HIJ type alkali pumpDetailed product description：

I. Overview

The HIJ type alkali pump is a single-stage single suction cantilever centrifugal pump. Its markings, rated performance points, and dimensions all comply with the GB5662-85 standard, equivalent to ISO2858-1975. It belongs to the same type as IH and IJ chemical pumps, but has been improved in structure to better adapt to the process conditions of the alkali industry. Compared with IJ alkali pumps, it has the following characteristics:

IJ type alkali pump	HIJ type alkali pump
The single volute design of the pump operates under high flow conditions with unbalanced radial forces, increased shaft deflection, increased pump vibration and noise, poor sealing effect and short service life of the mechanical seal, reduced reliability, and short maintenance cycle.	The double volute design of the pump (with a diameter greater than 80) ensures that the pump operates within the full flow range, with balanced radial forces, stable pump operation, increased reliability, and sufficient guarantee of the service life of the shaft, bearings, and seals.
IJ type mechanical seals require water cooling and flushing, and the cooling channel is small, which is prone to scaling and blockage, causing damage to the seal. Secondly, the water seal is a skeleton oil seal. Due to poor water lubrication, the oil seal quickly wears grooves on the shaft, causing cooling water leakage and resulting in the scrapping of the seal and pump shaft.	The special combination sealing design allows the pump to operate in all positions of the alkali production process without the need for water cooling and flushing, and extends the service life of the mechanical seal, saving water resources and solving environmental pollution caused by cooling water discharge, with significant economic benefits.
The bearing oil seal adopts spiral sealing, which has a large size space and is prone to overflow when the oil level is slightly high, which is not conducive to the operation and control of refueling personnel. If the cooling water leaks, it will enter the bearing box along the shaft and cause harm to the bearing.	Special oil seal design ensures no wear on the shaft and no oil leakage when the fuel tank is full. External impurities cannot enter the tank, and the oil seal has a lifespan of several years. It is easy for refueling personnel to operate and can save a lot of lubricating oil.
When transporting media with high solid content, the service life of the mechanical seal is relatively short, such as in the salt collection pump and salt slurry transportation of alkali evaporation process, the maintenance cycle of the pump is relatively short.	It is more suitable for transporting media with high solid content, such as salt collection pumps and salt sludge in alkali evaporation processes. The maintenance cycle of the pump can be several times longer than that of the IJ pump.
When the inlet pressure of the pump is positive, the sealing effect is poor.	It is more suitable for high-pressure and positive pressure working conditions of pumps, with ideal sealing effect and service life.

2、 Purpose:
The HIJ type alkali pump is not only used in the alkali production industry such as soda ash and caustic soda, but also in industries such as metallurgy, steel, acid production, petrochemicals, synthetic fibers and plastics, papermaking, pharmaceuticals, and environmental protection.

4、 Sealing of the pump
The pump adopts a combination of mechanical seal and our company's designed seal, and users can choose according to their own usage conditions.
5、 Precautions for users during use
1. When wiring the motor with the pump, users should first pay attention to whether the motor direction is consistent with the pump direction. The pump should be jog and tested for the correct direction before operation
that 's ok.
Before starting the pump, lubricating mechanical oil should be added to the bearing box, and the amount of oil should not be too much, preferably at the center of the oil gauge.
Before starting the pump, the coaxiality of the coupling should be rechecked, and the maximum outer circle error should not exceed 0.1mm.
When starting the pump, all the inlet valves of the pump should be opened first. After the pump reaches the rated speed, slowly open the outlet valve to achieve the specified working condition
Stop.
If a combination seal is not selected, the cooling water should also be turned on before starting when choosing a general machine seal.
