1.      Summarize

ZXL Direct Connect Chemical Self-Sucking Pump is produced according to the relative technique from nation and abroad. All the technique guide line has reached the lead level in the world, and it has wide usage market and develop foreground. This pump has compacted horizontal frame, unitary motor and body, beautiful exterior, and small occupying area. Compared with common self-sucking pump, the occupying area is decreased 30%. If adopts IP54, it doesnt need pump room and can be used outside.

 

2.      Usage

ZXL Direct Connect Chemical Self-Sucking Pump is widely used for water supply and sewage drainage of municipal, environment protect, chemical, dyestuffs, petroleum, pharmaceutical, brewery, paper and pulp, metallurgical and mining industries and equipment cooling.

 

3.      Characteristic

It has the merit of unique frame, high self sucking capability, and it only need ration lead liquid before work, medium temperature: ≤80 special request: 200 the sucking height should below 5-6.5m the sucking length ≤10m, flux: 3- 200 m3/h outlet pressure: 5-125m rotate speed: 1450-2900r/m

Q:What are the conditions for the series and parallel connection of the pumps?
1, pump series, the two pumps must start and stop at the same time in order to normal operation.2 when the pump is connected in parallel, the two pumps must be equipped with check valve at the same time to operate normally.3, of course, in the election of the pump, should meet the requirements of upstairs said.
Q:Fully automatic self-priming pump
It's difficult to answer your question only from the name you give! There are many automatic self suction pumps on the market. Generally, the pump outlet is equipped with a pressure switch. It starts automatically when the pressure is low, and stops after a certain pressure.If the pump outlet is the pool (water tank), then it is not a simple "automatic self-priming pump".It is an automatic water supply system. The whole system includes water pump, water tank, liquid level meter, electromagnetic starter (contactor), switch and so on
Q:Water pump eliminates air
First of all, why should exhaust air, pump suction principle is the rotation of the impeller, pump water inside the throw out, and then let the inlet pipe into a vacuum. Then, under the influence of atmospheric pressure, the water pressure is pumped into the pump. Therefore, if the water is not filled, the sealing of the pump is impossible to pump the air inside the evacuation of high vacuum. In other words, do not fill the water, you can not smoke water. You can hear the noise in the pump when the water bubbles under the bottom vacuumThe water doesn't go up because it doesn't have enough vacuum!The reason 1 is because there is no water filling,2, because your pump and water vertical height higher than the pump itself suction stroke.3., the pipeline resistance is too large (including the pipe diameter is too small, elbow and so on)
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed water pump is the water pump for the entire boiler, and the water needed by the boiler is supplied by a feed pumpThe condensate pump is supplied to the deaerator after condensing the condensate from the turbineVacuum pump water jet pump should be said, to ensure the turbine vacuum pumpThe low drain pump is the power pump of the low temperature heater
Q:TDH what units are present in the pump parameters?
TDH, Total, Discharge, Head, that means the head, the unit is usually feet. 1 feet =0.3048 meters.
Q:What's the function of the engine pump?
The function of the water pump is to pressurize the coolant, and ensure that it circulates in the cooling system. Generally speaking, the water circulates continuously through the radiator, engine block and parts. Take away heat.. Ensure that the engine is not high temperature
Q:Safety head of water pump?
In fact, to prevent pipeline errors, generally take 0.5 meters margin, just in case the pipeline changes, resistance, and do not smoke Sheung Shui
Q:What does the lift of a pump mean?
Lift lift height = water raise height = total lift lift height + water = water is expressed in M by H (m)
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Mainly determined by the function of the water supply pump and the circulation pump.Replenishment pump is mainly to supplement the loss of the system, so the general flow is smaller, larger head, single pump water model in a small flow situation, many are not up to the required head, can only use multi-stage pumps.Circulating pumps are generally large flow, low lift, heavy efficiency, economic operation, and hydraulic model point of view, are single-stage pumps more appropriate, especially single stage double suction pump.
Q:What is called soft start of water pump?
Close the outlet valve of the pump, open the inlet valve, and can ensure that the water pump "self filling" (the liquid level is higher than the pump inlet pipe under the condition of the water pump start procedure is: to start the motor, to the normal operation of the motor, slowly open the outlet valve, the current gradually increase. But in the unattended operation (valve), and automatically pump, and pipeline diameter and length (in the pipeline water quality will be great), such as the motor start fast, to quickly promote the quality of water (as the train will soon accelerate acceleration), will make the motor starting current is large, causing the motor to trip and the damage of mechanical and electrical. Soft start (soft starter added in the circuit) - that is, slow motor speed, can overcome the above situation.Stop the pump normal order is: close the outlet valve, then stop the motor, such as unmanned operation, the outlet valve is not closed, when the pump stops suddenly, the water inside the tubes (especially vertical pipe), water will quickly turn back, so when the check valve suddenly closed, the fast flowing water suddenly stop by the inertial impact that produces "water hammer" effect and damage of pipeline system, using the "soft stop" should, in the circuit is connected with the soft stop device.
