Product Details

1、 Product Usage:

SHZ-95B Circulating Water Multi purpose Vacuum PumpCan be used for multiple students to conduct experiments simultaneously, reducing the experimental space. This product is specifically designed for configuring products such as rotary evaporators, double-layer glass reactors, vacuum drying ovens, vacuum filters, filter bottles, rotary film evaporators, multifunctional reactors, vacuum film concentrators, etc. It is one of the laboratory products. Circulating water vacuum pumps were initially used as self-priming pumps, and gradually became used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine, and food. In many industrial production processes, such as vacuum filtration, vacuum water intake, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain, and vacuum degassing, pumps are widely used.

2、 Product advantages:

1. Novel design; Easy to use, the pump head of this machine is directly immersed in water; No water kettle is installed; The overall height of the machine is relatively low; Small size; Lightweight; Convenient mobility; Desktop can be placed on the workbench for easy operation and observation. The top cover of the water tank is a movable installation that can be opened at any time for easy water filling and maintenance.

2. The series of products have dual meter and dual draw models; There are four types of suction, four suction, and five suction, which can be operated separately or simultaneously. Each suction nozzle is equipped with a suction gauge, which can easily observe the vacuum degree. A check valve is installed on the vacuum extraction path to prevent circulating water from flowing back into the equipment being evacuated when the vacuum extraction operation is stopped.

3. Corrosion resistant and pollution-free, the water pump components of this machine are made of stainless steel, and the water tank is made of ABS plastic. It is not affected by corrosive substances such as acid and alkali during one-time molding, and there is also no laboratory pollution such as oil stains.

5、 Usage: (Add water before starting up, do not run the machine empty)

1. The water inlet and level scale of SHZ-95 and SHZ-CA series products are displayed on the back of the box.

2. The water injection port of SHZ-DIII series products is located at the large mouth on the right side of the table (with the lid lifted). The water level standard is based on the upper water outlet on the back of the water tank.

3. Connect the vacuum container with a vacuum tube:

1) Single tube pumping: grouped experiment; Connect each suction port to a container.

2) Parallel pumping: If pumping a large container vacuum, a dedicated connector can be used in parallel to shorten the pumping time.

6、 Usage of external circulating water: During normal operation, there is no need to turn on the external circulating water. If cooling water needs to be provided to the reaction device, connect the outlet of the external circulating water to the inlet of the reaction device with a water pipe. Connect the outlet of the reaction device to the inlet of the external circulating water, and turn on the external circulating water switch. (Note: The external circulating water switch of SHZ-DIII pump is located on the back.). )

7、 The rubber hose on the back of the SHZ-95 pump casing is used for non-stop water change. When the water temperature rises due to long-term operation and needs to be changed, the rubber hose is connected to tap water; After opening, allow the wastewater to be discharged from the holes on the box.

8、 Maintenance method:

1. Regularly maintaining clean water quality is the key to the long-term stable operation of equipment. It is necessary to regularly change and clean the water tank. Cannot extract dust and solid substances.

2. Some corrosive gases can cause the water quality in the water tank to deteriorate, produce bubbles, and affect the vacuum degree, so attention should be paid to constantly circulating and changing the water.

3. For special highly corrosive gases, it is necessary to carefully determine whether they react with the materials used in this equipment and use them with caution.

7、 Common faults:

serial number	Common Faults	Search for location	exclusion method
1	The vacuum degree is not up or the vacuum gauge indicator is inaccurate	Insufficient motor speed or low voltage	Check if the voltage is stable
		Vacuum bottles and check valves are clogged or corroded with dirt	Clean up internal dirt or replace new bottles or valve cores
		Water inlet and filter mesh are blocked	Clean and remove internal dirt
		Impeller detachment	replace the impeller
		Vacuum gauge has water or air leakage	Discard the water from the meter's memory to reset the needle to zero or replace the meter with a new one
		Vacuum pipeline blockage or pipe cracking	Clean the pipeline or replace it with a new one
2	The motor is not working	The fuse is burnt out	Replace the fuse with a new one
		The operating capacitor is broken down	Replace the new capacitor with a voltage equal to the original capacity
		Motor winding burnt out	Replace the motor with a new one
		The bearing is severely worn and stuck	Replace the bearing with a new one
		The impeller is blocked and stuck	Remove debris and correct the position of the impeller
		Wire head virtual soldering or loose wire clip	Welding is secure, and the wire clip is tightly clamped
3	Motor overheating and excessive noise	bearing wear	Replace the bearing with a new one
		Wear and deformation of impeller	Replace the impeller with a new one
		Voltage instability or low voltage	Check if the circuit is overloaded or if there is any low voltage phenomenon
