlet valve is fully open and outlet valve is closed Diesel engine water pump, when the diesel engine reaches normal speed, gradually open the valve on the outlet pipe and adjust to the required working condition.

When the diesel engine irrigation pump is running at high speed, the injection process takes only a few thousandths of a second. The pressure throughout the high pressure fuel pipe varies with time and position. Diesel can be compressed and has the property of pressure fluctuation in the high pressure oil pipe, which makes the actual fuel injection state and the prescribed oil supply law have a big difference. The composition, principle and characteristics of high pressure common rail diesel engine, and its current situation and development trend are introduced, which has certain guiding significance for the correct use of high pressure common rail diesel engine.
The combustion process of diesel pumps is very important for the operation of diesel engines. The advantages and disadvantages of the combustion process directly affect the power and economy of the diesel engine pump. The power and economy of the engine driven water pump is an important indicator to measure the performance of the diesel engine. Whether the combustion process of the diesel pump can be correctly, timely and completely will directly affect the power and economy of the diesel engine pump.
