Overview
Desktop vacuum pump is the latest designed desktop vacuum pump model with circulating water as working fluid, and it adopts jet technology to create negative pressure. It is not only a kind of vacuum suction device, but also supplies cooling water to the reaction device at the same time. It has the non-oil, free-pollution, anti-corrosion, low noise, easy to move and so on features.
SHZ-95B is a once forming anti-corrosive shell with five taps new pump, which is improved on the basis of all stainless steel five taps in SHZ- C type desktop vacuum pump. The taps can also wok alone, or paralleled to get more vacuum. It can meet the needs of larger rotary evaporators and glass reactors, which also serve many devices at the same time.
Desktop Vacuum Pump Application:
It provides vacuum condition for evaporation, distillation, crystallization, drying, distillation, filtration pressure, vacuum degassing experiments. Especially suitable for colleges and universities, research institutes, chemical, pharmaceutical, biochemical, food, pesticides, agricultural engineering, biological engineering etc industries’ scientific research, pilot and production.
How to use the desktop vacuum pump:
Open the upper cover of the water tank, pour clean cold water, and the water level should be slightly lower than the overflow nozzle. Connect the power plug, turn on the start switch, and the pump starts to work. Block the nozzle with your fingers, and the corresponding vacuum gauge can reach a vacuum close to -0.1Mpa, indicating that the pump is working normally.
Features
Desktop Vacuum Pump Features:
(1)One machine with multi-pipe operation, where three sets (five sets )of air exhauster are fixed and can be used independently or parallelly, compared with desktop pump, swept volume is bigger, applied to large swept volume vacuum needs.
(2)Corrosion resistance, free-pollution, stable performance, low noise and durable.
(3)The tank is made from Polyvinyl chloride plastics, free-pollution; The shell adopts stainless steel material or static spring plastic.
(4)Host stainless steel movement and anti-corrosive movement models.
(5)The water-line target, light shows high, medium and low.
(6)4 trundles make the movement easily
(7)The air exhaustor, three links, check valve, suction nozzle are made of PTFE, anti-acid and alkali.
(8)Pump body and impeller are made of corrosion protection polypropylene.
(9)Special customized motor by well-known manufacturers, fluorine rubber mechanical seal to keep no corrosive gas into the motor.
(10)There are several sets pumping system inside the pump. Three or five sets taps are installed in this model, alone or in parallel. Compared with desktop pump, it has larger amount of exhaust, in particular suitable for big device’s demands.
Desktop vacuum pump maintenance method:
1. Keeping the water clean is the key to the stable operation of the equipment. The water must be changed and cleaned regularly. Dust and solid matter cannot be pumped. Certain corrosive gases can cause the water quality in the water tank to deteriorate, produce air bubbles, and affect the vacuum degree, so attention should be paid to changing the water in a continuous cycle.
2. For special strong corrosive gases, it should be carefully judged whether it reacts with the materials used in this equipment, and used with caution. If the vacuum does not go up, first judge whether the pumped container is leaking or the leather tube is loose. If it is a pump problem, check whether the water inlet or each air circuit is blocked or loose and leaks. If the motor does not turn, check the power supply or fuse. Check whether the desktop vacuum pump pipeline and joints are loose. Turn the desktop vacuum pump by hand to see if the vacuum pump is flexible.
3. Add bearing lubricating oil to the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or replenished in time.
4. Unscrew the water diversion screw plug of the pump body of the desktop vacuum pump, and pour water or slurry. Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the water outlet pipeline.
5. Start the motor, and try to see if the direction of the motor is correct.
6. Start the motor. When the desktop vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After seeing the appropriate pressure, open the gate valve gradually, and check the load of the motor at the same time.
7. Try to control the flow and head of the desktop vacuum pump within the range indicated on the label, and operate the desktop vacuum pump at the highest point to obtain the greatest energy-saving effect.
8. During the operation of the desktop vacuum pump, the bearing temperature should not exceed the ambient temperature by 35°C, and the maximum temperature should not exceed 80°C.
9. If abnormal sound is found in the desktop vacuum pump, stop the machine immediately and check the cause.
10. When the desktop vacuum pump is to be stopped, first close the gate valve and pressure gauge, and then stop the motor.
12. Frequently adjust the packing gland, and the dripping in the stuffing chamber is normal, and it is advisable for the drip to leak out.
13. Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large.
14. When the desktop vacuum pump is used in the cold winter season, after parking, it is necessary to unscrew the water discharge screw plug at the lower part of the pump body to drain the medium. Prevent frost cracking.
15. When the desktop vacuum pump is out of service, it is necessary to disassemble the pump completely, wipe off the water, apply grease to the rotating parts and joints, install them, and keep them properly.
